In the early stages of today's countdown, ULA's team at the Atlas Spaceflight Operations Center a few miles from the Complex 41 launch pad have powered up the Atlas 5 rocket to begin testing the vehicle's guidance system.
The countdown just started for today’s Atlas 5 launch attempt at Cape Canaveral. Liftoff with the Space Force’s SBIRS GEO 5 satellilte is set for 1:31pm EDT (1731 GMT).
ULA says a bad temperature sensor caused yesterday’s launch scrub.

Minisforum's UM250 is a very small form factor PC with the power and the ports to take on a lot of tasks. And due to its choice of an older CPU, it's pretty cheap, too: sub-$500, even fully loaded. https://trib.al/WCMz08A https://twitter.com/arstechnica/status/1394331977600446479/photo/1

SCRUB. United Launch Alliance has declared a scrub for today’s Atlas 5 launch attempt after encountering a technical issue during fueling preparations.
ULA plans to try again tomorrow to launch the SBIRS GEO 5 military satellite.
New launch time! United Launch Alliance is now targeting liftoff of an Atlas 5 rocket from Cape Canaveral at 1:42pm EDT (1742 GMT).
This seven-minute delay was ordered to ensure the rocket does not get too close to another object already in orbit.
Members of United Launch Alliance’s team have authorized the loading of cryogenic liquid hydrogen and liquid oxygen propellants into the Atlas 5 rocket at Cape Canaveral.
Liftoff is set for 1:35pm EDT (1735 GMT) with the military’s SBIRS GEO 5 satellite.
The Atlas 5 countdown clock has resumed after a pre-planned 15-minute hold to verify all is ready to start filling the rocket with super-cold propellants.
Liftoff remains set for 1:35pm EDT (1735 GMT) with the SBIRS GEO 5 military satellite.

3C 397 is a fascinating supernova remnant that spans about 50 light years in width.
Its boxy shape was likely formed when heated remains of the exploded star crashed into the cooler gas in its surroundings
