Ground sensors leave rockets stuck on Earth

WALLOPS ISLAND, Va. — A Northrop Grumman rocket carrying supplies for astronauts aboard the International Space Station (ISS) failed to get off the launch pad in Virginia on Thursday evening, marking the third scrubbed American launch in less than 24 hours.

A computer called an automatic halt to the launch of the Antares booster at 2 minutes 40 seconds before the planned liftoff at 9:43 p.m. EDT. The rocket is carrying a Cygnus resupply ship with cargo bound for ISS.

Sensors Result in Delta IV Heavy, Falcon 9 Launch Scrubs

Launches of Delta IV Heavy and Falcon 9 rockets from Florida’s Space Coast were aborted with only seconds to go before liftoff less than 10 hours apart.

The countdown of an United Launch Alliance (ULA) Delta IV Heavy was stopped 7 seconds before a planned 11:54 p.m. launch on Wednesday after a sensor detected an unidentified fault. Crews safed the vehicle on its launch pad at the Cape Canaveral Air Force Station.

The massive rocket is carrying the NROL-44 spy satellite for the National Reconnaissance Office. ULA has not set a new launch date.

It was the sixth scrub or launch delay for the ULA booster since Aug. 27. Five of the delays occurred due to technical problems, the other resulted from weather.

Less than 10 hours later, an “out of family” ground sensor aborted the countdown of SpaceX’s Falcon 9 rocket from NASA’s Kennedy Space Center only 18 seconds before a planned 9:17 a.m. EDT liftoff.

The booster is carrying 60 spacecraft for the company’s Starlink satellite broadband constellation. SpaceX has not announced a new launch date for the flight.

Delta IV Heavy Launch Scrubbed

CAPE CANAVERAL, Fla., Sept. 29, 2020 ULA PR) – The launch of the United Launch Alliance Delta IV Heavy NROL-44 mission has been scrubbed. The local weather resulted in a significant delay to pre-launch preparations including the roll of the Mobile Service Tower (MST).

When the MST roll began we discovered a hydraulic leak in the ground system required to move the tower which needs further evaluation. Subsequent weather will prevent the team from moving forward with tonight’s attempt.

Launch is now scheduled for 11:54 p.m. EDT on Wed., Sept. 30, 2020.

Delayed Delta IV Heavy Launch Rescheduled for Sept. 26

CAPE CANAVERAL AIR FORCE STATION, Fla. (ULA PR) – The launch of a United Launch Alliance (ULA) Delta IV Heavy rocket carrying the NROL-44 mission for the National Reconnaissance Office is planned for Sept. 26, 2020. The launch period is 12:01-1:35 a.m. EDT.

The team has reviewed all data and ground support equipment and determined that a ground system regulator internal component failure was the cause of the on-pad abort.

Out of an abundance of caution all three regulators associated with each of the three common booster cores are being replaced and retested.

Delta IV Heavy Performs Spectacularly Unnerving Nighttime Abort

by Douglas Messier
Managing Editor

CAPE CANAVERAL AIR FORCE STATION, Fla. — A Delta IV Heavy booster carrying a classified reconnaissance satellite experienced a nail biting abort early Saturday morning as flames licked at the bottom of the giant rocket.

United Launch Alliance (ULA) said the rocket’s automated control system aborted the launch at T minus 3 seconds. The engines on the Delta IV Heavy’s first-stage core and its two side boosters never ignited, the company said.

The abort occurred after the Delta IV Heavy’s radially outward firing initiators (ROFI) had begun firing as planned at T minus 15 seconds. The firing engulfed the bottom of the booster in flames, which is a normal occurrence.

Engineers safed the vehicle and began unloading propellant as a scrub was called. The cause of the abort is unclear, but ULA said it would take a minimum of seven days to recycle the launch.

The rocket’s payload was the NROL-44 satellite for the National Reconnaissance Office. The payload is believed to be a signal intelligence gathering satellite.

It’s not known whether the abort will impact SpaceX’s plans to launch two Falcon 9 rockets on Sunday from a nearby pad at Cape Canaveral Air Force Station and Pad 39A at the adjoining Kennedy Space Center.

A Whole Bunch of Launches Scheduled — Again

Bored beyond tears due to the lockdown? Got nothing to do and nowhere to go? Only reruns on the tube?

Stay home, grab some beers, and fire up that computer. There’s a whole bunch of launches on the schedule over the next four days. ULA, Rocket Lab, SpaceX, Astra and Arianespace are all back in action with six launches from three countries.

SpaceX will attempt two launches on the same day from Florida on Sunday. The company might also attempt a hop of its sixth Starship prototype this weekend. The timing for that is uncertain.

Remember: launches are subject to change without notice. And wagering is strictly prohibited.
