India is established as a Major Space Power



The Indian Space Research Organisation (ISRO) has created history by launching 104 satellites in one go from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, on Wednesday, February 15 morning. The Polar Satellite Launch Vehicle (PSLV) of the ISRO first launched the 714 kg Cartosat-2 Series satellite of India, for earth observation, followed by the INS-1A and INS-1B, after it reached the polar Sun Synchronous Orbit. It then went on to inject 103 co-passenger satellites, together weighing about 664 kg, in pairs. In this historic launch, the ISRO scientists have used the XL Variant – the most powerful rocket – earlier used in the ambitious Chandrayaan and during the Mars Orbiter Mission (MOM). This flight of C-37 of PSLV was a largely commercial flight as all but three passenger satellites, small nanosats, belonged to six other countries. The 29-minute launch went off precisely as planned; it took just 11 minutes from the release of the primary Cartosat-2 series spacecraft to the last launch of a client satellite, ISRO said after the mega-payload launch.
The PSLV, in the category of launch vehicles that can lift relatively light loads to space, now marks 38 successful missions in a row out of a total of 39 flights. It deserves all the praise this time, it took to space a total of 1,378 kg, of which the main satellite was 714 kg. This latest Cartosat launched on February 15 is the fifth in the series of six Cartosat-2 spacecraft, starting from Cartosat 2 in 2007 and followed by what were earlier marked A, B, C, D and E. The last one is due to be launched. This feat of India has overhauled Russia’s record of 37 launches created in 2014.
This is perhaps the most widely acclaimed world record of Bharat in the field of space technology. The country has reason to be proud for this global achievement. ISRO can take pride in its frugal innovation which is most cost-effective demonstration of Bharat, when it is emerging as a serious player in a crowded satellite launch market. However, foe higher Payload of 2 tonne and above, we have to employ the Geosynchronous Space Launch Vehicle (GSLV). Still, it is a hard-won achievement for India to have achieved after a long history to reach current space technology level with a relatively very small investment.  India has launched a lunar probe in 2008 and ranked first among Asian countries by having an unmanned rocket orbit Mars in 2013, at a unbelievably petty cost of Rs. 450 crores. India would spend merely a little over $1 billion a year on its space programme compared with US’ budget of about $19.3 billion for 2017. China had spent $6.1 billion in 2013. But our achievements are no. mean, in comparison to the other 5 space-powers.
One of the main beneficiaries of the Indian space agency’s launch of a record 104 satellites with a single rocket was a US firm that operates the largest privately owned constellation of Earth-imaging satellites. With such a meager budget, Bharat has proven its proficiency in the kind of rocket that launched a record number of satellites at one go on Wednesday, now the country has to focus more upon future growth of the indigenous Geosynchronous Satellite Launch Vehicle (GSLV) programme that needs more perfection. Through the Polar Satellite Launch Vehicle (PSLV), which was used on February 15 to deliver 104 satellites into Earth’s orbit and which has been the most reliable work horse of Indian space programme, notching up about 40 successful launches since 1994. But, to carry communication satellites weighing above 2,000kg into space, we would need Geo Synchronous Satellite Launching Vehicle (GSLV). To compete with countries such as France or China for the $300 billion global space industry too India needs to further improve upon its GSLV programme, as the country has and also forces it to hire foreign space firms to launch its own heavy satellites.
Now, the country’s GSLV programme too has to be activated and be made reliable and vibrant, equally after having successfully launched twice a home-built cryogenic engine, after successfully overcoming more than a decade of setbacks. The GSLV behaving as the ‘naughty boy’ of ISRO also needs to be worked upon now. It is in offing and our scientist would achieve it soon.  The first time we launched a GSLV was in January 2014, and this launch of the GSLV-D5 has put ISRO on the map of a select club of nations that can launch heavy satellites. The agency again successfully launched a GSLV-Mk II rocket in September 2016. Country’s aim should now be to become proficient in GSLV launches capable to carry payload category of 4500-5000 kg, The big fortunes of space business lies into that.Bottom of Form
So Indian space scientists, are now rightly working upon developing the GSLV-Mk III launch vehicle which is expected to deliver payload weighing 4500 to 5000kg. Since the Russian and French rockets can carry four times more payload and into higher orbits. So, India must also set an ambitious target for it. Now when we are already on the way ahead in targeting GSLV Mk II and then Mk III and a series of launch activities have already been planned to ensure that. ISRO’s has a very long term ambitious plan to undertake more than 50 missions and deploy 500 satellite communications transponders by 2019. Bharat is poised to emerge as the most cost effective player in space launch market of $ 300 b. So we would be a space super power to be reckoned with. India is almost prepared to come with its own mini space shuttle. Trail of the same on a pilot basis has already been conducted in May, 2016. Country is also planning for Mangalyan 2 in March, 2018.
