From firstinspires https://www.firstinspires.org/community/inspire/2021-first-championship-update:
Dear FIRST® Community,
This season, we have explored new and exciting ways to deliver our programs with your safety and wellbeing as our top priority while ensuring all students can participate in meaningful ways. What has remained constant is our mission to inspire young people to be science and technology leaders and innovators. We are grateful to our entire community for their flexibility and patience as new information becomes available and we adapt to changing conditions.
Previously, we announced an extension of the FIRST® GAME CHANGERSSM powered by Star Wars: Force for Change season to provide additional time and flexibility for build seasons and local and remote events. As part of that extension, we hoped to move our season-culminating 2021 FIRST Championship events from April to a July/August timeframe.
These past few months, we have continued to evaluate the scale and viability of hosting 2021 FIRST Championship events that meet health, safety, and international travel guidelines. Due to conditions created by the ongoing pandemic, we are unable to host the events as planned and have made the decision to cancel the 2021 FIRST Championship events in Houston and Detroit. We share in your deep disappointment that we will not be gathering as a global community in person this season. However, the safety of our community is our overarching priority.
Fortunately, the FIRST GAME CHANGERS season continues. Around the world, many teams are still working diligently on their robots and projects as they prepare for judged FIRST activities. Additionally, we are still planning remote global celebrations to recognize the amazing accomplishments of FIRST teams this season, such as showcasing our teams’ innovative, real-world solutions on June 28-30, 2021, at the 2021 FIRST Global Innovation Awards powered by Star Wars: Force for Change. Stay tuned for details about additional season-culminating celebrations.
