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

CAPE CANAVERAL: 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 service.
The 23-story-tall jumbo rocket, carrying a cherry red Tesla Roadster from the assembly line of Musk’s electric car company as a mock payload, thundered off its launchpad in billowing clouds of steam and rocket exhaust at 3:45pm from 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. At least 2,000 spectators cheered the blastoff from a campground near Cocoa Beach, 8 kilometers from the space center.
Within three minutes, the Falcon Heavy’s two side boosters separated from the central rocket in one of the most critical points of the flight.
Then, capitalizing on cost-cutting reusable rocket technology pioneered by SpaceX, the two 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. Each rocket unleashed a double sonic boom as it neared the landing zone.
The center booster rocket, which SpaceX had predicted was less likely to be salvaged, slammed into the Atlantic at about 483 kilometers per hour, destroying two of its thrusters and showering the deck of the nearby drone landing vessel, Musk told a post-launch news conference.
Still, the Silicon Valley mogul known for self-deprecating understatement hailed the launch as a victory and “a big relief.”
“I had this image of this giant explosion on the pad, with wheels bouncing down the road and the logo landing somewhere with a thud. But fortunately, that’s not what happened,” he said. “Crazy things come true.”
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.
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, a partnership of Lockheed Martin and Boeing — for about a fourth the cost.
The demonstration flight put the 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 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 rocket is essentially constructed from three Falcon 9s bolted 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 Musk’s other transportation enterprise, Tesla.
The Tesla Roadster is supposed to be sent into solar orbit, on a path taking it as far from Earth as Mars. Adding to the whimsy, SpaceX planted a space-suited mannequin in the driver’s seat of the convertible.
Musk mused that “it may be discovered by some future alien race.” The white spacesuit was real, he said.

Greek researchers enlist EU satellite against Aegean sea litter

  • “All the targets were carried into the sea, the satellites passed by and we’re ready to fill out the first report”
  • Satellite data is provided free from the European Space Agency (ESA) and hours after the overpass targets should be detected from the Sentinel-2 satellite

LESBOS ISLAND, Greece: Knee-deep in water on a picture-postcard Lesbos island beach, a team of Greek university students gently deposits a wall-sized PVC frame on the surface before divers moor it at sea.
Holding in plastic bags and bottles, four of the 5 meter-by-5-meter (16 foot-by-16-foot) frames are part of an experiment to determine if seaborne litter can be detected with EU satellites and drones.
“This was the first big day,” says project supervisor Konstantinos Topuzelis, an assistant professor at the University of the Aegean department of Marine Sciences, said of the scene from last week.
“All the targets were carried into the sea, the satellites passed by and we’re ready to fill out the first report.”
The results of the experiment — “Satellite Testing and Drone Mapping for Marine Plastics on the Aegean Sea” — by the university’s Marine Remote Sensing Group will be presented at a European Space Agency symposium in Milan in May.
“Marine litter is a global problem that affects all the oceans of the world,” Topouzelis told AFP.
Millions of tons of plastic end up in the oceans, affecting marine wildlife all along the food chain.
“Modern techniques are necessary to detect and quantify marine plastics in seawater,” Topouzelis added, noting that space agencies have already been looking into how drones and satellites can help with the clean-up.
“The main advantage is that we are using existing tools,” which brings down costs and makes it easier to scale up, says Dimitris Papageorgiou, one of the 60 undergraduate and postgraduate students who worked on the experiment.
To prepare, the team gathered some 2,000 plastic bottles and lashed them to the frames. Other targets were crafted with plastic bags, as these are even harder to spot in the water and usually constitute the deadliest threat to Aegean marine life such as dolphins, turtles and seals.
In 2018, a first phase in the experiment was able to detect large targets of around 100 square meters from space.
This year’s experiment uses targets a quarter that size to test the smallest detectable area under various weather conditions.
“It was a crazy idea,” laughs Topouzelis.
“We knew that the European satellite system passes at regular intervals with a spatial resolution of 10 meters.”
In theory, then, the satellites should be able to detect the floating rafts of plastic the team pushed out to sea.
The University of the Aegean is working on the project with Universidad de Cadiz in Spain, CNR-Ismar in Italy and UK environmental consultants Argans Ltd.
Satellite data is provided free from the European Space Agency (ESA) and hours after the overpass targets should be detected from the Sentinel-2 satellite.
The project acts as a calibration and validation exercise on the detection capabilities of the satellites.
But even if relatively small patches of plastic garbage can be spotted from orbiting satellites, the problem of how to remove it from the sea remains.
Last year, a giant floating barrier five years in the making was launched off the coast of San Francisco, as part of a $20-million project to clean up a swirling island of rubbish between California and Hawaii.
But the slow speed of the solar-powered barrier prevents it from holding onto the plastic after it scoops it up.
