NASA’s Atmospheric Infrared Sounder (AIRS) instrument observes Hurricane Douglas, Tropical Storm Hanna

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Atmospheric Infrared Sounder (AIRS) was monitoring two storm systems as they took aim at portions of Hawaii and Texas on July 26th. Perched on NASA’s Aqua satellite, AIRS is an instrument that studies Earth’s weather and climate.

As of 11:00am local time, Hurricane Douglas was sweeping toward Hawaii with the potential to directly hit portions of the islands, from Maui to Kauai, in the late afternoon or evening.

NASA to use Asteroid Flyby to test Planetary Defense Network

 

Written by Laurie Cantillo / Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA scientists are excited about the upcoming close flyby of a small asteroid and plan to use its upcoming October close approach to Earth as an opportunity not only for science, but to test NASA’s network of observatories and scientists who work with planetary defense.

The target of all this attention is asteroid 2012 TC4 — a small asteroid estimated to be between 30 and 100 feet (10 and 30 meters) in size. On October 12th, TC4 will safely fly past Earth. Even though scientists cannot yet predict exactly how close it will approach, they are certain it will come no closer than 4,200 miles (6,800 kilometers) from the surface of Earth. The asteroid has been out of range of telescopes since 2012.

NASA reports Small Asteroid 2014 RC to Pass Close, but Safely past Earth

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A small asteroid, designated 2014 RC, will safely pass very close to Earth on Sunday, September 7th, 2014.

At the time of closest approach, based on current calculations to be about 2:18pm EDT (11:18am PDT / 18:18 UTC), the asteroid will be roughly over New Zealand.

From its reflected brightness, astronomers estimate that the asteroid is about 60 feet (20 meters) in size.

This graphic depicts the passage of asteroid 2014 RC past Earth on September 7, 2014. At time of closest approach, the space rock will be about one-tenth the distance from Earth to the moon. Times indicated on the graphic are Universal Time. (NASA/JPL-Caltech)

NASA reports Ten Thousandth Near-Earth Object discovered in Space by Pan-STARRS-1 Telescope

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The 10,000th near-Earth object, asteroid 2013 MZ5, was first detected on the night of June 18th, 2013, by the Pan-STARRS-1 telescope, located on the 10,000-foot (convert) summit of the Haleakala crater on Maui.

More than 10,000 asteroids and comets that can pass near Earth have now been discovered.

Managed by the University of Hawaii, the PanSTARRS survey receives NASA funding.
