The payload fairing at the top of Gilmour Space\u2019s first Eris rocket was supposed to deploy a few minutes after lifting off from northeastern Australia. Instead, the nose cone fell off the rocket hours before it was supposed to leave the launch pad Thursday.<\/p>\n

Gilmour, the Australian startup that developed the Eris rocket, announced the setback in a post to the company\u2019s social media accounts Thursday.<\/p>\n

\u201cDuring final launch preparations last night, an electrical fault triggered the system that opens the rocket\u2019s nose cone (the payload fairing),\u201d Gilmour posted on LinkedIn. \u201cThis happened before any fuel was loaded into the vehicle. Most importantly, no one was injured, and early checks show no damage to the rocket or the launch pad.\u201d<\/p>\n

Gilmour was gearing up for a launch attempt from a privately owned spaceport in the Australian state of Queensland early Friday, local time (Thursday in the United States). The company\u2019s Eris rocket, which was poised for its first test flight, stands about 82 feet (25 meters) tall with its payload fairing intact. It\u2019s designed to haul a payload of about 670 pounds (305 kilograms) to low-Earth orbit.<\/p>\n

While Gilmour didn\u2019t release any photos of the accident, a company spokesperson confirmed to Ars that the payload fairing \u201cdeployed\u201d after the unexpected electrical issue triggered the separation system. Payload fairings are like clamshells that enclose the satellites mounted to the top of their launch vehicle, protecting them from weather on the launch pad and from airflow as the rocket accelerates to supersonic speeds. Once in space, the rocket releases the payload shroud, usually in two halves. There were no satellites aboard the rocket as Gilmour prepared for its first test flight.<\/p>\n

This was unusual<\/h2>\n

Payload fairing problems have caused a number of rocket failures, usually because they don\u2019t jettison during launch, or only partially deploy, leaving too much extra weight on the launch vehicle for it to reach orbit.<\/p>\n

Gilmour said it is postponing the Eris launch campaign \u201cto fully understand what happened and make any necessary updates.\u201d The company was founded by two brothers\u2014Adam and James Gilmour\u2014in 2012, and has raised approximately $90 million from venture capital firms and government funds to get the first Eris rocket to the launch pad.<\/p>\n

The astronauts on NASA\u2019s Gemini 9A mission snapped this photo of a target vehicle they were supposed to dock with in orbit. But the rocket\u2019s nose shroud only partially opened, inadvertently illustrating the method in which payload fairings are designed to jettison from their rockets in flight.<\/p>\n

The Eris rocket was aiming to become the first all-Australian launcher to reach orbit. Australia hosted a handful of satellite launches by US and British rockets more than 50 years ago.<\/p>\n

Gilmour is headquartered in Gold Coast, Australia, about 600 miles south of the Eris launch pad near the coastal town of Bowen. In a statement, Gilmour said it has a replacement payload fairing in its factory in Gold Coast. The company will send it to the launch site and install it on the Eris rocket after a \u201cfull investigation\u201d into the cause of the premature fairing deployment.<\/p>\n

\u201cWhile we\u2019re disappointed by the delay, our team is already working on a solution and we expect to be back at the pad soon,\u201d Gilmour said.<\/p>\n

Officials did not say how long it might take to investigate the problem, correct it, and fit a new nose cone on the Eris rocket.<\/p>\n

This setback follows more than a year of delays Gilmour blamed primarily on holdups in receiving regulatory approval for the launch from the Australian government.<\/p>\n

Like many rocket companies have done before, Gilmour set modest expectations for the first test flight of Eris. While the rocket has everything needed to fly to low-Earth orbit, officials said they were looking for just 10 to 20 seconds of stable flight on the first launch, enough to gather data about the performance of the rocket and its unconventional hybrid propulsion system.<\/p>\n","protected":false},"excerpt":{"rendered":"
