The Rosetta spacecraft has just scored another historic first by making the closest flyby of the comet 67P/Churyumov–Gerasimenko it has been following and studying since last August.

The probe passed mere 6 kilometers (3.7 miles) from the surface of the ice ball in a unique display of affection on the Valentine’s Day. Taking into account the scale of the universe, it might well be considered a kiss on the cheek.

In November, Rosetta sent a smaller probe, Philae, to the surface of the comet. The unprecedented landing resulted in volumes of priceless data transmitted back to Earth, but the probe landed in shadow and had to go into hibernation mode after its batteries ran out. Rosetta has not been able to find the probe on the comet’s surface.

However, the February 14 mission was not about locating Philae. The daredevil flyby was supposed to let researchers sample the comet’s atmosphere and take high resolution shadow-free pictures of the enigmatic celestial body. The European Space Agency (ESA) promised to publish the images later this month.

Interestingly, Rosetta will never be able to get this close to the comet again. For the remainder of the year, the spacecraft will make numerous flybys at a distance ranging from 15 kilometers (9.3 miles) to 100 kilometers (62 miles), according to ESA.

Rosetta, launched in 2004, is on a mission to study 67P/Churyumov–Gerasimenko in order to determine whether comets brought water and simple organic molecules to Earth billions of years ago, paving the way for life.
