SpaceChain Foundation is excited to announce that our blockchain hardware embedded with the multisignature wallet technology has been installed on the International Space Station (ISS)! The installation was conducted by astronaut Jessica Meir, who is also a marine biologist, physiologist, and more recently, the participant of the first all women space walk.https://medium.com/media/3f5e2546ebf776acca7d511bb5ee9839/hrefOur second-generation blockchain hardware (Fig. 1) is housed in a 1U NanoLab (Fig. 2) that is designed by Nanoracks. Thanks to the modularised features of the hardware, astronaut Jessica Meir is able to easily plug the NanoLab into the research platform via a USB port to power up our hardware. This allows us to send data and command files from the ground station to our ISS hardware, and vice versa. Check out how the full installation was done here.Fig. 1: SpaceChain Foundation Blockchain Hardware — second-generation flight-tested ZYNQ board (IPC-A-610 Class 3), Linux OS, dual ARM Cortex processor, gigabyte ECC memory, and EMI shielding.Fig. 2: A 1U NanoLab module (10 cm x 10 cm x 10 cm). Photo: NanoracksWhy put blockchain in space?In a standard terrestrial blockchain transaction, one private key is used to complete a transaction which is then broadcast to the network. If that private key becomes known by a malicious entity, all of the funds can be lost. Multisig (multisignature) technology requires more than one private key approval in order to authorise a transaction, rendering the transaction vastly more secure than standard single-signature methods. Furthermore, multisig mechanism provides an effective way of managing accounts/assets that are jointly held by multiple parties. The SpaceChain Foundation implementation adds the remoteness and security of low-Earth orbit infrastructure to multisig to create something entirely new.“The integration of space and blockchain technologies has uncovered new possibilities and opportunities and we are very excited about the prospect of working closely with financial service providers, fintech and Bitcoin developers, IoT service providers, research institutions and space agencies in the coming months to further accelerate advancements within the ecosystem,” said Zee Zheng, SpaceChain co-founder and CEO.This opportunity was provided via Nanoracks and their Space Act Agreement with NASA. The launch aboard a SpaceX Falcon 9 took place from the Kennedy Space Center on 5 December 2019. Read more here.

The Open-Source Revolution ...

As part of our series of interviews with space and blockchain industry thought leaders, we had a chat with Fossa Systems’ Chief Executive Officer and Co-founder Julian Fernandez about issues around picosatellites, open-source space and the future of the space industry.Fossa Systems is dedicated to the development of open- source picosatellites enabling experimental worldwide IoT connectivity and democratising space. Learn more about Fossa Systems here and check out their GitHub repository.1. What made you decide to set up Fossa Systems?Julian: My interest in space and COTS hardware spans back to 2017 when I started working on femtosatellites (Sub 100g spacecraft). I have also worked on various IoT related projects for remote asset monitorisation. This last experience further taught me the need for remote IoT connectivity.Fossa Systems was initially created in response to the market need for inexpensive and fast solutions regarding worldwide connectivity. Our goal is to democratise access to space and telecommunications as a hardware manufacturer. This means developing inexpensive satellite platforms and operating these low-cost systems.We actually started Fossa Systems as a non-profit project on an online forum in 2018. Back then, we were students and needed a cheap way of getting to space.2. How does a free and open-source mentality contribute to the development of the New Space industry?Julian: Our name Fossa Systems indicates Free Open Source Software and Aerospace Systems. As such, open source is a major part of our business model. We believe it is imperative that we develop space technology in an open manner for the benefit of all.This can be perfectly linked to a successful business model as we are demonstrating with the launch of three satellites to this date. New Space is a rapidly developing and advancing industry where secrecy only constitutes an impediment to the general advancement of the market.3. Tell us more about the FossaSat-1 and FossaSat-2 satellites and their applications.Julian: Having learnt from the design of the FossaSat-1 satellite, which we launched in December 2019, we made improvements to the architecture and developed the FossaSat-2. This new picosatellite platform caters to the current market need for Low-Earth Orbit (LEO) telecommunications constellations and performance-oriented integrated solutions for customer payloads such as radio modules or Earth Observation (EO) sensors.Based on the PocketQube platform, the FossaSat-2 is only 5x5x5cm big, and weighs a mere 250g. Its compact size and weight greatly reduces the current cost for access to space. Plus, it costs under 40,000€ (USD$44,000) for access to a 500km LEO with