[HN Gopher] Launch HN: Turion Space (YC S21) - Space debris remo... ___________________________________________________________________ Launch HN: Turion Space (YC S21) - Space debris removal and satellite servicing Hi HN, we're Ryan, Tyler, and Patryk, the founders of Turion Space (https://www.turionspace.com/). We're building spacecraft to remove orbital debris and provide services to existing satellites. Orbital debris poses a significant risk to mankind's future in space. There are currently over 250k objects in space that would destroy a satellite if a collision were to occur. Large uncontrolled objects like depleted rocket upper stages and dead satellites pose the greatest risk because of the potential to break upon impact with small debris into thousands of smaller pieces. There is currently no system in operation that can deorbit large amounts of space debris. If this problem is not addressed in the next 5-10 years, it could render entire orbits unusable for generations. Our spacecraft (which we've decided to call the "Droid", shoutout to Star Wars!) aims to remove debris by docking with it using robotic arms and dragging the debris to a lower orbit using the ion propulsion system we are developing under a NASA technology transfer license. Once the debris is in a low enough orbit, upper atmospheric drag will cause the debris to naturally decay in altitude until it burns up during atmospheric reentry. Critically, the Droid would undock with the debris after dragging it to a low orbit, then orbit-raise, and go on to perform other missions. In other words, our solution is a reusable approach, designed from the beginning to complete multiple missions during its lifetime. Our team encountered this problem when brainstorming ideas to answer the question, "with the rapidly declining cost of getting things into space, what can we do now that has never before been possible?" Asteroid mining seemed like the obvious answer, but the capital required to start a business on that premise seemed like a longshot to say the least. We found the most important problem we could solve while building the foundation to asteroid resource extraction was to create a satellite system capable of removing orbital space debris. Our team has extensive experience working on operational space flight hardware and building software products from the ground up. Ryan comes from an 8.5-year run at SpaceX, working primarily on propulsion development and dynamics analysis of the Merlin, Superdraco, and Raptor engines. Tyler comes most recently to ATA engineering, working as a consultant for various aspects of thermal, structural, and dynamics analysis across a wide range of now-operational space-flight projects. He also worked at Electroimpact, where he designed and built aerospace-assembly-automation systems using robotic arms. Patryk comes most recently from Marshall Reddick real estate where he developed the company's in house CRM that was vital to the company's growth over the last 5 years. We expect to begin servicing sometime in 2024. We have gained interest in several use cases through conversations with customers to complement our orbital debris removal efforts, beginning with low-earth-orbit operations. For low-earth-orbit satellite operators, we can raise their altitude or modify the inclination of their orbit. We have also partnered with launch providers to expand their mission capabilities by offering our last mile tug service for their payloads. For example, suppose a small launcher can only lift a 200 kg satellite into a 500km orbit altitude, but that payload wishes to end up at a 1200km altitude. In that case, we can dock with the payload once it has been deployed from the launch vehicle and bring it to its final orbit.

We'd love to hear feedback and chat about orbital debris removal!

With higher orbits like GEO | (35,000 km altitude) it actually makes more sense to take | debris and dead satellites out even further to what is known as | the 'graveyard' orbit.

We'll connect with you on LinkedIn. | geenew wrote: | Are there any international law hurdles for this type of | operation?

One situation we will avoid - deorbiting other peoples | things without their permission. Its international waters out | there and if you attempt to dock for example with a Russian | rocket upper stage, (as a US company) that would be an act of | war. No bueno. Lots of regulatory innovation needs to (and we | think will) occur over the next 5-10 years to ensure a | sustainable space environment! | onion2k wrote: | _There is currently no system in operation that can deorbit large | amounts of space debris._ | | If there's some debris in space, who pays to clean it up? Is it a | company that wants to use an orbit that might be affected? Or is | debris attributable and the 'owner' pays to clean up their own | mess? Or is there a fund that a consortium of governments and | businesses that use space should (will?) pay into? | | I can imagine that the tech to do clean up is eminently | achievable, and getting something to orbit to actually do the job | is likely to be cheap enough soon, but I can't quite imagine why | anyone would actually be a customer of a space cleaning company. | paulsutter wrote: | The owner of a satellite under threat from some specific debris | would have a strong incentive to pay.

The business model for orbital debris removal doesn't | really exist at this point. We are starting with a solution | that can provide satellite services and using that to create | a foundation for a economic removal of large space-debris | objects. Once the solution is available with data | demonstrating costs - government bodies will likely come on | board. | cbanek wrote: | As terrible and backward as this sounds, I wonder if who wants | to take the spot next needs to clean up after the first person. | Given the limited number of available slots for certain orbits | like geosync, it might make sense to send something else up to | push the previous satellite out to the dead orbit (if it failed | to get there itself). In this way you're kind of more buying | the "land" and have to demolish the previous house. | ericb wrote: | I think the smart move is to put a regulatory requirement to | either fund removal via a satellite tax, prepayment, or require | a 1-up-1-down trade.

