A SpaceX Falcon 9 rocket was scheduled to launch the Crew-6 mission to the International Space Station (ISS) for NASA early Monday morning (Feb. 27) from Kennedy Space Center in Florida. But the launch team called the effort off less than 2.5 minutes before T-0, citing a ground-system issue.
"Teams were tracking a ground issue with TEA-TEB — that's the ignition fluid that actually sparks with the oxidizer and allows the engines to fire," NASA commentator Gary Jordan said during the agency's webcast of Monday's launch attempt.
That issue could not resolved in time ahead of the instantanteous launch window at 1:45 a.m. EST (0645 GMT), leading to Monday morning's scrub. The next launch opportunity comes on Thursday (March 2) at 12:34 a.m. EST (0534 GMT); weather on Tuesday (Feb. 28), the first possible opportunity before that, is not favorable for launch, according to NASA and SpaceX.
Crew-6 will send NASA astronauts Stephen Bowen and Woody Hoburg, the United Arab Emirates' (UAE) Sultan Al Neyadi and Russian cosmonaut Andrey Fedyaev toward the ISS aboard the Dragon capsule Endeavour.

Is this problem the result of a poor electrical ground? The story has a wording problem that makes me think a simple ground rod was installed improperly.
Good. Safety First.
I know how they feel! I can never get my charcoal lit either. :-(
The SpaceX Falcon 9 was successfully launched this afternoon around 6 from KSC
I think that they are saying that it was a GroundBased System that has to do with the Ignition of the fuel mix as it comes out of the exhaust cones. The system would be equal to a stick lighter being used to light a gas BBQ Grille that the spark ignition didn’t work.

Because You’re not using enough gasoline.🤪
Folks, it was launched yesterday afternoon….
….I not only got notice of it locally….I watched it happen
It was perfectly beautiful!
No that was a unmanned that was launched.The payload was a batch of Starlink Satellites.

While they are at it they should change out the headlight fluid, too!
rocket man...
I stand corrected, thanks
Welcome, no problem. You’re ok to sit corrected if You like 🤪
SpaceX launched the first batch of next-generation Starlink internet satellites Monday from Cape Canaveral, deploying 21 bigger, heavier, more capable spacecraft to boost capacity for the global broadband network.
A Falcon 9 rocket hauled the 21 Starlink satellites into a 230-mile-high (370-kilometer) orbit after lifting off from pad 40 at Cape Canaveral Space Force Station at 6:13:50 p.m. EST (2313:50 GMT) Monday.
SpaceX delayed the launch from earlier Monday afternoon to wait for radiation levels to abate following a solar storm that sparked dramatic auroral displays visible across Northern Europe and Canada.
The new Starlink satellite design debuted on Monday’s launch, called “V2 Mini,” have four times the communications capacity of earlier generations of Starlink satellites, known as Version 1.5, SpaceX said.
The upgraded Starlink V2 Mini satellites are an intermediate step between SpaceX’s original Starlink satellite design, and an even larger spacecraft platform SpaceX plans to deploy using its new-generation Starship rocket. The Starship has nearly 10 times the payload lift capability of a Falcon 9 rocket, with greater volume for satellites, too.
SpaceX could attempt to launch the huge Starship rocket into space for the first time as soon next month from South Texas. But the program has faced developmental delays, and SpaceX decided to build miniature versions of the upgraded Starship-compatible Version 2 Starlink satellites to fly on Falcon 9 rockets.
“The V2 satellites launched on Falcon 9 are a bit smaller, so we affectionately refer to them as ‘V2 Mini’ satellites,” SpaceX said. “But don’t let the name fool you, a V2 Mini satellite has four times the capacity for serving users compared to its earlier counterparts.”
The Starlink V2 satellites will be capable of transmitting signals directly to cell phones, a step forward in connectivity from space that other companies are also pursuing. The V2 Mini satellites have more powerful phased array antennas than older Starlink satellites, and introduce E-band for backhaul links with gateway stations.
“This means Starlink can provide more bandwidth with increased reliability and connect millions of more people around the world with high-speed internet,” SpaceX said.(Excerpt, continued at Link plus videos)

Falcon 9/Merlin engine ignition is by the chemical reaction of “TEA-TEB”, not by “electrical spark”. TEA-TEB ignites upon exposure to air/oxygen. Also used on the Saturn 5 F-1 engines and the SR-71:

Thank you. I am looking forward to the launch.
Oh I much prefer sitting!!!:)……I really did get a notice that it was a ‘go’…..and actually saw a beautiful vision in the sky……so assumed that was it
Ok, put away the crack pipe🤪😁
No big deal.
Looks 👀 like another try early Thursday AM:

Had a notice that it went!
Am I right this time?
