This partnership between the ground and the crew has resulted in over 4,000 different scientific investigations and breakthroughs in a variety of fields! Here are some key milestones that we've hit along the way: 💻 More than 27,000 shifts have been operated by over 400 certified flight controllers to keep operations going continuously. 🔬 Payload facilities on orbit have been powered on for a collective total of over 2.6 million hours, providing essential resources for a wide variety of experiments. ⏰ In 2019 during Expedition 61, a record was set for the most science hours performed by the crew in a single week at 153 hours. 🥶 Cold Atom Lab achieved temperatures colder than space, reaching hundreds of nano Kelvin - mere fractions of a degree above absolute zero. 🌱 Astronauts have grown more than 50 species of plants on station, including tomatoes, bok choy, romaine lettuce, and chili peppers. 🧤 The Microgravity Science Glovebox has supported 72 different payloads with nearly 100,000 operational hours, and it was built for only 10,000. + so much more!
