The only passenger is a life-size test dummy, named Ripley from the Alien movies.
If the rest of the SpaceX mission goes as planned, two astronauts, Bob Behnken and Doug Hurley, could be flying aboard the Crew Dragon as early as July, NPR's Nell Greenfieldboyce reported.
NASA TV is the U.S. space agency's around-the-clock educational broadcast, which streams NASA rocket launches among other segments. NASA selected SpaceX and Boeing to design and build crew-carrying spacecraft to shepherd astronauts to and from the space station - replacements for the Space Shuttle, which NASA retired in 2011. It will not be tested until April, in a mission similar to SpaceX's.
Global surge in measles poses serious threat to children
The severity of measles varies from case to case, says Robert Murphy, MD, professor of medicine at Northwestern University. This is despite there being a vaccine for measles readily available in most countries, which is cheap and effective.
A SpaceX rocket with an unmanned crew capsule blasted off on Saturday for the International Space Station, in a key milestone for Elon Musk's space company and NASA's long-delayed goal to resume human spaceflight from USA soil later this year.
William Gerstenmaier, the associate administrator for Human Exploration and Operations at NASA, said at a news conference last week that the launch "is an absolutely critical first step". Even though no one will be riding this rocket, Elon Musk's company has everything riding on the success of this mission.
NASA is anxious for reliable transit to and from the space station.
The Crew Dragon features solar arrays affixed to the side of the spacecraft's trunk, a launch escape system that will allow crew members to escape an anomaly at any point during flight, a large hatch and windows and a redesigned outer mold line to enhance crew comfort.
Pakistan and India step back from the brink, but unease continues
Pakistan's army said in a statement Saturday that the soldiers were killed in the Nakiyal region of Kashmir in the past 24 hours. His return is expected to avert a unsafe confrontation that had raised fears of a wider conflict between the two countries.
SpaceX's Crew Dragon - the first crew-capable spacecraft the company has ever produced - is about to be tested in a big way.
In 2008, the agency first awarded $1.6 billion to Hawthorne-based SpaceX for 12 resupply flights and $1.9 billion for eight flights to Orbital ATK, which was acquired by Northrop Grumman Corp. past year. Those precautions include additional thrusters in case they need to abort after launch but before reaching orbit, and an extra parachute (four instead of the usual three) for landing.
NASA's embrace of commercial firms for closer-to-home missions is indicative of what's happened in other industries, analysts said.
Dragon will dock in the ISS 27 hours after launching where it will spend five days before re-entering Earth's atmosphere and splashing into the Atlantic ocean off the coast of Florida.
UNSC blacklists Osama bin Laden's son, seen as successor of Al Qaida
His father was killed during a USA military raid in May 2011 on the secret complex where he had been living in Abbottabad, Pakistan.
A live stream of the launch will be available on both NASA's and SpaceX's YouTube channels. Hurley will ride the Dragon and Ferguson the Starliner.
