Due to Mars's geological history, the possibility of past or present life on Mars remains of great scientific interest. Since the late 20th century, Mars has been explored by uncrewed spacecraft and rovers , with the first flyby by the Mariner 4 probe in 1965, the first orbit by the Mars 2 probe in 1971, and the first landing by the Viking 1 ...
Conceivably, if life exists (or existed) on Mars, evidence of life could be found, or is best preserved, in the subsurface, away from present-day harsh surface conditions. [57] Present-day life on Mars, or its biosignatures, could occur kilometers below the surface, or in subsurface geothermal hot spots, or it could occur a few meters below the ...
The history of Mars observation is about the recorded history of observation of the planet Mars. Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. Chinese records about the motions of Mars appeared before the founding of the Zhou dynasty (1045 BCE).
In its ancient past, Mars likely contained many of the necessarily ingredients for microbial life to flourish on its surface. Now, a new discovery by NASA’s Perseverance rover shows a trifecta ...
New images from NASA’s Mars Reconnaissance Orbiter may show where life first began on Mars. The site on southern Mars shows massive deposits in a basin that scientists say were formed a long ...
Study co-author Michael Manga, a UC Berkeley professor of Earth and planetary science, said jokingly that it could be a challenge for Elon Musk to solve. What does this mean for life on Mars?
The Phyllocian era correlates with the age of valley network formation on Mars, suggesting an early climate that was conducive to the presence of abundant surface water. It is thought that deposits from this era are the best candidates in which to search for evidence of past life on the planet.
The rover used its Mastcam instrument to capture the area on the 4,352 Martian day of the pioneering mission. Images of the area from NASA’s Mars Reconnaissance Orbiter had shown light-colored ...
