Christa McAuliffe Planetarium
Centennial High School
2525 Mountview Drive

The Christa McAuliffe Planetarium is located at Centennial High School in Pueblo, Colorado. The Planetarium has been in existence since the school was opened in 1974 and has seen several major renovations and upgrades to its seating and technology. The most recent renovation in 2008 - 2009 has resulted in new, interactive seating; a state of the art Bowen sound system, Christie DS2 projection system, and programming. The Christa McAuliffe Planetarium is one of only a handful of high schools in the United States that has the Evans & Sutherland Digistar 3 programming and Digital Theater system.

The Christa McAuliffe Planetarium has seating for 60 including two handicapped accessible seating areas. Access to the building is through the "main doors" located on the Mountview Drive side of the building. All other doors are locked to the outside.

The Rosetta Orbiter update 06-18-2015

 The Rosetta Orbiter continues its studies of comet 67-P/CG.

Philae Wakes Up!

 The first spacecraft to land on a comet has come back to life.  Philae, the washing machine sized lander of the Rosetta comet mission is in communication with its orbiter. 

To date, only spacecraft systems health messages are being transmitted.  However, the lander is receiving enough sunlight to recharge its batteries and warm up to an operating temperature.

Mission scientists are scrambling to assemble an exploration plan for the hardy machine, believed to be stuck in a crevice far from its original landing site. 

They say it will take several days to make the mission changes to both Philae and Rosetta to start science experiments.

Philae’s harpoon system for assuring it didn’t bounce failed to operate on landing and the craft bounced at least three times before lodging in a crevice.  

Lacking sunlight, the systems operated for 60 hours before the craft went into hibernation.  Scientists had hoped as the comet neared the Sun the stronger sunlight would give enough power for the systems to “wake up” as has happened.

While the actual location is not known, scientists think they will be able to pinpoint the landing site in a few days as the Rosetta orbiter is moved to a better orbit to receive Philae’s signals.  This is a requirement before any scientific study begins.

Originally Philae was expected to end its scientific work in March when its original landing site became too hot to continue. 

Now scientists say the lander may function far beyond the comets nearest approach to the Sun in August.  This would give scientists firsthand information on how a comet reacts to the Sun’s energy.
