Illnesses and injuries during space missions are a range of medical conditions and injuries that may occur during space flights. Some of these medical conditions occur due to the changes withstood by the human body during space flight itself , while others are injuries that could have occurred on Earth's surface.

Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F), [4] along with red skin, headache, dizziness, and confusion. [2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...

Laika was to be the "flight dog" – a sacrifice to science on a one-way mission to space. [22] Albina, who had already flown twice on a high-altitude test rocket, was to act as Laika's backup. The third dog, Mushka, was a "control dog" – she was to stay on the ground and be used to test instrumentation and life support. [9] [17]
The two dogs showed severe dehydration, weight loss, loss of muscle and coordination and took several weeks to fully recover. [ 7 ] This spaceflight of record-breaking duration was not surpassed by humans until Skylab 2 in June 1974 and still stands as the longest space flight by dogs.
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]
