According to EarthSky.org, “estimates indicate the tool bag should reenter the atmosphere between March and July of 2024”, at which point “it will disintegrate”.
Impulse for Model Rockets
Model rockets are classified according to the impulse that their motor can produce. In Canada, anyone over the age of 12 can have and use model rockets with a motor of up to 40 Newton-seconds. Anyone over the age of 18 have a limit of 80 Newton-seconds before the rocket is classified as a high-power rocket motor and is subject to more stringent regulations.
