NASA's newest spacecraft at Mars has already cut the size and duration of each orbit by more than half, just 11 weeks into a 23-week process of shrinking its orbit. By other indicators, the lion's share of the job lies ahead. "The orbits are getting shorter and shorter. We've finished about 80 of them so far, but we have about 400 more to go, and the pace really quickens toward the end," said Dan Johnston, Mars Reconnaissance Orbiter deputy mission manager at NASA's Jet Propulsion...

Researchers today released the first Mars images from two of the three science cameras on NASA's Mars Reconnaissance Orbiter. Images taken by the orbiter's Context Camera and Mars Color Imager during the first tests of those instruments at Mars confirm the performance capability of the cameras. The test images were taken from nearly 10 times as far from the planet as the spacecraft will be once it finishes reshaping its orbit. Test images from the third camera of the science payload were...

NASA's Mars Reconnaissance Orbiter yesterday began a crucial six-month campaign to gradually shrink its orbit into the best geometry for the mission's science work. Three weeks after successfully entering orbit around Mars, the spacecraft is in a phase called "aerobraking." This process uses friction with the tenuous upper atmosphere to transform a very elongated 35-hour orbit to the nearly circular two-hour orbit needed for the mission's science observations. The orbiter has been flying...

JPL -- The first test images of Mars from NASA's newest spacecraft provide a tantalizing preview of what the orbiter will reveal when its main science mission begins next fall. Three cameras on NASA's Mars Reconnaissance Orbiter were pointed at Mars at 8:36 p.m. PST Thursday, while the spacecraft collected 40 minutes of engineering test data. The cameras are the High Resolution Imaging Science Experiment, the Context Camera and the Mars Color Imager. "These high-resolution images of Mars...

WUSTL -- Two Mars orbiter missions - one from NASA, the other from the European Space Agency (ESA) - will open new vistas in the exploration of Mars through the use of sophisticated ground-penetrating radars, providing international researchers with the first direct clues about the Red Planet's subsurface structure. Roger Phillips, Ph.D., Washington University in St. Louis Professor of Earth and Planetary Sciences in Arts & Sciences, is participating in both the Mars Express (ESA) and...

By Deborah Zabarenko WASHINGTON -- NASA's Mars Reconnaissance Orbiter is headed into a perilous phase after a seven-month journey from Earth, aiming to start looping around the Red Planet on March 10, space agency officials said on Friday. If it manages to reach its planned orbit, a process that will take another seven months, the spacecraft could collect unprecedented data about Earth's next-door planetary neighbor, which could help scientists determine where to land the next Mars rovers and...
