Probably only visible in southern states, since it is a 28 point something inclination.
Not true. Around the time of the MMS separations they will be between 5000 and 6000 km, altitude, and will be visible from Canada all the way down to Peru. Visibility will improve even further at the time of the fuel dump when the objects are at even higher altitudes.

That is the answer I was looking for satwatcher. Thanks, now to try an stay up for the fuel dump!

Why, yes that is a pair of binoculars glued to my eyes...

Where might I find the location in the sky I should be watching for these events? Google is currently not being my friend. Thank you.

From the ground track in ULA's mission book ( http://www.ulalaunch.com/uploads/docs/Mission_Booklets/AV/av_mms_mob.pdf ) I would guess blowdown would be somewhere in the green circle. So, depending where you are, I would be looking high in the sky in that direction.

As a fun exercise Boston is ~2500km north of Cuba, and these events should be happening at 5000 km (ignoring the earths curvature) that is what, about 60ish degrees above the horizon, hand wave in the earths curvature and you are talking what, 45 degrees?

Watch for blow-down to start at T+2h 7m.

Atlas V Rolled to Launch Pad for MMS

Published on Mar 12, 2015
The United Launch Alliance Atlas V rocket is rolled from Vertical Integration Facility to the pad at Launch Complex 41. With four identical Magnetospheric Multiscale, or MMS, spacecraft, this is an unprecedented NASA mission to study magnetic reconnection. Scientists believe MMS will provide insights into the fundamental process that occurs throughout the universe.

Here's William Graham's extensive - as always - feature article!

http://www.nasaspaceflight.com/2015/03/ula-atlas-v-mms-launch/

That was a fantastic article William, and a fascinating read too!
I bet that took some time to articulate!

I love physics-related missions.

Go ULA!

ULA tiger team and NASA engineering polls were done just a minute ago and both are 'Go' for cryo tanking.
