Techniques That Will Search For Life On Mars Are Tested In Australia

As it prepares for its Mars mission, NASA’s Perseverance rover underwent tests in southern Australia – especially its tools and methods that will look for evidence of microbial life forms.

“The Flinders Mountains are the perfect place to do a lot of research related to Mars because it is a dry, dusty and windy area, which is very arid and therefore a good analog for looking for life on Mars “, says astrobiologist Bonnie Teece, from the University of New South Wales in Sydney.

In an article published in the journal Astrobiology, Teece tells how he replicated the methods that the Perseverance Rover will use to select Martian rocks for analysis of biomarkers – naturally occurring molecules indicating evidence of microbial life.

In Australia, researchers searched for evidence of ancient life on Earth, analyzing different lines of evidence. “If you work with only one line of evidence, it may not be really real – it may be a contaminated artifact or it may look like life, but it is not,” says Teece. “That is why it is so important that the rover has a diverse payload of instruments that can investigate and probe sediments in different ways on Mars to look for the best candidates for life.”

The mission is scheduled to launch between July and August when Earth and Mars are in good positions with each other for the trip. Perseverance is a semiautonomist who will explore the Jezero Crater with high-tech instruments to help identify rocks on the Red Planet.

Your Mastcam-Z cameras have a state-of-the-art zoom feature that will help the mission to convert 3D images more easily. The rover is also equipped with PIXL, an instrument that uses X-rays to reveal the elemental composition of samples visible to the naked eye.

And, completing the analysis tools, is Sherloc, whose main objective is to detect organic compounds sweeping the environment using spectroscopy.

By mimicking these instruments, Teece’s team was able to identify which samples were the most degraded and which were least likely to preserve these organic products. The researchers used analogous tools to identify the rocks on the Flinders land that they later collected manually.

By simply looking at the samples, together with elementary mapping and some organic results, the team was able to gather a comprehensive description of the environments in which the fossils were. “The use of the same technology onboard Perseverance can lead to positive results in the search for signs of microbial life”, believes the astrobiologist.

NASA's Perseverance Rover is now actively looking for signs of life on Mars

After successfully landing on Mars some time ago, now NASA’s Perseverance rover is ready to look for signs of ancient microbial life on the red planet.

Previously this rover had explored a number of areas on Mars and collected rocks from the planet. But now the rover will be even more active to search for information on the planet.

Currently, the rover has 43 sample tubes which will later be filled with rock fragments and Martian dust to be sent back to Earth for further investigation. The process was carried out at four locations including Jezero.

Well, after that, Perseverance will then make a long journey to the north, an ancient river that is said to have been one of the sources of life on the planet Mars.

Scientists hope that at this location, the Perseverance rover can find minerals that can later be used to preserve fossils of ancient life after biological processes.

NASA and JPL are now also quite often providing updates regarding their rover while on Mars. Some time ago his party also uploaded a view of the surface of the planet Mars in 360-degree mode on its official YouTube account.

Scientists Say Humans Can Actually Live Longest Up To 150 Years

Scientists Say Humans Can Actually Live Longest Up To 150 Years

How long can humans actually live? Of course that is one of the interesting questions that we cannot answer for sure until now.

The reason is why don’t we research about how long humans can live like some species of turtles that can live up to 100 years or dogs that can live between 10-13 years.

For now, the oldest human in history is a woman named Jeanne Calment who has lived to 122 years and 164 days.

Quoted from Ubergizmo, recently a number of researchers named Timothy V. Pyrkov, Konstantin Avchaciov, Andrei E. Tarkhov, Leonid I. Menshikov, Andrei V. Gudkov, and Peter O have conducted a study to find out what the maximum age of humans is.

And it turns out from the study, it is stated that humans have the longest lifespan of up to 150 years. The reason is more than that, the human body will not be able to survive disease and injury at all so it is very difficult to survive.

However, to make humans able to survive up to 150 years, of course, is very difficult because now there are many factors that can ‘shorten’ human life starting from the environment, food, and others.

The researchers still believe that by doing therapy, they can extend human life or at least make the body still able to ward off disease and stay healthy for more than 150 years. What do you guys think?

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

An aviation startup is working to make hypersonic aviation a reality by allowing people to travel around the world from one place to another in just one hour.

Quoted by Bloomberg, Monday (31/05/2021), Venus Aerospace Corp. said that the spacecraft hipersoniknya will be able to carry passengers from Los Angeles to Tokyo in about an hour – low who otherwise take 11 to 13 hours.

The company is the brainchild of former Virgin Orbit LLC employee Sarah Duggleby (code-writing launch engineer) and her husband Andrew Duggleby (launch, payload and propulsion operations).

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

The idea came after the couple missed Sarah’s grandmother’s 95th birthday due to the long duration. Although we have never heard of supersonic jets – jets that travel faster than the speed of sound. Now, Venus Aerospace is developing a hypersonic jet, which is much faster than a supersonic.

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

Venus has planned a space path as fast as 9,000 miles per hour or about 14,484 kilometers per hour. This is almost 12 times faster than the speed of sound (a maximum of 1234 km/hr).

Venus currently has 15 employees and most of them are veterans of the space industry. They have received investments from venture capital firms such as Prime Movers and Draper Associates.
