Faster than a speeding bullet

The International Space Station is speeding around Earth at about 17,500 mph. That’s 25 times the speed of sound. That’s “Mach 25” in astronaut language.

Pilot Troy Asher let me sit in the rear seat of a NASA F-15 that made a sonic boom going Mach 2!

After he completed the sonic boom maneuver, he descended to a lower altitude to do a low-pass over the crowd standing out in front of NASA’s Armstrong Flight Research Center, and then shot up vertically into the deep blue sky. Sonic booms are really loud, and NASA’s working on technology to make them quieter. (Credit: Mary Ann Harness and Troy Asher)
