Virgin Orbit's big demonstration launch doesn't make it to space

  Virgin Orbit's big demonstration launch doesn't make it to space Cosmic girl took off, but LauncherOne didn't make it to orbit.The company's modified 747, Cosmic Girl, flew over the Pacific Ocean off California with the LauncherOne rocket attached to its belly and dropped it as planned, but then something went wrong.

A rocket dropped at 10,000 meters above sea level by a wide-body aircraft, and which then spins in orbit: the young Virgin Orbit company failed on Monday in its first attempt to prove its technology, off the coast of California.

"The mission ended soon after the flight started," Virgin Orbit tweeted.

The space company founded in 2012 by British billionaire Richard Branson wants to offer a flexible and fast launch service to operators of small satellites (300 to 500 kg), a booming market.

Virgin Orbit's rocket does not take off vertically. Instead, the 21-meter-long craft, called LauncherOne, is hung under the left wing of an old, emptied and converted Boeing 747. The plane was named Cosmic Girl.

Virgin Orbit's first launch demo takes place this weekend

  Virgin Orbit's first launch demo takes place this weekend Virgin Orbit is finally ready to try a proper launch demo. The spaceflight outfit now expects the launch demo mission to take place on either May 24th or May 25th between 1PM and 5PM Eastern each day. If there’s enough of a launch window, the Cosmic Girl carrier aircraft will release LauncherOne over the Pacific, where the rocket will fire its engine in mid-air for the first time. It will sustain that flight for as long as possible and deploy a payload in orbit if successful, Virgin said. Virgin Orbit's Cosmic Girl releases LauncherOne The company is aware this is risky.

(AP) — Richard Branson's Virgin Orbit postponed its first space launch Sunday due to a technical Virgin Orbit 's rocket is carried beneath the wing of a Boeing 747 that will take off from Mojave Air The rocket will be released and its motor will ignite a few seconds later to propel a dummy satellite

Virgin Orbit was supposed to launch a rocket from a Boeing 747 rocket on Sunday but the test was scuppered by a technical issue. The Virgin Galactic spinoff had been hoping to achieve the first full demonstration of its mid-air launch system that’s designed to deploy small satellites in low-Earth orbit .

Once at altitude, the aircraft drops the rocket, which ignites its engine in order to gain speed, reach space and place its payload in orbit.

The initial phase went well on Monday, according to Virgin Orbit. Cosmic Girl took off from Mojave Airport in the Californian desert, where many space companies are based, and then the plane flew to the area designated for release, over the Pacific off Los Angeles.

"Cosmic Girl has dropped LauncherOne!" tweeted the company.

But three minutes later, the company wrote: "We confirmed a correct release by the aircraft. But the mission ended soon after the start of the flight. Cosmic Girl and our crew are fine and are returning to base" .

Later, Virgin Orbit gave more details.

"LauncherOne maintained its stability after the release, and we started the engine of our first stage, NewtonThree. An anomaly occurred in the first phase of the flight. We will know more when our engineers have analyzed the mountain of data saved today ".

Virgin Orbit is ready to test its plane-launched space rockets

  Virgin Orbit is ready to test its plane-launched space rockets Virgin Orbit is ready for its first launch after successfully completing an end-to-end test proving that its carrier aircraft, Cosmic Girl, can ferry rockets to the skies for takeoff. The Virgin Group company, which aims to provide launch services for small satellites, sent Cosmic Girl over California with a LauncherOne rocket strapped under its wing. Virgin Orbit loaded the rocket’s tanks with water in previous tests, but this time, it filled those tanks with liquid nitrogen. Virgin Orbit The water in previous tests was over 300 degrees Fahrenheit warmer than the liquid oxygen those tanks would carry for actual launches.

Virgin Orbit held a press briefing on Saturday hosted by CEO Dan Hart and VP of Special Projects Will Pomerantz. Virgin Orbit expects to begin fueling the rocket very early on Sunday morning, and The whole point of the launch is to gather more data for ensuring that each part of the process works

Richard Branson’s Virgin Orbit postponed its first space launch Sunday due to a technical problem. Virgin Orbit ’s rocket is carried beneath the wing of a Boeing 747 that will take off from Mojave Air and Space Port in the desert north of Los Angeles and fly out over the Pacific Ocean.

The second rocket is already in production, she added. The nature of the "anomaly", a euphemism often used in the space industry to designate an explosion, is unknown.

This was a test flight, and Virgin Orbit was careful to warn before that it was "the most complex thing we have ever attempted. The first few seconds after release are the most important ".

The concept of an airborne launch is not new. The Pegasus rocket, from the Northrop Grumman group, has existed since the 1990s. But Virgin Orbit intends to offer a less expensive solution.

An airborne launch is more flexible than a vertical launch, since in theory, an airport runway is enough to launch, instead of a space launch pad.

Richard Branson founded another space company called Virgin Galactic, which uses a similar concept but aims to transport tourists, not satellites, for a few minutes in weightlessness, more than 80 km above the surface.

The start of these space tourism flights has been announced many times by Mr. Branson, for the summer of 2019, and most recently for the summer of 2020.

Interstellar is still struggling to put private rockets in space .
Japan’s budding private spaceflight industry is still struggling, even with some early signs of success. Interstellar Technologies’ MOMO-5 sounding rocket failed to reach space after its launch from Hokkaido early on June 14th. The engine was “manually stopped in an emergency” about 70 seconds into the flight, the company said. Interstellar pinned the flaw on a swinging “attitude angle” that threatened the launch’s safety, and suspected that a damaged nozzle was to blame. You can see hints of this in the Necovideo Visual Solutions clip below — the nozzle appeared to have shed debris early into the launch, and the rocket lost control soon afterward.
