Moonwalking Practice 1963-1968

Wondering if it is possible to experience outer space life  here on Earth? Via Interweb3000, a photo series cataloging training for NASA astronauts in the mid-1960s:

I’ve browsed back a bit in the NASA photo archives and put together a couple of photos that have emerged of the 1960s as part of the Apollo program in the Lunar Landing Research Facility. The photographs show, as were then tested with very simple methods, the effects of weightlessness on the human body in a moon walk – of course, could also be filming the big moon landing conspiracy.

Earth (Usually) Has Two Moons

Two MoonsSo reports MIT's Technology Review:
Back in 2006, the Catalina Sky Survey in Arizona noticed that a mysterious body had begun orbiting the Earth. This object had a spectrum that was remarkably similar to the titanium white paint used on Saturn V rocket stages and, indeed, a number of rocket stages are known to orbit the Sun close to Earth. But this was not an object of ours. Instead, 2006 RH120, as it became known, turned out to be a tiny asteroid just a few metres across--a natural satellite like the Moon. It was captured by Earth's gravity in September 2006 and orbited us until June 2007 when it wandered off into the Solar System in search of a more interesting neighbour. 2006 RH120 was the first reliably documented example of a temporary moon ...

Planet Earth Has A Stalker

Earth StalkerMichael Reilly reports in the New Scientist:

An asteroid 300 metres in diameter is stalking the Earth. Hiding in the pre-dawn twilight, it has marched in lockstep with our planet for years, all but invisible to our telescopes.

The rock is Earth’s first confirmed Trojan, which can orbit the sun in either of two gravitational wells along the same orbital path as our planet. From the sun’s point of view, these wells lie 60 degrees ahead of and behind the Earth, at Lagrange points where gravitational forces between the sun and the Earth balance out.

Trojans are common — Jupiter alone boasts about 5000, and Neptune and Mars each have their own smaller collections. But finding Earth’s has proven difficult, because the Lagrange points lie towards the sun in the sky. Astronomers must look for the objects just before the sun rises or after it sets, and until now the glare of this sunlight has obscured the feeble light reflected from any rocks that might be hiding there.

NASA: There Is A Space-Time Vortex Around Earth

Doctor Who VortexAh, now we know why the Doctor visits our planet so often. Via NASA’s website:

Einstein was right again. There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein’s theory of gravity.

Researchers confirmed these points at a press conference today at NASA headquarters where they announced the long-awaited results of Gravity Probe B (GP-B).

“The space-time around Earth appears to be distorted just as general relativity predicts,” says Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission.

“This is an epic result,” adds Clifford Will of Washington University in St. Louis. An expert in Einstein’s theories, Will chairs an independent panel of the National Research Council set up by NASA in 1998 to monitor and review the results of Gravity Probe B. “One day,” he predicts, “this will be written up in textbooks as one of the classic experiments in the history of physics.”

Time and space, according to Einstein’s theories of relativity, are woven together, forming a four-dimensional fabric called “space-time.” The mass of Earth dimples this fabric, much like a heavy person sitting in the middle of a trampoline.

How to Fall 35,000 Feet — And Survive

Parachute On FireDan Koeppel writes in Popular Mechanics:

You’re six miles up, alone and falling without a parachute. Though the odds are long, a small number of people have found themselves in similar situations — and lived to tell the tale.

6:59:00 AM, 35,000 Feet: You have a late night and an early flight. Not long after takeoff, you drift to sleep. Suddenly, you’re wide awake. There’s cold air rushing everywhere, and sound. Intense, horrible sound. Where am I?, you think. Where’s the plane?

You’re 6 miles up. You’re alone. You’re falling.

Things are bad. But now’s the time to focus on the good news. (Yes, it goes beyond surviving the destruction of your aircraft.) Although gravity is against you, another force is working in your favor: time. Believe it or not, you’re better off up here than if you’d slipped from the balcony of your high-rise hotel room after one too many drinks last night.
