It's amazing to think that something I saw just a few weeks ago is now in space. I got to see parts of the LISA Pathfinder satellite when I went to interview Martha Lenio about her simulated Mars mission. Now those parts have come together to fulfil LISA's mission to find evidence of gravitational waves.
Walking past the enormous rooms where engineers make all sorts of space-bound gadgets made me feel very small. Whatever else LISA achieves, the mission is certainly proof of their extraordinary work.