existing brokers.Both the FossaSat-1 and FossaSat-2 are mainly used for telecommunications and are initially being tested with these payloads. But, they can also be used for other mission specific payloads such as EO cameras. In fact, the FossaSat-2 will be flying the first camera on a picosatellite into space.You can find out more about each satellite here.4. What will be the real-world applications for Fossa System’s work on LoRa technology for the internet of things?Julian: LoRa was successfully tested on the FossaSat-1 satellite that we launched in December 2019. LoRa allows 3€ terminals to communicate with a satellite within ISM band limitations. It truly constitutes a major breakthrough in modulations that will allow the creation of global low-power IoT constellations.We are currently planning on using our future LoRa services for remote asset management and other non-accessible terminals.5. Which partners have Fossa Systems worked with in developing and launching your picosatellites?Julian: Fossa Systems has been mostly funded by Everis Aerospace & Defense, a company of the NTT Data Group. We have worked with various large aerospace companies on the development of our technology and have most recently started working with the ESA Galileo Science Office for flying GNSS receivers on our satellites.6. What are some of the biggest challenges you have faced in building Fossa Systems?Julian: Building a New Space company definitely is not an easy job. It is such a new market and we are always adventuring into unknown territory. Our biggest challenge has already been undertaken with the launch of our first satellite. The next challenge is to establish ourselves as a respected and trustworthy hardware provider in the industry. We are also still studying the challenging possibility of offering services using our hardware in LEO.7. Can you share some of your plans for Fossa Systems for the next couple of years?Julian: Fossa Systems is in the process of registering a more formal commercial division to further advance the professional development of Fossa’s satellites in the growing market. Fossa Systems will always keep its initial values and objectives as a priority. We are opening our office in Madrid in the coming months and are looking to professionalise our production chain to take on more serious contracts.8. How do you see the space industry developing in the short and long term?Julian: With regards to the evolution of satellite size in the industry, we are definitely going to see further miniaturisation and advancement of COTS technology for LEO. I believe large mega constellations do not pose a serious risk to the market we are targeting regarding IoT, but they are starting to pose a serious risk to the cluttering of orbital planes.This year alone we have had three close calls between our FossaSat-1 and one of Elon Musk’s Starlink satellites. The COVID-19 pandemic also poses a serious effect on the short-term investment in satellite businesses (as apparent with the bankruptcy filing of OneWeb), but in the long term, I believe we will ultimately recover.9. Which space technology developments most excite you?Julian: We are very excited about the development of electric propulsion and are actually flying Pulsed Plasma Thrusters from Applied Ion Systems as one of our payloads. We look forward to seeing what electrospray technology brings to the table with regards to in-orbit manoeuvring technology.10. How do you see blockchain contributing to the space sector?Julian: Blockchain has actually been on Fossa System’s radar since its creation. We believe it will have and is already having a significant impact on the way we are able to safely communicate and store data in a decentralised manner. We are starting to see immense progress in this field such as the use of cubesats for carrying out blockchain transactions in space.11. What advice would you give to young entrepreneurs thinking about starting their own space startup?Julian: It is important to have a clear and differentiating goal when creating a startup. There are lots of competitors in the New Space market at this stage, and lots of them have years of experience behind them. Patience and determination is important, but what seems like the most important quality is speed. Clients expect fast turnaround solutions, and in this industry, you have to constantly run to keep up with the rest. In part, this is our philosophy at Fossa Systems which is quite distant to what we see in larger and older satellite hardware manufacturers.12. What are your thoughts about the Decentralised Satellite Infrastructure (DSI) that SpaceChain is leading and developing?Julian: As a hardware manufacturer and service provider, we see SpaceChain’s ideas of creating a DSI completely align with our ideas and values. We hope to be able to work with SpaceChain on implementing and getting their technology into LEO using our platforms.Click here to check out our other interview series with SpaceChain COO Alessandra Albano.Keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.The Open-Source Revolution in Outer Space was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

AMA with Jeff Garzik and Je...

