Dave Griggs, pictured during the Space Shuttle program’s first contingency spacewalk in April 1985, lost his life 30 years ago this month. Photo Credit: NASA Thirty years ago, America’s Space Shuttle program had risen from the depths of despair—following the calamitous loss of Challenger—to a triumphant return-to-flight and the three surviving orbiters, Columbia, Discovery […] 
An ominous cloud of smoke billows away from Pad 39A in the seconds after a problematic Main Engine Start on 26 June 1984. Photo Credit: NASA More than 30 summers ago, America’s shuttle program should have entered its prime. Touted for over a decade as capable of flying regularly and routinely, the early […] 
Spectacular view of Columbia’s payload bay and aft compartment, during STS-75. Photo Credit: NASA, via Joachim Becker/SpaceFacts.de Two decades ago, Space Shuttle Columbia rocketed into orbit carrying one of the most unusual experiments on record: the reflight of the Tethered Satellite System (TSS-1R). It was intended to demonstrate the “electrodynamics” of a conducting […] 
The STS-75 crew pose for their official portrait. Seated are Pilot Scott “Doc” Horowitz, Commander Andy Allen, and Payload Commander Franklin Chang-Diaz, with Maurizo Cheli, Umberto Guidoni, Jeff Hoffman, and Claude Nicollier standing.

Photo Credit: NASA, via Joachim Becker/SpaceFacts.de Had history smiled with more favor, ASTRO-1 might have taken place almost three decades ago, but the space shuttle’s first mission totally dedicated to astrophysics was repeatedly delayed in the aftermath […] But for the tragic loss of Challenger, the ASTRO-1 mission might have flown just five weeks later, in March 1986. As circumstances transpired, it would be more than four years before the mission rose into orbit. Photo Credit: NASA, via Joachim Becker/SpaceFacts.de A quarter-century ago, this week, four powerful ultraviolet and X-ray “eyes” […] Astronaut Story Musgrave is positioned to replace components at the end of Endeavour’s Remote Manipulator System (RMS) mechanical arm on STS-61 in December 1993. Photo Credit: NASA More than two decades have passed since one of the most spectacular EVA missions in U.S. history: the long-awaited first servicing of the Hubble Space Telescope […] Spacewalkers Jeff Hoffman and Dave Griggs work to outfit a makeshift fly swatter onto the Remote Manipulator System (RMS) mechanical arm, in a fruitless attempt to activate Syncom 4-3’s deploy switch. Photo Credit: NASA Thirty years ago, next week, the crew of Mission 51D watched open-mouthed as a powerful communications satellite which they […] Spacewalkers Jeff Hoffman and Dave Griggs work to outfit a makeshift fly swatter onto the Remote Manipulator System (RMS) mechanical arm, in a fruitless attempt to activate Syncom 4-3’s deploy switch.

Photo Credit: NASA Ironically, the spacecraft from which the most Extravehicular Activities (EVAs) were performed—the space shuttle—was not originally intended to carry the capability for spacewalking […] |
