A Falcon 9 rocket with a thunder, sky-light, Preston Blastoff from Cape Canaveral, fired Saturday in the classroom with the Dragon Cargo Capsule in search of the International Space Station on Saturday.
Less than nine minutes later, the first stage booster of the rocket fell from the sky and just carried out a pinpoint propulsor landing in the offshore, using the same vehicle using this same rocket using another rocket for NASA Resupply established the platform for the mission.
The 213-foot-tall (65-meter) rocket was lifted from its nine Merlin 1D main engines with a flash at 2:48:58 pm EDT (0648: 58 GMT), almost the same moment when rotated by the orbital plane of Cape Canaveral Space Station.
Falcon 9 tilted to the north-east to align with the flight path of the space station, giving stress of 1.7 million pounds in the form of a roaring sky in a starry sky. Less than 2:30 minutes later, the rocket’s first stage booster was shut down and separated for starting a line on Earth, the target of the SpaceX drone ship “Course I Still Love You” was 14 miles (22 kilometers) The Cape Canaveral of the Atlantic Ocean, formerly placed in the east.
The first stage burned three of its engines – to start reverse-course burn to return to Boost and return to Florida’s Space Coast, while the upper phase of Falcon 9 continued with the primary purpose of Saturday’s mission – a dragon Packaged with 5,472 pounds (2,482 kg) of supplies, provisions, and experiments for the delivery station and its six-crew in the class of Cargo Craft.
The interactive exhaust plume produced a significant light effect from the Merlin engine of the first and second phase of Falcon 9, which showed the presence of a cosmic nebula above the Florida spacecraft.
In the second stage, the firing was held for six minutes to keep the dragon supply vessel in the first supply class. Moments later, the automatic spacecraft emits from the upper phase of Falcon 9 and opens up two power-generating solar panels, which in the next two days the platform is set up for the sequence of thrust firing, At the Space Station of the end of the space shuttle approaches at the beginning of Monday.
Astronauts at the station will use a robotic arm to capture the Dragon spacecraft, which will be transported to a port on the Harmony module for a month-long stay.
Dragon Cargo Craft, which uses the same pressure segment, which first flew to the space station in August 2017, which is a host of crew supplies, spare parts, and experiments, from biological investigations to spaceflight on the body. Takes effect on a device by taking effects. For the first time in a US military experiment developed in concert with NASA to demonstrate X-ray communication in space, measuring carbon dioxide in the Earth’s atmosphere.
There is a 17th cargo launch at the station by Spacecope Mission, SpaceX, which is at the beginning of 2020, contract of $ 3.04 billion for 20 cargo delivery. SpaceX follow-on contract for at least six and launches missions for the station through 2024, $ 2.6 billion to make the advanced Crew Drug Spaceship from the space station and to the astronauts. Contract of
The Dragon spacecraft is scheduled to launch home research samples and other equipment to leave the space station on June 3 and to splash in the Pacific Ocean.
Successful landing on the drone ship of Booster’s early stage of the Falcon 9 rocket after Saturday’s liftoff indicated the beginning of the launch of the SpaceX launch for the next flight, which is not present at Cape Bavarwal before July 8. Is scheduled for.
Officials said in a press conference on Saturday morning that NASA and SpaceX have agreed to use the first phase to fly on the next cargo mission Saturday, which is named SpaceX CRS-18, and possibly in December, CRS-19 After the launch
The first stage of the rocket, which is at the height of 15 stories, made its first journey on the shore of space and the back of the area. SpaceX has reused the first step booster from the first three times, and the company says that the latest generation of Falcon 9 Booster can fly up to 10 times before the need for a significant renovation.
SpaceX asked Friday to launch an attempt to resolve the issue of power on the drone-ship, which is a soccer field-shaped ocean-platform that is used for rocket landing at sea. the first time that SpaceX had delayed the launch to ensure the recovery of the first phase for reuse, a practice which the company says is that it reduces costs and produces rocket production at the company headquarters in Hawthorne, California. Reduces the rhythm.
