As the vehicle passed over Vandenberg AFB, I went outside just as a lark and, sure enough there was some sort of visible venting event just as it passed the zenith around 9:18 PST!  A bright pinpoint of light expanded quickly to the size of a misty full moon then expanded into a diffuse cloud that passed right in front of a brightly shining Jupiter before dissipating completely after about 3 minutes. Great show and the first time I've seen a Centaur doing its thing.



Ah darn, wish I could have gone out and watched that myself.

And ULA, by working hard, once again makes space launch appear easy and routine.

Centaur continues to coast.

Chris, we have confirmation that the Magnetospheric MultiScale probe quartet has been successfully deployed into a highly elliptical orbit to study our magnetic field in the coming days.

Yeah, I know - I was watching..... ;D

This was a really hard mission to put together.

Another view of mission control.

Liftoff of MMS

Published on Mar 12, 2015
The Atlas V rocket lifts off from Space Launch Complex 41 at Cape Canaveral Air Force Station carrying four Magnetospheric Multiscale, or MMS, spacecraft on a mission to study magnetic reconnection. Scientists believe MMS will provide insights into the fundamental process that occurs throughout the universe. Liftoff was at 10:44 p.m. EDT.

It's out of shadow, almost due south straight up, cone shaped in binoculars. Awesome! Well worth getting out of bed for.

Yes about fourth mag. Naked eye, but binoculars and low power are better. Just destroyed my night vision, but happy.

Crude sketch, did not prep pencils and pad in advance. Grabbed what I could.

Edit: Sketch covers FOV viewed from an 8" dia. scope with a  2000mm fl and a 2" 40mm eyepeice. North down, East right, dot at cone tracked with cloud and is most likely Centaur.

Helodriver, excellent eyes!

I truly expected nothing, but the NASA-TV coverage showed that the ground track was going to come right overhead so I went outside. I was looking more southerly when the flash and outgassing happened nearly directly above. I wish I'd brought a camera out, it was a very visible event and would have photographed well. Watching the cloud diffuse and surround Jupiter was a cool bonus.

At this point it's all but a faint smudge in my C-8, but was well worth coming out for.

That makes me  being lucky enough to catch three Centaur fuel dumps, the other two being east coast NOSS launches.

Excellent job ULA!
