A Day in Astronomy: Death of Hermann Oberth

On this day in 1989, rocket pioneer Hermann Julius Oberth died. He was born in Austria-Hungary in 1894 and at a young age was inspired by the rockets in the fictional stories by Jules Verne, such as From the Earth to the Moon.

Oberth’s interest in the stories of Verne led him to build his first rocket at the age of 14. His doctoral dissertation was on rocketry, he wrote books on rocketry, and he later joined an amateur rocketry group called the “Spaceflight Society” where he mentored other rocket enthusiasts, including Wernher von Braun.

Oberth was unable to get a security clearance to work on the Nazis V-2 rocket, thereby limiting his value to Americans following World War II, unlike Wernher von Braun and others who came to the United States under Project Paperclip and later assisted with NASA’s Apollo program.

Wernher von Braun was still able to get Oberth a position with the U.S. Army after the war and paid tribute to his mentor by stating:

I have a boundless admiration for the solitary genius which enabled him to bring into focus all of the essential elements of a gigantic concept, together with the human greatness which allowed him, in shy reserve, to bear with equanimity the “crucify him” as well as the “hosannas” of public opinion. I myself owe him a debt of gratitude not only for being the guiding light of my life but also for my first contact with the theoretical and practical aspects of rocket technology and space travel.

Oberth continues to be known today as the “Father of Space Travel.”

Holiday Message from the ISS

Santa’s gift-giving territory is pretty wide, but it is not clear whether he will make it to the International Space Station (ISS). However, the astronauts are ready if he does show up. They have hung their space boots by the airlock with cheer.

For the complete ISS holiday message, play this video from NASA astronauts Mike Fincke, Zena Cardman, and Chris Williams, along with Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui. The message was recorded on December 17, 2025.

Merry Christmas to all!

Space Stories: Russia to Re-purpose ISS Section, Second Mars Probe Approaching Lifespan, and Titan’s “Oceans” More Likely Ice

Here are some recent space-related stories of interest.

—ARSTecnica: “Russia is About to do the Most Russia Thing Ever with its Next Space Station“

For several years now, in discussing plans for its human spaceflight program beyond the International Space Station, Russian officials would proudly bring up the Russian Orbital Station, or ROS…Oleg Orlov, director of the Institute of Biomedical Problems of the Russian Academy of Sciences, said ROS will no longer be composed of entirely new modules. Rather, its core will be the Russian segment of the International Space Station. “The Scientific and Technical Council of Roscosmos supported this proposal and approved the deployment of a Russian orbital station as part of the Russian segment of the ISS,” Orlov reportedly said.

—Daily Galaxy: “NASA Faces Major Setback: One Mars Orbiter Lost and Another Is Expected to Shut Down Soon!“

NASA is losing critical communication links with its Mars missions. After recently losing contact with the MAVEN spacecraft, the agency faces the impending loss of the Mars Odyssey orbiter, which has been circling the Red Planet for over two decades. As both orbiters approach the end of their operational lifespans, NASA will soon have to find ways to maintain data relay capabilities for its rovers and other missions on the fourth planet.

—NASA/JPL: “NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean“

A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data suggests a more complicated picture: Titan’s interior is more likely composed of ice, with layers of slush and small pockets of warm water that form near its rocky core. Led by researchers at NASA’s Jet Propulsion Laboratory in Southern California and published in the journal Nature on Wednesday, the new study could have implications for scientists’ understanding of Titan and other icy moons throughout our solar system.

Executive Order to Ensure American Space Superiority

Just as Jared Isaacman, NASA’s new Administrator, started to settle into his new post, the White House updated the nation’s space priorities.

A new executive order on Thursday, titled “Ensuring American Space Superiority,” provides clear goals for NASA, which includes:

  • Returning to the Moon by 2028, and the establishment of initial elements of a permanent lunar outpost by 2030;
  • Deploying of nuclear reactors on the Moon and in orbit, including a lunar surface reactor ready for launch by 2030; and
  • Spurring private sector innovation and investment by upgrading launch infrastructure and developing a commercial pathway to replace the International Space Station by 2030.

Adding nuclear reactors as its own goal seems a little odd since it could simply be wrapped into the first goal related to a permanent lunar outpost, but maybe this is just to kick regolith into the eyes of the Chinese who announced a similar intention.

Returning to the Moon by 2028 will certainly be a challenge, but luckily Administrator Isaacman is showing no favorites when it comes to meeting this goal. This week he made this statement about plans to return to the Moon:

I don’t think it was lost on either vendor that whichever lander was available first to ensure that America achieves its strategic objectives on the moon is the one we were going to go with.

His friend Elon Musk was certainly listening, but so far we have not heard him say that the new NASA Administrator has a 2 digit IQ. Of course, it has only been a few days, though the honeymoon is likely to be very short.
