New NASA images of the Sahara Desert reveal the scale of the sand and dust cover

2020-06-30

According to foreign media reports.According to NASA disclosures, on June 23 and 24, local time, a dust plume covered Mexico's Yucatan Peninsula and was moving into southern Texas at the same time.By June 24, the thickest part of the dust column had expanded from the 1,500 miles covered on June 18 to 5,000 miles. While propagated dust particles like this one could potentially have a negative impact on human breathing, this event wasn't entirely bad.

NASA notes that particles spread from the dust storm could also help establish beaches and fertile land. In addition, the widespread effects of Saharan dust storms may also eventually help reduce or even suppress the intensity of tropical cyclones.

Colin Seftor, an atmospheric scientist at NASA's Goddard Space Flight Center, was the one who produced this latest image. He explained: "While it is not uncommon for Saharan dust to travel across the oceans to the Americas, the scale and intensity of this particular event was quite unusual. In addition, if you look out from the coast of Africa, you can see another huge cloud drifting in from the continent and then towards the Trans The Atlantic's long chains of dust transport energy."


Getting to Mars is the biggest dream, the Mars program is becoming clearer, and the lunar space station is critical

The closest distance between Earth and Mars is also 54.6 million kilometers, which does sound a lot farther away, but we need to be aware that Earth and There is also the Moon between Mars and Mars, so scientists plan to use the Moon as a "springboard" to get to Mars. This "springboard" is in fact a series of lunar programs, in which the realization of the lunar surface base, lunar orbiting space station is the lunar program of the Focus.

An ancient civilization, more exaggerated than the pyramids, had a super black technology that cut stone with precision.

For example, the three largest pyramids, led by the Pyramid of Huf, were built in 15,000 B.C. in exact correspondence with the "three stars of Orion's belt", and the size of the pyramids also reflects the different luminosities of the three stars.
