Who is excited to send a spacecraft to Europa? Every person I’ve talked to who is even remotely interested in planetary exploration is incredibly enthusiastic about the upcoming Europa Clipper mission to explore Jupiter’s icy moon. With strong evidence of a subsurface liquid ocean, Europa is considered by many to be the most likely place in our Solar System – besides Earth — which might harbor life. The many mysteries about this moon make it a compelling place to explore.

Thanks to Observations, a Potentially Dangerous Asteroid was Found to be Harmless

Earlier this year, the discovery of a potentially hazardous asteroid took astronomers on a roller coaster ride.

On January 6, 2022, astronomers at the Mount Lemmon Observatory in Arizona discovered an asteroid roughly 70-meters (230 ft) across. Based on their initial observations, it appeared this object — called ‘2022 AE1’ – could potentially hit Earth on its next pass, on July 4, 2023.

Stunning Photos from Air, Space and Ground of the Atlas V GOES-T Launch

NASA and NOAA now have a sophisticated new weather satellite in space. The GOES-T satellite launched on the powerful United Launch Alliance (ULA) Atlas V rocket on March 1, and it will provide forecasters with high resolution weather imagery. It will also provide real-time monitoring of events on the ground like wildfires, floods and landslides, while monitoring atmospheric and climate dynamics over the Western US and Pacific Ocean.

The liftoff from Cape Canaveral Space Force Station of GOES-T (Geostationary Operational Environmental Satellite-T) provided stunning views, and incredibly, other satellites looked down and captured the launch of the new satellite from space, such as this shot from its older sibling, GOES-16:

Here’s The Exact Point of the Moon’s South Pole

As the Moon heads into southern summer the region around the south pole is better seen by LROC. One of the many goals of the LRO mission is to improve our cartographic knowledge of the Moon. The location of the pole shown here (image 1600 meters wide) may be in error by several hundred meters, wait a year for an update! [NASA/GSFC/Arizona State University]

Since 2009, the Lunar Reconnaissance Orbiter (LRO) has been taking high-resolution pictures of the lunar surface. This data, along with the information from a laser altimeter mapping instrument has allowed scientists to create an incredibly detailed map of the Moon. NASA says they can now confidently pinpoint any feature on the Moon, including the exact location of its South Pole.

Europe’s ExoMars Rover Will Likely Miss This Year’s Launch Window Because of Russia’s Invasion of Ukraine

As countries around the world respond to Russia’s invasion of Ukraine with sanctions aimed at crippling Moscow and Vladimir Putin, the global cooperation in space exploration that has been forged over the past 30-plus years will certainly be impacted.

New Images of Artemis in the VAB; Rollout for SLS Launch Rehearsal Test Now Scheduled for March 17

Every journey begins with a single step, and the first step of NASA’s return to the Moon begins with a four-mile rollout to the launchpad. NASA announced their target date for rolling out the Space Launch System rocket for the four-mile crawl to the launch pad is March 17. The full rocket stack will spend about a month at the pad undergoing several tests before heading back to the Vehicle Assembly Building. If all goes well with the tests, NASA hopes to launch its uncrewed Artemis test flight, likely by early summer.

Curiosity Finds a Bizarre Rock on Mars that Looks Like a Flower

The Curiosity rover took a picture of something pretty enticing this week on the surface of Mars. While the object in question looks like a tiny little flower or maybe even some type of organic feature, the rover team confirmed this object is a mineral formation, with delicate structures that formed by mineral precipitating from water. The size of this tiny object is just 1 centimeter.

Webb turns those 18 separate star images into a single unified star. Next comes even better focus.

During this phase of alignment known as Image Stacking, individual segment images are moved so they fall precisely at the center of the field to produce one unified image instead of 18. In this image, all 18 segments are on top of each other. After future alignment steps, the image will be even sharper. Credit: NASA/STScI

It’s coming together! Engineers for the James Webb Space Telescope have now completed two more phases of the seven-step, three-month-long mirror alignment process. This week, the team made more adjustments to the mirror segments along with updating the alignment of its secondary mirror. These refinements allowed for all 18 mirror segments to work together — for the first time — to produce one unified image.

Need Some More Ytterbium? Who Doesn’t? Here’s Where you can Find it in Space

Looking to do some mining in space? Need a little Ytterbium on your next flight through the galaxy? Researchers have figured out the best places in the cosmos to find this unusual but useful element.

Chinese Rover Finds Translucent Glass Globules on the Moon

Two confirmed (upper row) and two possible (bottom row) glass globules found along the route of Yutu-2 (Image taken by the Yutu-2 rover; courtesy of China National Space Administration).

Scientists say China’s Yutu-2 rover, part of the Chang’E-4 mission, has found several small glass globules on the Moon’s far side. While tiny glass beads have been found previously in lunar samples brought back by the Apollo astronauts, the ones found by Yutu-2 are much bigger and translucent.

The discovery was made by Dr. Zhiyong Xiao, one of the lead scientific team members of the Chang’E-4 mission. They beads were found by looking at panoramic images taken by the rover. Since the rover doesn’t have sampling capabilities and is not a sample return mission like it’s older sibling, the Chang-E-5 mission, there is no compositional data on the glass beads, only observational evidence.
