On October 11, 1968, NASA launched the first Apollo crew into space. This mission, Apollo 7, opened the spaceways for the moon landing the following July. Apollo 7 had the following objectives: Demonstrate Command and Service Module (CSM) with crew performance; demonstrate mission support facilities' performance during a crewed mission and demonstrate Apollo rendezvous capability; demonstrate live TV broadcasts from space.
The Apollo 7 crew was commanded by Walter Schirra, with Command Module Pilot Donn Eisele, and Lunar Module Pilot Walter Cunningham. The mission consisted of an 11-day Earth-orbital test flight to test the Apollo command and service module. It was also the first time a crew flew on the Saturn IB rocket.
Although Apollo 7 was a complete technical success, it was born out of a tragedy. After the fatal fire that took the lives of the Apollo 1 crew—Gus Grissom, Roger Chaffee, and Ed White—the Apollo 7 crew took over the mission.
Apollo 1 was supposed to be the first crewed Apollo mission. During a launch rehearsal test at Cape Kennedy, an electrical fire broke out in the cabin. Because the cabin atmosphere was pure oxygen, the fire spread incredibly quickly. The fire also created intense pressure inside the cabin, and because the hatch could only swing inward, the crew was stuck inside.
All further crewed missions had to wait until NASA could determine the sources of the mishap—technical and organizational—and ensure that nothing like it would happen again. In the 21 months between Apollo 1 and Apollo 7, the Apollo spacecraft and spacesuits were redesigned to more safely fly crews to space.
RIP Starship SN4 😭https://t.co/klPMtZHxjW pic.twitter.com/hrrElBXmSC — Chris B – NSF (@NASASpaceflight) May 29, 2020 SpaceX’s Starship SN4 prototype launch vehicle just exploded in a huge fireball during a static fire test in Boca Chica, Texas. While the Starship spacecraft is still early in development, the explosion doesn’t feel great leading up to the SpaceX-NASA historic […]
Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)
On Tuesday evening, the night before NASA astronaut Bob Behnken was set to launch into orbit about a SpaceX Falcon 9 rocket and Crew Dragon capsule, he launched his own rocket from Florida’s Atlantic Coast.
Software apps are a dime a dozen. Well, if you’re going by their actual monetary cost, maybe not really. But considering how useless some poorly conceived, poorly executed apps are at doing the job you actually downloaded them to accomplish, it isn’t a stretch to think that many apps aren’t even worth a free download. […]
With everything happening in the last few months, we all but guarantee no one has been thinking about their taxes. That’s understandable — because, beyond all of our current concerns, nobody enjoys the whole tax filing process during even the best of times. Unfortunately, Benjamin Franklin was right — taxes truly are as inescapable as […]
Most parents know that giving their kids educational toys and other projects will expand their minds. But what many might not realize is that physical play is actually building their mental abilities as well. Studies are still in beginning stages, but some early research supports the theory that kids who get the chance to get […]
