NASA granted the NEAR Shoemaker mission a last-minute reprieve Wednesday, extending the mission by up to ten days to give scientists time to capitalize on a surprisingly successful landing on the surface of the asteroid Eros.
NEAR Shoemaker’s Historic Landing on Eros Exceeds Science, Engineering Expectations
The NEAR Shoemaker spacecraft’s historic soft landing on asteroid 433 Eros Feb. 12 turned out to be a mission planner’s dream – providing NEAR team members with more scientific and engineering information than they ever expected from the carefully designed…
NEAR Shoemaker Ready to Gather Data on Surface of Eros
The NEAR Shoemaker spacecraft has been commanded to begin collecting data from the surface of 433 Eros.
Dust and the Canary Islands
Major dust storms are a frequent occurence over northwest Africa andthe Sahara Desert. This image of a massive dust storm was aquired on February11, 2001 by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS). SeaWiFS has seensimilar storms every year since its…
NEAR Shoemaker Still Talking from Surface of Eros
A day after its gentle touchdown on the surface of an asteroid – a deep-space first – the NEAR Shoemaker spacecraft is still communicating with the NEAR team at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, MD.
JPL Navigators Guide NEAR to Historic Landing on Asteroid Eros
With fingers flying across calculator keypads as new guidance data flowed in, JPL space navigators yesterday used fast math, and lots of it, to help carefully nudge NASA’s NEAR Shoemaker spacecraft to its historic touchdown on the surface of asteroid…
Barringer Meteor Crater, Arizona
Barringer Crater, also known as “Meteor Crater,” is a 1,300-meter (0.8mile) diameter, 174-meter (570-feet) deep hole in the flat-lying desertsandstones 30 kilometers (18.6 miles) west of Winslow, Arizona. Sincethe 1890s geologic studies here played a leading role in developing anunderstanding…
Popocatepetl Heats Up
From its space-based perspective aboard NASA’s Terra satellite, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was watching as Popocatepetl awoke from its slumber late last year. Using a combination of its visible and near-infrared channels, ASTER acquired this…
Significant Event Report for Week Ending 2/9/2001
Cassini Significant Event Report For Week Ending 02/09/01 The most recent spacecraft telemetry was acquired from the Goldstone tracking station on Tuesday, February 6. The Cassini spacecraft is in an excellent state of health and is operating normally. The speed…
Alfred Wegener
Alfred Wegener proposed the theory of continental drift – the idea that the Earth’s continents move over hundreds of millions of years of geologic time – long before the idea was commonly accepted.
Mouth of the Amazon
Flowing more than 6,450 kilometers (4,000 miles) eastward across Brazil, the Amazon Riveroriginates in the Peruvian Andes as tiny mountain streams that eventually combine to form one of the world’s mightiest rivers. This image of the Amazon’s mouth was captured…
See What NASA’s Hubble Sees, with the Click of a Mouse
Each day, NASA’s Hubble Space Telescope collects enough information and images to fill five encyclopedias. Now, anyone with access to a computer and the World Wide Web can see the most exciting pictures captured by the world’s first space-based optical…
Fires in Southeastern U.S.
Quite a number of smoke plumes were visible from orbit on Monday, February 5, 2001, as can be seen in this Sea-viewing Wide Field-of-view Sensor (SeaWiFS) image of the southeastern United States. Gauging from this perspective, the OrbView-2 satellite was…
