TheEpicSquared Posted June 4, 2017 Share Posted June 4, 2017 (edited) Thought I'd start an ISRO Discussion thread, 'cause, y'know, why not. Pretty much the same as the SpaceX/Blue Origin/ ULA threads, just for ISRO. Also, this, tomorrow. today.

Scotius Posted June 4, 2017 Share Posted June 4, 2017 This article is a bit... bombastic 6-10 tons to LEO does not place this rocket in "Heavy-weight launcher" category. Still - good going India. You deserve it after years of hard work. Quote Link to comment Share on other sites More sharing options...
Spaceception Posted June 4, 2017 Share Posted June 4, 2017 Wait, the mk3? Also, India's doing fantastic in the aerospace field, I can't wait to see what they accomplish in the future. Quote Link to comment Share on other sites More sharing options...

The "heavyweight" part is used in that article in relation to the mass of the launch vehicle on the pad, not in relation to its lift capacity to orbit.

That's only for the initial version. The semi-cryogenic core version (ULV or GSLV Mk. 3) should do 15 tons to LEO and 6 tons to GTO. Quote Link to comment Share on other sites More sharing options...

Shpaget Posted June 6, 2017 Share Posted June 6, 2017 They ignite the core booster after the launch "at exactly 114,9 seconds" 4:20 in the video. Quote Link to comment Share on other sites More sharing options...
monophonic Posted June 6, 2017 Share Posted June 6, 2017 Man that thing was fast off the pad! Like a hound! Looks like they have some growth margin for upper stages and more payload in it. Quote Link to comment Share on other sites More sharing options...

KAL 9000 Posted June 8, 2017 Share Posted June 8, 2017 How are they only getting this kind of launcher now? Didn't they send a probe to Mars? Oh, wait, they hitchhiked... Quote Link to comment Share on other sites More sharing options...
Kryten Posted June 8, 2017 Share Posted June 8, 2017 It's not actually that hard to send a small orbiter to Mars. Japan sent one up on a Mu-V, with less than 2 tons to LEO capability. Quote Link to comment Share on other sites More sharing options...

I think Mariner and some Soviet missions to Venus happened (or were at least launched) while the Gemini program was still going on, so it isn't exactly a huge technological hurdle. A number of probes have been lost even before landing, so the trip isn't exactly trivial. Quote Link to comment Share on other sites More sharing options...

Oh, wait, they hitchhiked... They didn't - Just sent one fuel-heavy probe on their light launchers ! Ends up in place weighing only half a ton. It's really impressive to see ISRO's development, particularly that they never really received help like China or some other nations. All the rockets are literally home grown !

Kryten Posted June 9, 2017 Share Posted June 9, 2017 That's not really true, there was a lot of tech transfer from france. The liquid engines on PSLV and GSLV are licence-built viking engines. Quote Link to comment Share on other sites More sharing options...

Actually, Viking Engines are derived from Vikas Engines, Vikas Engines sent Francs, for New Technological Upgrades, these Engines came to known as Vikings so Upgrded Vikas and Viking are the Same, Only a change is its Origin (Vikas) and Derived (Viking).

Kryten Posted June 11, 2017 Share Posted June 11, 2017 ISRO did have a hand in the Viking design process, but Viking is itself a modified version of the M-55 engine from the europa-3 project. M-55 was built and tested in the late 60s, years before the agreement between SEP and ISRO. Quote Link to comment Share on other sites More sharing options...
Codraroll Posted June 11, 2017 Share Posted June 11, 2017 I'm not sure if the grainy cameras are silly and outdated, or a testament to an impressive policy of making do with what you've got and not squander money upgrading things that still work perfectly. That footage from the control room looks like it was shot by cameras produced in the seventies, and they may very well roll for several more years because they still do the job they were designed to do.
