On January 15, 2025, Falcon 9 successfully deployed Firefly Aerospace’s Blue Ghost Mission 1 and ispace’s RESILIENCE lunar landers on a trajectory to the Moon from pad 39A in Florida. For most of our missions, we plan a controlled deorbit of the Falcon second stage so it safely reenters over the ocean. For higher energy missions like those to a lunar transfer orbit, nearly all performance on the vehicle is devoted to successfully placing the payload in the intended orbit, and a controlled disposal maneuver is not always possible. We actively work to be as responsible as possible with hardware left in space to ensure space safety, including for more complex missions. In this case, over time, solar activity and gravity led the second stage toward the Moon. Impacts like this are rare, but they can happen with objects in these types of orbits, and we worked with NASA on the optimal disposal solution. Our focus remains on advancing reliable access to space while working toward even more sustainable operations with Starship in the future. As a fully reusable vehicle, Starship is designed to eliminate expendable upper stages entirely, reducing hardware left in orbit and enabling even more missions to the Moon, Mars, and beyond.

Every second, somewhere across the vast universe, a star reaches its explosive end. Here Hubble views one such supernova fade away in galaxy NGC 2525... (Credit: NASA, ESA, J. DePasquale, M. Kornmesser, M. Zamani, A. Riess (STScI/JHU), SH0ES team, Digitized Sky Survey)

Many have asked how this photo was made. This is my explanation. The ISS rotates about its pitch axis as it orbits Earth at 17,000mph to keep its nadir view constant. Because of this long exposure photography turns stars into arced lines. Sidereal clock drives on Earth match the planet's rotation to see stars clearly. I knew one designed for space could do this too. So a camera mount was custom built at @RITtigers to rotate once every 90 minutes using a 60 to 90 toothed gear system, cancelling out the orbital motion of ISS and allowing the capture of distant stars as fixed points! In essence, it is a a rotational coil spring powered analog star tracker. It was machined out of aluminum and is entirely mechanical to bypass NASA's strict electrical requirements for cargo. We had to get creative! After Expedition 72 it was safely returned to Earth and is to be displayed at RIT. Which I am pleased to say because a similar barn door tracker I made from spare parts on Expedition 6 for nighttime city photography was destroyed in an atmospheric trash disposal! Photography is an important part of sharing the journey to new frontiers for all people of Earth!

NASA recently recognized one of America’s outstanding engineers. At @SpaceX’s Rocket Development Facility in McGregor, Texas, I joined Congressman @PeteSessions and McGregor Mayor Jim Lilley to present Andrew Berkowitz with NASA’s Exceptional Public Achievement Award. Andrew’s pioneering research to better understand liquid methane and oxygen explosions is helping enable the next generation of rockets that will return Americans to the Moon, establish a sustained U.S. presence on the lunar surface, and prepare us for Mars. America’s greatest achievements in space are built by extraordinary people whose work often happens behind the scenes. Andrew’s contributions will help shape the future of exploration for years to come. Congratulations on this well-deserved honor, Andrew, and thank you for your contributions to NASA’s mission and America’s future in space.

The Andromeda galaxy isn't making stars like it used to. A new study using @NASAHubble data shows that star formation in Andromeda has been slowing down over the last 40 million years:

We've finished fueling up our @NASARoman telescope, bringing it one step closer to its targeted liftoff on Aug. 30. Learn more about the process and find out what's next for our mystery-solving mission:

NASA Administrator Jared Isaacman on orbital data centers: "If @elonmusk and SpaceX are betting on this right now, there is no reason to believe this will not come to existence. Never bet against an extremely well capitalized Elon." On NASA's mission to head back to the Moon, he said: "We can't do it without them. So the fact that they're extremely well capitalized right now is a fantastic thing, not to mention the engineering talent that's in there. Without question the greatest entrepreneur and engineer in recent history." via Moonshots pod:
