Images of Mars taken from orbit show thousands of mounds in a region sculpted by water billions of years ago. A robotic mission may investigate the area one day.
Curiosity rover on Mars (5 August 2015) The Mars Science Laboratory and its rover, Curiosity, were launched from Earth on 26 November 2011. As of February 7, 2025, Curiosity has been on the planet Mars for 4446 sols (4568 total days; 12 years, 185 days) since landing on 6 August 2012. (See Current status.)
Pre-Noachian: the interval from the accretion and differentiation of the planet about 4.5 billion years ago to the formation of the Hellas impact basin, between 4.1 and 3.8 Gya. [13] Most of the geologic record of this interval has been erased by subsequent erosion and high impact rates.
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 ...
The bottom of the Jezero Crater – believed to have formed 3.9 billion years ago from a massive impact – is considered to be among the most promising areas on Mars to search for evidence of ...
The magnetic field of Mars is the magnetic field generated from Mars's interior. Today, Mars does not have a global magnetic field. However, Mars did power an early dynamo that produced a strong magnetic field 4 billion years ago, comparable to Earth's present surface field. After the early dynamo ceased, a weak late dynamo was reactivated (or ...
It is 154 km (96 mi) in diameter [1] and estimated to be about 3.5–3.8 billion years old. [3] The crater was named after Walter Frederick Gale, an amateur astronomer from Sydney, Australia, who observed Mars in the late 19th century. [4] Mount Sharp is a mountain in the center of Gale and rises 5.5 km (18,000 ft) high.
