In COSI's Teen Tech Studio, teens often ask about the cost of 3D printers. And the answer is that it depends on a lot of factors...how big of a print area do you want? Print quality? Type of filament? DIY kit? Etc.
Congratulations to the European Space Agency on their Rosetta Mission and their lander, Philae, reaching the surface! For the first time in human history, a spacecraft has landed on a comet. This is an incredible feat - Comet 67P/Churyumov-Gerasimenko is moving more than forty times faster than a speeding bullet, is spinning, has a rough and rocky surface, and is ejecting gases. The European Space Agency launched Rosetta in 2004, so today is the culmination of 10 years of traveling through space for this one moment.
Here's an image taken from Philae as it approached the landing site earlier today.
Here's a rare "behind the screen" shot of our Planetarium from above. We're looking through the tiny holes in the dome to the theater below, as we prepare for our reopening on November 22. We have been installing shows, rehearsing our live performances, and cleaning to get ready for the big day.
We've got our first star! Our new Planetarium sign is getting installed. For those who can "sneak peek" a look at the queue area when they are riding the High Wire Unicycle, they may also see our backlit images of beautiful galaxies and nebulae.
