r/SpaceX Launch Weather Review

(15:10 UTC)

Weather-wise, so far everything looks pretty good, with showers, storms and cloud debris well away from the zone around the pad.

However, on days like these where the main threats are primarily diurnal convection which evolves quickly and unpredictably, we'll only really get a better idea within an hour or two from launch, at least beyond the 45th's mesoscale forecast and 70% GO.

(17:00 UTC)

With less than two hours to go until launch, the weather is still looking pretty good around the pad, better than yesterday so far, with showers and storm cells still keeping generally well clear of the 10 nmi/19 km zone around the pad, and like yesterday, cirrus blowoff from storm anvils to the west causing high-level cloudiness but seemingly well removed from their source such that they should not preculde launch.

(18:30 UTC)

Looks like there's just one modest cell that's the problem, that looks to pass directly over the pad. It should be on track to clear the area by the new scheduled launch time, but there are a few others downstream that may intrude on the party.

Spaceflight noob here, what's a range violation?

u/terrymr Jun 29 '21

Aircraft / boat in the hazard area.

Oh ok, makes sense, thanks a lot!

If I'm not mistaken, it means something was downrange of the launch (in the danger zone if you will). So they can't launch without endangering the trespasser. :( I say trespasser because planes/boats/whatever are told not to be in the area at launch time.

There's a couple mile no-go zone around the rocket including the airspace above. A range violation usually means someone or something that shouldn't be there entered the zone without authorization.

plane or boat or weather along the flight path of the rocket.

u/asoap Jun 29 '21

There is an area around the rocket where no one can be. For example air planes. So it's possible a plane or boat got to close to that zone.

It's when something intrudes the exclusion zone around the spacecraft or its flight path over the Atlantic. There is a radius around the launch site and a corridor down its flight path that no boats or planes can go through. It seems a plane flew through this exclusion zone

u/Narcil4 Jun 29 '21

the range is the airspace, so either someone was where they shouldn't have been or some failure from officials clearing the airspace.

u/Waiting4her Jun 29 '21

Airplane or a Boat in the area that it's not mean to be.

u/TbonerT Jun 29 '21

The area around the launch site has some condition that isn’t good for rocket launches. It can be any number of things, like wind, lightning, electrical fields, certain kinds of clouds that often have electrical fields or other hazardous phenomena, or a plane or boat has strayed into the keep out area.
