A Homeland Defense for Planet Earth

http://www.space.com/images/h_impactor_02.jpg

Earth is on a "hit list" with hazardous asteroids and comets being nature's own terrorism from the sky. More than 100,000 dangerous near-Earth objects exist - known in sky watching circles as NEOs.

More than 100,000 dangerous near-Earth objects...
Nature's way of telling us that money spent on the space program is in our best interest.

Noah's Ark, revisited -- if you're into that sort of thing.

Since the Chinese are going to put their very own space station up there by 2015, may be they will watch for us and watch us too...I will not be surprised if they copy the space station of 2001: Space Odyssey with gravity and all....

You are not serious are you?

About time too, we cant keep on depending on the US to explore our solar system. The Russians and the European space agencys are just crap.

Russia is getting into a space programme with Australia. We'll be launching from Christmas Island.

Ok, so now we are back to 3...

More Asteroids in Main Belt, New Infrared Survey Says

A systematic survey of the asteroid belt done in infrared wavelengths indicates that there could be two or three times more large asteroids, those more than 1 kilometer (0.6 miles) in diameter, than had been thought

Deadly Impacts Come in Twos
05 April 2002: Scientist argue over whether and how often impacts by comets and asteroids have caused mass extinctions. Evidence is clear for the extinctions, in the form of fossils. Impact evidence is harder to find. A new study suggests that multiple impacts may have sometimes caused the demise of species in the past. Michael Lucas, a geology student at Florida Gulf Coast University, cites one example of a 73-million-year-old double impact structure referred to as Kara and Ust-Kara in Russia. “Approximately ten percent of the impact structures on Earth are doublets or twin structures, suggesting a nearly simultaneous impact of binary asteroids or fragmented comets,” he said at a regional meeting of the Geological Society of America yesterday. In recent years, several asteroids have been found to have satellite companions.

Big ass Husband and Wife rocks...trying to commit suicide....:D or may be it is a binary life system such that when they are combined they spread life on different planets...Universe works mysterious ways....

If the rest of the space agencies are 'just crap' why are we relying
on Canadian robot arms, Italian cargo containers, and Russian taxi,
escape, and supply vehicles?

Just curious. :rolleyes:

Economic necessity. Bartering again wins out over actual transfers of hard cash. ;)

None of them can afford the cash Rent.

I recall seeing an interview on TV with a USA astronaut just after the first docking of a USA shuttle with Mir space station. They had used a Russian adapter ring for the docking. The astronaut said it was about the best space mechanical tech he'd ever seen, far better than NASA's gear. Also note than Russia has had functioning recycling gear in space for 15 or 20 years, and the USA is only now catching up.

Suggest you take a look at what ESA, European Space
Agency, has on the boards:

<a href =http://www.spacedaily.com/news/rlv-02g.html ><font color =red> The Jules Verne </font></a>

An automated delivery/space tug that will provide for six
month turn-arounds rather than the present three month
ones and could possibly be used as a temporary refuge.

Needless to say, Soyuz will still by required since the NASA
has given up on a return vehicle (AKA lifeboat).

Take care :eek:

PS Please excuse the dumb comment: " ... the station loses some
200 metres (650 feet) in altitude each day because of the Earth's
gravitational pull." rather than 'because of atmospheric drag'. ;)

Russia is getting into a space programme with Australia. We'll be launching from Christmas Island. Really?
I didn't know that
why arn't they using womara?

I will be suprised if we will see any extraterrestrial, orbital structures with artificial gravity any time in the near future until we learn much more about how to manipulate gravity. The sheer cost of building a station and the nessasary attactments for gravity generation are prohibitive.

Not if all the trillion dollar countries pitch in....and assemble the parts in China...

Woomera is still used for tests and such, but it is at a lower climb than Christmas Island. Christmas Island is much nearer the equator. It's cheaper to get things into orbit, particularly high orbit, from nearer the equator.

never thought of that (but then i don't know much about space rocketry)

Thanks for pointing it out
