After the trajectory correction maneuver on October 22, Rosetta has lined up on a near-perfect Earth approach path. The maneuver was so precise that mission controllers decided not to use the additional maneuver slot that was available yesterday. Rosetta's orbit has been determined using radiometric data received from ESA and NASA ground stations, and estimates now show that she will pass within a few kilometers of the planned point of closest approach during next week's Earth swingby. If...

WASHINGTON, Sept. 23 /PRNewswire-USNewswire/ -- NASA's Mercury Surface, Space Environment, Geochemistry, and Ranging spacecraft known as MESSENGER will fly by Mercury for the third and final time on Sept. 29. The spacecraft will pass less than 142 miles above the planet's rocky surface for a final gravity assist that will enable it to enter Mercury's orbit in 2011. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO ) Determining the composition of Mercury's surface is a...

NASA's Mercury Surface, Space Environment, Geochemistry, and Ranging spacecraft known as MESSENGER will fly by Mercury for the third and final time on Sept. 29. The spacecraft will pass less than 142 miles above the planet's rocky surface for a final gravity assist that will enable it to enter Mercury's orbit in 2011. Determining the composition of Mercury's surface is a major goal of the orbital phase of the mission. The spacecraft already has imaged more than 90 percent of the planet's...

In less than two weeks, on September 29, MESSENGER will fly by Mercury for the third and final time, a maneuver key to placing the probe on a trajectory that will enable its March 2011 insertion into orbit about Mercury. Even as the team readies for this critical event, a parallel effort has long been underway to prepare MESSENGER for the main event. Since January, the team has been staging orbital operations rehearsal tests, called week-in-the-life (WITL) tests, to try out the new procedures...

The U.S. space agency says its Dawn spacecraft has re-ignited its ion propulsion system, continuing its eight-year mission to explore the asteroid belt. Mission controllers at the National Aeronautics and Space Administration's Jet Propulsion Laboratory in Pasadena, Calif., said they received a transmission from the Dawn spacecraft confirming the re-ignition. During the eight years Dawn's three ion engines will accumulate 2,000 days of operation. The spacecraft's mission includes...

After a perfect injection by the Ariane 5 launcher on May 14, the critical Launch and Early Orbit Phase (LEOP) for Herschel and Planck has started to wind down, while commissioning of the scientific instruments and subsystems on both spacecraft has begun. Herschel and Planck are functioning nominally and are now en route to their final orbits around the second Lagrange point of the Sun-Earth system (L2), a point in space 1.5 million kms from Earth on the night-side.  The additional...

European scientists hope a proposed mission to capture pieces of an asteroid will shed light on how our Solar System evolved. In the so-called Marco Polo mission, scientists and engineers intend to send a spacecraft to a small nearby asteroid to collect dust and rubble that will be studied to determine how the Solar System came into being. Some speculate the mission could launch sometime in the next decade, in about 2017. Ultimately it is up to the European Space Agency (ESA) to approve the...

Spacecraft controllers have just awoken Rosetta from hibernation to prepare for its encounter with asteroid (2867) Steins on September 5. ESA's comet chaser will study the relatively rare asteroid as it flies by on its way to comet 67/P Churyumov-Gerasimenko. Launched in March 2004, Rosetta will reach its final destination only in 2014, after travelling a total of about 6500 million km. The distance between the spacecraft and the Sun as it approaches the comet will be about 600 million...

After its successful launch by a Soyuz Rocket from Baikonur on 27 April and accurate insertion into its target orbit by the Fregat autonomous upper stage, GIOVE-B is now completing its Launch and Early Operations Phase (LEOP), which will shortly give way to the platform commissioning phase.Platform commissioning includes the on-board verification of all primary and redundant platform subsystems, namely telemetry and telecommand, propulsion, power, thermal control, and attitude and orbit...

Asteroids are Earth's closest celestial neighbors, sometimes passing closer to Earth than even the Moon. And yet, to date, only two spacecraft have ever remained in proximity to one of these bodies. Last month, orbit mechanics experts from around the world met to discuss methods for finding the best possible spacecraft trajectory, or flight path, for visiting a sequence of asteroids. The gathering was part of the second Global Trajectory Optimisation Competition, organized by JPL. The idea...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...
