Sometimes one extraordinary view is all it takes to remind us how incredible spaceflight is, and how much we still have to explore. This morning’s “space jellyfish” gave people across the East Coast a reason to look up as @SpaceX launched science and supplies to the @Space_Station for @NASA. Hopefully it inspired a few to keep looking up!
These incredible photos from the ground and from space capture the launch of SpaceX CRS-35. Expedition 75 eagerly awaits its arrival, carrying important science to help further our ambitious goals of space exploration as well as critical hardware for extending the life of @Space_Station which will be used in future spacewalks.

There is so much packed into these photos. Unforgettable memories. Dragon has departed with Crew-12 and is on the way back to Earth after eight months. In front of Dragon is the antenna we installed together. These were both peak teamwork moments for @Space_Station and ground teams across @NASA and commercial operators.

Two walkouts, one station. 🛰️ @NASA's @SpaceX Crew‑12 and Crew‑13 both began their journeys waving to family and friends outside the Neil A. Armstrong Operations and Checkout Building at Kennedy Space Center. Today, both crews are living and working aboard the International @Space_Station as Crew‑12 prepares to wrap up their mission and return to Earth this week while Crew‑13 settles in for their long‑duration stay.
