The House Committee Dodged a Killer Asteroid

The House Committee on Science, Space, and Technology, which oversees NASA’s programs, may have a chance to get some things done this year. Earlier in the week, New York Congressman George Santos stepped down from the Committee on Science, Space, and Technology as well as the House Committee on Small Business. With all of the problems following this man, his presence on either committee would have been a pure distraction.

The House Committee on Science, Space, and Technology has a broad jurisdiction beyond just NASA:

The Committee on Science, Space, and Technology has jurisdiction over all energy research, development, and demonstration, and projects thereof and all federally owned or operated non-military energy laboratories; astronautical research and development, including resources, personnel, equipment, and facilities; civil aviation research and development; environmental research and development; marine research; commercial application of energy technology; National Institute of Standards and Technology, standardization of weights and measures and the metric system; National Aeronautics and Space Administration; National Science Foundation; National Weather Service; outer space, including exploration and control thereof; science scholarships; scientific research, development, and demonstration, and projects therefor. The Committee on Science, Space, and Technology shall review and study, on a continuing basis, laws, programs, and Government activities relating to non-military research and development.

Given the Artemis program as well as the other NASA endeavors currently underway, the Committee should be focusing as much time as possible on space missions rather than bogus resumes and lies to the public.

NASA-related hearings from last year include:

We need a serious Congress if we are going to conduct serious science and space exploration. Let’s hope Washington DC can keep its focus on the real stars (rather than the political black holes that can suck in all light and common sense).

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?

In Case You Missed It: More Trash, This Time on Mars

In an earlier post, I noted the amount of poop as well as other trash left behind on the Moon from prior lunar missions. Well, Cagri Kilic, a Postdoctoral Research Fellow at West Virginia University, also ventured a guess at the amount of human trash that has already accummulated on the surface of Mars.

In the article he authored for The Conversation back in September, “Mars is Littered with 15,694 Pounds of Human Trash from 50 Years of Robotic Exploration,” he provided a figure as well as his methodology:

When you add up the mass of all spacecraft that have ever been sent to Mars, you get about 22,000 pounds (9979 kilograms). Subtract the weight of the currently operational craft on the surface – 6,306 pounds (2,860 kilograms) – and you are left with 15,694 pounds (7,119 kilograms) of human debris on Mars.

That’s a fair amount of trash and defunct equipment. And we are still adding to this toll, with plans to eventually send humans and material for settlements to the Red Planet. The same goes for the Moon, with multiple bases planned by the US, China, and Russia.

I expect we will see some other estimates in the future on what has been left on other planets, moons, and asteroids. And let’s not forget the five spacecraft we have shot beyond Pluto.

We humans do tend to leave a mess where ever we go. We may be explorers, but Boy Scouts would take issue given their principle “Leave No Trace.”

Space Stories: Passing of Apollo Astronaut Walter Cunningham, Opal on Mars, and Juno Recovers

Here are some recent stories of interest.

—NASA: “Apollo Astronaut Walter Cunningham Dies at 90“

Former astronaut Walter Cunningham, who flew into space on Apollo 7, the first flight with crew in NASA’s Apollo Program, died early Tuesday morning in Houston. He was 90 years old. “Walt Cunningham was a fighter pilot, physicist, and an entrepreneur – but, above all, he was an explorer. On Apollo 7, the first launch of a crewed Apollo mission, Walt and his crewmates made history, paving the way for the Artemis Generation we see today,” said NASA Administrator Bill Nelson. “NASA will always remember his contributions to our nation’s space program and sends our condolences to the Cunningham family.”

—New Atlas: “Curiosity Finds Opal on Mars – a Possible Water Source for Astronauts“

NASA’s Curiosity rover has discovered opal on Mars. The deposits may prove to be valuable to future Martian explorers not as jewelry but as a potential source of water. Opal is formed when water weathers silica-rich rocks, forming a solution that settles into cracks and crevices in the rock. Over time, this solution hardens into a solid lump that can be cloudy and dull or a dazzling display of color. Most supplies come from either Australia or Ethiopia, but now a new source has been discovered – Mars.

—Space.com: “Juno Spacecraft Recovering its Memory After Mind-blowing Jupiter Flyby, NASA Says“

NASA’s Juno probe is continuing to recover its memory at Jupiter after a data disruption interrupted communications between the spacecraft and its operators on Earth following a flyby of the giant planet in December. The Juno spacecraft’s latest flyby of Jupiter, its 47th close pass of the planet, was completed on Dec. 14. But as its operators at NASA’s Jet Propulsion Laboratory were receiving science data from the flyby they found they could no longer directly access the spacecraft’s memory. The team successfully rebooted Juno’s computer and on Dec. 17 they placed the spacecraft into “safe mode” with only essential systems operating as a precaution.
