Somewhat amusing that Boeing has told the assembled media if this test doesn't go to plan, they aren't allowed to publish anything!

They really can't get their media message right at all.

And Boeing says it wasn't really them, but a miscommunication relating to the 45th, so fair enough.

#Starliner’s integrated propulsion system hot fire test was a success. This paves the way for both the capsule’s pad abort test and upcoming flights to @Space_Station later this year.

Thank you, @NASA and the NASA White Sands Test Facility, for your help in making this qualification test a success. Thank you to our #Starliner team who showed their resiliency while working through development challenges.

Attaching the photo from the tweet. Shows an interesting configuration with three down thrusters, one side thruster and two up thrusters. The down and side thrusters are firing.

WASHINGTON — Boeing has completed ground testing of the thrusters for its CST-100 Starliner commercial crew vehicle, nearly a year after a setback in earlier testing of those thrusters.

In a statement, Boeing said it completed hot-fire testing May 23 of the spacecraft’s entire propulsion system, including various thrusters, fuel tanks and related systems within a “flight-like” service module of the spacecraft. Those tests took place at NASA’s White Sands Test Facility in New Mexico.

A series of tests demonstrated thruster firings for in-space maneuvers, high-altitude aborts and low-altitude aborts. The company said the tests were all successful.

Boeing Completes Starliner Hot Fire Test

Boeing teams ran multiple tests on Starliner’s in-space maneuvering system and the spacecraft’s launch abort system on Thursday at NASA’s White Sands Test Facility in New Mexico. Photo credit: Boeing

Boeing’s CST-100 Starliner propulsion system was put to the test on Thursday at NASA’s White Sands Test Facility in New Mexico in support of NASA’s Commercial Crew Program. Teams ran multiple tests on Starliner’s in-space maneuvering system and the spacecraft’s launch abort system, which are key elements on the path to restore America’s capability to fly astronauts to the International Space Station on American rockets and spacecraft from U.S. soil.

The test used a flight-like Starliner service module with a full propulsion system comprising of fuel and helium tanks, reaction control system and orbital maneuvering and attitude control thrusters, launch abort engines and all necessary fuel lines and avionics.

During the test:

    19 thrusters fired to simulate in-space maneuvers.
    12 thrusters fired to simulate a high-altitude abort.
    22 propulsion elements, including the launch abort engines, fired to simulate a low-altitude abort.

Boeing’s Starliner will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida. The company will complete a Starliner pad abort test and uncrewed flight test, called Orbital Flight Test, to the station ahead of the first flight test with a crew onboard. As commercial crew providers, Boeing and SpaceX, begin to make regular flights to the space station, NASA will continue to advance its mission to go beyond low-Earth orbit and establish a human presence on the Moon with the ultimate goal of sending astronauts to Mars.

Typically written up in L2 first for articles and such.

Nice video showing Starliner's SM underside with the larger-size engines, as well as the RCS pods. Annoying PR superimposed after a few seconds, but you can get a good brief look at the test before that.

What's the official technical name for these engines?

The abort engines are a derivative of the RS-88, but I'm not sure what their official name is.

The official name of the starliner version is just Launch Abort Engine (LAE). Original RS-88 version ran on ethalox and LAE is hypergolic. Detailed RS-88 version designations are not public.
