Satellite News

Satellites are used for a large number of purposes. Common types include military (spy) and civilian Earth observation satellites, communication satellites, navigation satellites, weather satellites, and research satellites.

The Hayabusa capsule and bus entered the Earth's atmosphere over Woomera, Australia, on June 13 at 11:21 p.m. local time. From the perspective of NASA's DC-8 airborne observation team, the capsule moved below and slightly ahead of the bus and stayed clear of the spectacular breakup of the bus. After the bus had disintegrated, the capsule continued to create a wake, before reaching peak heating and then fading gradually.

That's when the Japan Aerospace Exploration Agency (JAXA) expects the sample return capsule of the agency's technology demonstrator spacecraft, Hayabusa, to boomerang back to Earth. The capsule, along with its mother ship, visited a near-Earth asteroid, Itokawa, five years ago and has logged about 2 billion kilometers (1.25 billion miles) since its launch in May 2003.

With the return of the Hayabusa capsule, JAXA concluded a remarkable mission of exploration -- one in which NASA scientists and engineers played a contributing role.

"Hayabusa will be the first space mission to have made physical contact with an asteroid and returned to Earth," said Tommy Thompson, NASA's Hayabusa project manager from the Jet Propulsion Laboratory in Pasadena, Calif. "The mission and its team have faced and overcome several challenges over the past seven years. This round-trip journey is a significant space achievement and one which NASA is proud to be part of."
