I was wondering when this would happen. The version 3 Starlink
satellites are each the size of a 737 when the solar wings are deployed.
Actually, that's not the case.
"the orbiting Gen 3 (V3) satellites weigh about 4,400 pounds
(2,000 to 2,500 kg) with an unfolded span of roughly 23 feet
(7 meters)."
Actually, that's just wrong, guessing you trusted AI?... Just don't!
The 7m size for the V3 satellites in the STOWED (launch) configuration,
IE before folding out the solar panels.
Don't think there's any "orbiting V3" satellites either, all the
operational ones are V1 and V2 minis and we're discussing the launch
of the first batch of operational V3 satellites (if all goes well).
IIRC Flight 13 did launch a few test "V3" payloads but those were in
the same suborbital trajectory as the F13 so is long dead and was
never intended for anything other than mechanical launch testing and
taking photos of the booster.
The weight does appear to be about right but that's about the only
thing it didn't get wrong.
The 737 wingspan ranges from 90 to 117 feet depending on model.
The figures I've found for the in-orbit footprint for a V3 satellite
is approximately 42m*18m, or 138*60 feet.
So it's not matching the wingspan/length but OTOH I think the area
(important for solar panels) is actually significantly larger than a
737's area.
So I don't think the 737 comparison[1] Musk actually made is
unreasonable. Some of the AI comparison I see OTOH feels a bit
exaggerated.
