"Musk dropped a surprise on Twitter. The workhorse spacecraft that will carry approximately 100 tons of cargo or 100 people to the surface of Mars, which until now has been popularly known as the Mars Colonial Transporter, can't be called that, Musk said. "Turns out MCT can go well beyond Mars, so will need a new name..." he tweeted on Friday evening. By Saturday evening he had a new name dubbing the spacecraft the "Interplanetary Transport System," or ITS."
"So far, Musk has only teased details of planned missions to Mars: both manned and unmanned. The first unmanned probe from SpaceX will be sent to the planet "as soon as 2018," it was said in June. Musk added that probes would be launched by SpaceX every two years, before humans are landed on the planet in 2025."
