Mars Rovers Battle Severe Dust Storm |
|
Whopper dust storms on Mars are whipping up potential problems for the twin Mars rovers, Opportunity and Spirit. Opportunity in particular is getting less power from the sun because it's blocked by a dusty haze. To conserve Opportunity's power supply, engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, have told the rover to conduct only essential operations. Once the storm subsides, the plan is to have Opportunity descend into Victoria Crater, which could be a site of intriguing science discoveries.
Huge dust storms whip around Mars every 5 to 6 years. Scientists hope the rovers will weather this latest storm, and in fact, that they will learn a lot about Martian dust storms from observations made by the rovers, by NASA's orbiting Mars Odyssey and Mars Reconnaissance Orbiter, and by the European Mars Express spacecraft.

MRO Instrument Site Monitors Orbiter's Track |
|
CRISM View is a first-of-its-kind opportunity to watch Mars through the "eyes" of the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) - as if you were riding along with it on the Mars Reconnaissance Orbiter!
The team operating the mineral-mapping camera (CRISM) on NASA's Mars Reconnaissance Orbiter offers Web users a simulated view, in real time, of what part of Mars the instrument is seeing as it orbits the planet. The viewer is based on the application that team members use to monitor their instrument.

Overlooking Opportunity |
|
As engineers and scientists anticipate the Opportunity rover's long-awaited descent into "Victoria Crater," they have a bird's-eye view thanks to the HiRISE (High Resolution Imaging Science Experiment) camera aboard NASA's Mars Reconnaissance Orbiter.
Opportunity's tracks decorate the edge of Victoria Crater like a constellation in our night sky. These tracks represent nearly a year's worth of investigation to characterize the massive depression before deciding whether or not to enter.
Plans are to take a dip into the crater around the second week of July and then proceed down, if driving conditions are favorable.

100 Days of Operations for Mars Reconnaissance Orbiter |
|
The CRISM and HiRISE instruments have given the orbiter's science team and the public much to celebrate as they show us Mars in unprecedented detail.
Less than a year since Mars Reconnaissance Orbiter arrived at Mars and less than four months since its science phase began, instruments aboard the spacecraft are not just sending back stunning images, but making good on the promise to advance our fundamental knowledge of our neighboring planet.
CRISM has looked at recently-formed craters that NASA's champion Mars Global Surveyor mission had imaged over its amazing 10-year journey around Mars. The powerful spectrometer allows scientists to better characterize these impact sites as well as identify specific minerals in and around them. The instrument is also examining areas in the northern plains where NASA's Phoenix scout mission is set to land in May of 2008. It is vital to understand this extremely hostile environment before landing spacecraft there.
Meanwhile, on another part of the instrument deck, the HiRISE camera has been producing images with unprecedented resolution and clarity. Select images have revealed what scientists call "haloes." They believe these are the effects of liquid or gas that flowed through underground rocks on ancient Mars. Since we recognize water as a fundamental part of life as we know it on Earth, any detection of liquid - ancient or recent - on Mars could indicate conditions ripe for microbial life.

NASA Spacecraft Read Layered Clues to Changes on Mars |
|
Studies of recent Martian climate change are on the rise with new data from Mars Reconnaissance Orbiter. Much as scientists study Earth's ice ages through layered deposits, the science team is seeking clues to Mars' past by studying ice-rich layers at the Martian poles. The mineral gypsum and clay minerals found at the poles will be important, as they are indicators of wet conditions on Mars in the past. Radar penetrations that reveal thickness and fine-scale layering will also help define climate variations and environmental conditions on Mars over time.

Mars Like We've Never Seen It!
Even scientists and engineers who are well acquainted with the capability of Mars Reconnaissance Orbiter are in awe of the first images taken from the orbiter's low science orbit. This enhanced-color image from the orbiter's HiRISE (High Resolution Imaging Science Experiment) camera is an example of the beauty and the rich science that this mission promises to deliver.
This shot is just a glimpse of a larger HiRISE image, showing detail of gullies in an unnamed crater in the Terra Sirenum region of Mars. The drastic color differences, courtesy of the camera's high signal to noise ration, allow scientists to "see through shadows," revealing the true nature of martian features.

