PASSPORT TO KNOWLEDGE - To MARS with MER

OPPORTUNITY Small features with great significance!

January 28, 2004: Opportunity completes the first part of "stand-up" successfully, and has been sending back even more detailed images of the "bedrock" layers that will likely be the first target as it rolls away from the lander.

Space Shuttle Challenger Crew Memorialized on Mars
January 28, 2004

NASA announced plans to name the landing site of the Mars Opportunity rover in honor of the Space Shuttle Challenger's final crew. The area in the vast flatland called Meridiani Planum, where Opportunity landed this weekend, will be called the Challenger Memorial Station. The seven-member crew of Space Shuttle Challenger was lost when the orbiter suffered an in-flight breakup during launch Jan. 28, 1986, 18 years ago today.

NASA selected Meridiani Planum as a landing site because of extensive deposits of a mineral called crystalline hematite, which usually forms in the presence of liquid water. Scientists had hoped for a specific landing site where they could examine both the surface layer that's rich in hematite and an underlying geological feature of light-colored layered rock. The small crater in which Opportunity alighted appears to have exposures of both, with soil that could be the hematite unit and an exposed outcropping of the lighter rock layer.

Challenger's 10th flight was to have been a six-day mission dedicated to research and education, as well as the deployment of the Tracking and Data Relay Satellite-B communications satellite.

Challenger's commander was Francis R. Scobee and the mission pilot was Michael J. Smith. Mission specialists included Judith A. Resnik, Ellison S. Onizuka and Ronald E. McNair. The mission also carried two payload specialists, Gregory B. Jarvis and Sharon Christa McAuliffe, who was the agency's first teacher in space.

Opportunity successfully landed on Mars January 25 (Eastern and Universal Time; January 24 Pacific Time). It will spend the next three months exploring the region surrounding what is now known as Challenger Memorial Station to determine if Mars was ever watery and suitable to sustain life.

Opportunity's twin, Spirit, is trailblazing a similar path on the other side of the planet, in a Connecticut-sized feature called Gusev Crater.
