NASA Conducts SLS Rocket Core Stage Test for Artemis I Moon Mission

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA conducted a hot fire Saturday of the core stage for the agency’s Space Launch System (SLS) rocket that will launch the Artemis I mission to the Moon. The hot fire is the final test of the Green Run series.

The test plan called for the rocket’s four RS-25 engines to fire for a little more than eight minutes – the same amount of time it will take to send the rocket to space following launch. The team successfully completed the countdown and ignited the engines, but the engines shut down a little more than one minute into the hot fire.

The core stage for the first flight of NASA’s Space Launch System rocket is seen in the B-2 Test Stand during a hot fire test Jan. 16, 2021, at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. (NASA Television)

NASA prepares Space Launch System rocket for Artemis I Launch

 

NASA - National Aeronautics and Space AdministrationFlorida – NASA has stacked the first piece of the Space Launch System (SLS) rocket on the mobile launcher in preparation for the Artemis I launch next year. At NASA’s Kennedy Space Center in Florida, engineers lowered the first of 10 segments into place November 21st, 2020 for the twin solid rocket boosters that will power the first flight of the agency’s new deep space rocket.

Artemis I will be an uncrewed flight to test the SLS rocket and Orion spacecraft as an integrated system ahead of crewed flights to the Moon with the Artemis program.

The solid rocket boosters are the first components of the SLS rocket to be stacked and will help support the remaining rocket pieces and the Orion spacecraft. (NASA/Kim Shiflett)

NASA says Rocket Engines may soon be produced by 3D Printing

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – As part of the Artemis program, NASA is returning astronauts to the Moon where we will prepare for human exploration of Mars. Additive manufacturing, or 3D printing, experts from NASA, industry, and academia are pioneering methods to print the rocket parts that could power those journeys.

NASA’s Rapid Analysis and Manufacturing Propulsion Technology project, or RAMPT, is advancing development of an additive manufacturing technique to 3D print rocket engine parts using metal powder and lasers.

Blown powder directed energy deposition can produce large structures – such as these engine nozzles – cheaper and quicker than traditional fabrication techniques. (NASA)

NASA to test World’s Largest Rocket Fuel Tank

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – Engineers are preparing to push a test article identical to the world’s largest rocket fuel tank beyond its design limits and find its breaking point during upcoming tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Earlier this year, a NASA and Boeing test team subjected a test version of the Space Launch System (SLS) liquid hydrogen tank to a series of 37 tests that simulate liftoff and flight stresses by using large hydraulic pistons to push and pull on the test tank with millions of pounds of force.  

Engineers are preparing to push a test article identical to the world’s largest rocket fuel tank beyond its design limits and find its breaking point during upcoming tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama. This will be the largest-ever controlled test-to-failure of a NASA rocket stage fuel tank. (NASA/MSFC)

NASA reports All Four Engines Are Attached to the SLS Core Stage for Artemis I Mission

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – All four RS-25 engines were structurally mated to the core stage for NASA’s Space Launch System (SLS) rocket for Artemis I, the first mission of SLS and NASA’s Orion spacecraft. To complete assembly of the rocket stage, engineers and technicians are now integrating the propulsion and electrical systems within the structure.

The completed core stage with all four RS-25 engines attached is the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program that first sent Americans to the Moon.

A Look Back at NASA’s efforts to send Astronauts into Deep Space from 2017

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Below are the top images from 2017 that tell the story of building and testing the systems that will send astronauts to deep space destinations including the Moon, Mars and beyond.

Construction Completed for Stand to Test SLS’s Largest Fuel Tank

Major construction is complete on NASA’s structural test stand that will ensure SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent. Together, the SLS liquid hydrogen and liquid oxygen tanks will feed 733,000 gallons (nearly 3 million liters) of super-cooled propellant to four RS-25 engines, producing a total of 2 million pounds of thrust at the base of the core stage.

The 215-foot-tall structural test stand for NASA's Space Launch System is seen Sunday, Sept. 24, 2017, at NASA's Marshall Space Flight Center in Huntsville, Alabama. (NASA/Bill Ingalls)

NASA Completes Review of First SLS, Orion Deep Space Exploration Mission

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA is providing an update on the first integrated launch of the Space Launch System (SLS) rocket and Orion spacecraft after completing a comprehensive review of the launch schedule.
 
This uncrewed mission, known as Exploration Mission-1 (EM-1) is a critical flight test for the agency’s human deep space exploration goals. EM-1 lays the foundation for the first crewed flight of SLS and Orion, as well as a regular cadence of missions thereafter near the Moon and beyond.

NASA advances Exploration Objectives in 2016

 

Written by Bob Jacobs / Allard Beutel
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In 2016, NASA drove advances in technology, science, aeronautics and space exploration that enhanced the world’s knowledge, innovation, and stewardship of Earth.

“This past year marked record-breaking progress in our exploration objectives,” said NASA Administrator Charles Bolden. “We advanced the capabilities we’ll need to travel farther into the solar system while increasing observations of our home and the universe, learning more about how to continuously live and work in space, and, of course, inspiring the next generation of leaders to take up our Journey to Mars and make their own discoveries.”

NASA Building Space Launch System’s Core Stage Piece by Piece

 

NASA’s Marshall Space Flight Center

NASA - National Aeronautics and Space AdministrationHuntsville, AL – The largest rocket stage in the world is coming together piece by piece at NASA’s Michoud Assembly Facility in New Orleans, LA. Large elements for NASA’s Space Launch System are in production and will be joined together to create the rocket’s 212-foot-tall core stage, the backbone of the SLS rocket.

Why is NASA building the world’s most powerful rocket? Because SLS is ready to support both near-term missions in the proving ground around the moon starting in 2018, while at the same time being capable of carrying the very large hardware like landers, habitats and other supplies and equipment needed to explore Mars and other deep space destinations in the 2030s and beyond.

Engineers just completed welding the liquid hydrogen tank that will provide fuel for the first SLS flight in 2018. The tank measures more than 130 feet tall, comprises almost two-thirds of the core stage and holds 537,000 gallons of liquid hydrogen -- which is cooled to minus 423 degrees Fahrenheit.

NASA Vehicle Assembly Building Prepared for Another 50 Years of Service

 

NASA - National Aeronautics and Space AdministrationNASA’s Kennedy Space Center, FL – Construction of the Vehicle Assembly Building, or VAB, at NASA’s Kennedy Space Center in Florida began a half-century ago this summer.

After serving through the Apollo and Space Shuttle Programs, the mammoth structure now is undergoing renovations to accommodate future launch vehicles and to continue as a major part of America’s efforts to explore space for another 50 years.
