Later, 600 thousand years, NASA Martian rock returns to his home planet

On the eve of the start of the mission, “NASA Perseverance 2020”, scheduled on 30 July, NASA announced an unusual cargo that will travel to Mars onboard the new Rover. This is the subject, which once belonged to the red planet – a fragment of Martian meteorite Sayḩ al Uhaymir 008 (SaU 008). People decided to return to his home in pursuit of two goals: the practical and the symbolic.

With symbolism, everything is simple – it is a bright infopovod, which has lately become a space projects of the Americans (for example, launch into space and the Tesla Roadster – no good, but mediapovod excellent). Stone SaU 008 was formed 450 million years ago, he was resting peacefully in the soil of Mars, while 600-700 thousand years ago, a big asteroid strike or comet knocked him into space. There he wandered, until about 1000 years ago, landed in Oman. Scientists have studied it thoroughly and now ready to return to Mars precious gift which has enriched our science.

From a practical point of view, more complex and interesting. First, SaU 008 – one of the most durable of the Martian meteorites at the disposal of earthlings, other samples send in this way is risky. Second, in SaU 008 preserved gas bubbles, identical to the composition of the ancient Martian atmosphere. The mineral composition of the meteorite and other parameters became the basis for the calibration of the latest and most important detector Perseverance SHERLOC. He will be using laser to study the composition of Martian rocks with unprecedented precision.

It is the accuracy and sensitivity of the instrument and became a decisive argument. Scientists know exactly what to expect from the well-studied SaU 008, therefore, the analysis of Martian soil SHERLOC will use the meteorite as a reference, a starting point in search of new specimens. The instrument will calibrate on the go, will be more noise immune and efficient in operation.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
