About
The Senate Commerce, Science, and Transportation Committee unanimously advanced the NASA Authorization Act of 2026 last week. This bill sets long-term priorities for NASA, authorizing a permanent base on the Moon, reinstating roles for the chief scientist, chief economist, and chief technologist, and supporting STEM education. It extends International Space Station operations to 2032 for a smoother transition to commercial stations and directs continued development of the Nancy Grace Roman Space Telescope while preventing discontinuation of the Chandra X-ray Telescope. The act aligns with revised Artemis plans by canceling Space Launch System upgrades and requires new plans for Mars Sample Return after its prior funding lapse.

NASA nominee Matthew Anderson, testifying before the committee on Thursday in Washington DC, praised the bipartisan support and committed to basic research, hypersonics, space nuclear propulsion, and countering Chinese space advances. The committee plans votes this week on his nomination and Arvind Ramans for NIST director.

In Texas, NASAs Kennedy Space Center teams troubleshooted helium flow issues on the Artemis II Space Launch System rocket inside the Vehicle Assembly Building on February 25. The crawler-transporter 2 then moved it back to Launch Complex 39B for the upcoming crewed flight sending four astronauts around the Moon. NASA announced additions to the Artemis program, shifting Artemis III to 2027 for low Earth orbit tests of systems, life support, communications, propulsion, and new Extravehicular Activity suits with SpaceX and Blue Origin commercial landers, paving the way for an Artemis IV lunar landing in 2028.

The Lunar and Planetary Institute hosted its annual Lunar and Planetary Science Conference this week in Houston, Texas, drawing global experts to discuss lunar samples, planetary formation, and mission data. Meanwhile, NASAs twin ESCAPADE spacecraft, launched November 13, 2025, on Blue Origins New Glenn from Florida, loiter at Sun-Earth Lagrange point 2. They will use Earths gravity in November 2026 for a Mars trajectory, arriving September 2027 to study solar wind stripping the Martian atmosphere.

Intuitive Machines prepares its third Nova C lander mission from Florida in late 2026 on SpaceX Falcon 9, carrying NASA, European Space Agency, and Korea Astronomy and Space Science Institute payloads to the Moon. These efforts reveal a pattern of accelerated US lunar infrastructure via commercial partnerships, Mars atmospheric research, and policy bolstering sustained exploration amid international competition.
