Up, up and away!

This is a significant weekend for science. At 1.25am AEST Saturday, Space Shuttle Atlantis is scheduled to be launched into space for the 33rd and last time.

As I was reading up on facts for a post about the final launch of Atlantis, I found out that it is also the final launch of the NASA Space Shuttle program – making this launch the end of an era for human space travel and exploration.

Turtles Cause Airport Chaos!

There is a large population of Terrapin Turtles living in the marshes near JFK Airport, and every year they migrate to nearby sandy areas in Jamaica Bay to lay their eggs

– and there just happens to be a runway in the way.
A runway at a very, very busy airport....

Well that was really, really close!

Earlier this week, we had a close shave. An asteroid passed by the Earth at just 12,000 km. The distance between the Earth and the Moon is roughly 400,000 km. That is really, really close.

The asteroid was between 5 and 20 km in diameter and probably would have burned up and exploded upon entering the Earth’s atmosphere. But that’s not what I find most interesting about this. What is interesting is how little notice we had of its passing.

Written by Holly Kershaw on June 27th, 2011.      0 comments

Chile’s Puyehue Volcano began to erupt on June 4 of this year, and despite being 10,000 km away from the eastern states, wreaked havoc on Australian and New Zealand air travel.

How did the cloud of ash manage to travel so far?  The answer is trade winds.