Topic of Discussion: An open-source hardware platform for Direct Satellite-to-Devices CommunicationOn May 28, 2020, Jeff Garzik and Jeff Dionne held an AMA on Reddit.Jeff Garzik is the CTO of SpaceChain Foundation. He is known for being the key Bitcoin core developer who worked under Satoshi Nakamoto for two years. His work can be found in every bitcoin and miner.Jeff Dionne is the CEO of Core Semiconductor. He is known for uClinux, from which most embedded Linux systems are derived, and developing many other game-changing embedded systems hardware and software technologies.Garzik and Dionne have always been passionate about pushing the boundaries of space and blockchain applications; a few of the past projects they have worked on are Linux kernel and Bitcoin Core.They love to share more about their experiences being in their respective industries, such as the formation of the open-source industry, open hardware, fabless semiconductor development, nano-satellites, cryptocurrency, and more.In this AMA, they discuss their development for their latest project — an open-source hardware platform that is capable of providing a downlink to mobile phones and small devices directly from satellites in orbit — all without the use of a satellite dish on Earth or a third-party network.Here are some of the highlights:1. What is in your opinion the best node or process to target when optimising price to performance ratio and having a low digital chip volume? What processes can we expect from the first Silicon running J-Core?Dionne: It’s just my opinion… it depends on the application (maybe you can elaborate). At the moment with that caveat and in general terms, I’d probably say 55nm. It’s a commodity process and every fab offers it. But take that with a grain of salt, to properly answer the question I’d want to know the application but also the gate count, budget and what performance means to you. I’m assuming you’re talking about a general purpose embedded application with a CPU.We’re working on a customer project that has a chance to be the first tapeout for CoreSemi in late 2020. Depending on their volume, we’ll probably target 55nm, but we already have some (not portable) IP blocks in 152nm from a previous design we could leverage.There is also the idea that we might try and do a fully open (right down to the standard cells and IO pads) design that the community could reproduce. That would be 350nm, because shuttle runs are on the order of $10k.The first application processor for J-Core will likely be quad core on 28nm, but that is a ways out yet.2. That large process size sounds a lot like what https://libresilicon.com/ is targeting. Have you looked into them?Dionne: Yes, and also relevant is http://opencircuitdesign.com. Part of the problem with using smaller process nodes in a completely open design is the NDAs that are needed. There are actual fab design rule documents that can be had for older processes… Once the business model of completely open designs has been proven to the fabs, we are hoping the situation improves.Still doesn’t solve the issue that 180nm might be within reach of an open hardware Crowd Supply, but 28nm isn’t really.3. What is the current performance of your GNSS implementation in terms of sample per min, latency and accuracy? Is there room for some more light computation on the current JCore you are using like drone flight control or robot control?Dionne: The released GNSS RTL https://github.com/CoreSemi/gnss-baseband is designed to produce one output from the hardware engine to the host CPU every 1 ms. It’s the task of the software part to turn those raw samples into fix updates (for location). So the answer is updates can be as often as you take outputs from the software tracking loops and run the solution solver. We’ve not yet released the software side, probably that will take a few weeks or a month. We previously used this engine for precise timing, in overdetermined clock mode, and that isn’t in general what the community will want.In a drone application, a dual J-Core SoC on an FPGA is definitely sufficient, a configuration that is basically a sweet spot for size and cost of the chip. If we were to put that on an ASIC, you could use a fairly cheap process and have plenty of DSP capability for flight control etc.Would such a chip, or an FPGA board with a form factor useful for drone/robot control be something you think would be interesting?4. Today’s setup for precision GPS requires RTK, so you end up with additional hardware. People are flying drones or driving robots on RPi, and so the size wouldn’t be a problem for a Turtle board. There is hat for RPi for this kind of application, but they aren’t really open hardware ( https://emlid.com/navio/ ). Just finding which pins emlid use is not obvious… I would think there would be some interest in a high precision drone setup that fit in a RPi format.Dionne: Ok, thanks for the feedback. The receiver board that CoreSemi and SpaceChain put together fits on the Turtle Platform… We intend both of those to go up on Crowd Supply. We’re working on it, and we intend to do it in the next