Gravity Tractor Will Save The Earth From Asteroids



Vidi stellam de caelo cecidisse in terram, et data est illi clavis putei abyssi. (Revelation 9:2)

The Telegraph reports British space scientists have designed a new special spacecraft - a gravity tractor.

The gravity tractor can save the Earth from a catastrophic asteroid collision.

The 10 ton gravity tractor would be deployed to intercept an asteroid en route to the Earth.

The gravity tractor has the ability to fly 160 ft alongside an asteroid.

From this position, the 10 ton craft is able to exert a small gravitational force on the rock, pulling the asteroid towards it.

By gradually modifying its course - over several years - the gravity tractor is able to slowly shift the asteroid's trajectory enough to ensure it misses the Earth.

Scientists believe it is only a matter of time before an asteroid comes close enough to the Earth to be a threat.

There are more than 100.000 asteroids orbiting near the Earth that are large enough to destroy a city.

So far NASA has only been able to identify and track 6.363 of them.

Dr Ralph Cordey, science and exploration business development manager at Astrium, said: "Anything bigger than 30m (32 yards) across is a real threat to the Earth".

In 2004 an asteroid known as Apophis caused concern after it was calculated to pass alarmingly close to the Earth.

Projections of its path around the sun predicted it had a one in 37 chance of hitting the planet in 2029 - the highest threat in recorded history.

The threat of a 2029 collision was later ruled out.

But the asteroid could still pass through a key point in space known as a "keyhole".

That would put the asteroid on course to collide with the Earth in 2036.

Let us hope gravity tractors will find life threatening asteroids with 15 - 20 years to spare.

Jesus Christ is Lord God throughout all ages, and the world is without end, compare with Ephesians 3:21.

"Wherefore comfort one another with these words", see 1 Thessalonians 4:18.
