by Staff Writers // Pasadena CA (SPX) Mar 10, 2006
[...] 350-million-mile journey - [...] achieve[d] a proper orbit.
[...]
Before the MRO can begin its two-year science mission, however, it must spend nearly seven more months adjusting its instruments and its orbit, using an experimental process called aerobraking.
As explained by Graf, the spacecraft's initial capture by Martian gravity has placed it into an elongated, 35-hour orbit. Then, the spacecraft will use hundreds of guided dips into the upper Martian atmosphere. The maneuvers will apply atmospheric drag to slow the MRO - but not overheat it - and reshape its orbit into a nearly circular, two-hour loop at an altitude of 200 miles (321 kilometers).
This strategy allowed NASA to save 500 kilograms (1,100 lbs.) at launch, but "aerobraking is like a high-wire act in open air," Graf said. The Martian atmosphere can swell rapidly, "so we need to monitor it closely to keep the orbiter at an altitude that is effective and safe."
The orbiter is carrying six instruments to study Mars from its subsurface geology to its high thin cloudtops. They include the most powerful telescopic camera ever sent to another planet - it can image rocks the size of a small desk. Those instruments will allow the spacecraft to "return as much information as all previous Mars missions combined," said Michael Meyer, the orbiter's chief scientist.[...]
In addition to the camera, the orbiter carries an advanced mineral mapping instrument called PRISM, which can handle 600 channels of spectrographic information and can identify water-related deposits in areas as small as a baseball infield. Its 30-foot radar antenna will probe for ice and water buried as deep as a half-mile below the surface. Its weather camera will monitor the entire planet daily, and its infrared Climate Sounder will monitor atmospheric temperatures and the movement of water vapor.
In all, the MRO represents an extension of all of NASA's planetary exploration capabilities, including - after it finishes its science mission - communications relay. "The instrumentation is unprecedented," Meyer said, adding that the orbiter can transmit data approximately 10 times faster than any previous Mars craft, and it is expected to return more data than all previous Mars missions combined.
[...]
"We're hoping we can actually image the rovers," he added.

Scientists and engineers are ready to start testing the image-taking
skills of the newest spacecraft to swing into orbit around Mars.
NASA’s Mars Reconnaissance Orbiter (MRO) is in great shape after
its arrival at the planet on March 10. It is now being readied to produce
its first images of Mars this week—using the most powerful telescope
camera ever sent to another planet.
The University of Arizona’s super-powerful High Resolution Imaging Experiment (HiRISE)
camera is scheduled to relay first test shots of Mars on March 23 to the
HiRISE Operations Center at the University of Arizona in Tucson.

Mars Cameras Debut as NASA Craft Adjusts Orbit
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 released previously

MRO: Delicate Dips into the Martian Atmosphere
By Leonard David Senior Space Writer posted: 12 May 2006 03:43 pm ET
NASA’s newest mission to the red planet—the Mars Reconnaissance Orbiter (MRO)—is working well as it shaves off altitude in order to swing into active science-gathering duties later this year.
The initial capture by Mars’ gravity put the spacecraft into a very elongated, 35-hour orbit.
Now underway is the delicate art of “aerobraking”—using hundreds of cautiously calculated dips into the upper atmosphere of Mars. The process uses brief burns from MRO’s thrusters. Those dips have to be deep enough to slow the spacecraft by atmospheric drag … but not deep enough to overheat or damage the orbiter.

Views of HiRISE Imagesquote:MRO Successfully Concludes Aerobraking 30-08-2006
Nearly six months after it entered orbit, Mars Reconnaissance Orbiter has concluded its aerobraking phase. The spacecraft had been dipping in and out of the red planet's atmosphere to adjust its orbit. On August 30, 2006, during its 445th orbit, the spacecraft fired its intermediate thrusters to raise the low point of its orbit and stop dipping into the atmosphere.
The six-minute engine burn began at 10:36 a.m. (PST), altering the spacecraft's course so that its periapsis (the closest it comes to the planet) is about 210 kilometers (130 miles) above the planet, well above the atmosphere.
"Aerobraking has changed the course of the spacecraft from just over 35 hours per orbit to just under two hours per orbit and it has saved us roughly 600 kilograms of fuel," said Dan Johnston, Mars Reconnaissance Orbiter Deputy Mission Manager. "Getting out of aerobraking was a phenomenal moment and everyone on the flight teams has done a fantastic job to get us where we need to be for science acquisition."
The next step for the spacecraft will be two additional orbit adjustments to put the orbiter in the ideal path to begin gathering the most detailed scientific data yet from the red planet. The mission's main science observations are scheduled to begin in November, after a period of transitional deployments and tests, then three weeks of intermittent communications while Mars passes nearly behind the sun.
