What is GSLV
I just read the news that India tested GSLV for 16 minutes. What does it
do, how far does it take us into the space? |

This should help: http://www.isro.org/gslvd1/gslvd1.htm The rocket is designed to put satellites into geosynchronous orbit- this is an orbit so high that the satellite circles the Earth only once every day, and therefore seems to stand still in the sky, allowing it to be used for telecommunications by a receiver or transmitter antennae that doesn't need to be moved to follow it across the sky. (The lower the orbit is, the faster the satellite moves across the sky- in very low orbits a satellite can go around the Earth 16 times a day.) GSLV is an interesting design in that it's main stage is solid fueled, with four liquid fueled boosters attached to it... in most cases the main stage is liquid fueled, and the attached boosters are solid fueled.

Pat Flannery GSLV is also interesting for its use of Viking engines (of Ariane 1-4 fame) in the strap-on boosters and second stage, and for its cryogenic (LH2/LOX) third stage. The LH2 upper stage, India's first, vaults that nation into the space launch big leagues by giving GLSV a Delta II/Soyuz/Fregat-class GTO capability. The initial GSLV upper stage was powered by a Russian engine - an engine developed for a never-flown Russian upper stage. Now India is developing its own LH2 engine to replace the Russian engine. The test described above was a long-duration test of that new engine. - Ed Kyle |

What ever happened to all the MTCR thrashing that was going on about that engine a few years ago? That's why India is developing its own. The US jumped up and down about MTCR and scuttled the original deal which had the Indians buying the engine technology from the Russians, a peculiar business since LH2 engines are not terribly useful for missiles. The replacement deal has them buying a few engines, but no technology lessons or manufacturing rights. They're doing their own as a long-term solution. sarcasm Hooray for MTCR. /sarcasm -- MOST launched 30 June; science observations running | Henry Spencer since Oct; first surprises seen; papers pending. | |
