This iconic photograph is still considered one of the most-terrifying space photos to date. Astronaut Bruce McCandless II NASA STS-41B Mission, February 1984, became the first human being to perform spacewalk without a safety tether linked to a spacecraft. He floated completely untethered in space

    What was the backup plan? Did they have a tether and somebody suited up ready to go out and snag him?

    Nevertheless, if some failure somehow jetted him off in some direction he couldn’t stop I guess that would be it.

    I don’t know why it would be terrifying. The plan was that, if anything happened to the MMU, to simply fly the Shuttle over and pick him up.

  3. I wouldn’t strap myself into the giant explosive death trap required to get those people into orbit in the first place. Some people’s risk tolerance is off the charts.

  4. And this is the historic moment when the word “Yeet” is properly defined

    The guy has massive balls btw… respect 🫡

  5. I don’t know if it’s this space walk or the couple times they did it on Apollo 40,000 miles from the moon and 200,000 miles from Earth! Granted the Apollo they were connected but that is a long way from anything!

  6. The balls on that guy. I’d guess basically being robbed at gunpoint is a joke after you do this.

  7. I’ve always considered this to be the bravest mission of aviation history. I never understood why it never carried the fame of other feats.
