Laser Interferometer Space Antenna (LISA)
We couldn't resist putting one science project in here that's still in the works. Get this: the LISA project aims to send three satellites to the Sun, where they will sit 3 million miles apart and shoot enormous lasers at each other to prove that gravitational waves exist (there's still no empirical proof they do, despite Einstein's theories!). How epic is that? But it gets better: if launched, LISA will beat out the Large Hadron Collider as the largest science experiment in operation. Funding has been a consistent problem, but the scientists behind the project hope to launch LISA by 2020. Keep your fingers crossed for these solar surfers!
