Private space flight companies are preparing to launch a third set of satellites, and SpaceX is continuing its rapid launch rhythm. Interstellar satellite In just three weeks. The new batch will join the giant constellation that has been in orbit later today (June 26) and you can watch it online.
A SpaceX Falcon 9 rocket will launch the Starlink mission from Space Launch Site 40 at Cape Canaveral Air Force Base in Florida. The scheduled departure time is no earlier than 4:18 pm. Eastern Daylight Time (2018 GMT).

This flight is SpaceX’s tenth dedicated Starlink launch and the eighth such mission in 2020. This is also the 11th launch of SpaceX in 2020, and the company has launched a record four times in the past four weeks. This rocket manufacturer from California The historic launch of two NASA astronauts —Doug Hurley and Bob Behnken – May 30, has not slowed down since. At the end of June, SpaceX still plans to launch two more launches before the July 4 holiday. In addition to today’s launch, the company expects to launch upgraded GPS satellites for the US Space Force on June 30.
But first, it will launch another set of Internet radiation satellites. Like the previous launch, the payload will contain other passengers. As part of the SpaceX ride plan, this flight carries two BlackSky satellites as part of the ride agreement with Spaceflight Inc.
SpaceX tweeted recently As part of the ride-sharing plan, more than 100 space shuttle flights have been scheduled. Spaceflight Inc. is such a customer with multiple bookings, he arranged the itinerary for BlackSky.
The rocket nose cone contains a stack of 57 Starlink satellites and two Earth observation satellites for BlackSky. This is the second official ride-sharing mission under SpaceX’s new ride-sharing plan (although the company has previously carried out Shared missions by car).

Today’s mission star is SpaceX’s other four flights. The booster named B1051 by SpaceX has previously been launched 2019 Demo-1 mission, It dispatched an unmanned crew Dragon spacecraft to the International Space Station, Three Earth observation satellites Canada, there are two Interstellar mission this year.
SpaceX regularly launches the used Falcon 9 booster, and builds an experienced rocket team, and flew many times. Prior to the company’s latest launch on June 13, SpaceX deviated slightly from its typical pre-launch preparations, and did not launch the Falcon 9 rocket before taking off. This routine test is called Static fire testIt needs to refuel and briefly ignite the rocket’s 9 engines while keeping it on the pad.
However, SpaceX chose to test the B1051 on fire before today’s flight. The reason for the protocol change is unclear, although the company’s flight-proven booster fleet has a proven track record in reliability.
To date, SpaceX’s Falcon 9 aircraft has flown 87 times, many of which were carried out using refurbished boosters. The company has proved The same booster can launch and land five timesThis was first seen in the last Starlink launch on June 3. The booster is expected to fly again soon.
The company’s first five attempts to launch and land a rocket did not go well, because the rocket encountered an engine abnormality in flight and missed the landing on the drone ship. Later, the abnormal phenomenon was attributed to the residual cleaning agent remaining inside the engine parts. Since then, SpaceX has changed the refurbishment procedure and successfully launched and recovered the same booster five times.
SpaceX’s increasing launch rhythm prompted the company to rely on two drones operating in the same ocean. The company’s drone “just read the instructions” recently moved from its former home in the Port of Los Angeles, California to Port Canaveral. Before the first booster capture, the ship underwent some sweet upgrades, including a new on-board camera, which can continuously see the booster landing on the deck.
The SpaceX Florida Fleet has added “read only instructions”, which means that the company can now launch (and capture) more rockets.

The goal of SpaceX’s Starlink project is to provide continuous high-speed Internet access to users around the world, especially those in remote and rural areas. The company aims to achieve this goal through the increasing constellation of satellites in orbit.
Elon Musk, founder and CEO of SpaceX, said the company will need at least 400 Starlink satellites in orbit to provide “smaller” broadband coverage and at least 800 to provide “medium” coverage. The launch will bring the number of Starlink satellites in orbit to 597, which is more than half of the medium coverage target.
The weather posted today looks promising, with only a 30% chance Weather violationAccording to the forecaster of the 45th Meteorological Squadron. Launching from Florida in the summer afternoon can be tricky, because that is the main time for thunderstorms.
SpaceX also deployed two fairing boats equipped with giant nets: Ms. GO Ms. Tree and Ms. GO Ms. Chief, hoping to seize Falcon 9’s Payload fairing When they return to earth. Weather will play an important role in the success of the catch. The half of the fairing is equipped with software that can navigate it to the recovery area, and a parachute system that allows it to gently slide back to Earth.
Attempts to capture the fairing have been cancelled since its launch on June 13, so SpaceX will try again today. So far, SpaceX has reflowed several sets of refurbished fairings, ultimately reducing the price of the rocket.
