When places like NASA have job opening, you know there are overly-qualified candidates all walks of life. And that is just what happened last week when NASA posted a job description for its ”planetary protection officer”. But applicants with advanced degrees and ample experience, another rather young candidate stood out for his self-confidence and passion. His name is Jack Devis, he is nine years old, and he too sent in a sincere letter this job is perfectly suited to him.
