 Preparations are on for the lift-off of the Polar Satellite Launch Vehicle (PSLV-C18) from the spaceport at Sriharikota at 11 a.m. on October 12.
Global tropical weather

The rocket will put four satellites in the orbit: Megha-Tropiques, built by India and France to understand global tropical weather and climate; SRM Sat, built by the students of SRM University, near Chennai; Jugnu, a satellite integrated by students of the Indian Institute of Technology (IIT), Kanpur; and VesselSat from Luxembourg.

The information sent by the instruments on board the Megha-Tropiques will help understand the behaviour of Indian monsoons and occurrence of cyclones, floods and droughts.
Heat shield

 The PSLV has been fully integrated, said K. Radhakrishnan, Chairman, Indian Space Research Organisation (ISRO), on Tuesday from Bangalore. "The Megha-Tropiques and the three co-passenger satellites have been fully integrated with the vehicle. The heat-shield was closed last morning." The heat-shield around the satellites protects them from the intense heat during the launch and the vehicle's ascent into the atmosphere. After the rocket reaches a certain altitude, the heat-shield falls off.

 Dr. Radhakrishnan said the final checks were under way. "On October 8, we will have a launch rehearsal. The vehicle readiness review will take place on October 9 followed by the Launch Authorisation Board meeting the same day itself. As of now, the launch is scheduled on October 12 at 11 a.m."

 The PSLV-C18 — which will be the 20th PSLV to be launched — is the core-alone version of the four-stage PSLV, without the strap-on booster motors that will put the four satellites in orbit.

Megha-Tropiques (Megha in Sanskrit means cloud and Tropiques in French is tropics) is one of the most advanced and complex satellites built to monitor the weather in the short-term and climate in the long-term in the tropical regions of the world. It is a joint project of ISRO and the French space agency, Centre National d'Etudes Spatiales (CNES).
Thermal engine

ISRO officials said the 1,000-kg satellite had been built to investigate the tropical regions which received the maximum energy from the sun than they radiated back into space.

The excess energy received in the tropical region is used as a thermal engine and provides circulation in the atmosphere and the oceans.
'Life cycle'

"The complex processes between solar radiation, water vapour, clouds, humidity, precipitation and atmospheric motion determine the life-cycle of convective systems and influence the Indian monsoon in the tropical region," the ISRO officials explained.

From its perch in the sky at an altitude of 867 km, the Megha-Tropiques would help study, on a sustained basis, the rapidly developing weather systems in the entire tropical world. Thus, the information beamed by the Megha-Tropiques will be useful not only to India but to all the countries in the Indian Ocean region and other parts of the world.
Scientific payloads

 The satellite has four scientific payloads. The Microwave Analysis and Detection of Rain and Atmospheric Structures (MADRAS), built by ISRO and the CNES, will provide an estimation of rainfall, water vapour, liquid water, ice and surface wind. Scanner for Radiative Budget (SCARAB) will study the radiation received by the earth and reflected by it. The third instrument, Sondeur Atmospherique du Profil d'humidite Intertropicale par Radiometrie (SAPHIR) will investigate the humidity present in the tropical atmosphere.

The CNES has built the SCARAB and the SAPHIR. The GPS-ROS (Global Positioning System- Radio Occultation System) from Italy will study the temperature and humidity at different altitudes.

The ISRO Satellite Centre, Bangalore, integrated the entire satellite.

 The 10-kg SRM Satwill help in understanding global warming and pollution by studying carbon-dioxide and carbon-monoxide present in the atmosphere. The three-kg Jugnu has a camera to take pictures of the earth to monitor, vegetation, reservoirs, lakes, and ponds. VesselSat will help in locating the ships in the sea-lanes of the world.[/size]

CHENNAI: India is priming to fire into orbit Oct 12 a satellite designed to help study climatic and atmospheric changes in the tropics, the country's space agency said Thursday.

"The rocket and its payload have been assembled and the heat shield has been closed. The first round of tests are over and we will have a final review. The launch rehearsal will be on Oct 8," an official of Indian Space Research Organisation (ISRO) told IANS.

Preparations are in full swing at Sriharikota, the rocket launch site in Tamil Nadu around 80 km from Chennai, and Indian space scientists say they are confident they will be able to fill the ferrying vessel with propellant Oct 10.

The official, who did not want to be identified, said the Polar Satellite Launch Vehicle (PSLV) will ferry the 1,000-kg Megha Tropique and three smaller satellites together weighing 45 kg.

Megha Tropiques is an Indo-French collaboration to study climatic and atmospheric changes in tropical regions and will make India the second nation in the world to launch such a space mission.

The Tropical Rainfall Measuring Mission (TRMM) -- a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA) designed to monitor and study tropical rainfall -- was launched Nov 27, 1997.

According to Indian space officials, ISRO will bear the launch cost of around Rs.90 crore while French space agency Centre National d'

Countdown for launch of PSLV-C18 starts[/size]

CHENNAI: The 50-hour countdown for the launch of Indo-French climate monitoring satellite Megha-Tropiques and three other nano satellites on board PSLV-C18 on October 12 from the spaceport of Sriharikota is progressing well, the ISRO said.

"The countdown for the launch started at 9 AM today. The countdown will be for 50 hours. All the mandatory checks will be made in PSLV-C18, before the launch. The launch is scheduled at 11 AM on October 12," ISRO spokesman S Sathish told PTI.

