Education felt out of this world for schoolchildren when their questions were answered by astronauts on the International Space Station.
The off-planet field trip was thanks to a project organised by Professor David Alexander OBE.
The director of the Space Institute at Rice University in Houston, Texas, brought together teams from Houston, Scotland and Ecuador.
The project also involved communications company Connect, Scottish Enterprise, the University of Edinburgh and Guayaquil Space Society in Ecuador.
They worked with NASA, who opened a live link to the Station and played videos of the children putting questions to astronauts Kate Rubins and Shannon Walker.
Professor Alexander said: “We’re hoping this will be the start of something exciting, creating great relationships and inspiring students to pursue opportunities in the space sector.
“Talking live to the Space Station is a very rare event. We were so thrilled with the excitement it generated in the participating schools.”
The live hook-up was part of a free two-hour online watch party called Let’s Talk Space – Beaming schools from Scotland, Houston and Ecuador onto the Space Station.
A total of 1239 delegates signed up to listen to the astronauts as they answered questions. These ranged from how much does a space suit weigh to how much packaging is needed for food in space.
Attendees also had the opportunity to ask questions of a panel of space experts.
The event featured Bonnie Dunbar, one of only 65 women to go into space. She was joined by Serena Auňón-Chancellor, who has visited the Space Station twice.
The event also featured the First Minister of Scotland, Nicola Sturgeon, The Mayor of Houston, Sylvester Turner, and former President of Ecuador, Rosalia Arteaga.
It was chaired by broadcaster Kim McAllister and Dr Murray Collins, space lead at the University of Edinburgh.
“Bringing two more female astronauts to the party was a very rare treat. It’s just a great showcase of partnership working for the benefit of education.”
