Welcome, ORCA38! 🎉
After 4 days of flawless operations at sea, the ORCA detector just got a major upgrade: 5 new detection units installed in the deep sea, bringing the total to 38. A huge thank you to everyone involved, offshore crews and onshore teams, for making this great step forward possible!

Good work! Shows nicely that ONLY the zodiacal light is responsible for the 'glow' behind the Moon with no contribution from the K corona. (Told you so, NASA, from day one.)

Engineers from Katalyst Space Technologies unpack their LINK robotic servicing spacecraft at NASA’s Goddard Space Flight Center in Greenbelt, Md., on April 14, 2026. The satellite will undergo vibration and thermal testing at NASA Goddard ahead of launch later this year. Once in space, LINK will attempt to rendezvous with NASA’s Neil Gehrels Swift Observatory and boost it into a higher orbit. Image Credit: NASA/Sophia Roberts

Testing has begun for the Katalyst-NASA Swift Boost Mission! 🚀 The LINK robotic spacecraft is at NASA Goddard for environmental tests before its launch later this year to give the 21-year-old Swift Observatory a much-needed lift. #NASA #SpaceTech #SwiftBoost

NASA Selects Voyager for Seventh Private Mission to Space Station - NASA NASA and Voyager Technologies have signed an order for the seventh private astronaut mission to the International Space Station, targeted to launch no earlier

NASA has chosen Voyager Technologies for the 7th Private Astronaut Mission (PAM) to the ISS. Axiom Space got the first five, but it's expanding now. Vast got the 6th and now Voyager the 7th. www.nasa.gov/news-release...
Axiom, Vast and Voyager each are developing cmrcl space stations.

Are there legal requirements when the state of the vehicle has to be made public? During the mission it was mentioned that e.g. the early science results from the Moon had to be written up until a not too distant deadline.
