Podcast: The Future of Human Mars Exploration

Posted on by onespaceman2000

The Mars Society’s Red Planet Live Podcast will be joined by Dr. Robert Zubrin on March 4th for a discussion about the future of human Mars exploration, what it will take to get boots on the Red Planet, and how we can build our first off-world settlement.

Dr. Zubrin is the Founder and President of The Mars Society, as well as the author of numerous books on Mars and other space-related topics. One of his latest books is The New World on Mars: What We Can Create on the Red Planet, which was issued in February 2024. As short summary of the book from the publisher’s site is provided below. It should be a useful primer for the upcoming discussion.

SpaceX, Blue Origin, and Virgin Galactic are building fleets of space vehicles to make interplanetary travel as affordable as Old-World passage to America. We will settle on Mars, and with our knowledge of the planet, analyzed in depth by Dr. Zubrin, we will utilize the resources and tackle the challenges that await us. What we will we build? Populous Martian city-states producing air, water, food, power, and more. Zubrin’s Martian economy will pay for necessary imports and generate income from varied enterprises, such as real estate sales—homes that are airtight and protect against cosmic space radiation, with fish-farm aquariums positioned overhead, letting in sunlight and blocking cosmic rays while providing fascinating views. Zubrin even predicts the Red Planet customs, social relations, and government—of the people, by the people, for the people, with inalienable individual rights—that will overcome traditional forms of oppression to draw Earth immigrants. After all, Mars needs talent.

Boeing Layoffs are Bad News for NASA’s Artemis Program

As if things could not get worse over at NASA, it now has to contend with Boeing’s financial problems. Boeing is considering laying off about 400 employees working on the Space Launch System (SLS), or about one third of the employees working on the system. The SLS is the backbone of the Artemis program returning the U.S. to the Moon and eventually Mars.

This follows problems last year with Boeing’s Starliner mission to the International Space Station. The two astronauts on the first manned Starliner mission are still on the station due to safety concerns about their return to Earth on the same spacecraft that brought them to the station.

None of this portends well for Boeing, NASA, or the space industry in general. This may simply throw more work towards SpaceX, making NASA more reliant on a company whose head seems more interesting in tearing down the U.S. government than focusing on the U.S. space mission. Besides, after the loss of the latest Starship, SpaceX is not in any position to replace what would be lost with the SLS. The end of the SLS may simply mean the end of any chance for the U.S. to beat China to the Moon.

This may serve the interests of Elon Musk, who always preferred going Mars, but given the lack of preparation for such a mission beyond a rocket (including lessons learned from the Artemis program), it seems even the Mars mission may be drifting into the sunset.

We need a strong NASA and clear mission priorities that are achievable in the short term. With a billionaire tourist taking over as NASA’s new leader, we need to be very careful NASA does not simply become another Dancing with the Stars for C-list celebrity wannabes.

Moon Rock Moves from White House

As the new administration decorates the White House’s Oval Office, it was determined that a lunar rock no longer needs to be present. The rock from the last Apollo mission, labeled “Lunar Sample 76015,143.” was provided to the Biden administration back in 2021 to remind him of U.S. efforts to return to the Moon.

The inscription on the Moon rock reads:

Apollo 17 astronaut Ronald Evans and moonwalkers Harrison Schmitt and Eugene Cernan, the last humans to set foot on the Moon, chipped this sample from a large boulder at the base of the North Massif in the Taurus-Littrow Valley, 3 km (almost 2 miles) from the Lunar Module. This 332 gram piece of the Moon (less than a pound), which was collected in 1972, is a 3.9-billion-year-old sample formed during the last large impact event on the nearside of the Moon, the Imbrium Impact Basin, which is 1,145 km or 711.5 miles in diameter.

The irregular sample surfaces contain tiny craters created as micrometeorite impacts have sand-blasted the rock over millions of years. The flat, sawn sides were created in NASA’s Lunar Curation Laboratory when slices were cut for scientific research. This ongoing research is imperative as we continue to learn about our planet and the Moon, and prepare for future missions to the cislunar orbit and beyond.

So does this mean the Moon is out, or did it not match the new drapes? Or is President Trump hoping to add his own Moon rock to his office after a successful Artemis mission?

It is not clear where the Moon stands in the current priorities of this White House given its ongoing efforts to push NASA employees into retirement or resignation, end scientific meetings, and eliminate all efforts at diversity at the agency.

Maybe Mars is the new target, but even that seems further off as Elon Musk burrows into government programs he know nothing about while the latest Starship disintegrated over the Caribbean.

Space missions take focus, which seems to be elsewhere at the moment.

Maybe the rock should stay in the Oval Office for the time being to remind the current administration what our country can do when it has a president with a vision that brings everyone together to accomplish an amazing task.

Space Stories: Farewell to Bill Nelson, an Unpredictable Universe, and Ponds and Lakes on Mars

Here are some recent stories of interest.

—WESH.com: “NASA Administrator Bill Nelson Writes Letter to Next Leader, Reflects on Legacy and Future of Space Exploration“

In a heartfelt letter addressed to the 15th Administrator of NASA, Bill Nelson expressed his admiration for the agency’s workforce and the immense honor of leading the organization dedicated to space exploration. Nelson, who has a rich history with NASA, having flown on the Space Shuttle Columbia and served as a U.S. Senator from Florida, emphasized the exceptional nature of the NASA team. He noted that the agency embodies a “can-do spirit” that exemplifies American ingenuity and leadership in space.

—Duke University: “Dan Scolnic Shows that the Universe Is Still Full of Surprises“

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous — and highly debated — results had shown: The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics. This discrepancy between model and data became known as the Hubble tension. Now, results published in the Astrophysical Journal Letters provide even stronger support to the faster rate of expansion. “The tension now turns into a crisis,” said Dan Scolnic, who led the research team.

—Caltech: “Signatures of Ice-Free Ancient Ponds and Lakes Found on Mars“

Researchers have discovered two sets of ancient wave ripples on Mars, signatures of long-dried bodies of water preserved in the rock record. Wave ripples are small undulations in the sandy shores of lakebeds, created as wind-driven water laps back and forth. The two sets of ripples indicate the former presence of shallow water that was open to the Martian air, not covered by ice as some climate models would require.

Space Quote: Next Step Mars?

“We will pursue our manifest destiny into the stars, launching American astronauts to plant the Stars and Stripes on the planet Mars.”

-Inaugural statement by President Trump on January 20, 2024. He may want to check with NASA on the Artemis program given that the planned trip to the Moon has already cost taxpayers billions of dollars. He might also want to read a recent Politico story that discusses congressional preference for a Moon first program. The story quotes Texas Republican Brian Babin, who stated, “To bypass the moon would be a mistake.” It might also look bad to give the Moon to the Chinese long before we figure out a way to safely get to Mars. For all of Musk’s talk on this matter, the loss of a Starship rocket last week was not encouraging. We are having trouble enough getting ready to return to the Moon.
