A 5-day terrestrial competition during World Space Week (October 4-10, 2025) uniting participants worldwide in a space-themed athletic activity– knot tying.
Knot tying simulates conditions and skills needed for life in micro gravities, and also on earth. It’s the core exercise for the Space Games Federation’s Astrolete® training. And a baseline skill for our Space Athletics Playbook.
Participants must complete a series of knots while maintaining hands at chest level (simulating microgravity conditions) within a 60-second time limit– demonstrating the precision and endurance required for conducting space operations.
No travel is required. Challengers video themselves at a place of their choosing being timed while tying knots in proper form, submitting the resulting video to SGF.
Anyone and everyone is welcome to participate! Whether you’re a space enthusiast, knot-tyer, into sports, gaming, puzzles or crafts–or just enjoy a challenge—we’re excited to see how you do.
Our team of space, sports and entertainment experts celebrates space. We’re committed to building a global community through events and supporting STEM edutainment. We don’t talk about it much, we just do it.
