ЦитироватьSpaceX is targeting Sunday, March 2 for a Falcon 9 launch of 21 Starlink (https://www.starlink.com/) satellites, including 13 with Direct to Cell (https://direct.starlink.com/) capabilities, to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 9:24 p.m. ET, with backup opportunities available until 12:21 a.m. ET on Monday, March 3. If needed, additional launch opportunities are also available on Monday, March 3 starting at 10:04 p.m. ET.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX (https://twitter.com/SpaceX). You can also watch the webcast on the new X TV app.

This is the fifth flight for the first stage booster supporting this mission, which previously launched GOES-U, Maxar 3, and two Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean...

Falcon 9 launched 21 @Starlink satellites to orbit overnight. After stage separation, the first stage booster returned to Earth and landed on the Just Read the Instructions droneship, which was stationed in the Atlantic Ocean ~250 nautical miles off the coast of Florida.
 
Following the successful landing, an off-nominal fire in the aft end of the rocket damaged one of the booster's landing legs which resulted in it tipping over.

While disappointing to lose a rocket after a successful mission, the team will use the data to make Falcon even more reliable on ascent and landing.

by Jeff Foust March 8, 2025

WASHINGTON — A Falcon 9 booster that was destroyed after landing March 2 suffered a fuel leak during its flight that triggered a fire.

SpaceX officials speaking at two briefings March 7 about upcoming launches for NASA provided new details about the incident on the March 2 launch of a set of Starlink satellites, known by the company as Group 12-20, which caused the booster to topple after landing on a droneship.
...
The SPHEREx/PUNCH launch, now scheduled for 10:09 p.m. Eastern March 8, has been delayed more than a week primarily by launch vehicle issues. While SpaceX has not conducted a Falcon 9 launch since the failed landing, Scheiman said teams have been working on other issues with the vehicle for SPHEREx and PUNCH, including the payload adapter and fairing.
...
At another briefing a few hours later about the Crew-10 mission to the International Space Station, Bill Gerstenmaier, vice president of build and flight reliability at SpaceX, offered more details about the incident on the Group 12-20 launch.

He said there was a fuel leak starting about 85 seconds after liftoff in one of the nine engines in the booster. The fuel was vaporized by a hot portion the engine, creating a flammable environment. "But on the way up, there was on oxygen to interact with the fuel, so there was no problem at all during ascent."

He said that about 45 seconds after landing, "enough oxygen came into the compartment where it interacted with the fuel and a hot portion of the engine, which was known to be hot, and then we had a fire."

Falcon 9 booster lost after droneship landing
by Jeff Foust March 3, 2025
...
This was only the fifth flight of B1086, a modest number given that the current record for flights by a Falcon 9 booster is 26. The booster was originally built as a Falcon Heavy side booster and used on the June 2024 launch of the GOES-U weather satellite. It was then converted into a Falcon 9 booster, launching two Starlink missions and another carrying a pair of Maxar's WorldView Legion satellites before this mission.
