“一”'Intrepid' Crater on Mars (Color）

"Intrepid" crater on Mars carries the name of the lunar module of NASA's Apollo 12 mission,

which landed on Earth's moon Nov. 19, 1969.NASA's Mars Exploration Rover Opportunity

recorded this view of the crater during the 2,417th Martian day, or sol, of the rover's

work on Mars (Nov. 11, 2010).

This view is presented in approximately true color, combining exposures taken by

Opportunity's panoramic camera (Pancam) through three filters admitting wavelengths of 752

nanometers, 535 nanometers and 432 nanometers.Intrepid crater is about 20 meters (66 feet)

in diameter.That is about the same size as the crater where Opportunity spent its first two

months on Mars: Eagle crater.The rover's look-back image into Eagle crater after driving

out of it in 2004 is at http://photojournal.jpl.nasa.gov/catalog/PIA05755

The rover science team uses a convention of assigning the names of historic ships of

exploration as the informal names for craters seen by Opportunity.Apollo 12's lunar module

Intrepid carried astronauts Alan Bean and Pete Conrad to the surface of Earth's moon while

crewmate Dick Gordon orbited overhead in the mission's command and service module, Yankee

Clipper.A view of Bean next to Intrepid on the moon is online at

of Conrad inspecting robotic lander Surveyor 3, with Intrepid on the lunar horizon nearby,

is online at http://spaceflight.nasa.gov/gallery/images/apollo/apollo12/html/as12-48-

 “二”'Yankee Clipper' Crater on Mars

"Yankee Clipper" crater on Mars carries the name of the command and service module of NASA's 1969 Apollo 12 mission to the moon.NASA's Mars Exploration Rover Opportunity recorded this view of the crater during a pause in a 102-meter (365-foot) drive during the 2,410th Martian day, or sol, of the rover's work on Mars (Nov. 4, 2010).

This view is a mosaic of three frames taken by the left eye of Opportunity's navigation camera.Yankee Clipper crater is about 10 meters (33 feet) in diameter.

The rover science team uses a convention of assigning the names of historic ships of exploration as the informal names for craters seen by Opportunity.Apollo 12's Yankee Clipper orbited Earth's moon while the mission's lunar module carried two astronauts to the lunar surface on Nov. 19, 1969, and later brought all three of the mission's astronauts back to Earth, arriving Nov. 24, 1969.A dramatic view of Earth rising over a lunar horizon, taken from Apollo 12's Yankee Clipper, is online at http://spaceflight.nasa.gov/gallery/images/apollo/apollo12/html/as12-47-6891.html .
