Astronaut warns that this rejected NASA telescope is our best chance to avoid death by asteroids.



Former NASA ex-astronaut says that the agency that works for it is mandatory to protect civilians from the killer asteroid, but it does not meet that responsibility.

The risk of asteroid strikes seems abstract as an external scope. But the risks, while reckless, are real – and the most powerful nuclear weapons are potentially more deadly than the threat of explosion.

Death Risk From Above

In 1908, space rock is believed to be several hundred miles in diameter, which glide at Earth's atmosphere at thousands of hours, resulting in the explosion of the foreign body in the remote Tunguska region of Russia with the power of thermonuclear weapon.

The resulting blast caused trees to flatten in almost double the size of New York City.

Recently, in 2013, a massive 70-foot meteor show shot at Chelyabinsk of Russia.

The controversial fireball broke windows around Miles and sent more than 1000 people to hospitals in multiple cities, many of them with dozens of serious injuries.

We know that they are there

NASA is guarded by these types of risks – and therefore there are also legal authorities.

In 2005, the Congress created one of the agency's seven main goals to track 90 percent of 460 feet (140 meters) and larger asteroids, which could be worse than the Tunguska-level event. The time limit for legally mandatory goal is 2020.

So far, on Earth and in space, the telescope has seen less than one-third of Earth's nearest Earth objects (NEO) and NASA fails to hit its timeline almost.

Practically, this means that according to a June 2018 report published by the White House, there are a large number of thousands of neo to get out of the city.

The same report concludes that half the locations in such space will be located by 2033, with current and organizational capabilities.

We have the technology to deal with the problem

Russell "Rusty" Schwerkert, aerospace engineer retired astronaut who flies on the Apollo 9 mission, says that there is a solution to wait for this problem: NASA can launch a Nature-Earth Object Camera (NEOCAM), a small infrared observatory , In space

"It's a definitive discovery telescope to save life on Earth, and it's ready to go," Schwitch told Business Insider at The Economist Space Summit on November 1.

NOOCAM's designers have given NASA a number of missions. The mission has received several million dollars here and there to continue its development in response to the proposals, but the agency has refused to provide full funding in every instance, because it is not a purely science-targeted mission.

"Provide funds for God's sake, as a main medium program. Do not put up with science yet another competition," Schwart said. "This is a public security program."

How the NEOCAM & # 39; City Killer & # 39; Will hunt for asteroids

The telescope, which is looking at the right place at the right time, can detect the light of the spot in the black color of the space. This allows scientists to calculate the quantity, speed, orbit of the NEC and ultimately go to the Earth.

Smaller Neo, however, is not very bright. This means that a telescope should be big, look up a lot in the sky, and use the most advanced hardware to choose them. This monster takes too long to build and calibrate the telescope and budget-crushing is expensive.

For example, take the Large Synopic Survey Telescope (LSST), which is the world's best current hope for finding killer asteroids. The project was broken in 2015 and is expected to cost approximately $ 5 billion to build.

Based on its current construction schedule, by the end of 2021, it will not be fully functional, or by the middle of the 2030's, the Congress will be able to complete 90 percent of the targeted targets.

LSST, such as land based observatories, also comes with two main limitations.

First of all: "You can not see asteroids near the Sun." Mark Sykes, director of the Planetary Science Institute, and the NO OCAM team's scientist, Mark Sykes, told Business Insider that you are in the dark near the sun.

"We just have to wait until we pop up against those people."

Cycus said that the second conundrum is that ground-based telescopes mainly depend on the visible light for the discovery. "If [an asteroid] On a dark surface, it will become very difficult to see, "he said.

Because Nikoom is in place, these two problems are mentioned, where Sykes says, "You are not blind by the sky."

Telescope Advance will also use high-resolution infrared cameras. Infrared is the long wavelength of light that is invisible in our eyes, but if the source is strong – say, a roaring fire – we can heat invisible light on our skin.

Tropical asteroids will release infrared light by either the sun, the radioactive elements, or both, even if it is too small or dark to look at ground-based telescopes. Which means that the NOOCM can only detect them through their heat signatures.

This approach has already proven to work.

NASA's eight-year-old Wide-field Infrared Survey Explorer (WISE) telescope is the main example of finding an estimated 275 NEOs, in which 50 potentially dangerous asteroids or PHOs (henceforth have been named because they come to Earth on 4.6 million miles of Earth). Points in their orbit).

However, it is a less powerful telescope, it has to look at a small area, an old camera that requires cryogenic cooling which runs late (Neocam does not need it), and is not designed to detect asteroids.

The telescope, which is now called the Neois, can close operations in December 2018.

NEOCAM is the world's best immediate hope for faster search of aeroids

According to a recent study Astronomical Journal, NOOCAM or LSST alone will never receive 90% detection mood of Congress – only working together, research found that observations could achieve that goal for a decade.

But NOOCAM offers significant improvements in the situation under LSST.

In the latest pitch in NASA, the NOOCM team suggested launching in 2021 and four-year-460-foot (140 m) categories, or finding two-thirds missing items in almost a decade from the LSST schedule.

According to a report published by the National Science and Technology Council (NSTC) of the White House in December 2016, less than 70 percent of all NEO's 460 feet (140 meters) or greater size of NEO could not be found.

This is approximately 25,000 nearby asteroids and approximately 2,300 potentially dangerous.

The NTSC report suggests that circulation such as NOOCAM can help telescope asteroids in the root, which is a tunguska-type event (occurs once in approximately 100-200 years) and a Chellynsk-type event (sometimes occurring 10 years), from which Less than 1 percent.

So, if starting a more capable replacement for NEOISE is a top priority, then why did NASA not fully fund NEOCAM for the 2024 launch?

& # 39; NASA has the responsibility to do this & # 39;

In 2006, 2010 and 2015 – the team behind NOCAM has deposed NASA's mission three times – and three times NASA has provided full funding to the telescope.

Sources said that on the last few days it was refused, sources told Business Insider that the proposal did not have technical weaknesses. Instead, he was trying to jam Square Peg in the round bureaucratic hole.

The NASA Competition was a part called Discovery, the first values ​​of scientist – do not guarantee the safety of humanity – and so he has not allowed NOCM to start up to $ 450 million and develop rockets to develop its spacecraft.

NASA chose two new space missions to replace the Solar System in its place: Lucy, an investigation that will visit the ancient asteroid swarms near the guru, and the cyches, which will move all the metal parts of the dead planet.

For the part of the Shiquarket, they do not take care of the differences.

"NASA has the responsibility to do it, and it is not happening," he said. "Both NASA and Congress need to put in NASA budget."

In the bill of government funding of 2018, the Neocon got $ 35 million, but not enough to put itself on the tecospope launch pad.

"In the meantime, NEOCAM is in a zombie state and the Earth is essentially waiting in the crosshairs," said Richard Binzell, a business insider in an email addressed by an expert on the risks of asteroids in the Earth Sciences and Massachusetts Institute of Technology.

Benazir is one of the three scientists who, despite not being in the team of the project, wrote a recent OP-ad in Space News to provide full funding to the project.

Beanzl and others argue that NASA plans to increase the proposed budget of House of Representatives for new housing defense for $ 40 million (160 million USD to $ 200 million) and launch a rocket ride with a spacecraft called IAAP, to launch NO OCAM. The agency plans to launch in 2024.

Working in coordination with ground-based telescope, NEOCAM can achieve approximately 70% detection in four years, and in less than 10 years the agency's target can achieve a target of 90%.

Finding such money is not easy though. Benzyl said that the continuity of asteroid strikes makes it politically uncertain to fund another initiative after a year.

"But the consequences of being wrong are unresponsive, especially when the ability to gain the knowledge is easily understood by us," he said.

"We should only behave like responsible adults and & # 39; they should do the same. & # 39; What are we waiting for?"

Now it is on the President Trump and Congress

Schweicert acknowledged that NASA's budgeting and culture has been focusing for leading scientific research on decades, and away from this standard – rather than congressional orders – it's not easy.

"You're going upstream. You're fighting with a very strong headwind in NASA," he said, adding that funding from the science budget is very unclear to fund anybody. "But government agencies do not have the freedom to ask for an increase in their budget."

Schweizer and fellow retired astronaut Ed Lu tried a year ago to end the problem with the co-founding of the B612 Foundation, which is a dedicated nonprofit to develop Neo-Detecting capabilities.

But the group introduced its longest running (and most expensive) concept, Sentinel Space Telescope as part of reforming NEOCAM's opportunities to fund the fund. On October 29, the organization strongly supported legislation to provide full funding to its rivals.

People with Naosa also appear on the onboard, which makes an asteroid search plan like NOOCAM.

In the June poll by Pew Research, nearly two-thirds of 2,500 American adults surveyed that asteroid inspection should be a top priority for NASA. (More than just monitoring the weather changes.)

The Trump administration will decide to do with NOCAM in the next NASA budget and if the Congress authorizes the funding, then it remains to be seen.

"That's the debate in February," NASA's associate manager Stephen Jerseyzek told Business Insider at the Economist Space Summit.

"As far as the President leaves his budget to the Congress, he has all been expelled."

Circumstances of NASA's work require the discovery of dangerous asteroids and the necessary changes to work in order to take internal action.

"It is a cultural issue to some extent, where we have a pure science and pure mentality," he said.

"I think we are starting to develop a more diversified and more balanced approach between pure science and other things."

The question is whether the later Tunguska-type asteroids make changes before they come to Earth. After giving enough caution, we can throw on the rock of such a place and try to hurt people if we can not prevent the disaster or have enough time for it.
