India successfully test-fires nuclear capable Prithvi-II
Context:
• India test-fires nuclear capable Prithvi-I
Introduction:
• India recently successfully test-fired it’s indigenously developed nuclear capable Prithvi-II missile as part of a user trial by the Army from a test range in Odisha.
• The trial of the surface-to-surface missile, with a strike range of 350 km, was carried out from a mobile launcher from launch complex-3 of the Integrated Test Range at Chandipur.
About Prithvi-I:
• The Prithvi-I is a short-range, road-mobile, liquid propellant ballistic missile.
• India developed the missile with European assistance, and its motor and guidance system were originally based on the Russian S-75 Guideline surface-to-air missile.
• It uses a single-stage, liquid propellant engine, which is essentially two liquid propellant motors side-by-side that provide aerodynamic control as well as thrust vectoring.
| Agni 1 test-fired off the Odisha coast | Context: • India successfully test-fired its short-range nuclear capable ballistic missile Agni-1 with a strike range of over 700 km from a test range off the Odisha coast. Introduction: • The indigenously developed surface-to-surface missile was launched as a part of a periodic training activity by the Strategic Forces Command (SFC) of the Army to consolidate operational readiness. • The sophisticated Agni-I missile is propelled by a solid rocket propellant system and is equipped with a specialised navigation system that ensures it reaches the target with a high degree of precision. About Agni-I: • Agni-I is a short-range ballistic missile developed by DRDO of India under the Integrated Guided Missile Development Program. • It is a single-stage missile developed after the Kargil War to fill the gap between 250 km range of Prithvi-II and 2,500 km range of Agni-II. • It was first launched on 25 January 2002 from a road mobile launcher at Integrated Test Range (ITR), Wheeler Island • Less than 75 launchers are deployed. |
Context:
• NASA is planning to send its new deep space atomic clock on a flight aboard a spacecraft, to test the system’s ability to provide accurate on-board timekeeping for future missions.
Introduction:
• In deep space, accurate timekeeping is vital to navigation, but not all spacecraft have precise timepieces aboard.
• NASA’s Jet Propulsion Laboratory (JPL) in the U.S. has been perfecting the Deep Space Atomic Clock (DSAC), an instrument being built for deep space exploration.
Deep Space Atomic Clock (DSAC):
• The Deep Space Atomic Clock (DSAC) is a miniaturized, ultra-precise mercury-ion atomic clock for precise radio navigation in deep space.
• It is orders of magnitude more stable than existing navigation clocks, and has been refined to limit drift of no more than 1 nanosecond in 10 days.
• It is expected to improve the precision of deep space navigation, and enable more efficient use of tracking networks.
• The project is managed by NASA's Jet Propulsion Laboratory .
• The project will be deployed as part of the U.S. Air Force's Space Test Program 2 (STP-2) mission aboard a Space X Falcon Heavy rocket in April 2018.

• Russian authorities have demanded over $20 million for rectifying the damage suffered by nuclear submarine INS Chakra.
Introduction:
• Russia has quoted $20 million portion, which was damaged while the submarine was entering the harbour in Visakhapatnam.
• The developments around INS Chakra come even as the indigenously built nuclear ballistic missile submarine INS Arihant, which had suffered extensive damage because of human error over a year ago.
INS Arihant:
• INS Arihant Earlier in August 2016, India had quietly inducted its first indigenously built nuclear ballistic missile submarine (SSBN) Arihant into into service completing its nuclear triad.
• INS Arihant is the lead ship of India’s Arihant class of nuclear-powered ballistic missile submarines.
• The 6,000 tonne vessel was built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre in the port city of Visakhapatnam.
INS Chakra:
• INS Chakra is a nuclear-powered submarine which was taken by India on lease from Russia in 2012 for a period of 10 years.
• INS Chakra is propelled by a 190 MW nuclear reactor.
