I have noticed that we've been talking here of satellites launched by other countries... I just heard that Bangladesh is following suit and is also launching a satellite by the end of 2010. The satellite, though, will not be used for TV or cable, but for telecommunications.

Yeah that's true. And wait until you hear how much it's going to cost: $150 million to $200 million!

Cool that's great news. I was really getting tired of hearing US and European satellite launching here and there and the occasional Middle East or Russia, but alas! an Asian country tries to catch up!

That's true. Bangladesh is also trying to work with different countries in the launch. So far, it has been holding financing talks with Japan, China and the United States.

You're kinda wrong in thinking that the satellite will be used exclusively for telecommunications. Alternative uses for it will be for TV broadcastng and for the weather.

I didn't think Bangladesh would be lanching its own satellite. For one, I didn't think it would have the money for it.

Bangladesh isn't the only one that is launching a satellite. India is much closer to launching a satellite and is now working on a semi-cryogenic propulsion technology that would help the launch a six-tonne satellite. And this is not India's first satellite, mind you.

Semi-cryogenic? What is that?

Strictly speaking, cryogenics is the study of the production of very low temperatures... usually -150 celcius... that's way below the freezing point of water.

Cryogenic material may be used as fuel, specially, liquid hydrogen.

That's right. And semi-cryogenic means that it uses the same principles as cryogenics but with an important twist. India is currently trying to develop kerosene for launching its rockets.

Hmmmn... what's the point of spending so much on R&D if liquid hydrogen works?

Well, for one, aviation grade hydrogen is much cheaper. The cost savings is very substantial. If India pulls it off, they could also market the technology that makes it possible.

With all these satellites launching into space, it's a wonder why these satellites don't collide with one another!

I reckon they may use that Tom Tom Satellite Navigation :):):):)

is there really such a thing?

Uhm... I think there's an agency that takes care of satellite traffic.

Yep seen them myself in Halfords ;)

In February of 2009, two satellites collided. The irony is that it was a US satellite and a Russian Satellite that collided

That's true. Here's the link:
