What is Space Blanket?

Thermal insulation is based on the use of substances with very low thermal conductivity. But sometimes the most effective way to protect persons or devices from leakage or gain of heat is to use a thermal radiation insulator.

Thermal radiation does not require any medium for energy transfer. Moreover, energy transfer by radiation is fastest (at the speed of light) and it suffers no attenuation in a vacuum.

In contrast to heat transfer by conduction or convection, which take place in the direction of decreasing temperature, thermal radiation heat transfer can occur between two bodies separated by a medium colder than both bodies.

For example, solar radiation reaches the surface of the earth after passing through cold layers of atmosphere at high altitudes.

In order to insulate thermal radiation, space blankets (depending on the function, also known as a Mylar blanket, emergency thermal blanket or safety blanket) can be used. Space blankets were first developed by NASA in 1964.

The highly reflective insulators are often included in emergency kits (therefore emergency thermal blankets) and are also used by long-distance runners after finishing a race to avoid a large swing in body temperature. Space blankets are designed to reflect heat back to body or deflect heat when used as a shelter from the sun, they can be used to insulate everything from the Mars rovers to marathon runners, from satellites to sun shields, and from rockets to residences.

It is one of the simplest, yet most versatile spinoffs to come out of the Agency. Highly reflective foils in radiant barriers and reflective insulation systems reflect radiant heat away from persons and living spaces, making them particularly useful in very cold climates.

What is The International Space Station?

The International Space Station is a large spacecraft. It orbits around Earth. It is a home where astronauts live. The space station is also a science lab. Many countries worked together to build it. They also work together to use it. The space station is made of many pieces. The pieces were put together in space by astronauts. The ISS consists of pressurized modules, external trusses, solar arrays and other components. ISS components have been launched by Russian Proton and Soyuzrockets as well as American Space Shuttles. The space station's orbit is about 220 miles above Earth. NASA and other space agencies uses the station to learn about living and working in space. The first piece of the International Space Station was launched in 1998. A Russian rocket launched that piece. After that, more pieces were added. Two years later, the station was ready for people. The first crew arrived in October 2000. People have lived on the space station ever since. Over time more pieces...

What is Cloud Seeding?

Clouds are made up of tiny water droplets called cloud droplets. Groups of cloud droplets form water vapour (gas) or ice crystals. Water vapour isn’t dense enough to fall to the ground as precipitation. Instead, it rises into the sky and becomes supercooled. Eventually, it condenses (turns to a liquid) around tiny particles of dust in the sky. These tiny particles are called condensation nuclei. It takes billions of these condensed water droplets to form a visible cloud. When the water molecules are spread out, they aren’t dense enough to feel Earth’s gravity. When the molecules huddle together, they form larger, heavier droplets. Eventually, they become heavy enough to fall to the ground as precipitation. Cloud seeding involves modifying a cloud’s structure to increase the chance of precipitation. Cloud seeding adds small, ice-like particles to clouds. Usually, silver iodide particles are used. These particles act as additional condensation nuclei. Unatta...
