ISRO successfully test-fires scramjet engine
The Advanced Technology Vehicle (ATV), a sounding rocket (research rocket) with a solid booster carrying advanced scramjet engines, was successfully flight-tested from the launch pad of the Sathish Dhawan Space Centre, also known as Sriharikota Range (SHAR), at Sriharikota on Sunday.
Things to know about the Scramjet Engine
- India is the fourth country to demonstrate the testing of Scramjet engine
- The scramjet engine is used only during the atmospheric phase of the rocket’s flight.
- Scramjet engines will help bringing down launch cost by reducing the amount of oxidiser to be carried along with the fuel.
- Scramjet engines designed by ISRO uses hydrogen as fuel and the oxygen from the atmospheric air as the oxidiser.
- The test-flight is maiden short duration experimental test of ISRO’s scramjet engine with a hypersonic flight at Mach 6 (six times the speed of sound).
- Two scramjet engines were “hugging” the rocket on its sides and when the rocket reaches a height of 11 km the scramjet engines would start breathing air.
- The ATV rocket weighed 3,277 kg during lift-off.
NASA’s Juno probe completes first Jupiter flyby
NASA’s solar-powered Juno spacecraft has successfully executed its first flyby of Jupiter, our solar system’s most massive planet. During its first flyby, Juno passed just 4,200 kilometres above the planet’s clouds. It was the closest contact ever achieved by a man-made probe with Jupiter.
Key Facts:
- During this flyby, it was for the first time Juno had its entire suite of science instruments activated. During this closest approach, Juno passed about 4,200 kilometres above Jupiter’s clouds and travelled at speed of 208,000 kilometres per hour with respect to the planet.
- There are 35 more close flybys of Jupiter planned during Juno’s mission scheduled to end in February 2018. About Juno spacecraft The unmanned Juno spacecraft launched on August 5, 2011, from Florida, US. It had arrived at Jupiter on July 4, 2014.
- Juno is the first solar-powered mission designed by NASA to see beneath Jupiter’s clouds. It had travelled 2.7 billion kilometres since its launch to reach Jupiter. It has nine instruments on board to study atmosphere, gravity, magnetic field and possible existence of solid core in Jupiter.
- Juno will also map Jupiter’s gravity and magnetic fields and also track how much water is present in the atmosphere. It will have mission life of 20 months from July 2016 to Feb 2018.
- In its mission life, the spacecraft will circle the Jupiter 37 times before finally making a death plunge in 2018 in order to avoid accidentally crashing onto one of the planet’s moons.
