** What if the ISS was retired early? – Laura Forczyk

Elon Musk is calling for the International Space Station to be deorbited earlier than the currently planned 2030, even as early as 2027. How would that work with SpaceX’s US Deorbit Vehicle and NASA’s international partners? What would happen with the ongoing microgravity research?

None of the commercial space stations will be ready in time for long-term habitation, and alternatives ideas such as using Starship as a space station aren’t guaranteed to happen in time, either. How much would China benefit from having the Tiangong, the only low-Earth orbit destination? Congress is going to push back on any proposal by the Trump Administration to “abandon LEO” in favor of sending astronauts to Mars, but how this plays out is to be seen.

** Axiom Space

— Axiom and Red Hat to demonstrate orbital data center on the ISS in 2025: Red Hat Teams Up with Axiom Space to Launch, Optimize the Space Company’s Data Center Unit-1 On Orbit | Red Hat – Mar.6.2025

Red Hat, Inc., the world’s leading provider of open source solutions and Axiom Space, leading provider of in-space infrastructure, will collaborate on Axiom Space’s Data Center Unit-1 (AxDCU-1), targeted to launch in spring 2025 to the International Space Station. Powered by Red Hat Device Edge, the data processing prototype will conduct tests on the space station and demonstrate initial Orbital Data Center (ODC) capabilities. 

The prototype will test applications in cloud computing, artificial intelligence and machine learning (AI/ML), data fusion and space cybersecurity. AxDCU-1 is part of Axiom Space’s ongoing work to develop era-defining space infrastructure.

Red Hat Device Edge combines an enterprise-ready and supported distribution of the Red Hat-led open source community project MicroShift, a lightweight Kubernetes distribution derived from the edge capabilities of Red Hat OpenShift, along with Red Hat Enterprise Linux and Red Hat Ansible Automation Platform. Red Hat Device Edge will enable Axiom Space to host hybrid cloud applications and cloud-native workloads on-orbit. 

Axiom Space’s ODCs are designed to bring tangible benefits to humanity on Earth and reduce delays traditionally associated with orbital data processing and analysis. By utilizing Earth-independent cloud storage and edge processing infrastructure, Axiom Space ODCs will enable data to be processed closer to its source, spacecraft or satellites, bypassing the need for terrestrial-based data centers. This architecture alleviates reliance on costly, slow, intermittent or contested network connections, creating more secure and quicker decision-making in space.

The goal is to allow Axiom Space and its partners to have access to real-time processing capabilities, laying the foundation for increased reliability and improved space cybersecurity with extensive applications. Use cases for ODCs include but are not limited to supporting Earth observation satellites with in-space and lower latency data storage and processing, AI/ML training on-orbit, multi-factor authentication and cyber intrusion detection and response, supervised autonomy, in-situ space weather analytics and off-planet backup & disaster recovery for critical infrastructure on Earth.

— Construction underway for flight version of the Haven-1 single-module space station:

— NASASpaceFlight visits Vast and reports on the progress of their space station program: Vast space station qualification article passes major milestone | NASASpaceFlight.com – Feb,11,2025

Vast is one step closer to launching its first private commercial space station. The company recently completed testing of its Haven-1 qualification article in Mojave, California, and reported that it successfully passed its tests. The company’s current goal is to launch the flight article aboard a SpaceX Falcon 9 rocket no earlier than May 2026.

During a tour of Vast’s facilities in Long Beach, California, with NSF’s John Galloway and D Wise, Vast gave insights into their plans to eventually win a NASA contract to allow their larger space station, Haven-2, to act as a replacement following the deorbiting of the International Space Station (ISS), which is currently scheduled for 2030.

“None of us are actual space station companies,” Vast CEO Max Haot said. “I don’t have a space station in orbit. I cannot have a crew go to it and come back. Neither have any of our competitors… so if we want to create this amazing future, we need to exist. To exist, we need to be profitable. So, to be profitable, we believe we need NASA as an anchor customer.”

ESO: First 3D observations of an exoplanet’s atmosphere

A new report from the European Southern Observatory (ESO)

“Out of science fiction”: First 3D observations
of an exoplanet’s atmosphere reveal a unique climate

Tylos (or WASP-121b) is a gaseous, giant exoplanet located some 900 light-years away in the constellation Puppis. Using the ESPRESSO instrument on ESO’s Very Large Telescope (VLT), scientists have been able to prove into its atmosphere, revealing its 3D structure. This is the first time that this has been possible on a planet outside of the Solar System.  The atmosphere of Tylos is divided into three layers, with iron winds at the bottom, followed by a very fast jet stream of sodium, and finally an upper layer of hydrogen winds. This kind of climate has never been seen before on any planet.

Astronomers have peered through the atmosphere of a planet beyond the Solar System, mapping its 3D structure for the first time. By combining all four telescope units of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), they found powerful winds carrying chemical elements like iron and titanium, creating intricate weather patterns across the planet’s atmosphere. The discovery opens the door for detailed studies of the chemical makeup and weather of other alien worlds.

