So proud of this boy! He works hard & has really upped his commitment over this past couple of weeks on an exciting filming project!
#PlanetaryDefence means so much to him, its a blessing for him to be part of a great Space community who believes in him. Stay tuned

Near-Earth objects
& artificial space objects
pose a threat to infrastructure in orbit & on the ground.
So, communities accross the globe are working to enable the protection of people & infrastructure through detection, prediction & prevention technologies
