Scientists have designed a nuclear weapon-wielding spacecraft powerful enough to deflect a 1600-ft asteroid currently circling the sun.

Set for multiple close encounters with Earth over the next hundred years, there is a  chance - however vanishingly small - that the asteroid Bennu could one day collide with our planet.

But don’t worry—NASA has a plan to save us all. And it involves nukes.

Very small risk of collision

NASA lists 78 dates on which Bennu has a tiny chance of colliding with Earth. Taken together, they give an impact risk of one in 2700—small, but not impossible.

Asteroid impacts can be devastating. Some 66 million years ago, the impact of a 9-mile asteroid is widely believed to have wiped out most of Earth’s dinosaurs. In 2013, a 65-ft asteroid entered the skies above Russia, exploding over Chelyabinsk Oblast. The blast caused extensive damage and injured nearly 1,500 people.

Scientists from NASA, the National Nuclear Security Administration and two Energy Department weapons labs have designed a spacecraft to deflect an asteroid. Their research was published recently in the journal Acta Astronautica.

Nuclear explosion or colliding spacecraft?

Called the Hypervelocity Asteroid Mitigation Mission for Emergency Response, or HAMMER, the "impactor" spacecraft would be deployed to deflect a small asteroid with its own bulk. In certain cases, however, it would set off a nuclear weapon.

“If the asteroid is small enough, and we detect it early enough, we can do it with the impactor,” physicist and study co-author David Dearborn of the Lawrence Livermore National Laboratory told BuzzFeed News. “The impactor is not as flexible as the nuclear option when we really want to change the speed of the body in a hurry.”

NASA wants to change the way we think about the habitable zone

  NASA wants to change the way we think about the habitable zone Earth is just one of many possible models for sustaining life.That's Dr. Cynthia Phillips, a planetary geologist at NASA's Jet Propulsion Laboratory. She's currently working on a mission to study Europa, one of Jupiter's icy moons with a subsurface ocean. Jupiter -- and, by association, Europa -- is well outside of the "habitable zone," the gauge astronomers have used for years to determine whether a planet can sustain liquid water, a major precursor for life. But in Phillips' view, being outside of this zone doesn't automatically mean the moon or planet is devoid of life.

In an ideal situation, lots of these spacecraft would fly into the path of the asteroid. As it would plow through them it would be pummeled by 22,000mph collisions. These collisions would hopefully slow down the asteroid enough to divert its trajectory.

“You have to be careful not to slow it down just enough to go from hitting the [side] of the Earth to hitting its center,” Dearborn said.

The growing field of planetary protection

Unfortunately for us vulnerable earthlings, HAMMER is a plan which may never be built. The proposal is one of a growing number of potential planetary protection efforts developed following a 2010 National Research Council report that called for the development of NEO hazard mitigation plans.

Researchers modelled their work on Bennu because the asteroid is the best-studied near Earth object. It zipped past Earth in 1999 and again in 2005, but it won’t have another close encounter until 2054, NASA predicts. In September 2135 it may come as close as one-third the distance to the moon.

“Smart people are taking this seriously and thinking carefully about what might be done,” MIT impact expert Richard Binzel, who was not involved in the study, told BuzzFeed News. “These are reasonable ideas—well thought out.”

“Hopefully we won't need an asteroid deflection plan,” he added. “But until we search, we don't know.”

NASA wants your help checking its satellites — so send in your cloud pics .
NASA is asking all cloud gazers to snap photos of the sky and share them with the space agency via an app. The instruments are part of a project called Clouds and the Earth’s Radiant Energy System (CERES), which aims to better understand what roles clouds play in global climate change, among other things. Clouds, however, are sometimes hard to identify from up high. For example, thin, wispy cirrus clouds, the most common type of high cloud, are difficult to spot against a background of snow, according to NASA. That’s why satellite observations need to be compared with observations from the ground. Hence, the cloud observation challenge.
