School Holidays: Operation: Plants in Space (ages 7-14)

Between Saturday 14 December 2024 and Saturday 25 January 2025
As humans continue to explore space and go on longer missions, to the Moon and further to Mars, plants will come along with us. Astronauts have been nurturing space gardens on the International Space Station for decades, but we are still finding the best ways to grow plants in space. Plants in space are used for food and research, but they are also playing an important role for astronauts’ well-being and foster a connection to Earth. What do we need for plants to thrive off-Earth? How can we produce enough food for the astronauts in this new environment and encourage sustainability? Due to limited spaces, please only book tickets for participants. Adult caregivers will be counted separately at the door.

There are thousands of satellites in space, but only two regularly have a human crew on board. So how do the rest of them function? Join Hannah to discover what mission operations actually looks like, both with respect to the whole mission and day-to-day level. Because you can't just throw a computer into space and expect to talk to it, they will discuss why you need to operate spacecraft in space, how to make sure you can actually control them, and some of the challenges you might encounter in doing so. Then, to give any potential future spacecraft operators an idea of what their future potentially holds, Hannah will talk a little about what the day in the life of a mission operations engineer looks like and how they got to where they are today.