“This planet’s atmosphere behaves in ways that challenge our understanding of how weather works — not just on Earth, but on all planets. It feels like something out of science fiction,”

says Julia Victoria Seidel, a researcher at the European Southern Observatory (ESO) in Chile and lead author of the study, published today in Nature.

The planet, WASP-121b (also known as Tylos), is some 900 light-years away in the constellation Puppis. It’s an ultra-hot Jupiter, a gas giant orbiting its host star so closely that a year there lasts only about 30 Earth hours. Moreover, one side of the planet is scorching, as it is always facing the star, while the other side is much cooler.

The team has now probed deep inside Tylos’s atmosphere and revealed distinct winds in separate layers, forming a map of the atmosphere’s 3D structure. It’s the first time astronomers have been able to study the atmosphere of a planet outside our Solar System in such depth and detail.

“What we found was surprising: a jet stream rotates material around the planet’s equator, while a separate flow at lower levels of the atmosphere moves gas from the hot side to the cooler side. This kind of climate has never been seen before on any planet,”

says Seidel, who is also a researcher at the Lagrange Laboratory, part of the Observatoire de la Côte d’Azur, in France. The observed jet stream spans half of the planet, gaining speed and violently churning the atmosphere high up in the sky as it crosses the hot side of Tylos.

“Even the strongest hurricanes in the Solar System seem calm in comparison,”

she adds.

This diagram shows the structure and motion of the atmosphere of the exoplanet Tylos (WASP-121b). The exoplanet is shown from above in this figure, looking at one of its poles. The planet rotates counter-clockwise, in such a way that it always shows the same side to its parent star, so it’s always day on one half of the planet and night on the other. The transition between night and day is the “morning side” while the “evening side” represents the transition between day and night; its morning side is to the right and its evening side to the left. As the planet crosses in front of its host star, atoms in the planet’s atmosphere absorb specific colours or wavelengths of the star’s light, which can be measured with a spectrograph. From this data –– obtained in this case with the ESPRESSO instrument on ESO’s Very Large Telescope –– astronomers can reconstruct the composition and velocity of different layers in the atmosphere. The deepest layer is a wind of iron that blows away from the point of the planet where the star is directly overhead. Above this layer there is a very fast jet of sodium that moves faster than the planet rotates. This jet actually accelerates as it moves from the morning side to the evening side of the planet. Finally, there is an upper layer of hydrogen wind blowing outwards. This hydrogen layer overlaps with the sodium jet below it.

To uncover the 3D structure of the exoplanet’s atmosphere, the team used the ESPRESSO instrument on ESO’s VLT to combine the light of its four large telescope units into a single signal. This combined mode of the VLT collects four times as much light as an individual telescope unit, revealing fainter details. By observing the planet for one full transit in front of its host star, ESPRESSO was able to detect signatures of multiple chemical elements, probing different layers of the atmosphere as a result.

“The VLT enabled us to probe three different layers of the exoplanet’s atmosphere in one fell swoop,”

says study co-author Leonardo A. dos Santos, an assistant astronomer at the Space Telescope Science Institute in Baltimore, United States. The team tracked the movements of iron, sodium and hydrogen, which allowed them to trace winds in the deep, mid and shallow layers of the planet’s atmosphere, respectively.

“It’s the kind of observation that is very challenging to do with space telescopes, highlighting the importance of ground-based observations of exoplanets,”

he adds.

Interestingly, the observations also revealed the presence of titanium just below the jet stream, as highlighted in a companion study published in Astronomy and Astrophysics. This was another surprise since previous observations of the planet had shown this element to be absent, possibly because it’s hidden deep in the atmosphere.

“It’s truly mind-blowing that we’re able to study details like the chemical makeup and weather patterns of a planet at such a vast distance,”

says Bibiana Prinoth, a PhD student at Lund University, Sweden, and ESO, who led the companion study and is a co-author of the Nature paper.

To uncover the atmosphere of smaller, Earth-like planets, though, larger telescopes will be needed. They will include ESO’s Extremely Large Telescope (ELT), which is currently under construction in Chile’s Atacama Desert, and its ANDES instrument.

“The ELT will be a game-changer for studying exoplanet atmospheres,” says Prinoth. “This experience makes me feel like we’re on the verge of uncovering incredible things we can only dream about now.”

The mission flew on a Falcon 9, spot-welded together some quarter-inch pieces of aluminum, and returned it to Earth, where the welds were closely examined.

They used a method called electron beam welding, which has several advantages for use in space. First, it doesn’t require as much power as a traditional arc welder—only around 2KW, equivalent to a household iron. Second, it doesn’t create a lot of heat, which can degrade the metal being welded and cause issues like splintering, which can become dangerous in zero-gravity situations.

