Russia wants to destroy Apophis before 2035

Russia’s space chief said Wednesday his agency will consider sending a spacecraft to a large asteroid to knock it off its path and prevent a possible collision with Earth.

Anatoly Perminov said the space agency will hold a meeting soon to assess a mission to Apophis, telling Golos Rossii radio that it would invite NASA, the European Space Agency, the Chinese space agency and others to join the project once it is finalized.

When the 270-meter (885-foot) asteroid was first discovered in 2004, astronomers estimated the chances of it smashing into Earth in its first flyby in 2029 were as high as 1-in-37.

Further studies ruled out the possibility of an impact in 2029, when the asteroid is expected to come no closer than 18,300 miles (29,450 kilometers) above Earth’s surface, but they indicated a small possibility of a hit on subsequent encounters.

In October, NASA lowered the odds that Apophis could hit Earth in 2036 from a 1-in-45,000 as earlier thought to a 1-in-250,000 chance after researchers recalculated the asteroid’s path. It said another close encounter in 2068 will involve a 1-in-330,000 chance of impact.

Scientists have long theorized about asteroid deflection strategies. Some have proposed sending a probe to circle around a dangerous asteroid to gradually change its trajectory. Others suggested sending a spacecraft to collide with the asteroid and alter its momentum, or using nuclear weapons to hit it.

Without mentioning NASA findings, Perminov said that he heard from a scientist that Apophis is getting closer and may hit the planet. “I don’t remember exactly, but it seems to me it could hit the Earth by 2032,” Perminov said.

He wouldn’t disclose any details of the project, saying they still need to be worked out. But he said the mission wouldn’t require any nuclear explosions.

Hollywood action films “Deep Impact” and “Armageddon,” have featured space missions scrambling to avoid catastrophic collisions. In both movies space crews use nuclear bombs in an attempt to prevent collisions.

“Calculations show that it’s possible to create a special purpose spacecraft within the time we have, which would help avoid the collision without destroying it (the asteroid) and without detonating any nuclear charges,” Perminov said. “The threat of collision can be averted.”

“People’s lives are at stake. We should pay several hundred million dollars and build a system that would allow to prevent a collision, rather than sit and wait for it to happen and kill hundreds of thousands of people,” he added.

Boris Shustov, the director of the Institute of Astronomy under the Russian Academy of Sciences, hailed Perminov’s statement as a signal that officials had come to recognize the danger posed by asteroids.

“Apophis is just a symbolic example, there are many other dangerous objects we know little about,” he said, according to RIA Novosti news agency.

“We will soon hold a closed meeting of our collegium, the science-technical council to look at what can be done” to prevent the asteroid Apophis from slamming into the planet in 2036, Anatoly Perminov told Voice of Russia radio.

“We are talking about people’s lives,” Perminov was quoted by news agencies as telling the radio station.

“Better to spend a few hundred million dollars to create a system for preventing a collision than to wait until it happens and hundreds of thousands of people are killed,” he said.

The Apophis asteroid measures approximately 350m in diameter and RIA Novosti news agency said that if it were to hit Earth when it passes nearby in 2036 it would create a new desert the size of France.

Perminov said a serious plan to prevent such a catastrophe would probably be an international project involving Russian, European, US and Chinese space experts.

Interfax quoted him as saying that one option would be to build a new “space apparatus” designed solely for the purpose of diverting Apophis from a collision course with Earth safely.

“There won’t be any nuclear explosions,” Perminov said. “Everything will be done according to the laws of physics. We will examine all of this.”

In a statement dated from October and posted on its website, the US space agency NASA said new calculations on the path of Apophis indicated “a significantly reduced likelihood of a hazardous encounter with Earth in 2036.”

“Updated computational techniques and newly available data indicate the probability of an Earth encounter on April 13, 2036, for Apophis has dropped from one-in-45,000 to about four-in-a-million,” NASA said.

RIA Novosti said the asteroid was expected to pass within 30,000 kilometres (18,600 miles) of Earth in 2029 — closer than some geo-stationary satellites — and could shift course to hit Earth seven years years after that.
