This week’s image shows the four US astronauts aboard the International Space Station (ISS) showing their Thanksgiving meal to all of us (contained in the white plastic bags). The astronauts pictured (clockwise from bottom left) are Nick Hague, Suni Williams, Butch Wilmore, and Don Pettit. You also watch a video where they share their holiday messages.
Last week’s Real Time with Bill Maher included an interview with astrophysicist Neil deGrasse Tyson, which did not go very well given the line of questioning. Mr. Maher was trying to entrap Dr. Tyson into some anti-woke politics, but he did not play along.
With all the topics Dr. Tyson could address on the show, it was a waste of time for viewers to witness this ambush. Mr. Maher continues to forget that he is a comedian and his guests come onto the show to have some fun. You can listen to the mess here.
Fortunately, the Overtime show after the main show, which focuses on questions from the audience, finally addressed some space-related questions, including one about Mr. Musk’s plans to go to Mars. Dr. Tyson said the costs, risks, and return on investment do not currently justify such a mission. However, he pointed out that once it becomes a space race with China then it may be something worth pursuing.
It was an interesting answer, and yet it seemed to ignore that we already have decided as a nation to go to Mars under the Artemis program even with the cost, risks, and lack of return on investment. It has a different time-table than Mr. Musk’s vision, but it is a plan that seems to be in place at the moment.
Maybe Dr. Tyson believes that too will be a space race similar to what it going on now with China regarding a Moon landing. It seems more likely than not at the moment.
Anyway, ignore the main show and tap into the Overtime show for some fun space-related discussions.
“We believe once governments and the Artemis missions have re-established human presence on the moon, commercial services will follow that…every operation on the moon will require power”.

Here are some recent stories on Mars.
—Earth.com: “China’s Mars Zhurong Rover Finds an Ocean Shoreline on the Red Planet“
The Chinese Mars rover Zhurong is adding an exciting twist to the story and history of water on Mars. After landing in southern Utopia Planitia on Mars in May 2021, the now-defunct Zhurong rover went to work exploring the Martian surface, and its latest findings might just change the way we think about the Red Planet. Bo Wu and a team of researchers from Hong Kong Polytechnic University believe they’ve found compelling evidence of an ocean shoreline for a massive body of water that once covered Mars’ northern lowlands.
—New York Times: “An Asteroid’s Destruction May Have Given Mars Rings, Then Moons“
Something’s not quite right about the moons of Mars. They are too small — Phobos is 17 miles across, and Deimos is a mere nine miles in length. And they aren’t round, but lumpy, misshaped objects. Frankly, they don’t resemble moons at all…A study published Wednesday in the journal Icarus makes a case that the moons did indeed start out in asteroid form. But it’s not the genesis everyone was expecting. Using supercomputer-powered simulations, scientists describe a situation in which a large-enough asteroid was captured by Mars long ago and torn to shreds by the planet’s gravity, briefly forming a debris cloud — and possibly a ring system — around Mars that ultimately clumped together to form two moons.
—Astrobiology News: “Meteorite Contains Evidence Of Liquid Water On Mars 742 Million Years Ago“
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth somewhere near Purdue and is one of the few meteorites that can be traced directly to Mars. This meteorite was rediscovered in a drawer at Purdue University in 1931 and therefore named the Lafayette Meteorite. During early investigations of the Lafayette Meteorite, scientists discovered that it had interacted with liquid water while on Mars. Scientists have long wondered when that interaction with liquid water took place. An international collaboration of scientists including two from Purdue University’s College of Science have recently determined the age of the minerals in the Lafayette Meteorite that formed when there was liquid water. The team has published its findings in Geochemical Perspective Letters.
The International Space Station (ISS) had another visitor on Saturday morning – this time a Russian Soyuz capsule bringing about three tons of food, fuel, and supplies to the station as part of its Progress MS-29 mission (Progress 90 mission to NASA).
The Russian News Agency provided a list of items delivered to the ISS and also noted that the resupply mission also included Christmas gifts for the crew.
Here are the items delivered:
…869 kg of refueling propellant, 420 liters of potable water and 43 kg of pressurized nitrogen, and also 1,155 kg of material and equipment in the dry cargo hold, in particular, for experiments dubbed Vampire (growing crystals in an electric vacuum furnace), BTN-Neutron-2 (studying the neutron spectrum) and 3D Print (3D printing of polymer materials).
It nice that the Russians took the time to assist Santa with his gift giving.
Of course, the U.S. Department of Defense’s North American Aerospace Defense Command (NORAD) will be tracking the actions of Santa here on Earth this year, so be sure to visit the site closer to Christmas next month.
