NASAs GRAIL mission is comprised of a pair of mirror-identical spacecraft to the Earths Moon to perform precision gravity measurements. The gravity field will allow scientists to determine the structure of the Moons interior from the surface to the deep interior, advance our understanding of the thermal evolution of the Moon and our understanding of how other rocky planets in the solar system are formed. Later versions of the app will include images captured by MoonKAM

NASA HIAD

A giant cone of inner tubes stacked together may someday help cargo, or even people, land on another planet or return to Earth. To successfully guide an inflatable spacecraft through the super heat of atmospheric re-entry requires the right stuff. To successfully reach the target, players must:Undock from the ISS and use thruster control to steer the spacecraft towards the desired de-orbit point Inflate the HIAD aeroshell to reduce velocity and protect the payload from the heat of atmospheric re-entry Steer the inflated HIAD to the ground target prior to parachute deployment, taking into account the prevailing winds Customize the HIAD vehicle to achieve different performance characteristics to improve resultsFEATURESMultiple spacecraft configurations and optionsSpeed and trajectory controlsIn-game introductionFour levels of engineering masteryLocked levelsScoring for each levelHelp sectionLinks to related website
