On July 29, 1985, the Space Shuttle Challenger launched on the STS-51F mission. In a dramatic first, the shuttle successfully completed an abort to orbit. An early shutdown of one of the RS-25 engines meant that the Challenger wasn’t able to reach as high of an orbit as planned, but the mission was still Go since the shuttle was able to use the remaining two SSMEs to reach a stable orbit. This was the first and only time an abort to orbit was performed during the 135 shuttle flights.
This dramatic camera angle shows Challenger, as it rose from the Pad 39A. Challenger’s crew carried out experiments studying life sciences, plasma physics, solar physics, high-energy astrophysics, astronomy, and some cans of soda designed to operate in microgravity.
Programming note- check out this post for details on how you can get cool stuff for recommending The Space Shot to friends, coworkers, and random people on the street, you get the gist.
This weird payload, part of the “Cola Wars,” flew on STS-51F. The crew of the Challenger, pictured below, performed taste tests on Pepsi and Coca-Cola while in orbit. It seems that neither cola won accolades from the crew. The cans pictured below are on display at the Cosmosphere in Hutchinson, Kansas. The item description for these artifacts notes, “Both colas tasted like a bottle that had been opened and then forgotten about.”
In addition to the bad taste, carbonation and microgravity were a bad combination for astronauts. The carbonation caused the astronauts to experience wet burps, which must have been one heck of a “foamy mess during space travel.”
According to NASA, “In space, with the absence of gravity, the carbon dioxide bubbles in carbonated beverages go through an astronaut’s digestive system, rather than being belched out as on Earth, and may cause adverse side effects.”
Sharing The Space Shot now will get you entered for a chance to win some awesome Skylab 50th prizes, including a signed copy of “Homesteading Space: The Skylab Story” or space-themed jewelry, coffee, or stickers. There will be prize drawings from now until the Splashdown of Skylab 3 at the end of September. So share away!
Here’s one more picture of the crew of STS-51F. I wish it wasn’t blurry because the crew is rocking multiple sets of American Optical Original Pilot sunglasses. So freaking cool 😎
Having a variety of drinks and food in space is a critical part of a crew’s well-being. Thankfully, not all space-based drink experiments have been failures, the ISSpresso machine was used to great success onboard the International Space Station for 32 months.
Lavazza, Argotec, and the Italian Space Agency developed ISSpresso, and crews used the machine on 11 different ISS Expeditions. As a caffeine and espresso connoisseur, I fully endorse the use of coffee-based caffeine delivery systems in space.
ESA astronaut Samantha Cristoforetti dressed up as Captain Janeway from Star Trek: Voyager, enjoys a shot of espresso from the ISSpresso machine in one of the ingenious Zero-G cups that use the capillary effect to simulate drinking from a cup. This stunning picture was captured in the Cupola on the ISS during Expedition 43.
