Trojans

 A new study by the SETI Institute suggests two worlds will only rarely share the same orbit.

Of course, that happens in our neighborhood with planets and asteroids.  Those asteroids are called Trojans.

Mining

 Mining in space, if all goes well, will be a major driver of civilization at some point.

Currently, however, there are technological, legal, and economic hurdles to overcome.

Monkeys

 On this date in 1959, two monkeys survived a short spaceflight.

It was a crucial step toward human spaceflight.

Asteroid

 A mile-wide asteroid just flew past Earth.

Had it hit, it would have caused immense damage on a regional scale.

Energy

 A new study by physicists argues we need to quickly embrace nuclear energy and renewables or risk societal collapse.

If we do, the study predicts we could be a true interplanetary species within 200 years.

Interstellar Meteorte

 Avi Loeb and Amir Siraj of Harvard have determined that a meteorite that landed in Papua New Guinea in 2014 was an interstellar object.

It was also metallic, which is interesting.

Carpenter

 On this date in 1962, Scott Carpenter became the second American to orbit Earth/

It was his only space flight.
