In celebration of World Space Week, the Union County Board of County Commissioners invites residents to visit Trailside Nature and Science Center in Mountainside for an engaging Space Day adventure, featuring a variety of special programs, crafts, and activities designed for children ages six and older. The event will take place on Saturday, October 4th, from 11:00 a.m. to 3:00 p.m.
“Fall is a wonderful time to get outside and enjoy the changing seasons with family and friends. Trailside’s special Space Day programming will be a day that is out of this world, and filled with extraordinary activities that the whole family will love,” said Commissioner Chairwoman Lourdes M. Leon. “I encourage everyone who enjoys having fun and learning about the wonders of the universe to visit Trailside during this event.”
The Space Day programming will include:
11:00 A.M. – Space Explorer Laser Light Show – Experience dazzling laser animations set to popular music, exploring the structure of the solar system and the ways lasers enhance our understanding of the universe. All participants will receive a glow bracelet before the show.
12:00 P.M. to 2:00 P.M. – Solar Viewing – weather permitting, visitors will have the opportunity to join members of the Amateur Astronomers, Inc. for a special solar viewing in front of the Trailside Visitor Center.
1:30 P.M. – Life on the Space Station – Speaker Paul Cirillo will lead this engaging discussion about outer space, showcasing the latest astronomical images from observatories both on and off the Earth. Paul is a member of the NJ Astronomical Association, which operates the largest public observatory in New Jersey. He is also a volunteer outreach “ambassador” for NASA’s Jet Propulsion Laboratory. His easy style of communication allows a diverse audience to better understand the wonders of the universe.
2:30 P.M. – Guided Walk on the Solar System Trail – Participants will embark on a half-mile walk, where each step represents a million miles in space, and enhance their understanding of our solar system using audio guides.
Guests are welcome to visit the front lobby for free crafts and giveaways with a space theme. A modest fee will apply to some programs, and pre-registration is required. To register or for more information, please visit ucnj.org/trailside.
