The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science

Experts found that the White House budget request for the upcoming fiscal year could defund 54 NASA science missions, including a spacecraft currently studying Jupiter and two planned Venus missions: www.scientificamerican.com/article/whit...

For the curious - Artemis II has a total of 28 camera systems, many for internal and external inspection and navigation. Engineering cameras, located on each of Orion’s 4 solar arrays: GoPro HERO4 Black 12 MP Handhelds: Nikon D5 digital SLR 20.8 MP These were selected many years ago. #PlanetSci
