Rocket Report: Water-propulsion tests promising, Senate shows EUS the money

Enlarge / The Rocket Report is published weekly.Arianespace

Welcome to Edition 2.16 of the Rocket Report! It's been a busy week in space, with the launch of the first person from the United Arab Emirates as well as the final launch of a venerable Russian rocket. By my favorite story this week is a recollection by Wayne Hale about one contingency NASA never had to put in place with the space shuttle—a crew member riding home in the payload bay.

Blue Origin to conduct two more uncrewed test flights. The company expects to fly its New Shepard space tourism rocket at least two more times before it puts the first people on board, chief executive Bob Smith said this week. This probably will necessitate a slip into 2020 for the first crewed flights, CNBC reports.

What is driving the delays? … "It's really the robustness of our entire system. It's not one individual thing that's driving [these delays]," Smith said. "It's us being cautious and thorough with the total systems we need to verify." It's understandable that a company flying people into space would be cautious. Any accidents would undoubtedly put a damper on customer enthusiasm. (submitted by danneely and Ken the Bin)

Virgin Orbit ships rocket to launch site. Virgin said this week that it has shipped the rocket that will fly its first mission into space from the company's factory in Long Beach. At its test site in Mojave, the company says it will begin the rocket's launch campaign. A launch could come late in 2019, provided testing goes well.

Off to the skies … "In the coming weeks, we'll run through a number of critical exercises, including loading and fueling with our mobile ground-support equipment," Virgin said. "We are prepping and practicing, making sure we know how to do everything we could conceivably ever need to do. Then, it's off to the skies—first for a captive carry flight, and then for the launch itself." We're eager to see LauncherOne take to the skies. (submitted by Unrulycow)

Firefly releases updated Payload User's Guide. At first glance, the document appears to contain few significant changes. The Alpha rocket, with a maximum capacity of 1 ton to low Earth orbit, is still being offered to customers for $15 million a launch. The guide also provides information about the larger Beta rocket under development, but it does not provide a price.

Ongoing stage tests … Meanwhile, Firefly has continued to conduct a series of stage tests for the Alpha vehicle. The company indicated last week that it had put a full cluster of four Reaver 1 engines on a test stand in Texas, in the same configuration as for an Alpha launch. The first Firefly mission now appears likely to launch sometime during the first quarter of 2020 from Vandenberg Air Force Base. (submitted by Unrulycow)

Water plasma propulsion shows promise. Silicon Valley startup Momentus says it has had success in on-orbit testing of water plasma propulsion and other key elements of its Vigoride in-space transportation vehicle, SpaceNews reports. Since July, the company has been firing the water plasma thruster and performing in-space maneuvers on a 16-unit Cubesat.

Early results are promising … "This successfully demonstrates for the first time in-space water plasma propulsion, and also demonstrates the technology, which has the highest specific impulse among other water-based propulsion," the company said. One promising application for the technology is moving satellites from the orbit where they are dropped off by large rockets conducting rideshare missions to their optimal orbital locations. On-orbit testing will continue.

Soyuz FG makes final ride into space. The venerable Soyuz FG rocket launched for the 70th time on Wednesday, lofting Oleg Skripochka (Russia), Jessica Meir (United States), and Hazzaa Al Mansouri (United Arab Emirates) to the International Space Station. The Soyuz FG variant served as a bridge between the older Soyuz-U and the newer Soyuz 2 rocket variants, reports. The FG launched for the first time in May 2001.

Served NASA and the Russians well … The Soyuz FG has been the only Russian rocket to launch humans to the International Space Station for the last 17 years, and since the retirement of the US Space Shuttle fleet in July 2011, it has been the only rocket capable of transporting people to the International Space Station. The rocket's only failure came in 2018, when the crew had to make an emergency landing.

Japanese rocket safely launches after pad issue. A Japanese H-2B rocket flew into orbit Tuesday from the Tanegashima Space Center, Spaceflight Now reports. The automated cargo freighter was loaded with 4.1 tons of batteries, experiments, spacewalk equipment, water, and provisions for the International Space Station.

Surviving a fire … The launch followed a first attempt September 10, when a dramatic fire on the launchpad halted the countdown. Officials determined the fire was likely caused by static electricity and high concentrations of oxygen that dripped from the rocket's main engines during the September 10 countdown. After instituting unspecific "corrective actions," Mitsubishi Heavy Industries returned the H-2B rocket to the launchpad a half-day before Tuesday's launch to begin a new countdown.
