Orbital tentatively realign Antares hot fire to next week following scrub

February 14, 2013 by Chris Bergin

Orbital’s Antares hot fire attempt on Wednesday was scrubbed at T-1.5 seconds, after the vehicle’s flight computer registered a low pressure purge condition ahead of engine ignition. With all other parameters deemed to be nominal throughout the count, a realigned hot fire attempt is likely to take place next week.

Antares Hot Fire Attempt:

Orbital’s new launch vehicle is making progress towards its debut launch, ahead of carrying the company’s Cygnus spacecraft on a demonstration run to the International Space Station (ISS) later this year.

The duo make up half of NASA’s multi-billion dollar Commercial Resupply Services (CRS) contract, awarded to Orbital and SpaceX at the end of 2008. Cygnus has been tasked with eight supply runs to the orbital outpost, while SpaceX will soon carry out the second of 12 cargo missions when they launch SpX-2 (CRS-2) on March 1.

The Antares – a vehicle that started life under the Taurus II call sign – is the first cryogenically powered rocket produced by Orbital Sciences, as well as its largest rocket to date.
