NOAA proposes future geostationary constellation with East, West and Center satellites
Sunday, 10 January 2021 19:50
SAN FRANCISCO – NOAA’s National Satellite, Data and Information Service is recommending flying three satellites over the United States in the satellite constellation that will follow the Geostationary Operational Environmental Satellite R Series (GOES-R).
In addition, to operating satellites in orbits similar to those of the current GOES East and GOES West satellites, NOAA recommends placing a third spacecraft over the center of the United States, Pam Sullivan, GOES-R system program director, said Jan.
Researchers find Mars has a Chandler wobble
Sunday, 10 January 2021 17:50
A combined team of researchers from the Jet Propulsion Laboratory, California Institute of Technology and the Royal Observatory of Belgium, has found evidence that Mars has a Chandler wobble. In their paper published in the journal Geophysical Research Letters, the group describes their study of decades of data from Mars probes and what it showed them.
Approximately a century ago, astronomer Seth Carlo Chandler discovered that imperfectly round objects (such as planets) sometimes spin off their axis for periods of time. The phenomenon has come to be known as the Chandler wobble, and has been documented for planet Earth, which veers from its axis for distances up to 30 feet in a pattern that repeats approximately every 433 days. Researchers have suggested that other planets likely have a Chandler wobble, but until now, it has never been observed because measuring it on the planet scale requires precise measurements over many years. In this new effort, the researchers obtained the right kind of data from space probes that orbited Mars over many years: The Mars Reconnaissance Orbiter, the Mars Global Surveyor and Mars Odyssey.
