Space Shuttle Atlantis
Just a few minuets ago, the space shuttle Atlantis landed safely at Edwards Air Force Base to conclude its 28 mission. Atlantis spent two weeks in space, delivering an addition to the International Space Station. Also, Atlantis brought home one astronaut who set the endurance record for the longest single spaceflight by a woman at 195 days.
Whenever a space shuttle lands, as it crosses from supersonic to subsonic, it emits its signature twin sonic boom. Today the sonic boom sounded at about 12:47 local time. I live about 80 miles form Edwards and approximately 30 seconds after Atlantis made the sonic boom, I heard it standing inside my house. The last time I heard the twin sonic boom was 5 years ago when i was rehearsing my 8th grade promotion. That was the shuttle Endeavour returning from its two week mission to the International Space Station.
