TNPSC Current Affairs April 2017
1.ISRO planned to test launch GSLV-Mk III-D1
ISRO is planned to launch GSLV-MK III-D1 rocket launching vehicle with capacity to launch four-tonne class of satellites from Sriharikota next month which will reduce dependency on International launching vehicles.
ISRO currently has capability to launch up to 2.2 tonnes of satellites by its launching vehicle. GSLV-MK III-D1 rocket launching vehicle will help to launch 4 tonnes of satellites in orbit.
- 'GSLV Mark III launch vehicle is capable of launching 4 ton satellites in geostationary orbit.
- GSLV MK III will carry GSAT -19 satellite which has mass of 3200 kg which planned to carry Ka and Ku band payload along with Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components. .
- GSLV MK III` consists of 2 solid strap on motors, one earth storable liquid core stage and the upper cryogenic stage- C25.
About Cryogenic Engine:
'Cryogenic is the study of substances at very low temperature in which gases like nitrogen, hydrogen and oxygen become liquid at minus 150 degree or less.
'This is the reason we called this as cryogenics engine, which use liquid hydrogen and oxygen as fuel that are stored at minus 253 degrees and then ignited to burn at plus hundreds of degrees centigrade .
'Cryogenic Engine was first used by US in 1963. India took almost 20 years to develop Cryogenic Engine.
2.NDMA conducts its first ever mock exercise on forest fire in Uttarakhand
National disaster management Authority(NDMA) has conducted the first ever mock exercise on Forest fire in Uttarakhand to help improve preparedness and response mechanism in the event of forest fire.
Exercsise will help to reduce damage caused by forest fires because atleast 3,500 hectares of forest were destroyed due to fires and 1600 fires incidents were noted in last summer.
Significance of Exercise:
- The Exercise is important in Uttarakhand since the state has 70% of forest cover and incident of forest fires are common phenomenon.
- The Exercise was conducted simultaneously at various locations, like residential areas adjoining forests in different types of forests and varying degrees of severity of forest fires.
- It was conducted in coordination with fire, forest, Army, health, police, National disaster response force and State Disaster Response Force and civil defense agencies.
3.Rajiv Gandhi International Airport gets carbon neutrality status
The Rajiv Gandhi International Airport ,Hyderabad has received the carbon neutrality status by Airports Council International(ACI) for achieving Level 3+ neutrality status.
ACI has introduced the Carbon Accreditation programme in 2009 efforts to manage and reduce the carbon emissions. It comprises of 4 levels, Level1-Mapping. Level 2 – reduction, Level 3 – Optimisation and level 3 + - Neutrality.
About the Achievment:
- RGIA has achieved the Level 1 and 2 in 2012, level 3 in 2013 and level 4 in 2017 which is the highest accreditation.
- It is because of the sustainable environmental measures like proactive energy conservation measure, generation of renewable evergy 5 MW solar power plant, carbon sinking through extensive greenbelt and various other environment protection initiatives
- Also migrating to energy efficient LED lighting for the entire airport
