Thermoacoustic combustion instabilities can be explained by distinguishing the following physical processes: the feedback between heat-release fluctuations (or flame fluctuations) with the combustor or combustion chamber acoustics; the coupling of these two processes in space-time; the strength of this coupling in comparison with acoustic losses
The survival of some microorganisms exposed to outer space has been studied using both simulated facilities and low Earth orbit exposures. Bacteria were some of the first organisms investigated, when in 1960 a Russian satellite carried Escherichia coli, Staphylococcus, and Enterobacter aerogenes into orbit. [1]
A flame trench can also be used in combination with a diverter to form a trench-deflector system. The flames from the rocket travel through openings in the launchpad onto a flame deflector situated in the flame trench, which runs underneath the launch structure and extends well beyond the launchpad itself.

It will lift off on June 25 aboard a SpaceX Falcon Heavy Rocket from NASA's Kennedy Space Center in Florida, and will provide rapid data for tracking severe storms, including destructive wildfires ...
No extraterrestrial life has ever been discovered. But if extraterrestrial life exists, it may be vulnerable to interplanetary contamination by foreign microorganisms. Some extremophiles may be able to survive space travel to another planet, and foreign life could possibly be introduced by spacecraft from Earth. If possible, some believe this ...
Space medicine is a developing medical practice that studies the health of astronauts living in outer space. The main purpose of this academic pursuit is to discover how well and for how long people can survive the extreme conditions in space, and how fast they can re-adapt to the Earth's environment after returning from space.
The explosion, which engulfed the base of the rocket in a ball of flames and heavy smoke and appeared to shake the video camera, was specific to the engine spin start test, Musk said on Tuesday.
Three of the flights had flown above the Kármán line (edge of space), and one was intended to do so. In each of these accidents, the entire crew was killed. As of December 2023, a total of 676 people have flown into space and 19 of them have died. This sets the current statistical fatality rate at 2.8 percent.
