Space History Today: Rockets, Retrieval, and that Moon Thing

Lots of interesting July 20th space history (even though I only concentrate on anniversaries in multiples of 5 years).

Forty-five years ago today, in 1964, the Space Electric Rocket Test (SERT-1) launched on a suborbital test flight from Wallops Island, Virginia. The vehicle tested electron bombardment ion engines. (I find this interesting because Area 1-14 at the Air Force Rocket Propulsion Lab [my first assignment in the USAF] tested electric propulsion concepts and, I believe, some ion engines. Ion thrusters are used for stationkeeping on many different spacecraft.)

And for terrestrial history with a connection to space, ten years ago today, in 1999, the Liberty Bell 7 spacecraft was pulled up from the bottom of the Atlantic Ocean, about ninety miles northeast of Great Abaco Island in the Bahamas. Astronaut Virgil I. “Gus” Grissom had flown in the Liberty Bell 7 on our country’s second manned spaceflight. (I find the retrieval particularly interesting, since my first project in the Titan System Program Office was to find and retrieve pieces of a failed Titan-IV rocket so the investigators could confirm the cause of the malfunction.)

That’s it, right?

Of course not. I’m actually pleased with the attention being paid to the 40th anniversary of the Apollo-11 landing, with dedicated sites like We Choose the Moon — and today is the day.

Forty years ago today, in 1969, the Lunar Module Eagle landed on the moon in the first manned lunar landing. Astronauts Neil Armstrong and Buzz Aldrin prepared to step out on the lunar surface, while Michael Collins orbited in the Command Module Columbia. A few hours later — at 10:56 p.m. Eastern Daylight Time, which was 2:56 a.m. Greenwich Mean (Universal) Time — Armstrong and Aldrin stepped onto the moon.

“One small step,” indeed.

I dream about the giant leaps.