Mars Mineral Mapper Flips Its Lid |
|
NASA's latest orbiter to visit Mars achieved another mark of success this week. The mineral-mapping instrument on Mars Reconnaissance Orbiter has successfully removed its lens cover and is ready to start observing the planet. This comes on the heels of a successful test of the orbiter's subsurface radar antenna. This period of powering on instruments and completing calibrations leads up to the orbiter's primary science phase, beginning in November 2006.

Mars Reconnaissance Orbiter Adjusts Angle of Orbit |
|
NASA's Mars Reconnaissance Orbiter fired its six intermediate-size thrusters for 210 seconds Tuesday in a maneuver to make the shape of its orbit closer to the planned geometry for the mission's main science phase, beginning in November.
The maneuver raised the portion of the elliptical orbit at which the spacecraft comes nearest to Mars -- the periapsis -- from 216 kilometers (134 miles) above the surface to 320 kilometers (199 miles). A thruster firing on Aug. 30 had lifted the periapsis high enough to end a five-month process of dipping into the atmosphere every orbit to gradually shrink the orbit. The spacecraft now completes each loop around Mars in just under two hours.
The Sept. 5 maneuver also fine-tuned the orbit's angle relative to Mars' equator, tweaking it less than one degree to 92.5 degrees.
A longer firing of the engines next week is planned for lowering the high point of the orbit to make the shape more circular and for locking into a pattern of keeping the periapsis over Mars' South Pole and the far point -- the apoapsis -- over the North Pole.

Mars Reconnaissance Orbiter Successfully Concludes Aerobraking |
|
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.

Mars Reconnaissance Orbiter Continues Aerobraking |
|
NASA's latest orbiter to visit the Red Planet is well into its main phase of aerobraking. Mars Reconnaissance Orbiter has cut about 10 hours off of its initial orbit by strategically dipping in and out of Mars' thin atmosphere.
Now at a 25 hour-orbit, the spacecraft is circling the planet roughly once per martian sol (day), which is 24 hours, 39 minutes.
The periapsis altitude (the closest the spacecraft comes to the planet) of its orbit is at 106 kilometers (66 miles). Periapsis is near 75 degrees south latitude in the South Pole region of Mars.
"The spacecraft will perform a small maneuver tonight (May 10, 2006) that will lower periapsis altitude to 104 kilometers (65 miles)," said Deputy Mission Manager Dan Johnston. "This will allow us to maintain our desired aerobraking orbit period reduction rate. The spacecraft continues to perform very well as we skim through the martian atmosphere."

Next Phase: Aerobraking |
|
After a nearly flawless entry into martian orbit, what is next for Mars Reconnaissance Orbiter? Six months of precise aerobraking will position the spacecraft for optimal science return.
Aerobraking is a process in which engineers utilize the martian atmosphere to slow their craft and ease it into a circular orbit. Initially, the spacecraft entered into a 35-hour orbit that, if drawn, would appear oval shaped. Mars Reconnaissance Orbiter will dip into Mars' atmosphere during its orbital passes and the craft's large solar panels and high-gain antenna will create resistance, slowing the vehicle and moving it into a more circular orbit. At aerobraking's end, the spacecraft's orbit will be approximately two hours.

Streams of data poured in overnight as excited engineers and scientists waited to see what the High Resolution Imaging Science Experiment (HiRISE) camera was seeing from orbit around Mars. The results were worth waiting up for! Share in the excitement of the Mars Reconnaissance Orbiter's first images from orbit.
The Mars Reconnaissance Orbiter was farther from Mars when the camera took these test images than it will be when the mission's main science phase begins next fall, so the resolution of features in the images will not match what is anticipated later. However, this week's testing is the only planned use of the camera until the science phase begins.

Mars Reconnaissance Orbiter Successfully Enters Orbit Around Mars! |
|
Cheers of joy filled the mission control area at NASA's Jet Propulsion Laboratory today as its latest mission to Mars met a critical mission milestone: Mars orbit insertion. At 2:16 p.m. (PST), ground controllers were informed by the Deep Space Network that they had locked up on Mars Reconnaissance Orbiter's signal as the spacecraft reappeared above Mars. This communication was a tremendous relief to the mission team as they had to wait nearly half an hour for their spacecraft to emerge from behind the red planet and back into range so that radio signals could again be transmitted. A few minutes later, it was confirmed that the orbiter was captured into the intended initial orbit.
