TL;DR: The MAVEN spacecraft has eight science instruments (with nine sensors) that measure the energy and particle input from the Sun into the Mars upper atmosphere, the response of the upper atmosphere to that input, and the resulting escape of gas to space as mentioned in this paper.

Motion of the dipolarization front during a flow burst event observed by Cluster
Rumi Nakamura,Wolfgang Baumjohann,Berndt Klecker,Y. V. Bogdanova,André Balogh,H. Rème,Jean-Michel Bosqued,Iannis Dandouras,Jean-André Sauvaud,Karl-Heinz Glassmeier,L. M. Kistler,C. G. Mouikis,T. L. Zhang,H. U. Eichelberger,Andrei Runov +14 more
TL;DR: In this paper, a flow burst was associated with a clear dipolarization ahead of the high-speed part of the predominantly Earthward directed flow, and the authors found that a ∼2000 km thick dipolarisation front moves Earthward and dawnward with a speed of ∼77 km/s.
