While SpaceX continued to launch its 2020 launch campaign, the company introduced another batch of Starlink Internet satellites to help the entire constellation existing in low-Earth orbit.The project was presented Thursday morning on a nine Falcon rocket tested in flight from the historic LC-3nineA.

Starlink V1.0 L11 will be SpaceX’s 100th mission, marking a major milestone in the company’s history since its design in May 2002 and the falcon 1’s first flight, the first rocket built through SpaceX, in March 2006.
This step, however, went to the SAOCOM 1B project that jumped to the beginning of the queue.
Since March 2006, SpaceX has experienced a nine5% release good fortune rate on ninenine flights they have made to date with their evolved Falcon 1, Falcon nine and Falcon Heavy models.SpaceX hopes to bring this trend to long-term fortune with its next-generation Starship/Super Heavy release system, which will help the company achieve its number one goal of colonizing Mars and turning humans into a multiplanetary species.
The first level of the Falcon nine rocket that introduced this project, the B1060.2 core, this designation comes from SpaceX’s internal nomenclature/numbering scheme, with the B1060 being the sixty falcon nine/heavy reinforcement core built through the company at its headquarters.in Hawthorne, California, and “.2” means the thruster was set up for its flight for the time being.
The B1060 was used in the past to orbit the third GPS Block III satellite for the US Space Force.But it’s not the first time On June 30, 2020.During this mission, the thruster landed safely on the deck of the “Just Read The Instructions” drone, which was then towed to Puerto Canaveral.Once at the port safely, the B1060 got rid of JRTI and took it back to the SpaceX facility at Cape Canaveral Air Force Base to be restored.
The B1060 was used again for this Starlink mission, which saw an entire batch of 60 Starlink Internet satellites deployed in low Earth orbit.
The Starlink V1.0 L11 project was the eleventh launch of the Starlink operational satellite to date, with a total of 593 V1.0 satellites already introduced as a component of the initial deployment phase of SpaceX’s satellite Internet constellation.This first phase will see 1,584 Starlink satellites introduced, several projects, followed by more stages of satellite deployment and launches.
SpaceX has begun to provide the opportunity to verify the beta edition of the Starlink Internet service to personal users, and the public beta will be presented later this year.Beta verification updates will be provided on the company’s website.
Each Starlink satellite has a flat-panel design with several high-speed phase antennas, a solar panel for orbiting energy production, and a star-by-star navigation system.A Krypton-powered Hall thruster is supplied for the area.propulsion and is used for orbit lifting maneuvers and exorbitant burns.
As in previous Starlink missions, the Starlink satellite will also have a solar visor, or visor, which will prevent sunlight from reflecting on most of the spacecraft frame in orbit and decrease its overall albedo/intrinsic brightness observed from the ground.in a time after the separation of the spacecraft.
Each operational Starlink satellite weighs approximately 260 kilograms (573 pounds), in a full batch of Starlink that weighs approximately 15,600 kilograms (34,380 pounds) at takeoff.Here are some of the heaviest payloads that can be launched on a Falcon nine when it’s in its reusable configuration.
The countdown began in the T-38 minute, when the launch manager interviewed the project teams to perform the thruster’s loading operations.When the “step” was made, the refrigerated RP-1 fuel (a form of high-quality kerosene) flowed to both levels of the Falcon nine launcher from 35 minutes before takeoff, with liquid oxygen load (LOX) in the first level.The LOX charge at falcon nine moment level began at T-16 minutes.
7 minutes before takeoff, the liquid oxygen pre-soups of the nine first-stage Merlin-1D engines were opened, allowing the LOX to pass through the engine tubing and condition the turbopumps for ignition. This process, called “engine cooling”, is used to prevent thermal shocks that can damage engines during startup.
In the T-1 minute, computers aboard the Falcon 9 carried out final checks on the vehicle’s systems and completed the pressurization of the tank before the flight.The release manager gave one last “attempt” to release T-45 seconds.
All nine Merlin-1D engines on the first tier ignited in T-3 seconds, and takeoff took off at T-0 after a quick final check through on-board computers to determine that all systems were nominally operational.
After taking off from the LC-3nineA, the Falcon nine began tilting downwards as it accelerated towards orbital speed.Approximately 1 minute and 12 seconds of flight time, the vehicle passed through the region of maximum aerodynamic voltage, or “Max-Q”.”During this part of the flight, the mechanical stresses on the rocket are at maximum.
The Falcon 9’s nine Merlin-1D engines continued to burn until approximately T2 minutes and 32 moments, when they all stopped during an occasion called MECO, or major engine shutdown.The separation of the terrain occurred soon after, with the engine ignition.Merlin vacuum engine at ground time in the T mark 2 minutes 43 moments When the engine started, the moment level continued to take the 60 Starlinks into a low Earth orbit, with an inclination of 53 degrees.
The 5-meter payload fairing of the Falcon nine rocket, which housed the payloads of the initial launch phases, was deployed approximately 3 minutes and 12 seconds after the start of the flight. After the separation, the two halves of the fairing descended to Earth to be recovered.through GO Ms. Tree, one of two ships spacex has at its disposal for refurbishment operations (the other is GO Ms. Chief).
As falcon level 9 and Starlink payloads continued to advance into low-Earth orbit, the Falcon B1060.2’s core returned to Earth to make a propellant landing on the unmanned “Of course I still love you”, stationed about 630 kilometers (391.4 miles).) downstream from the release site.
The first level an access burns approximately 7 minutes of flight, in order to slow down its descent and refine its trajectory towards the droneship.The burning on the last landing ended in the T mark 8 minutes 19 seconds, with the B1060.2 landing gently on the OCISLY deck under the force of a single Merlin-1D engine.
The Falcon 9’s second-stage Merlin Vaccum engine stopped 8 minutes and 51 seconds after the flight began, once known as SECO or Second Engine Cutoff, the only combustion of the mission’s second-stage engine.
At approximately 14 minutes and 47 seconds of flight time, the full batch of 60 Starlink satellites was deployed at the same time, marking the final touch of the project launch phase.
At this stage, SpaceX will begin conducting knowledge reviews of the Starlink satellite to ensure that all systems work as expected before performing orbit improvement operations.All satellites that cannot lift their orbit will be left in the initial deployment orbit, temporarily desorbing and decreasing the threat of collision.
The Starlink V1.0 L11 project is a dual-purpose component, with SpaceX also conducting a top-down 150-meter check with its prototype Starship SN6 vehicle at its launch and production facility in Boca Chica, Texas.The vehicle has recently been equipped with a number of Reaction Control System (RCS) thrusters and a single Raptor engine (Raptor SN29), which will drive the Starship vehicle off its release platform, in the air and in the air.contacting platform next to you, at the launch site.
SN6 points to the third Starship vehicle for a full verification flight, the other two being the Starhopper check bench (which performed a series of jump checks in July and August 2019, respectively) and the Starship SN5 prototype (which flew safely around 150 meters).August 4, 2020).
SpaceX is also pushing for the launch of the fourth GPS Block III satellite, which is expected to fly on a Falcon nine from Space Launch Complex 40 at Cape Canaveral Air Force Base in Florida no later than September 30.on Falcon nine rockets, this project will use a new Falcon nine first-stage thruster, which is expected to be the B1062.1.
SpaceX still aims to launch a total of 24 Starlink missions by the end of 2020.
