Here are some recent stories of interest.

—NDTV: “NASA Announces Plans To Build First Railway System On Moon“

As the National Aeronautics and Space Administration (NASA) readies to return astronauts to the moon, it has announced its plans to build a levitating robot train on the lunar surface. In a blog post, the American space agency provided details about the project called “Flexible Levitation on a Track (FLOAT)”, which aims to provide a “robotic transport system” to support future lunar activities of astronauts visiting the moon. The transport system will be critical to the daily operation of a sustainable lunar base in the 2030s, NASA said in a statement. 

—IEEE Spectrum: “Commercial Space Stations Approach Launch Phase“

A changing of the guard in space stations is on the horizon as private companies work toward providing new opportunities for science, commerce, and tourism in outer space. Blue Origin is one of a number of private-sector actors aiming to harbor commercial activities in low Earth orbit (LEO) as the creaking and leaking International Space Station (ISS) approaches its drawdown. Partners in Blue Origin’s Orbital Reef program, including firms Redwire, Sierra Space, and Boeing, are each reporting progress in their respective components of the program. The collaboration itself may not be on such strong ground. Such endeavors may also end up slowed and controlled by regulation so far absent from many new, commercial areas of space.

—Newsweek: “Russia Reveals New China Nuclear Moon Base Details“

Details about joint plans between Moscow and Beijing to put a lunar nuclear reactor within the next decade have been revealed by the head of Russia’s space agency. In March, Roscosmos announced plans to work with China to build an automated nuclear reactor to power a proposed lunar base that the two countries would operate together within the next decade. To construct the site, Roscosmos director general Yury Borisov said two months ago it was looking at using nuclear-powered rockets to transfer cargo to the moon, but had not yet figured out how to build these spacecraft safely. In an article published Wednesday by state news outlet RIA Novosti, Borisov said that development of the plant was underway and the countries were working on creating experimental and research facilities as part of the project.

Video: Check Out Aeon Astronomy & Space Travel Videos

Posted on by onespaceman2000

Aeon is a website of ideas run by Aeon Media. It’s mission is to explore and communicate knowledge that addresses our shared need to make sense of the world.

While it covers quite a few topics, I wanted to highlight some of its videos on astronomy and space travel. Below are just a few I recommend. You should explore the site on your own to learn more.

Check them out and many more. It is a well organized site that operates on donations, so don’t be afraid to contribute if you really enjoy the pieces.

Don’t Miss the Northern Lights

Tonight you can still capture the Northern Lights here in the U.S. After an 11-year absence. The solar event will have the greatest show in the Ohio River Valley through the Midwest and into the Pacific Northwest (see CNN map below). Amazingly, the show was seen as far south as Florida yesterday evening.

The good news is that the solar burst has not been causing damage to the power grid and satellites. Sweden and South Africa were not so lucky in 2003.

Space Quote: Congressional Appeal for More NASA Funding

Posted on by onespaceman2000

“An improved appropriation for FY 2025 of $9 billion for SMD will give the agency the necessary resources to pursue Decadal priorities such as the Earth System Observatory, Geophysical Dynamics Constellation, Habitable Worlds Observatory, and Mars Sample Return, while maintaining our nation’s highly-skilled workforce and fleet of operating and developing spacecraft including the Chandra X-Ray Observatory, Hubble Space Telescope, Perseverance and Curiosity rovers, among others. These investments in our high-tech STEM workforce and university systems will provide positive value to every congressional district.”

-Statement in a May 1, 2024 letter to the House Appropriations Subcommittee on Commerce, Justice, Science, and Related Agencies from 44 Members of Congress regarding increased funding to NASA related to its Science Mission Directorate (SMD). The letter notes that “…the FY 2025 President’s Budget Request of $7.6 billion for NASA Science represents a $1.1 billion decrease in purchasing power from its peak in FY 2020 and would be the smallest budget in eight years when adjusted for inflation.”

Pic of the Week: Little Dumbbell Nebula

This week’s image comes from the NASA/European Space Agency’s Hubble Space Telescope. It shows what is called the Little Dumbbell Nebula, more formally called  Messier 76, M76, or NGC 650/651, which is about 3,400 light-years away. The image is being shared as part of the celebration of Hubble’s 34th anniversary, which is discussed in this video.

Here is more on the nebula from NASA:

M76 is classified as a planetary nebula, an expanding shell of glowing gases that were ejected from a dying red giant star. The star eventually collapses to an ultra-dense and hot white dwarf. A planetary nebula is unrelated to planets, but have that name because astronomers in the 1700s using low-power telescopes thought this type of object resembled a planet.

M76 is composed of a ring, seen edge-on as the central bar structure, and two lobes on either opening of the ring. Before the star burned out, it ejected the ring of gas and dust. The ring was probably sculpted by the effects of the star that once had a binary companion star. This sloughed off material created a thick disk of dust and gas along the plane of the companion’s orbit. The hypothetical companion star isn’t seen in the Hubble image, and so it could have been later swallowed by the central star. The disk would be forensic evidence for that stellar cannibalism.

The primary star is collapsing to form a white dwarf. It is one of the hottest stellar remnants known at a scorching 250,000 degrees Fahrenheit, 24 times our Sun’s surface temperature. 
The sizzling white dwarf can be seen as a pinpoint in the center of the nebula. A star visible in projection beneath it is not part of the nebula.



Pinched off by the disk, two lobes of hot gas are escaping from the top and bottom of the “belt,” along the star’s rotation axis that is perpendicular to the disk. They are being propelled by the hurricane-like outflow of material from the dying star, tearing across space at two million miles per hour. That’s fast enough to travel from Earth to the Moon in a little over seven minutes! This torrential “stellar wind” is plowing into cooler, slower-moving gas that was ejected at an earlier stage in the star’s life, when it was a red giant. Ferocious ultraviolet radiation from the super-hot star is causing the gases to glow. The red color is from nitrogen, and blue is from oxygen.


Given our solar system is 4.6 billion years old, the entire nebula is a flash in the pan by cosmological timekeeping. It will vanish in about 15,000 years.
