space agency.

the countdown as engineers continue to evaluate a problem with engine 3, one of
the four RS-25 engines located at the base of the Space Launch System rocket's
core stage. According to the official NASA blog, engineers are considering
strategies to collect as much data as they can.

propellant into the engines and get them to the right temperature range for
starting, launch controllers condition the engines by applying more pressure to
the core stage tanks. Engineers are investigating why Engine 3 isn't being
adequately conditioned during the bleed procedure.

Teams are also examining what appears to be a crack in the
material of the thermal protection system on one of the flanges on the core
stage. The top and bottom of the intertank are fixed using flanges, which are
connecting joints that work like a seam on a garment and allow the two tanks to
be connected to it.
