Microbes | Image used for representational purpose (Photo Credits: Pixabay) Washington, February 22: As NASAs Perseverance rover touched down on Mars last week, a new study by scientists at the US space agency and German Aerospace Centre has found that some microbes on Earth could temporarily survive on the surface of the Red Planet. The researchers tested the endurance of micro-organisms to Martian conditions by launching them into the Earths stratosphere, as it closely represents key conditi...

Microorganisms are closely-connected to us, our body, our food, our environment, so it is impossible to rule them out of space travel. According to the experts, the work paves the way for understanding the threat of microbes to space missions, as well as the opportunities for resource independence from Earth. The findings have been published in Frontiers in Microbiology. “With crewed long-term missions to Mars, we need to know how human-associated microorganisms would survive on the Red Pl...

Download 10.55 MB We all know that the human microbiome, the collection of microscopic life that lives in us and on us, is intrinsically linked to our health. So how much more must microbes be important to the health of a coral reef? Nicole Webster’s made a career of studying these miniscule wonders. Guest:

 Some microbes found on Earth may temporarily survive on the surface of Mars, according to a study that could be vital for the success of future missions to the Red Planet. It comes after the Perseverance rover of the National Aeronautics and Space Administration (NASA) touched down on Mars last week. Scientists at the US space agency and German Aerospace Centre tested the endurance of microorganisms to Martian conditions by launching them into the stratosphere, the second major layer of Ear...

Date Time Stromatolites – fossils of earliest life on Earth – may owe existence to viruses As the Mars Rover sets out to look for evidence of life on another planet, scientists back on Earth suggest viruses played a key role in creating stromatolites, our planet’s earliest lifeforms.

Qin Wang et al There are microbes near the bottom of the third deepest hole in the world. The cells, recovered from rocks almost 5 kilometres below the surface in China, are the deepest so far found anywhere on land – and they may push beyond the known heat tolerances of life on Earth. A team …

Now that NASA’s Perseverance rover has landed safely on Mars, it will start taking samples and release the Ingenuity helicopter to test flying drones on other planets

Nasa rover Perseverance nears Mars Scientists hope to find signs of fossilised microbial life on the red planet 18 February 2021 - 14:34 Steve Gorman A replica of the Mars 2020 Perseverance Rover. REUTERS/JOE SKIPPER Los Angeles — The National Aeronautics and Space Administration’s (Nasa’s) Mars rover Perseverance hurtled into the final stretch of its seven-month journey from Earth en route to a nail-biting landing attempt on Thursday on an ancient, alien lake bed, ...

for a reduced atmosphere on ancient Mars The blue-toned rocks in the upper-left of the image are depleted in iron because it was removed during weathering on ancient Mars. This is geological evidence that iron was lost from the rocks in reduced conditions. Both Earth and Mars currently have oxidising atmospheres, which is why iron-rich materials in daily life develop rust (a common name for iron oxide) during the oxidation reaction of iron and oxygen. The Earth has had an oxidising a...
