The website discusses the presence of microbes in Earth's stratosphere, their similarity to common microbes on Earth, and their potential for global movement. It also covers historical high-altitude experiments by the U.S. and Soviet scientists.
The claims regarding microbial life in the stratosphere and their global movement are well-supported by multiple sources, confirming their presence and ability to survive extreme conditions. The similarity of these microbes to common Earth microbes is also corroborated by evidence. Historical claims about Soviet experiments with microbe collectors in the mesosphere are supported by historical records. Overall, the evidence strongly supports the factual nature of these claims.

Mostly True
Science
Earth's stratosphere contains tiny single-celled microbes that can survive extreme conditions.
The evidence supports the claim that Earth's stratosphere contains microbes capable of surviving extreme conditions. Multiple sources, including Caister Academic Press and Nautilus, confirm the presence of microbes like Bacillus subtilis in the stratosphere, which can endure harsh environments similar to those on Mars.
