It is clear to everyone that astronomy at all events compels the soul to look upwards, and draws it from the things of this world to the other.

Farewell, Gaia! Spacecraft operations come to an end

ESO Top News - Thu, 03/27/2025 - 6:00am

The European Space Agency (ESA) has powered down its Gaia spacecraft after more than a decade spent gathering data that are now being used to unravel the secrets of our home galaxy.

On 27 March 2025, Gaia’s control team at ESA’s European Space Operations Centre carefully switched off the spacecraft’s subsystems and sent it into a ‘retirement orbit’ around the Sun.

Though the spacecraft’s operations are now over, the scientific exploitation of Gaia’s data has just begun.

Long-chain Hydrocarbons Found on Mars

Universe Today - Wed, 03/26/2025 - 11:07pm

The search for evidence of life on Mars just got a little more interesting with the discovery of large organic molecules in a rock sample. The Mars Curiosity Rover, which is digging in the Martian rock beds as it goes along, tested pieces of its haul and found interesting organic compounds inside them.

Sols 4491-4492: Classic Field Geology Pose

NASA - Breaking News - Wed, 03/26/2025 - 8:08pm
Curiosity Navigation

2 min read

Sols 4491-4492: Classic Field Geology Pose NASA’s Mars rover Curiosity acquired this image using its Front Hazard Avoidance Camera (Front Hazcam), showing the rover’s right-front wheel perched on a small, angular block, where it ended its weekend drive of about 75 feet (23 meters). In the interest of stability, the Curiosity team prefers to have all six rover wheels on the ground before deploying its 7-foot-long robotic arm (2.1 meters), so they opted for remote sensing observations instead, then another drive higher in the canyon. Curiosity captured this image on March 23, 2025 — sol 4489, or Martian day 4,489 of the Mars Science Laboratory mission — at 15:24:49 UTC. NASA/JPL-Caltech

Written by Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center

Earth planning date: Monday, March 24, 2025

If you’ve ever seen a geologist in the field, you may have seen a classic stance: one leg propped up on a rock, knee bent, head down looking at the rocks at their feet, and arm pointing to the distant stratigraphy. Today Curiosity decided to give us her best field geologist impression. The weekend drive went well and the rover traversed about 23 meters (about 75 feet), but ended with the right front wheel perched on an angular block. In the Front Hazcam image above, you can see the right front wheel on a small block, and the rover’s shadow with the mast staring out at all the exciting rocks to explore. Great pose, but not what we want for planning contact science! We like to have all six wheels on the ground for stability before deploying the robotic arm. So instead of planning contact science today, the team pivoted to a lot of remote sensing observations and another drive to climb higher in this canyon.

I was on shift as Long Term Planner today, and it was fun to see the team quickly adapt to the change in plans. Today’s two-sol plan includes targeted remote sensing and a drive on the first sol, followed by an untargeted science block on the second sol.
On Sol 4491, ChemCam will acquire a LIBS observation of a well-laminated block in our workspace named “Big Narrows,” followed by long-distance RMI observations coordinated with Mastcam to assess an interesting debris field at “Torote Bowl.” The team planned a large Mastcam mosaic to characterize the stratigraphy at Texoli butte from a different viewing geometry than we have previously captured. Mastcam will also be used to investigate active surface processes in the sandy troughs nearby, and an interesting fracture pattern at “Bronson Cave.” Then Curiosity will drive further to the south and take post-drive imaging to prepare for the next plan. On the second sol the team added an autonomously selected ChemCam AEGIS target, along with Navcam movies to monitor clouds, wind direction, and dust.

Keep on roving Curiosity, and please watch your step!

One Day We Might Seed the Universe With Life. But Should We?

Universe Today - Wed, 03/26/2025 - 6:06pm

Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will explode and irradiate all life, a black hole will engulf the Earth, a Mars-sized interstellar asteroid with our name on it. A cataclysm that will end all life on Earth. We could accept our fate and face our ultimate extinction together. We could gather the archives from libraries across the world and launch them into space in the hopes that another civilization will find them. Or we could build a fleet of arks containing life from Earth. Not people, but bacteria, fungi and other simple organisms. Seed the Universe with our genetic heritage. Of all of these, the last option has the greatest chance of continuing our story. It's an idea known as directed panspermia, and we will soon have the ability to undertake it. But should we?
