The National Air and Space Museum unveiled POP today: the Public Observatory Project. Another celebration of the International Year of Astronomy, the historic 16-inch telescope set up in the observatory will be available for daytime use by the public. Craters on the moon, phases of the planets, and sunspots (with appropriate filtering and/or projection optics to protect Mark 1 Eyeballs from being burned out) are just some of the things the public can see there. If you can’t make it to the Smithsonian, you might want to visit Experience the Planets instead, and see the solar system through the eyes of artists. Or perhaps you would like to read a little about NASA’s Replicator, not quite ready for an order of Earl Grey, hot, but it can make parts for aircraft and spaceships at nearly the molecular level.
