—Royal Astronomical Society: “European Space Agency Says it has No Plans to Send Astronauts to China’s Tiangong Space Station“

A top official with the European Space Agency said it had no plans to send European astronauts to the newly completed Chinese space station, making it clear for the first time that the agency is no longer committed to working with China in human space flight in the near future. “We are very busy supporting and ensuring our commitments and activities on the International Space Station,” ESA director general Josef Aschbacher told a press conference in Paris on Monday.

—Royal Astronomical Society: “Milky Way Found to be More Unique than Previously Thought“

Is the Milky Way special, or, at least, is it in a special place in the Universe? An international team of astronomers has found that the answer to that question is yes, in a way not previously appreciated. A new study shows that the Milky Way is too big for its “cosmological wall”, something yet to be seen in other galaxies. The new research is published in Monthly Notices of the Royal Astronomical Society.

—Southwest Research Institute: “SwRI-Led Lucy Team Announces New Asteroid Target“

NASA’s Lucy spacecraft will add another asteroid encounter to its 4-billion-mile journey. On Nov. 1, 2023, the Southwest Research Institute-led Lucy mission will get a close-up view of a small main belt asteroid to conduct an engineering test of the spacecraft’s innovative asteroid-tracking navigation system. The Lucy mission was already on course to break records by its planned visit of nine asteroids during its 12-year mission to tour the Jupiter Trojan asteroids, which orbit the Sun at the same distance as Jupiter. Originally, Lucy was not expected to get a close-up view of any asteroids until 2025, when it will fly by the main belt asteroid (52246) Donaldjohanson. However, the SwRI-led Lucy team identified a small, as-yet unnamed asteroid in the inner main belt as a potential new and useful target for the Lucy spacecraft.

Space Stories: JWST Confirms Earth-Size Exoplanet, Russia Sending Rescue Mission to ISS, and IO Erupts

—Webb Space Telescope: “NASA’s Webb Confirms Its First Exoplanet“

Researchers confirmed an exoplanet, a planet that orbits another star, using NASA’s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter. The research team is led by Kevin Stevenson and Jacob Lustig-Yaeger, both of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.

—ABC News: “Russia Will Launch New Capsule to Return Space Station Crew“

Russia will send up a new capsule next month to bring back three space station crew members whose original ride home was damaged, officials said Wednesday. The two Russians and one American will stay several extra months at the International Space Station as a result of the capsule switch, possibly pushing their mission to close to a year, NASA and Russian space officials told reporters.

—MSN Science Alert: “Massive Volcanic Outburst Detected on Jupiter’s Hellish Moon Io“

In the space around Jupiter, a torus of plasma created and fed by Io’s volcanic emissions grew significantly richer between July and September of last year and persisted until December, showing the moon underwent a spate of volcanic activity that released a huge amount of material. For something that’s just a little bit bigger than Earth’s Moon, Io is an absolute beast of volcanism. It’s bristling with volcanoes, with around 150 of the 400 known volcanoes erupting at any given time, creating vast lakes of molten lava.

Space Stories: Passing of Apollo Astronaut Walter Cunningham, Opal on Mars, and Juno Recovers

—NASA: “Apollo Astronaut Walter Cunningham Dies at 90“

Former astronaut Walter Cunningham, who flew into space on Apollo 7, the first flight with crew in NASA’s Apollo Program, died early Tuesday morning in Houston. He was 90 years old. “Walt Cunningham was a fighter pilot, physicist, and an entrepreneur – but, above all, he was an explorer. On Apollo 7, the first launch of a crewed Apollo mission, Walt and his crewmates made history, paving the way for the Artemis Generation we see today,” said NASA Administrator Bill Nelson. “NASA will always remember his contributions to our nation’s space program and sends our condolences to the Cunningham family.”

—New Atlas: “Curiosity Finds Opal on Mars – a Possible Water Source for Astronauts“

NASA’s Curiosity rover has discovered opal on Mars. The deposits may prove to be valuable to future Martian explorers not as jewelry but as a potential source of water. Opal is formed when water weathers silica-rich rocks, forming a solution that settles into cracks and crevices in the rock. Over time, this solution hardens into a solid lump that can be cloudy and dull or a dazzling display of color. Most supplies come from either Australia or Ethiopia, but now a new source has been discovered – Mars.

—Space.com: “Juno Spacecraft Recovering its Memory After Mind-blowing Jupiter Flyby, NASA Says“

NASA’s Juno probe is continuing to recover its memory at Jupiter after a data disruption interrupted communications between the spacecraft and its operators on Earth following a flyby of the giant planet in December. The Juno spacecraft’s latest flyby of Jupiter, its 47th close pass of the planet, was completed on Dec. 14. But as its operators at NASA’s Jet Propulsion Laboratory were receiving science data from the flyby they found they could no longer directly access the spacecraft’s memory. The team successfully rebooted Juno’s computer and on Dec. 17 they placed the spacecraft into “safe mode” with only essential systems operating as a precaution. 

Gift Ideas: Glowing Stars, Planets, and Moons

If you are looking for a fun gift that will encourage kids to learn more about the universe around them, then you cannot go wrong with a nightlight that illustrates the beauty of the nighttime objects above us. For instance, the Moon lamp shown above (there are many others like it on Amazon and elsewhere) allows an up-close view of this amazing orb. As with the Earth globes of old, seeing a world in three-dimensions and being able to touch it assists with understanding. Besides, in the case of the Moon, a youngster looking out the bedroom window will only see one side of the Moon, whereas the lamp provides the entire surface.

You can find similar lamps and nightlights showing Mars, Jupiter, and even the Milky Way (see below).

Or why not simply project the constellations onto the bedroom ceiling so kids can learn about the night sky even when it is cloudy outside? There is nothing like a personal planetarium.

Mind you, these gifts are not only for children, but it’s a good place to start. I may yet get one of those Moon lamps for my desk. Why should the kids have all the fun?

A Day in Astronomy: Visit to Asteroid Gaspra

On this day in 1991, NASA’s Galileo spacecraft flew by asteroid Gaspra, which is located in the asteroid belt between Mars and Jupiter. Galileo conducted a quick fly-by while flying towards Jupiter and its moons. The spacecraft also visited the asteroid Ida.

Asteroid Gasprawas first discovered back in 1916 by Russian astronomer G. N. Neujmin, who decided to name it after the Black Sea retreat of Gaspra, a Ukrainian spa town currently occupied by the Russians.

Here is some additional information from NASA about the asteroid, which has similar features to the asteroids now serving as moons to Mars (Phobos and Deimos):

A striking feature of Gaspra’s surface is the abundance of small craters. More than 600 craters, 100-500 meters (330-1650 feet) in diameter are visible here. The number of such small craters compared to larger ones is much greater for Gaspra than for previously studied bodies of comparable size such as the satellites of Mars. Gaspra’s very irregular shape suggests that the asteroid was derived from a larger body by nearly catastrophic collisions. Consistent with such a history is the prominence of groove-like linear features, believed to be related to fractures. These linear depressions, 100-300 meters wide and tens of meters deep, are in two crossing groups with slightly different morphology, one group wider and more pitted than the other. Grooves had previously been seen only on Mars’s moon Phobos, but were predicted for asteroids as well.
