Trial By Fire - STS 1/Columbia test firing and launch.
STS-1 was essentially a proof-of-concept mission. The idea was to exercise the main components of the incredibly complex shuttle and see if they worked the way engineers had predicted. As many as eight astronauts would eventually crew the shuttle, but only two seats were occupied on that first mission. Young shared the flight deck with pilot Robert Crippen. This marked the first time that humans were aboard the maiden flight of a US rocket.
Columbia successfully completed a twenty second Flight Readiness Firing (FRF) of her three Space Shuttle Main Engines (SSMEs) on February 20, 1981.
With a successful FRF, Columbia’s maiden flight was then set for March. However, a series of issues, including the asphyxiation deaths of two Rockwell technicians on March 19 following a countdown rehearsal, pushed the launch to April 5, then April 7, and then April 10 to verify TPS foam fixes to Columbia’s External Tank. The April 10 launch was scrubbed because Columbia's four primary general purpose computers (GPCs) failed to provide correct timing to the backup flight system (BFS) when the GPCs were scheduled to transition from vehicle checkout to flight configuration mode.
At 07:00:03 EST April 12 1981, the Space Shuttle Columbia left LC-39A, on only its second launch attempt after 105 days on the launch pad, to inaugurate the Space
Shuttle Program. Liftoff of STS-1 occurred exactly 20 years to the day of the first manned space flight by Yuri Gagarin. #spaceflight#rocketsspace#spaceexplorers#astronaut#spaceman#astronautics#spacetravel#spacemissions#spacemen#stargazing#spaceshuttle#spacesuits#manonthemoon#projectapollo#spacehistory#spaceconquest#spacerace#apollo50#apolloprogram#spacestation#saturnv#moonlanding#Rocketry#nasa#spacecraft#rocket#nerd#awesome#spacex#cosmonauts
It was an absolute honour to be joined by former @nasa astronaut and professor of engineering from @tamu University Greg Chamitoff. Greg was a crew member of 3 space shuttle missions (STS-124, STS-126 and STS-134) flying on board Discovery and Endeavour and spent a total of 6 months aboard the ISS. We had the opportunity to talk about his experience in space, show him around our lab and discuss our plans leading up to Spaceport America Cup.
Rendering of the proposed Aerojet General M-1. Unlike Rocketdyne's F-1 which was used RP-1 (rocket-grade kerosene) and LOX, the M-1 used H2 and LOX. This engine was in development during the early '60s for uprated Saturn and/or Nova launch vehicles, but was eventually cancelled before full development. Even though the M-1 was physically larger than the F-1 and had a higher specific impulse, it did not produce as much thrust and would likely have required larger tanks and structure to accommodate a set of these massive engines.
Render dari Aerojet General M-1 yang diusulkan. Tidak seperti Rocketdyne's F-1 yang menggunakan RP-1 (roket berbahan bakar minyak tanah) dan LOX, M-1 menggunakan H2 dan LOX. Mesin ini dikembangkan pada awal 60-an untuk Roket Saturn / Nova, tetapi akhirnya dibatalkan sebelum pengembangan penuh. Meskipun M-1 secara fisik lebih besar dari F-1 dan memiliki dorongan spesifik yang lebih tinggi, M-1 tidak menghasilkan daya dorong lebih banyak dan kemungkinan akan membutuhkan tangki dan struktur yang lebih besar untuk mengakomodasi satu set mesin besar ini.

🚀💦The fifth grade launched their water rockets on Frank Field after school today! It’s an annual tradition around here that we love, and it’s Ms. Hoffman’s science class’s culminating project that combines the engineering skills they’ve practiced all year with a fun design challenge. Which team came out on top this year? Team Pink Pineapple? Team Flaming Hot Cheeto Puffs? The Flying Chickens? Ask a fifth grader when you see them and we’re sure they’ll tell you... #westridgeschool
