If you’ve ever spent a birthday alone quietly singing to yourself, congratulations, you have more in common with the Mars rover than you may have thought!

Saturday marks five years since NASA’s Curiosity rover landed on Mars to begin its mission of conducting research into the Red Planet. And while it’s technically an anniversary, the engineers at the space agency programmed their cute little robot to sing the “Happy Birthday” song.

And the results are, uh... a little depressing.

The reports of my singing are greatly exaggerated. I only hummed "Happy Birthday" to myself once, back in 2013. 🎂🎵 https://t.co/wK3HGP2STY pic.twitter.com/o4b3AuVm1c — Curiosity Rover (@MarsCuriosity) August 4, 2017

NASA said that the rover has actually only hummed the song once before on its birthday in 2013, which is somehow even more sad.

Despite being all alone, Curiosity has a great deal to celebrate.

Thanks to the rover, we’ve gotten some magnificent photos of Mars never seen before. The NASA rover has also found methane and organic chemicals on the planet ― which could indicate that there was once life on Mars.

The rover is likely to die alone on the planet.

Anyway, happy birthday!
