Thanks to commercial spaceflights, more people are entering the cosmos than ever before.
#Nasa no gravity how to
"We haven't talked about this, because it's a professional environment," he replied to DW's question on whether astronauts exchange insights on how to handle their desires. But one topic throws even Maurer off momentarily: sex drive in space. A pendulum clock would not work in space, and there are many other mechanisms that would not work either.German astronaut Matthias Maurer breezes through interviews, rarely missing a beat when he answers journalists' questions around his upcoming six-month trip to the International Space Station (ISS). All the mechanisms based on pendulum do not work in the same way. Hanging Mass based mechanisms work in a different way. In microgravity, bones do not support the weight of anything. For example, human bodies have hard bones to let other parts of the body lean on them. Many things on Earth have internal or external structures that support everything not to let it fall. If the objetive of a research needs the fluid to remain still for a long time period under controlled temperature circumstances, a micro-g environment is perfect. This means that in such conditions fluids and gases are stiller in the presence of density and temperature differences. In microgravity there is no leaning making fluids o gases to order in such a way. On Earth, denser fluids go under lighter ones (buoyancy). Density differences do not create fluid flow.Therefore, fluids are under the effects of less forces and can be studied in different conditions. That is, liquids can be still without touching other things and without recipients pulling them up. Moreover, the ISS is always manned by operators (yes, astronauts!) who can handle the experiments.įluids do not receive reaction from the recipient it is in. The mass of the experiment equipment can be very large, only limited by the capacity of the sending procedure. In the ISS, experiments can be online for very long periods of time. These are unmanned, retrievable capsules, derived from the design of the 1960’s Soviet Vostok manned spacecraft and the Zenit military reconnaissance satellite. The European MAXUS system, for example, allows experiments which need up to 12 minutes of microgravity environments. Without reaching a stable orbit, a rocket launched vertically can achieve during certain time perfect weightlessness conditions.
European Space Agency ( ESA) owns an Airbus 300 equipped to perform such maneuvers, which give up to 25 seconds of weightlessness. The precision of this mechanism is limited, though, reducing the reaction of gravity to a hundredth. This way, the only force acting inside the airplane is the gravity (free fall). They lie in an airplane maneuvering without lift and making up for the drag of air with its engines.
#Nasa no gravity free
It is 120 metres tall and can get up to 9.3 seconds of weightlessness by means of a catapult which throws the experiment upwards, doubling the free fall longitude. The most capable in Europe is ZARM, located in Bremen. They are high towers where researchers can let their experiments fall, obtaining up to ten of seconds of weightlessness. Watts in Bristol in 1775, who first used them to build bullets. The only way to escape from the feeling of gravity is letting it make its work. It is not possible, following the physic concepts we know, to thwart the force of gravity and to reproduce the consequences of a microgravity environment without letting fall.
