The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost 60,000 years (57,617 BC). The record minimum distance between Earth and Mars in 2729 will stand at 55.65 million km.
The samples would be returned to Earth by July 2031. [137] NASA-ESA Mars Sample Return is a three-launch architecture concept for a sample return mission, which uses a rover to cache small samples, a Mars ascent stage to send it into orbit, and an orbiter to rendezvous with it above Mars and take it to Earth.

This system is also much more precise: while the Mars Exploration Rovers could have landed anywhere within their respective 93-mile by 12-mile (150 by 20 kilometer) landing ellipses, Mars Science Laboratory landed within a 12-mile (20-kilometer) ellipse. [7] Mars 2020 has even more precise system, and landing ellipse of 7.7 by 6.6 km. [8]
Mars spins a little more quickly each year, according to data collected by NASA’s now-retired InSight lander. ... A Martian day lasts about 40 minutes longer than a day on Earth.
NASA released a stunning image on Friday showing our home planet as well as the moon from Mars.
An areosynchronous orbit that is equatorial (in the same plane as the equator of Mars), circular, and prograde (rotating about Mars's axis in the same direction as the planet's surface) is known as an areostationary orbit (AEO). To an observer on the surface of Mars, the position of a satellite in AEO would appear to be fixed in a constant ...
For example, NASA's Curiosity rover (landed on Mars in Aug 2012) has a budget exceeding $2.5 billion. [5] NASA also has goals of collaborating with the European Space Agency (ESA) in order to conduct a mission involving returning a sample of Mars soil to Earth, which would likely cost at least $5 billion and take ten years to complete.

Failed to reach the Moon as intended, but reached a record–setting distance of 113,800 kilometres (70,700 mi) from Earth. USA 11 October 1958 Earth: Luna 1: First spacecraft to achieve Earth's escape velocity. USSR 4 January 1959 Moon: Luna 1: First flyby. Distance of 5,995 kilometres (3,725 mi).
