Cassini Image Mosaic: A Farewell To Saturn

After more than 13 years at Saturn, and with its fate sealed, NASA’s Cassini spacecraft bid farewell to the Saturnian system by firing the shutters of its wide-angle camera and capturing this last, full mosaic of Saturn and its rings two days before the spacecraft’s dramatic plunge into the planet’s atmosphere.

November 21, 2017 – In a fitting farewell to the planet that had been its home for over 13 years, the Cassini spacecraft took one last, lingering look at Saturn and its splendid rings during the final leg of its journey and snapped a series of images that has been assembled into a new mosaic.

NASA’s James Webb Space Telescope Completes Final Cryogenic Testing

NASA’s James Webb Space Telescope sits inside Chamber A at NASA’s Johnson Space Center in Houston after having completed its cryogenic testing on Nov. 18, 2017. This marked the telescope’s final cryogenic testing, and it ensured the observatory is ready for the frigid, airless environment of space. Image Credit: NASA/Chris Gunn

November 21, 2017 – The vault-like, 40-foot diameter, 40-ton door of Chamber A at NASA’s Johnson Space Center in Houston was unsealed on November 18, signaling the end of cryogenic testing for NASA’s James Webb Space Telescope. Read More


NASA’s TSIS-1 Keeps An Eye On Sun’s Power Over Ozone

TSIS-1 will be affixed to the International Space Station in December 2017 TSIS-1 operates like a sun flower: it follows the Sun, from the ISS sunrise to its sunset, which happens every 90 minutes. At sunset, it rewinds, recalibrates and waits for the next sunset. Image Credit: NASA/LASP

November 21, 2017 – High in the atmosphere, above weather systems, is a layer of ozone gas. Ozone is Earth’s natural sunscreen, absorbing the Sun’s most harmful ultraviolet radiation and protecting living things below. But ozone is vulnerable to certain gases made by humans that reach the upper atmosphere. Once there, they react in the presence of sunlight to destroy ozone molecules. Read More

Drone racing is a high-speed sport demanding instinctive reflexes — but humans won’t be the only competitors for long. Researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, put their work to the test recently. Timing laps through a twisting obstacle course, they raced drones controlled by artificial intelligence (A.I.) against a professional human pilot.

The National Oceanic and Atmospheric Administration’s Joint Polar Satellite System-1 (JPSS-1) blasted off the launchpad at Vandenberg Air Force Base on the central California coast 1:47 a.m. PST (4:47 a.m. EST) Saturday, Nov. 18. On the NOAA satellite were five science instruments, including the Clouds and the Earth’s Radiant Energy System Flight Model 6 (CERES FM6), a NASA instrument that measures the solar energy reflected by Earth, the heat the planet emits, and the role of clouds in that process.
