2001 Mars Odyssey first few minutes on the Martian surface. "Odyssey" also acts as a relay for UHF radio signals from the (MSL) rover "Curiosity". Because "Odyssey" is in a Sun-synchronous orbit, it consistently passes over "Curiosity"s location at the same two times every day, allowing for convenient scheduling of contact with Earth. 2001 Mars Odyssey 2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars. The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million. Its mission is to use spectrometers and a thermal imager to detect evidence
Gliese 687 40% of the Sun's mass and nearly 50% of the Sun's radius. Compared to the Sun, it has a slightly higher proportion of elements with higher atomic numbers than helium. It appears to have a rotation of 60 days and to be somewhat chromospherically active. It displays no excess of infrared radiation that would indicate orbiting dust. It is known to have a planet, Gliese 687 b, with a mass of 18.394 Earth masses (which makes it comparable to Neptune), an orbital period of 38.14 days, and a low orbital eccentricity. Gliese 687 is a solitary red dwarf that emits
