IRG announces Scholarship Program for rising college undergraduates, graduate students

The non-profit Interstellar Research Group (formerly the Tennessee Valley Interstellar Workshop) is proud to present its 2021 Scholarship Program, to provide two undergraduate scholarships and one graduate-student scholarship for qualifying students.

The $2,500 scholarships (including the Tim Bolgeo Memorial Scholarship), sponsored by IRG supporters Baen Books, Rob and Ruann Hampson, and Jay and Beth Roye, are merit-based, and require applicants to complete an essay with their application forms. The deadline for all applications is May 15, 2021.

Applicants for the undergraduate scholarships must be high school seniors or present undergraduates in the United States and its territories who plan to pursue their first undergraduate degree in a STEM-related field at any accredited, four-year American college or university. Applicants for the graduate scholarship must be full-time college or university students majoring in a STEM-related field, and seeking a graduate degree (e.g. MS, EngD, JD, non-exclusive) from an accredited college or university in the United States.

The Interstellar Research Group “was created to foster and assist the study, research and experimentation necessary to make human interstellar travel a reality, with untold benefits to life on Earth,” said IRG President Emeritus John Preston. “We can imagine no better way to demonstrate that goal than the creation of these scholarships, helping new generations of thinkers, builders and explorers to set their sights on the stars.”

For more information about the new scholarships, including application guidelines, visit:
