Pleiades National Planetarium Conference 2017

Oct. 10–14, 2017 | Saint Louis Science Center

Delegate Invitation Letter Sponsor Invitation Letter

The Saint Louis Science Center and the James S. McDonnell Planetarium is the conference site. For the first time in 47 years, seven regional organizations (GLPA, GPPA, MAPS, PPA, RMPA, SEPA, and SWAP) will come together for a national conference. Planetarium Manager Anna Green and her committee of regional representatives are planning a not-to-miss event.

The James S. McDonnell Planetarium features Boeing Space Station - two levels of exhibits illustrating the future of space travel. The Orthwein StarBay has several lab areas that give you a glimpse of what it's like to live and work on the International Space Station. The StarBay's most amazing feature is the central open area dominated by the Zeiss Planetarium Model IX which projects more than 9,000 stars onto a 24 meter dome creating a brilliant star field. Special features allow Planetarium staff to demonstrate eclipses, meteor showers and other celestial phenomena. The Planetarium’s lobby features a Mercury capsule and a Gemini capsule which were built in St. Louis!

Some conference events will also take place in the OMNIMAX® Theater. Massive, crystal clear images projected on the 5 story, 79 ft. diameter dome fill your entire field of vision, and combined with 14,400 watts of surround sound, create a truly immersive sight and sound experience.

Busses will be used to transfer the attendees between the conference site and hotel, so rental cars are not necessary (unless a delegate would like more freedom).

The conference host recommends flying Southwest Airlines as they are the most convenient by far. American, Delta, United and many others also fly into Saint Louis Lambert International Airport (STL). The hotel has a free shuttle between the airport and the hotel.

What to Pack

Climate: October in Saint Louis is beautiful with the changing leaves! The weather can be a bit unpredictable though (sometimes it’s still 80 degrees and sometimes it snows). Layers are advised and it is recommended attendees watch the weather for a week prior to arrival.

Banquet apparel: Some regions usually dress up while others do not. It is encouraged for delegates to follow their region’s tradition and/or do what makes them feel comfortable.
