I do agree with you. But there are other ways to do the same. Instead of going through the whole process to build up such a heavy center and maintaining it, which is even more tough case then building one, IMO ISRO should look for future collaboration.dont worry ISRO will not get disracted.ISRO was made for doing science and research to extend our capabilites for the betterment and upliftment of society..
Right now ,ISRO is becoming sort of Commerical space industry good but we need to focus on science..as far as launching satellites ,payload is concerned ISRO is planning to erect few Private players in India like spaceX..
so that they get freed from this repititive job of launching satellite,which will give more time to ISRO to allocate its fund in exploring space and new related tech.
like you i use to think Space station is bull and why should we copy others.. but in fact if you are planning to push human exploration in space .Space stations are must in order to study human physciology,vrious physcial phenomena etc in micro /zero gravity.effect of radiation, plant growth, fluid flow , how fire spread ,,from little to big things all works different in zero gravity..
MANY RESEARCH DONE IN SPACE HAVE BEEN FOUND FRUITFUL ON EARTH
understanding of such things will enable any space organisation to plan their missions in deep space - like mars,moon,asteroids etc in a better way with minimal failures.. No other sapce prg will share you their experiments , so you have to develop your own station
DEVELOPING space station is a long curve . it will not happen overnight or in 2 years. it takes time ,so you plan early and plan well.
space sattion in future will not be just restricted to Reasearch but will also serve as spacecraft assembly Yard, resting station for deep space missions.may serve as a Railway Junction to moon ,mars..
Look at NASA, why they are talking about decommissioning ISS and not giving any clear view of any further venture in this field. The only factor which seems plausible right now is funds in maintaining it. Look at other partnering countries like JAPAN, EU and CANADA's role in ISS. Do you think they are playing any less role then US or Russia? CANADA had gifted one of the most important part to NASA, the CANADA ARM.
So instead of moving towards one full fledged Space Station, we could simply collaborate with other space agencies for using one right now. Through this way we could be in a win win situation instead of taking a much longer and expensive Space Station buildup. Its just like sending Rakesh Sharma up in Soyuz as of now instead of talking about undertaking Mission Colombia.:biggrin2:
