Trump's waist closed to the destruction of the world!

On Thursday, the House of Representatives' Space, Science and Technology Committee met with scientists to discuss a relatively exciting issue. What can NASA do if we identify a dangerous asteroid in the way of dealing with Earth? Given all the recent conflicts about the asteroid of YR3, which was closely approaching our planet's collision, this is important before scientists corrected and identified it safely.
Most of Thursday's talks on the NASA's Near Earth (Neo) mapping mission (NEO) were to greatly improve the capabilities of dangerous asteroid detection capabilities in general. However, there have been many efforts to address the main issue: the Trump administration has recently announced that it plans to reduce NASA's main budget for the next fiscal year by 5 %. However, the proposed decrease in the budget of the agency's scientific programs, which includes planetary defense activities, is even deeper and equal to 2 %. This will be a decline in the NASA's biggest decline in American history.

"If this plan is approved by the Trump administration, NASA will put NASA on the path of insignificance," said Valerie Foushee (Democrat of North Carolina). This plan threatens our economic and national security, entrusts the US leadership and atmosphere to our enemies, and endangers our competitiveness and position on the world stage. This is a strategic position that I simply can't accept.

What is the mapping of objects close to the ground?

NASA says the mapping mission near Earth will be carried out by a space telescope that will find asteroids that can be threatened to the Earth. This is NASA's next major step in promoting the country's planetary defense, which was specifically proposed to the public in the year with the Dart mission.

Dart, which stands for Double Asteroid Redirection Test, sent a spacecraft to deal with an asteroid called Dimorphohos that rotated around a larger asteroid called DIDYMOS. It is clear that neither of these two asteroids threatened the Earth, and that was just a mission to prove the concept. The goal was to see if you can see the Demorfus route around us with a collision. If so, it shows that one day a spacecraft can be sent to a truly threatening asteroid to divert it from the possible way to the Earth. Dart worked well.

The mapping mission of objects close to Earth is a preventive measure of planetary defense. It will be a mission that identifies the asteroid that we might want to beat a dart spacecraft.

"We do not know any great heavenly crime that has a significant risk to deal with land in the next five years," said Nicola Fox, Nicola Fox, director of the NASA scientific mission.

He added: "This mission improves NASA's ability to discover and then improve the size and orbit of asteroids to understand the danger they really create for us." Finding these potentially dangerous asteroids is still the top priority of the NASA Planetary Defense Program.

One of the most promising aspects of this mission is that it can identify objects close to Earth through infrared. Infrared wavelengths are not visible to the human eye and most human technologies. They are usually regarded as thermal signs. For example, firefighters can use infrared wavelengths to understand the distribution of fire in a burning building.

This diagnosis strategy works better than traditional methods that are usually based on the reflection of sunlight from an asteroid. In fact, the problem of relying on sunlight to hunt dangerous asteroids by explosion of Cheliabinsk asteroids over Russia in the year, which damaged many buildings and injured more than five people.

Brian Babin, who is currently serving as chairman of the House of Representatives' Space, Science and Technology Committee, said during a hearing, the explosion released about 5kg of TNT, more than 5 times the Hiroshima bomb, which broke the windows, and thousands of dollars. Since the asteroid was approaching the sun, it was not detectable by ground telescopes and was not tracked.

Although the mission of exploring objects close to Earth would still not be able to identify the possibly dangerous asteroid that comes directly from the sun, it allows to see asteroids close to Earth near our star.

"This helps us find the objects, including the dark part of the asteroid population, which we think is about 5 % or more of their population," said Amy Mainzer, the main researcher and professor at the University of California, Los Angeles. It also helps us in the measurements.

"We are tracking the circuits of all 6,000 asteroids near the current known, including more than two and a half thousand potentially dangerous cases, each of which will be devastating," said Matthew Payne, director of the small planet's center.

Fox says the mission of exploring objects near the ground should be ready to launch by year 3, but this is assumed to receive the funding it needs.

White House budget documents for Year 2 show that proposed reductions could lead to the closure of NASA's Gaddard Space Center in Maryland. The outlook for the closure of such a key agency's key research center concerns scientists, and this was raised during the meeting.

Fox was asked what would happen if the NASA's Ames Research Center in Silicon Valley, which plays a vital role in planetary defense, would happen.

Fox explained: If this center is no longer able to evaluate, what we will lose is in fact the ability to provide initial expert advice to the Federal Emergency Management Agency.

Payne said that the center of small planets has not been affected by the proposed reduction at the moment; Mainzer said he is not sure how these reductions could affect the excavation of asteroids near Earth. He also emphasized how expensive the training of scientists like himself to lead such an important mission can be.

Repeating this uncertainty, Fox said: "We are waiting for the President's full budget to see the priorities in a way that may be supported or not supported."

Zoe Lofgren (Democratic-California), a representative of Zoe Lofgren, said during the meeting: "It is clear that a planet defense uses many of our federal agencies." Now, whether the federal agency continues to work and whether its expertise continues. He added that other Trump orders, such as the widespread expulsion of employees and deferred resignation programs, cause brains to escape.

For example, recent executive orders have led to the rapid expulsion of more than 5 employees of the National Oceanic and Atmospheric Administration (NOAA) that monitor natural disasters such as storms and predict daily climatic patterns. The deferred resignation program is a kind of indirect way to expel employees, and if they voluntarily leaving, they will be offered salaries for up to a specific month.

The representative of George Whitesides (Democratic California), who previously worked in NASA on the leadership, said during the meeting: "A very logical question is whether NASA should actually monitor and defend more money due to the catastrophic risk for our country and civilization?" As several members have mentioned earlier, our leadership, like many areas of space and land sciences, is now at risk due to the proposed declines of NASA budget and other scientific agencies.

"We are talking about effects that can destroy the whole area, destroy a country, or destroy the planet," Payne said. And you know, this is what we can do about. In fact, it is a natural disaster that if we do our research, 5 % can be prevented.

Exactly how our planetary defense strategies can be affected depends on the details of Trump's budget that has not yet been released. If the White House really reduces the budget of these efforts, NASA may need to rely on global partners to track asteroids close to Earth.

"If we can't all unite about a big crime that comes to our planet, then what do we want to unite?"