“This is a case-by-case decision,” said Hans Koenigman, Vice President of Space and Flight Reliability of SpaceX. “This is a new vehicle. Booster is worth a lot of money. We want to fix it. This is a greater part of the mission, and it is important to appear. For the next CRS mission, it is specially planned. We will see how it runs, depends on inspection and some other innovation items. ”
SpaceX has left its Falcon 9 Booster before landing, recently on a mission last year. Bad weather and rough seas prevented the SpaceX drone ship from reaching a remote offshore landing site in the Atlantic Ocean in March 2018 to carry the His pass 30W-6 communications satellite.
SpaceX was selected to proceed with the launch on schedule without fixing the first stage booster.
After an attempt to launch Friday, SpaceX returned the drone-ship to Port Canaveral to repair it. On Friday afternoon, the ship went off again.
Landing location was unusual for the first phase of Falcon 9 for Saturday’s mission. Most re-built purposes in the space station do not use the full capacity of the Falcon 9 rocket of SpaceX, leaving enough remaining explosives for the first stage for the reverse course and returning to Cape Canaveral for an onshore landing.
But the Landing Zone 1 of SpaceX, located at Cape Canaveral Air Force Station, is not available for this launch after the April 20 explosion of the crew dragon capsule of SpaceX during the ground test. According to Hans Königsmann, Vice President of SpaceX, the reliability of construction and construction, parts of the landing zone are still closed for security reasons.

For massive expeditions that need to be promoted more than the first stage, SpaceX usually deploys the drone ship hundreds of miles, allowing rockets to arch on a ballistic trajectory, then landing without returning to Florida. To slow down.
A parking lot for the drone ship in the south of Launching Pad 40, around 17 miles (28 kilometers) in the Atlantic Pad allowed the Falcon 9 first step to follow a return profile, which boosters in Landing Zone 1 There was a plan to bring back.
A “close-in” drone landing was completed before landing a drone ship after a launch from the Vandenberg Air Force Base in California in Dmb.
Because the drone ship was very close to the shore, it was time for SpaceX to solve the issue of electricity on the landing platform for another launch attempt on Saturday.
NASA agrees with the decision.
NASA manager Kenny Todd of Space Station Operations told reporters after the launch on Saturday that a one-day delay will not have any meaningful impact on the science or maintenance program of the station.
“Finally, when he said that this is what he wanted to do, knowing that today (and) (weather) situation looked better today, I thought that it was a fine business,” Todd he said. “From a space station program, if we get off the pad today, then it will be excellent for our research, and we will be able to move ahead with our mission.
“The situation was different from the standpoint of a station, we would certainly have been engaged in that conversation at a different level,” said Todd. “But it certainly did not feel like it was necessary tomorrow.”
The launch team of SpaceX also faced the threat of storms during Friday’s countdown and a helium link in the ground equipment on the launch pad. It was revealed that neither the issue would be possible to stop the launch on Frdy, However, SpaceX wanted to recover the first stage.
The first phase of Falcon 9 on the previous cargo launch, SpaceX CRS-16, faced a malfunction during the descent in December, to make it systematically switched locally at the landing place from Cape Canaveral to Landing Zone 1. Got forced
The booster was intact, but it slipped into the sea. SpaceX extended the phase back to the port, but the rocket was not designed to reuse after landing in saltwater.
SpaceX planned to blow up the booster from the Vandenberg Air Force Base in California earlier this year, in which three Canadians were on the mission of deploying radar set observation satellites in class. This launch was scheduled for February, but in December the booster’s landing disturbance forced SpaceX to find a separate rocket for the RedRat mission, which delayed its liftoff for months.
The launch of Radarsat Nakshatra Mission from California has now been set for June 11, using the Falcon 9 booster which was first launched from Florida in March.
Todd said that NASA had “vested interests” in the recovery of a successful first phase after Saturday’s cargo launch.
Todd said, “We need it and intend to use it for SpaceX-18, and certainly for 19”. “Therefore, from our point of view, there was a difference. This is the reason behind the mind too.
