Summer of Discontent: 25 Years Since the Shuttle Hydrogen Leaks (Part 2)

In one of the most historic shuttle-era photographs ever taken, this image shows the STS-38/Atlantis stack (at right) returning to the Vehicle Assembly Building (VAB) for repairs on 9 August 1990. In doing so, it passed the STS-35/Columbia stack (at left), which was returning to the launch pad after several weeks of extensive repair […]

A quarter-century ago, in the summer of 1990, the shuttle program was in chaos. Less than two years since the resumption of flight operations in […]

Philae's First Science Results Highlight an Unexpected Cometary World

From ESA: "This well-lit image was acquired by Philae’s CIVA camera 4 at the final landing site Abydos, on the small lobe of Comet 67P/Churyumov–Gerasimenko, on 13 November 2014. The image shows one of the CONSERT antennas in the foreground, which seems to be in contact with the nucleus." CIVA's seven cameras captured images of Philae's position at its final landing site, Abydos. Image Credit: ESA/Rosetta/Philae/CIVA

From ESA: “Zooming in to a portion of the fractured cliff face imaged by CIVA camera 4 reveals brightness variations in the comet’s surface properties down to centimetre and millimetre scales. The dominant constituents are very dark conglomerates, likely made of organics. The brighter spots could represent mineral grains, perhaps even pointing to ice-rich […]

Three decades have now passed since one of the most dramatic missions—and one of the most dramatic months—in […]

Rosetta Team Troubleshoots Philae as Comet's Activity 'Heats Up'

From ESA: ““This single frame Rosetta navigation camera image of Comet 67P/Churyumov-Gerasimenko was taken on 14 July 2015 from a distance of 161 km from the comet centre. The image has a resolution of 13.7 m/pixel and measures 14 km across.” Image Credit: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0

'Going to Spain': 30 Years Since the Unlucky Success of Mission 51F (Part 1)

After one false start, Challenger roars into orbit on 29 July 1985, to begin the Spacelab-2 science mission. It would be one of the most dramatic near-misses in the 30-year shuttle program. Photo Credit: NASA

Thirty years ago, this week, one of the most significant Space Shuttle science missions ever undertaken hung—for the merest […]

Soyuz TMA-17M Crew Rockets to Orbit, Bound for Five Months Aboard Space Station
