nasa test fires rocket engine with 3d-printed \'shock absorber\' for deep space missions

NASA tested its powerful RS-
On 2018, the 25 engine introduced an unconventional new part for the first time this week.
This complex machine has more than 7,500 parts, but one important part is made with a 3D printer.
The engine test lasted a little more than 6 minutes, and on Tuesday at NASA\'s Stanis Space Center, a huge water vapor plume was emitted in the cold Mississippi sky.
Engineers at Air jet rocket thrust say this is the second time they have tested 3D-
Printed pogo accumulator, \"printed\" using laser and metal powder at a factory in Canoga Park, California\"
Compared to manual construction, the machine divided the parts into two halves for construction in a few weeks, which could take years, according to Alan von, one of the project\'s chief mechanical design engineers.
He said that this part is a \"shock absorber\" that will make it easier for astronauts to fly into space.
\"When you\'re traveling along the cobblestone road, you have a bumper in your car, which makes it go well, and that\'s what the astronauts are doing,\" Feng said . \", Stand in front of the giant engine at the Rocketdyne plant in Mississippi.
John Young smuggled a corn.
\"When astronauts get into space, they feel this vibration, just like jumping on a pogo stick.
This is the source of the name.
\"While the astronauts felt this, it caused a lot of problems with the engine, so we don\'t want that to happen,\" he said . \".
Over the next year, engineers plan to add nearly 40 additional 3-
Printing parts to RS-25 engine.
NASA has begun increasing testing at rocket testing facilities in Magnolia State.
\"The series we\'re doing nowincludes]
New hardware to be developed ,[tested]
And pass the certification, \"RS-Ronnie Rigny
Said 25 test project managers at Stanis space center.
\"Once the designs are accepted, they will be manufactured regularly for the engines that will be built on this project in the future.
Riggny noted that a flight controller was also tested on Tuesday to help the engine communicate with the entire rocket.
The plan aims to reduce the waste and cost of space launch systems (SLS)
This is NASA\'s next generation of rockets and heavy rockets. lift vehicle. Four RS-
The 25 engines and two solid rocket boosters will push huge spaceships beyond the Earth\'s atmosphere.
The SLS program will also use the re-used RS-
25 engines of the space shuttle era.
Unlike the space shuttle, the SLS rocket is consumable.
\"When we choose RS-
For the SLS project, we avoided huge costs ahead of time, \"said Steve woford, manager of the Steve liquid engine project. “For new RS-
25 engines. we are now starting to restart a program.
Design these engines to make them 30% more affordable.
\"NASA claims that SLS will be the most powerful rocket ever built by humans, and by the 1930s s it may send humans to the surface of Mars, but the price may be too high.
Experts estimate that the cost of a trip to Mars ranges from $100 billion to $1 trillion.
NASA\'s deputy director of human exploration, William G Stanmeyer, has previously said the space agency may not have funds to send humans to the red planet.
He also said that the lack of air on Mars is an obstacle for manned spacecraft to land on the surface of Mars because air helps slow down the decline of the spacecraft.
\"NASA is doing strategic work this year --to-
Planning the annual budget process for future needs, including deep space missions to the moon, Mars and elsewhere, and taking on our challenging work within existing funding, \"Cheryl Warner, a nasa spokesman said in a statement from Fox News.
\"We are currently waiting for more information on the budget for the fiscal year 2019, which we expect to receive next month.
NASA plans to test four RS-
At the beginning of 2019, 25 engines were used.
