Design of an XCOR Lynx spacecraft (XCOR Aerospace)

On The Hunt For High-Altitude Microorganisms

Article Updated: 26 Apr , 2016



The United States Rocket Academy has announced an open call for entries in its High Altitude Astrobiology Challenge, a citizen science project that will attempt to collect samples of microbes that may be lurking in Earth’s atmosphere at the edge of space.

Earth’s biosphere has been discovered to extend much higher than once thought — up to 100,000 feet (30,480 meters) above the planet’s surface. Any microorganisms present at these high altitudes could be subject to the mutating effects of increased radiation and transported around the globe in a sort of pathogenic jet-stream.

What sort of microbes may exist at the upper reaches of the atmosphere?

Citizens in Space, a project run by the U.S. Rocket Academy, is offering a $10,000 prize for the development of an open-source and replicable  collection device that could successfully retrieve samples of high-altitude microorganisms, and could fly as a payload aboard an XCOR Lynx spacecraft.

XCOR Aerospace is a private California-based company that has developed the Lynx, a reusable launch vehicle that has suborbital flight capabilities. Low-speed test flights are expected to commence later this year, with incremental testing to take place over the following months.

Any proposed microbe collection devices would have to fit within the parameters of the Lynx’s 2kg Aft Cowling Port payload capabilities — preferably a 10 x 10 x 20 cm CubeSat volume — and provide solutions for either its retraction (in the case of extended components) or retrieval (in the case of ejected hardware.)

The contest is open to any US resident or non-government team or organization, and submissions are due by February 13, 2013. The chosen design will fly on 10 contracted Lynx flights in late 2013 or early 2014, and possibly even future missions.

Ah yes, that is an interesting subject. For some astrobiology background, Marlow is the go to guy. He notes that this is as of yet a hypothesis: “Indeed, thousands of microbial species have been found in the upper atmosphere, traveling up to thousands of kilometers. The best-studied “atmospheric bridge” is between North Africa and the Caribbean. Each year, up to one billion tons of dust are swept up by Sahara winds, and with a million bacteria per gram of sand, enormous quantities of biomass come along for the ride. The upper atmosphere is not a particularly hospitable environment, and researchers have traditionally assumed that the dry, UV-zapped, nutrient-poor environment would kill off any stowaways. And although the jury… Read more »

Not too surprising to see some of the crank science promoted by Wickramasinghe mentioned here. Some of his other recent pro-panspermia “research” includes:

-his finding that the Red Rains of Kerala are likely living “cells” deposited by a comet:

-SARS is extraterrestrial in nature:

I do agree that further (legitimate) research of high altitude biota is sorely needed. Maybe Citizens in Space can lead the way.

I want one of those!
