“These three unique missions will help us get to know our Sun and its effects on Earth better than ever before…This knowledge is critical because the Sun’s activity directly impacts our daily lives, from power grids to GPS. These missions will help us ensure the safety and resilience of our interconnected world.”
–Statement by Joe Westlake, Heliophysics Division director at NASA Headquarters, regarding Wednesday’s launch of three missions to investigate the Sun’s influence across the solar system – NASA’s Interstellar Mapping and Acceleration Probe (IMAP), Carruthers Geocorona Observatory, and the National Oceanic and Atmospheric Administration’s Space Weather Follow On-Lagrange 1 (SWFO-L1) missions.

This week’s image is from the NASA/European Space Agency (ESA) Hubble Space Telescope. It shows the odd galaxy NGC 2275 that is hard to describe. Is it an elliptical galaxy, a spiral galaxy, or something else?
NGC 2775 sports a smooth, featureless centre that is devoid of gas, resembling an elliptical galaxy. It also has a dusty ring with patchy star clusters, like a spiral galaxy. Which is it, then: spiral or elliptical — or neither?
Because we can only view NGC 2775 from one angle, it’s difficult to say for sure. Some researchers have classified NGC 2775 as a spiral galaxy because of its feathery ring of stars and dust, while others have classified it as a lenticular galaxy. Lenticular galaxies have features common to both spiral and elliptical galaxies.
It’s not yet known exactly how lenticular galaxies come to be, and they might form in a variety of ways. Lenticular galaxies might be spiral galaxies that have merged with other galaxies, or that have mostly run out of star-forming gas and lost their prominent spiral arms. They also might have started out more similar to elliptical galaxies, then collected gas into a disk around them.
Some evidence suggests that NGC 2775 has merged with other galaxies in the past. Invisible in this Hubble image, NGC 2775 has a tail of hydrogen gas that stretches almost 100 000 light-years around the galaxy. This faint tail could be the remnant of one or more galaxies that wandered too close to NGC 2775 before being stretched apart and absorbed. If NGC 2775 merged with other galaxies in the past, it could explain the galaxy’s strange appearance today.
Nasa has said it hopes to send astronauts on a ten-day trip around the Moon as soon as February. The US space agency had previously committed to launching no later than the end of April but said it aims to bring the mission forward…Artemis Launch Director, Charlie Blackwell-Thompson explained that the powerful rocket system built to take the astronauts to the Moon, the Space Launch System (SLS) was “pretty much stacked and ready to go”. All that remained was to complete the crew capsule, called Orion, connected to SLS and to complete ground tests.
NASA on Monday introduced the 10 people — selected from a pool of 8,000 applicants — who will join the agency’s astronaut corps as it races to return to the moon before attempting an unprecedented crewed mission to Mars. The group includes six women and four men, whom acting NASA Administrator Sean Duffy called “America’s best and brightest.”…This astronaut class marks the first in which there are more women than men, according to NASA.
A large asteroid strike on the Moon could have negative consequences for the artificial satellites we now depend on. That being the case, a NASA-led team has looked into the options for preventing Asteroid 2024 YR4 from making such an impact in 2032. Contrary to the usual conclusions that asteroids should be diverted, not destroyed, they think this is a time for a Hollywood-approved demolition event.

“The HLS schedule is significantly challenged and, in our estimation, could be years late for a 2027 Artemis 3 moon landing.”
-Statement by Aerospace Safety Advisory Panel (ASAP) member Paul Sean Hill, as quoted by Space News. NASA contracted with SpaceX to develop the Human Landing System (HLS) for the astronauts landing on the Moon as part of Artemis III and later missions. While Blue Origin has also been tapped by NASA to assist with later missions, SpaceX was expected to provide the initial HLS. Maybe NASA should have picked two companies to provide the initial HLS, with the second in place still assisting with later landings. The ASAP’s 2024 Annual Report highlighted the many risks related to Artemis III, including several related to the HLS (shown below). Everyone knew this was going to be difficult, and no one wants to be asked to answer “Who Lost the Moon?” Also, it is good we still have a few advisory panels left after the recent purge.

Blue Origin has been selected by NASA to bring the rover to the Moon as part of a $190 million task order under the agency’s Commercial Lunar Payload Services program. Blue Origin’s Blue Moon Mark 1 robotic lander, which is scheduled to land on the Moon later this year, will include the VIPER was part of its future cargo in 2027.
As NASA has noted on its VIPER mission page, the rover was part of the Artemis program:
NASA’s Artemis lunar rover, the Volatiles Investigating Polar Exploration Rover, or VIPER, was designed to explore the relatively nearby but extreme environment of the Moon in search of ice and other potential resources. This mobile robot was slated to land at the South Pole of the Moon on a 100-day mission, in order to teach us about the origin and distribution of water on the Moon and help determine how we can harvest the Moon’s resources for future human space exploration.
While the VIPER mission was cancelled last summer, NASA continued to look for a partner to bring it to the Moon. Fortunately, Blue Origin was already going that way.
This is good news for scientists everywhere. It made no sense to turn a half billion dollar piece of equipment into a museum piece. We need more boots and tires on the lunar surface, and VIPER is fortunately part of those plans again.
