NASA Antares Rocket Explodes at Launch

NASA officials have described the event as a “catastrophic anomaly” but have not pointed to a cause of explosion yet. NASA reports that the team did not experience any warning signs prior to launch that there would be a problem.

The Cygnus spacecraft atop the rocket was carrying 2290 kg (5050 lbs) of cargo for the International Space Station, including the Arkyd-3 satellite.
