Rosetta was a space probe built by the European Space Agency launched on 2 March 2004. Along with Philae, its lander module, Rosetta performed a detailed study of comet 67P/Churyumov–Gerasimenko (67P). During its journey to the comet, the spacecraft performed flybys of Earth, Mars, and the asteroids 21 Lutetia and 2867 Šteins. It was launched as the third cornerstone mission of the ESA’s Horizon 2000 programme, after SOHO / Cluster and XMM-Newton.

On 6 August 2014, the spacecraft reached the comet and performed a series of manoeuvers to eventually orbit the comet at distances of 30 to 10 kilometres (19 to 6 mi). On 12 November, its lander module Philae performed the first successful landing on a comet, though its battery power ran out two days later. Communications with Philae were briefly restored in June and July 2015, but due to diminishing solar power, Rosetta’s communications module with the lander was turned off on 27 July 2016. On 30 September 2016, the Rosetta spacecraft ended its mission by hard-landing on the comet in its Ma’at region.

The probe was named after the Rosetta Stone, a stele of Egyptian origin featuring a decree in three scripts. The lander was named after the Philae obelisk, which bears a bilingual Greek and Egyptian hieroglyphic inscription.

    1. English is not my first language.

    2. I think there are better things to waste brain capacity for.

      Trying to figure out what a person means from context instead of having the precisely correct words there takes more brain power, not less.

      It takes far more energy to read and think in imprecise language. That’s the whole point of precise language: you don’t have to work as hard to interpret it.

      But if you don’t mind speaking in broken English, no one can force you to learn.

        Dude, I would have even appreciated if you had simply told me where my title is wrong, because I do indeed prefer to speak and write proper English. Unfortunately you chose to be arrogant and pretentious about it. Maybe you should go back to reddit with that attitude, because most of us prefer a more friendly social intercourse around here.
