The International Space Station’s Expedition 40 crew successfully captured Orbital Sciences’ Cygnus resupply vehicle with the station’s robotic arm at 6:36 a.m. EDT Wednesday.
Controlling the 57-foot Canadarm2 from a robotics workstation inside the station’s cupola, Commander Steve Swanson, with assistance from Flight Engineer Alexander Gerst, grappled Cygnus as it flew within about 32 feet of the complex. Flight Engineer Reid Wiseman joined his crewmates in the seven-windowed cupo [...]
Twenty years ago, human and robotic eyes observed the first recorded impact between cosmic bodies in the solar system, as fragments of comet Shoemaker-Levy 9 slammed into the atmosphere of Jupiter.
Between July 16 and July 22, 1994, space- and Earth-based assets managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, joined an armada of other NASA and international telescopes, straining to get a glimpse of the historic event:
NASA’s Galileo spacecraft, still a year-an [...]
All eyes are on ESA’s spaceplane to showcase reentry technologies after its unconventional launch on a Vega rocket this November.
Instead of heading north into a polar orbit – as on previous flights – Vega will head eastwards to release the spaceplane into a suborbital path reaching all the way to the Pacific Ocean.
“This is the first flight demonstration of features such as highly advanced thermal structures: thrusters and flaps that are part of the control system, and the 300 [...]
What happened to half of Saturn? Nothing other than Earth's Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun. This year the orbits of the Moon and Saturn have led to an unusually high number of alignments of the ringed giant behind Earth's largest satellite.
Technically termed an occultation, the above image captured one such photogenic juxtaposition from Buenos Aires, Argentina that occu [...]
This rock encountered by NASA's Curiosity Mars rover is an iron meteorite called "Lebanon," similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit and Opportunity. Lebanon is about 2 yards or 2 meters wide (left to right, from this angle). The smaller piece in the foreground is called "Lebanon B."
This view combines a series of high-resolution circular images taken by the Remote Micro-Imager (RMI) of Curiosity's Chemistry and Camera (ChemCa [...]
The six astronauts and cosmonauts of the International Space Station’s Expedition 40 crew supported a variety of science investigations Tuesday and squeezed in a final robotic practice session as they get set to capture a commercial cargo craft packed with more than a ton and a half of science and supplies.
Orbital Sciences’ Cygnus commercial cargo vehicle is closing in on the station with several rendezvous burns to fine-tune its path for a Wednesday morning rendezvous with the orbiting [...]
