Does this job sound like it might be for you? “Planetary Protection Officer, NASA.” The job opening was announced by the United States space agency, NASA. The Washington Post called the job title “one of the greatest ever conceived.” If you think this job seems just right for action movie stars like Bruce Willis in “Armageddon” or Will Smith in “Men in Black” or “Independence Day,” you are not alone. The announcement says the job pays up to $187,000 yearly. It is getting a lot of attention on social media this week. One person wondered if the job comes with a cape like a superhero would wear. But before you start practicing your fighting skills, take a closer look at the description of the job. Planetary protection is concerned with the avoidance of biological contamination in human and robotic space exploration. This means the person who gets this job will be in charge of making sure Earth organisms are not accidentally taken to other planets.
