Payloads: Electro-static Levitation Furnace (ELF): Tools and materials were gathered, and specific harnesses were disconnected from the Electro-magnetic Laboratory (EML) modules in preparation for Gas Circulation pump removal and replace. The EML is a multi-user facility is designed for containerless materials processing in space. It supports research in the areas of meta-stable states and phases, …
Advanced Physics, Human Research as Crew Readies for Pair of Spacewalks

The seven-member Expedition 66 crew juggled a variety of science experiments on Wednesday including space physics and human research. Four International Space Station astronauts also reviewed procedures for a pair of spacewalks set to begin in less than two weeks. A new experiment on the space station is using artificial intelligence to help process complex …
GOES-T Separates from Spacecraft, Continues on Journey to Save Lives

Following completion of a third planned start and then cutoff of the United Launch Alliance Atlas V 541 Centaur main engine, the National Oceanic and Atmospheric Administration's (NOAA) Geostationary Operational Environmental Satellite-T (GOES-T) satellite separated from the spacecraft and is continuing on its journey to help meteorologists observe and predict local weather events, including thunderstorms, …
Main Engine Restart, Cutoff Executed
The United Launch Alliance Atlas V 541 Centaur main engine successfully restarted and then cut off again just a few minutes later as the GOES-T mission heads into a planned coast phase.
This will last approximately three hours, after which the Centaur main engine will start and then cut off for a third – and final – time.
Check out continuing coverage on NASA TV, the NASA app, or the agency's website. Check back here for a live report on GOES-T's separation from the rocket.
Main Engine Cutoff, First-Stage Separation

Have you ever wondered what the three numbers (541) on United Launch Alliance's Atlas V 541 rocket stand for? The numbers signify a payload fairing, or nose cone, that is approximately 5 meters (16.4 feet) in diameter; 4 solid-rocket boosters fastened alongside the central common core booster; and a 1-engine Centaur upper stage. Just an …
Liftoff! NOAA’s GOES-T Soars Into the Space Coast Sky

3, 2, 1 … LIFTOFF! The National Oceanic and Atmospheric Administration's (NOAA) Geostationary Operational Environmental Satellite-T (GOES-T) satellite spacecraft lights up the late afternoon Florida sky as it roars off the launch pad at Cape Canaveral Space Force Station on a joint effort with NASA to help meteorologists observe and predict local weather events. Stay …
Final ‘Go’ Given for GOES-T Launch

NASA Launch Director Tim Dunn gives the final ‘go' for NOAA's Geostationary Operational Environmental Satellite-T (GOES-T) launch! The skies on Florida's Space Coast soon will be alight as the United Launch Alliance Atlas V 541 rocket's Centaur engines fire up to launch the mission into space.
NOAA’s GOES-T Mission Nears Liftoff

In just about 15 minutes, the United Launch Alliance Atlas V 541 rocket engines will roar to life, sending NOAA's Geostationary Operational Environmental Satellite-T (GOES-T) satellite into space. Excitement is building as the mission nears launch. A joint effort between NASA and NOAA, GOES-T will help meteorologists observe and predict local weather events, including thunderstorms, …
Weather Outlook Solid, GOES-T on Target for 4:38 p.m. EST Launch
The weather outlook for today’s National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellite-T (GOES-T) satellite launch from Cape Canaveral Space Force Station remains positive. Weather officials with the Space Force Station’s 45th Weather Squadron predict an 80% chance of favorable conditions for liftoff from Space Launch Complex 41.
The launch, which is managed by NASA’s Launch Services Program, based at NASA’s Kennedy Space Center, is targeted for 4:38 p.m. EST. There is a two-hour launch window.
“Liftoff winds are going to be our primary concern with a smaller concern coming from some of those passing cumulus clouds,” said Arlena Moses, launch weather officer with the 45th Weather Squadron.
