What Makes a Great Countdown?

To hear what goes into a real Mars launch countdown, here’s a great example from the Curiosity rover launch.

We wanted to hear YOUR version!

We asked: if you could do a launch countdown, what would you say? Our suggestions:

  • Get your kids and/or pets involved
  • Role play as a NASA flight director
  • Give us your best announcer voice
  • Send your “bon voyage” and best wishes to Perseverance
  • Cheer, hold up signs, make costumes — you name it!
“Propulsion — Go!”
“Hydraulics — Go!”
“Launch Director is GO.”
