L'India si prepara al volo umano

Il primo esperimento è riuscito, con l'obiettivo di mandare nello spazio una capsula disabitata nel 2014 ed un equipaggio umano l'anno successivo.

Space Capsule Successfully Recovered
January 22, 2007

The Space capsule Recovery Experiment (SRE-1) launched by Polar Satellite Launch Vehicle (PSLV-C7) from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota on January 10, 2007 was successfully recovered today (January 22, 2007) after being maneuvered to reenter the earth’s atmosphere and descend over Bay of Bengal about 140 km East of Sriharikota.

Since its launch, SRE-1 was going round the earth in a circular polar orbit at an altitude of 637 km. In preparation for its reentry, SRE-1 was put into an elliptical orbit with a perigee (nearest point to earth) of 485 km and an apogee (farthest point to earth) of 639 km by issuing commands from the Spacecraft Control Centre (SCC) of ISTRAC at Bangalore on January 19, 2007.

The main parachute was deployed at about 2 km altitude and finally, SRE-1 splashed down in the Bay of Bengal with a velocity of 12 m/sec (about 43 km per hour) at 09:46 am. The flotation system, which immediately got triggered, kept the capsule floating. Recovery operations were supported and carried out by the Indian Navy using ships, aircraft and helicopters.

During its stay in orbit for the last 12 days, the two experiments on board SRE-1 were successfully conducted under micro gravity conditions. One of the experiments was related to study of metal melting and crystallisation under micro gravity conditions. This experiment, jointly designed by the Indian Institute of Science, Bangalore and Vikram Sarabhai Space Centre, Thiruvananthapuram, was performed in an Isothermal Heating Furnace. The second experiment, designed by National Metallurgical Laboratory, Jamshedpur, was intended to study the synthesis of nano-crystals under micro gravity conditions. This experiment can help in designing better biomaterials having closest proximity with natural biological products. The experimental results will be analysed in due course by the principal scientific investigators of the two experiments.



The successful launch, in-orbit operation of the on board experiments and reentry and recovery of SRE-1 has demonstrated India’s capability in important technologies like aero-thermo structures, deceleration and flotation systems, navigation, guidance and control. SRE-1 is an important beginning for providing a low cost platform for micro-gravity experiments in space science and technology and return specimen from space.

ts goal would be to design, develop and launch an Indian human spacecraft, a two-seat space capsule, which would be used to send an Indian into space by 2014. The vehicle would be launched by India’s Geosynchronous Satellite Launch Vehicle, GSLV-Mk II, or GSLV-Mk III.

The project is being prepared in the form of a report for government approval and budgetary allocation in the 11th and 12th five-year plans. A manned mission into space would require about Rs. 150 billion ($3 billion) over a seven-year period.

ISRO(Indian Space Research Organisation) has maturity in many technologies required for manned space mission. However, new developments are required in life support systems, improved reliability and safety, crew escape system, etc.



Questo farebbe dell'India il quarto paese al mondo, dopo Russia, USA e Cina a raggiungere il traguardo dell'esplorazione umana dello spazio.

Cordiali Saluti

bellissima notizia, ne approfitto per chiedere: una volta realizzato il programma spaziale, quanto tempo occorrerebbe per dotarsi di icbm (o amri analoghe) insomma, quanto ci vorrebbe in termini di tempo ma anche di soldi, affinchè l'India possa dotarsi di armi in grado di colpire ogni parte del globo?

Il progetto ICBM indiano, denominato Surya è sviluppo da diversi anni e si attende per il 2008 il primo test, dovrebbe trattarsi di un missile da 5.000-8.000 Km di raggio, se vuoi ne possiamo parlare più estesamente.

Surya, il dio del sole[e non solo]: già il nome mi fa illuminare d'immenso
Surya, e Agni (il dio del fuoco[della conoscenza], e dio dei brahmana): un'ottima accoppiata
Se potessi dirmene di più te ne sarò grato, ma intanto, che significa: dovrebbe trattarsi di un missile da 5.000-8.000 Km di raggio?
