The powerhouse that will help NASA's Orion spacecraft venture beyond the Moon is stateside. The European-built service module that will propel, power and cool during Orion flight to the Moon on Exploration Mission-1 arrived from Germany at the agency's Kennedy Space Center in Florida on Tuesday to begin final outfitting, integration and testing with the crew module and other Orion elements.

The service module is integral to human missions to the Moon and Mars. After Orion launches on top of the agency's Space Launch System rocket, the service module will be responsible for in-space maneuvering throughout the mission, including course corrections. The service module will also provide the powerful burns to insert Orion into lunar orbit and again to get out of lunar orbit and return to Earth.

It is provided by ESA (European Space Agency) and built by ESA's prime contractor Airbus of Bremen, Germany. NASA's prime contractor for Orion, Lockheed Martin, built the crew module and other elements of the spacecraft.

"We have a strong foundation of cooperation with ESA through the International Space Station partnership, and the arrival of the service module signifies that our international collaboration extends to our deep space human exploration efforts as well," said Bill Gerstenmaier, NASA's associate administrator for Human Exploration and Operations.

The European-built service module brings together new technology and lightweight materials while taking advantage of spaceflight-proven hardware. It is comprised of more than 20,000 components, including four solar array wings that provide enough electricity to power two three-bedroom homes, as well as an orbital maneuvering system engine, a recently refurbished engine previously used for in-orbit control by the space shuttle.

Beginning with Exploration Mission-2, the module also will provide air and water for astronauts flying inside Orion, which will carry people to destinations farther than anyone has travelled before and return them safely to Earth.

"Our teams have worked together incredibly hard to develop a service module that will make missions to the Moon and beyond a reality," said Mark Kirasich, NASA's Orion program manager. "It is quite an accomplishment of ESA and Airbus to have completed the developmental work on the module and have this major delivery milestone behind us."

Now that the service module is at Kennedy, it will undergo a host of tests and integration work ahead of Exploration Mission-1. Engineers will complete functional checkouts to ensure all elements are working properly before it is connected to the Orion crew module. Teams will weld together fluid lines to route gases and fuel and make electrical wiring connections.

The service module and crew module will be mated, and the combined spacecraft will be sent to NASA's Glenn Research Center's Plum Brook Station in Ohio early next year where it will undergo 60 days of continuous testing in the world's largest thermal vacuum chamber to ensure Orion can withstand the harsh environment of deep space. Once that testing is complete, it will return to Kennedy for integration with the SLS rocket in preparation for launch.

NASA is leading the next steps to establish a permanent human presence at the Moon. The first in a series of increasingly complex missions, Exploration Mission-1 is a flight test of an uncrewed Orion spacecraft and SLS rocket that will launch from NASA's modernized spaceport at Kennedy.

The mission will send Orion 40,000 miles beyond the Moon and back and pave the road for future missions with astronauts. Together, NASA and its partners will build the infrastructure needed to explore the Moon for decades to come while laying the groundwork for future missions to Mars.

First moon walk's commemorative plaque sold for $468,500
New York (AFP) Nov 4, 2018
A commemorative plaque brought to the moon on the Apollo 11 mission went under the hammer for $468,500 in Texas, as part of a huge collection that once belonged to late astronaut Neil Armstrong, auctioneers said. The plaque includes a representation of the lunar module that touched down on the moon on July 20, 1969. Once back on Earth, it was mounted on a wooden base before being offered to Armstrong, the first man to set foot on the Moon. The other two astronauts who took part in the missio ... read more
