SpaceX blasts off powerful GPS satellite for US military

TAMPA, Florida -- A SpaceX rocket on Sunday blasted off a powerful GPS satellite for the US Air Force, marking its 21st and final launch for the year.

A SpaceX mission control operator counted down to liftoff as the white Falcon 9 rocket took off under sunny, blue skies at 8:51 a.m. from Cape Canaveral, Florida.

The launch sent the Global Positioning System III space vehicle (SV) satellite into space to join the Air Force's constellation of 31 operational GPS satellites.

It promises "three times better accuracy" and an extended 15-year operational life, said a SpaceX statement.

Billions of people worldwide depend on GPS to support financial, transportation, and agricultural infrastructure.

SpaceX said the rocket was a "rare, expendable" version of the Falcon 9 since it would not attempt to re-land the booster after launch, needing to reserve all the rocket fuel to propel the satellite to its distant orbit.

SpaceX's Falcon Heavy rocket soars in debut test launch from Florida

CAPE CANAVERAL, Florida - The world's most powerful rocket, SpaceX's Falcon Heavy, roared into space through clear blue skies in its debut test flight on Tuesday from a Florida launch site where moon missions once began, in another milestone for billionaire entrepreneur Elon Musk's private rocket company.

The 23-story-tall jumbo rocket, carrying a cherry red Tesla Roadster automobile into space as a mock payload, thundered off its launchpad in billowing clouds of steam and rocket exhaust at 2045 GMT (4:45 am in Manila) at the Kennedy Space Center in Cape Canaveral.

Boisterous cheering could be heard from SpaceX workers at the company's headquarters in Hawthorne, California, where a livestream feed of the event originated. Several hundred spectators packed a campground near Cocoa Beach, 5 miles (8 km) from the space center, to watch the blastoff.

Musk previously said one of the most critical points of the flight would come as two side boosters separated from the central rocket within three minutes of launch. That occurred seemingly without a hitch.

Then, capitalizing on cost-cutting reusable rocket technology pioneered by SpaceX, the two side boosters flew themselves back to Earth for safe simultaneous touchdowns on twin landing pads at Cape Canaveral Air Force Station about eight minutes after launch. The center booster was expected for a return landing on a drone ship floating at sea, but its fate was not immediately known.

Musk told reporters on the eve of the rocket's test flight that he would "consider it a win if it just clears the (launch) pad."

While the Falcon Heavy's initial performance appeared, by all accounts, to have been near flawless, it remained to be seen whether the upper stage of the vehicle and its payload would survive a six-hour "cruise" phase to high Earth orbit through the planet's radiation belts.

TURNING POINT 

The launch, so powerful that it shook the walls of the press trailer at the complex, was conducted from the same site used by NASA's towering Saturn 5 rockets to carry Apollo missions to the moon more than 40 years ago. SpaceX has said it aspires to send missions to Mars in the coming years.

The successful liftoff was a key turning point for Musk's privately owned Space Exploration Technologies, which stands to gain a new edge over the handful of rivals vying for lucrative contracts with NASA, satellite companies and the US military.

Falcon Heavy is designed to place up to 70 tons into standard low-Earth orbit at a cost of $90 million per launch. That is twice the lift capacity of the biggest existing rocket in America's space fleet - the Delta 4 Heavy of rival United Launch Alliance (ULA), a partnership of Lockheed Martin Corp and Boeing Co - for about a fourth the cost.

The demonstration flight put the Falcon Heavy into the annals of spaceflight as the world's most powerful rocket in operation, with more lift capacity than any space vehicle to fly since NASA's Saturn 5, which was retired in 1973, or the Soviet-era Energia, which flew its last mission in 1988.

Propelled by 27 rocket engines, the Falcon Heavy packs more than 5 million pounds of thrust at launch, roughly three times the force of the Falcon 9 booster rocket that until now has been the workhorse of the SpaceX fleet. The new heavy-lift rocket is essentially constructed from three Falcon 9s harnessed together side by side.

Going along for the ride in a bit of playful cross-promotional space theater was the sleek red, electric-powered sports car from the assembly line of Musk's other transportation enterprise, Tesla Inc.

The Tesla Roadster is supposed to be sent into a virtually indefinite solar orbit, on a path taking it as far from Earth as Mars. Adding to the whimsy, SpaceX has planted a space-suited mannequin in the driver's seat of the convertible.

