NASA & GLOBE Connect People, Land, and Space

A group of elementary-aged students gather outside of Oldham County Public Library in La Grange, Kentucky, United States to look at clouds in the sky. “If anyone asks what you are doing, tell them, ‘I am a citizen scientist and I am helping NASA,’” Children’s Programming Librarian, Cheri Grinnell, tells the kids. Grinnell supports an […]

NASA’s Roman Observatory Passes Spate of Key Tests

NASA’s nearly complete Nancy Grace Roman Space Telescope has made another set of critical strides toward launch. This fall, the outer portion passed two tests — a shake test and an intense sound blast — to ensure its successful launch. The inner portion of the observatory underwent a major 65-day thermal vacuum test, showing that […]

NASA Crater Detection Challenge

Crater rims are vital landmarks for planetary science and navigation. Yet detecting them in real imagery is tough, with shadows, lighting shifts, and broken edges obscuring their shape. This project invites you to develop methods that can reliably fit ellipses to crater rims, helping advance future space exploration.
