** Obtaining oxygen and metals from lunar regolith: Nearly half of the chemical content of lunar dust is oxygen and most of the rest contains metals, both essential for sustainable lunar settlements. Here is a report from ESA on research into an efficient way to extract these resources from lunar regolith: ESA opens oxygen plant – making air out of moondust – ESA
ESTEC’s oxygen extraction is taking place using a method called molten salt electrolysis, involving placing regolith in a metal basket with molten calcium chloride salt to serve as an electrolyte, heated to 950°C. At this temperature the regolith remains solid.
But passing a current through it causes the oxygen to be extracted from the regolith and migrate across the salt to be collected at an anode. As a bonus this process also converts the regolith into usable metal alloys.
In fact this molten salt electrolysis method was developed by UK company Metalysis for commercial metal and alloy production. Beth’s PhD involved working at the company to study the process before recreating it at ESTEC.
On the left side of this before and after image is a pile of simulated lunar soil, or regolith; on the right is the same pile after essentially all the oxygen has been extracted from it, leaving a mixture of metal alloys. Both the oxygen and metal could be used in future by settlers on the Moon. Samples returned from the lunar surface confirm that lunar regolith is made up of 40-45% percent oxygen by weight, its single most abundant element. Credits: ESA
“At Metalysis, oxygen produced by the process is an unwanted by-product and is instead released as carbon dioxide and carbon monoxide, which means the reactors are not designed to withstand oxygen gas itself,” explains Beth. “So we had to redesign the ESTEC version to be able to have the oxygen available to measure. The lab team was very helpful in getting it installed and operating safely.”
The oxygen plant runs silently, with the oxygen produced in the process is vented into an exhaust pipe for now, but will be stored after future upgrades of the system.
“The production process leaves behind a tangle of different metals,” adds Alexandre, “and this is another useful line of research, to see what are the most useful alloys that could be produced from them, and what kind of applications could they be put to.
The use of lava tubes on Mars as emergency shelters and storage has been advanced by researchers at the Antarctic Institute of Canada.
Lava tubes are formed from fast moving lava which later cools and forms roomy caves that might serve various functions for future human expeditions to the Red Planet.
Svetozar Zirnov, Daniel Polo, and Austin Mardon of the institute floated the idea at this week’s Seventh International Conference on Mars Polar Science and Exploration being held in Ushuaia, Tierra del Fuego, Argentina.
Science fiction often imagines our future on Mars and other planets as run by machines, with metallic cities and flying cars rising above dunes of red sand. But the reality may be even stranger – and “greener.” Instead of habitats made of metal and glass, NASA is exploring technologies that could grow structures out of fungi to become our future homes in the stars, and perhaps lead to more sustainable ways of living on Earth as well.
The myco-architecture project out of NASA’s Ames Research Center in California’s Silicon Valley is prototyping technologies that could “grow” habitats on the Moon, Mars and beyond out of life – specifically, fungi and the unseen underground threads that make up the main part of the fungus, known as mycelia.
“Right now, traditional habitat designs for Mars are like a turtle — carrying our homes with us on our backs – a reliable plan, but with huge energy costs,” said Lynn Rothschild, the principal investigator on the early-stage project. “Instead, we can harness mycelia to grow these habitats ourselves when we get there.”
Ultimately, the project envisions a future where human explorers can bring a compact habitat built out of a lightweight material with dormant fungi that will last on long journeys to places like Mars. Upon arrival, by unfolding that basic structure and simply adding water, the fungi will be able to grow around that framework into a fully functional human habitat – all while being safely contained within the habitat to avoid contaminating the Martian environment.
This video from the NIAC 2018 Symposium includes a presentation about the fungi construction starting at around the 1:25:00 point:
We propose a public/private partnership to develop and demonstrate space solar power at a sufficiently high technical level that commercial energy providers can subsequently build operational systems for high-energy-cost environments such as remote mining facilities. The outlines of the partnership are based on the successful Commercial Orbital Transportation Services program that helped develop the SpaceX Falcon 9 launcher/Dragon capsule and the Orbital Sciences Corp. Antares launcher and Cygnus spacecraft. The Space Solar Power Demo development described here features minimal NASA oversight, milestone-driven fixed-price payouts, minimal exit criteria, substantial commercial partner funding commitments, non-traditional contracts (e.g., Space Act Agreements with NASA), commercial partner choice of energy market and energy consumer, enabling system development (e.g., space robotics), and at least two winners.

