India's SARAL-Altika satellite to study rising sea level

With ocean scientists reporting a nine mm rise in sea levels in four years, India will launch an exclusive satellite later this year to study the changes in the environment.

The SARAL-Altika satellite will complement the current observations of the sea made by current satellites like Jason-2 of the French Space Agency and NASA.

“The SARAL-Altika to be launched by this year-end will have a high-resolution altimeter in the Ka-band,” Marc Pircher, Director of the Centre National d’Etudes Spatiales (CNES), the French space agency said on the sidelines of the 97th Indian Science Congress here.

He said the satellite would be useful in studying the sea state, light rainfall climatalogy, mean sea level and coastal altimetry.

Shailesh Nayak, Secretary, Ministry of Earth Sciences, said that SARAL-Altika would help ocean scientists gather accurate data on the rise in the sea level which could threaten the low lying and coastal areas of the country.

“SARAL-Altika will have a Ka-band altimeter which will measure the rise in the sea levels accurately than the current satellites,” he said.

SARAL-Altika, an Indo-French collaboration in the environment monitoring domain, will have two independent payloads – ARGOS-3 and Altika – whose objective would be to promote the study of environment from space.

LCA's Naval version prepares to roll out

India's first indigenous Naval Light Combat Aircraft, the LCA (Navy) NP1 is scheduled to roll out from the Hindustan Aeronautics Limited (HAL) Aircraft Research and Design Centre (ARDC) design hangar on July 6.The Defence Ministry has said that the aircraft will be an important milestone for the prestigious Naval Program of Aeronautical Development Agency (ADA), Bangalore.The Chief of The Naval Staff Admiral Nirmal Verma would be the Chief Guest at the function.'Roll-Out' is a significant milestone when the aircraft is brought out of the build hangar, where the aircraft is actually assembled part by part, ready for the phase of systems integration tests leading to Ground runs, taxi trials and flight.Once the ground based tests are completed, the NP1 is expected to fly by the end of this year and the NP2 is likely to fly by the end of 2011.The aircraft, with state of the art technologies and punch, is designed to operate from the future Indigenous aircraft carriers the Navy…

Intercontinental ballistic missiles well within reach

Advanced Systems Laboratory (ASL) is the deceptively bland name that obscures from public view the Defence Research & Development  Organisation’s (DRDO’s) most glamorous laboratory. At the DRDO missile complex here in Hyderabad, ASL develops the ballistic missiles that, in the ultimate nuclear nightmare, will carry Indian nuclear weapons to targets — thousands of kilometres away. Foreign collaboration is seeping into many areas of R&D, but ASL’s technological domain — the realm of strategic ballistic missiles — is something that no country parts with, for love or for money. No foreigner would ever set foot in ASL.
But Business Standard has been allowed an exclusive visit. The erudite, soft-spoken director of ASL, Dr V G Sekharan, describes the technologies that were developed for the DRDO’s new, 5,000-kilometre range Agni-5 missile, which was tested flawlessly in April. He reveals nothing except restraint stood between India and an intercontinental ballistic missile (ICBM) that…

GSLV Mark III with crew module launched successfully

India successfully launched its biggest ever rocket on Thursday, including an unmanned capsule which could one day send astronauts into space, the latest accomplishment of its ramped-up space programme.
The rocket, designed to carry heavier communication and other satellites into higher orbit, blasted off from Sriharikota in Andhra Pradesh.
On Twitter, Prime Minister Narendra Modi hailed the test mission as "yet another triumph of (the) brilliance and hard work of our scientists."
"This was a very significant day in the history of (the) Indian space programme," Indian Space Research Organisation (ISRO) chairman KS Radhakrishnan said from mission control as fellow scientists clapped and cheered.
ISRO scientists have been riding high since an Indian spacecraft successfully reached Mars in September on a shoe-string budget, winning Asia's race to the Red Planet and sparking an outpouring of national pride.
Although India has successfully launched lighter satellit…
