For a birds-eye view of where it all started, watch the cool close-up launch video, below taken from within the Atlas pad security fence.
Indeed the launch precision was so good that mission controllers at NASA’s Jet Propulsion Lab in Pasadsena, Calif., have announced they postponed the first of six planned course correction burns for the agency’s newest Mars rover by at least a month. The firing had been planned for some two weeks after liftoff.
Curiosity is merrily sailing on a 254 day and 352-million-mile (567-million-kilometer) interplanetary flight from the Earth to Mars that will culminate on August 6, 2012 with a dramatic first-of-its-kind precision rocket powered touchdown inside Gale Crater.
“This was among the most accurate interplanetary injections ever,” said Louis D’Amario of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. He is the mission design and navigation manager for the Mars Science Laboratory.
Video Caption: View from inside the Pad 41 Security Fence at Cape Canaveral. Shot by a Canon 7D still camera during the launch of the Atlas V rocket carrying the MSL Curiosity rover to Mars. Thanks to a sound trigger my camera started firing at three frames per second from just after main engine ignition up until the exhaust plume finally envelops the camera and deadens all sound around it. The frames have been slowed down quite a bit for dramatic effect. Enjoy seeing what it is like for us media personnel who set out our remote cameras for launches at Kennedy Space Center and Cape Canaveral, Florida. Credit: Chase Clark/shuttlephotos.com
As of midday Friday, Dec. 2, the spacecraft had already traveled 10.8 million miles (17.3 million kilometers) and is moving at 7,500 mph (12,000 kilometers per hour) relative to Earth and at 73,800 mph (118,700 kilometers per hour) relative to the sun.
An interesting fact is that engineers deliberately planned the spacecraft’s initial trajectory to miss Mars by about 35,000 miles (56,400 kilometers) so that the Centaur upper stage does not hit Mars by accident. Both Centaur and Curiosity are currently following the same trajectory through the vast void of space and the actual trajectory puts them on course to miss Mars by about 38,000 miles (61,200 kilometers).
The Centaur has not been thoroughly cleaned of earthly microbes in the same way as Curiosity – and therefore cannot be permitted to impact the Martian surface and potentially contaminate the very studies Curiosity seeks to carry out in searching for the “Signs of Life”.
For the 8.5 month voyage to Mars, Curiosity and the rocket powered descent stage are tucked inside an aeroshell and are attached to the huge solar powered cruise stage.
The cruise stage is rotating at 2.05 rounds per minutes and is continuously generating electric power – currently about 800 watts – from the gleaming solar arrays. It also houses eight miniature hydrazine fueled thrusters. The propellant is stored inside titanium tanks.
The historic voyage of the largest and most sophisticated Martian rover ever built by humans seeks to determine if Mars ever offered conditions favorable for the genesis of microbial life.
Curiosity is packed to the gills with 10 state of the art science instruments that are seeking to detect the signs of life in the form of organic molecules – the carbon based building blocks of life as we know it.
The car sized robot is equipped with a drill and scoop at the end of its 7 ft long robotic arm to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into two distinct analytical laboratory instruments inside the rover.