It's a lot like international waters at this | point but there is a very interesting aspect regarding | this. Currently the FCC is the primary governing body in | the space realm and requires all international satellites | to abide by their rules in order to access the US | telecommunications market. This translated to ~90% of all | satellites following their rules due to monetary | incentives. | rwesterdahl wrote: | Right now NO ONE. Crazy right? Well not really. If you forced | people (satellite owners) to pay for someone to deorbit their | stuff, before an affordable service exists, that'd be a quick | way to put a major damper on the booming space economy.

I | was also unsure if the individual needles were still | around, but the article says they'd have decayed after ~3 | years, so it's just those few clumps that are relevant. | jcims wrote: | I've been wondering lately if you could use little puffs of gas | fired from a satellite at very high velocity to impact smaller | debris and take some kinetic energy from it. | | It sounds ridiculous but v^2 scales quickly and if you can | achieve anything close to the exhaust velocity from ion thrusters | combined with retrograde orbit you can start knocking on the door | of 100km/s impact velocity. That's ~5J per microgram. | | Obviously a tremendous number of challenges (puff coherency over | great distances, accuracy over same, stationkeeping, etc) but | interesting to me nonetheless. | rwesterdahl wrote: | Right now we are primarily focused on building something to | address the big stuff because of the possibility of breaking up | into thousands of smaller debris. At some point the smaller | debris will need to be addressed, in which case its possible | something like this would work. That being said Space Lasers | may also be a contender, but that comes with the caveat of | being classified as a weapon. Either way it will be interesting | to see different ideas come to fruition over time, both from | our playbook, and from others! | switch_ wrote: | Lasers were my first thought since it requires so much energy | to change orbits in order to interact more directly with the | debris. What properties are considered when classifying | lasers as weapons? Would a lower power laser still be | feasible for small debris? | erybodyknows wrote: | Interesting problem space and solution. Question, is there any | value in the raw materials contained in the debris? Would it be | feasible to aggregate/collect a certain, let's say, "value | threshold" of debris that makes it economically reasonable to | return a bulk payload back to earth? Even if the answer is | currently "no", it seems like harvesting essentially free | materials and suspending them en masse in a controlled orbit | makes a lot of sense. Eventually groups will want to fabricate in | space, and you could have the raw materials ready to provide. | kartikkumar wrote: | This is quite a popular idea but there's a lot of challenging | economics that haven't been figured out yet. | | CisLunar Industries [1] for example wants to harvest and | process metal from debris on orbit. | | Their initial application is to create metal fuel rods for | thruster technology being developed by Neumann Space [2]. | | [1] https://www.cislunarindustries.com | | [2] https://neumannspace.com | syedkarim wrote: | Who is currently paying for the service of debris removal?

And if nobody will pay to remove stuff, how do you | build a business with that premise? The bridge to reaching that | point for us is utilizing our spacecraft for satellite | servicing at first.

How many worthwhile pieces of debris are in | similar enough orbits that a spacecraft with limited fuel can | even reach both of them? | | ie: if Droid is at a 55 degree inclined orbit, I can't imagine it | could ever reach another object that was at, say, a polar orbit | or an equatorial orbit? | ericbarrett wrote: | One thing I can think of is debris from satellites that | explode, which tends to stay in the same inclination.

Feel free to mess with our services tool | on the website to simulate various missions to see how many | operations a single droid could perform! But to answer your | question, yes, several orbital inclinations are highly | populated with operational satellites and debris. A mission | such as going from 55deg inclination to polar would be possible | but very expensive (ie would likely drain a significant amount | of life out of the Droid on a single mission).

All that being said, | we at Turion Space don't want to build a sustainable future in | space at the cost of polluting Earth.

We would love to chat with you offline, you can message | us your contact information through our website with your email | or email us at info@turionspace.com. | | I'll try to answer these: | | -Fragmentation I'm assuming you are referring to the debris | clouds of small objects after a conjunction. This is a very | hard problem. We are starting with removal of large- | uncontrolled objects before they collide. The solution to | removing those small pieces of debris might be something very | different such as insertion of clouds of inert gas or giant | balloon type sweeps. | | -Initial design is based on orbit modification of operational | satellites then moving to defunct satellites or spent upper | stages.

The possibility of space-based recycling | centers is also exciting. | | -We have talked with Space Force, US department of Space | Commerce, NASA, consultants. One of our advisors on the team is | Kevin O'Connell to help with this. We also joined the group | started by DARPA called CONFERS to work with others in the | industry to develop standards. | | -The timeline has been fairly well modeled by aerospace corp | using monte-carlo simulations. You can find an old version of | this in the "Catcher's Mitt" report. The models will | drastically under-predict the problem if more conjunctions | occur like the Iridium incident, however so it's really hard to | say. The short answer is that ~10 high-risk objects need to be | removed per year to stabilize the issue. ___________________________________________________________________ (page generated 2021-08-04 23:00 UTC) |
