Capitalism in space: Virgin Orbit has determined that a break in the oxygen feed line in its LauncherOne rocket caused the failure during its first orbital test flight in late May.

Speaking at a webinar organized by the Space Generation Advisory Council, an organization for young space industry professionals, Dan Hart said the demonstration mission for the LauncherOne rocket May 25 went well until several seconds after the ignition of the NewtonThree engine that powers the rocket’s first stage. “We had a component break in our engine system. It was a high-pressure feed line,” he said. Liquid oxygen “stopped going into the engine and our flight was terminated.”

The company has performed an investigation and identified what needs to be fixed in the engine to strengthen the components that failed. A second LauncherOne rocket is in final integration right now and will be leaving the factory in the next few weeks while modifications to the engine continue. “We’ll be targeting our next flight before the end of the year,” Hart said.

They need to meet that schedule, as in the past few years they have consistently failed to fly when promised.

Capitalism in space: Virgin Orbit has posted a detailed update on the failure of its LauncherOne rocket on its first launch on May 25.

About 9 seconds after drop, something malfunctioned, causing the booster stage engine to extinguish, which in turn ended the mission. We cannot yet say conclusively what the malfunction was or what caused it, but we feel confident we have sufficient data to determine that as we continue through the rigorous investigation we’ve already begun. With the engine extinguished, the vehicle was no longer able to maintain controlled flight — but the rocket did not explode. It stayed within the predicted downrange corridors of our projections and our Federal Aviation Administration (FAA) launch license as the vehicle fell to the ocean, posing no risk to public safety, no danger our aircrew or aircraft, and no significant environmental impact.

They note that the rocket’s release and engine ignition went as planned, which is for them positive news. They say they their next rocket is being prepared for launch, but do not say when.

I have embedded their video report of the flight below the fold. It does include video of the rocket’s release, ignition, and shut down, but cuts off at that point.

Capitalism in space: Virgin Orbit has announced that it will attempt the first orbital launch of its LauncherOne rocket this coming Sunday, May 24.

The company is targeting Sunday (May 24) for its Launch Demo mission, with a backup opportunity on Monday (May 25). The four-hour window will open each day at 1 p.m. EDT (1700 GMT), Virgin Orbit representatives announced today (May 20).

Launch Demo will be a huge milestone for Virgin Orbit, which has been developing its air-launch system for five years. That system involves a modified Boeing 747 jet called Cosmic Girl and a 70-foot-long (21 meters) rocket known as LauncherOne, which is capable of delivering about 1,100 lbs. (500 kilograms) to a variety of destinations in low Earth orbit.

If the launch succeeds, than Virgin Orbit will stand ready to begin commercial launches later this year.

Capitalism in space: Virgin Orbit yesterday completed the first capture-carry test of LauncherOne with it attached to the company’s 747 loaded with cryogenic materials.

In previous flight tests, the booster’s tanks were filled with water, which is much warmer than LOX.

For this cryogenic test, Virgin Orbit substituted liquid nitrogen for the LOX as a safety precaution. “So, for this end-to-end rehearsal, we’ll have liquid nitrogen — which is very similar in temperature to liquid oxygen, but which would pose less of a risk in case anything were to go wrong despite all of our planning — in our LOX tanks for both stages,” Virgin Orbit wrote in a mission update.

They say this was their last test prior to LauncherOne’s maiden flight. They have not yet set a date for that flight.

This maiden flight was first supposed to happen in 2018, but in that year development of this rocket slowed to a snail’s pace, probably because they had lost a major launch contract.

The contract award only two days ago from the Space Force will likely reinvigorate Virgin Orbit.

My 2016 prediction that Virgin Orbit would make its first operational flight before Virgin Galactic, even though Virgin Galactic had been started development of SpaceShipOne more than a decade earlier, is still holding. The race now appears to be neck-in-neck, as Virgin Galactic claims it will do operational flights this year. We shall see.

Capitalism in space: According to their CEO, the first launch of Virgin Orbit’s LauncherOne rocket is expected to occur in the “coming weeks.”

“We are positioned at the end of the runway in Mojave. Our rocket is married to our 747,” he said. “We’re going through launch rehearsals.”

In an interview after the panel, Hart said that the company was ready to move into operations quickly should that test launch be a success. “If we have a great day, we’re poised to go forward pretty much immediately,” he said. The next LauncherOne rocket is currently “well along” in assembly at the company’s Long Beach, California, factory.

He also admitted that as a demo test flight, that first launch could go sour, and they were prepared for that.

