Curiosity
NASA scientists sent Curiostiy to Mars in 2011. This was the first time we ever had something on Mars to try and investigate it! In 2014, it even found traces of water.
Augmented Reality
The idea of superimposing objects onto real-time pictures is something straight out of a 70s sci-fi movie. Now, it's a reality! Retailers like Amazon and Wayfair even have technology where you can "see" the piece of furniture in your room. Kinda crazy!
