SpaceX Falcon9 Launch from Vandenberg Visible from Northern California

Even though it's 300 air miles from my house to the launch pad at Vandenberg, I knew it would be quite visible - first, because in the pre-dawn twilight, the exhaust plume would be illuminated by the sun; and second, to be visible above the horizon at that distance you only need to be 18.5 km in the air, which an orbital rocket covers in a short period on the order of a minute. Sure enough at 6:18 Pacific Time I saw it. In the pictures below you can quite clearly see that the first stage has burned out and the second stage has ignited.





I was amazed at how quickly it appeared to be moving especially at this distance, but I didn't take video. Fortunately, Reddit user tKMagus did, from a plane as they were landing at LAX (about a hundred air miles, 3x closer):

San Diego from Space, By Balloon

High altitude balloon launches are cool, especially when you can clearly see the San Diego coastline. It always amazes me that in the distance you can drive in a half hour, you're in space. (Now where's my check from the Round Earth Conspiracy! Come on guys!)

That Wasn't a Missile You Schmendricks

(If you heard about the supposed rocket seen off the California coast the other evening, you'll know what I'm talking about - otherwise don't waste your time.)

It was pretty unambiguously the contrail of an airplane, seen head-on. How do we know this?

1) If it were a rocket, it would have had to be the slowest rocket ever. Even from twenty miles away the launch at Vandenberg that I saw recently positively hauled ass into the sky.

2) People north and south on the coast from the sighting area didn't report seeing anything strange. Why? Because to them the same cloud would have looked like a normal contrail.

3) There were likely boats (fishing and otherise) closer to it, maybe even under it. Granted, we don't know if any vessels were in the vicinity. However, the fact that there were no reports from any boats (who might even have heard it if it was a rocket - rockets are loud) is another point off the missile hypothesis.

4) Similar things have happened before, and they were contrails also. (See the link at the end of this post.)

5) Yes, it glowed even after sunset. No kidding! That doesn't mean the cloud was burning rocket exhaust, it just means it was high up, just after sunset. When you're significantly off the surface of the Earth, you get sunlight after sunset. This is true even at the summits of tall, steep mountains. Ever heard of alpenglow?


Needless to say, "Cloud Not From Missile" isn't a good story, so it's not national news. If you still don't believe me, read this pilot's blog. He's even predicted exactly which flight it is, and a) invited the press to film it at the same time, from the same location, with the same weather conditions, and b) asked the chemtrails/conspiracy nuts to give him other evidence. Just a guess - the fact that people notice it this week might have to do with daylight savings.

So calm down dummies.

Finally Saw a Space Launch

A spy satellite on top of a Minotaur vehicle, launched last night from Vandenberg AFB, exactly at the start of the launch window. (What's interesting about this satellite is it's apparently the first one designed to spy on other satellites.) I watched from Refugio Road just southeast of the tunnels near Gaviota, which is ~25 air miles from the launch site. From that distance the vehicle was not obvious but the stage separations were quite clear (I think you can kind of see one in the time lapse photo below as a slight bulge and then narrowing near the top of the arc as it tilted west out over the Pacific). A low crackling rumble became audible just about 2 minutes after the launch (from 25 miles!); much more suspenseful waiting for that than counting seconds between lightning and thunder.

I've been wanting to see a launch for years. Finally!
