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.

A Day in Astronomy: Loss of the Apollo 1 Astronauts

On this day in 1967, the Apollo 1 capsule caught fire on the launchpad, killing the three astronauts in the capsule – Virgil “Gus” Grissom, Ed White, and Roger Chaffee.

A frustrated Gene Kranz, NASA flight director, had this to say shortly after the fire and tragic loss of three astronauts:

Spaceflight will never tolerate carelessness, incapacity, and neglect. Somewhere, somehow, we screwed up. It could have been in design, build or test. Whatever it was, we should have caught it. We were too gung-ho about the schedule, and we locked out all of the problems we saw each day in our work. Every element of the program was in trouble and so were we. The simulators were not working, Mission Control was behind in virtually every area, and the flight and test procedures changed daily. Nothing we did had any shelf life. Not one of us stood up and said, “Dammit, stop!” I don’t know what Thompson’s committee will find as the cause, but I know what I find. We are the cause! We were not ready! We did not do our job. We were rolling the dice, hoping that things would come together by launch day, when in our hearts we knew it would take a miracle. We were pushing the schedule and betting that the Cape would slip before we did.

Did the Apollo space program recover? Absolutely. Did NASA avoid deaths on future space missions. Not at all. Do we give up on human space missions or keep moving forward? I think you know the answer to that one.

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 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.
