It means you have a very, very good chance of seeing the northern lights. This is the strongest storm of the current solar cycle.

yes and, as usual, it's cloudy here  :(

They say it might be visible down to northern California!

Oh well, I'm sure these spacecraft will get a good workout in their lifetime.

Wow. Good to know. If there was a G4 storm at any time, I bet THEMIS could see the northern lights from its current position.

Trying to find where this was stated "the 20th consecutive Atlas mission to fuel-and-launch on a single countdown attempt."

Have you tried asking Justin for his sources??

Trying to find where this was stated "the 20th consecutive Atlas mission to fuel-and-launch on a single countdown attempt."

Not sure if this was stated here on NSF. But that was exactly what I remembered from the 3rd X-37B launch in December 2012 (one can check all the threads here for confirmation).

Anyway it took some luck for the Atlas to do so - the DIV hit weather problems for the last 3 times and Atlas just got lucky that on those days they were able to fly before the end of the window.  ;)

Space Communications Networks Support MMS

Published on Mar 18, 2015
All three of NASAís Space Communications Networks are excited to support the Magnetospheric Multiscale (MMS) Mission in its journey to study the microphysics of magnetic reconnection. The Near Earth, Space and Deep Space Networks will support MMS through it commissioning phase and eventual science mission.

Today's mission update now online! http://1.usa.gov/1FFCTAk

--All spacecraft subsystems continue to perform as intended and the Navigator GPS performance is nominal.

--Observatory attitude control and maneuver performance are nominal.

--No significant issues with the Instrument Suite. Fields suite activations continue.

--All MMS observatories have been spun back up to 3 revolutions/minute after completing mag boom deployments. The Spin-plane Double Probe and Axial Double Probe booms are still stowed.

--The Electron Drift Instrument was activated and the Gun Detector Unit turned on with low voltage on all observatories. EDI flight software and data table loads have commenced on all observatories.

MMS Spacecraft Transition to Tetrahedral Flying Formation

Published on Jul 29, 2015
In the latter half of July 2015, the four satellites of the Magnetosphere Multi-scale (MMS) mission move into their tetrahedral formation flying configuration as part of the checkout for the science phase of the mission.

Rippled Quasiperpendicular Shock Observed by the Magnetospheric Multiscale Spacecraft

Quote
Collisionless shock nonstationarity arising from microscale physics influences shock structure and particle acceleration mechanisms. Nonstationarity has been difficult to quantify due to the small spatial and temporal scales. We use the closely spaced (subgyroscale), high-time-resolution measurements from one rapid crossing of Earthís quasiperpendicular bow shock by the Magnetospheric Multiscale (MMS) spacecraft to compare competing nonstationarity processes. Using MMSís high-cadence kinetic plasma measurements, we show that the shock exhibits nonstationarity in the form of ripples.
