Curiosity (rover) counted. Previous NASA Mars rovers became active only after the successful entry, descent and landing on the Martian surface. "Curiosity", on the other hand, was active when it touched down on the surface of Mars, employing the rover suspension system for the final set-down. "Curiosity" transformed from its stowed flight configuration to a landing configuration while the MSL spacecraft simultaneously lowered it beneath the spacecraft descent stage with a tether from the "sky crane" system to a soft landing—wheels down—on the surface of Mars. After the rover touched down it waited 2 seconds to confirm that it was on solid
Gliese 687 X-rays. Gliese 687 Gliese 687, or GJ 687 "(Gliese–Jahreiß 687)" is a red dwarf in the constellation Draco. This is one of the closest stars to the Sun and lies at an approximate distance of less than 15 light years. Even though it is close by, it has a magnitude of about 9, so it can only be seen through a moderately sized telescope. Gliese 687 has a high proper motion, advancing 1.304 arcseconds per year across the sky. It has a net relative velocity of about 39 km/s. It is known to have a Neptune-mass planet. Gliese 687 has
