Astronaut Matthew Dominick speaks with media representatives prior to the Green Run hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket at Stennis Space Center near Bay St. Louis, Mississippi, on Saturday, January 16, 2021. NASA conducted a hot fire test of the core stage’s four RS-25 engines on the B-2 Test Stand at Stennis. Scheduled for as long as eight minutes, the engines fired for a little more than one minute to generate a combined 1.6 million pounds of thrust, just as will occur during an actual launch. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the SLS core stage prior to launching the Artemis I mission to the Moon.

iss071e170351 (6/3/2024) --- NASA astronaut Matthew Dominick captured red sprites from space station. The bright red flashes in the center of this image are a little-understood phenomenon associated with powerful lightning events and appear high above the clouds in Earth’s upper atmosphere. Red sprites are one type of Transient Luminous Events, colorful bursts of energy that appear above storms due to lightning activity occurring in and below storms on Earth. Understanding processes occurring in Earth’s atmosphere can help improve climate modeling and monitoring.
