Since the Viking landers that searched for current microbial life in 1976, NASA has pursued a "follow the water" strategy on Mars. However, liquid water is a necessary but not sufficient condition for life as we know it because habitability is a function of a multitude of environmental parameters. [323]
On March 2, 2004, NASA announced that "Opportunity has landed in an area of Mars where liquid water once drenched the surface". Associate administrator Ed Weiler told reporters that the area "would have been good habitable environment", although no traces of life have been found. Larger grains suggest the presence of fluid.
LOS ANGELES (Reuters) -NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater ...
Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, [2] which successfully landed Curiosity, a Mars rover, in Gale Crater on August 6, 2012. [ 3 ] [ 9 ] [ 10 ] [ 11 ] The overall objectives include investigating Mars' habitability , studying its climate and geology , and collecting data ...
On December 6, 2006 NASA released photos of two craters called Terra Sirenum and Centauri Montes which appear to show the presence of liquid water on Mars at some point between 1999 and 2001. [15] [16] Hundreds of gullies have been discovered that were formed from liquid water, possible in recent times.
The Mars Reconnaissance Orbiter (MRO) is a spacecraft designed to search for the existence of water on Mars and provide support for missions to Mars, as part of NASA's Mars Exploration Program. It was launched from Cape Canaveral on August 12, 2005, at 11:43 UTC and reached Mars on March 10, 2006, at 21:24 UTC.
Mars Express data shows that water molecules float higher than usual during the planet's warmer seasons, avoiding an Earth-like "cold trap" that keeps water close to the ground.
Wind Sensor; Humidity Sensor; The pressure sensor can detect pressures from 1 to 1150 Pa (0.000145038 PSI to 0.1667934 PSI). [11] For comparison, 1 atmosphere is 101,325 Pascals or 14.7 PSI. [12] The air temperature, wind speed and direction sensor for InSight Mars lander (planned for 2018 launch) is based on REMS, also contributed by Spain. [13]
