The Washington Post reports NOAA researchers collected and analyzed particles in the stratosphere that indicates the presence of rare elemental metals niobium and hafnium, which “are common in spacecraft manufacturing and can be found in semiconductors, rocket chambers and other applications.” The discovery “sheds light on the environmental aftermath of a growing number of rockets, satellites and other human-made spacecraft that give off metal vapors as they reenter the atmosphere.” The researchers also “identified aluminum, lithium, copper and lead in the stratosphere – all of which are linked to alloys used by the aerospace industry.” It is still unclear “how the existence of these rare metals and other elements in the stratosphere might influence the climate.”

GOES-T Satellite Launched Tuesday
The Washington Post reports on Tuesday, the United States launched “its latest and greatest weather satellite, which will provide constant monitoring over the Western Hemisphere and help track fires, hurricanes, lightning, smoke plumes, coastal fog, landslides, atmospheric rivers, dust storms and more.” Some instruments will also “stare at the sun, providing data on incoming space weather that could disrupt technology on Earth.” The NOAA GOES-T launched “at 4:38 p.m. Eastern from Cape Canaveral Space Force Station in Florida.” The satellite is expected “to be fully operational by early 2023 and will oversee the U.S. West, Alaska, Hawaii, Mexico, Central America and Pacific Ocean.” Pam Sullivan, system program director for the GOES-R Series Program, said in a virtual news conference, “NOAA’s geostationary satellites provide the only continuous coverage of weather and hazardous environmental conditions in the Western Hemisphere, protecting the lives and properties of the 1 billion people who live and work there.”

NOAA to Move GOES into Position Over Western United States
Space News reports that the National Oceanic and Atmospheric Administration (NOAA) “will move its next Geostationary Operational Environmental Satellite (GOES) weather satellite into position over the Western United States soon after launch to speed up data delivery to the National Weather Service.” After the GOES-18 satellite is deployed into geostationary transfer orbit, “the satellite will spend about three weeks moving to geostationary orbit.”

NOAA Releases First Imagery from GOES-18
Spaceflight Now reports that NOAA has “released the first imagery from the new GOES-18 weather satellite that launched March 1 from Cape Canaveral, and confirmed the spacecraft’s main camera doesn’t suffer the same cooling system problem that caused degraded vision in an earlier satellite.” The images were captured “May 5 from a position in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. GOES 18’s primary camera, called the Advanced Baseline Imager, recorded the views in 16 channels, each tuned to see clouds, dust, smoke, and water vapor in different wavelengths of light.”
