A space probe named Philae has made history by landing on a comet.
Philae is the first spacecraft to ever achieve this the feat. The landing was on the comet 67P/Churyumov-Gerasimenko and it required immense precision, as even the slightest error could have resulted in cosmic calamity.
Wednesday’s landing capped a 6.4 billion-kilometer (4 billion-mile) journey that began ten years ago.
Rosetta, which was launched in 2004, had to slingshot three times around Earth and once around Mars before it could work up enough speed to chase down the comet.
It reached the comet in August and the two have been traveling together since then.
