Cluster reentry explained: world's first targeted reentry

The first of four satellites that make up ESA’s Cluster mission is coming safely back down to Earth, marking a brilliant end to this remarkable mission.
The satellite’s orbit was tweaked back in January to target a region as far as possible from populated regions. This ensures that any spacecraft parts that survive the reentry will fall over open ocean.
During 24 years in space, Cluster has sent back precious data on how the Sun interacts with Earth’s magnetic field, helping us better understand and forecast potentially dangerous space weather.
With this first ever targeted reentry, Cluster goes down in history
Q&A: Scientist discusses the MESSENGER mission to Mercury

Twenty years ago, the MESSENGER mission revolutionized our understanding of Mercury. We sat down with project head and former Carnegie Science director Sean Solomon to talk about how the mission came together and the groundbreaking work it enabled.
Q: As the principal investigator of the MESSENGER mission, what were your personal highlights or proudest moments throughout the mission's duration?
Sean Solomon: There were many personal highlights for me during the MESSENGER mission, beginning with our initial selection by NASA in 1999 and culminating in the publication by the MESSENGER science team of all of the findings from our mission in a book published nearly two decades later.
The most challenging events in any planetary orbiter mission are launch and orbit insertion. The successful completion of those two milestones for MESSENGER—in 2004 and 2011, respectively—were sources of great pride for me in the technical expertise of all of the engineers, mission design experts, and project managers who contributed to the mission.
The long flight portion of the mission provided multiple scientific highlights. MESSENGER's first flyby of Mercury in January 2008 yielded the first new spacecraft observations of Mercury in 33 years, and our team published 11 papers in a single issue of Science from those measurements six months later.
