Mars spins a little more quickly each year, according to data collected by NASA’s now-retired InSight lander.
The Red Planet's spin is speeding up a hair fast enough to shorten the length of a Martian day by a fraction of a millisecond per year. NASA's Mars Insight lander died a few months ago, no longer ...
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. [138] Solar-electric propulsion could allow a one launch sample return instead of three. [139]

Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...
[6] [10] Two castles would be used, an outbound one on an Aldrin cycler with a fast transfer to Mars and long trip back, and an inbound one with fast trip to Earth and long return to Mars, [3] which Aldrin called up and down escalators. [6] The astronauts would meet up with the cycler in Earth orbit and later Mars orbit in specialised craft ...
Rotation and Interior Structure Experiment (RISE) is a radio science experiment onboard InSight Mars lander that will use the spacecraft communication system to provide precise measurements of Mars' rotation and wobble. RISE precisely tracks the location of the lander to measure how much Mars's axis wobbles as it orbits the Sun.
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]
