passing this along from In Him Homeschoolers:
NASA today launched an update to the Spacewalk Game that enables players to virtually experience astronauts' adventures on the International Space Station from their computers.
This latest version gives players an unlimited supply of oxygen so that they can explore and learn more about how the station is assembled, take a spacewalk to bring station communications back online by powering an auxiliary antenna, or help tiny satellites or the Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) learn to fly in formation so that they can someday remotely help astronauts handle tasks. Players also can earn "badges" for completing missions and exploring the station. The updated game includes significant upgrades that load the game faster and make the graphics even more realistic.
More than 114,000 players have experienced the thrill of 3-D simulations of actual work astronauts performed during several NASA missions to provide power to the station and keep it operating at full capacity. The Station Spacewalk Game also incorporates graphics from real NASA missions and 3-D models. In addition to the Station Spacewalk Game, NASA provides interactive applications and other online educational tools as part of the agency's broader educational outreach effort to engage and inspire students in science, technology, engineering and mathematics.
