Wallops Island

Wallops Island is Virginia's designated Spaceport. It was named for John Wallop, a 17th-century surveyor who began patenting land on Virginia's eastern shore in the 1660's. In 1672 he received a Crown Patent of the 13-square-kilometer island from King Charles II, and in his will John Wallop referred to "my island formerly called Keeckotank." It was also known as Accocomoson or Occocomoson Island, but has borne the name "Wallops Island" for more than 260 years.

Little Joe II

The Little Joe II series of rockets did for Apollo what the Little Joe I did for Mercury*.

From Rockets of the World:

In order to make the flight to the moon, the Apollo spacecraft was launched atop a six million pound tank of explosive liquids called the Saturn V.

Little Joe 2 liftoff

Once again, a Launch Escape System (LES) was fitted to the nose of the capsule to move the astronauts out of harms way during the boost phase, and the Little Joe II program was designed to test the LES.

At it's most basic level, the Little Joe II consisted of a series of structural rings covered by commercially available sheets of corrugated aluminum. Four fixed fins provided guidance, with additional control surfaces added on later flights.

The first Little Joe II flight took place in August, 1963 at White Sands missile range in New Mexico.

On the final test flight, as the rocket ascended it was intentionally sent into a wicked tumble before the LES was activated. It performed flawlessly, proving the system would work under worst-case conditions.

In all, just five Little Joe II flights were made. Studies were made to extend the program to test the Apollo Lunar Module, but the idea never went beyond wind-tunnel testing (the Little Joe II/LM stack proved dynamically unstable). There was even a proposal for an orbital version.

There are some really nice photos here at the Field Guide to American Spacecraft.

If you'd like to build a flyable model rocket version of the Little Joe II, JimZ has the original Estes plans available for free online.

About the background picture (crossposted from the Skunkworks)

That's Dr. Robert Goddard, and the image came from NASA's GRIN (Great Images In Nasa) site, an amazing resource for historical photos about aerospace and space.

Each image is available for downloading in several sizes and resolutions, and also have additional information about the photos.

From the site description of this photo:

Dr. Robert H. Goddard at a blackboard at Clark University in Worcester, Massachusetts, in 1924. Goddard began teaching physics in 1914 at Clark and in 1923 was named the Director of the Physical Laboratory. In 1920 the Smithsonian Institution published his seminal paper A Method for Reaching Extreme Altitudes where he asserted that rockets could be used to send payloads to the Moon. Declaring the absurdity of rockets ever reaching the Moon, the press mocked Goddard and his paper, calling him "Moon Man." To avoid further scrutiny Goddard eventually moved to New Mexico where he could conduct his research in private. Dr. Goddard, died in 1945, but was probably as responsible for the dawning of the Space Age as the Wrights were for the beginning of the Air Age. Yet his work attracted little serious attention during his lifetime. However, when the United States began to prepare for the conquest of space in the 1950's, American rocket scientists began to recognize the debt owed to the New England professor. They discovered that it was virtually impossible to construct a rocket or launch a satellite without acknowledging the work of Dr. Goddard.

Check it out, tons of history and pictures.
