Life from Earth could live on Mars, according to scientific findings that could have a major effect on future space missions.
Microbes, such as fungi and bacteria, can survive in conditions similar to those found on the Martian surface, said Nasa and German Aerospace Centre researchers.
They sent micro-organisms by balloon into the Earth’s stratosphere, which comes close to replicating conditions on the Red Planet. When the balloon returned, the scientists discovered that some of the microbes had survived the trip.
The findings, published in Frontiers in Microbiology, mean scientists now better understand the threat of microbes to future space missions.
“We successfully tested a new way of exposing bacteria and fungi to Mars-like conditions by using a scientific balloon to fly our experimental equipment up to Earth’s stratosphere,” said Marta Filipa Cortesao, an author of the study based at the German Aerospace Centre in Cologne.
“Some microbes, in particular spores from the black mould fungus, were able to survive the trip, even when exposed to very high UV radiation.”
Nasa's Perseverance space probe landed on Mars on Friday in a quest to determine whether life existed on the planet billions of years ago.
Over several years, Perseverance will attempt to collect 30 rock and soil samples in sealed tubes to send back to Earth for analysis in the 2030s.
Scientists searching for extraterrestrial life must ensure that anything discovered has not merely travelled there from Earth.
“With crewed long-term missions to Mars, we need to know how human-associated micro-organisms would survive on the Red Planet, as some may pose a health risk to astronauts,” said joint author Katharina Siems, who is also based at the German Aerospace Centre.
Martian conditions are not easily replicated on the surface of our planet, but the area above the ozone layer in Earth’s middle stratosphere is remarkably similar.
“We launched the microbes into the stratosphere inside the Marsbox payload, which was kept at Martian pressure and filled with artificial Martian atmosphere throughout the mission,” Ms Cortesao said, referring to the Microbes in Atmosphere for Radiation, Survival and Biological Outcomes experiment.
“The top-layer samples were exposed to more than 1,000 times more UV radiation than levels that can cause sunburn on our skin.”
"While not all the microbes survived the trip, one previously detected on the International Space Station, the black mould Aspergillus niger could be revived after it returned home," Ms Siems said.
This month, the UAE released a close-up image of Mars captured by the Hope probe as it aims to uncover more secrets about the Red Planet.
The picture was posted on Twitter by Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai.

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.

Top investing tips for UAE residents in 2021
Build an emergency fund: Make sure you have enough cash to cover six months of expenses as a buffer against unexpected problems before you begin investing, advises Steve Cronin, the founder of DeadSimpleSaving.com.
Think long-term: When you invest, you need to have a long-term mindset, so don’t worry about momentary ups and downs in the stock market.
Invest worldwide: Diversify your investments globally, ideally by way of a global stock index fund.
Is your money tied up: Avoid anything where you cannot get your money back in full within a month at any time without any penalty.
Skip past the promises: “If an investment product is offering more than 10 per cent return per year, it is either extremely risky or a scam,” Mr Cronin says.
Choose plans with low fees: Make sure that any funds you buy do not charge more than 1 per cent in fees, Mr Cronin says. “If you invest by yourself, you can easily stay below this figure.” Managed funds and commissionable investments often come with higher fees.
Be sceptical about recommendations: If someone suggests an investment to you, ask if they stand to gain, advises Mr Cronin. “If they are receiving commission, they are unlikely to recommend an investment that’s best for you.”
Get financially independent: Mr Cronin advises UAE residents to pursue financial independence. Start with a Google search and improve your knowledge via expat investing websites or Facebook groups such as SimplyFI.
