In the International Space Station’s Destiny laboratory, Robonaut 2 is pictured on Jan. 2, during a round of testing for the first humanoid robot in space. Ground teams put Robonaut through its paces as they remotely commanded it to operate valves on a task board.Robonaut is a testbed for exploring new robotic capabilities in space, [...]

A solar eruption gracefully rose up from the sun on Dec. 31, 2012, twisting and turning. Magnetic forces drove the flow of plasma, but without sufficient force to overcome the sun’s gravity much of the plasma fell back into the sun. The length of the eruption extends about 160,000 miles out from the Sun. With [...]

Snow-covered deserts are rare, but that’s exactly what the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite observed as it passed over the Taklimakan Desert in western China on Jan. 2, 2013. Snow has covered much of the desert since a storm blew through the area on Dec. 26. The day after the storm, [...]

After more than a month of eruption, lava continues to flow from Tolbachik, one of many active volcanoes on Russia’s Kamchatka Peninsula. The current eruption at Tolbachik began on Nov. 27, 2012. Lava flowed up to 20 kilometers (12 miles) from a line of fissures on the volcano’s southern flank. Since then, some of the [...]

The Hubble Space Telescope captured a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097. In this image, the larger-scale structure of the galaxy is barely visible: its comparatively dim spiral arms, which surround its heart in a loose embrace, reach out beyond the edges of [...]

The spiral galaxy NGC 3627 is located about 30 million light years from Earth. This composite image includes X-ray data from NASA’s Chandra X-ray Observatory (blue), infrared data from the Spitzer Space Telescope (red), and optical data from the Hubble Space Telescope and the Very Large Telescope (yellow). The inset shows the central region, which [...]

On the 84th and 85th Martian days of the NASA Mars rover Curiosity’s mission on Mars (Oct. 31 and Nov. 1, 2012), NASA’s Curiosity rover used the Mars Hand Lens Imager (MAHLI) to capture dozens of high-resolution images to be combined into self-portrait images of the rover. The mosaic shows the rover at “Rocknest,” the [...]

While the Dawn spacecraft is visiting the asteroids Vesta and Ceres, NASA Glenn has been developing the next generation of ion thrusters for future missions. NASA’s Evolutionary Xenon Thruster (NEXT) Project has developed a 7-kilowatt ion thruster that can provide the capabilities needed in the future. An ion thruster produces small levels of thrust relative [...]

Three 300-pound main parachutes gently lower a mockup Orion capsule to the ground during a test at the U.S. Army Yuma Proving Ground in Arizona on Dec. 20. The test verified that the parachute design for the spacecraft – which will take humans farther than they’ve ever been before and return them to Earth at [...]
