Whenever I’m over at the Mojave Air and Space Port, I’ve always felt a little sad when I catch a glimpse of Northrop Grumman’s Stargazer aircraft.
The last Lockheed L-1011 Tristar still flying today, the modified passenger aircraft’s main task is to air launch satellites aboard the Pegasus XL rocket carried under its fuselage. Since the rocket isn’t much in demand, the gap between launches can last for years.

Virgin Orbit’s Cosmic Girl 747 aircraft conducted a low-speed taxi test down runway 12-30 at the Mojave Air and Space Port on Thursday afternoon.

The aircraft taxied down the runway, turned around and returned. The Boeing 747 was then towed back to a concrete pad where it has sat for the last several weeks undergoing preparations for a taxi test and captive carry flight.

Virgin Orbit has said that it needed to do a taxi test with a full fueled LauncherOne prior to doing a captive carry flight. It is not clear whether the booster was fueled. However, a hazardous operations notice to airmen (NOTAM) was not posted prior to the taxi test.

LauncherOne is designed to orbit small satellites by air launching them over the ocean. A flight test of the booster is scheduled for later this year.

A group of original shareholders in the defunct Firefly Space Systems have accused co-founder and CEO Tom Markusic of fraudulently conspiring with Ukrainian billionaire Maxym Polyakov to force the rocket company into bankruptcy in 2017 and reconstitute it under a nearly identical name without giving them any stake in the new venture.
Markusic “betrayed the trust of his original co-founders and investors and committed fraud to cut them out of his aerospace company. Instead of managing the operations of the Original Firefly, a revolutionary rocket company with endless potential, Markusic schemed with…Maxym Polyakov…to rob Plaintiffs of their investments and form a new company called Firefly Aerospace, Inc. (the ‘New Firefly’),” the plaintiffs said in a lawsuit.

CAPE CANAVERAL AIR FORCE STATION, Fla. (NASA PR) — After successfully launching Thursday night, NASA’s Ionospheric Connection Explorer (ICON) spacecraft is in orbit for a first-of-its-kind mission to study a region of space where changes can disrupt communications and satellite orbits, and even increase radiation risks to astronauts.

Reuters has confirmed reports that Parabolic Arc has been hearing for months here in Mojave: Stratolaunch’s goose is cooked.
Stratolaunch Systems Corporation, the space company founded by late billionaire and Microsoft Corp co-founder Paul Allen, is closing operations, cutting short ambitious plans to challenge traditional aerospace companies in a new “space race,” four people familiar with the matter said on Friday….
[Parent company] Vulcan has been exploring a possible sale of Stratolaunch’s assets and intellectual property, according to one of the four sources and also a fifth person….
The decision to set an exit strategy was made late last year by Allen’s sister, Jody Allen, chair of Vulcan Inc and trustee of the Paul G. Allen Trust, one of the four people and the fifth industry source said.
Jody Allen decided to let the carrier aircraft fly to honor her brother’s wishes and also to prove the vehicle and concept worked, one of the four people said.
NASA and Northrop Grumman have completed a launch readiness review for the early Wednesday morning launch of the space agency’s Ionospheric Connection Explorer (ICON) satellite mission. There are no technical issues being worked at this time.
ICON will be launched by Northrop Grumman’s Pegasus XL rocket which will be carried aloft by the L-1011 Stargazer aircraft taking off from the Skid Strip at Cape Canaveral Air Force Station in Florida.
The ICON satellite mission 90-minute launch window opens at 3 a.m. on Wednesday, Nov. 7. Release from the Stargazer is anticipated for 3:05 a.m. ICON is designed to study the dynamic zone high in the atmosphere where terrestrial weather from below meets space weather from above.
WASHINGTON (NASA PR) — NASA and Northrop Grumman will hold a Launch Readiness Review early next week at NASA’s Kennedy Space Center in Florida to ensure preparations are continuing on track for the launch of the agency’s Ionospheric Connection Explorer, or ICON, satellite.

Wired has an entertaining story by Steven Levy about what Paul Allen and the team at Scaled Composites have been doing with Stratolaunch, whose enormous carrier plane nicknamed the Roc but also know as Composite Goose, Carbon Goose, Birdzilla and Stratosaurus.
SEATTLE, Wash. – August 20, 2018 (Stratolaunch PR) – Stratolaunch announces today its new family of launch vehicles that will enter regular service starting in 2020. The company’s unique air-launch system will use the world’s largest aircraft as a mobile launch platform, capable of deploying launch vehicles that will carry satellites to multiple orbits and inclinations on a single mission. With these new vehicles, Stratolaunch is poised to make access to space convenient, affordable, and routine.

Stratolaunch emerged from its hangar over the weekend to soak up some California sun. Engineers took the giant, twin fuselage carrier aircraft outside for some tests.

The announced plan was to conduct some taxi tests on Runway 12/30. The plane didn’t make it that far. Engineers put the airplane through a series of fueling, fueling, full-power engine and communication tests.

The aircraft will begin by launching Pegasus XL boosters, which are produced by Northrop Grumman Innovation Systems.

The company is also working on a medium launcher that expected to debut in 2021. There are not a lot of details about the project, which is under the direction of Vice President of Propulsion Jeff Thornburg.

I caught a glimpse of the aircraft from Highway 14 during my return from the Small Satellite Conference in Utah. I was probably five miles away at the time, but the thing still looked massive sitting there next to the hangar.
NASA and Northrop Grumman have postponed the launch of the agency’s Ionospheric Connection Explorer (ICON) satellite. ICON, which will study the frontier of space, was targeted to launch on a Pegasus XL rocket June 14 from the Kwajalein Atoll in Marshall Islands.
During a ferry transit, Northrop Grumman saw off-nominal data from the Pegasus rocket. While ICON remains healthy, the mission will return to Vandenberg Air Force Base in California for rocket testing and data analysis. A new launch date will be determined at a later date.

At least 10 launches are planned worldwide this month. The launches include crew and cargo missions to the International Space Station and the first commercial flight of Rocket Lab’s Electron booster. Orbital ATK’s Pegasus XL will launch NASA’s Ionospheric Connection Explorer (ICON) from the Marshall Islands on June 14.
China got June off to a successful start on Saturday with the launch of the Gaofen-6 remote sensing satellite aboard a Long March 2D rocket from the Jiuquan Satellite Launch Center.
SpaceX is up next, with an early morning launch on Monday morning. A Falcon 9 is set to launch the SES 12 communications satellite from Cape Canaveral in Florida. The four-hour launch window opens at 12:29 a.m. EDT (0429 GMT). The company has no plans to recover the previously used first stage.
The current launch schedule is below. View updates here.

Problems with its launch vehicle and range schedule conflicts have caused a year-long in the launch of a new NASA spacecraft that will study the Earth’s ionosphere, according to a new Government Accountability Office (GAO) assessment.
The June 2017 launch date for the Ionospheric Connection Explorer (ICON) satellite was delayed after two of the three stages of the Pegasus XL’s launch vehicle were involved in a transport accident, the GAO found. The stages were returned to Orbital ATK’s facility for inspection and testing, but no damage was found.
