The astronaut warns that a broken NASA telescope is our best option to avoid the asteroid


As the astronaut NASA says, the civilian agency that used to work was a duty to protect from killer asteroids, but it is not the duty to comply.

The asteroid strikes threats seem as abstract as the outer space. But the risk, while rarely happens, is real, and potentially more deadly than one of the most powerful nuclear power ever detonated.

The risk of death above

In 1908, space rock could have several hundred meters in diameter, thousands of thousands of miles per hour, the foreign body in Russia, in the Tunguska region, exploded with a thermonuclear weapon.

As a result, the trees exploded nearly twice the size of New York.

Recently, in 2013, a meteorite of 70 meters in width over Chelyabinsk (Russia).

Fireball conquered windows around miles and more than 1,000 people dispatched more hospitals than in many cities in hospitals, of which dozens of dozens of serious injuries.

We know they're there

NASA warns of these risks, and therefore they are legislators.

In 2005, the Congress made one of the seven major goals to overcome 90% of asteroids (460 meters) and higher (than the Tunguska level). The deadline for achieving this objective is 2020.

So far, Earth and space telescopes have found less than a third of the Earth's objects (NEO) and NASA will almost not exceed its deadline.

In fact, this means that thousands of thousands of people have found that a city has been eliminated enough, according to the White House published June, 2018.

According to the same report, despite the current and predicted skills, less than half of the space rock will be 2033.

We have the technology to deal with the problem

Russell "Rusty" Schweickart, a flying aerospace engineer who fled astrolabe 9 astronauts, says there is a solution to address this problem: NASA can launch Near Earth Earth Object Camera (NEOCam), a small infrared observatory in space.

"The discovery of telescope for the protection of Earth's life is critical and ready," said Schweickart Business Insider on The Economist Space Summit on November 1.

NEOCam's designers started the mission several times at NASA. It has received millions of millions of millions of dollars here and there to continue developing in response to these proposals, but the organization has repeatedly denied total funding because it is not the best science-based mission.

"From God, it has been established as a fundamental program, do not put another science challenge," said Schweickart. "This is a public security program."

How to hunt NEOCam "city killer" asteroids

Right now, the telescopes that are looking for the right spot detects the point of that light by sneaking on black space. This would allow the scientists to calculate the mass, velocity, and orbit of the NEO and the odds of reaching the Earth.

Small NEOs, however, are not too bright. This means that the telescope must be large, to see the sky and select the most advanced hardware. These monsters build a lot of time to build and calibrate these telescopes and are expensive for budget crushing.

Take the Large Synoptic Survey Telescope (LSST), for example, one of the best hopes of Earth to find the killer asteroids. The project began in 2015 and it will cost about half a million dollars.

Based on the current construction project, it will not be completed until 2021, as soon as possible, or to meet the 90 per cent target set by the Congress until the mid-2030s.

LSST, like ground-based observatories, also has two main boundaries.

First, "You can not see asteroids around the sun, you're blind in the sun," Mark Sykes, Director of Planetary Science Institute and NEOCam team scientist, told Business Insider earlier.

"Right now we have to wait until these pops come in front of us."

Sykes says the second blow is mainly grounded in light-detecting telescopes based on ground. "Yes [an asteroid] It has a dark surface, it will be difficult to see, "he said.

NEOCam deals with these two issues in space, where Sykes says "does not stick to the sky".

The telescope should also use a high resolution infrared camera. The infrared is the wavelength of the invisible light before our eyes, but if a source is sufficient, for example, as the fire is compassionate, we can see invisible light on our skin.

Asteroids, or radioactive as well as those that heat the sun, emit infrared light, although they are too small or dark to see earth-based telescopes. This means that NEOCam could only have their signature signatures.

This approach has already been proven to work.

It should be noted that the Wide-field Infrared Survey Explorer (WISE) telescope at the NASA is eight years old, of which approximately 275 NEO have been found, including 50 potentially dangerous asteroids, or PHOs. orbit in point).

However, the telescope is more powerful, it has a lower vision area, the older camera that needs cryogenic cooling (NEOCam does not need it), and it was not designed to hunt asteroids.

The telescope, now NEOWISE, can end operations in December 2018.

The fastest NEOCam Earth is the fastest discovery of asteroids

According to a recent study Astronomy Magazine, not only the NEOCam nor the LSST would achieve the "90 percent detection mandate", the investigations found only when working together, that observers have been able to achieve more than a decade.