few months, but that has been slow going so no promises just yet.Hearing there is interest definitely helps.5. Did I miss the J32 release? If not when will it be out? Also how can the community help Core Semi?Dionne: Coming up this summer. Software generally takes longer than hardware, J2 is well tested and supported by everything from the compilers to OS and application side, J32 CPU hardware needs that complete package before it can see wide use.If we engage with the community to test and port software to the J32 platform (when released), that will be a great help in getting there. In the meantime, clone our repos, support our Crowd Supply, and support our partner SpaceChain whose support made these releases possible.6. I am interested in knowing why SpaceChain decided to invest in Core Semiconductor when it is less than 6 months old?Garzik: CoreSemi’s team and technology are much older than 6 months. The team has been involved in Linux and open source for 15+ years, and at the time had already developed a clean room implementation of the Hitachi SuperH processor (dubbed “J-core”), with themselves and some of the original Hitachi chip engineers.SpaceChain wanted to help that team revive and market this open source hardware, as a fresh base for a new line of chips that can be used in space as well as on the ground.SpaceChain has an interest in having open source hardware widely used — “with many eyes, all bugs are shallow” — investing in CoreSemi acts as a force multiplier for Spacechain and the whole open source ecosystem, which largely runs on closed processors today. The security value of open source means we can change that.7. How can CoreSemi justify going with J-Core (SuperH) when RISC-V is all the rage? What relationship do you see J-Core having with RISC-V?Dionne: We see J-Core and RISC-V existing in slightly different application spaces. J-Core arguably has better instruction set characteristics for deeply embedded applications (such as this GNSS / Downlink) and RISC-V is designed more as a competitor to ARM.Both cores have the goal of democratizing the space, the differences in design philosophy with J-Core (SHCompact ISA) being more like an x86 with highly encoded, compiler friendly instructions. No one can argue that approach doesn’t have application. IMHO RISC-V is emphasizing clean and simple, directly implemented pipelines. Having both gives us all choice. In fact some of SpaceChain’s engineers are core developers of a well known RISC-V implementation called Hummingbird E203.8. Because of COVID-19 there will be no in-person conferences where you could present J-Core and recent developments.Do you plan to do long form presentations/podcasts where you tell us about what’s next, why things always take longer, what sessions you learned etc?Dionne: Community engagement is important to us. We think given the constraints on in person presentations, the best plan seems to be a series of videos (YouTube and probably lbry.tv). Things do take longer than one imagines or would like, but the reason for that is never problems with the technology.One thing I’d say we’ve learned is that there is no substitute for clean, buildable and well documented releases of the technology that have a hardware platform people can get their hands on. That is different from the pure open source software only model, and it’s a limiting factor for growth of open hardware. So we set out to change that. Our plan to do that is this:Build a production version of the Jx FPGA platform (turtle board) (done)With our partner SpaceChain, develop an application people can use (GNSS, and Downlink for things like IoT command and control, cryptographic hashes for light wallets, etc). Make the ‘hat’ board for that open also (this announcement)Release the RTL (done), and then the software (in progress)Get these kits into the hands of developers so they can build on top of our workBegin publishing videos to show how to do that.Numbers 4 and 5 are obviously one response to the global situation, but also have the benefit of producing artifacts people can work from in the future.9. Garzik, I recall multi-tenant computing on satellites being mentioned. What do you see as use cases where tenants want to run code on satellites?Colour me naive but the only thing that strikes me is access to the sensor data of the satellite but I guess it would be cheaper to just send the complete data down and process it on some normal computer?Garzik: The existing satellite industry model is: one sat owner, one operator (often same as owner), and closed software, usually for a single purpose.With modern software sandboxing, we can open that model up, making a — arguably risky — move to permit customers to upload their software. That’s brand new to the satellite industry, even though it is familiar and boring to the mobile phone and blockchain industries, where multi-app is normal.Opening up the closed satellite industry model is key to making access to space less expensive and more egalitarian.10. Do you have any use case examples where it would make sense to run my code above the clouds and instead of in the cloud?Garzik: It was a point of economics: the more people that access a satellite, the lower the cost, which creates new business models that are not possible today due to higher costs, as well as making existing space business models much lower cost.With regards to use cases, there are a few categories:The software is associated with a specific type of satellite payload (usually a type of camera or other sensor), authenticating and encrypting the data directly at the physical source. Multiple tenants can securely share physical satellite resources. This can only be done at the physical device, which is located in space.Increasing the number of spacecraft throughout inner space, LEO/GEO, produces the need to avoid going space-to-ground-to-space for a number of different applications. In-space processing is faster due to the laws of physics.Elements of space settlement. Businesses that want to explore space jurisdictions have already existed, but never before had a meaningful way to truly operate off-planet in a way that matches the org’s decentralised / resilient goals.Those business models that were created by entrepreneurs, just as the Internet itself spawned many new businesses and business models not thought of when the pre-Web engineers were sending text-based email to each other.11. When can we see actual use cases for SpaceChain? Does it have any real use case since it is a utility token?Garzik: Space business occurs on frustratingly slow timescales! I wish the world would go faster.Ultimately, it takes a long time to build a space network.The space network will use tokens for (1) network registration, (2) network access, and (3) one of several payment methods for space-based activities such as remote sensing, remote imaging, transmission, data storage and more.We are working on that specific whitepaper right now. We call it “DSI”, the Decentralized Satellite Infrastructure. Keep an eye on https://github.com/dsi-org12. Will people be able to contribute to the whitepaper? I am very interested in contributing to the whitepaperGarzik: Yes, the whitepaper will be one of the repositories on the Github. It will be open to contributions for a couple months, then frozen.13. I’m curious how you are going to bring some kind of economic value to investors of SPC?Will it be for the usage of the network? Or are you planning to maybe move to some kind of DAO situation?Garzik: There are at least three targets for the SPC token: network access, network usage, and payment. The general thesis is that everyday SPC holders benefit from there being demand for the token, generated by people acquiring the token in order to use it for space services, both terrestrial services as well as in-space services being paid for with SPC.14. You keep claiming SpaceChain is open source and decentralized. So far there has never been any repository open to developers.

Space Law Decoded

All you need to know about how peace and order is kept in outer spaceImage Credit: PixabayThe topic of space law flows into several grey areas that stump even the most seasoned of professionals in the field. Are there set laws that govern the space realm? Who has intellectual property (IP) rights in outer space? Does any one country have more jurisdiction than the other? Is it the Wild West up there where anything and everything goes?The short answer to the above is that the arena is likened to a global commons, a realm of shared ownership such as the high seas, our overall atmosphere and the Antarctic. This basically means that every participating party or nation is responsible to cooperate in maintaining the landscape for the good of present and future civilisations.Image Credit: UnsplashFive treaties to maintain peace and orderThe United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS) has five treaties in place that create parameters and boundaries to guide the industry forward.The first of these treaties, and perhaps the most well known of them among industry experts is the Outer Space Treaty of 1967. This basically presents principles for space exploration and operation, stating such terms as no nation can own space, the Moon or any other celestial body. Other terms of the treaty can be accessed here.The second treaty is the Rescue Agreement that outlines the obligations for any party that becomes aware that the personnel of a spacecraft are in danger. This means that if any participant in the space industry becomes aware that the personnel of a spacecraft are in distress, they must notify the launching authority and the Secretary General of the United Nations.The third treaty is the Liability Convention that establishes regulations for any damage in outer space. This was the treaty that was referred to when the Soviet Union was penalised after one of its nuclear-powered satellites crashed in Canada in 1978.UNCOPUOS has also established a fourth treaty named the Registration Convention that empowers the UN Secretary-General to maintain a register of all space objects.Last, but not least, is the Moon Agreement that requires all exploration and use of the Moon and other celestial bodies to be the province of all mankind, carried out for the benefit and in the interest of all countries. This basically means that the Moon should be used for the benefit of all states and all members within the international community.Image source: PixabayIntellectual property laws in outer spaceIt should be noted that several of the space treaties mentioned above were penned at a time when space exploration was still largely government driven. Since the landscape today has opened up considerably to private enterprise, many smaller businesses are concerned about their IP rights. It should be noted that the fundamentals of those treaties stay the same in this day and age.The Outer Space Treaty states that the national laws of the state in which a particular space object is registered in extends to the object. It also states that the country of registry retains jurisdiction and control over the space object and over any personnel thereof unless otherwise agreed among the launching States.This means that if a satellite is launched from Country A, or if a company from Country A purchases a launch, the satellite can be registered to Country A, and Country A’s (IP) laws will apply to the satellite.Image source: UnsplashLegal implementation an uphill taskAlthough seen largely as positive frameworks to regulate space travel, the space treaties in place have at times proven to be more effective in theory than when it comes to their implementation.Take the issue of space junk, for example, where damage caused by debris floating around in outer space is not covered explicitly by the five treaties. Establishing the causality of damage caused by space debris has also proven to be a challenge — it is often difficult to identify particulate debris and trace it back to the owner of the original launched object. This can become quite an issue of contention, seeing that there are [hyperlink to space junk blog] 34,000 debris objects in orbit that are larger than 10cm in size!Another example of where space law tends to remain ambiguous is when it comes to the militarisation of the industry. Although the Outer Space Treaty deems that space should be used exclusively for peaceful purposes, there is no prohibition on setting up military bases, conducting weapons testing, or bringing weapons into outer space. Opponents, however, feel that the construction of military bases in outer space could lead to war in the future and that legalities surrounding the issue should be made clear to maintain peace in outer space.Keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.Space Law Decoded was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Moving towards a Decentrali...

In the first of our new series of interviews with space and blockchain industry thought leaders, we sat down with Chief Operating Officer Alessandra Albano to find out more about her role with SpaceChain and where the blockchain industry is heading in the foreseeable future.Could you tell us a bit about your professional background as well as your role with SpaceChain?Alessandra: I come from an operations background that has seen me specialise in designing and developing decentralised ecosystems for large blockchain projects. My areas of expertise also span from all matters of compliance to establishing strategic directions for clients across the blockchain space.At SpaceChain, my main role is to make sure that all processes are in place and run smoothly. It is my responsibility to plan all resource allocation and ensure that their distribution allows for maximum efficiency. I am also the go-to person when it comes to business strategy.On any given day, my role may see me involved in the evaluation of potential business opportunities and collaborations, product launches, commercialisation initiatives, public positioning of the company as well as the sourcing and acquisition of new talent. I also work closely with the R&D, partnership and tech teams to source funding and apply for grants as and when necessary.You recently conducted an inspiring workshop on how blockchain will be the next big disrupter in outer space. How will the integration of blockchain technology shape the evolution of the industry?Alessandra: It is evident that the space industry is becoming more and more of a conduit to allow legacy companies such as those in the defense and military spheres as well as publicly funded organisations to evolve into fully commercial enterprises.Many of these companies are currently going through tough times, feeling the economic impacts of a global pandemic. I strongly believe that innovation is the one factor that can create the bridge for these organisations to get back on track. This is where blockchain technology can play a large role, leveraging space infrastructure to enhance existing terrestrial blockchain networks (for example, by amplifying reach or increasing its resilience).Blockchain technology can also bolster and strengthen existing space infrastructure by enhancing the opportunities for secure data sharing amongst commercial partners. We will see a rapid shift towards