Mission Launch Party

Saturday, April 18

Help us celebrate two historic flight missions – Artemis II, the first trip around the Moon since 1972, and Balloon Across the Atlantic, a world record balloon flight across the Atlantic Ocean.

All activities are included with general admission or membership.


Balloon Across the Atlantic

10 a.m.-12 p.m.

Bert Padelt and John Piper are career balloonists in Pennsylvania and New York. With two other pilots, Bert plans to fly a hydrogen-filled gas balloon across the Atlantic this May and achieve a world record for this size balloon. John and a team of meteorologists, balloonists, and colleagues on the ground will help inflate, launch, and give ongoing support and tracking for the flight.

Bert and John will be here at the Science Center for a meet and greet where visitors can ask questions, view memorabilia, and get an up-close look at a balloon gondola.

10:00AM – 10:30AM: Meet & Greet

10:30AM – 11:00AM: Presentation – Learn about sizes, shapes, and types of balloons, and building for a transatlantic flight

11:00AM – 12:00PM.: Meet & Greet

Artemis II – Back to the Moon

The 10-day mission that began with a spectacular launch on April 1 is the most important human spaceflight mission in a half century.  Four brave astronauts are on their way around the far side of the Moon – going farther than anyone has gone before.  They’ll splash down off the coast of California on April 10.

Along the way they will test equipment critical for establishing a sustained human presence on the Moon and Mars, monitor the effects of radiation and microgravity on their own health, capture high resolution images of the Moon, and deploy CubeSats for several international space agencies that will collect critical data in high Earth orbit about radiation and space weather.
