Tohoku University: Biomolecules from Formaldehyde on Ancient Mars

Organic materials discovered on Mars may have originated from atmospheric formaldehyde, according to new research, marking a step forward in our understanding of the possibility of past life on the Red Planet. Scientists from Tohoku University have investigated whether the early atmospheric conditions on Mars had the potential to foster the formation of biomolecules – organic compounds essential for biological processes. Their findings, published in Scientific Reports, offer intriguing insights into the plausibility of Mars harboring life in its distant past.

University of Cambridge: Astronomers Spot Oldest “Dead” Galaxy Yet Observed

A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, an international team of astronomers led by the University of Cambridge has spotted a ‘dead’ galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed. This galaxy appears to have lived fast and died young: star formation happened quickly and stopped almost as quickly, which is unexpected for so early in the universe’s evolution. However, it is unclear whether this galaxy’s ‘quenched’ state is temporary or permanent, and what caused it to stop forming new stars.

Webbtelescope.org: Webb Unlocks Secrets of One of the Most Distant Galaxies Ever Seen

Delivering on its promise to transform our understanding of the early universe, the James Webb Space Telescope is probing galaxies near the dawn of time. One of these is the exceptionally luminous galaxy GN-z11, which existed when the universe was just a tiny fraction of its current age. One of the youngest and most distant galaxies ever observed, it is also one of the most enigmatic. Why is it so bright? Webb appears to have found the answer. Scientists using Webb to study GN-z11 have also uncovered some tantalizing evidence for the existence of Population III stars nestled in the outskirts of this remote galaxy. These elusive stars — the first to bring light to the universe — are purely made of hydrogen and helium. No definitive detection of such stars has ever been made, but scientists know they must exist. Now, with Webb, their discovery seems closer than ever before.

Space Stories: DART Damage, India Plans for Orbiting Crew, and SLIM Awakes on the Moon

NDTV: NASA’s Mission Not Only Altered Asteroid’s Path, But Its Shape Too, Says New Study

A recent study suggests NASA’s DART mission, designed to test asteroid deflection methods, may have revealed more than planned. While successfully altering the target asteroid’s trajectory, scientists now believe the impact also significantly changed its shape, hinting at a surprising composition. Previously thought to be a solid rock, Dimorphos, the impacted asteroid, may actually be a loose collection of debris. This conclusion stems from the unexpected level of deformation observed after the collision. Unlike a typical crater, the impact appears to have caused a broader, flatter dent, resembling an M&M candy.

Reuters: India Announces Four-member Crew for ‘Gaganyaan’ Space Mission

India on Tuesday introduced four crew members for its maiden ‘Gaganyaan’ space voyage, as it aims to become the world’s fourth country to send a crewed mission into space just months after a historic landing on the south pole of the moon. Gaganyaan, or “sky craft” in Hindi, is the first mission of its kind for India and will cost about 90.23 billion rupees ($1.1 billion). It involves the launch of a habitable space capsule over the next year to an orbit of 400 km (250 miles) and its return via a landing in the Indian Ocean.

SpaceNews.com: “Japan’s SLIM Moon Lander Stages Unexpected Revival After Lunar Night

Japan’s space agency made contact with its SLIM moon lander Sunday, despite the spacecraft not being expected to function after lunar night. Contact with the Smart Lander for Investigating Moon (SLIM) spacecraft was reestablished on Sunday, Feb. 25, the Japan Aerospace Exploration Agency (JAXA) announced via its dedicated SLIM account on X, formerly known as Twitter, early Feb. 26.

Look Up: Is That Magnolia Wood?

The satellite industry may never be the same again. While we hear so much about new metals in our rockets, how often do you hear of simply putting wood into orbit?

I guess we should not have been too surprised now that wood is being used to build office towers. And the best part is that wooden satellites burn cleaner than metal satellites, making them safer for the environment.

Last year we learned about the Kyoto University’s test of wood materials on the International Space Station. The findings indicated that magnolia wood was one of the better materials for spacecraft, though more testing was needed.

The plan is for a summer 2024 launch of a coffee-size probe called LignoSat that can then be monitored for six months. That should be time to better understand the strength and effectiveness of the wood before it burns up in the Earth’s atmosphere.

It reminds me of the old joke about the Americans inventing a billion-dollar pen to write upside down in space while the Russians simply used a pencil. Maybe the Japanese also have some to teach us.

Japanese Moon Mission: It’s Not Pretty, But it’s There

If you were wondering about the status of the latest Japanese Moon mission, you can rest assured that the Smart Lander for Investigation Moon (SLIM) lander is now safe on the surface of the moon. It also had time to release two small Lunar Excursion Vehicle (LEV) rovers on the lunar surface.

Above is an image from one of those LEV rover’s showing a precariously placed lander. It appears to be standing on its head. Unfortunately, the solar panels are facing west rather than east, as planned.

As noted earlier, it is possible that the SLIM lander could get enough sunlight in the next few days to reactivate for a short period, but after that the lunar evening will drop to -200°F. The lander and rovers are not built for such temperatures.

Update: Good news! As of earlier today (January 29), SLIM has power again and it is back online.

The ISS is Getting Pretty Crowded

The seven real astronauts on the International Space Station (ISS) are now playing host to four visitors for the next two weeks after the Axiom Mission 3 crew came aboard the station earlier today.

Unlike the last two Axiom missions, all three paying members of the Axiom Mission crew are being supported by various European governments:

  • Marcus Wandt, member of the European Space Agency’s (ESA) astronaut reserve (ticket paid by ESA and the Swedish National Space Agency);
  • Walter Villadei, a member of the Italian air force (ticket paid by the Italian air force); and
  • Alper Gezeravcı, a fighter pilot with the Turkish air force (ticket paid by the Turkish government).

At the price of $55 million per seat, I am hoping the governments and space agencies feel they are getting their money’s worth versus being part of the normal 6-month astronaut rotation.

Supposedly, the extra hands will be working on 30 experiments that the normal crew did not have time for, though I would imagine they would be the less important experiments if they would otherwise not be performed at all.

If all of this is truly important work, then I expect such demand will justify the need for commercial space stations down the line to continue the work of the ISS. However, I expect a good chuck of future space interest will come from the tourist side.

In the meantime, I just hope the toilets on board the ISS can deal with the extra passengers.

Note: So as not to give all the attention to the visitors, the current Expedition 70 crew members aboard station are:

  • NASA astronauts Jasmin Moghbeli and Loral O’Hara;
  • ESA astronaut Andreas Mogensen;
  • JAXA (Japan Aerospace Exploration Agency) astronaut Furukawa Satoshi; and
  • Roscosmos cosmonauts Konstantin Borisov, Oleg Kononenko, and Nikolai Chub.
