Here is the latest episode in NASA’s Space to Ground weekly report on activities related to the International Space Station:

** Christina Koch’s Memorable Moments: Part 4

The longest-ever single spaceflight by a female astronaut is now 322 days long, and still counting! Today NASA astronaut Christina Koch moved past her colleague Suni Williams into seventh place for most time spent in space among all American astronauts. With less than a week to go, Koch recalls the biggest surprise of the mission and the most memorable item she received on a cargo flight.

** Down to Earth – Black Velvet of Space

In honor of the space station 20th anniversary, NASA Astronaut Bill McArthur shares his experience living and working in space aboard the International Space Station in this episode of “Down to Earth – Black Velvet of Space.” As he describes it, he experienced a shift in his worldview known as “the Overview Effect,” a term coined by space philosopher Frank White.

Space settlement roundup – Jan.26.2020

A sampling of recent articles, videos, and images related to human expansion into the solar system (see also previous space settlement postings):

** 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.

** Mars caves as shelters: More about the utility for settlement of lava tubes on Mars:  Mars Lava Tubes: Emergency Shelter and Storage – Leonard David

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.

** Growing shelters on Mars with mushrooms: Could Future Homes on the Moon and Mars Be Made of Fungi? | NASA

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:

** A COTS model for space-based solar power: A Public/Private Program to Develop Space Solar Power, Al Globus and John C. Mankins, January 2020.

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.

LEGO offers new International Space Station kit

LEGO will release the International Space Station kit on February 1st. The highly elaborate kit (list price $69.99) is in the IDEAS line of models “inspired and voted for by LEGO fans”:

Packed with authentic ISS details, including a posable Canadarm2 and 2 rotating joints that coincide with 8 adjustable ‘solar panels’, this 864-piece set is a wonderful gift idea for space enthusiasts, adult LEGO fans or any experienced builder. Beautiful centerpiece This awesome LEGO spaceship model comes with a display stand, a buildable mini NASA space shuttle and 3 mini cargo spacecrafts, plus 2 astronaut microfigures to create a striking centerpiece in any room. Illustrated instructions are included, plus a 148-page booklet with fascinating ISS facts and information about the LEGO fan who created this space model kit and its LEGO designer [Christophe Ruge].

The LEGO International Space Station model kit.

The announcement on Twitter:

A skilled builder shows how it’s done”

collectSPACE says:

LEGO first announced that it was producing the International Space Station as a toy set in June 2019, after it won a fan poll in celebration of the 10th anniversary of the LEGO Ideas website. The space station received 45 percent of the more than 22,000 votes cast in a competition against three other possible sets.

The LEGO ISS got its start five years earlier, when Christoph Ruge, a LEGO and space enthusiast from Germany, first submitted his design for the space station brick-built model to the LEGO Ideas website. It qualified for a review by the LEGO team, but was rejected in 2015.

In 2018, Ruge re-entered his space station after scaling it down to match the size of the shuttle included in a winning LEGO Ideas project, the “Women of NASA” set released in 2017. (The orbiter included in the ISS set coming out Feb. 1 is similar to, but not identical to the “Women of NASA” model.) Again, LEGO’s design team did not select Ruge’s ISS to go forward, but then the anniversary vote came about.

The complete LEGO ISS kit.