** Overview article about rotating habitats to simulate gravity: A potpourri of artificial gravity topics | Space Settlement Progress – Jan.29.2025

In this month’s post we explore a few concepts and challenges related to artificial gravity (AG) that when explored and understood will enable human’s to live healthy lives and thrive in space. First up, Austria-based architect and civil engineer Werner Grandl, a researcher of space stations and space colonies, and mechanical engineer Clemens Böck describe their concept for the evolving construction of a spinning Artificial Gravity Orbital Station (AGOS) in this Research Gate working paper. AGOS is envisioned as a potential successor to the International Space Station (ISS).

** How NASA Plans to Revolutionize Lunar Excavation – NASA’s Kennedy Space Center

How does NASA plan to use resources on the surface of the Moon?

One method is the ISRU Pilot Excavator, or IPEx!

Designed by Kennedy Space Center’s Swamp Works team, the primary goal of IPEx is to dig up lunar soil, known as regolith, and transport it across the Moon’s surface.

** Derek Webber on The Space Show – Jan.24.2025 – Lunar Commerce, Moon vs Mars, etc

Derek Webber returned to the program to discuss his excellent new book, “Lunar Commerce: A Primer [Amazon commission link].” During the hour and 45 minutes we engaged in a detailed discussion about lunar commerce from what we can do now to a long time in the future. Part of this discussion centered on going to Mars, the Moon as a digression, then new Trump Administration lunar and/or Mars policy, cislunar, launchers, Elon Musk, Jeff Bezos and so much more. We had several listener calls plus multiple emails with a few listeners sending us multiple emails as extensions of their first one. Derek’s book names companies, policies, all sorts of good items are jam packed into the nearly 200 pages jammed pack with excellent information.

=== Mars habitation

** “A science-driven program that could get astronauts on the Red Planet by 2031”: The Mars Dream Is Back — Here’s How to Make It Actually Happen | Robert Zubrin/The New Atlantis – Spring 2025

America now has a once-in-a-generation opportunity to open the space frontier by initiating a sustained program of human exploration of Mars. Elon Musk’s SpaceX Starship launch system will soon be operational, offering payload delivery capability comparable to a Saturn V Moon rocket at about five percent of the cost. Musk has positioned himself close to President Donald Trump, who at his inauguration in January promised that his administration would be “launching American astronauts to plant the Stars and Stripes on the planet Mars.” As far as meeting the central political and technical conditions for making a bold reach to the Red Planet are concerned, it’s game on.

There are, however, several problems. First and foremost, the National Aeronautics and Space Administration, the government agency that one would expect to lead such an endeavor, is currently not competent to do so. And while SpaceX is far more competent, it should not be put into the position of executing a Mars mission alone, as some would like. NASA needs to be leading the effort because America should go to Mars, not just a private space enterprise. But to effectively lead human space exploration, NASA first needs to be fixed.

=== Space settlement

** Broadcast 4325 JOHN JOSSY, Space Settlement 2025 | The Space Show

We welcomed John Jossy back to the show, especially at the last minute when the planned guest cancelled due to illness. John brought us current on space settlement matters as we start the new year with a new administration. Our topics in the mentioning of a new space film documentary, the Gerald Black Space Review article on phasing out SLS and Orion, Starship impact, the new Dr. Joel Sercel of TransAstraYouTube video on creating civilizations in space, plus John’s own list of special items including links to the relative subjects and materials. John also posted a short agenda items list of his discussion point on the blog for this program.

=== Earth views from ISS

** Night Lights and Aurora – UCTVInsight

Enjoy the creativity of astronaut Don Pettit, currently on his 4th mission aboard the ISS, as he captures surreal photos of Earth. His long-duration exposures reveal tracks of urban night lights as the ISS passes over. The stars show their own curving pattern, and the aurora adds even more mystery. This magical dance is accompanied by the music of Chilean composer Mario Quiroga. He is a “musico-terapista” (musical therapist), who creates floating music with his digital synthesizers, designed to help soothe the soul. Here we feature his “Aurora Boreal” composition, like a musical magic carpet as we soar over these ethereal views. Recorded on 11/9/2024. 

** Live Video from the International Space Station (Official NASA Stream) – NASA

Watch live video from the International Space Station, including inside views when the crew aboard the space station is on duty. Views of Earth are also streamed from an external camera located outside of the space station. During periods of signal loss due to handover between communications satellites, a blue screen is displayed.

The space station orbits Earth about 250 miles (425 kilometers) above the surface. An international partnership of five space agencies from 15 countries operates the station, and it has been continuously occupied since November 2000. It’s a microgravity laboratory where science, research, and human innovation make way for new technologies and research breakthroughs not possible on Earth. More: https://go.nasa.gov/3CkVtC8

Did you know you can spot the station without a telescope? It looks like a fast-moving star, but you have to know when to look up. Sign up for text messages or email alerts to let you know when (and where) to spot the station and wave to the crew: https://spotthestation.nasa.gov
