NASA's Orion Exploration Flight Test 1 (EFT-1) is slated to launch in 2014. An unmanned Orion Multi-Purpose Crew Vehicle (MPCV) will take flight from Cape Canaveral, Florida, propelled by a Delta IV Heavy Rocket. It will orbit the earth twice before returning to Earth at high velocity.
The EFT-1 Orion MPCV was initially built at Lockheed Martin's New Orleans-based Michod Assembly Facility. Construction will wrap up at the Kennedy Space Center.
Today's two part trivia question concerns the reentry speed and temperature of the capsule.
Will the unmanned EFT-1 Orion return home at:
- 10,000 miles per hour
- 15,000 miles per hour
- 20,000 miles per hour
- 25,000 miles per hour, or
- 30,000 miles per hour?
Will the highest temperatures be:
- 451 degrees Fahrenheit
- 1,200 degrees Fahrenheit
- 2,700 degrees Fahrenheit
- 3,200 degrees Fahrenheit
- 4,000 degrees Fahrenheit?
Answer: The Orion will (literally) rocket home at an astounding 25,000 miles per hour, as it endures temperatures up to 4,000 Fahrenheit. Batten down the hatches!
