Curiosity (rover) composition of the artifact in minutes. Engineers created a smaller, portable version named the "X-Duetto". Fitting into a few briefcase-sized boxes, it can examine objects on site, while preserving their physical integrity. It is now being used by Getty scientists to analyze a large collection of museum antiques and the Roman ruins of Herculaneum, Italy. Prior to the landing, NASA and Microsoft released "Mars Rover Landing", a free downloadable game on Xbox Live that uses Kinect to capture body motions, which allows users to simulate the landing sequence. NASA gave the general public the opportunity from 2009 until 2011 to
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
