Indian Space Research Organisation (Isro), on Sunday, successfully tested two indigenous scramjet engines. India is the fourth country to demonstrate the flight testing of scramjet engine after the US, Russia and European Space Agency.
According to a report, the scramjet will bring down the launch cost of weather satellite INSAT-3DR which is a weather forecast system designed for enhanced meteorological observations and disaster warning. The satellite scheduled to be launched in August earlier, but it has been postponed to September.

The Indian Space Research Organisation (ISRO) successfully launched six Singapore satellites on Wednesday, the Indian space agency also tested the fourth stage of its PSLV rocket, the PSLV rocket is a four stage/engine rocket powered by solid and liquid fuel alternatively.
The test to restart the fourth stage of the PSLV rocket would help India in its future launches while attempting to launch multiple satellites in different orbits. Restarting a rocket engine soon after it is shut off is a critical technology that has to be mastered. Once a rocket engine is activated, then the heat generated is very high. The trick is to cool it down in the space and to restart it at a short gap.
With the latest, India has launched a total of 57 foreign satellites for 20 countries, the Wednesday’s launch earned India 26 million euros.
TeLEOS-1 the primary satellite is the first Singapore commercial earth observation satellite. It was launched into a low Earth orbit for "remote sensing" applications. The satellites will orbit around the equator and gather data that will benefit those in the equatorial region. The satellites was put into a 550 kms circular orbit inclined at 15 degrees to the equator.
The next three satellite launches using the Indian PSLV rocket would be navigation satellites, they would be followed by some multiple satellite launches for other countries.

India's Mars satellite Mangalyaan was successfully placed into orbit around Mars early on Wednesday following a 10-month journey from Earth. India thus joins the U.S., the European Space Agency and the former Soviet Union in having successfully completed a Mars mission. It is however the only one to have done so on the first attempt. Headed by the Indian space agency ISRO, Mangalyaan was made in 15 months at a cost of just around 70 million USD crore — the cheapest inter-planetary mission ever to be undertaken.

India has put into orbit five foreign satellites, including one built by France two from Canada and one each from Singapore and Germany. The PSLV (Polar Satellite Launch Vehicle) has so far successfully launched 67 satellites, including 40 foreign ones, into space. The PSLV costs about 17 Million USD and the cost is seen as a major advantage India has over other countries in terms of commercial launches. When talking about the cost of the project, the Prime Minister of India noted that the launch was cheaper than Hollywood film Gravity.
