    The main benefit of the STEREO mission is that we have now several view points to look at the Sun and the solar wind. There are many things we can study better with two or more spacecraft than using just one spacecraft. STEREO provided at the first time three-dimensional images of the solar eruptions and coronal structures (same way as our two eyes give us three dimensional view of the world). The majority of the spacecraft (like SOHO and ACE) that have been observing the Sun are located between the Sun-Earth line (see the attached figure). For example, monitoring the coronal mass ejections (CMEs) that come towards the Earth is difficult at that point. When spacecraft are significantly away from the Sun-Earth line (like STEREO spacecraft in the attached figure) they can make more detailed observations of Earth-directed CMEs. This will improve significantly our ability to predict the disturbances that CMEs can cause in near-Earth space environment.

    Some of you have probably been to a movie theater recently to watch a 3D movie like "Avatar" or "How to Train Your Dragon." One of the other benefits of the STEREO mission is that we can now make 3D movies and images of the Sun, just like the 3D movies we see at the theater. The key to making a 3D movie or image is that you need 2 cameras, spaced a certain distance apart, to take photos or film the same scene at the same time. The STEREO mission consists of 2 spacecraft that can take images of our Sun simultaneously in order to create a 3D view. And of course, then you get to wear those really cool glasses! You can learn how to make your own 3D images here -
