SpaceX launches Crew Dragon test flight to prove it can fly humans safely

SpaceX launched an unmanned Crew Dragon craft from Florida to the International Space Station early Saturday, a milestone for Elon Musk's goal of enabling humans to live on other planets and a big win for NASA’s gamble of partnering with private industry. Scores of space tourists gathered in Florida to watch the 2:49 a.m. launch of the Falcon 9 rocket, which went off without a hitch. Crew Dragon is en route to a rendezvous with the station on Sunday, while SpaceX landed the rocket's first stage on a drone ship in the ocean.
“I'm a little emotionally exhausted,” Musk said at a NASA news conference. “It was super stressful. But it worked, so far.”

Musk, who founded SpaceX in 2002, also thanked the launch team and noted several additional milestones on the week-long mission, including docking with the orbiting station and then returning the capsule to Earth. "Today's successful launch marks a new chapter in American excellence, getting us closer to once again flying American Astronauts on American rockets from American soil," NASA Administrator Jim Bridenstine said in a tweet. "Congratulations to SpaceX and NASA teams for this major milestone in our nation's history."
Musk’s company has already made several supply runs to the orbiting lab for NASA. But proving that SpaceX can safely fly humans is key to the company’s ambitions for space tourism and creating a human colony on Mars. Though no astronauts were aboard this first demonstration flight, the successful launch is critical in persuading any doubters and paves the way for SpaceX to launch with astronauts as soon as this summer.
“Human spaceflight is a core value of our business,” Hans Koenigsmann, vice president of build and flight reliability for SpaceX, said at a pre-launch press briefing with NASA Thursday. “We’ve been working on this for close to 17 years. I’m actually humbled at being at this point.”
In 2014, NASA awarded SpaceX and rival Boeing Co. combined contracts worth up to $6.8 billion to fly US astronauts to the space station. The agency chose two companies for the unique public-private partnership to assure safe, reliable and cost-effective access to space while avoiding the perils of one provider having a monopoly. The US government is also eager to have the ability to fly to the ISS without buying seats on Russian Soyuz capsules.Early Saturday, NASA’s Twitter feed and blog posts were filled with images of SpaceX’s Falcon 9 rocket carrying Crew Dragon vertical on the launch pad. Falcon 9 lifted off from the Kennedy Space Center’s Launch Complex 39A, the launch site for the Apollo 11 mission that put humans on the moon.”I would never have believed that this would ever happen,” Musk said, referring to using the same launch site. “It’s incredible history. I hope we go back to the moon soon.”
As Crew Dragon hurls through space, SpaceX will command the craft from its control center in Hawthorne, California, while NASA teams will monitor operations throughout the flight from the agency’s mission control center at the Johnson Space Center in Houston. Crew Dragon is slated to dock with the ISS around 6 a.m. Eastern time on Sunday.
The stakes for SpaceX are huge. Though the company has shaken up the stodgy aerospace industry by designing rockets for rapid reusability, and pioneering entertaining, informative live streams featuring young engineers, it’s never flown astronauts.
Saturday’s flight is a dress rehearsal for the first manned spaceflight from US soil since the Space Shuttle was grounded in 2011. The Crew Dragon includes a new emergency escape system, first tested in 2015, that’s designed to carry astronauts to safety if there’s an emergency.
Gwynne Shotwell, SpaceX’s president and chief operating officer, spoke Thursday evening to students at Northwestern University in Evanston, Illinois, her alma mater. She told a packed audience that she has taken to referring internally at SpaceX to the first two astronauts slated to fly on Crew Dragon as “the dads.”
“They are fathers. I think it is really important for all employees, all engineers and technicians at SpaceX to understand the precious—I don’t even want to call it a gift—the responsibility we’ve been given,” said Shotwell. “And we’re going to put the dads on top later this summer.”
For this weekend’s scheduled flight, a mannequin outfitted with sensors will be on board. Her name is Ripley, a tongue-in-cheek, Muskian reference to the protagonist of the Alien films. The company has always seen publicity and education as key to gaining public support. Shotwell said she looks at the Earth’s population and sees billions of potential customers for future SpaceX flights that feature tourists instead of astronauts.“The work we’re doing, and others as well, will completely change how we think about our world, our solar system, and candidly, life on Earth,” she said.

SpaceX is gearing up for over 300 missions in five years: CEO Elon Musk

After an updated version of the SpaceX Falcon 9 rocket lifted off from Florida's Cape Canaveral carrying Bangladesh's first communications satellite into orbit, its Founder and CEO Elon Musk on Sunday said his company is set for over 300 missions in five years.
The "Block 5" booster, the final substantial upgrade to SpaceX's Falcon 9 launch vehicle, was launched from NASA's Kennedy Space Centre on its maiden flight on Friday.

The rocket's first stage was successfully recovered, landing on the "Of Course I Still Love You" offshore droneship, about eight minutes after the launch, at an unmanned platform vessel in the Pacific Ocean.
"SpaceX will probably build 30 to 40 rocket cores for 300 missions over 5 years. Then the Big Falcon Rocket (BFR) takes over & Falcon retires. The goal of BFR is to enable anyone to move to moon, Mars & eventually outer planets," Musk tweeted on Sunday.
The "Block-5" booster is designed to be capable of 10 or more flights with very limited refurbishment as SpaceX continues to strive for rapid reusability and extremely high reliability,
"Rate at which things are getting more bizarre appears to be increasing. In the future, it will seem bizarre that we used to crash rockets into the ocean instead of reusing them," Musk added.
Falcon 9 rocket, aiming to bring astronauts to the International Space Station (ISS) in the future, came with many design changes to improve its reusability and reliability. Those changes may make engineers easier to refurbish its first stages for more flights.
The new rocket has improved its helium tanks submerged in liquid oxygen propellant tanks in the second stage. The helium tanks were ruptured in a pre-launch test on September 1, 2016, causing an explosion.
The Big Falcon Rocket, or BFR, which will be used to explore Mars -- a goal that Musk hopes to accomplish by 2022 -- will be built in the Port of Los Angeles.
According to media reports, the LA Board of Harbor Commissioners gave its unanimous approval to permit SpaceX to build the BFR Mars rocket at a new facility on Terminal Island at the Port of Los Angeles.
The report said the new rocket manufacturing facility would be built on a 19-acre parcel on the mostly artificial island that's part of the port. The facility would provide employment to as many as 700 people, according to SpaceX.
According to Musk, the huge new rocket would be nearly 350 feet tall and span 30 feet in diameter.
Last month, NASA's next planet-hunter, the Transiting Exoplanet Survey Satellite (Tess), was successfully launched on a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida.
Tess is expected to find thousands of new exoplanets orbiting nearby stars, including some that could support life.
