I saw the movie #Apollo13 with #LunarModule Program Director #JoeGavin. Now it’s time to tell the forgotten story—which that film doesn’t show—of how he & his #Grumman #Team helped rescue the astronauts with a #LMLifeboat while the world watched: andrewerickson.com/2020/04/apollo… #Apollo50
Five decades ago, during the aborted #Apollo13 mission of April 1970, #Grumman Aerospace Corporation’s #LunarModule saved 3 astronauts by becoming a lifeboat-tugboat. Throughout the crisis, #LM Program Director #JoeGavin manned his post @NASA’s #MissionControl Center in #Houston.
Gavin led a multi-hundred-person team in Houston & Bethpage, NY to help coordinate assessment & use of the #LM’s capabilities for emergency #LunarLifeboat role.

Gavin, virtually all of his colleagues + contemporaries & #Grumman itself have subsequently departed from the scene.

This week is the 50th anniversary of the #Apollo11 #LunarLanding - 1 giant leap for mankind that helped us understand the #Moon and also gave us a better understanding of #Earth. We are posting some neat facts about the Moon this week!

A planet the size of #Mars crashed into Earth 4.5 billion years ago. The force was so great that it sent materials from #Earth and the planet flying into space. Some of this debris stuck together to make the #Moon. Earth's gravity held it in our orbit.

#Earth's surface is constantly changed by forces like plate tectonics and erosion so Earth's first rocks are lost to us. But we learn about Earth's early days by studying the moon since it's mostly static. #Apollo11 brought back 50 #moon rocks, some 3.7 billion years old.
