Astronaut Chris Hadfield
Last night, an unmanned Antares rocket carrying more than 5,000 pounds of cargo to the International Space Station exploded in a huge fireball seconds after liftoff. No one was hurt, but in addition to damage to the launch pad, NASA lost tons of supplies, including equipment and food for astronauts.
Video also shows the center core which crashed upon return due to failure to reignite some of the engines.
