SpaceX is scheduled to attempt a Falcon 9 launch carrying 21 United States military Space Development Agency data satellites early Saturday. [^1]

The prior attempt on Monday October 5 was halted by an automatic abort at T minus 58 seconds, moments after onboard computers assumed control of the countdown. [^4] SpaceX has confirmed the rocket and payload remain in good health, with teams resetting for the new window. [^6]

On October 9, NASA deployed the KREPE-3 heat shield experiment aboard the Northrop Grumman 24th Cygnus cargo mission prior to the craft's undocking from the International Space Station. [^2]

The Cygnus XL was released from the station's Canadarm2 robotic arm at 12:44 p.m. EDT that day. It had been docked at the station for nearly six months. [^3] [^7] This is the third flight in the KREPE series, which uses departing cargo craft to test heat shield technology without dedicated launch missions. [^5]
