However, a Mars year is almost twice as long as an Earth ... (20.5 km) west of the reference longitude, so the lander mission clock is 1 minute and 23 seconds ahead ...
The basic time periods from which the calendar is constructed are the Martian solar day (sometimes called a sol) and the Martian vernal equinox year.The sol is 39 minutes 35.244 seconds longer than the Terrestrial solar day, and the Martian vernal equinox year is 668.5907 sols in length (which corresponds to 686.9711 days on Earth).
It is approximately 24 hours, 39 minutes, 35 seconds long. A Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days [ 1 ] or 1.88 Earth years. The sol was adopted in 1976 during the Viking Lander missions and is a measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover .
the Sol system: 668 sols per Mars Year. This system consists of uniform time units. However, Mars Year sols may be confused with rover mission times that are also expressed in sols. Unlike in the day vs. sol distinction, "Mars Year" has no unique Latin term. Start and End dates of Mars Years were determined for 1607–2141 by Piqueux et al. [2 ...
Ingenuity, nicknamed Ginny, is an autonomous NASA helicopter that operated on Mars from 2021 to 2024 as part of the Mars 2020 mission. Ingenuity made its first flight on 19 April 2021, demonstrating that flight is possible in the extremely thin atmosphere of Mars, and becoming the first aircraft to conduct a powered and controlled extra-terrestrial flight.

At 6 km (3.7 mi) altitude, traveling at about 250 meters per second (820 feet per second), the 16 m diameter lander parachutes deployed. Seven seconds later the aeroshell was jettisoned, and eight seconds after that the three lander legs were extended. In 45 seconds, the parachute had slowed the lander to 60 meters per second (200 feet per ...
The company is one of NASA's largest contractors and is one of several currently working on projects related to Mars. So far, only unmanned rovers and orbiters have made it to the Red Planet. When ...
