New York’s Times Square regularly fills up for great public events, the crowd chanting and cheering. Rarely, however, do they chant, “Science! Science! Science!” as they did last night. An extraordinary number of people came out at 1:31am to watch the landing of Curiosity, NASA’s new Mars rover.

The TED Blog decided it would be fun to watch live as Curiosity touched down, and indeed it was. The crowd of several hundred, braving a freak rainshower, watched expectantly for an hour before the landing, listening to a broadcast on NASA apps on their phones as the live feed from the control room played on a big screen above the square.

The landing of Curiosity has been long awaited — weeks of buildup, and of course many years of planning. (Watch the director of the Jet Propulsion Laboratory at NASA, Charles Elachi, describe the mission in 2008.) The people gathered were clearly excited, and indeed broke into small bursts of applause as successful middle stages of the complex descent procedure were completed.

And then, when the control room found out the landing was successful and erupted with cheers, the crowd joined in, and then began a second chant, “NASA! NASA! NASA!” — another first for Times Square.

Curiosity is, of course, one part of a long and rich tradition of exploring other planets. Below, some TEDTalks and TEDxTalks about Mars and the rest of the solar system.

Why go to Mars? In 2008, Charles Elachi, director of NASA’s Jet Propulsion Lab, asked that question at the Serious Play conference — and answered with great footage of early Mars rovers and “some of the fun things we’re doing on Mars“:

Closer to TED HQ, NASA will be showing footage from the landing on the big screen over New York’s Times Square. Some of us will be watching down there (pic below). Tweet to @TEDNews if you’re watching too.

Or follow along online. Head to mars.jpl.nasa.org for a livestream. IEEE Spectrum offers an updated timeline of events.

And of course Curiosity tweets.
