LAUNCH UPDATE We are GO to launch the #Antares vehicle tonight, Oct. 2, at 9:16 p.m. EDT after a ground software issue scrubbed the launch last night. The issue has since been resolved. The live stream will begin at 8:45 p.m. EDT on NASA TV.

The countdown began on time to begin final preps for tonight's 9:16 p.m. EDT (0116 GMT) blastoff of the 14-story Antares rocket from the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility in Virginia.

This is the second launch attempt for this cargo mission to the International Space Station, after a ground software issue forced an abort during the terminal countdown Thursday night.

The Antares rocket will soon be powered up, and the launch team is going through a checklist of testing to ensure all systems are in good shape. The launch pad is also scheduled to be evacuated of all personnel early in the countdown sequence.

Propellant loading should begin around 90 minutes prior to liftoff.

The first weather briefing in the countdown indicates there is a 90% chance of favorable weather during tonight's five-minute Antares launch window. Weather conditions at launch time are predicted to be mostly clear, with a few clouds at 4,000 feet, winds from the northwest at 4 knots, and a temperature of 56 to 58 degrees Fahrenheit.

The launch team has powered up the Antares launch vehicle to begin systems checks.

[tnt22]

10/03/2020 00:26 Stephen Clark

The launch team has uploaded the optimal launch time and final vehicle mass numbers into the Antares flight computer for today's mission.

The propellant loading timeline sequencer has been initiated, beginning steps to ready the Antares rocket and ground systems for filling of the first stage with liquid propellants later in the countdown.


10/03/2020 00:46 Stephen Clark

These initial preparatory steps include chilldown conditioning of the launch pad's cryogenic propellant lines, purges and other activities. Propellant flows into the Antares rocket's first stage will begin around 90 minutes prior to liftoff.

Chilldown of the liquid oxygen loading system at launch pad 0A is now underway.

[tnt22]

10/03/2020 00:48 Stephen Clark

A team is still at pad 0A near the Antares rocket to work on an technical issue, so some hazardous activities in the countdown are being deferred until later when personnel are clear of the pad.

[tnt22]

10/03/2020 01:07 Stephen Clark

After accomplishing a few last-minute tasks, the Antares pad team is clear of the launch vehicle, allowing the countdown to proceed into radio transmitter checks.

[tnt22]

10/03/2020 01:08 Stephen Clark

The countdown is moving into testing of the Antares rocket's beacon and telemetry transmitters. This will be followed by checks of the vehicle's flight termination system.

[tnt22]

10/03/2020 01:23 Stephen Clark

The launch team is proceeding with testing of the Antares rocket's flight termination system, which would be used to destroy the vehicle if it flew off course after liftoff.

[tnt22]

10/03/2020 01:33 Stephen Clark

The launch team reports satisfactory checks of the Antares rocket's telemetry system.

[tnt22]

10/03/2020 01:44 Stephen Clark

A series of slew, or steering checks, of the Antares rocket's propulsion system has been accomplished.

Antares launch timeline on the NG-14 mission

Northrop Grumman's Antares rocket will deliver a Cygnus supply ship into orbit Thursday to begin a pursuit of the International Space Station.

The rocket's two RD-181 engines will ignite around 3.7 seconds before liftoff from pad 0A at the Mid-Atlantic Regional Spaceport, a complex owned by the state of Virginia at NASA's Wallops Flight Facility.

Launch is timed for 9:38 p.m. EDT Thursday, Oct. 1 (0138 GMT Friday, Oct. 2).

The first stage's two RD-181 engines will power up to 864,000 pounds of thrust and burn for 3 minutes, 18 seconds, then separate from the upper stage's Castor 30XL motor about six seconds later.

The launch, known as NG-14 in Northrop Grumman's station resupply manifest, will be the eighth Antares mission using new, more powerful RD-181 engines, which the company ordered from the Russian engine-builder NPO Energomash to replace decades-old Russian-built AJ26 engines blamed for an Antares rocket crash seconds after liftoff in October 2014.

Once the first stage finishes its job on the NG-14 launch, the Antares rocket's 12.8-foot-diameter (3.9-meter) diameter payload shroud will jettison in two halves at around T+plus 3 minutes, 54 seconds. An interstage adapter that connected the first and second stages will separate at T+plus 3 minutes, 59 seconds.

The launcher's Castor 30XL solid-fueled upper stage will ignite at T+plus 4 minutes, 7 seconds, and generate up to 104,300 pounds of thrust during a burn lasting approximately 2 minutes, 45 seconds. The second stage motor will burn out at approximately T+plus 6 minutes, 52 seconds, then deploy the Cygnus spacecraft at around T+plus 8 minutes, 52 seconds.

The spacecraft's two cymbal-shaped electricity-generating solar arrays will unfurl in a fan-like motion around two hours into the mission, and the ship's thrusters will begin fine-tuning its approach to the space station with a series of course-correction burns, setting up for a laser-guided final approach Sunday, Oct. 4.