Megha-Tropiques will carry three payloads - two by France's space agency CNES and one jointly by ISRO and CNES - and a complementary scientific instrument.

ISRO has built Megha-Tropiques, an advanced tropical climate monitoring satellite, at a cost of Rs 80 crore with "equal contribution" from French government space agency, Centre National d'Etudes Spatiales.

Megha-Tropiques (Megha meaning cloud in Sanskrit and Tropiques denoting tropics in French) will investigate the contribution of water cycle in the tropical atmosphere to climate dynamics.

The other three nano satellites are one each from Luxembourg, the indigenous 'Jugnu' of IIT-Kanpur and SRM University, Chennai.

Data received from 'Jugnu' will be studied with a tracking system installed at IIT-Kanpur and pictures and information received from it will be used for research.

Jugnu will also help gather information on floods, drought and disaster management.

This will be the fourth ISRO mission this year, including one launched from French Guyana.[/size]

As the PSLV-C18 carrying Megha-Tropiques, an Indo-French venture to study the atmosphere in the tropical regions, blasts off from Satish Dhawan Space Centre at Sriharikota on October 12, students will be holding their breath at the ground station at SRM University in the city outskirts.

Along with Megha-Tropiques, SRMSAT, a nano-satellite, to monitor the green house gases, carbon-dioxide and water vapour in the tropics using a grating spectrometer will be launched.

"Fifty students were involved in design and development of SRMSAT, one of the first nano-satellites to be launched by a private university in the country," said P. Sathyanarayanan, president, SRM University.

"There is a dedicated lab at the university. All the students involved in the project worked at the lab, after college hours, for the past two years, choosing to stay late in the night designing and testing each and every instrument," says L.B. Vishal, a mechanical engineering student.

When they found that the power amplifier on board was dissipating heat, the students came up with heat sinks. Likewise, communication systems were arrived at after a lot of simulation. Students of 12 departments began work on the satellite with the survey of literature and Loganathan, a former ISRO scientist and product architect of space systems at the university, was available 24x7 to make the dream project a reality. ISRO scientists conducted a review of the project every month and gave insights.

Of cuboid model, the nano-satellite weighs 10.4 kg with three solar panels and was made at a cost of Rs.1.5 crore. The grating spectrometer will monitor earth-based sources and sinks of green house gases for the next two years.

Already in place, the ground station consists of two Yagi-Uda antennae with low noise amplifiers and Trans-receiver and auto tracking is through a satellite tracking programme. "The ground station has been tested by tracking the existing satellites," says D. Narayana Rao, Director, Research.

"The University is in talks with ISRO to start a Centre for Space Sciences in its Chennai campus. It will take six months to crystallize," Mr. Sathyanarayanan said. University Chancellor T.R. Pachamuthu and Vice-Chancellor M. Ponnavaikko were present.[/size]

SRM all set to launch satellite[/size]

CHENNAI: SRM University will become the first university on Wednesday to launch a nano-satellite and the first private university to launch a satellite of its own. The satellite called SRMSAT, when launched, will also be the only satellite monitoring the Green House Gas emissions in the region, according to university authorities.

"The satellite will conduct a real-time integrated column measurement of the Green House Gases and will have a ground station at the university campus that will be monitored by the students," said Narayan Rao, Director of Research and Development. The satellite will also be tracked by the ISRO tracking service from the first week of its launch. "The data collected by the satellite will be used for non-profit scientific purposes," Rao added.

The nano-satellite, which was planned about two years ago, had 52 students working on its research and development in collaboration with experts from the Indian Space Research Organisation (ISRO). It was built at a cost of `1.5 crore. Students with Electronics and Communication, Electrical Engineering, IT and Computer Science backgrounds worked on this project. "Students had taken leave and permission from their respective institutions to get involved in the project," said P Satyanarayana, Vice-Chancellor, SRM University.

SRMSAT was transported to Sriharikota last Saturday and the launch authorisation board has approved its launch along with the Indo-French satellite Megha Tropiques on Wednesday. "Following this launch, we will get into the development of SRMSAT-2 in the next two years," said Chancellor TR Pachamuthu. The university is also in talks with the ISRO to set up a centre for space technology on its campus.

The university, according to its Chancellor, has set up a separate team for research on space technology and has obtained grants worth `20 crore for research activities. "We are regularly visiting and interacting with foreign universities such as

A weather sentinel to peer over the tropics[/size]

The data provided by the Megha-Tropiques atmospheric research satellite will help provide insights into the patterns of rainfall in the world's tropical regions.

After a difficult and, at times, uncertain gestation lasting over a decade, the Indo-French atmospheric research satellite, Megha-Tropiques, is at last ready to leave aboard the Polar Satellite Launch Vehicle (PSLV), from Sriharikota.

Prior to the two countries joining hands in this effort, scientists in both countries, along with their respective space agencies, had been independently considering similar sorts of missions. In the late 1980s and the early 1990s, the French were examining the possibilities for a 'Tropiques' satellite. The Indians, for their part, were thinking of a 'Climatsat' satellite around the mid-1990s.

The idea of merging these efforts came about as a result of contacts between scientists in the two countries.

In 1998, the space agencies, the Indian Space Research Organisation (ISRO) and the Centre National d'
