An unmanned NASA-contracted rocket exploded early Tuesday evening along the eastern Virginia coast, causing a huge fireball but no apparent deaths.
"There was failure on launch," NASA spokesman Jay Bolden said. "There was no indicated loss of life."
NASA's mission control is trying to assess what went wrong. The launch director says they must maintain the crash site securely because of security concerns about the equipment on board - saying the rocket had "classified crypto equipment" on board.
According to NASA, the Orbital Sciences Corp.'s Antares rocket and Cygnus cargo spacecraft were set to launch at 6:22 p.m. ET from the Wallops Flight Facility along the Atlantic Ocean. It was set to carry some 5,000 pounds of supplies and experiments to the International Space Station.

A battle of words broke out over the weekend between Kaci Hickox, who returned home from Ebola-ravaged West Africa only to be ordered into quarantine, and Republican governor Chris Christie. The nurse told CNN that her "basic human rights have been violated" and that Christie himself was responsible.
CDC officials stopped short of issuing nationwide quarantine rules, instead issuing new guidelines that set levels of risk for returning travelers - guidelines to help those states that are currently monitoring travel from West Africa.
But, should health care workers coming from West Africa be quarantined?
In an interview with CNN's Erin Burnett, Dr. Rick Sacra says a mandatory quarantine would be a 'disincentive' for people to travel to West Africa to treat Ebola patients.
