Weather permitting, the US-based rocket manufacturer will blast off from its base of operations at the Cape Canaveral Air Force Station in Florida.

SpaceX livestreams typically kick start about 15 minutes before the final launch countdown.
SpaceX has a narrow, two-hour-long window of opportunity for liftoff tomorrow, starting at 1.18am Eastern Time (6.18am BST).
A backup launch plan could see SpaceX’s Falcon 9 blast off into space on Wednesday, August 8, if things go awry tomorrow.
SpaceX said: “SpaceX is targeting launch of the Merah Putih satellite to a Geostationary Transfer Orbit (GTO) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.
“The two-hour launch window opens on Tuesday, August 7 at 1.8 am EDT, or 5.18 UTC.”
The communications satellite will be deployed into position by the Falcon 9 rocket approximately 32 minutes after liftoff.
Ahead of the launch, Zulhelfi Abidin, chief technology officer of Telkom Indonesia, said the new satellite will play a “vital role” in the country’s telecommunications infrastructure.
He said: “SSL has been an excellent spacecraft supplier and has completed the satellite construction ahead of schedule.
“We look forward to traveling to Florida to see the satellite launch later this summer.”
The Merah Putih will replace a Telkom-1 satellite launched into orbit in August 1999.
The first stage of the Falcon 9 will attempt to touch back down on Earth after successfully completing its mission.
The rocket will be intercepted by SpaceX’s mobile drone ship, the Of Course I Still Love You landing platform, in the Atlantic Ocean.
The Falcon 9’s first rocket stage used tomorrow previously supported the Bangabandhu Satellite-1 mission on May 11, 2018.
The May 11 launch marked SpaceX’s first use of the reusable Block 5 booster variant.
SpaceX founder Elon Musk told ArsTechnica at the time: “We are going to be very rigorous in taking this rocket apart and confirming our design assumptions to be confident that is indeed able to be reused without taking apart.
“Ironically, we need to take it apart to confirm it does not need to take be taken apart.”
The Merah Putih satellite launch also comes off the back of the Iridium-7 launch on July 27, last month.
The seventh instalment in the Iridium Next series of rocket launches delivered 10 Iridium Next satellites into Low-Earth Orbit (LEO).
The Iridium network of communications spacecraft is comprised of 11 satellites across six individual polar planes for a total of 66 connected satellites.
An Iridium-8 launch is outlined on SpaceX’s launch manifesto for sometime later this year, from Vandenberg Air Force Base, California.
