Virgin Orbit’s first nighttime launch is DELAYED due to ‘slightly out of bounds’ propellent temperature on LauncherOne rocket and will now take place ‘in the coming days’
Virgin Orbit’s first nighttime launch has been delayed due to a ‘slightly out of bounds’ propellent temperature on its LauncherOne rocket.
The launch, codenamed Straight Up, was set to take place at 10pm PDT Wednesday (6am BST Thursday) but will now happen ‘in the coming days’.
It is set to be the first nighttime launch for the aerospace company, which is part of British billionaire Sir 리처드 브랜슨‘s Virgin Group.
When it finally happens, Straight Up will transport seven satellites for the US Space Force into low Earth orbit, 주위에 310 마일 (500km) above Earth.
The satellites will be blasted into space on a rocket called LauncherOne, which will be unleashed from a jumbo jet from Mojave Air and Space Port in California.

LAUNCHER ONE FLIGHTS
– 할 수있다 25, 2020: Failure

– 유월 30, 2021: 성공
– 일월 13, 2022: 성공
All took place from Mojave Air and Space Port, 캘리포니아
– Early July, 2022 (from Mojave Air and Space Port)
– 구월 8, 2022 (from Spaceport Cornwall)
Straight Up, which is named after a 1988 hit by Paula Abdul, will also be the last Virgin Orbit launch before a historic blast off takes place from Cornwall in September – the first ever UK satellite launch.
It will mark one of the most significant milestones in UK spaceflight since the launch of the British space programme in 1952.
Virgin Orbit announced the Straight Up delay 트위터에서 less than an hour before the launch was expected to happen.
‘We are standing down from today’s launch attempt,’ 회사는 말했다.
‘Our systems are in great health, but our propellant temperature was slightly out of bounds, and out of extreme caution, we are scrubbed for the day.
‘We’re proud of the team for running an extremely professional operation.’
It is unclear exactly when the launch will rescheduled for, although it has been reported that the delay is only likely to be for 24 시간, so it could happen as soon as Friday morning UK time.
As recently as six days ago, Virgin Orbit said it was on track for the scheduled launch at 10pm Wednesday local time, with ‘dress rehearsals complete’.

HOW VIRGIN ORBIT GETS SATELLITES INTO SPACE
TAKE OFF Cosmic Girl, an adapted Boeing 747, takes off from an air and space port, initially in California.
ROCKET DEPLOYMENT At cruising altitude around 35,000 피트, the chief pilot hits the Big Red Button that releases the rocket from the pylon.
FIRST STAGE BURN After a 4-second freefall, the first stage engine, NewtonThree, bursts to life, accelerating the rocket to more than 8,000 시간 당 마일. Once its fuel is spent, the first stage detaches.
FAIRING SEPARATION With LauncherOne now between 310 ...에 745 miles above the Earth’s surface, the fairing pops open, exposing the payload as it nears its destination.
SATELLITE DEPLOYMENT 드디어, with very precise timing, the second stage ejects the satellite into its final orbit.
RETURN TO EARTH Atmospheric drag will eventually pull the second stage back down to Earth, where it burns up in the atmosphere, minimising environmental footprint.
‘Our hardware is in top-notch condition, and the team is performing exceptionally, as we prepare for our first night-time launch,’ Tyler Grinnell, vice president of test, flight and launch for Virgin Orbit, said on June 24.
‘The perspective we’ve gained from each previous launch is really paying off now.
‘Our crews in the sky and on the ground are ready to further our mission of getting our customers’ satellites precisely where they need to go.’
When it eventually occurs, the launch will support the United States Space Force’s STP-S28A mission and carry payloads for the Department of Defense (DOD) Space Test Program (STP).
The seven satellites released will conduct experiments in space-based communications, in-space navigation, and climate change, according to Virgin Orbit.
The firm has already conducted three successful consecutive orbital missions with LauncherOne in 2021 과 2022, the last one taking place 1 월.
All three blasted off from Mojave Air and Space Port, 캘리포니아, but the next one, scheduled for September 8, will launch from Spaceport Cornwall, part of Newquay Airport.
Virgin Orbit uses an eccentric launch method, involving a carrier aircraft, a modified Boeing 747 called Cosmic Girl, and LauncherOne, a two-stage orbital launch vehicle, tucked into Cosmic Girl’s belly.
Once Cosmic Girl is at a high enough altitude – around 35,000 feet – LauncherOne is unleashed.
When at an orbital altitude, LauncherOne deploys the satellites, catapulted into orbit at 8,000 시간 당 마일.

Virgin Orbit is a company within the Virgin Group, the conglomerate founded by Richard Branson in 1970. Virgin Orbit was formed in 2017 to develop the air-launched LauncherOne rocket, launched from Cosmic Girl (this had previously been a project of Virgin Galactic)
Over the last 16 months since January 2021, LauncherOne has already deployed payloads in space for Virgin Orbit’s customers, 포함 NASA and the US Department of Defense.
