A Field Trip with South Bronx Unite – State of the Planet

The South Bronx is a coastal community without a waterfront. Severed from the shore, two South Bronx neighborhoods—Mott Haven and Port Morris—are saturated with waste facilities, power plants and warehouses, and crisscrossed with highways that carry diesel trucks throughout the community. Local residents experience significantly more asthma hospitalizations that elsewhere in New York City, and children have some of the highest asthma incidence rates in the country.

Organizations like South Bronx Unite seek to bu...

Satellite communications mission brings Space Force to Navy town > United States Space Force > Article Display

EL SEGUNDO, Calif. (AFNS) -- San Diego has long been known for its strong U.S. Navy presence, but many people may not know it’s also home to part of the U.S. Space Force.Space Systems Command’s Narrowband Satellite Communications program office was originally part of the Navy, delivering communications capabilities in the Ultra High Frequency spectrum to support deployments on land, air and sea, with voice services to data networks.On Oct. 1, 2021, the program — including 76 manpower authorizations and 13 satellites — was transferred to the Space Force’s SSC. Since the creation of the USSF as a separate service, space-related capabilities that were previously spread out across the U.S. Department of Defense have been consolidated within the USSF to in...

Fireball lights up the sky over Salt Lake City – NASA Blogs

A bright meteor flew through the skies over northern Utah on Saturday morning, later raining down meteorites over the Great Salt Lake. Residents of the Salt Lake City area were startled by loud booms at 8:30 a.m. MDT on Saturday, Aug. 13, 2022. Eyewitnesses saw a fireball in the sky, 16 times brighter than the full Moon.

Credits: NOAA Approximately 22,000 miles out in space, NOAA’s Geostationary Lightning Mappers (GLM) onboard the Geostationary Operational Environmental Satellites (GOES) 17 and 18 detected the meteor, which was first seen 50 miles over West Valley City. However, it is difficult to pinpoint its exact trajectory. “Daytime fireballs are very tough to analyze,” said Bill Cook...

‘Once-in-a-lifetime event’: rare chance to see explosion on dwarf star 3,000 light years away | Astronomy

In what is being called a “once-in-a-lifetime event”, light from a thermonuclear explosion on a star has been travelling towards Earth for thousands of years and it will be here any day.T Coronae Borealis (also known as T Cor Bor, T CrB, and the Blaze star) will be as bright as the north star (for those in the northern hemisphere).Dr Laura Driessen, from the University of Sydney’s school of physics, said the Blaze star would be as bright as Orion’s right foot for those in the southern hemisphere.A recurrent nova, T CrB becomes visible about every 80 years after a thermonuclear explosion on the surface of a white dwarf about 3,000 light years away.The dwarf sucks up hydrogen from a neighbouring red giant, and that causes a buildup of pressure and heat that eventually triggers the explosion....

Lockheed Martin receives Laser Retroflector Arrays for GPS III SV9, SV10 > United States Space Force > Article Display

EL SEGUNDO, Calif. (AFNS) -- In partnership with NASA and the National Geospatial-Intelligence Agency, the U.S. Space Force GPS III Program Office has delivered two laser retroflector arrays to Lockheed Martin. On May 6, the LRAs were delivered under a directed program to rapidly integrate hosted payloads on GPS satellites ahead of launch call up. The LRAs will be installed onto two GPS III satellites, SV9 and SV10, in preparation for a 2025 launch.The addition of the LRA hosted payload onto GPS satellites marks an expansion of NASA’s Space Geodesy Program space instrument network. The GPS III LRAs will allow NASA to make precise range measurements to the sub-centimeter level using the Satellite Laser Ranging technique, enabling accurate determination...
