Star Trek tech, in real life! 🖖 8 September is @startrek Day and while the series imagined futuristic gadgets, many are already flying in space with us. - Tricorder? On the @iss, astronauts use a handheld scanner to check how their muscles cope in microgravity. - Replicator? Our researchers are developing mini bioreactors to grow food in orbit — one day maybe even a space burger on demand. - PADDs? Astronauts rely on tablets for checklists and experiments. Paper manuals? Long gone. - VISOR? Augmented reality headsets now overlay digital instructions right into astronauts’ field of view. Which Star Trek tech do you wish you could test first? 📹 @europeanspaceagency 📸 @hubbleesa & @NASA, J.
