SpaceX successfully launches Falcon Heavy
In ‘one of its most difficult launches’ to date, the rocket’s payload included 24 experimental satellites and an atomic clock for Nasa
Cape Canaveral — SpaceX launched its Falcon Heavy rocket on Tuesday from Kennedy Space Centre in Florida, carrying 24 experimental satellites in what Elon Musk’s rocket company called one of the most difficult launches it has attempted.
The rocket blasted off to cheers from onlookers at 6.30am GMT after a three-hour delay from the original launch time late on Monday.
The boosters separated safely as the craft began its six-hour mission to deploy the satellites.
The two-side booster rockets returned safely to Earth, landing on adjacent Air Force landing pads, but the rocket’s centre booster missed its mark, crashing into the Atlantic ocean.
Musk, who predicted trouble with landing the centre booster on SpaceX’s drone ship in the Atlantic, said on Twitter early on Tuesday, “It was a long shot.”
The mission, dubbed Space Test Programme 2 (STP-2), is the third for the Falcon Heavy rocket, which SpaceX describes as the most powerful launch system in the world.
It was commissioned by the US department of defence, the key contractor for commercial space companies such as SpaceX. The company is putting satellites into orbit for agencies including Nasa and the National Oceanic and Atmospheric Administration (NOAA), defence department laboratories, universities and a non-profit organisation, SpaceX said.
The mission is one of the most challenging in SpaceX history, with four separate upper-stage engine burns and three separate orbits to deploy satellites, the company said on its website.
The payloads on the satellites Falcon Heavy is putting into orbit include an atomic clock Nasa is testing for space navigation; another testing new telescope technologies; and a solar sail project, LightSail, part-funded by the Planetary Society, a non-profit organisation headed by Bill Nye, The Science Guy on television presentations.
The LightSail is a crowdfunded project that aims to become the first spacecraft in Earth’s orbit propelled solely by sunlight, the society, which has championed solar propulsion for decades, says on its website.
Falcon Heavy is the most powerful operational rocket in the world “by a factor of two”, SpaceX says on its website. It has the ability to lift into orbit nearly 64 tonnes — more than a 737 jetliner loaded with passengers, crew, luggage and fuel.
According to the website, only the Saturn V moon rocket, last flown in 1973 from the same launch pad, delivered more payload to orbit.
