Herman Melville, in Moby Dick, spoke for wanderers in all epochs and meridians: "I am tormented with an everlasting itch for things remote. I love to sail forbidden seas..."
Nasa launched Orion test flight for the zeitgeist of Mars voyage on Dec, 5 2014.This is for the first time a spacecraft built for humans will travel out of low earth orbit (LEO) till 2021. Before that Nasa will again launch test flights in 2017 and 2018. The Orion space capsule was launched from a pad at Cape Canaveral Air Force Station at 7:05 a.m. EST (1205 GMT).The prototype spacecraft embarked on a series of tests in orbit before its planned splashdown in the Pacific Ocean at about 11:30 a.m. EST (1630 GMT), 4.5 hours after leaving the planet.Approximately 1,200 sensors aboard Orion to monitor the way the capsule's computers and other technology behave in the harsh space environment. Orion flew through belts of radiation twice during the flight (once on the way out, and again on the way back to Earth), allowing scientists to see how the spacecraft's computers behave in a high-radiation environment.
Scientists and engineers want to test how key systems on Orion work during this test. Eventually, NASA officials hope that modified versions of Orion will take humans to deep-space destinations like an asteroid, and even Mars. Engineers working with the computers onboard Orion hope to see how the instruments behave when they're exposed to high amounts of radiation outside Earth's protective atmosphere.
"We do have radiation sensors on board, for example, so we're actually measuring different parts of the vehicle for what we're seeing, what the environment is inside," said Mark Geyer, Orion program manager. "We have 1,200 sensors, and a lot of those are loads, so they measure the impact loads when we land [and during] ascent. We'll get acoustic data inside and out, so we know how loud it is — those kinds of things. A lot of that is for the vehicle, but it's also to understand what the environment for the crew is going to be."
