Germany to do partial gravity experiments using Zero-G airplane
In what might be the first human experiments in partial gravity, Germany has hired the Zero-G airplane for a series of flights testing how humans react in such conditions.
In the Partial G Campaign, the pilots fly three special parabolic shapes. So instead of zero-g or microgravity, one quarter, half and three quarters of Earth’s gravity will still be present. Passengers on board will therefore experience one quarter, half or three quarters of their own body weight – depending on the trajectory,” explains Stang.
The goal of these flights is to see what effect partial gravity has on human muscle control.
For humans to be able to move around and interact with their environment, they require finely tuned muscle movements, to walk around or ensure a secure footing, for instance. Under partial gravity, in particular, they must be able to effectively control their muscles via their neural pathways. If we are unable to do so, the risk of stumbling is dramatically increased. This applies to both humans on Earth and astronauts in space. However, partial gravity conditions appear to influence this neuromuscular control in challenging situations, increasing the astronaut’s risk of stumbling. Researchers at the University of Freiburg are investigating why this is so. The results are intended to reduce the risk to astronaut safety during missions to other planets, thereby resolving a fundamental safety issue in human physiological space exploration.
This is better than nothing, but it seems to me to be the least important thing to study in partial gravity. The Apollo astronauts clearly demonstrated that humans can adapt their muscle movements to partial gravity. What we must instead learn is whether partial gravity will eliminate bone loss, loss of cardio-vascular conditioning, spinal changes, balance problems, and the vision damage, all of which have been found to occur in weighlessness.
At the same time, it is probably impossible to study any of these latter issues during a short parabolic vomit comet flight. The Germans are doing what they can. Unfortunately, they might be the only ones doing anything in this area.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

In an Airbus 320, 25 seconds at a time. Difficult to even take blood pressure in that small of a period, much less get your feet under you to study balance and muscle control. However, congratulations and keep up the research!
