Цитата Falcon 9 Block 5 @Falcon9Block5 30 сComing up shortly, we should here a go or no go from the #SpaceX launch director for prop loading onto the #Falcon9 launch vehicle. One rule is currently being watched but the weather remains go as of this time.

The company's drone ship "Of Course I Still Love You" is parked roughly 400 miles (630 kilometers) northeast of Cape Canaveral.The Falcon 9's first stage booster will target a propulsive landing on the football field-sized drone ship at T+plus 8 minutes, 24 seconds.SpaceX's two fairing recovery ships -- named "Ms. Tree" and "Ms. Chief" -- are also in position in the Atlantic Ocean to retrieve the two halves of the Falcon 9's payload shroud around 45 minutes after launch.The vessels are equipped with giant nets to catch the fairing shells as they descend under parafoils.SpaceX has also retrieved the fairing structures from the ocean, but catching them in the nets prevents the shells from being drenched in salt water. That eases their refurbishment and reuse, SpaceX says.Today's mission will use the Falcon 9 first stage designated B1051. It will be the sixth flight of this reusable booster after launches with SpaceX's Crew Dragon spacecraft on an unpiloted test flight in March 2019, Canada's Radarsat Constellation Mission in June 2019, and three previous Starlink missions.SpaceX says both of the Falcon 9's two payload fairing halves have flown on two previous missions with Starlink satellites.

Цитата10/18/2020 14:56 Stephen ClarkFilling of the Falcon 9 rocket with super-chilled, densified kerosene and liquid oxygen is underway at Cape Canaveral. This will mark SpaceX's 17th launch of the year, and the 94th flight of a Falcon 9 rocket since June 2010.The liquid oxygen flowing into the first stage is chilled to near minus 340 degrees Fahrenheit (minus 206 degrees Celsius).Propellant loading begins with pumping RP-1 kerosene into both stages of the Falcon 9 rocket, and liquid oxygen into the first stage. Liquid oxygen begins loading into the second stage at T-minus 16 minutes.