** Space X set to launch Falcon 9 with 60 more Starlink satellites this week but the launch day depends on the weather conditions at both the Cape and the area in the Atlantic where the booster will land. Keeping launch costs as low as possible is crucial for the economic viability of the Starlink enterprise, which will involve launching thousands of satellites. And that means recovering and reusing the boosters is very important. Today, SpaceX said they were now targeting Monday for liftoff:
Weather in the recovery area continues to be unfavorable so team is now targeting Monday, January 27 for launch of Starlink, pending Range availability
The on-pad test firing of the engines took place successfully last Monday:
Static fire of Falcon 9 complete ahead of launching 60 Starlink satellites. Due to extreme weather in the recovery area, team is evaluating best launch opportunity
Rocket Lab has announced its first mission of 2020 – a dedicated launch for the National Reconnaissance Office (NRO). Their workhorse Electron rocket, launching from Launch Complex 1 in New Zealand, will loft the classified NROL-151 satellite to an unknown orbit. The mission was awarded by the NRO as part of their Rapid Acquisition of a Small Rocket (RASR) program, with the goal of increasing the amount of small-lift launch providers they can choose from.
…
This mission will be Rocket Lab’s first launch for the NRO. The mission was nicknamed “Birds of a Feather”, likely referencing the Kiwi and Eagle, the national birds of the two involved countries.
Due to the classified nature of this launch, very few details have been made public. NROL-151’s purpose, orbit, size, and other specifications are unknown.
Officials later clarified that no explosion occurred. Tom Markusic, Firefly’s CEO, told KXAN — the NBC television affiliate in Austin — that a fuel leak resulted in a small fire on the test stand.
Firefly was gearing up for the first in a series of full-scale first stage hotfire tests on a vertical stand in Briggs. The first stage of Firefly’s Alpha launcher, which the company previously said could be ready for a first flight this spring, is powered by four Firefly-built Reaver engines consuming kerosene and liquid oxygen propellants.
The company said Dec. 30 that qualification testing of the Alpha launcher’s first stage had started. The first stage is the last major piece of Firefly’s privately-developed launcher to undergo qualification testing, and the test campaign was expected to include multiple test-firings.
Yesterday evening we attempted to hotfire test the Alpha first stage for the first time. Unfortunately, after the four Reaver engines ignited, an engine bay fire developed (flame jet to the left in video). The system immediately shut itself down and the fire was quickly pic.twitter.com/YGYcEshrd9

And from Boeing: “Following a detailed review, Boeing is ending our role in the Experimental Spaceplane (XSP) program immediately. We will now redirect our investment from XSP to other Boeing programs that span the sea, air and space domains.”
Boeing statement: “Following a detailed review, Boeing is ending our role in the Experimental Spaceplane (XSP) program immediately. We will now redirect our investment from XSP to other Boeing programs that span the sea, air and space domains.”
Boeing won the competition over teams led by Northrop Grumman Aerospace Systems and Masten Space Systems to build a rocket vehicle with a reusable first stage that could put 3000 lbs (1360) into low earth orbit and be prepared for another flight in a short time. The key program goal was to demonstrate that the vehicle could fly everyday for ten straight days. It would then be up to Boeing to continue to offer the vehicle for operational satellite launch missions.

The USAF procurement establishment has tried to bring in smaller companies like Masten to compete with the big legacy aerospace behemoths on this sort of modest sized technology project. And sometimes a small firm actually makes it to the second phase in the process. However, the legacy giant still almost always wins the final round since it gets the check-boxes marked for greatest depth of engineering talent, experience, and resources. Unfortunately, this ignores the fact that the project will be assigned a low priority by the giant. The opposite is true for the small company, which most likely needs the project to succeed if it is to stay in business.
As Stratolaunch ramps up operations after being sold last year, it says it remains interested in providing launch services as well as supporting hypersonic vehicles.
In a Jan. 21 statement to SpaceNews, Stratolaunch spokesperson Art Pettigrue confirmed the company was interested in “reliable, routine access to space” while also confirming the company was interested in hypersonics research.
