The science astronauts - Owen, Ed and Joe would fly on #Skylab!

#Skylab's Jack Lousma demonstrates a cozy nook onboard the Space Shuttle - flying from one era to another!

Beautiful, colorful diagrams illustrating #Skylab's Earth surface photography operations.

Jack Lousma! #Skylab

Gerry, Bill, Ed - the crew of #Skylab 4!

A look at the business end of Skylab.

The Neutral Buoyancy Simulator was the big water tank used to train #Skylab astronauts in spacewalking around the station.

Dr Joe and bubbles of water in microgravity! #Skylab

A spectacular solar flare photographed from Skylab.

Skylab's Joe Kerwin poses with Astronaut Candidate Anna Fisher after pool training. Apparently Fisher got to wear Pete Conrad's training suit, because it was the smallest available! Shuttle suits were still underway. What a fascinating view into generations meeting, and learning from one another.

While Skylab was being assembled, these were the dreams. #NASA images.

This is the end of the real-time coverage of Skylab 3. We will return on November 16 for Skylab 4! Stay tuned meanwhile with updates on other exciting Skylab history stories. #Skylab50 #SkylabOTD

Welcome back, Skylab 3! Al, Owen and Jack splashed down #OTD in 1973!

It's splashdown day! And the crew of Skylab 3 started it with style. #Skylab50 #SkylabOTD

It was the last full day of the mission, and the jokes are reflective of this fact. #Skylab50 #SkylabOTD

Campaign exhaustion was perhaps starting to set in as the crew debated the topic of returning some Skylab food items to Earth for analysis. Bruce McCandless II in Mission Control supplied remarks. #Skylab50 #SkylabOTD

Football scores! #Skylab50 #SkylabOTD

We feel that the crew of Skylab 3 is only getting funnier towards the end of their mission. #Skylab50 #SkylabOTD

Now we want to know about the coin trick too! #Skylab50 #SkylabOTD

The Skylab crew had their sleep patterns adjusted, which made for more fun and games with the CapCom. #Skylab50 #SkylabOTD

Today, the joking just went on and on. So enjoy Jack's Japanese skills, and endless ribbing of the flight control team by the crew. All in good fun. #Skylab50 #SkylabOTD

Spacecraft can be noisy, and people are especially noisy. Today, CapCom Bob Crippen recalled how his SMEAT colleague Bill Thornton's endless cycling kept interrupting the others. According to Al Bean, history was repeating itself on Skylab. #Skylab50 #SkylabOTD

Sad news from Skylab today: Anita the spider had apparently succumbed to the stresses of spaceflight, after an exciting mission. #Skylab50 #SkylabOTD

Vale Robert Redford.

On the news today: forest fires, Skylab's success, and the upcoming Battle of the Sexes 1973, featuring tennis stars Bobby Riggs and Billie Jean King. Wonder who won... #Skylab50 #SkylabOTD

The Skylab astronauts had a limited number of shoes at their disposal, and the wear and tear required some duct tape repairs. #Skylab50 #SkylabOTD

The NATO phonetic alphabet is quite familiar - Alfa, Bravo, Charlie, Delta, and was widely used by astronauts, being military men, to make sure everyone got the right letters in. But sometimes they came up with their own, to interesting effect, like Jack here. #Skylab50 #SkylabOTD

It's always important to know that you're all talking about the same thing, especially in spaceflight. Even the humble tape could cause some confusion. #Skylab50 #SkylabOTD

Happy Birthday to legendary Robert Crippen!

Any space fans here? Jack Lousma had some stuff to say to us. #Skylab50 #SkylabOTD

Skylab 3 crew got a reminder that their successors were already raring to go up themselves. #Skylab50 #SkylabOTD

It's always a good time when Bob Crippen has a chance to chat up the crew. #Skylab50 #SkylabOTD

Friendly ribbing from one spaceman to another today, ala Pete Conrad, Al Bean and Jack Lousma.#Skylab50 #SkylabOTD

Tonight, Pilot Jack Lousma's home town of Grand Rapids, Michigan. lit it all up for their astronaut son. Jack was well impressed. #Skylab50 #SkylabOTD

Apparently it's a party! #Skylab50 #SkylabOTD

During tonight's status check, the crew discussed the mysterious sounds of Skylab. Changes in temperature made the whole station talk to them, especially at night. #Skylab50 #SkylabOTD

Conversations between the crew and CapCom Richard "Dick" Truly. #Skylab50 #SkylabOTD

The Skylab 3 crew received important news today. #Skylab50 #SkylabOTD

We have news on the most famous mustache in spaceflight! #Skylab50 #SkylabOTD

Sometimes all you needed even on a space station was a nice cleaning rag. The shortage made the crew turn to using their dirty clothes for the purpose. #Skylab50 #SkylabOTD

Al Bean had thoughts for their instructions back on Earth, who had put them through every imaginable scenario in the simulators to make them ready for everything in space. #Skylab50 #SkylabOTD

The Swiss Army Knife is a legendary multipurpose tool. It is no wonder that Skylab's crew found it useful for things like repairing bicycle pedals. #Skylab50 #SkylabOTD

One pleasure of following Skylab day by day is discovering gems like this. Today, the crew was appreciative of engineer Donald R. Bowden, a long-term engineer on the Saturn V rocket and Skylab itself. #Skylab50 #SkylabOTD

The saga of the stolen space suit continues, and the crew of Skylab 3 is all for it. #Skylab50 #SkylabOTD

It's always a good news day for Skylab, when the news is Skylab. #Skylab50 #SkylabOTD

Skylab astronauts got to hear some interesting news about Commander Bean's old moon suit taking an unexpected walk. We'll be trying to find out how this story panned out. #Skylab50 #SkylabOTD