blockchain solutions going far beyond cybersecurity and cryptocurrencies in the near future.In your opinion, what are the main challenges that the industry is facing, particularly when it comes to its overall governance?Alessandra: As with any industry that has experienced exponential growth during its (relative) infancy stage, I feel that one factor that the public needs to take into account is the fact that there will always be road bumps along the way. Many blockchain projects may seemingly be running out of steam, but if one were to take a closer look, there is still a lot of growth and innovation taking place behind the scenes. This may not be that obvious to the general public due to the incremental rate of this occurring.This is one of the main reasons behind a lot of stigma and lack of understanding across the industry. There is mind-blowing work being done by tech experts within the blockchain sphere, and the public needs to remain patient and trust that the sense of community and vision for the sector remains strong and unfazed through the development stage.The revolution of decentralised governance, which many are awaiting, will undoubtedly happen, but only after the technology itself becomes more resilient. After this, we will see more widespread and universal adoption by the wider business world.How will SpaceChain’s technology help to mitigate these challenges?Alessandra: Like everyone else in the blockchain community, we are working towards gaining visibility, trust and acceptance from legacy industry players. When it comes to SpaceChain, our main audience is the aerospace industry, which comes with its own set of challenges. We are essentially the only ones in this area (integrating blockchain in space) so the journey is a bit challenging but not one that we are not fully equipped to scale. This has been demonstrated in our success so far, working together with market leaders such as Nanoracks as well as collaborating in cutting edge research projects with companies like Deimos. A huge milestone for us was when we obtained funding and support from the European Space Agency (ESA).One of our main objectives is to prove that blockchain applications within the wider aerospace sector can bring benefits to existing players. We have already had three successful launches, released a groundbreaking industry-first OS that allows for multi-tenancy and earned our stripes as a space company with our custom-developed hardware.The next step will be centered on finding software applications for the industry using blockchain, and I can’t wait to find new ways to bolster and strengthen the entire community through our developments.What excites you most about the future of the blockchain industry?Alessandra: As I said earlier, the industry is still at its infancy stage. We are merely warming up and nowhere near experiencing its full potential.I would like to see examples of decentralised ecosystems running at capacity and economic implementations tested for mainstream adoption. I am extremely thrilled whenever I see tokenised applications starting to develop. An example that comes to mind is the Brave browser and its tokenised rewards system. Even closer to home (although geographical barriers mean little in the industry), we have the ride sharing Tada that rewards drivers and customers with utility tokens.The potential for such applications are limitless, and it will only be a question of time before widespread adoptions from existing businesses materialise. I am also looking forward to a fast track journey towards national digital currencies, which I hope will eventually succeed at mitigating the risks and impact of global recessions just like Satoshi intended when he conceived Bitcoin.What do you enjoy most about your role with SpaceChain?Alessandra: I would have to say that the one thing that makes me love coming to work is my team. They are a bunch of talented and considerate people and I feel extremely fortunate to work with them on a daily basis. Their keen sense of curiosity and reckless ambition are two factors that are so important in the industry we cover and if there is one team that can successfully integrate blockchain technology with the aerospace industry, this is the one.On another note, the work that we are doing is truly cutting-edge. We explore uncharted territories every day with our tech and this brings up a sense of contentment that is hard to describe. I hope that, as a team, we will be able to leave a mark and build something that will truly advance the New Space Economy.Finally, I have always been a bit of an AV Geek, from plane spotting to listening to ATC conversations as a hobby. Having the opportunity to make this my full-time job is a dream come true.You can connect with Alessandra and the rest of our team as well as keep up-to-date with all of SpaceChain’s developments via Twitter and subscribe to our newsletter on our website for our latest news.Moving towards a Decentralised Revolution in Outer Space was originally published in SpaceChain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Space junk: Why it’s everyo...