“Stratolaunch is exploring the development of aerospace vehicles and technologies, including the need for reliable, routine access to space,” Pettigrue said. “This exploration includes the need to significantly advance the nation’s ability to design and operate hypersonic vehicles.”
Dawn Aerospace is commercializing thrusters that use nitrous oxide and propene instead of hydrazine. Its 5-pound-force thruster is produced without components restricted by U.S. International Traffic in Arms Regulations, according to the company.
Wink said Dawn Aerospace built three flight-ready propulsion systems for cubesats in 2019, and eight larger thrusters for microsatellites. This year the company aims to build 50 cubesat thrusters and 100 microsat thrusters, he said.
Dawn Aerospace is using revenues from those sales to develop a drone-launched rocket system. Rea said the uncrewed spaceplane would fly above 100 kilometers, reaching a speed of 4-kilometers per second. An expendable two-stage rocket would then vault “several hundred kilograms” into low Earth orbit, Wink said.
A NASA press release following the test discussed investigations into the timing issue that led to the failure to rendezvous with the ISS and into whether another uncrewed test flight was needed. The release
… did not mention thruster performance, but an agency source told Ars that engineers are looking closely at the performance of the Starliner propulsion system. In addition to four large launch abort engines, the service module has 28 reaction control system thrusters, each with 85 pounds of thrust and 20 more-powerful orbital maneuvering thrusters, each with 1,500 pounds of thrust.
During the post-flight news conference Jim Chilton, Boeing’s senior vice president of the Space and Launch division, said the service module thrusters were stressed due to their unconventional use in raising Starliner’s orbit instead of performing one big burn. As a result, the company had to shut down one manifold, which effectively branches into several lines carrying propellant to four thrusters. “We even shut down one manifold as we saw pressure go low ’cause it had been used a lot,” he said.
The NASA source said eight or more thrusters on the service module failed at one point and that one thruster never fired at all.
In response to a question about thruster performance, Boeing provided the following statement to Ars: “After the anomaly, many of the elements of the propulsion system were overstressed, with some thrusters exceeding the planned number of burns for a service module mission. We took a few cautionary measures to make sure the propulsion system stayed healthy for the remainder of the mission, including re-pressurizing the manifold, recovering that manifold’s thrusters. Over the course of the mission we turned off 13 thrusters and turned all but one back on after verifying their health.”
UP expects to reach another milestone in February, when it conducts static ground tests on four different solid-propellant rocket motors it’s built at the spaceport to propel a new, four-stage, satellite-carrying rocket called the Spyder into low earth orbit, Larson said. Up has been developing Spyder for about five years in cooperation with NASA to offer a reusable, low-cost alternative to rapidly launch satellites.
“It will be a huge milestone for us when we static test all four motors,” Larson said. “We’ll lock up the technology and work out all the bugs.”
The orbital Spyder system won’t fly from the spaceport, because with four stages, some of the boosters could fall back to earth over potentially inhabited areas, Larson said. Rather, it will fly from the Mid-Atlantic Regional Spaceport on Virginia’s Wallops Island, where depleted stages can fall into the ocean.
But UP is also developing a suborbital version of the Spyder that will fly from the spaceport.
In the 1990s, NASA identified three critical technology needed to make an SSTO spacecraft achievable:
(1) advanced composite materials;
(2) altitude compensating engines; and
(3) tri-propellant engines.
The required advanced composites materials have largely been developed over the past 25 years, as witness the improved aluminum alloys and more advanced carbon composites now available. The altitude-compensating engines are needed to so that one engine can both take off in the atmosphere and make orbit in a vacuum. NASA made progress on this with the one-third scale Lockheed Martin X-33 and the Air Force Research Laboratory (AFRL) is currently investigating aerospike nozzles with the Affordable Responsive Modular Rocket (ARMR) Program. What has been lacking is the tri-propellant propulsion technology for SSTO-RLVs.
Entrepreneurial firms, such as TGV, have proposed novel approaches to the challenges of an SSTO-RLV. These innovations include new ways of approaching a tri-propellant engine, novel engine nozzles for altitude compensation, and new launch sites for more flexibility. Engineering for reliability, deep throttling, landing, and imaginative systems engineering are currently needed to improve the mass fraction and operability of a practical SSTO-RLV. These technologies are ready to be developed and brought into routine use in a reasonable time frame.
