Tune into The Weather Channel beginning at 6:30 a.m. ET for live coverage of the Orion launch.

Weather conditions will be favorable for NASA's Orion spacecraft launch tomorrow morning.

The spacecraft, designed to eventually carry astronauts to Mars,is scheduled to lift off on its first test flight at 7:05 a.m. ET Thursday from Cape Canaveral, Florida. The launch window will be open for two hours and 39 minutes.

Weather.com senior meteorologist Jonathan Erdman said that temperatures during the launch window are forecast to be in the upper 60s with a northeast breeze around 10 mph.Skies are expected to be partly cloudy and there's a "very small" (less than 10 percent) chance for showers.

As NBC reports, the Orion test launch is the first launch of a spacecraft designed to carry humans outside of orbit since Project Apollo.

"Going from where we're at today with the space station to distances like Mars is extremely challenging," Jason Crusan, director of advanced exploration systems at NASA, told Space.com.

"With this week's flight of Orion, we're now entering into the next phase of advancing our capabilities, into what we call our 'proving ground' activities."

NASA says the unmanned capsule will travel 3,600 miles from Earth and orbit the planet twice. It will re-enter Earth's atmosphere at 20,000 mph, withstanding heat as high as 4,000 degrees, before splashing down in the Pacific Ocean about 600 miles off the coast of Baja California. Two U.S. Navy ships, the USS Anchorage and the USNS Salvor, will help NASA recover the capsule.

This first flight won't carry astronauts, but moves NASA closer to getting back in the manned spaceflight business. Since the space shuttle program ended in 2011, the U.S. has paid Russia's space agency to launch astronauts to the International Space Station.

If all goes well, the test flight will set the stage for the next Orion test, EM-1, that will send a spacecraft to the moon and back by 2018. After EM-1 comes EM-2, the first planned manned launch for the Orion spacecraft with a target date of 2021.

Just where those astronauts will go is still undetermined, NBC News reports. There were suggestions that EM-2 could send astronauts to an asteroid, but a NASA official said that it was still too "premature" to make plans for any manned destination.

NASA might be hesitant to commit to any solid plans because the rocket designed to launch EM-1 and EM-2 into space is still under development. Once completed, the rocket, known as NASA's Space Launch System, will likely become the world's most powerful rocket.
