Listen to lectures from some of the world's foremost experts in their field.
Confirming their attendance so far, listen to the thoughts of:

Dr. Linda Spilker, JPL and NASA

Dr. Linda Spilker is coming to us all the way from NASA and the Jet Propulsion Laboratory (California Institute of Technology). She currently holds the post of Project Scientist (Programme Manager) for the Cassini mission since 2010, and has been involved with Cassini since 1988. As recently as 2013, she was the recipient of the NASA Exceptional Service Medal.

Mark Bailey 

Professor Mark Bailey has been a staple at the Armagh Observatory, and the nearby Planetarium for many years. Having been a guest speaker with us back at COSMOS '99, he is no stranger to public outreach and lecturing in astronomy in Ireland.

Dr. Tom Spilker, JPL and NASA 

Dr. Tom Spilker is coming all the way from the Jet Propulsion Laboratory (JPL) and NASA. He is recently retired after 20 years at JPL, and now consults in both the science and engineering aspects of scientific space flight missions. He has worked on the Voyager, Cassini, Stardust, and Genesis missions, and currently is a science team co-investigator on the European Space Agency’s Rosetta mission. He also worked in “Mission Formulation,” or designing new science mission concepts. And he is married to our other guest speaker, Linda Spilker!

Damian Peach 

If you like your astrophotography, then Damian Peachis no stranger to what he has been able to achieve through the years. Stunning views of the Solar System, the night sky, deep sky, and more. He sells his own prints, which have also been reproduced in just about every astronomy publication around the world. He also hosts tutorials and classes in astrophotography around the UK.

Air-powered Rocket Launches

MAC member (and Engineer) Bob Campbell has constructed a pressurised air platform to act as a launch pad for up to 4 rockets! Building your rocket is easy: you just need an empty pop bottle (the 1.5 litre to 2.5 litre kind) and get creative!

The bottle neck is the 'exhaust', so your rocket has to be built upside-down.

This event will take place during the lunch break on Saturday afternoon from around 1:45pm and is open to all visitors to COSMOS, young and old.
