Through a series of space policy directives, the Trump Administration has called for a series of reforms to commercial space regulations, from launch to remote sensing. Jeff Foust reports that many in industry are finding that this regulatory streamlining isn't working out quite as they expected.
Long before "Deep Impact" and "Armageddon", an MIT class in the 1960s examined how it could deflect a threatening asteroid. Dwayne Day examines how the concept leveraged the Saturn V and other Apollo-era technologies.
One hundred years ago, astronomers observed a solar eclipse that provided them with evidence confirming Einstein's theory of general relativity. Jeff Foust reviews a book that examines the development of general relativity, and its effect on astrophysics in the century since that famous eclipse.
Last week NASA announced a new initiative to stimulate further commercial use of the International Space Station and separate commercial platforms in low Earth orbit. Jeff Foust reports on that effort and how it conjures up memories of a similar effort nearly two decades ago.
One of the major questions of the Apollo program is what role CIA intelligence on Soviet efforts played in decisions such as sending Apollo 8 to the Moon. Dwayne Day examines what insights the CIA offered NASA that could have shaped such decisions.
