The illustration shows the advantages of launching from Kulasekarapattinam. The GSLV launch vehicle could put on orbit with an eight-degree ‘Yaw’ maneuver, whereas the launch from Sriharikota would require 14 degree Yaw maneuver. PSLV launch from Kulasekarapattinam would directly avoid Sri Lanka, whereas the same if done from Sriharikota would require a deviation to avoid Sri Lanka. — Illustration taken from report of Mahendragiri LPSC staff association. The report was sent to PMO.
Chennai: Veteran scientist and former chief general manager of the Liquid Propulsion System Ce­ntre (LPSC) in Trivan­drum N. Sivasubra­ma­nian believes that an additional 400kg equ­ip­ment could have be­en sent in the Mang­al­yaan mission but for Isro’s obsession with Sathish Dhawan Space Centre (SDSC) in Sriharikota.
The veteran scientist has revived the debate over establishing the co­untry’s third rocket launch centre at Kula­sekarapattinam, inste­ad of Sriharikota, wh­i­ch already has two launch centres. The association of staff of LPSC, Mahendragiri,  had even sent a memorandum to the Prime Minister’s Office.
Not­ably, DMK president M. Karunanidi had al­so written to the PMO seeking to establish the 3rd rocket launch centre at Kulaseka­ra­pa­ttinam, thanks to his MP daughter Kani­mozhi who personally took up the matter with PM and Congress vice president Rahul Gandhi after consulting senior scientists.
Sivasubramanian, who held the office in Mahendragiri and Va­l­l­imala among other vital Isro establishme­nts, told DC that the rocket, which put Ma­n­galyaan into orbit, co­uld have carried 1,750 kg to 1,800kg of equipment instead of 1,350 kg if it were la­un­ched from Kulase­kara­pattinam. He cit­es th­ree major reaso­ns. (i) Closeness to eq­u­ator (ii) proximity to liquid propulsion centres in Mahen­dragiri and Va­l­liamala (iii) Cond­u­ci­ve climate.
Isro top brass would have some serious answering to do, for a seven-member committee constituted last year to identify the id­eal location for the 3rd rocket launch centre, has not tabled its re­po­rt as yet.
In his Dec­em­ber 20, 2012, or­der Isro chairman K. Radha­kr­i­shnan set Fe­bruary 28, 2013, as deadline for professor K. Na­ra­yana led committee to table the report. Isro sources in the know of things revealed that the committee, had met just once since its constitution was divi­ded. While the chairman suggested some part of Krishna district, another important member wanted it in Sriharikota, sources revealed.
A PSLV rocket launched from Kulaseka­rapatti­nam could be put in orbit without a Yaw ma­neuver and even a GSLV rocket launched from there would re­quire only a 8 degree Yaw maneuver, while the same would requi­re 14 degree Yaw man­euver if launched fr­om Sriharikota, Siva­sub­ramanian reaso­ned, pointing out that instead of 300kg of ad­ditional fuel re­qui­red for the Yaw mane­uver, equipment like trans­p­onders or cameras of equal weight could be sent if launched from Kulasekarapattinam.
Lot of money could be saved in logistics by laying a dedicated rail route from Kula­sekarapattinam to LDSC in Mahen­dra­gi­ri and Vallimala from where most equipme­nt are brought for lau­nch, instead of moving it by road to Sr­i­h­a­rikota, he added.
