In 1993, the U.S. Russia decided to merge their space station plans. Invite other countries to get involved in the project. The first orbiting components of the ISS were joined together in space in 1998, and the station has grown piece by piece ever since. Resident astronauts arrived in 2000. Two years later, astronauts installed Lada, the station's wall-mounted greenhouse that's used in experiments and as a source of fresh food. A second facility aboard the ISS, called the European Modular Cultivation System, is used to study plants and conduct other experiments. The astronauts run experiments on both the plants and the growth chambers, trying to learn about and improve the process of space farming. To understand the challenges of space farming, let's consider some of the elements that affect plant growth in space. Current space-farming experiments examine different aspects of farming in microgravity (a term to describe an environment with little or no gravity). These experiments could be helpful in the related case of farming on the surface of the moon or Mars, which have significantly lower levels of gravity than Earth. Acoustic levitation allows small objects, like droplets of liquid, to float. Unless you travel into the vacuum of space, sound is all around you every day. But most of the time, you probably don't think of it as a physical presence. You hear sounds; you don't touch them. The only exceptions may be loud nightclubs, cars with window-rattling speakers and ultrasound machines that pulverize kidney stones. But even then, you most likely don't think of what you feel as sound itself, but as the vibrations that sound creates in other objects. The idea that something so intangible can lift objects can seem unbelievable, but it's a real phenomenon. Acoustic levitation takes advantage of the properties of sound to cause solids, liquids and heavy gases to float. The process can take place in normal or reduced gravity. In other words, sound can levitate objects on Earth or in gas-filled enclosures in space. coronavirus stimulus package
