Which of these is NOT now on the surface of Mars?
A
Mars Global Surveyor
B
Viking 1
C
Pathfinder
D
Sojourner
E
Spirit
Explanation: 

Detailed explanation-1: -The Mars Global Surveyor orbiter, which operated on Mars for more than nine years, was designed to study the composition of Mars, map its topography and monitor weather patterns. The orbiter made a number of discoveries about the Red Planet, including evidence of liquid water at or near the Martian surface.

Detailed explanation-2: -Mars Global Surveyor sent more than 240, 000 images to Earth. It scouted landing sites for the Spirit, Opportunity and Curiosity rovers as well as the Phoenix lander. It also served as a communications relay for rovers on the surface. The mission ended in November 2006.

Detailed explanation-3: -Mars Exploration Program Attempts to recontact the spacecraft and resolve the problem failed, and NASA officially ended the mission in January 2007. MGS remains in a stable near-polar circular orbit at about 450 km altitude and as of 1996, was expected to crash onto the surface of the planet in 2050.

Detailed explanation-4: -Mars Pathfinder was a U.S. spacecraft that landed a base station with a roving probe on Mars on July 4, 1997. It consisted of a lander and a small 10.6-kilogram (23 lb) wheeled robotic rover named Sojourner, which was the first rover to operate on the surface of Mars.

Detailed explanation-5: -The Mars Global Surveyor (MGS) began its primary mission on March 9, 1999, and continued through a series of extended missions until November 2, 2006, when communication with the spacecraft was lost. MGS carried these experiments: MOLA-Mars Orbiter Laser Altimeter.

Detailed explanation-6: -High-resolution images returned from the spacecraft indicated that liquid water may have existed on or near the planet’s surface in geologically recent times and may still exist in protected areas. Mars Global Surveyor was launched on November 7, 1996.
