Here are some recent stories of interest.

—Aviation Week Network: “Safety Panel Raises Commercial Space Station Transition Concerns“

Concerns over a “very tight” timeline for NASA to transition human low-Earth-orbit operations from the International Space Station (ISS) to commercial successors tops a list of seven concerns raised by an agency safety panel. The latest annual report by NASA’s Aerospace Safety Advisory Panel’s (ASAP) was released Jan. 25. The 56-page report expresses concerns over sufficient evidence of a viable business case to make NASA one of multiple tenants of at least one ISS successor. The effort is currently supported by NASA and the European, Japanese, Russian and Canadian space agencies.

—Astronomy.com: “Vertex Moon Mission Getting Closer to Launch“

 A new era in lunar research is coming, and Lunar Vertex is getting ready to lead the way. Lunar Vertex is NASA’s first so-called PRISM mission (Payloads and Research Investigations on the Surface of the Moon). PRISM taps into the Commercial Lunar Payload Services program that uses privately built landers to deliver NASA science and other payloads to the lunar surface. PRISM missions are meant to be lower-cost, faster-to-flight programs. There is a mass limit of just over 100 pounds (45 kilograms) — so the science instruments have to be small — and the budget for the first PRISM suite is just $30 million (excluding the lander and the launch vehicle). Lunar Vertex is first in line, and recently has hit a number of major milestones on its way to a June 2024 launch.

—NASA: “Shrinking Moon Causing Moonquakes and Faults Near Lunar South Pole“

As NASA continues to make progress toward sending astronauts to the lunar South Pole region with its Artemis campaign, data from a NASA-funded study is helping scientists better understand this strategic part of the Moon. The study presents evidence that moonquakes and faults generated as the Moon’s interior gradually cools and shrinks are also found near and within some of the areas the agency identified as candidate landing regions for Artemis III, the first Artemis mission planned to have a crewed lunar landing.

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.

The End of Two Moon Missions?

Within a two day period, we saw one Moon lander become a burning wreck plummeting towards Earth and another land on the Moon with an immediate problem that threatened its mission. The Moon may be closer, but it is becoming a hazardous place for space missions, similar to Mars.

First, the NASA-contracted Astrobotic Peregrine lander mission ended yesterday as the spacecraft entered the Earth’s atmosphere and burned up. The $108 Moon mission burned up with its cargo, including NASA’s scientific instruments, various rovers, and the DNA remains of humans whose families hoped would be at rest on the Moon’s surface. I expect a few Native Americans may be saying “I told you so” to themselves.

It was almost comical reading a Scientific American article trying to put a good spin on the lost cargo:

In addition, all nine of the payloads that were designed to communicate with Peregrine successfully returned data to Earth. Iris, a rover built by Carnegie Mellon University, sent back a “Hello Earth!” message. COLMENA, a set of five small rovers built by the Mexican Space Agency, also succeeded in sending data back—making it the first Mexican scientific instrument to operate in the moon’s vicinity.

I expect “Hello Earth!” fell far below the ground crew’s expectations, but I guess you take what you can get. And Mexico will probably hold off on any celebrations for the moment.

The second set of bad news related to the latest Japanese Moon mission. The good news is that the Smart Lander for Investigation Moon (SLIM) spacecraft was a success in terms of a soft landing on the Moon. The problem is that the solar array is not getting sufficient solar power for the lander to remain operational for more than a few hours. It is possible that the situation may correct itself as the sunshine shifts over time, but this is not a good start to the mission.

Whatever happens, Japan can still claim to be the fifth nation to successfully land on the Moon. It is not perfect, but the Japanese have more reason to celebrate than the Mexicans at this point.

Will China Beat Us to the Moon?

With the newly announced delays related to the Artemis lunar program, it is fair to ask whether the U.S. might fall behind the Chinese when it comes to a crewed lunar mission (of course, we won that battle 50 years ago, but you know that I mean).

All reports indicate that the Chinese wants to place humans on the Moon by 2030, but they are not expected to beat the Artemis timetable of a lunar landing in 2026. Of course, it is important that NASA stick to this timetable.

NASA Administrator Bill Nelson recently stated:

I do not have a concern that China is going to land before us…I think that China has a very aggressive plan. I think they would like to land before us, because that might give them some PR coup. But the fact is that I don’t think they will. I think it is true that their date that they announced keeps getting earlier. But specifically, with us landing in September of ’26, that will be the first landing.

Obstacles remain on what will prove to be a difficult mission even if it is a repeat. We already saw Russia’s failed attempt to simply land on the Moon last year, and the problems with last week’s NASA-funded commercial launch towards the Moon was worrying.

Nothing can be taken for granted in this new space race.

Sidebar: The Griffin Mission

I did not follow up on yesterday’s post when Astrobotic said it was moving onto its Griffin mission. What is that?

The Griffin mission involved a lunar lander as well, but this time the destination will be the Moon’s South Pole. The lander will deploy NASA’s Volatiles Investigating Polar Exploration Rover (VIPER), which will be searching for water.

The Griffin/VIPER duo was supposed to be on the Moon already, but we already know about delays. I expect the delays will only lengthen as NASA and Astrobotic try to better understand what happened earlier this week with the Peregine lunar lander. NASA does not want to lose a rover.

NASA’s launch website now still has the VIPER landing scheduled for late 2024.
