Space is a big place, but our upper atmosphere isn't. Rapidly increasing numbers of satellites orbit there, in addition to innumerable bits of space debris, and rockets fly through it on missions to the moon, Mars, asteroids, and deep space. President Trump's newly revived National Space Council will have to manage this busy region and beyond. Ramin A. Skibba (@raminskibba) is an astrophysicist turned science writer and freelance journalist based in San Diego. The council members--which include heads of dozens of agencies, including the state, defense, commerce, transportation, and homeland security departments--have their work cut out for them as they develop recommendations for national space policy.
