Spacesuit curator Cathleen Lewis explains Neil Armstrong's quote appears the way it does in the case of Neil Armstrong's spacesuit.

In part two of Walking on the Moon, we’re talking about the important science still happening with Apollo Moon rocks here on Earth a half-century later. 

As we approach the 50th anniversary of humankind’s first steps on the Moon, our ability to reflect on those events is thanks in part to how the moment was shared with people around the world. The Apollo 11 mission was not the first time television signals returned from the orbit of the Moon, but the landing in July 1969 was by far the most important to get just right.

Abraham Silverstein (1908-2001), created and named the Apollo program and, most critically, pushed the adoption of liquid hydrogen as a rocket fuel for the boosters that launched Apollo. 

Recent research conducted by the Lunar Reconnaisance Orbiter (LRO) team indicates that moonquakes on our Moon were caused by active lunar faults -- meaning that the Moon is currently tectonically active and that the moonquakes are a result of the shrinking Moon. 

The moment of humankind's first voyage to the Moon and back was captured in a series of photos taken by the Smithsonian Astrophysical Observing Station in Maui, Hawaii. They show the trans-lunar injection rocket burn which sent Apollo 8 hurtling out of Earth orbit toward the Moon on December 21, 1968–perhaps the only such images that exist.

In this episode, Emily, Matt, and Nick will unpack the often philosophical, sometimes spiritual reactions to viewing of Earth from above. 

December 21-27, 1968: the Apollo 8 crew of Frank Borman, James A. Lovell, Jr., and William A. Anders journeyed to the Moon, into lunar orbit, and back to Earth. 

AirSpace hosts give their take on First Man, the new biopic about the original Moon-walker Neil Armstrong. Spoiler – they land on the Moon.

The next few months will also bring some exciting developments in space science. There are new missions about to launch and spacecraft that will reach their destinations after long journeys. Here are six out-of-this-world things to look for in the news over the next few months.
