Good afternoon from Kennedy Space Center in Florida. A United Launch Alliance Atlas V rocket stands ready for liftoff at Space Launch Complex 41 at Cape Canaveral Air Force Station. The Atlas V will carry NOAA’s Geostationary Operational Environmental Satellite-S (GOES-S). Launch is targeted for 5:02 p.m. EST, at the beginning of a two-hour launch …

NOAA’s Geostationary Operational Environmental Satellite-S (GOES-S) is the second in the GOES-R Series of weather satellites that includes GOES-R (now named GOES-16), -S, -T and -U. The GOES-S satellite will be renamed GOES-17 when it reaches geostationary orbit. Once the satellite is declared operational, late this year, it will occupy NOAA’s GOES-West position and provide …

The rocket standing on the pad at Space Launch Complex 41 is an Atlas V 541 configuration, one of the most powerful rockets in the Atlas V fleet. The 541 designation means this rocket has a payload fairing, or nose cone, that is approximately five meters wide, four solid-rocket boosters fastened alongside the central common …
Plant Gravity Perception (PGP): Today the crew removed the Plant Gravity Perception seed cassettes from Experiment Containers (ECs) on the two European Modular Cultivation System (EMCS) rotors and stowed them in a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). They also replaced the ECs on the rotors with ECs for the next Plant …

The latest weather update from meteorologists with the U.S. Air Force 45th Space Wing is now at a 90 percent chance of favorable weather today for liftoff of the Atlas V rocket with NOAA’s GOES-S satellite. The rocket is slated to liftoff at 5:02 p.m. EST.

The United Launch Alliance Atlas V rocket is rolled from the Vertical Integration Facility to the pad at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The launch vehicle will send NOAA’s Geostationary Operational Environmental Satellite (GOES-S) into orbit. The GOES series is designed to significantly improve the detection and observation …

New Horizons is in good health and cruising closer each day to our next encounter, an end-of-the-year flyby of the Kuiper Belt object (KBO) 2014 MU69 (or “MU69” for short). Currently, the spacecraft is hibernating while the mission team plans the MU69 flyby. During hibernation, three of the instruments on New Horizons—SWAP, PEPSSI and SDC—collect …
