NASA's Parker Solar Probe is currently the fastest spacecraft ever launched. Planets all orbit the sun at different velocities, so they rarely form a straight line from the sun. (A rocket you made up or on the path which NASA has sent rovers?) However, they have elliptical (egg-shaped) paths. To most people (myself included) those are just numbers. They have computer systems on board that allow them to study their environment and avoid dangerous obstacles completely automatically, without human intervention. Related: What is the temperature on Mars? This page showcases our resources for those interested in learning more about Mars. Cassini's calculation was only off by 7% compared to today's more accurate measurements. You have to plan to make sure that by the time you reach the distance of Mar's orbit, Mars is where you need it to be! To most of us, dust is an annoyance. The Red Planet comes close enough for exceptional viewing only once or twice every 15 or 17 years. Atmosphere __________________________________ Giovanni made observations of Mars in 1672 from Paris, while his colleague, Jean Richer made the same observation from Cayenne, French Guiana. And although they get close and far apart, those points depend on where the planets are on their particular orbits. The farthest apart they can be is about 401 million km, or 401 billion meters. The reason Mars looks reddish is due to oxidization or rusting of iron in the rocks, regolith (Martian soil), and dust of Mars. Mars orbit, opposition and viewing opportunities. How long does it take to get to Mars? The fastest rocket leaving Earth travels at an average speed of approximately 3.6x109 miles per hour.
