The NASA Goddard Institute for Space Studies (GISS) offers a limited number of research internship opportunities throughout the year for high school, undergraduate, and graduate students. Typically, around twenty openings are available for summer interns, with about a dozen for autumn and spring terms. A significant portion of these summer internships are integrated into the year-round Climate Change Research Initiative (CCRI). The CCRI provides an interdisciplinary STEM engagement and experiential learning opportunity where students and faculty collaborate directly with NASA scientists on climate change research projects conducted at NASA GISS and partner institutions. Participants in these programs gain hands-on experience by working alongside graduate students and lead scientists, developing research questions, collecting and analyzing data, and contributing to scientific presentations, posters, and potentially publishable research papers. Eligibility generally requires applicants to be US citizens currently enrolled in a formal education program with a minimum 3.0 GPA. Depending on the project, interns may be required to reside within 50 miles of NASA/GISS in New York City or NASA/GSFC in Greenbelt, MD, though some projects may allow for virtual participation. All interested students must apply via the NASA STEM Gateway website. Deadlines for upcoming terms include May 16, 2025, for Autumn 2025; September 12, 2025, for Spring 2026; and February 27, 2026, for Summer 2026.
