And then there were four.
Nora Al Matrooshi, the Arab world's first female astronaut, and Mohammed Al Mulla were confirmed as the UAE's newest astronauts in a landmark announcement on Saturday.
Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai, welcomed the pair to an elite club of Emiratis when revealing the news.
They join Hazza Al Mansouri, the first Emirati to journey into space, and Sultan Al Neyadi, who was part of the back-up crew for that momentous mission to the International Space Station in September, 2019.
