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 ...
Plot of velocity parameters and times on the horizontal axis, versus position on the vertical axis, for an accelerated twin roundtrip to a destination with Δx AB =10c 2 /α ~10 light years away if α~9.8 m/s 2. From the frame of reference of those on the ship the acceleration will not change as the journey goes on.
Mars 1962A was a Mars flyby mission, launched on October 24, 1962, and Mars 1962B an intended first Mars lander mission, launched in late December of the same year (1962). Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in orbit during the burn to put the spacecraft into trans-Mars ...
From initial hover, it tilted 5 degrees, allowing rotors to fly it 2 meters sideways. It stopped, hovered in place, and rotated counterclockwise, yawing from +90° to 0° to -90° to -180°, in 3 steps, to point its color camera in various directions to take photos. It flew back to the takeoff location and landed. [15] 3 April 25, 2021 at 11:31
A wide variety of sources [5] [6] [7] define LEO in terms of altitude.The altitude of an object in an elliptic orbit can vary significantly along the orbit. Even for circular orbits, the altitude above ground can vary by as much as 30 km (19 mi) (especially for polar orbits) due to the oblateness of Earth's spheroid figure and local topography.

Mach 1 on Mars can be about 240 m/s (790 ft/s) while it is about 332 m/s (1,090 ft/s) on Earth. [21] The Daedalus proposal in the canceled Mars Scout program designed a Mars glider that would fly over 400 km (250 mi) along the Coprates Chasma [22] Proposed Mars airplane concepts include: ARES (Aerial Regional-scale Environmental Survey) [23]
Even then, it would take 12 years for the first phase of MSR to at last fly. On Feb. 18, 2021, NASA’s Perseverance rover landed on Mars and began collecting soil, rock, and atmospheric samples ...
