On April 24, 1990, the space shuttle Discovery lifted off from Earth with the Hubble Space Telescope (HST) aboard. The following day:
… Hubble was released into space, ready to peer into the vast unknown. Since then, Hubble has reinvigorated and reshaped our perception of the cosmos and uncovered a universe where almost anything seems possible within the laws of physics.
The quote above is from a NASA website where the agency explains its plans to celebrate Hubble’s 25th anniversary. The celebration begins on April 20, 2015 and runs through April 26. There are a lot of activities, some of which you can view here. If nothing else, don’t miss this awesome Flickr page, where NASA has selected one wonderful HST image for each year the telescope has been in orbit. The images on this page are from there. Activities also include:
– Starting at midnight EDT on Monday, April 20, and running through Sunday, April 26, images taken by the Hubble Space Telescope will be broadcast several times each hour on the Toshiba Vision dual LED screens in Times Square, New York.
– The IMAX movie Hubble 3D is playing at select theatres across the United States throughout April. Hubble images come to vast, three-dimensional life, taking audiences through the telescope’s 25-year existence and putting them in orbit with astronauts during the latest servicing mission. Click here for more information and the trailer.
– Commemorative 3-D Hubble model and logo files will be available beginning April 20. The files can be downloaded and printed using a 3-D printer and assembled into a miniature Hubble model.
NASA Television will air the following anniversary events:
– Thursday, April 23 (9 to 9:45 a.m.) — Newseum, 555 Pennsylvania Ave. NW, Washington — NASA will unveil the official Hubble 25th anniversary image at this public event, with remarks by NASA Administrator Charlie Bolden, Associate Administrator for the Science Mission Directorate John Grunsfeld, Hubble Senior Project Scientist Jennifer Wiseman, and Space Telescope Science Institute Interim Director Kathryn Flanagan.