**** Crew Dragon spacecraft successfully escaped from a failing Falcon 9 booster shortly after launch from Pad 39A at KSC last Sunday. The in-flight abort (IFA) demonstration was the final major test flight before a Crew Dragon can carry astronauts to the ISS. There remain a couple of tests of the complete parachute system plus lots of reviews of IFA data, spacecraft and launcher systems, etc. The earliest that a Dragon will take a crew to the Station is late March but it might slip to late June.
Some videos of the IFA test:

**** SpaceX may eventually try to catch a Crew Dragon with a net as they are currently trying to perfect for the fairings during satellite launches:
Elon wants to catch Dragon with the fairing catching ships to keep them out of the water. Mentions that they need to talk to NASA about that first and that fairing recovery needs to get more reliable first. #SpaceX
This is not the first time Musk has mentioned such a plan. Back in February 2018, he noted that SpaceX ship Mr. Steven (now Ms. Tree), designed to catch parasailing fairing halves out of the air, “might be able to do the same thing with Dragon — if NASA wants us to, we can try to catch Dragon.” The motivation behind catching Dragon – instead of fishing it out of the Atlantic Ocean – is effectively the same reason that SpaceX is trying to routinely catch Falcon fairings: it’s much easier to reuse aerospace hardware that hasn’t been dunked and soaked in saltwater.
Of course, Musk cautioned that SpaceX would only pursue Dragon catches if NASA were open to the idea – the space agency’s conservatism is already largely responsible for the death of propulsive Crew Dragon landing, also intended to make spacecraft reuse much easier. Additionally, the CEO qualified his comments by noting that SpaceX would attempt to catch Crew Dragon only after Falcon fairing halves are being routinely and reliably caught.
**** Starship
****** Elon Musk comments on Starship plans during informal session with media following NASA’s press briefing on the abort test.
Items of interest:
Planned to fly later that day to Boca Chica to work with the team there.
Expects there to be a lengthy period of overlap with Starship, Falcon 9, Crew Dragon, and Falcon Heavy all operating.
Each has incorporated improvements and expects these to continue up through SN-50
Structure development going more slowly. Will focus on that while at Boca Chica.
The tank domes might seem a trivial issue but attaching them such that they can withstand the required pressures is a terrifically difficult problem.
Listed various other structure items including the interfaces between the tanks, landing legs, heat shield, etc.
Orbital propellant refilling is a crucial capability and very difficult. Precision rendezvous and docking of two Starships is similar to docking two big space stations.

****** A place to build starships away from the weather:
SpaceX’s South Texas team of Starship engineers and technicians – including CEO Elon Musk himself – are working around the clock to manufacture hardware that will likely become the company’s next Starship prototype in the near future.
Over the last few days, SpaceX has made quick progress churning out shiny steel rings and wrapping up propellant tank domes – the next round of full-scale Starship hardware. To better build the first flight and orbit-capable prototypes, not to mention hundreds or even thousands of Starship spacecraft and Super Heavy boosters in the years to come, SpaceX teams and contractors have spent the last two months aggressively expanding the company’s Boca Chica, Texas facilities. In fact, the very same company that built Tesla’s newest tent-based Model 3 assembly line – Sprung Instant Structures – has erected part of a massive, new Starship factory.

**Rick Fleeter – A Personal History of Smallsats – The Cold Star Project S02E04
Dr. Rick Fleeter, associate adjunct professor at Brown University and visiting lecturer at La Sapienza (Rome), has decades of personal history with small satellites.
“I got started in microspace through amateur radio and AMSAT. In the early 1980s I had the unusual experience of spending evenings building small satellites in a garage in Redondo Beach, CA, paid for essentially with small contributions by the team that was building them, while during the day working at the Jet Propulsion Laboratory and then TRW, where it was insisted that without something close to $1 billion there wasn’t much you could do other than paper studies.”
Rick Fleeter was launching smallsats in the 1970s, when they were considered merely a hobby or toys. Since then he has helped change the perception of cubesats to useful tools by leading well designed, cost-minimized projects. As an example, Brown’s Space Engineering department built a satellite for just $5000. He has written books, founded the company AeroAstro and the Space Horizons annual conference at Brown.
