It's been an exciting couple weeks for the exploration of planets around other stars.

A new report reveals that Barnard's star (closest single star to the Sun) has a whole system of planets.

People have been seeking planets there since the '60s. Now we've found them--four rocky worlds, 1/4 the mass of Earth, in tight orbits around their tiny red star.

This animation shows the orbital dynamics of the Barnard’s Star planetary system. For a century, astronomers have been studying Barnard’s Star in the hope of finding planets around it. First discovered by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth. Now, using in part the Gemini North telescope, one half of the International Gemini Observatory, partly funded by the U.S. National Science Foundation and operated by NSF NOIRLab, astronomers have discovered four sub-Earth exoplanets orbiting the star. One of the planets is the least massive exoplanet ever discovered using the radial velocity technique, indicating a new benchmark for discovering smaller planets around nearby stars.

#PPOD: Hubble has snapped a spectacular view of M66, the largest "player" of the Leo Triplet, and a galaxy with an unusual anatomy: it displays asymmetric spiral arms and an apparently displaced core. The peculiar anatomy is most likely caused by the gravitational pull of the other two members of the trio.

"F-22 Pilot Swaps in for Guardian at International Space Station" by Air & Space Forces Magazine - Article notes that #NASA#Crew10 pilot Nichole Ayers (Major USAF) arrives at ISS as #Crew9 commander Nick Hague (Colonel USSF) prepares to return to Earth. Each is a member of a crew rotation of 4, with other US military members. The article links these two due to focus on Air Force & Space Force, excluding Army & Navy on the crews. https://www.airandspaceforces.com/f-22-pilot-guardian-international-space-station/ #space #military #aviation #avgeek

“In everyone’s pocket right now is a computer far more powerful than the one we flew on Voyager. I don’t mean your cell phone — I mean the key fob that unlocks your car.”

The long knives are now out for @NASA. It's billed here as "a first step in broader workforce reductions at the agency ordered by the Trump administration."

One of the affected divisions is the Office of Technology, Policy, and Strategy (OTPS), whose intended purpose "was to provide 'data- and evidence-driven technology, policy, and strategy advice' for NASA. It has worked on topics such as space sustainability and space solar power studies."

You don't know Jennifer Herman's name, but you should. She became the lead power subsystem engineer for the Spirit and Opportunity rovers. Her tireless work for months on end is, more than anything else, the reason why our twin girls survived the deadly 2007 Martian dust storms.

And now she's the lead power subsystem engineer for Voyager. In the same quiet, dedicated way, she's the one making the tough calls that'll help keep *them* alive for years to come.

Tomorrow could be a great day for space robots.

Intuitive Machines' Athena lander is set to touch down on the Moon carrying the "Grace" Hopper robot, Yaoki 360° rover, and MAPP prospecting rover.

Plus a micro-rover, AstroAnt, that will ride around on top of the MAPP rover!

https://www.intuitivemachines.com/im-2 #space #science #nasa #tech

The AstroAnt robot will be operating on the top surface of the Lunar Outpost MAPP-1 rover, equipped with a thermopile on its bottom surface for contact-less temperature measurements of the MAPP-1 rover radiator. With mobility in the Lunar gravity environment, the robot can measure temperature from different positions on the radiator and help with monitoring the performance of the thermal system, which is one of the most crucial systems of the rover. Leveraging magnetic wheels, the robot can attach to and move along the top rover surface. The AstroAnt will be the first-ever miniature robotic mission on the Lunar surface.

#PPOD: NASA’s Curiosity Mars rover spotted these finger-like rocks with its Mast Camera, or Mastcam, on May 15, 2022, the mission's 3,474th Martian day, or sol. These rocks likely formed as groundwater trickled through rock in the ancient past, depositing mineral cements over time. When the rock was exposed to the atmosphere many years later, wind eroded the softer material around the cemented portions. Credit: NASA/JPL-Caltech/MSSS

Blue Ghost is on the Moon! Images are coming in now from what appears to be the first fully successful commercial lunar lander. Just look at that shadow.

Over the next 2 weeks, Firefly's Blue Ghost will drill, study lunar dust, and observe an eclipse of the Sun...by the Earth.
