NASA conducted a new test of a flight controller installed on the Aerojet Rocketdyne developmental RS-25 rocket engine No. 0525. The 319 seconds hotfire test was conducted on the A-1 Test Stand at the John C. Stennis Space Center in Mississippi, on 14 August 2018, at 19:41 UTC (14:41 CDT, 15:41 EDT). NASA's Space Launch System (SLS), the most powerful rocket ever built, will be powered by four RS-25 engines firing simultaneously.

WASHINGTON — NASA says an Aug. 14 test of an engine for the Space Launch System was a success despite an unspecified "facility issue" that caused the test to end early.

The test of the RS-25 engine on the A-1 stand at the Stennis Space Center in Mississippi was the first in a new series of static-fire tests of the shuttle-era engine that will be used in the core stage of the SLS. The engine, a developmental unit designated No. 0525, tested a flight controller unit that will be used on flight models of the engine as well as new manufacturing techniques intended to reduce the cost of future engines.

NASA Stennis announced prior to the test that the test would run for eight minutes and 20 seconds. However, in a tweet after the test, Stennis said the test ended after five minutes and 19 seconds.

An Aug. 15 statement fr om Stennis about the test made no mention of the planned or actual duration of the test. "All test objectives were met during the hot fire," the center's statement noted.

Stennis spokesperson Valerie Buckingham confirmed Aug. 15 that the test was cut short. "The test ended early due to a facility issue, but all test objectives were met," she said in an emailed response to a SpaceNews inquiry. She later said she didn't know the details about the problem, other than it did not damage the engine itself.

Aerojet Rocketdyne, which manufactures the RS-25, also said the test ended early because of a facility problem, but deferred questions on the issue to NASA Stennis. The company said in a statement that the engine performed as expected.

Among the objectives of the test was to test a new manufacturing approach called hot isostatic pressing for the engine's main combustion chamber that the company says "saves considerable time and money" over conventional techniques. "Initial test data indicates the chamber performed flawlessly during the 319-second test," Aerojet Rocketdyne said.

That technique is being evaluated for use on future versions of the RS-25. The first four SLS missions will use existing engines, originally manufactured for the space shuttle and updated for SLS. Later SLS launches will require new RS-25 engines.

"As we develop a new generation of RS-25 engines, ensuring they continue to remain reliable while reducing costs is a major focus at Aerojet Rocketdyne," said Eileen Drake, chief executive and president of the company. "That's why we're working hard to drive down costs on the RS-25 by incorporating the most modern and efficient manufacturing techniques."

NASA is planning eight more tests using the same developmental RS-25 engine that will go through early 2019. Later in 2019, another test stand at Stennis will host a "green run" static-fire test of the first SLS core stage, where its four RS-25 engines will fire simultaneously.

Among those attending the test was NASA Administrator Jim Bridenstine, making his first visit to Stennis since becoming administrator. The visit was part of a series of appearances at NASA facilities in the region that included the Michoud Assembly Facility in New Orleans Aug. 13 and the Marshall Space Flight Center in Huntsville, Alabama, Aug. 15.

In a webcast of the launch, Bridenstine didn't appear to be aware that the test had been cut short. "I've seen a lot of launches as a member of Congress before and now as NASA administrator, but the rockets always leave," he said. "In this particular case, the rocket stayed, and it stayed for 500 seconds of just a heart-pounding thrust."

He reiterated the importance of the SLS in carrying out human missions to the moon and beyond despite the vehicle's years of delays. "This is our opportunity to follow through on the president's Space Policy Directive 1, which says that we're going to the moon," he said, saying the SLS fits into a "sustainable" architecture wh ere "we want every piece of this architecture to ultimately be reusable." The SLS is currently an expendable vehicle, including the original shuttle-era RS-25 engines that were designed for reuse.

China completes 1st test on propulsion system for space experiment module
XI'AN, Aug. 17 (Xinhua) -- Chinese researchers have successfully completed the first test of the propulsion system for the experiment module of the country's planned space station.
The test consisted of eight procedures that covered all working conditions of an in-orbit experiment module. It also simulated possible errors the module may encounter in space, according to a research institute affiliated with China Aerospace Science and Technology Corporation (CASC).
The test proved that the design of the propulsion system was scientific and its parameters setting was correct, according to the institute.
Two experiment modules of China's planned space station will be sent into space in 2021 and 2022, according to Yang Liwei, director of the China Manned Space Engineering Office and the country's first astronaut.
China is accelerating its timetable for a space station, with the core capsule expected to be launched in 2020, said Yang.

China tests propulsion system of space station's lab capsules
BEIJING, Aug. 18 (Xinhua) -- Engineers have successfully tested the propulsion system of China's planned space station lab capsules, a key step in its space station program.
Weighing 66 tonnes, the space station will comprise a core module and two lab capsules. The propulsion system will determine whether lab capsules can move in space.
Engineers designed 36 engines for the propulsion system with four to adjust the capsules' operation orbit and 32 to adjust flight attitude. Each engine is designed to work for at least 15 years, according to the China Aerospace Science and Technology Corporation (CASC), the main manufacturer of the space station.
The engines worked well and passed tests in Shanghai, said the CASC.
China is accelerating its timetable for the Tiangong space station, with the Tianhe core capsule expected to be launched in 2020. The station is due for completion around 2022.

GLSV-F11's cryogenic engine tested
TNN | Aug 31, 2018, 06:17 IST

BENGALURU: Indian Space Research Organisation (Isro) on Thursday said it has successfully completed the hot test of cryogenic engine for the GSLV-F11, which is scheduled to launch GSAT-7A in November this year.

A hot test is a ground test to check the safety and efficiency of the engine. It was conducted on Monday at Isro Propulsion Complex in Mahendragiri for 200 seconds during which the engine operated in the nominal and 13% uprated thrust regimes.

"All the propulsion parameters were found to be satisfactory. For the first time, indigenously developed copper alloy was used in the engine," an Isro spokesman said.

The cryogenic engine will now be integrated with the propellant tanks, stage structures and associated fluid lines to realise the fully integrated flight cryogenic stage.
