NASA is taking steps to potentially roll back the #ArtemisII rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida after overnight Feb. 21 observing interrupted flow of helium to the SLS (Space Launch System) rocket’s interim cryogenic propulsion stage: https://www.nasa.gov/blogs/missions/2026/02/21/nasa-troubleshooting-artemis-ii-rocket-upper-stage-issue-preparing-to-roll-back/ - the upper stage uses helium to maintain the proper environmental conditions for the stage’s engine and to pressurize liquid hydrogen and liquid oxygen propellant tanks; the systems worked during NASA’s Artemis II wet dress rehearsals, but teams were not able to properly flow helium during normal operations and reconfigurations following the wet dress rehearsal that concluded Feb. 19.

The only genuine image of the 2026 annular #SolarEclipse I've seen so far - and at an extremely short wavelength of only 17 nanometers, from the Proba 2 satellite: https://proba2.sidc.be/Eclipse17February2026 (which sees the solar corona in emission, so the Sun doesn't have a sharply defined edge).
