NASA is at the forefront of exploring the universe, and even they can
make some mistakes that can cause disasters and destroy untouched
planets. Every space trip has to go through a comprehensive evaluation
of the plan, the structure, the possible scenarios, and the cleaning of
the spaceship to not cause any harm or colonize other planets with microorganisms from Earth, leaving behind signs that we’ve explored
other worlds, but sometimes these organisms can resist the impossible.

Former NASA mission exposed
Before launching a spacecraft, the project spends years in development
to cover every topic, scenario, and potential issue possible – but
sometimes things get out of hand. Recently, Elon Musk’s SpaceX was
testing a different number of landing profiles, but the test went awry –
the spacecraft exploded before making the last burn and splashdown in
the Gulf.

Elon Musk stated that the problem with the ship was caused by leaks that
led to a loss of pressure in the main tank in the re-entry phase. The
test flight had a secondary objective: launching a satellite for
Starlink. However, the top of the spaceship, where the satellite was
located, did not deploy. SpaceX’s spacecraft can undergo a different
type of analysis before flying since it’s not going to another planet,
but NASA’s exploration spacecraft cannot. Back in 2007, the company
failed to make the Phoenix Mars Lander 100% safe.


Scientists from the Jet Propulsion Laboratory, along with researchers
from India and Saudi Arabia, discovered 26 extremophiles –
microorganisms with strong resistance to inhospitable environments – in
the clean room used to prepare the Phoenix Mars Lander 18 years after it
was launched. The discovery indicates some of it probably went to the
Red Planet.

In order to prevent Earth’s microorganisms from going to space, NASA has
a protocol of cleaning the spacecraft in decontaminated environments
called “clean rooms,” designed specifically to prevent microbial life
from getting a ride to space.


Researchers found multiple species in a clean room
These microorganisms are very resistant and can be found in the most
extreme environments. The scientists found 53 genetic variants of 26 never-before-seen species of extremophiles. When they examined the
genomes of these newfound species, they found genes linked to DNA
repair, which means they can heal as fast as they get harmed. The lead
author of the study, Kasthuri Venkateswaran, a former scientist at NASA,
stated that these organisms have the potential to “revolutionize the
life sciences, bioengineering, and interplanetary exploration.”

The importance of decontaminating the environment
Spacecraft systems are built to work independently, without any
interference from dust, microbes, or other contaminants that might lead
a mission to fail before reaching its destination. Another motivating
factor for the meticulous analysis of the spacecraft structure before
being launch to space by NASA is that even a single Earth microbe could
cause false results in collected materials from other planets, like Mars
– if a microorganism common to our planet goes to Mars, not only it can change the results from collected data, but also leave behind traces of
life from other ecosystems.

The rovers don’t come back to Earth
Not a single rover sent to Mars has returned, but if it did, it would
need to go through a decontamination process in order not to contaminate
Earth with a microorganism unknown to humans. In 1967, during the Cold
War, the Outer Space Treaty was created in order to make space
exploration exclusive for peaceful purposes. The United States, the
United Kingdom, and the Soviet Union (now Russia) were the first
countries to sign, and two years later, NASA landed on the moon – and
they can go back before 2030, if China doesn’t get there first.
