NASA’s Orion spacecraft that flew into space in 2014 has completed its trek from the agency’s Kennedy Space Center in Florida to the Littleton, Colorado, facility of Orion prime contractor Lockheed Martin. Engineers will perform final decontamination of the crew module, continue post-flight analysis and evaluate a new acoustic technology to determine if the method can produce enough energy to simulate the acoustic loads Orion will experience during launch and ascent atop NASA’s Space Launch System rocket. Check out images of Orion and read more about the acoustic testing here.
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.
As NASA’s Orion Program continues developing and building the spacecraft that will fly to space atop the agency’s Space Launch System rocket to new destinations in the solar system, we’re sharing our progress on Orion’s Flickr site.
There we have photos of recent visits by Orion Program managers to companies around the country which are building critical pieces of the spacecraft, engineers getting essential hardware elements ready for testing, images of the Orion that flew in space in 2014 and many of the people who have contributed their expertise, energy and time to develop, build and fly the spacecraft that will help push the boundaries of human space exploration.

Orion’s crew module adapter (CMA) simulator arrived at NASA Glenn’s Plum Brook Station in Sandusky, Ohio on June 22. The simulator was built at the agency’s Kennedy Space Center in Florida and moved to Plum Brook for Orion service module testing scheduled to begin later this year. At Plum Brook’s Space Power Facility, the CMA and the service module provided by ESA (European Space Agency) will be integrated and then undergo acoustics and mechanical vibration tests that simulate the noise and shaking the service module will endure when the spacecraft heads to space atop the Space Launch System rocket. The service module is a critical part of Orion and houses all the air, nitrogen and water for crews, in-space propulsion, and batteries and solar arrays to generate power.
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 recently celebrated the 50th anniversary of the first American spacewalk on June 3, 1965. On that day, supported by a mission control team in Houston, Ed White (shown above) exited his spacecraft during the Gemini 4 mission and spent more than 20 minutes in the void of space. Since this historic first, NASA astronauts have performed spacewalks, or extravehicular activity (EVA) in NASA-speak, on the Gemini, Apollo, Skylab, Space Shuttle and International Space Station programs. Astronauts have explored the lunar surface, completed 82 spacewalks outside of the space shuttle, and 187 spacewalks, to date, outside the International Space Station. A total of 166 hours of spacewalks were carried out to service the Hubble Space Telescope. Today, NASA is developing new advanced spacesuits for use by astronauts as they travel to new deep-space destinations on the journey to Mars.
Engineers and technicians at NASA’s Johnson Space Center in Houston continue to test the spacesuit astronauts will wear in the agency’s Orion spacecraft on trips to deep space. The Modified Advanced Crew Escape Suit is a closed-loop version of the launch and entry suits worn by space shuttle astronauts. In addition, a next-generation suit will incorporate a number of technology advances to shorten preparation time, improve safety and boost astronaut capabilities during spacewalks and surface activities.
Check out this video on the legacy of 50 years of spacewalk activities that paved the way for future missions.
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. Check out more, including a timelapse video of the assembly here.
The construction of an Orion crew module and crew module adapter full-scale mockup has been completed at the Littleton, Colorado facility of Lockheed Martin, NASA’s prime contractor for Orion. This mockup was transferred to the company’s Orion Test Lab on May 13, where engineers will configure it with the exact harnessing, electrical power, sensors, avionics and flight software needed to support Exploration Mission-1 (EM-1), the first flight of Orion atop NASA’s Space Launch System rocket. Orion’s team of engineers will use the mockup to verify the configuration of these vehicle components for EM-1, which ultimately saves assembly time and reduces risk. The mockup will then be connected to hardware emulations of the full EM-1 stack (Orion crew module, European Service Module, second stage booster and the Space Launch System) as well as ground support equipment. Once it’s connected, the team will simulate and test every aspect of the EM-1 mission from launch to splashdown. Orion will enable astronauts to explore new destinations in the solar system, including an asteroid and on toward Mars.
