SpaceX cancels Rocket Launch during second scheduled launch event

On February 25, SpaceX cancelled its second attempt to launch Falcon 9 rocket, owing to issues pertaining apparently to the installation of booster containing super-cooled liquid oxygen.

The two-stage rocket was supposed to carry a powerful communications satellite. The SES-9 commercial satellite was scheduled to be launched at 6:47 p.m. from Florida's Cape Canaveral Air Force Station. The launch of Luxembourg-based company SES’ satellite had been earlier cancelled on February 24 as well.

SpaceX also plans to land the first stage of Falcon 9 rocket involved in this mission on a landing pad in sea. However, it had still not been revealed that when will the rocket will be launched now, according to SpaceX's Falcon 9 Product Director, John Insprucker. The earlier cancellation of the launch also happened due to the problems associated with liquid-oxygen propellant.

During the earlier cancellation, the SpaceX representatives stated, “Out of an abundance of caution, the team opted to hold launch for today to ensure liquid oxygen temperatures are as cold as possible in an effort to maximize performance of the vehicle.”

The mission of Falcon 9, whenever it will be launched, will be to transmit SES-9 satellite to geostationary transfer orbit (GTO). SpaceX will make a fourth attempt to land the first stage of the rocket on an autonomous spaceport drone ship, named as ‘Of Course I Still Love You’, which is one of the two ships of the company that are located in the Atlantic Ocean offshore the coast of Florida.

SpaceX has already failed in its three previous attempts to land the first-stage rocket at a landing pad in sea. However, the company managed to successfully land a first-stage rocket on the land at Cape Canaveral in December 2015.

SpaceX team aims to successfully land the first-stage rockets are aimed at refurbishing them and using them for further launches. This will reduce the expenditure of launching a rocket by a factor of 100, according to Elon Musk, SpaceX founder and CEO.
