Overall efficacy won’t be clear until we get a closer look at Bennu’s makeup. “These are reasonable ideas — well thought out.”Scientists are using an asteroid named Bennu for a case study. By noting the point on the ground where the hammer hits, a measurement can be made on the image of the initial height of 2.9 hammer lengths or 113 cm.

With a planned impact speed of 22,000 miles per hour, it could impart a lot of force. Project Thor is an idea for a weapons system that launches telephone pole-sized kinetic projectiles made from tungsten from Earth's orbit to damage targets on the ground. An asteroid could fall out of the sky and knock us back into the stone age, or worse, end our brief reign on this planet. Researchers used the trajectory calculations of Each HAMMER spacecraft would weigh 8.8 tons. Sometimes they’ll include recommendations for other related newsletters or services we offer. If we don’t know about an impact years in advance, it might be impossible to alter the asteroid’s course early enough.

The "NanoTHOR" project aims to connect small satellites with upper rocket stages by using miles-long tethers, so that the rocket stages can spin the satellites around like Thor's hammer. "The professor of planetary science is leading the mission to collect rock samples from the asteroid, which he says could provide “vital data for future generations”.The Osiris-Rex probe will arrive in 2018 then spend a year surveying Bennu, which orbits the sun at 63,000mph.Scientists are hoping that information gathered on the trip will help them to work out how the asteroid’s course is affected by absorbing and radiating sunlight.NASA has also ploughed cash into a pioneering project aimed at working out how to hijack asteroids and turn them into controllable space ships.It has forked out a preliminary grant of $100,000 to a scheme designed to convert "entire asteroids into enormous autonomous mechanical spacecraft".This might sound like the half-baked plan of a super-villain, but the science behind it is dead serious.Made in Space, the firm behind the scheme, suggested commandeered asteroids could be used to save our planet from doomsday space rocks, which are commonly called Near Earth Objects (NEOs).Space disaster: Artist's impression of a 'super-impact'.

Although there’s a very small chance it could happen, a large “Smart people are taking this seriously and thinking carefully about what might be done,” MIT impact expert Richard Binzel told the website. The Hypervelocity Asteroid Mitigation Mission for Emergency Response (HAMMER) spacecraft — a collaboration between the National Nuclear Security Administration, NASA, and two Energy Department weapons labs — would either steer its 8.8-ton bulk (called an “impactor”) into a small asteroid, or carry a nuclear device to deflect a big one. What are the mysterious trails on the lunar surface near the Apollo landing sites? If it struck the Earth, it would trigger a 1.13-gigaton blast, more than 20 times larger than the biggest hydrogen bomb ever tested.
