Unmanned private cargo rocket explodes after launch: NASA

The cargo spacecraft was set to carry some 5,000 pounds of supplies and experiments to the International Space Station

An unmanned private rocket contracted by NASA to carry cargo into the space has exploded seconds after its launch along the eastern Virginia coast of the US.

"There was failure on launch. There was no indicated loss of life," NASA spokesman Jay Bolden said after the Orbital Sciences Corporation's Antares rocket and Cygnus cargo spacecraft blew up yesterday evening soon after its launch at 6:22 pm (local time) from the Wallops Flight Facility along the Atlantic Ocean.

"There was significant property and vehicle damage. Mission control is trying to assess what went wrong," Bolden said.

It was set to carry some 5,000 pounds of supplies and experiments to the International Space Station, the space agency said adding that failure occurred six seconds after launch.

The US President Barack Obama was immediately briefed by his officials, the White House said.

"This evening the President was briefed on the launch failure of the Antares rocket in Wallops, Virginia. The President was briefed by White House Deputy Chief of Staff Anita Decker Breckenridge and will continue to get updates as more information becomes available," the White House Principle Deputy Press Secretary Eric Schultz said.

According to NASA's emergency operations officials, there were no casualties and property damage was limited to the south end of Wallops Island. Orbital has formed an anomaly investigation board, which will work in close coordination with all appropriate government agencies, to determine the cause of yesterday's mishap.

According to the space agency's statement, the launch of Antares rocket was initially scheduled for Monday but the attempt was scrubbed because a boat was inside the range safety zone southwest of the launch pad.

Orbital Sciences Corporation said the Antares rocket launch from NASA's Wallops Flight Facility was catastrophic failure.

"It is far too early to know the details of what happened," said Orbital's Executive Vice President and General Manager of its Advanced Programs Group Frank Culbertson.

"As we begin to gather information, our primary concern lies with the ongoing safety and security of those involved in our response and recovery operations. We will conduct a thorough investigation immediately to determine the cause of this failure and what steps can be taken to avoid a repeat of this incident," Culbertson said.

"As soon as we understand the cause we will begin the necessary work to return to flight to support our customers and the nation's space program," he added.

According to CNN, video showed the rocket rising into the air for a few seconds before an explosion. It then plummets back to Earth, causing more flames as it hits the ground.
