In a First India to Have Its Own Telescope in Space

By PTI Published: 27th September 2015

NEW DELHI: If all goes well, India will be the first country in the developing world to have its very own telescope in space.

India's very own turbo-charged 'mini Hubble Telescope' is ready for lift off. If successful, the Indian space agency will join a very select club, since only the USA, European Union and Japan have similar capabilities. China lacks a space observatory.

India's first space observatory is ready and will be launched into space on the morning of September 28. This satellite is really akin to the mythical 'third eye of Lord Shiva' as it can view the Cosmos in ways the human eye is not capable of observing.

It will be used to study black holes and analyse how stars and galaxies are actually born and how they ultimately die....

Astrosat, India's first dedicated space observatory launched successfully
http://www.firstpost.com/india/astr...-at-10-am-today-2446968.html?utm_source=fp_hp

Bengaluru:
Astrosat, India's first dedicated space observatory, was launched on Monday at 10 AM from the spaceport of Sriharikota in Andhra Pradesh. It is aimed at studying celestial objects.

PSLV-C30 carrying Astrosat along with six other co-passengers, one satellite each from Indonesia and Canada, and four nanosatellites from the US.

Mission Readiness Review (MRR) committee and Launch Authorisation Board (LAB) that met on September 25 had cleared the launch of PSLV-C30.

Commenting on the launch, Indian Space Research Organisation Chairman AS Kiran Kumar had recently said, "What it means for India is this: it is one of the first scientific missions which will be available to the Indian researcher community as an observation opportunity. This is a starting point for such things."

Astrosat is India's first dedicated multi-wavelength space observatory. This scientific satellite mission endeavours for a more detailed understanding of our universe.

One of the unique features of Astrosat mission is that it enables the simultaneous multi-wavelength observations of various astronomical objects with a single satellite, ISRO said.

Astrosat will observe the universe in optical, ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum, whereas most other scientific satellites are capable of observing a narrow range of wavelength band.

Astrosat with a lift-off mass of about 1513 kg will be launched into a 650 km orbit inclined at an angle of 6 deg to the equator by PSLV-C30.

According to ISRO, after injection into Orbit, the two solar panels of ASTROSAT will automatically deployed in quick succession. The spacecraft control centre at Mission Operations Complex (MOX) of ISRO Telemetry, Tracking and Command Network (ISTRAC) at Bengaluru will manage the satellite during its mission life.

ISRO said the scientific objectives of Astrosat mission are to understand high energy processes in binary star systems containing neutron stars and black holes, to estimate magnetic fields of neutron stars and to study star birth regions and high energy processes in star systems lying beyond our galaxy.

The mission is also to detect new briefly bright X-ray sources in the sky and to perform a limited deep field survey of the universe in the ultraviolet region.

Astrosat scheduled for five years of flight carries four X-ray payloads, one UV telescope and a charge particle monitor.

Apart from ISRO, four other Indian institutions - Tata Institute of Fundamental Research, Indian Institute of Astrophysics, Inter-University Centre for Astronomy and Astrophysics and Raman Research Institute-are involved in payload development.

Two of the payloads are in collaboration with Canadian Space Agency and University of Leiscester, UK, ISRO said.

What is the orbital velocity with which Astrosat was placed? When I looked at the launch video it showed close to 7km/s when the 4th stage got separated. It is suppose to be 7.5km/s for an orbit of 650km. If not 7.5km/s wont it fall down earlier than its expected life term?

ASTROSAT, India's Own Space Observatory: 10 Things To Know


Sriharikota: ASTROSAT, India's first space research observatory, was successfully launched into orbit by the Polar Satellite Launch Vehicle today. With this, India has joined a select club of nations having such capability.
Here are the top 10 things to know about the launch:
  1. The Polar Satellite Launch Vehicle (PSLV) C-30 carrying ASTROSAT and six other satellites lifted off from Sriharikota in Andhra Pradesh at 10 am today. It successfully placed them into orbit 25 minutes later.
  2. ASTROSAT was placed almost 650 kilometres above the surface of the Earth. It is expected to have a mission life of five years.
  3. It is India's first dedicated multi-wavelength space observatory and will help scientists intensify space exploration efforts by studying distant celestial objects and conduct deeper analyses of star systems.
  4. The satellite weighs over 1500 kgs and has been assembled at the Indian Space Research Organisation or ISRO's Satellite Centre in Bengaluru. It took the agency Rs. 178 crore and 10 years to make it. The idea was conceived more than 20 years ago. The six other satellites (four from the US and one each from Indonesia and Canada) together weighed 118 kg.
  5. According to ISRO, ASTROSAT will observe the universe in optical, ultraviolet low and high energy X-ray regions of the electromagnetic spectrum, while most other satellites are capable of observing a narrow range of wavelength band.
  6. The scientific objectives of ASTROSAT mission are to understand high energy processes in binary star systems containing neutron stars and black holes, to estimate magnetic fields of neutron stars and to study star birth regions and high energy processes in star systems lying beyond our galaxy. The mission is also aimed at detecting new briefly bright X-ray sources in the sky and performing a limited deep field survey of the universe in the ultraviolet region.
  7. So far, only US, Japan, Russia and Europe have own observatories in space.
  8. This is the first time that an Indian rocket launched satellites from the US. The launch came hours before a scheduled meeting between Prime Minister Narendra Modi and US President Barack Obama in New York.
  9. ASTROSAT is seen as a smaller version of NASA's Hubble Space Telescope that was launched in 1990. It will be able to detect objects in multiple wavelengths such as X-rays, but with far lower precision than Hubble, scientists have said.
  10. The launch was witnessed by Union Minister of State for Science and Technology Y S Choudhry, who later congratulated ISRO scientists and said the space programme was "exactly going as per our Prime Minister's vision and plan." "Relationships our country is now harnessing and nourishing is the reason ISRO was able to launch American satellites from here" he said.