Whether the car makes it onto its planned trajectory will not be known before late on Tuesday, SpaceX said. The roadster, which carries a plaque inscribed with the names of more than 6,000 SpaceX employees, could instead end up in Earth orbit.

The launch followed an impressive run of successful paid missions - 20 in all since January 2017, when SpaceX returned to flight following a 2016 launchpad accident that destroyed a $62 million rocket and a $200 million Israeli communications satellite that it was to put into orbit two days later.

SpaceX had previously announced plans to eventually use the Falcon Heavy to launch two paying space tourists on a trip around the moon and back. Musk said on Monday he was now inclined to reserve that mission for development of an even more powerful SpaceX launch system, the Big Falcon Rocket, or BFR, which he said was proceeding more quickly than expected.

SpaceX lands rocket on ocean platform for first time

MIAMI, United States – After four failed bids SpaceX finally stuck the landing Friday, powering the first stage of its Falcon 9 rocket onto an ocean platform where it touched down upright after launching cargo to space.

Images of the tall, narrow rocket gliding down serenely onto a platform that SpaceX calls a droneship sparked applause and screams of joy at SpaceX mission control in Hawthorne, California.

"The first stage of the Falcon 9 just landed on our Of Course I Still Love You droneship," SpaceX wrote on Twitter, after launch from Cape Canaveral, Florida at 4:43 pm (2043 GMT).

 NASA spokesman George Diller confirmed that the rocket had successfully landed, just minutes after the Falcon 9 propelled the unmanned Dragon cargo craft to orbit, carrying supplies for astronauts at the International Space Station.

SpaceX has once before managed to set the rocket down on land, but ocean attempts had failed, with the rocket coming close each time but either crashing or tipping over.

Speaking to reporters afterward, SpaceX CEO Elon Musk said that being able to return costly rocket parts for repeated use, instead of jettisoning them into the ocean after each launch, will make spaceflight less expensive and less harmful to the environment.

"It is just as fundamental in rocketry as it is in other forms of transport such as cars or planes or bicycles or anything," said Musk, who also runs Tesla Motors.

Musk said it costs around $300,000 to fuel a rocket, but $60 million to build one.

"If you have got a rocket that can be fully and rapidly reused, it is somewhere on the order of a 100-fold cost reduction, in marginal costs," he said, adding that he hoped his competitors would follow suit.

Obama leads praise

President Barack Obama led the praise, tweeting: "Congrats SpaceX on landing a rocket at sea. It's because of innovators like you & NASA that America continues to lead in space exploration."

Also on Twitter, Canadian astronaut Chris Hadfield said: "Landed! That is amazing! World-leading ability, proven.

"Opens the imagination to what is possible."

    Congrats SpaceX on landing a rocket at sea. It's because of innovators like you & NASA that America continues to lead in space exploration.

Friday's breakthrough came after a closely watched return-to-flight mission, SpaceX's first cargo delivery since June 2015, when the Falcon 9 exploded just over two minutes after liftoff, destroying the rocket and the supply ship.

SpaceX blamed the blast on a faulty strut in the Falcon 9's upper booster, which allowed a helium bottle to snap loose, causing the explosion of the rocket, cargo ship and all its contents.

It has since upgraded its Falcon 9 rocket and changed its protocol to avoid a repeat.

This time, the gumdrop-shaped capsule was packed with nearly 7,000 pounds (3,100 kilos) of supplies for the astronauts living in orbit.

The Dragon's cargo includes an inflatable space room astronauts will test in microgravity.

Known as the Bigelow Expandable Activity Module, the chamber will be temporarily attached to the space station.

Lab mice for experiments and lettuce seeds for growing at the orbiting outpost were also included in the spacecraft, which should arrive at the International Space Station early Sunday.

'Proven it can work'

Musk said the rocket was being welded onto the droneship with metal shoes, so as not to tip over as it made its way back to land.

Next, the booster will undergo a series of tests, including 10 static fires on the launchpad, before engineers decide if it is in good enough shape to fly again.

If so, the next launch of the same booster could be in the next two to three months, Musk said.

"In the future, hopefully we will be able to relaunch them in a few weeks."

In the meantime, SpaceX will keep working on perfecting its landing techniques, whether on ocean or solid ground, since both options need to be available to suit different types of missions.

Musk said about half of SpaceX's rockets will need to land at sea, and it might take a few years to work out all the kinks.

"But I think it is proven that it can work," he said.

"We will get it to a point where it is routine to bring it back and the only changes to the rocket are to hose it down, give it a wash, add the propellant and fly it again."
