Just a thirty-something year old science nerd with a few cats lol oh and I like the Hellaverse





Booster 19 rolls out to the pad for its second static fire campaign ahead of Starship Flight 12. This booster is now sporting a fresh coat of black paint and appears flight-ready! @NASASpaceflight



Artemis III orbit type confirmed, @NASA wants new commercial comms system for Live 4K Video COMMUNICATIONS As Orion is designed to fly into deep space, it's designed to rely the Deep Space Network (DSN). That's not available in LEO, and TDRSS is already congested. @NASA would like "live 4K imagery during rendezvous and docking operations, and downlink of large files in other phases of flight." A new request for information (RFI) has just been released, looking for a commercial solution with the following objectives: - Near continuous communication (goal: >75%) - >12 Mbps Downlink (goal: 20-50Mbps) - >500 kbps Uplink - System must provide a broad field of regard or steerable antenna/aperture (Orion has many driving attitude constraints so precise vehicle pointing of a fixed antenna/aperture is not available) I wonder who has a flight-proven, self-steering, on-orbit system for high-bandwidth communications... cough cough @SpaceX @Starlink OTHER DETAILS The RFI says to assume a Summer 2027 launch, and a 460km (250nmi) circular 33° orbit. @NASA had been deciding between a High Earth Orbit (HEO) and Low Earth Orbit (LEO), and it looks like the latter has been selected. A LEO probably doesn't require the use of an upper stage, saving an ICPS. 📷 L: @NASA | R: @SpaceX





One question I get a lot is can you see the stars differently from up in space. When we orbit on the night side of the planet, we get a view of the stars very much like being in a very dark place on Earth. And because of our orbital inclination, we get to see the stars of both the northern and southern hemisphere. I captured this shot of our galactic plane from one of the windows of the Crew Dragon Freedom that is docked to the zenith docking port.












BREAKING: Starship Flight 12 NET May 12, 22:30 UTC / 17:30 CDT An advisory has appeared on the CADENA Operational Information System. - NEW Trajectory - Afternoon Launch Window The window spans 22:30 - 00:43 UTC, which is 17:30 - 19:43 Starbase local time. Instead of flying the corridor between Florida and Cuba, Starship Flight 12 appears to be targeting a more inclined corridor, threading the needle between Mexico's Yucatán Peninsula, Cuba, the Cayman Islands, Jamaica, Haiti, and the Dominican Republic. Despite this change in launch trajectory, splashdown remains in the Indian Ocean, with a corridor running through Madagascan, Mauritian, and Australian airspace. 🗺️ CADENA Operational Information System Credit to @NeedPizza42 for spotting



Ever since I saw a photo like this in 2018 I wanted to do this. It took me 8 years, but I finally got it.
