Antares rocket explodes at Nasa base seconds after launch Antares rocket explodes at Nasa base seconds after launch
(about 3 hours later)
A rocket carrying supplies for the International Space Station exploded six seconds after it was launched at Nasa’s Wallops Flight Facility in Virginia Tuesday night, sending a massive fireball into the sky. The company behind a resupply mission to the International Space Station that ended in a spectacular explosion over a Virginia launchpad has defended the use of ageing Soviet rockets amid growing questions over Nasa’s reliance on private contractors to fill gaps in the US space program.
The rocket, known as the Antares, carried an unmanned cargo ship loaded with 5,000 pounds of supplies such as food, tools, parts and experiments. It was also carrying classified equipment, according to the private company that built it. Hundreds of millions of dollars worth of equipment, ranging from “classified cryptographic” gear to school science experiments, was destroyed in a giant fireball on Tuesday evening after technicians detonated a self-destruct mechanism six seconds after launch because of a “catastrophic” equipment failure.
The launch had already been once delayed after a sailboat entered its range on Monday night. Tuesday’s weather made for good launch conditions of clear skies and light winds, and it’s unclear what could have disrupted the launch and caused the explosion. Though stressing the exact cause of the failure was unknown, an executive at Orbital lamented the lack of more modern alternatives to its rocket engines, which were built in the late 1960s and early 1970s with the failed aim of putting Soviet cosmonauts on the moon.
A Nasa spokesperson told CNN there was “No indicated loss of life [but] significant property and vehicle damage.” “When you look at it there are not many other options around the world in terms of using power plants of this size, certainly not in this country, unfortunately,” Frank Culbertson, Orbital’s executive vice-president, said after the crash.
The spacecraft was carrying “some classified cryptographic equipment, so we do need to maintain the area around the debris in a secure manner,” said Mike Pinkston, the Antares program manager for the commercial spaceflight company Orbital Science, quoted by Reuters. He also indicated the problem involved failures of the first stage of the Antares rocket, powered by a refurbished Aerojet engine left over from the NK-33 program when the Soviet Union abandoned its moonshot.
To guard against the dangers of a failed launch, the Nasa facility maintains a launch hazard area of about 1,400 square miles around the site. “The asset stopped, there was some, let’s say, disassembly of the first stage, after which it fell to earth,” said Culbertson, in a deadpan description of an explosion that could be seen for miles and terrified observers.
Orbital Science, which has a $1.9bn contract with Nasa to make eight missions to ferry supplies to the International Space Station, would have completed its third delivery with this launch. Since the US space agency retired its fleet in 2011, private companies and cooperation with its Russian counterpart have assisted with missions into space. The technology has been ridiculed by commercial rivals but used regularly by Orbital to resupply the ISS in recent years, despite growing criticism in Congress of Nasa’s reliance on commercial partners to maintain a human presence in space.
“Their rocket honestly sounds like the punchline to a joke,” said Elon Musk, founder of rival SpaceX, in an interview in 2012. “It uses Russian rocket engines that were made in the 60s. I don’t mean their design is from the 60s — I mean they start with engines that were literally made in the 60s and, like, packed away in Siberia somewhere.”
Amid growing questions over the technology on Tuesday night, Culbertson insisted its age could also be an advantage but said Orbital would carry out an urgent inquiry to determine the cause of the latest failure before launching any further missions.
“The history of this engine has been well documented. Basically this was an engine that was designed to carry cosmonauts to the moon,” he said. “A number of them were bought by Aerojet to be refurbished and Americanised. It’s an extensively tested engine, very robust and rugged.
There has been a vehicle anomaly. We will update as soon as we are able.There has been a vehicle anomaly. We will update as soon as we are able.
Orbital said the space craft suffered a “catastrophic failure” at 6.22pm ET. “It is far too early to know the details of what happened,” said. Frank Culbertson, Orbital’s executive vice president and general manager of its advanced programs group.“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. “We don’t know whether the engine was involved in this or not and that’s something we will try to determine as quickly as possible.
Astronauts on the space station, who watched the launch and were said by Nasa to be “disappointed” at the outcome, will now have to rely on supplies from a Russian launch planned on Wednesday.
Nasa said it would also be reordering the manifest on a separate SpaceX mission due next month to make sure necessary supplies reached the crew before a safety buffer runs out in March.
The accident is likely to have caused extensive damage to Nasa Wallops Flight Facility in Virginia and its director, Bill Wrobel, urged members of the public to be cautious in approaching hazardous wreckage near the site. He reported no injuries from the explosion itself.
Mike Pinkston, the Antares program manager for Orbital Science, told Reuters that the spacecraft had been carrying “some classified cryptographic equipment, so we do need to maintain the area around the debris in a secure manner”.
The rocket was propelling an unmanned cargo ship loaded with 5,000lb (2,200kg) of supplies such as food, tools, parts and experiments.
The launch had already been delayed once after a sailboat entered its range on Monday night. Tuesday brought good launch weather, with clear skies and light winds.

Orbital said parts of the mission were covered by insurance and the rocket alone had been worth $200m.

“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.”“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.”
