SpaceX posts images of historic launch as Starman heads for the Asteroid Belt

A day after SpaceX's Falcon Heavy blasted into space, the private spacefaring company has posted some spectacular images of the launch as well as updating the status of the Tesla Roadster that acted as ballast payload. In a Twitter post, CEO and Founder Elon Musk confirmed that the second stage of what is now the world's most powerful rocket fired successfully, sending the car and its dummy driver into an orbit that will take it well into the Asteroid Belt. 
On February 6 at 3:45 pm EST, the first Falcon Heavy rocket lifted off from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center, Florida on a demonstration mission. Due to the tremendous complexity of the new booster and the 50/50 chance that the mission might end in failure, no active satellite was carried in the nose cone of the vehicle. Instead, Mr Musk's own Tesla Roadster was used as ballast in a gesture that he characterized at a post-launch press conference as a ridiculous bit of fun.
At the conference, Musk confirmed that the core rocket that made up the center of the three-part first stage of the Heavy did not have enough propellant aboard to make a soft landing, and hit the water at about 300 mph (480 km/h). He went on to say that, if the onboard cameras survived, "There could be some pretty fun footage." 
Musk went on to say that neither of the recovered side boosters that successfully landed at Cape Canaveral, Florida will be reused because they were not built for commercial missions. They are Block Four versions of the Falcon 9, and SpaceX will be using only Block Five versions from now on.
Also, during yesterday's conference, Musk expressed concern about the second stage of the rocket, which spent five hours parked in the Van Allen Belt before it restarted its Merlin engine for the third time to escape Earth's gravity. The Van Allen Belts are regions of intense radiation created by cosmic ray particles captured by the Earth's magnetic field. They act as a protective shield for the planet, but they can be a hazard for spacecraft that do not make a quick transition of the belts.
In this case, the second stage was not adversely affected, and fired as scheduled. It expended its propellant entirely, causing it to not only reach escape velocity, but also to reach an orbit that will circle the Sun at a distance between 91 million mi (150 million km) and 240 million mi (390 million km) – well into the Asteroid Belt between Mars and Jupiter, and almost as far out as the orbit of the dwarf planet Ceres. 




The Tesla Roadster atop the stage was the focus of media attention, especially after SapceX livestreamed video from the cameras mounted around it. The car has a spacesuited mannequin called Starman at the wheel and even includes a tiny Roadster with a tiny Starman.
"That will really confuse them" said Musk, referring to any future space travelers that might come across the Roadster.
Musk said that the spacesuit worn by Starman is a fully functional production model that took three years to design. He went on to say that the problem was to make a suit that works and looks good.
According to Musk, the battery aboard the Roadster was good for only 12 hours after launch, which is confirmed by the YouTube video that has switched from live feed to a four hour, 40 minute recording.
When asked about the price of the Falcon Heavy project, Musk said that it had estimated development costs of over US$500 million. The company is now transitioning from the Falcon 9 and Heavy as it concentrates more on developing the BFR, which he estimates will fly in three or four years.

Falcon Heavy takes off on its maiden mission

Falcon Heavy lifting off
Commercial space travel took a quantum leap forward today as SpaceX's Falcon Heavy rocket made its maiden flight. At 3:45 pm EST, the world's most powerful operational booster lifted off from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center, Florida on a demonstration mission intended to gather information about the reusable launch system before it goes into service. Today's launch came after a two-hour and 15 minute delay due to high-altitude shear winds that were outside the rocket's safety parameters. During liftoff, the 27 Merlin 1D engines of the Falcon Heavy's three Falcon 9 core boosters generated 5,548,500 lb of thrust as they gulped down supercooled liquid oxygen and kerosene. Two minutes and 29 seconds into the flight, the two outboard boosters shut down and then separated from the central core four seconds later. The latter shutdown at the three minute and four second mark, then the second stage separated three seconds after.The second stage then fired for five minutes and 16 seconds, followed by a second burn for 30 seconds. Once the orbital maneuver was executed, it marked a first for SpaceX as its unique payload separated and was set on an elliptical interplanetary trajectory around the Sun that will send it as far as the orbit of Mars.

Because the Falcon Heavy was only given a 50/50 chance of success, SpaceX decided not to risk a functioning spacecraft. In such a situation, it's usual to swap out the satellite with ballast made of blocks of steel or concrete, but in a whimsical move, the company used SpaceX CEO and Lead Designer Elon Musk's midnight-cherry Tesla Roadster. This marks either the first time that a motor car was sent into space or the fourth, if you count the three Lunar Rovers carried on the last three Apollo lunar landing missions in the early 1970s.
In the driver's seat of the Roadster is a mannequin, named "Starman" after the 1972 David Bowie song, who is dressed in one of the spacesuits that will be worn by the passengers and crew on SpaceX's manned dragon missions. In addition, Bowie's hit "Space Oddity" was playing on the car's soundtrack, though in the vacuum of space, there won't be anyone to hear it. However, in a nod to The Hitchhiker's Guide to the Galaxy, the words "Don't Panic" were displayed on the dashboard screen in large, friendly letters.No details were given about the Roadster itself, but it's likely that it was modified to make it suitable for space travel by removing the lithium ion battery banks or replacing them with dummies. Though the Roadster is headed out toward Mars, its trajectory is such that it has no chance of colliding with the Red Planet.


In keeping with SpaceX's policy of developing a fully reusable launch system, the two side boosters, which had already flown before, executed a reentry and landing maneuver to bring them down on SpaceX's Landing Zones 1 and 2 at Cape Canaveral Air Force Station, Florida to the cheers of the crowd outside of Mission Control. Meanwhile, the center core attempted a sea landing on the company's "Of Course I Still Love You" droneship in the Atlantic Ocean.Update: Musk has confirmed in a press conference following the launch the landing of the middle core was unsuccessful, as two of the three engines failed to fire and the booster slammed into the ocean at 300 mph (482 km/h).