But NEOCam offers significant upgrades to the LSST situation.

In his final NASA field, NEOCam wanted to start the group in 2021 and find two-thirds of 460-meter-wide four-item objects in four years or a decade before the LSST.

Not less than 70% of the total number of NEOs (140 meters) or more were found, according to a report published in December 2016 by the National Science and Technology Science Magazine (NSTC).

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

The NTSC report suggests that a telescope like a NEOCam will also help the asteroid that goes hand in hand with a Tunguska-type event (from 100 to 200 years) and the onslaught of a Chelyabinsk type event once every 10 years, less placed

So NEOWISE's replacement is a top priority, why is NASA not fully founded NEOCam 2024?

NASA has responsibility for & # 39;

Behind the NEOCam team, NASA performed its mission three times in 2006, 2010, and 2015; and three times, NASA has fully financed the telescope.

This last case was denied, the sources said that the proposal for Business Insider had little technical weakness. Instead, a square bureaucratic round hole should be confused.

The NASA contest, called Discovery, was first evaluated by scientists – not guaranteeing human security – so NEOCam did not give $ 450 million to develop its spacecraft and rocket.

NASA has received two new space missions to explore the Solar System: Lucy, a probe that visits the ancient asteroids, near Jupiter, and Psyche will orbit the metal orbit of the planet.

In favor of Schweickenburg, he does not make any distinction.

"NASA has a responsibility and it does not happen," he said. "The NASA budget should be put in place by both NASA and Congress."

NEOCam earned $ 35 million in the 2018 government finance bill, but it is not yet proposed to launch the telescope.

"Meanwhile, NEOCam is in a state of zombies and Earthe is inevitably waiting on the cross," said Richard Binzel, scientist and planetary scientist at the Massachusetts Institute of Technology's dangers of asteroid issues, in Business Insider email.

Binzel has a team of three scientists, recently published in Space News, to help fund the project, even if it does not have a project team.

Binzel and others say NEOCam has launched a proposed budget from NASA's $ 40 million US $ 200 Million $ 200 Million $ 200 Million $ 200 Million $ 200 Million for the NASA Planetary Defense and a spacecraft called IMAP. The Agency intends to launch in 2024.

With the ground-based telescopes, the NEOCam can achieve almost 70% detection within four years, and the agency's 90% detection has been detected in less than 10 years.

However, finding money is not easy. Binzel has said that the asteroid strikes are less politically covered, to finance other initiatives a year later.

"But the consequences of misunderstanding are negligible, especially when we understand the ability to get the necessary knowledge," he said.

"We must act solely as adults and" do it. "What are we waiting for?"

Now he is President of Trump and Congress

Schweickart acknowledged that NASA's budget and culture decades ago led to scientific exploration and diverted from that rule – whether or not Congress mandated. It's not easy.

"You're upstream. You're struggling with a powerful burial within the NASA," he said, saying that saving money from all of the science science money is not very effective at all. "But government agencies do not have the freedom to apply for a rise in their budget."

Schweickart and Ed Luduk had to face the retired astronauts a year ago to end the problem, when the B612 Foundation was created, NEO is a nonprofit dedicated to the development of detection capabilities.

However, the group presented its longest (and most expensive) initiative, the Sentinel space telescope, partly enhanced by NEOCam's opportunities. On October 29, the organization also published a strong support for parliament, fining its rival.

The public also appears together with NASA as a NEOCam for asteroid detection projects.

At the Pew Research Center in June, 2,500 adult adults accounted for almost two-thirds of the population's asteroid tracking as the main priority for NASA. (The only monitoring of climate change was greater).

The Trump Administration decides with NEOCam in the next NASA budget, and if the Congress authorizes it.

"That is a controversy in February," Stephen Jurczyk, NASA's managing partner, told Business Insider Economist Space Summit.

"This is all attached to the president until he releases his budget for the Congress."

Jurczyk acknowledged the tension between NASA's dangerous asteroids and made necessary internal changes to carry out this task.

"It is necessarily a cultural problem, where pure science and a purely mental kind of competition," he said.

"I think that pure science and other things are more balanced and balanced."

The question is whether the changes that occur prior to the next Tunguska type of asteroid reach the Earth. Once warned, we can fly this space rock and avoid any harm, or if there is no such time, people try to avoid damage.
