Antares Return to Flight Set for Magnificent Monday Night Launch – Watch Live

NASA WALLOPS FLIGHT FACILITY, VA – The ‘Return to Flight’ blastoff of Orbital ATK’s upgraded Antares rocket will have to wait one more day to come to fruition with a magnificent Monday night launch – after a technical scrub was called this afternoon, Oct. 16, at NASA’s Virginia launch base due to a faulty cable.

The first Antares rocket liftoff in nearly two years is now being targeted for Oct. 13 on what is sure to be a dazzling nighttime leap from NASA’s Virginia launch base – and potentially offering a thrilling skyshow to millions of US East Coast spectators, if all goes well.

Top NASA and Orbital ATK managers formally approved the launch of the upgraded commercial Antares rocket for next Thursday evening, Oct. 13, on a cargo resupply mission to the International Space Station (ISS). The announcement follows on the heels of a successful joint pre-launch Flight Readiness Review (FRR).

Blastoff of the Orbital ATK Antares rocket is slated for 9:13 p.m. EDT from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility on Virginia’s picturesque Eastern shore.

Antares will carry the Orbital OA-5 Cygnus cargo freighter to orbit on a flight bound for the ISS and its multinational crew of astronauts and cosmonauts.

The launch marks the first nighttime liftoff of the Antares – and it could be visible up and down the eastern seaboard if weather and atmospheric conditions cooperate to provide a spectacular viewing opportunity to the most populated region in North America.

The 14 story tall commercial Antares rocket also will launch for the first time in the upgraded 230 configuration – powered by new Russian-built first stage engines.

For the OA-5 mission, the Cygnus advanced maneuvering spacecraft will be loaded with approximately 2,400 kg (5,290 lbs.) of supplies and science experiments for the International Space Station (ISS).

If Cygnus launches as planned on Oct 13, it is scheduled to arrive at the station on Sunday, Oct. 16. Astronauts will use the space station’s robotic arm to grapple Cygnus at approximately about 6:45 a.m. EDT and berth it to the bottom of the station’s Unity module.

NASA TV will provide live coverage of the launch as well as the rendezvous and grappling activities.

The 2 year lull in Antares launches followed the rockets immediate grounding after its catastrophic failure just moments after liftoff on Oct. 28, 2014 that doomed the Orb-3 resupply mission to the space station – as witnessed by this author.

Orbital ATK’s Antares commercial rocket had to be overhauled with the completely new RD-181 first stage engines following the destruction of the Antares rocket and Cygnus supply ship two years ago.

In light of the grounding of the SpaceX Falcon 9 and Dragon cargo flights following the catastrophic Sept.1 launch pad disaster, and the catastrophic Antares launch failure in Oct. 2014, this Orbital ATK mission becomes more critical than ever to keep that station stocked and fully operational for the resident crews with a reliable American supply train.

Watch for Ken’s continuing Antares/Cygnus mission and launch reporting. He will be reporting from on site at NASA’s Wallops Flight Facility, VA during the launch campaign.

NASA Targets ‘Return to Flight’ of Upgraded Antares for mid- October for Station Resupply

NASA is targeting mid-October for the ‘Return to Flight’ launch of the upgraded Orbital ATK Antares rocket on a cargo mission to resupply the International Space Station (ISS).

In light of the grounding of the SpaceX Falcon 9 and Dragon cargo flights following the catastrophic Sept.1 launch pad disaster, this Orbital ATK mission becomes more critical than ever to keep that station stocked and fully operational for the resident crews.

NASA and Orbital ATK announced that the re-engined Antares will launch during a five-day launch window that opens no earlier than October 9-13, 2016 on the OA-5 Cygnus cargo mission from the Mid-Atlantic Regional Spaceport at Wallops Island on Virginia’s Eastern shore.

“A more specific date will be identified upon completion of final operational milestones and technical reviews,” according to statements from NASA and Orbital ATK.

If Antares launches on Oct. 9, liftoff is set 10:47 p.m. EDT and becomes progressively earlier on succeeding days. The launch time moves up to 9:13 p.m. EDT on Oct. 13.

If the launch takes place during this window, it will mark the first truly nighttime launch for Antares from Virgina.

“The arrival and berthing of Cygnus to the International Space Station will be determined by the exact launch date and in coordination with other space station activities,” says NASA.

For the OA-5 mission, the Cygnus advanced maneuvering spacecraft will carry approximately 2,400 kg (5,290 lbs.) of supplies and science experiments for the International Space Station (ISS).

Under the Commercial Resupply Services (CRS) contract with NASA, Orbital ATK will deliver approximately 28,700 kilograms of cargo to the space station. OA-5 is the sixth of these missions.

Orbital ATK Antares ‘Return to Flight’ ISS Launch Postponed To September For Further Analysis

The ‘Return to Flight’ launch of Orbital ATK’s Antares rocket on a cargo resupply launch for NASA bound for the space station has been postponed for at least another month into September due to the need for further analysis of the revamped booster and other factors.

Today’s announcement by Orbital ATK of a launch delay to mid-September comes barely two weeks before the long hoped for liftoff – which had been scheduled for late afternoon on August 22 from Orbital ATK’s launch base of Virginia’s picturesque eastern shore.

Orbital ATK cited multiple factors for the launch postponement from NASA’s Wallops Flight Facility in a short statement released today, August 10.

“Due to a variety of interrelated factors, including the company’s continuing processing, inspection and testing of the flight vehicle at Wallops Island, and NASA’s scheduling of crew activities on the International Space Station in preparation for upcoming cargo and crew launches, Orbital ATK is currently working with NASA to target a window in the second half of September for the launch of the OA-5 mission,” Orbital ATK announced.

This is the latest in a string of Antares launch delays, running back to the start of 2016.

Furthermore, a new launch date won’t be announced for at least several more weeks.

“A more specific launch date will be identified in the coming weeks,” said Orbital ATK.

Orbital ATK’s Antares commercial rocket had to be overhauled with completely new first stage engines following the catastrophic launch failure nearly two years ago on October 28, 2018 just seconds after blastoff that doomed the Orb-3 resupply mission to the space station.

The goal of the Antares ‘Return to Flight’ mission is to launch Orbital ATK’s Cygnus cargo freighter on the OA-5 resupply mission for NASA to the International Space Station (ISS).

To that end the aerospace firm recently completed a successful 30 second long test firing of the re-engined first stage on May 31 at Virginia Space’s Mid-Atlantic Regional Spaceport (MARS) Launch Pad 0A – as I reported here earlier.

Teams from Orbital ATK and NASA have been scrutinizing the data in great detail ever since then to ensure the rocket is really ready before committing to the high stakes launch.

“Orbital ATK completed a stage test at the end of May and final data review has confirmed the test was successful, clearing the way for the Antares return to flight,” said the company.

“Simultaneously, the company has been conducting final integration and check out of the flight vehicle that will launch the OA-5 mission to ensure that all technical, quality and safety standards are met or exceeded.”

Antares launches had immediately ground to a halt following the devastating launch failure 22 months ago which destroyed the rocket and its critical payload of space station science and supplies for NASA in a huge fireball just seconds after blastoff – as witnessed by this author.

As a direct consequence of the catastrophic launch disaster, Orbital ATK managers decided to outfit the Antares medium-class rocket with new first stage RD-181 engines built in Russia.

The RD-181 replaces the previously used AJ26 engines which failed moments after liftoff during the last launch on Oct. 28, 2014 resulting in a catastrophic loss of the rocket and Cygnus cargo freighter.

The RD-181 flight engines are built by Energomash in Russia and had to be successfully tested via the static hot fire test to ensure their readiness.
