NASA marked a major milestone today on its journey to Mars as the Orion spacecraft completed its first voyage to space, traveling farther than any spacecraft designed for astronauts has been in more than 40 years.
“Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space on our Journey to Mars,” said NASA Administrator Charles Bolden. “The teams did a tremendous job putting Orion through its paces in the real environment it will endure as we push the boundary of human exploration in the coming years.”
Orion blazed into the morning sky at 12:05 UTC, lifting off from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida on a United Launch Alliance Delta IV Heavy rocket.
The Orion crew module splashed down approximately 4.5 hours later in the Pacific Ocean, 965 km (600 miles) southwest of San Diego.
During the uncrewed test, Orion traveled twice through the Van Allen belt where it experienced high periods of radiation, and reached an altitude of 5 790 km (3 600 miles) above Earth. Orion also hit speeds of 32 186 km/h (20 000 mph) and weathered temperatures approaching 2 204 degrees Celsius (4 000 degrees Fahrenheit) as it entered Earth’s atmosphere.
Orion will open the space between Earth and Mars for exploration by astronauts. This proving ground will be invaluable for testing capabilities future human Mars missions will need. The spacecraft was tested in space to allow engineers to collect critical data to evaluate its performance and improve its design.
The flight tested Orion’s heat shield, avionics, parachutes, computers and key spacecraft separation events, exercising many of the systems critical to the safety of astronauts who will travel in Orion.
Astronauts will board Orion for a first crewed flight in 2021. Many of Orion's systems needed for that flight and others were tested with the first uncrewed flight test today.
On future missions, Orion will launch on NASA’s Space Launch System (SLS) heavy-lift rocket currently being developed at the agency’s Marshall Space Flight Center in Huntsville, Alabama. A 70 metric-ton (77 ton) SLS will send Orion to a distant retrograde orbit around the moon on Exploration Mission-1 in the first test of the fully integrated Orion and SLS system.
“We really pushed Orion as much as we could to give us real data that we can use to improve Orion’s design going forward,” said Mark Geyer, Orion Program manager. “In the coming weeks and months we’ll be taking a look at that invaluable information and applying lessons learned to the next Orion spacecraft already in production for the first mission atop the Space Launch System rocket.”
Orion is the first spacecraft built for astronauts destined for deep space since the storied Apollo missions of the 1960s and 70s. It is designed to go farther than humans have ever traveled, well beyond the moon, pushing the boundaries of spaceflight to new heights.
A team of NASA, U.S. Navy and Lockheed Martin personnel aboard the USS Anchorage are in the process of recovering Orion and will return it to U.S. Naval Base San Diego in the coming days. Orion will then be delivered to NASA’s Kennedy Space Center in Florida, where it will be processed. The crew module will be refurbished for use in Ascent Abort-2 in 2018, a test of Orion’s launch abort system.
Lockheed Martin, NASA’s prime contractor for Orion, began manufacturing the Orion crew module in 2011 and delivered it in July 2012 to the Neil Armstrong Operations & Checkout Facility at Kennedy where final assembly, integration and testing were completed. More than 1 000 companies across the country manufactured or contributed elements to Orion.