The development of LauncherOne slowed appreciably in the past two years. In July 2018 got their first launch license, and said they would do this launch late that year. It did not happen. Then, in November 2018 they began capture-carry flights, with the expectation they would fly this first launch in 2019. This did not happen either. Worse, in August 2019 it was revealed that the company had lost a major launch contract, the lose of which might explain the slowdown in development.

Despite this slow down, my 2016 prediction that LauncherOne will complete its first commercial flight before Virgin Galactic’s SpaceShipTwo, still looks good, even though SpaceShipTwo began development more than a decade before LauncherOne.

Capitalism in space: Even as it prepares for its first orbital demonstration flight, Virgin Orbit today announced that it is considering development of a third stage that will make the rocket capable of launching planetary cubesat missions.

John Fuller, Virgin Orbit advanced concepts director, said the company is deciding between three “highly energetic third stage” options for LauncherOne that would enable the rocket to launch up to 50 kilograms to Mars or 70 kilograms to Venus. The “Exploration 3-Stage Variant” of LauncherOne would also have the ability to launch around 100 kilograms to the moon or toward Lagrange points, he said.

“What we do is we take that third stage and bring the overall impulse of the vehicle up to a point where we can reach very high energies to launch to cis-lunar, interplanetary or even asteroid targets,” Fuller said Oct. 24 at the 70th International Astronautical Congress here.

The company however has still not flown the rocket, and that first flight is now about a year-plus behind schedule. They say they are preparing for the first orbital mission before the end of year but until it happens there is plenty of room for skepticism.

Capitalism in space: Virgin Orbit has shipped its first LauncherOne rocket to Mohave for final tests prior to its first launch, planned for sometime this year.

Virgin Orbit didn’t give a schedule for completing those tests and performing that orbital flight. Dan Hart, president and chief executive of Virgin Orbit, said at the World Satellite Business Week conference in Paris Sept. 11 that he expected those final tests be completed in a matter of weeks. “It will take a handful of weeks to get through a number of wet dress rehearsals, crew training, and verification of the system,” he said. “We’ll do one flight test with that rocket and then we’ll get to orbit.” He estimated the company would be ready for launch “in the middle of this fall.”

If that first orbital test flight is successful, they hope to do their first operational commercial launch before the end of the year.

My 2016 prediction that a LauncherOne will complete its first commercial launch before SpaceShipOne, continues to look likely, even though SpaceShipOne began development more than a decade before LauncherOne..

Capitalism in space: Virgin Orbit yesterday completed the first capture-carry flight of LaunchOne, flying the rocket attached to the bottom of Cosmic Girl, its 747 launch vehicle.

The flight lasted 80 minutes in total, during which Virgin Orbit’s flight crew assessed the take-off, landing, and low-speed handling and performance of the integrated system.

“The vehicles flew like a dream today,” said Virgin Orbit Chief Pilot Kelly Latimer (Lt. Col, US Air Force, Ret.). “Everyone on the flight crew and all of our colleagues on the ground were extremely happy with the data we saw from the instruments on-board the aircraft, in the pylon, and on the rocket itself. From my perspective in the cockpit, the vehicles handled incredibly well, and perfectly matched what we’ve trained for in the simulators.”

They are aiming to begin commercial flights next year, and appear on schedule. If so, they will jump ahead into the number two spot in the smallsat rocket race, behind Rocket Lab but ahead of Vector.

Capitalism in space: Virgin Orbit has begun fit tests of its LauncherOne rocket attached to its 747 launch vehicle.

This suggests that they are getting close to the first taxi and flight tests of this smallsat rocket, originally promised for the summer that just ended.

I am increasingly confident that my 2016 prediction that Virgin Orbit’s LauncherOne will reach space before Virgin Galactic’s SpaceShipTwo will be correct, even though the former has been in serious development only about four years compared to the latter’s now fifteen year history of no space flights.

Capitalism in space: Virgin Orbit has completed a series of flight tests of the 747 airplane that will be used to launch its LauncherOne smallsat rocket.

The flights of the company’s Boeing 747 aircraft, nicknamed “Cosmic Girl,” were the first since the company installed a pylon on the plane’s left wing that will be used to carry the LauncherOne rocket on future flights of the air-launch system.

The company disclosed few details about the test flights, but flight tracking services such as Flightradar24 list three flights of the aircraft in recent days, most recently Aug. 27, taking off from the Southern California Logistics Airport in Victorville, California. The flights ranged in duration from one and a half to three and a half hours in airspace over the Mojave Desert and over the Pacific Ocean off the California coast.

The company appears to be making progress, though its also appears that their promised first rocket flights are not happening this summer, as previously announced.
