Live:Sixth Cartosat-2 satellite launch(Along with 30 nano)

[B@tt!eDoom]

What>?

Sorry.I mistyped & wasn't aware about actual numbers..15 different countries Now happy?

Cartosat has military applications.

Cartosat has military applications.

It has 0.6meters resolution

Can anyone please tell, how much money we make from these launches? Thanks in advance.

This one would be around 15 mil USD in pure profit for the foreign ones launched I would estimate.

Very reliable vehicle. We don't need to post every launch here anymore b/c we know it's going to function perfectly!

I think the payload was kept low intentionally (or in effect PSLV-XL chosen instead of lighter configurations) to have the extra buffer needed for the 4th stage re-ignition tests (55 second mark):

Given if needed, 1.7 tons can be lifted to SSO by PSLV-XL.

@dreamer4eva divide my earlier estimate by about 2 -3 times, I assumed the foreign satellites were much higher total mass.

PSLV is no longer a thriller.
Congratulations!

This is wrong:

Nanosatellite classification is applied to any satellite below 10 Kg.

At 15 Kg, its no nano or pico.

How come no pak or chinese member congrats us after this success ?
Are relations on this site strained ?

Oh my, welcome my dear to have a pleasant stay!

The low payload is a surprise as they used the XL configuration.
Most of the satellite weight for gslv gto launch is the fuel required to reach geo from gto.
But for pslv why they cant increase satellite life by increasing fuel load of satellite is surprising.
The deorbit trials is a reason but isro should now optimize the lives of their satellites by using most of the launch vehicle capacity.

Well they could have gone for PSLV-CA, but thats cutting it close with the buffer for the 4th stage tests...probably have none left over:

I honestly have little idea as regarding the price sensitivity analysis regarding the boosters (XL or G config)/total rocket....I would imagine not a huge deal (its HTPB essentially)...so ISRO probably figured it was worth it for the orbiting re-ignition tests (to better target more market spectrum for exotic nano sat orbits etc in same mission).

As for increasing satellite life, it really depends. Sometimes the most critical (life determining) factor is not the orbit stationing fuel onboard but simply the electronics life, panel life, component life etc etc (Esp nano and micro sats where there is almost no shielding and a minimal thermal budget etc most of the time).. after all its SSO not LEO (where orbit stationing fuel is going to more of an issue a lot of the time).

Ahhh, we were wondering why there were no Pakistanis in this thread.

Good observation.
Although media reports can be excused to carry typographical errors.
In any case, the payloads are successfully placed in orbit and that is enough reason to rejoice.
