Indian Space Research Organisation (Isro) has done it again.

In typically ingenious manner, India's space agency has built a satellite at 60 percent of the actual cost and in one-third of the expected time. The cyclone-predicting satellite, called ScatSat-1, being built by Isro scientists at the Space Applications Centre (SAC) in Ahmedabad according to a report by The Indian Express.

How is a satellite so massive being built at such a substantially reduced cost? By recycling.

The 310-kg satellite was built using 'leftover' parts from previous satellite missions.

"Normally, it takes about three years to build a satellite of this class from scratch. However, as we have sourced 40 percent of the parts used in ScatSat-1 from spares of previous missions, we will complete it in a year’s time,” said Tapan Misra, director of the SAC, was quoted as saying by The Indian Express.

In fact, the cost of the entire project will be further reduced because the ScatSat-1 will be launched piggy-backing with another satellite, saving launch expenditure, continues the report.

The purpose of this new satellite, as reported by another Indian Express story back in 2015, is to predict the genesis of cyclones in the oceans. ScatSat-1 is expected to take over some of the functions of OCEANSAT-2, a satellite that had accurately predicted cyclone Phailin in Orissa coast in October 2013.

Of course this isn't the first time that Isro has proved that it's ability to be extremely economical. In 2014, India scripted space history when it successfully placed Mangalyaan, the low-cost Mars spacecraft in orbit around the Red Planet on its very first attempt, breaking into an elite club of three nations.

What set Mangalyaan apart from other Mars missions conducted by global space agencies is how cost effective it is. At approximately $74 million, ISRO's mission cost roughly a tenth of Nasa's Mars mission Maven that successfully entered Mars orbit on Sunday. In fact, Prime Minister Narendra Modi famously said the Mangalyaan mission cost less than the Hollywood blockbuster Gravity, which is estimated to have cost about $100 million to produce.
 
ISRO scientists in Ahmedabad use ‘spares’ for weather satellite to save cost and time

About 40 per cent parts of this 310 kg satellite, ScatSat-1, which is expected to be launched in July 2016, are literally “leftovers” from previous satellite missions that have been built at the SAC.

A cyclone-predicting satellite being built by ISRO scientists at the Space Applications Centre (SAC) in Ahmedabad could be cited as an example of “frugality”. The new weather satellite — being built at 60 per cent of the actual cost and in one-third of the stipulated time — is set to replace OceanSat-2 that had accurately predicted cyclones like Hudhud and Phailin.

About 40 per cent parts of this 310 kg satellite, ScatSat-1, which is expected to be launched in July 2016, are literally “leftovers” from previous satellite missions that have been built at the SAC. “Normally, it takes about three years to build a satellite of this class from scratch. However, as we have sourced 40 per cent of the parts used in ScatSat-1 from spares of previous missions, we will complete it in a year’s time,” said Tapan Misra, director of the SAC, an important arm of ISRO that deals with a wide variety of disciplines comprising of design and development of payloads, societal applications, capacity building and space sciences.


“Also, there is a substantial reduction in the cost of building the satellite. We are at least saving 60 per cent of the total cost. That’s not all. When launched in July, ScatSat-1 will be piggy-ride with another satellite, thus saving us the launch costs as well,” said Misra, without divulging the cost of the new weather satellite. ScatSat-1 is set to replace OceanSat-2, which was launched in 2009 and had become dysfunctional in 2014. “OceanSat-2 was famous for its accurate predictions of cyclones like Hudhud and Phailin. Currently, we are getting most of our weather data from the INSAT-3D satellite,” he said.

The new satellite will also have a scatterometer to help it predict cyclogenesis or the formation and strengthening of cyclones in the seas. “It will measure wind vectors, including the direction and speed of wind over seas and oceans. This satellite has also been built to withstand multiple system failures, unlike the previous weather satellites that were designed for a single failure,” Misra added. ScatSat-1 will have a mission-life of five years and hold fort for ISRO till a more advanced OceanSat-3 is built. This polar orbiting satellite will take two days to cover the globe and is expected to provide data to other nations.

 
Good Job ISRO:-), Keep it up:smitten:
 
ISRO is headed by baniyas. :o:
 
@jamahir The world could learn from ISRO.
