SpaceX will try to fly the same rocket for the third time on Sunday

The attempt to launch a Vandenberg Air Force Base Falcon 9 rocket Sunday in California, with a main launch window of 1:32 p.m. ET (18:32 UTC) until 2pm ET (19:00 UTC UTC), it is important for many reasons.

For one, this will be the 19th launch of the 2018 company, and if successful, it will break SpaceX's record for most missions flown in a calendar. With a handful of launches remaining in the manifesto in December, SpaceX quickly flies so many 22 rockets this year. This means that SpaceX has solved productions and operations that have prevented it from launching more than eight rockets a year before 2017, and that last year did not fly.

Perhaps more importantly, a successful flight Sunday would mark the third flight of this particular stage of the Falcon 9 rocket. This core first flew on May 11, for the Bangabandhu-1 mission, and again on August 7 for the Merah Putih mission. Now, for the first time, SpaceX will try to fly the same first stage (and its nine Merlin motors) for the third time.

Such a heroic rocket three times in less than seven months – would bring the company closer to its cost-targeting goal to fly every Falcon 9 rocket 10 times between major renovation. This became possible after the company introduced a final variant of its Falcona 9-booster, called Block 5, which engineers designed for optimal reuse. (The May-flight of this rocket core marked the first time in Block 5 variant of the Falcon 9 launched). As only one (very) smallest example of time and cost reduction efforts, SpaceX does not wash the first stage of the rocket between uses, which explains why the lower two thirds of the reunited rocket appear sung, but the top third is old white That is, because the upper stage and load load are new for each flight.

Finally, the Sunday mission is remarkable due to its load-there are many of them as part of the Space Side SSO-A mission. SpaceX will seek to set up a record of US releases for most satellites in space at a time, with 15 microscopes and 49 cubes of business and regulated organizations around the world. (Two of these, interestingly, are from Kazakhstan, a country that hosts many of the launches of the Russian space agency).

A company called Spaceflight organized the four-tone manifesto for Sunday. It designed the load load and coordinated various satellites for when the mission reached a solar-sink polar orbit at a height of 575km. Deployment of the satellites will begin about 13 minutes after removal and will finish about 30 minutes after that point.

SpaceX will again want to recover this boom through the joke Just read the instructions located in the Pacific Ocean. If successful, we can probably wait to see this first phase make an unprecedented fourth flight ever in 2019.

The e-mail address must start about 15 minutes before the window opens.
