Seven members of the Mercury 13 are pictured in front of the space shuttle in 1995. From L to R: Gene Nora Jessen, Wally Funk, Jerrie Cobb, Jerrie Truhill, Sarah Rutley, Myrtle Cagle and Bernice Steadman
Funk was America’s first female Federal Aviation Administration inspector and it was her skills as a pilot that, in 1961, led her to become one of 13 women who passed secret medical tests to become an astronaut.
The Mercury 13, as they are now known, undertook the same tough mental and physical tests as the famous silver-suited Mercury 7.
Those latter all-American heroes included John Glenn and played an important part in the space race against the Soviet Union, eventually placing a man on the Moon.
The Mercury 7 tests, memorably detailed in Tom Wolfe’s book The Right Stuff (later a film), pushed the men to their physical limits. The doctor who devised them, William Randolph Lovelace, was also head of Nasa’s Special Committee on Bioastronautics.
This short time-lapse video shows the complete Bigelow Aerospace BEAM expansion from start to finish to its full expanded, pressurized volume on Saturday, May 28. BEAM was installed May 16 on the Tranquility module after being delivered aboard the SpaceX Dragon cargo craft.
In a big leap for the electrification of aviation, an Extra Aircraft aerobatic plane performed its first public flight with an electric powertrain. The video shows the flight of the aerobatic aircraft with an electric propulsion motor from Siemens that weighs 50kg and produces 260kW.

There are several resins types that can be used with composites. Generally, use the one that your aircraft kit manufacturer advises. Some examples are: vinyl-ester, polyester and epoxy resins. Epoxy being more expensive, will not react on most materials used in aircraft construction. But it might have a negative effect on your body, epoxies can be toxic.
Polyester resin dissolves some foam like materials as easily as warm water melts sugar. It hardens quickly when mixed when MEKP catalyst is added in the right amount by weight.
Vinyl-ester is a relatively newcomer and is mainly used because of the aggressive allergic problems some people experienced with the other epoxy resins.
The right choice of resin also depends on the application. If you are building fuel tanks then polyester resin might not be the best choice as it will slowly be dissolved by the alcohol in the fuel. Either use vinyl-ester resins, aluminum tanks or stay away from fuels with alcohol.
