Why Space Cybersecurity Matters

Space systems are increasingly becoming critical infrastructure for our modern world:

Critical Infrastructure: Satellites support communications, navigation, weather forecasting, and Earth observation.
Growing Threat Surface: The space sector is experiencing rapid commercialization with thousands of new satellites being launched.

Increasing Attacks: Nation-states and other threat actors are increasingly targeting space assets.
Talent Gap: There's a critical shortage of cybersecurity professionals with space systems expertise.

By participating in this CTF, you're developing skills that are crucial for protecting the next frontier of cybersecurity challenges.