Estimates by statistical models early last year show that there are over 34,000 debris objects in orbit that are larger than 10cm in size, 900,000 that are between 1cm and 10cm and 128 Million between 1mm and 1cm!Space junk, also called space debris and space garbage, refers to human-made objects in outer space — usually in the Earth orbit — that no longer serve any purpose. These objects typically come from satellites and spent rocket stages as well as the fragments from their disintegration, erosion and collisions. They also include non-functional spacecraft, abandoned launch vehicle stages, mission-related debris and fragmentation debris.With the space industry experiencing exponential growth over the course of the last few decades (coming from the increased number of launches), the amount of junk floating in outer space is enough to draw valid concern from analysts. This figure is touted to total around 8,000 tonnes, made up of thousands of defunct satellites as well as hundreds of thousands of smaller objects that are currently impossible to assess in definite terms due to their minute size.The main concern with an increasing amount of junk floating around in outer space are in the imminent collisions that may occur with existing satellites, causing catastrophic damage. The potential harm that may arise is exacerbated by the fact that these pieces of debris travel at breakneck speeds of over 17,000 mph, which is approximately 10 times the speed of a bullet. To confound matters further, one single crash could create even more debris, causing a much greater chance of more collisions in the future.Image Credit: NASAThe issue of responsibilityThere have been several incidents across the span of the last few decades that have raised eyebrows within the space community, posing questions on the legal responsibilities that nations have when it comes to the creation of space junk. One example of this was China’s 2007 anti-satellite test (ASAT), where it blew up one of its own weather satellites. Aside from causing considerable global military tension, the space industry was also concerned that the mission left behind more than 2,000 new debris elements of trackable size in low-earth orbit.Regulations surrounding the dumping of junk are far hazier in outer space than they are on Earth, with space debris mitigation not being explicitly addressed in the five United Nations (UN) treaties that deal with outer space and related activities across the sphere.That being said, a practical interpretation of the Outer Space Treaty shows that it is the duty of all nations involved in space exploration to do their part to mitigate debris, since it can hinder their right to freely explore and use outer space. The United Nations Committee on the Peaceful Uses of Outer Space also encourages all space participants to refer to its Debris Mitigation Guidelines that provides valuable strategies for the reduction of debris release during normal operations.Image Credit: PixabayJoint tracking efforts between government bodies and private enterpriseEfforts to track space junk have been made on both the government agency as well as private enterprise front.According to their website, NASA’s Orbital Debris Program Office (ODPO) conducts measurements of the orbital environment and implements mitigation measures to protect the users within it. The programme is aimed at creating an improved understanding of the orbital debris environment and measures that can be taken to control debris growth.On the commercial front, companies such as LeoLabs are monitoring up to 250,000 dangerous objects smaller than 10 centimeters (4 inches) wide that orbit Earth. This data will be key in assisting satellite operators and government agencies to avoid catastrophic collisions during their endeavours in outer space.Image Credit: PixabayTechnological advancements to reduce orbital debrisThe space industry has responded appropriately to growing concerns of increased debris floating in outer space, coming out with solutions that promise to solve the issue.The European Space Agency (ESA), commissioned the world’s first space debris removal program in late 2019. The initiative named ClearSpace-1 will help establish a new market for in-orbit servicing, as well as debris removal by launching the world’s first orbiting junk collector, a four-armed robot that tracks down space waste like Pac-Man in a maze, by 2025.A harpoon developed by Airbus Defence and Space in Stevenage, England, has also proven to clean-up orbital traffic lanes, collecting dead satellites and rockets and driving them back into Earth’s atmosphere to burn up.There has also been a myriad of proposed solutions made by private companies to solve space debris issues that could be rolled out over the span of the next several years. One such enterprise has a plan to work with governments and businesses to build a retrieval mechanism within a spacecraft before a launch. If the satellite fails prematurely, an Astroscale spacecraft would launch to intercept the defunct satellite and dispose of it.The issue of space junk is one that SpaceChain is constantly aware of. We strongly advocate for standard practices in dealing with deorbiting satellites and embrace any further advancement in technologies to deal with this problem.As always, you can keep up-to-date with all of SpaceChain’s exciting developments via Twitter.
