The Russian module of the International Space Station (ISS) has an air leak that has NASA concerned.
On 2 January 2004, a minor air leak was detected on board the ISS. [2] At one point, five pounds of air per day were leaking into space and the internal pressure of the ISS dropped from nominal 14.7 psi down to 14.0 psi, although this did not pose an immediate threat to Michael Foale and Aleksandr Kaleri, the two astronauts on board.
One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.

The SBIRS satellites are a replacement for the Defense Support Program early warning system. They are intended to detect ballistic missile launches, as well as various other events in the infrared spectrum, including nuclear explosions, aircraft flights, space object entries and reentries, wildfires and spacecraft launches.
