The world is counting on MIT to help meet the great challenges before us. You can help MIT by joining thousands of alumni and friends in the MIT 24-Hour Challenge on 3.11.21. In honor of this fifth year of #MIT24, our Challenge goal is to reach 5,000 donors that day. To help us reach our goal, more than 35 MIT departments and groups will be holding microchallenges. Your support will help our students, faculty, and staff stay the course in making a better world—now and in the better days ahead.
