Scientists create ‘concrete’ using blood, sweat, tears of astronauts for construction on Mars - ThePrint

Scientists calculated that over 500 kg of high-strength AstroCrete could be produced over the course of a two-year mission on the surface of Mars by a crew of six astronauts.

In this study, researchers found evidence of a mother spider, from what is known as the mid-Cretaceous period, exhibiting the same behaviour.

The researchers found four chunks of amber that had been extracted from a mine in Myanmar that contained entombed spiders.

The three other chunks of amber contained baby spiders and spider thread.

NASA has confirmed evidence that a region of northern Mars called Arabia Terra experienced thousands of “super eruptions” — the biggest volcanic eruptions known — over a 500-million-year period.

By studying the topography and mineral composition of a portion of the Arabia Terra region in northern Mars, scientists found evidence for thousands of such eruptions.

The researchers hope that Arabia Terra will teach scientists something new about geological processes that help shape planets and moons.

The researchers said that this would have been a slippery, sloped surface, which means that it is unlikely that people would try to cross it?

Researchers from the Copernicus Atmosphere Monitoring Service — who monitor the Ozone hole — report that it is “rather larger than usual” this year, and is currently bigger than Antarctica.

According to the agency, this year’s hole is growing quickly and is larger than 75 per cent of ozone holes at this stage in the season since 1979.

A layer of high concentration ozone exists about 15–30km above the Earth’s surface in the stratosphere.

The 2021 ozone hole ranks among the top 25 per cent of the largest ozone holes in our records since 1979, and is continuing to grow.
