“Cosmic Girl" wykonał ostatnio 3 loty z pylonem.
Przewidziane jest na najbliższe tygodnie rozszerzenie tego typów lotów , potem seria lotów z modelem RN LauncherOne i niewykluczone , że przed końcem roku doczekamy się podjęcia próby orbitalnego testu.

Virgin Orbit performs LauncherOne aircraft flight tests
by Jeff Foust — August 28, 2018

(...) 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 installed the pylon about a month ago, attached to a point on the wing between the fuselage and the inner engine designed to ferry a fifth, non-operational engine. Those test flights went “extremely well,” according to a company official, calling it a “big milestone” as the company.

In a commercial space panel discussion Aug. 1 at a meeting of the Air Line Pilots Association here, Todd Ericson, vice president of safety and flight test at sister company Virgin Galactic said a series of “envelope expansion” test flights of the 747 with the pylon was scheduled for the coming weeks. The company then plans to carry out a series of captive carry test flights with a model of the LauncherOne rocket, culminating in a test where the rocket is dropped.

If successful, those tests would clear the way for a first orbital launch attempt by LauncherOne “by the end of the year,” Ericson said.

Virgin Orbit performs first captive carry flight
by Jeff Foust — November 18, 2018 , Updated 4 a.m. Eastern Nov. 19 with company statement.

WASHINGTON — Virgin Orbit performed the first captive carry flight of its LauncherOne air-launch system Nov. 18, a key testing milestone as the company moves closer to a first flight.

The company’s “Cosmic Girl” aircraft, a Boeing 747 with a pylon added to its left wing to which the LauncherOne rocket attaches, took off from the Southern California Logistics Airport in Victorville, California, shortly after 2 p.m. Eastern, according to flight tracking services. It landed back at the airport 80 minutes later after flying above the high desert region of Southern California, including passing over the Mojave Air and Space Port.

The flight tracking data didn’t specify if the plane was carrying a LauncherOne rocket, but one eyewitness posted video of the plane taking off from the Victorville airport with a rocket attached. A company spokesperson confirmed later Nov. 18 that this was a captive carry flight, the first for Virgin Orbit. (...)

During a captive carry flight, the rocket remains attached to the plane. Virgin Orbit said in a statement last month that “a number” of such captive carry flights are planned, “gathering terabytes of valuable data about aerodynamic performance, structural loading, and more.” That captive carry test program will culminate in a drop test, where the rocket is released in flight from the plane but does not ignite its engine, instead falling to the desert floor.

Barring any technical setbacks, the drop test will be the final step before the first orbital flight of LauncherOne. The company said last month it had already completed manufacturing of that rocket, with two “fully integrated” rocket stages undergoing static-fire tests in Mojave.

The company said in its statement about the captive carry flight that the first orbital flight was now projected to take place in early 2019, with “multiple trips to orbit in the year ahead.” In an interview with CNBC Oct. 9, Richard Branson, founder of the Virgin Group, said he expected the first orbital launch to take place in December or January.
