Space for Equality: NASA Joins the It Gets Better Project

By:

“It’s becoming the new normal — you’re being defined by your character and not by whom you love.”

When we lost pioneering astronaut Sally Ride in 2012, many knew that as she boarded the Space Shuttle Challenger in June of 1983, she became the first American woman in space and the nation’s youngest astronaut to ever launch into the cosmos. But few were aware that she was also America’s first lesbian astronaut in space — a quiet but powerful rebel of gender diversity on multiple levels in a field still dominated by rigid stereotypes and gender norms. At the time of her death, Ride had been with her partner, Tam O’Shaughnessy, for the past 27 years. And yet one can only imagine the pressures, both inward and outward, she had to withstand coming of age at a time of extreme orientation-based discrimination.

Hardly any movement has done more to alleviate the spectrum from crippling self-doubt to suicide that young queer people struggle with than the It Gets Better project, masterminded by Dan Savage and his husband of 18 years, Terry Miller. Since its conception in 2010, it has drawn thousands of brave people of various sexual orientations and gender identities, as well as a cohort of heterosexual supporters — from countless individuals to the staffers of organizations like Google, Apple and Etsy to the cast of popular TV shows like House and True Blood to President Obama himself — to face the camera and help struggling LGBTQ youth face themselves with dignity and inner peace. Thirty years after Ride boarded the Challenger, NASA joins the It Gets Better ranks with a heartening testament to the diversity of the LBGTQ community, with space agency staffers ranging from interns to managers, engineers to astronauts, and even NASA’s Chief of Staff.

It almost doesn’t matter anymore — it’s who I am; it’s one part of who I am and not everything that I am.

Complement with Dan Savage’s recently released and excellent American Savage: Insights, Slights, and Fights on Faith, Sex, Love, and Politics, discussed in brief here.

Gorgeous Black-and-White Photos of Vintage NASA Facilities

By:

From the wind tunnels the made commercial aviation possible to the analog machines that preceded the computer, a visual history of the spirit of innovation presently unworthy of the government’s dollar.

Among the great joys of spending countless hours rummaging through archives is the occasional serendipitous discovery of something absolutely wonderful: Case in point, these gorgeous black-and-white photographs of vintage NASA (and NASA predecessor NACA) facilities, which I found semi-accidentally in NASA’s public domain image archive. Taken between the 1920s and 1950s, when the golden age of space travel was still a beautiful dream, decades before the peak of the Space Race, and more than half a century before the future of space exploration had sunk to the bottom of the governmental priorities barrel, these images exude the stark poeticism of Berenice Abbott’s science photographs and remind us, as Isaac Asimov did, of NASA’s enormous value right here on Earth.

NACA's first wind tunnel, located at Langley Field in Hampton, VA, was an open-circuit wind tunnel completed in 1920. Essentially a replica of the ten-year-old tunnel at the British National Physical Laboratory, it was a low-speed facility which involved the one-twentieth-scale models. Because tests showed that the models compared poorly with the actual aircraft by a factor of 20, a suggestion was made to construct a sealed airtight chamber in which air could be compressed to the same extent as the model being tested. The new tunnel, the Variable Density Tunnel was the first of its kind and has become a National Historic Landmark. (April 1, 1921)

Looking down the throat of the world's largest tunnel, 40 by 80 feet, located at Ames Aeronautical Laboratory, Moffett Field, California. The camera is stationed in the tunnel's largest section, 173 feet wide by 132 feet high. Here at top speed the air, driven by six 40-foot fans, is moving about 35 to 40 miles per hour. The rapid contraction of the throat (or nozzle) speeds up this air flow to more than 250 miles per hour in the oval test section, which is 80 feet wide and 40 feet high. The tunnel encloses 900 tons of air, 40 tons of which rush through the throat per second at maximum speed. (1947)

Guide vanes in the 19-foot Pressure Wind Tunnel at Langley Aeronautical Laboratory, National Advisory Committee for Aeronautics, form an ellipse 33 feet high and 47 feet wide. The 23 vanes force the air to turn corners smoothly as it rushes through the giant passages. If vanes were omitted, the air would pile up in dense masses along the outside curves, like water rounding a bend in a fast brook. Turbulent eddies would interfere with the wind tunnel tests, which require a steady flow of fast, smooth air. (March 15, 1950

Closed-circuit television enables aeronautical research scientists to view the ramjet, used for propelling missiles, while the wind tunnel is operating at speeds from 1500 to 2500 mph. (8.570) The tests were performed at the Lewis Flight Propulsion Laboratory, now John H. Glenn Research Center. (April 21, 1957)

The Gimbal Rig, formally known as the MASTIF of Multiple Axis Space Test Inertia Facility, was engineered to simulate the tumbling and rolling motions of a space capsule and train the Mercury astronauts to control roll, pitch and yaw by activating nitrogen jets, used as brakes and bring the vehicle back into control. This facility was built at the Lewis Research Center, now John H. Glenn Research Center at Lewis Field. (October 29, 1957)

Lockheed C-141 model in the Transonic Dynamics Tunnel (TDT). By the late 1940s, with the advent of relatively thin, flexible aircraft wings, the need was recognized for testing dynamically and elastically scaled models of aircraft. In 1954, NASA's predecessor agency, the National Advisory Committee on Aeronautics (NACA), began converting the Langley 19-foot Pressure Tunnel for dynamic testing of aircraft structures. The old circular test section was reduced to 16 x 16 feet, and slotted walls were added for transonic operation. The TDT was provided with special oscillator vanes upstream of the test section to create controlled gusty air to simulate aircraft response to gusts. A model support system was devised that freed the model to pitch and plunge as the wings started oscillating in response to the fluctuating airstream. The TDT was completed in 1959. It was the world's first aeroelastic testing tunnel. (November 16, 1962)

Alas, the names of the photographers — as is often the case with creators working on the government dollar — were not preserved. If you recognize any, get in touch and help credit them.

Meet Marty Cooper, Inventor of the Cell Phone

By:

“If you try to build a device that does all things for all people, it won’t do any of them very well.”

“Often what the world calls nonsensical, becomes practical,” Alexander Graham Bell observed in reflecting on his early work that would eventually produce the telephone. Yet how nonsensical the notion of a wireless phone must have seemed even to him at the dawn of the 20th century. But a mere seven decades later, in April of 1973, the first cellular phone made its debut. To celebrate the fortieth anniversary of the era-defining technology, filmmaker David Friedman has profiled inventor Martin “Marty” Cooper (b. 1928) in the latest installment of his wonderful series of portraits of inventors.

What’s important about any technology is that the technology is — hopefully — invisible, but at least transparent and maybe intuitive. … The purpose of technology is to make your life better. Most cell phones don’t do that very well — in fact, they force us to become engineers, to learn a bunch of new things. We shouldn’t have to do that. The ideal phone would be one where I would just talk to the phone — or maybe the phone would read my mind — and it would do things to make my life better. … If you try to build a device that does all things for all people, it won’t do any of them very well. So I think that’s where we are with cell phones today.
