FALCON-9 1.2V will be launched with DRAGON spacecraft atop from Cape Canaveral ASF launch site SLC-40. Goal for this mission is resupplying for ISS.

It will be second launch of Dragon with supplies for ISS. SpaceX is designating its Falcon-9 1.2V rocket to carry on their contract for resupply of ISS. As usual, Dragon will take 3310 kg of payload:¬†Propellant for ISS engines to provide correct orbit, Oxygen and water, Spare parts and tools necessary for keeping station operational, Scientific instruments and research materials to¬†efficiently use valuable time at the station and last but not least – food and parcels for crew members. SpaceX will utilize Falcon-9 in 1.2 version with reengineered thrust for better performance but still powered by liquid fueled Merlin-1D engines and without more severe improvements. Falcon-9 is still waiting for adopting reusable technology on it’s second stage.
