It's Asteroid Day and we still can not see scary issues – Quartz


The United Nations wants you to be aware of asteroids. I want to be aware of you: Humans-humans-they do not know where all the horrific asteroids are.

June 30 is the day for this activity because on this day in 1908, an asteroid explosion occurred in a Tirstuska, Russia, which destroyed thousands of acres of forest. More recent examples: Last December, a large asteroid collapsed on Bearing C, which was 10 times more powerful than the Hiroshima nuclear bomb. It was not tracked in advance, but NASA's satellite imagined fireball accidentally from space:

Naturally, astronomers have decided to find asteroids that can intersect with the Earth. They have discovered more than 8,000 so far, but researchers believe that there is a third of asteroids near our planet. Thankfully, bigger asteroids have been found to be larger than one after the dinosaurs' extinction. But if the astronomers are right, the solar system is still more than thousand that can destroy the cities or the entire region to affect the Earth.

US Congress also involved politicians after passing the law in 2005. The law requires that NASA finds 90% of the Earth's nearest objects (it's a word of art here), which is larger than 140 meters in diameter by 2020. It has been known for a few years now that NASA will not determine the time limit. There are no resources yet to find all these asteroids.

One option would be the Large Synergistic Survey Telescope or LSST built around a tennis court-shaped mirror on the Chilean mountain. In 2023, the telescope will start 10-year surveys that researchers expect that near as many as 75% of the nearest objects of the Earth will be the largest.

According to a new report from the National Academy of Sciences, there will be plenty to find and it will require a space telescope. It has come to the conclusion that infrared sensor in space allows the asteroids to pass closely. The infrared sensor is also unique to understand the size of asteroids more quickly: In the spectrum of visible light, astronomers are hard to distinguish between large, dark objects and small, bright ones, but thermal data is collected on infrared wavelengths. It can be used to solve the problem.

The obvious choice here is AOOCM, which Dr. A space telescope proposed by a team of scientists led by Amy Myniorer, who is studying asteroids and designing sensors for approximately 15 years. She told me in April, "You have to go out and look with the right tools so that they can be seen closely before they are found on earth." "The question is, when will the next time scale on human time and on the geological time scale?"

In a March hearing, NASA's administrator Jim Bridestine suggested that the recently launched TESS telescope can help fulfill the order, but it has been said that it will be done after the introduction of the NOOCM mission. "Senators said," Evidence is clear – there is no space program in dinosaurs. "" We will. So we need to be ready to do what we need to keep our planet safe. "

NASA's planet defense officer Lindley Johnson said that a one-day reminder will be issued to prepare a mission to stop deadly asteroids. In April, he said that the Space Agency is waiting to complete NAS studies, which is in full-momentous mission as a green-lighting NOCM. After completing the report now, the manager says that his team still has to move forward to advance to the next stage of the development of Space Agency.

However, there is public choice. A survey of May 2019 by the Associated Press and the National Opinion Research Council found that 68% of American adults supported programs to track asteroids, making it the top priority for NASA activities, especially compared to human missions on the Moon or Mars.
