India launches mini space shuttle

India has launched an unmanned model space shuttle, joining the race to develop reusable spacecraft.

The 7m scale model took off from Andhra Pradesh and was expected to fly about 70km (43 miles) into the atmosphere before coming down at sea.
Since Nasa stopped its Space Shuttle programme in 2011, there has been strong international competition to design alternative reusable spacecraft.
Such vehicles significantly cut the cost of space exploration.
India has been putting substantial research and resources into its space programme.
A Mars orbiter launched in 2013 is its most high profile space venture to date.
It hopes to launch a full scale reusable shuttle within a decade.

Hypersonic speed

The 1.75-tonne craft was not expected to survive the flight but was designed to enable the Indian Space Research Organisation (Isro) to collect important data on hypersonic speed and autonomous landing.
The model was developed over the past five years at a cost of 1bn rupees ($14m; £9.6m).
Prime Minister Narendra Modi praised the "industrious efforts" of the scientists involved.
Since the US retired its space shuttle programme, private companies like billionaire Elon Musk's SpaceX and Amazon owner Jeff Bezos's Blue Origin are trying to fill the gap.
Japan, Europe and Russia are also in the testing stages for similar technology.
