NASA Citizen Science
NASA's own list of research projects open to volunteers — hunting exoplanets, tracking clouds, classifying storms. Contributors have been credited on published papers.
- Natural Sciences
- Engineering
- Who can enter
- Anyone worldwide. Free; most projects need nothing but a browser, and several have named volunteers as co-authors
- What it costs
- Free. Some projects suggest equipment you may already own (a phone camera, a small telescope), and each project page says so up front.
- When it closes
- We could not confirm this year's date against the organiser's own page, so we are not showing a countdown for it. Last published: Open all year: pick a project and start, free.
Sending this to someone sends the four facts above, not just a name. They will see who can enter and what it costs before they decide.
