NASA Orion Launch Postponed Till Friday

Updated: | Originally published: ;

A series of problems forced NASA to delay a planned launch of its its new Orion spacecraft on Thursday.

The next launch attempt is slated for Friday at 7:05 a.m. ET.

The launch, an early step in NASA’s mission to send people to Mars, was set to begin at 7:05 a.m. ET on Thursday but was delayed multiple times for a variety of reasons, including a boat in the area and valve trouble on the core booster. Thursday’s launch window closed at 9:44 a.m. ET.

The un-crewed Orion is intended to orbit 3,600 miles above Earth before it finally crashes into the Pacific Ocean. It will measure the effects of high radiation zones on the spacecraft, which has a heat shield to withstand massive temperatures when it speeds into the atmosphere at 20,000 mph, before finally hitting the ocean.

There will be more test-runs to come for Orion, a vessel that NASA hopes will ultimately take astronauts into new places–maybe even Mars.

J-2X -- Back in the Saddle Again (NASA, J-2X, SLS, 11/27/12)A J-2X power pack assembly burns brightly during a hot fire test Nov. 27 at NASA's Stennis Space Center in Mississippi. Engineers pulled the assembly from the test stand in September to install additional instrumentation in the fuel turbopump. The test, which ran for 278 seconds, verified the newly installed strain gauges designed to measure the turbine structural strain when the turbopump is spinning at high speeds that vary between 25,000 and 30,000 rotations-per-minute. The J-2X engine -- built by Pratt & Whitney Rocketdyne of Canoga Park, Calif. -- will power the upper stage of NASA's Space Launch System, managed at the Marshall Space Flight Center in Huntsville, Ala. The new heavy-lift rocket system will launch the Orion spacecraft and enable humans to explore new destinations beyond low Earth orbit. Image credit: NASA/SSC

The 16.5 foot diameter, titanium structure-supported heat shield was fabricated by Lockheed Martin in Denver for Orion. Textron Defense Systems, outside Boston, covered the shield’s outer surface with Avcoat™, an ablative material system used on the Apollo spacecraft. The shield will have to withstand temperatures of 4,000 degrees F (2,200 C).
