Chandrayaan-1 Enters Deep Space

 Chandrayaan-1 Enters Deep Space  

Chandrayaan-1 spacecraft has entered deep space after crossing the 150,000 km (one and a half lakh km) distance mark from the Earth.  This happened after the successful completion of the spacecrafts third orbit raising manoeuvre today (October 26, 2008) morning.

During this manoeuvre which was initiated at 07:08 IST, the spacecrafts 440 Newton liquid engine was fired for about nine and a half minutes. With this, Chandrayaan-1 entered a much higher elliptical orbit around the Earth. The apogee (farthest point to Earth) of this orbit lies at 164,600 km while the perigee (nearest point to Earth) is at 348 km. In this orbit, Chandrayaan-1 takes about 73 hours to go round the Earth once.

The antennas of the Indian Deep Space Network at Byalalu are playing a crucial role in tracking and communicating with Chandrayaan-1 spacecraft in such a high orbit..The spacecraft performance is normal. More orbit raising manoeuvres are planned in the coming few days to take Chandrayaan-1 towards the Moon.

CARTOSAT-2A and IMS-1 Cameras Switched on

The Polar Satellite Launch Vehicle (PSLV-C9) launched India’s Remote Sensing satellites CARTOSAT-2A and Indian Mini Satellite-1 (IMS-1) along with eight nanosatellites successfully on April 28, 2008 from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The telemetry data received indicates that all the subsystems of both the satellites are functioning satisfactorily and the health of the satellites is normal.

On April 29, 2008, the Multispectral camera onboard IMS-1 was switched on and high quality imagery covering Allahabad to Rameswaram was obtained. Today (April 30, 2008), the Hyper Spectral Imaging (HySI) camera onboard IMS-1 and panchromatic (PAN) camera onboard CARTOSAT-2A were switched on. Imagery from HySI camera covered Uttarakhand to Karnataka passing through Delhi and Bhopal. PAN camera covered strips of land from Saharanpur to Nuh (South of Delhi) and Sangli to Goa Coast. Data was received at National Remote Sensing Agency (NRSA), Shadnagar, Hyderabad. Quality of the imagery received is excellent.

Launch of PSLV-C9 is a significant milestone for the country, as it has again proved the reliability and versatility of PSLV and its ability to put satellites in different types of orbits, thus proving its commercial potential as well. This provides an excellent opportunity to undertake commercial launches of different class of satellites as stand-alone launches or as shared launches with our own satellites.

Indian Company fabricates Special Satellite Hardware for ISRO

A private Indian company M/s Avasarala Group, Bangalore, has successfully fabricated Heat Pipes for use in ISRO satellites. The first batch of heat pipeswere delivered by Shri A Mangapathi Rao, Chairman of the Avasarala Group of Companies to Dr P S Goel, Director, ISRO Satellite Centre at a simple functionon December 30, 2002.

The technical and financial assistance for producing these sophisticated heat pipes was provided by ISRO, as part of its initiative to encourage and develop vendors for production and testing of space hardware for ISRO's use. The Axially Grooved Aluminium Ammonia Heat Pipes are used in satellites to quickly transport heat from one zone of the satellite to another.

Thus they help in equalizing the temperature on all zones of the satellite equipment panels inspite of the heat generated by some of the instruments on the equipment bay. Specifically, these heat pipes are used in high power communication satellites for controlling the temperature of transponders and the related electronic systems.

BEL Hands Over Satellite Hardware to ISRO

In a brief function held this afternoon (October 30, 2002) at Antariksh Bhavan, Bangalore, the Headquarters of ISRO, Dr V K Koshy, Chairman and Managing Director, Bharat Electronics (BE) formally handed over the Invar Filters to Dr K Kasturirangan, Chairman, ISRO. These Invar filters, which are very sophisticated and precision components, are to be used in the communication transponders of INSAT-3E and future spacecraft. The Invar Filters are the first batch of space-qualified components produced by BE under a contract with ISRO's Space Applications Centre, Ahmedabad, signed in March 2000.

BE is also producing C-band and Ku-band receivers for ISRO's communication satellites, which involve the use of microwave integrated circuits and are to be assembled under clean environment. ISRO has transferred the technology for the Invar Filters and Receivers to BE besides training BE personnel in their production. ISRO has funded BE for setting up specific facilities required for producing space hardware in addition to allowing it to make use of ISRO's sophisticated facilities like the Electronic Beam Welding. Besides satellite components, BE has also received orders from ISRO for the supply of ground terminal equipment like Mobile Satellite Services reporting terminals and L-band Demodulators.

It is expected that BE will supply space hardware worth about Rs 200 Crore in the next five years.

Since its inception, ISRO has been striving to involve the Indian industries in its space programme. With the substantial increase in the scope of the space programme, both in terms of number of launch vehicles and satellites being developed and launched by ISRO, the efforts to involve industry is receiving further fillip. The ISRO efforts are now aimed at making the industries graduate from supplying parts and components to supplying major systems required by ISRO's satellites and launch vehicles. Delivery of the Invar Filters by BE today is the result of one such effort.
