In 1934, Joseph Dunlap Mountain, a thirty-two year old former Army Air Service pilot, signed on with the California-Arabian Standard Oil Company (CASOC, now Saudi Aramco) to serve as a pilot, aerial photographer and mechanic on the company’s 1934-’35 survey expedition to the Kingdom of Saudi Arabia.

The remarkable twin Voyager spacecraft continue to explore the outer reaches of the solar system decades after they completed their surveys of the Outer Planets. 

This piece is a follow up to the posts below, in which I describe my experience flying a PT-13 Stearman that was used to train Tuskegee Airmen during WWII, from Moton Field, Alabama to Andrews AFB.

  October is American Archives Month—a time to celebrate the importance of archives across the country. In honor of Archives Month, we’re participating in a pan-Smithsonian blogathon throughout the month. We, and other bloggers from across the Smithsonian, will be blogging about our archival collections, issues, and behind-the-scenes projects. We encourage you to check out the posts on all of the participating blogs, as well as related events and resources. You may have heard that the National Air and Space Museum Archives is moving.  The collections and offices are moving from the current location of Building 12 at the Paul E. Garber Restoration and Storage Facility and from the Museum in Washington, D.C. to their new location at the Steven F. Udvar Hazy Center

The universe is about 13.7 billion years old and has expanded since its beginning at the Big Bang. Because distant objects appear to be receding as the universe expands, the light from them is “stretched” out, altering its wavelength to the red part of the electromagnetic spectrum. This “redshift” can be measured for every object in deep space.

I had my first glimpse of the end of the shuttle era in April, three months before Atlantis touched down from the final shuttle mission. Discovery had just completed its last flight, and I had an opportunity to visit Orbiter Processing Facility (OPF) Bay 3, which for years had been Discovery’s home for between-mission servicing. Discovery did not return to Bay 3 after STS-133, moving instead into Bay 1 for post-flight work.
