Teams with NASA’s Kennedy Space Center Exploration Ground Systems and primary contractor, Jacobs, are fueling the Orion service module ahead of the Artemis I mission. The spacecraft currently resides in Kennedy’s Multi-Payload Processing Facility alongside the Interim Cryogenic Propulsion System (ICPS), the rocket’s upper stage that will send Orion to the Moon. After servicing, these elements will be integrated with the flight components of the Space Launch System, which are being assembled in the Vehicle Assembly Building.
Technicians began loading Orion’s service module with oxidizer, which will power the Orbital Maneuvering System main engine and auxiliary thrusters on the European-built service module ahead of propellant loading. These auxiliary thrusters stabilize and control the rotation of the spacecraft after it separates from the ICPS. Once the service module is loaded, teams will fuel the crew module to support thermal control of the internal avionics and the reaction control system. These 12 thrusters steady the crew module and control its rotation after separation from the service module.
Once Orion servicing is complete, teams will fill the ICPS. This liquid oxygen/liquid hydrogen-based system will push the spacecraft beyond the Moon for the test flight under the agency’s Artemis program. In several weeks, when fueling is complete, Orion will move to the center’s Launch Abort System Facility to integrate its launch abort system, and the ICPS will move to the Vehicle Assembly Building to be stacked atop the mobile launcher.
NASA’s Artemis IOrion spacecraft is being outfitted with additional artwork as technicians began installing the logo for ESA (European Space Agency). ESA provided the European-built service module, which provides power and propulsion for the Orion spacecraft, and will also provide water and air for astronauts on future missions.
Artemis I extends NASA and ESA’s strong international partnership beyond low-Earth orbit to lunar exploration with Orion on Artemis missions. The ESA logo joins the historic NASA “meatball” insignia on the Artemis I spacecraft adapter jettison fairing panels that protect the service module during launch.
Orion is currently stationed at NASA’s Kennedy Space Center in the Multi-Payload Processing Facility, where it will undergo fueling and servicing by NASA’s Exploration Ground Systems and Jacobs Technology teams in preparation for the upcoming flight test with the Space Launch System rocket under the agency’s Artemis program.
Mars enthusiasts around the world can participate in NASA’s journey to Mars by adding their names to a silicon microchip headed to the Red Planet aboard NASA’s InSight Mars lander, scheduled to launch next year.
The fly-your-name opportunity comes with “frequent flier” points to reflect an individual’s personal participation in NASA’s journey to Mars, which will span multiple missions and multiple decades. The InSight mission offers the second such opportunity for space exploration fans to collect points by flying their names aboard a NASA mission, with more opportunities to follow.
Last December, the names of 1.38 million people flew on a chip aboard the first flight of NASA’s Orion spacecraft, which will carry astronauts to deep space destinations including Mars and an asteroid. After InSight, the next opportunity to earn frequent flier points will be NASA’s Exploration Mission-1, the first planned test flight bringing together the Space Launch System rocket and Orion capsule in preparation for human missions to Mars and beyond.
Submissions will be accepted until Sept. 8. To send your name to Mars aboard InSight, go to: http://go.usa.gov/3Aj3G
On Thursday, Aug. 13, NASA engineers fired up a Space Launch System RS-25 rocket engine at the agency’s Stennis Space Center near Bay St. Louis, Mississippi, in the latest test to collect performance data that will be used to ready the engines for missions to deep space. Orion and the astronauts it carries will fly atop the Space Launch System on missions to an asteroid and eventually on the journey to Mars.
Engineers at NASA’s Plum Brook Station in Sandusky, Ohio, began the first of a series of modal tests on a structural representation of the crew module adapter (CMA) for Orion. The CMA will connect the capsule to the ESA (European Space Agency)-provided service module for the spacecraft’s next mission, Exploration Mission-1. The service module is designed to be the powerhouse that fuels and propels Orion in space.
The tests at Plum Brook Station shake structural elements at various frequencies to simulate how launch vibrations and acoustics will affect the spacecraft during its trip to space atop NASA’s Space Launch System rocket. They are being conducted ahead of the arrival of a structural representation of the ESA service module to the facility this fall for additional testing.
Engineers are using a “building block” approach to testing in which they evaluate each piece as the elements composing the service module are stacked atop each other to validate it before flight hardware begins arriving in 2017.
This week, engineers completed the second experimental test flight of NASA’s Low-Density Supersonic Decelerator (LDSD). During the flight, which took place June 8, the team tested two decelerator technologies that could enable larger payloads to land safely on the surface of Mars, and allow access to more of the planet’s surface by assisting landings at higher-altitude sites. The technology is critical to enabling our journey to Mars. Read about the test here.
Meanwhile, NASA completed another test June 11 of the RS-25 engine that will power the Space Launch System (SLS) rocket with Orion atop it to space. This is the third firing of an RS-25 development engine on the A-1 test stand at the agency’s Stennis Space Center near Bay St. Louis, Mississippi. Four more test are planned for the current development engine.
New video animation also was released this week showing SLS launching Orion to deep space destinations. Check out the smoke and fire!
NASA’s Space Launch System (SLS), which will launch Orion on missions to deep space destinations like an asteroid and on toward Mars marked important steps this week to prepare for journeys beyond Earth orbit.
Engineers at the agency’s Stennis Space Center near Bay St. Louis, Mississippi, conducted a successful 450-second test of the RS-25 rocket engine May 28. The hotfire test was conducted on the historic A-1 Test Stand where Apollo Program rocket stages and Space Shuttle Program main engines also were tested. RS-25 engines tested on the stand will power the core stage of NASA’s new rocket with Orion atop it.
One of the objectives being evaluated in this test is the new engine controller, or “brain.” The RS-25 is unique among many engines in that it automatically runs through its cycles and programs. The controller monitors the engine conditions and communicates the performance needs. The performance specifications, such as what percentage of thrust is needed and when, are programmed into the controller before the engines are fired. For example, if the engine is required to cycle up to 90 percent thrust, the controller monitors the fuel mixture ratio and regulates the thrust accordingly. It is essential that the controller communicates clearly with the engine; the SLS will be bigger than previous rockets and fly unprecedented missions, and its engines will have to perform in new ways.
Engine maker Aerojet Rocketdyne also completed RS-25 Engine 2063 at Stennis, after approximately three months of work. The new engine becomes the 16th assembled RS-25 flight engine in inventory for SLS flights. The engine will be one of four RS-25s used to power Exploration Mission 2, the second SLS launch with Orion targeted for the 2021 time frame. Testing of these four engines will begin later this year as work accelerates on NASA’s newest launch vehicle. Four previously-flown RS-25s will be attached to the first SLS core stage and test fired together as a stage before being approved for the first SLS launch planned for 2018, the first integrated mission with Orion.
