Mars Pathfinder is an American robotic spacecraft that landed a base station with a roving probe on Mars in 1997. It consisted of a lander, renamed the Carl Sagan Memorial Station, and a lightweight, 10.6 kg (23 lb) wheeled robotic Mars rover named Sojourner, the first rover to operate outside the Earth–Moon system.
The Discovery Program is a series of Solar System exploration missions funded by the U.S. National Aeronautics and Space Administration (NASA) through its Planetary Missions Program Office. The cost of each mission is capped at a lower level than missions from NASA's New Frontiers or Flagship Programs. As a result, Discovery missions tend to be more focused on a specific scientific goal rather than serving a general purpose.
Steven Weldon Squyres is an American geologist and planetary scientist. He was the James A. Weeks Professor of Physical Sciences at Cornell University in Ithaca, New York. His research area is in planetary sciences, with a focus on large solid bodies in the Solar System such as the terrestrial planets and the moons of the Jovian planets. Squyres was the principal investigator of the Mars Exploration Rover Mission (MER).
An alpha particle X-ray spectrometer (APXS) is a spectrometer that analyses the chemical element composition of a sample from scattered alpha particles and fluorescent X-rays after a sample is irradiated with alpha particles and X-rays from radioactive sources. This method of analysing the elemental composition of a sample is most often used on space missions, which require low weight, small size, and minimal power consumption. Other methods are faster, and do not require the use of radioactive materials, but require larger equipment with greater power requirements. A variation is the alpha proton X-ray spectrometer, such as on the Pathfinder mission, which also detects protons.
Wesley T. Huntress, Jr. is an American space scientist. An astrochemist and space scientist, Huntress worked for about twenty years at NASA's Jet Propulsion Laboratory. During the 1980s, he was also a video game designer, producing games for Apple computers. In 1988, Huntress moved to NASA headquarters, where he would serve in several positions, including Director of NASA's Solar System Exploration Division and Associate Administrator for Space Science.

Harry "Hap" Y. McSween Jr. is Chancellor's Professor Emeritus of Planetary Geoscience at the University of Tennessee at Knoxville. He has published papers and popular books about meteorites and planetary exploration, and textbooks on geochemistry and cosmochemistry.
Maria T. Zuber is an American geophysicist who is the vice president for research at the Massachusetts Institute of Technology, where she also holds the position of the E. A. Griswold Professor of Geophysics in the Department of Earth, Atmospheric and Planetary Sciences. Zuber has been involved in more than half a dozen NASA planetary missions aimed at mapping the Moon, Mars, Mercury, and several asteroids. She was the principal investigator for the Gravity Recovery and Interior Laboratory (GRAIL) Mission, which was managed by NASA's Jet Propulsion Laboratory.
James F. Bell III is a professor of Astronomy at Arizona State University, specializing in the study of planetary geology, geochemistry and mineralogy using data obtained from telescopes and from various spacecraft missions. Bell's active research has involved the NASA Mars Pathfinder, Near Earth Asteroid Rendezvous (NEAR), Comet Nucleus Tour (CONTOUR), 2001 Mars Odyssey, Mars Reconnaissance Orbiter, Lunar Reconnaissance Orbiter, and the Mars Science Laboratory missions. His book Postcards from Mars includes many images taken by the Mars rovers. Bell is currently an editor of the space science journal Icarus and president of The Planetary Society. He has served as the lead scientist in charge of the Panoramic camera (Pancam) color imaging system on Mars rovers Spirit and Opportunity.
Heimdal is a relatively recent impact crater on the planet Mars. It is a simple crater which lies in Vastitas Borealis, the northern plain. It is named after the Norwegian town of Heimdal.
To date, interplanetary spacecraft have provided abundant evidence of water on Mars, dating back to the Mariner 9 mission, which arrived at Mars in 1971. This article provides a mission by mission breakdown of the discoveries they have made. For a more comprehensive description of evidence for water on Mars today, and the history of water on that planet, see Water on Mars.
Ronald Greeley was a Regents’ Professor in the School of Earth and Space Exploration (SESE) at Arizona State University (ASU), the Director of the NASA-ASU Regional Planetary Image Facility (RPIF), and Principal Investigator of the Planetary Aeolian Laboratory at NASA-Ames Research Center. He was involved with lunar and planetary studies since 1967 and most recently focused his research on understanding planetary surface processes and geologic histories.
Sojourner is a robotic Mars rover that landed in the Ares Vallis channel in the Chryse Planitia region of the Oxia Palus quadrangle on July 4, 1997. Sojourner was operational on Mars for 92 sols. It was the first wheeled vehicle to rove on a planet other than Earth and formed part of the Mars Pathfinder mission.

John T. Clarke is a professor of astronomy and director of the Center for Space Physics at Boston University. Clarke is best known for his Hubble Space Telescope observations of the aurora on Jupiter and Saturn, as well as over 260 papers in refereed journals, including every planet except Mercury and the interplanetary medium. Clarke's research is focussed on vacuum ultraviolet instrumentation and observations of planetary atmospheres. At present this includes primarily observations with the Hubble Space Telescope, overseeing the echelle channel on the MAVEN IUVS instrument orbiting Mars, and as Deputy-PI for the upcoming GLIDE mission to image the Earth's geocorona.
