What is a hybrid rocket motor? What advantages does it have over conventional liquid and solid propellant rocket motors? These questions point to an exciting breakthrough that occurred on December 13, 2018, when Virgin Galactic successfully launched VSS Unity on its first suborbital flight.
Much like medical triage, conservation triage analyzes the risk posed to an object and the hazards associated with not taking immediate action. Triage conservators ask questions such as: Can the object be handled safely by staff and researchers? Will the degradation of the object continue if it is not treated immediately? What treatment can we do, with the resources at hand, to keep this object stable as long as possible?
The Scene: A new wind tunnel, the NACA Full Scale Tunnel at the NACA Langley Memorial Aeronautical Laboratory, Hampton, Virginia The Time: May 27, 1931 The Action: A Navy Vought O3U-1 “Corsair II” –the whole airplane—is mounted in the wind tunnel.
In his memoir Moon Lander, Grumman project manager Thomas Kelly describes the exhilaration at Grumman for winning the contract to build what became the Lunar Module (LM), followed by trepidation when the design team realized the severe weight restraints they had to work under in order to get two astronauts safely to the lunar surface and back to lunar orbit. At the outset, Grumman and NASA worked with an initial estimate of 30,200 pounds, which was within the limits of the Saturn V’s booster capability; but this began to grow ominously as the work progressed.
With all the activities going on lately about World War II aircraft, I’d like to tell the story of Russian naval pilot Alexander de Seversky, that country’s top naval ace in World War I, who later became one of the most influential proponents of the use of strategic air power in warfare — and Disney film star — in the United States. De Seversky was born in Triflis, Russia on June 7, 1894, to an aristocratic family. He learned how to fly by age 14 from his father who owned one of the first airplanes in Russia. De Seversky earned a degree in aeronautical engineering from the Imperial Russian Naval Academy in 1914 — at the outbreak of World War I — and became a second lieutenant in the Imperial Naval Air Service the following year.
Purdue University, located in West Lafayette, Indiana, has a special place in the annals of space exploration, having among its graduates 23 (and counting) astronauts, including Gus Grissom, Neil Armstrong, and a host of shuttle crew members, who have flown on more than 40 shuttle missions.
Dr. Vance Marchbanks, Jr. is famous in both the black history and aerospace history communities for his accomplishments as one of the first in his field. He was one of two black MDs to complete the United States Army Air Corps School in Aerospace Medicine at the beginning of World War II. His fame continued through his association with the 99th and 301st Fighter Groups, who later became known as the Tuskegee Airmen.
Who do you call when you need to know everything there is to know about the Star Trek starship Enterprise? As the curator for that artifact—the original 11-foot model used in filming the Star Trek television program that aired from 1966 until 1969—I’ve spent a lot of time thinking and learning about Star Trek. The Museum has a lot of source material to rely upon: the acquisition, restoration, and exhibit record for this artifact stands at more than 1000 pages (and growing). In fact, I hired an intern two summers ago just to create a comprehensive index for that record so that I could know, for certain, whether I had checked every relevant document in it when searching for an answer. That review of the Museum’s records was a part of the move of the model that I have been planning for several years.
The world’s first ballistic missile campaign began when the first German V-2 missile successfully launched in combat hit a suburb outside Paris. A second launch later that day hit Chiswick near London. Senior curator Michael Neufeld discusses the V-2 and this campaign.
