Originally released Aug. 1, 2007, this Mars Reconnaissance Orbiter image shows an ridge in Mars' Terra Meridian that is most likely a former stream bed, now exposed in inverted relief.

The stream that formed this ridge must have been ancient as the ridge is buried by brighter rocks, which are themselves very old, having been thickly deposited and then heavily eroded. The Mars Exploration Rover

Opportunity landed in the same region of Mars, and the rocks it has examined are likely part of a sequence similar to that exposed here. The rocks exposed at the Opportunity landing site are mostly wind-deposited

sandstone, but show evidence of past water, reaching the surface at times.
Opportunity has access to only a few meters of a stack of sediments that is hundreds of meters thick.

Urgent News

NASA managers have targeted space shuttle Discovery's launch for no earlier than Feb. 3 at 1:34 a.m. EST. Shuttle managers determined more tests and analysis are needed before proceeding with the launch of the STS-133 mission to the International Space Station.

The Program Requirements Control Board met Thursday and reviewed engineering evaluations associated with cracks on two 21-foot-long,

U-shaped aluminum brackets, called stringers, on the shuttle's external tank. NASA repaired the cracks and reapplied foam to the

exterior of the stringers. Managers decided the analysis and tests required to launch Discovery safely are not complete. They are planning to conduct an instrumented test on the external fuel tank and structural evaluations on stringer test articles to determine whether the analysis is correct. Details and timelines for the tanking test are in work, but plans call for temperature and strain gauge measurements in the intertank region near the top of the tank during the test.

NASA will review and analyze the data from the tests before setting a launch date. Because of Discovery's delayed launch, the earliest

opportunity for the liftoff of the final scheduled shuttle mission, STS-134 on Endeavour, is April 1.
