Here are some recent space-related stories of interest.

—Time: “China’s Imperiled Astronauts Illustrate the Dangers of Space Debris“

No trip to space can be counted a success unless you make it safely back to Earth…And it’s a lesson that was learned anew this week by the taikonauts—Chinese astronauts—Chen Dong, Chen Zhongrui, and Wang Jie. The trio arrived at China’s Tiangong Space Station aboard their Shenzhou-20 spacecraft on April 24, and were set to come home on Nov. 5, handing the keys to the station over to the three-person crew of Shenzhou-21, who arrived on Oct. 31. But that was not to be. Not long before Shenzhou-20 was set to carry the three home it was struck by a piece of space debris, leaving cracks in one of its windows. That can be deadly in a spacecraft that is supposed to remain airtight both in the vacuum of space and in the steadily thickening atmosphere as it returns to Earth.

A powerful geomagnetic storm that dazzled skywatchers across the Northern Hemisphere earlier this month also affected life aboard the International Space Station (ISS). During the Nov. 11-12 solar storm, Russian cosmonauts temporarily relocated their sleeping quarters as a precaution against increased radiation exposure, NASA confirmed.

—Space News: “Dream Chaser Completes Key Tests Ahead of First Flight“

Sierra Space has completed key testing milestones for its Dream Chaser vehicle as the company explores both civil and national security missions for the spaceplane. The company announced Nov. 13 that the first Dream Chaser vehicle, Tenacity, completed electromagnetic interference and compatibility testing at NASA’s Kennedy Space Center...While Sierra Space is emphasizing national security uses, the company is keeping open the option of using Dream Chaser to support the ISS or future commercial space stations, known as commercial low Earth orbit destinations, or CLDs.

Pic of the Week: The New Glenn Rocket Booster Returns

Today’s image comes from Blue Origin, which successfully completed it second launch of it New Glenn rockets, sending two NASA Martian probes into orbit. The image shows the reusable rocket booster right after it landed on a platform in the Atlantic Ocean.

Acting NASA Administrator Sean Duffy stated:

Congratulations to Blue Origin, Rocket Lab, UC Berkeley, and all of our partners on the successful launch of ESCAPADE…This heliophysics mission will help reveal how Mars became a desert planet, and how solar eruptions affect the Martian surface. Every launch of New Glenn provides data that will be essential when we launch MK-1 through Artemis. All of this information will be critical to protect future NASA explorers and invaluable as we evaluate how to deliver on President Trump’s vision of planting the Stars and Stripes on Mars.

SpaceX now has another competitor for military and space missions, which is good for everyone (including SpaceX since it will keep them focused).

The New Glenn Launch to Mars Scheduled for Tomorrow

Blue Origin’s New Glenn rocket is scheduled to be launched tomorrow afternoon with two Martian probes on board. A lot is riding on tomorrow’s launch. The mission is important for Blue Origin, as it tests its new rocket with its first real mission. It is also important to NASA, which is using the probes to better understand the Martian atmosphere.

Blue Origin’s reusable New Glenn rocket will put it in direct competition with SpaceX for future NASA missions. This redundancy is needed, particularly with SpaceX seeming to struggle with its projects related to the Atemis lunar mission.

The $100 million Martian mission, called Escape and Plasma Acceleration and Dynamics Explorers (EscaPADE), involves a pair of identical spacecraft with a the goal of analyzing:

  1. how Mars’ magnetic field guides particle flows around the planet,
  2. how energy and momentum are transported from the solar wind through the magnetosphere, and
  3. what processes control the flow of energy and matter into and out of the Martian atmosphere.

The two probes will be launched towards Lagrange Point 2, where they will sit for more than a year before making an approach towards Mars. The probes are expected to go into orbit around Mars in September 2027.

Godspeed to Blue Origin and NASA.

Update: The launch has been delayed due to bad weather. The next attempt will be on November 12th.

If at First You Don’t Succeed: Jared Isaacman is Really Back

President Trump has had a change of heart on Jared Isaacman, his initial nominee for NASA administrator until he withdrew that nomination earlier this year.

Earlier today, the President posted the following:

Jared’s passion for Space, astronaut experience, and dedication to pushing the boundaries of exploration, unlocking the mysteries of the universe, and advancing the new space economy, make him ideally suited to lead NASA into a bold new era.

So what has changed in the last few months to make Mr. Isaacman “ideally suited” to lead NASA as compared to when he was determine unsuitable? I cannot think of anything other than the end of the President’s feud with Elon Musk. Of course, that was recently replaced with Elon Musk’s feud with acting NASA Administrator Sean Duffy, who proposed reopening competition for the first manned Moon landing this century due to delays with SpaceX’s Starship.

Will Mr. Isaacman save Musk’s Moon mission? He may calm some of the acrimony for the time being, but any new NASA administrator had better have a solid plan to get Americans back on the Moon before China does. Mr. Isaacman may be friends with Mr. Musk, but should he be confirmed he will head a weakened space agency that is struggling with a complex Moon mission that may be much less complex without the Starship refueling plans. In fact, Blue Origin just submitted a new Moon mission plan that drops this refueling altogether.

It is not impossible the winds will shift again, leaving Mr. Isaacman adrift once more. That is how it is in Washington these days. Fickle leadership leads to fickle decision-making and fickle planning.

The Chinese are not having these issues at the moment as they aim to be on the Moon by 2030.

Starship Has Successful 11th Launch

The Starship launches have been going a little better, with yesterday’s 11th launch meeting its goals, including the release of a practice satellite.

Following the launch, SpaceX stated:

Every major objective of the flight test was achieved, providing valuable data as we prepare the next generation of Starship and Super Heavy...Focus now turns to the next generation of Starship and Super Heavy, with multiple vehicles currently in active build and preparing for tests. This next iteration will be used for the first Starship orbital flights, operational payload missions, propellant transfer, and more as we iterate to a fully and rapidly reusable vehicle with service to Earth orbit, the Moon, Mars, and beyond.

I like that ending, which sounds like something you would hear on the airport bus as you approach the rental lot, “…with service to Earth orbit, the Moon, Mars, and beyond.”

Let’s just hope this bus can get NASA to its next destination on time.
