Space Quote: Getting Ready for Mars

“The space domain is critical to modern commerce, scientific discovery, and national security. The ability to accomplish leap-ahead advances in space technology through the DRACO nuclear thermal rocket program will be essential for more efficiently and quickly transporting material to the Moon and eventually, people to Mars.”

–Statement by Dr. Stefanie Tompkins, director of the Defense Advanced Research Projects Agency (DARPA), regarding its partnership with NASA on the Demonstration Rocket for Agile Cislunar Operations (DRACO) program to design and develop a nuclear thermal rocket engine that can bring a crewed mission to the Red Planet. It’s another encouraging step as we eventually move from the Moon to Mars.

Pic of the Week: Yogi Bear Spotted on Mars

This week’s image comes from the High Resolution Imaging Science Experiment (HiRISE) onboard the Mars Reconnaissance Orbiter. You don’t need to look too hard to see a bear in this photo.

Here is a summary of what you are seeing from the Lunar and Planetary Laboratory at the University of Arizona, which operates HiRISE:

There’s a hill with a V-shaped collapse structure (the nose), two craters (the eyes), and a circular fracture pattern (the head). The circular fracture pattern might be due to the settling of a deposit over a buried impact crater. Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?

Space Stories: Europeans Not Joining Chinese Space Station, the Milky Way is Odd, and Lucy has a New Target

Here are some recent stories of interest.

—Royal Astronomical Society: “European Space Agency Says it has No Plans to Send Astronauts to China’s Tiangong Space Station“

A top official with the European Space Agency said it had no plans to send European astronauts to the newly completed Chinese space station, making it clear for the first time that the agency is no longer committed to working with China in human space flight in the near future. “We are very busy supporting and ensuring our commitments and activities on the International Space Station,” ESA director general Josef Aschbacher told a press conference in Paris on Monday.

—Royal Astronomical Society: “Milky Way Found to be More Unique than Previously Thought“

Is the Milky Way special, or, at least, is it in a special place in the Universe? An international team of astronomers has found that the answer to that question is yes, in a way not previously appreciated. A new study shows that the Milky Way is too big for its “cosmological wall”, something yet to be seen in other galaxies. The new research is published in Monthly Notices of the Royal Astronomical Society.

—Southwest Research Institute: “SwRI-Led Lucy Team Announces New Asteroid Target“

NASA’s Lucy spacecraft will add another asteroid encounter to its 4-billion-mile journey. On Nov. 1, 2023, the Southwest Research Institute-led Lucy mission will get a close-up view of a small main belt asteroid to conduct an engineering test of the spacecraft’s innovative asteroid-tracking navigation system. The Lucy mission was already on course to break records by its planned visit of nine asteroids during its 12-year mission to tour the Jupiter Trojan asteroids, which orbit the Sun at the same distance as Jupiter. Originally, Lucy was not expected to get a close-up view of any asteroids until 2025, when it will fly by the main belt asteroid (52246) Donaldjohanson. However, the SwRI-led Lucy team identified a small, as-yet unnamed asteroid in the inner main belt as a potential new and useful target for the Lucy spacecraft.

Fortified Rockets? Ask the Pentagon

Earlier this month, The Wall Street Journal published an article, “Space Launches Should Withstand Chinese Challenge, Pentagon Mandate Says,” regarding new rocket requirements being developed by the US Department of Defense (DOD). It appears the Pentagon is worried about both the Russians and Chinese interfering with the launches of spy satellites. It doesn’t help to have an ongoing war in Ukraine where the Russians have already threatened US satellites. As a result, commercial rocket companies will need to meet some new specs on future missions.

DOD has already started the move to smaller satellites with dispersed missions to eliminate big space targets, which also allows for smaller companies to get into the game. More satellites launched from more locations (if not mobile locations) can assist the military with its missions whether it is facing errors or attacks. Even with some recent rocket mishaps, the story on the ground is positive as more companies join the industry while satellites get smaller and smaller.

This is not the space race the astronomy community wants to have, but the militarization of space is nothing new and is the primary reason we even started the space program. If the Blue Marble is not enough for us to understand the cost of war on the ground and in space, I am not sure what will work.

Video: More on ChatGPT and Astronomy

If you have questions about the future of AI and astronomy, I recommend you visit Cool World Lab’s latest video titled “ChatGPT Takes A College Level Astrophysics Exam.” The video addresses concerns that ChatGPT can be used by students to cheat on tests and homework, and highlights how the program is far from perfect (as shown below in a clip from the video).

To test the abilities of ChatGPT, the host submitted questions from an astronomy final exam to see what would happen. The results were interesting, particularly when math was involved. I do not want to give away the final score (you should watch the video for yourself), but let’s just say a good student can do better than ChatGPT at the moment.

What happens in the future with this new technology is anyone’s guess, though in-class tests may be the best approach if a teacher truly want to know the capabilities of a student. Cheating happens all the time, and it will probably happen on the homework. We just need to ensure the final test is a real test of the student alone
