<h3>
<span class="mc1">About Space</span><span class="mc2">Track</span>
</h3>
<p>This site is an online satellite tracking system that allows you to view in real time positions of various space objects in Earth's orbit, such as the International Space Station (ISS), the Space Shuttle, GPS and Iridium satellite constellations, and over 5000 spacecraft and debris. You can also view visibility footprints and tracks of space objects predicted using data collected by NORAD and usually updated on a daily basis. The precision of satellite footprint and track calculation can be customized to your needs.<p>
<p>Many powerful and interesting features are planned; if you have your own ideas, please use the Feedback tab to submit them!</p>
