Then-NASA Johnson Space Center deputy director Ellen Ochoa poses for a photo with Robonaut 2 (R2) during media day in the Space Vehicle Mock-up Facility on Aug. 4, 2010. R2 hitched a ride to the International Space Station with the STS-133. It was the first humanoid robot to travel to space and the first U.S.-built robot to visit the station. R2 will stay on...
Jupiter’s volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA’s Juno spacecraft. As with solar eclipses on the Earth, within the dark circle racing across Jupiter’s cloud tops one would witness a full solar eclipse as Io passes in front of the Sun. Such events occur frequently on Jupiter because it is...
In this image from June 2002, astronaut Franklin R. Chang-Diaz works with a grapple fixture during a spacewalk on the STS-111 mission to perform work on the International Space Station. The first spacewalk of the mission began with the installation of a power and data grapple fixture (PDGF) for the station’s robotic arm on the complex’s P6 truss....
This latest image of Jupiter, taken by NASA’s Hubble Space Telescope on Aug. 25, 2020, was captured when the planet was 406 million miles from Earth. Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the famous Great Red Spot region geari...
NASA’s Aqua satellite captured this true-color image of the United States on Sep. 15, 2020, showing the fires in the West, the smoke from those fires drifting over the country, several hurricanes converging from different angles, and Hurricane Sally making landfall. Red points in the west note areas that are significantly higher in temperature than the...
Dr. Frank Rubio was selected by NASA to join the 2017 Astronaut Candidate Class. He reported for duty in August 2017 and having completed the initial astronaut candidate training is now eligible for a mission assignment. The Florida native graduated from the U.S. Military Academy at West Point, New York, in 1998 and earned a Doctorate of Medicine from the Un...
During her first mission to space and to the International Space Station, Kate Rubins became the first person to sequence DNA in space. During her upcoming mission, Rubins will work on a cardiovascular experiment that builds on an investigation she completed during her first space mission and conduct research using the space station’s Cold Atom Lab. She’ll a...
Many colorful stars are packed close together in this image of the globular cluster NGC 1805, taken by the NASA/ESA Hubble Space Telescope. This tight grouping of thousands of stars is located near the edge of the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. The stars orbit closely to one another, like bees swarming around a hive. In the ...
Not every flight director is a legend, but some are. Take Eugene Kranz, for example. His heroic efforts saved the Apollo 13 mission from disaster. He also was an aerospace engineer, fighter pilot in the Korean War, and as Chief Flight Director, he directed missions from the Gemini and Apollo programs, including the first lunar landing mission, Apollo 11. He ...
This NOAA/NASA Suomi NPP satellite image from Sept. 7, 2020, shows the night band image of the Creek Fire at night as well as the smoke from the fire causing lights at night to diffuse or “bloom.” NASA’s satellite instruments are often the first to detect wildfires burning in remote regions, and the locations of new fires are sent directly to lan...
