PSLV Successfully Launches India’s Multi Wavelength Space Observatory ASTROSAT
PSLV-C30 is carrying Astrosat, along with six other co-passengers, one satellite each from Indonesia and Canada, and four nanosatellites from the US. With the successful launch of Astrosat, India gained an entry into the select club of nations having its own space observatory after the US, Japan, Russia and Europe. In its thirty first flight (PSLV-C30) conducted September 28, 2015, India’s Polar Satellite Launch Vehicle successfully launched ASTROSAT, the country’s Multi Wavelength Space Observatory along with six foreign customer satellites into a 644.6 X 651.5 km orbit inclined at an angle of 6 deg to the equator. The achieved orbit is very close to the intended one. This was the thirtieth consecutive success for PSLV.
PSLV was launched PSLV Successfully Launches India’s Multi Wavelength Space Observatory ASTROSATits heaviest ‘XL’ version with six strap-on motors of the first stage. The launch took place from the First Launch Pad at the Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota, the spaceport of India.The 320 tonne, 45 m tall PSLV-C30 carrying seven satellites including the 1513 kg ASTROSAT
Through 30 successful flights during 1994-2015 period, PSLV has launched a total of 84 satellites. The vehicle has repeatedly proved its reliability and versatility by successfully launching satellites into a variety of orbits including polar Sun Synchronous, Geosynchronous Transfer and Low Earth orbits of small inclination thereby emerging as the workhorse launch vehicle of India.
So far, 51 satellites have been launched by PSLV for customers from abroad. Today’s launch of six co-passenger satellites by PSLV-C30 was facilitated by Antrix Corporation Limited, the commercial arm of the Indian Space Research Organisation (ISRO), a government of India Company under the Department of Space (DOS).
ASTROSAT is India’s first dedicated multi wavelength space observatory. This scientific satellite mission endeavours for a more detailed understanding of our universe. ASTROSAT is designed to observe the universe in the Visible, Ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum simultaneously with the help of its five payloads.
ASTROSAT was realised by ISRO with the participation of all major astronomy institutions including Inter University Centre for Astronomy and Astrophysics (IUCAA) of Pune, Tata Institute of Fundamental Research (TIFR) at Mumbai, Indian Institute of Astrophysics (IIAP) and Raman Research Institute (RRI) of Bangalore as well as some of the Universities in India and two institutions from Canada and the UK.
International customer satellites of PSLV-C30
LAPAN-A2 is a Microsatellite from National Institute of Aeronautics and Space-LAPAN, Indonesia. LAPAN-A2 is meant for providing maritime surveillance using Automatic Identification System (AIS), supporting Indonesian radio amateur communities for disaster mitigation and carrying out Earth surveillance using video and digital camera.
NLS-14 (Ev9), a Nanosatellite from Space Flight Laboratory, University of Toronto Institute for Advanced Studies (SFL, UTIAS), Canada. It is a maritime monitoring Nanosatellite using the next generation Automatic Identification System (AIS).
Four LEMUR nano satellites from Spire Global, Inc. (San Francisco, CA), USA, are non-visual remote sensing satellites, focusing primarily on global maritime intelligence through vessel tracking via the Automatic Identification System (AIS), and high fidelity weather forecasting using GPS Radio Occultation technology.
