India rocket launches asteroid-spotting satellite

Feb 25, 2013
India's PSLV-C20 satellite launch vehicle, carrying the SARAL Indo-French satellite as one of its payloads, lifts off from the launchpad at Sriharikora on February 25, 2013, in a photo released by the Indian presidential palace. India launched a rocket Monday carrying seven satellites into orbit, including a Canadian orbiter that will scan for asteroids that could be hurtling toward Earth.

India launched a rocket Monday carrying seven satellites into orbit, including a Canadian orbiter that will scan for asteroids that could be hurtling toward Earth.

The Polar Satellite Launch Vehicle blasted off from the Sriharikota centre located on an island off the coast of the southern Indian state of Andhra Pradesh.

The launch, witnessed by Indian President President Pranab Mukherjee at the space mission control centre, "was perfect", Devi Prasad Karnik, an official of the state-run , told AFP.

The suitcase-sized Canadian satellite, which the calls a "sentinel in the sky", will circle the globe every 100 minutes, scanning space to pinpoint asteroids that may come close to Earth.

Information from the satellite could help deflect asteroids whose trajectory might threaten Earth, Canadian space officials say

Earlier this month, an asteroid whizzed safely past Earth the same day a much smaller, previously undetected meteor hit Russia, injuring nearly 1,000 people.

Near-Earth Object Space or NEOSSat "will be the only space telescope dedicated to searching for asteroids", Canadian satellite scientist Alan Hildebrand was quoted as saying by India's Hindu newspaper.

The Canadian satellite will also scan for chunks of asteroids, comets and space debris—leftovers from old space missions—that can cause collisions.

The rocket was also carrying an Indo-French satellite called "SARAL", or Satellite with ARGOS and ALTIKA—two climate monitoring tools developed for analysing ocean currents and sea surface heights by CNES.

"We will obtain crucial data for climate models and global ocean currents" from the satellite, said CNES project head Pierre Sengenes.

Learning more about is key in understanding how global warming is affecting the planet, scientists say.

The other satellites being carried into space included another one from Canada, two from Austria and one each from Denmark and Britain.

The Indian mission was the 23rd for the country's Polar Satellite Launch Vehicle or PSLV.

India, which aims to send its first manned flight into space in 2016, has emerged as a significant player in the lucrative global commercial satellite-launch market, according to space experts.

The Indian space agency has launched 35 foreign satellites since 1999 while the maximum number of satellites ever launched by the PSLV in a single mission stands at 10.
