NASA, SpaceX Target New Launch Date for NOAA Weather Satellite

NASA and SpaceX now are targeting Tuesday, June 25, for the launch of GOES-U, the fourth and final satellite in National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellites (GOES) – R Series. The new launch date allowed time for teams to fully repair and test the Falcon Heavy core booster after a liquid oxygen leak was identified during routine new booster testing in February. NASA and SpaceX teams have resumed preparation of the GOES-U launch. GOES-U will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.

NOAA oversees the GOES-R Series Program through an integrated NOAA-NASA office, managing the ground system, operating the satellites, and distributing their data to users worldwide. NASA’s Goddard Space Flight Center manages the acquisition of the spacecraft and instruments and also built the Magnetometer instrument for GOES-T and GOES-U. NASA’s Launch Services Program, based at Kennedy Space Center manages the launch services for the GOES missions. Lockheed Martin designs, builds, and tests the GOES-R series satellites. L3Harris Technologies provides the primary instrument, the Advanced Baseline Imager, along with the ground system, which includes the antenna system for data reception.

NASA and SpaceX are now targeting no earlier than May 2024 for the launch of the fourth and final satellite in NOAA’s Geostationary Operational Environmental Satellites (GOES) – R Series, GOES-U. The new date allows for additional testing and preparation of a new Falcon Heavy center core booster after a liquid oxygen leak was discovered during routine new booster testing.

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, tornadoes, fog, hurricanes, flash floods and other severe weather.

In addition, GOES observations have proven helpful in monitoring dust storms, volcanic eruptions, and forest fires.

“That is what it’s all about – when we get to the spacecraft separation. It’s years of work going into that one event,” said NASA Launch Director Tim Dunn. “Today, we were blessed with a smooth and successful countdown.”

A joint effort between NASA and NOAA, GOES-T will be renamed GOES-18 once it reaches geostationary orbit, replacing GOES-17 as GOES West. It will be positioned to watch over the western contiguous United States, Alaska, Hawaii, Mexico, Central America, and the Pacific Ocean. The satellite will be ideally located to monitor weather systems and hazards that most affect this region of the Western Hemisphere.

GOES-T is about the size of a small school bus and weighs more than 6,000 pounds. Liftoff, aboard a United Launch Alliance Atlas V 541 rocket from Cape Canaveral Space Force Station’s Space Launch Complex 41 in Florida, occurred right at the top of the two-hour launch window, at 4:38 p.m. EST. All milestones were successfully reached – from liftoff through spacecraft separation.

The launch was managed by NASA’s Launch Services Program, based at NASA’s Kennedy Space Center in Florida.

Main Engine Restart, Cutoff Executed

GOES-T mission logo 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.

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 interesting fact to throw in while we announce main engine cutoff (MECO) has occurred and the first stage has separated from the rocket. Coming up next, in about 10 minutes, will be Centaur main engine start #2, followed by main engine cutoff #2 about five minutes later.

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 right here on the blog, or tune in to NASA TV, the NASA app, or the agency’s website to watch the spacecraft and rocket eclipse more launch milestones. Live coverage continues through GOES-T spacecraft separation at approximately 8:30 this evening. The next milestone is main engine cutoff, or MECO, coming in about 10 minutes.

Weather Outlook Solid, GOES-T on Target for 4:38 p.m. EST Launch

GOES-T mission logo 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.
