US space firm SpaceX is attempting to make history on Friday with the first launch of an already-used Falcon 9 rocket into space.
The two-stage rocket is scheduled to blast off at 6:37 p.m. EDT (4:07 a.m. Indian time) from the Kennedy Space Centre in Florida to deliver a communications satellite into orbit for Luxembourg-based satellite operator SES.
"The SES-10 mission will mark a historic milestone on the road to full and rapid reusability as SpaceX attempts the world's first reflight of an orbital class rocket," Xinhua news agency quoted the California-based company as saying in a statement.
Previously, the first stage of the rocket for the SES-10 mission flew in a cargo resupply mission to the International Space Station cargo for the the US space agency NASA in April 2016.
This time, the first stage will once again attempt a landing on the "Of Course I Still Love You" droneship that will be stationed in the Atlantic Ocean.
The second stage, which is expendable or single use, will send the SES-10 satellite to a geostationary transfer orbit.
Once in position, the satellite will provide telecommunications services to Latin America.
SpaceX achieved a space industry first in December 2015 when its Falcon 9 rocket booster successfully landed upright on solid ground at Cape Canaveral, Florida, after launching 11 small satellites into orbit.
The feat has since been repeated both on land and at sea, but SpaceX has yet to re-fly one of its used rockets.
SpaceX's rival firm, Blue Origin, owned by Amazon founder Jeff Bezos, successfully completed similar rocket recovery tests, but all of its missions were suborbital, not orbital, ones.
SES has been known to be "a strong supporter" of SpaceX's approach to reusability over the years. Back in 2013, it was the first company to launch a commercial satellite on a Falcon 9 rocket.
The satellite operator hailed the launch as "one step closer to rapid rocket reusability" and "one step closer to faster, easier access to space."
"Reusable rockets will not only drive down the launch cost," it said in a statement.
"They will also allow a higher launch frequency, which will definitely bring a new agility and competitive edge to the satellite industry."
