With the success of Project Rover, NASA set its sights on the human missions to Mars that would follow the Apollo landers on the Moon. Because of the distance and flight time, they decided nuclear rockets would be the key to making the missions more capable. Nuclear rockets aren’t without...
The rotation period, or length of a sidereal day (see day; sidereal time)—23 hours, 56 minutes, and 4 seconds—is similar to that of Mars. Jupiter and most asteroids have days less than half as long, while Mercury and Venus have days more nearly comparable to their orbital periods. ...
Notes:LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. Cosmic Rays in the Atmosphere SPACE WEATHER BALLOON DATA:Almost once a week, Spaceweather.com and the students ofEarth to Sky Calculusfly space weather balloons to...
The distance between Mars and the center of the Earth, in astronomical units (A.U.), was calculated. RME(min) was found to be between 0.4763 and 0.5108, and RM-E(max) was found to be between 2.548 and 2.6259. Furthermore, the findings revealed that the Mars orbital...

Distance Between Earth and Mars: Earth and Mars Opposition: Dec. 24, 2007 - 88.2 million km (54.8 million miles) Jan. 29, 2010 - 99.3 million km (61.7 million miles) Mar. 03, 2012 - 100.7 million km (62.6 million miles) Apr. 08, 2014 - 92.4 million km (57.4 million miles) ...
Earth at 10:18 am ET on October 6. Mars will be 38,586,816 miles away from Earth --- yes, that's close for Mars -- and it won't be this close again until 2035. Mars in 2003 made its closest approach to Earth in 60,000 years, coming within a distance of 34.65 million miles...

The new experiment increases the distance the transmission had to travel — 16 light minutes, or about 288 million kilometres, from where the European Space Agency’s ExoMars orbiter was circling Mars. And rather than sending the pre-formatted Arecibo message, the orbited beamed a message that ...
Well, let’s have a look atMars. After all, this is a very Earth-like planet in our solar system and a likely candidate, at some point, for extraterrestrial colonization. The red planet orbits the Sun at a greater distance than Earth, so aMars year takes much longer: 686.973 Earth days...
