No matter how much planning goes into space missions, one must always expect the unexpected. But luck favours the prepared. In July 2025, an unexpected visitor entered our Solar System, interstellar object 3I/ATLAS. ESA’s Jupiter Icy Moons Explorer – Juice – happened to be in the right place, with the right equipment, at the right time to see it. 

This unique vantage point offered a fleeting opportunity. What followed was a race against time. 

Genesis is the European Space Agency’s (ESA) navigation mission to measure Earth down to the millimetre. This precise measurement of Earth will have wide-ranging benefits, from satellite navigation to orbit determination to Earth science.

This video was published on social media by ESA astronaut Sophie Adenot with the following caption:

Day 035, orbit 0541 – Three cargo vehicles departing the Station in just three weeks… and since I recorded this video, we also waved goodbye to a Progress!

The Northrop Grumman Cygnus NG23 was named S.S. William “Willie” McCool in honor of the NASA astronaut and naval aviator test pilot who perished in the 2003 Space Shuttle Columbia accident. Following a U.S. Navy tradition, Jack – who shares the same professional background – rang the Station bell to mark the spacecraft’s departure.
