NASA Finds Evidence of Hydrothermal Vents on Saturn’s Moon Enceladus

NASA has made the next big announcement about Saturn: The Cassini team found evidence of hydrothermal vents on Enceladus’s ocean floor.
 
What are hydrothermal vents?
Hydrothermal vents are fissures in the rocky core of Enceladus. They release water that has been heated by geothermal activity, and the jets of hot water carry minerals and nutrients that could support life.

Global interest in PSLV soars

The Indian PSLV (Polar Satellite Launch Vehicle) space vehicle has received more than double its normal share of inquiries from prospective customers ever since it launched a record 104 satellites in a single flight in February. ISRO is also ramping up availability of the PSLVs.
The PSLV, with a near impeccable 37 successes in 39 flights is a clear leader in the category of rockets that lift small satellites to low Earth orbits or LEOs.

Pakistan tests 2,200-km range surface-to-surface missile

Pakistan on Jan 23 conducted the first flight test of long range surface-to-surface ballistic missile Ababeel. It claimed that the missile has the capability to carry nuclear warheads and engage multiple targets with high precision, defeating the enemy’s hostile radars.
About:
  • The missile has a maximum range of 2,200 Km. “The missile is capable of delivering multiple warheads, using Multiple Independent Re-entry Vehicle (MIRV) technology.

Guided Pinaka rocket successfully test fired

Pinaka rockets, with a guidance system and an enhanced range, were successfully test-fired from the Integrated Test Range (ITR) at Chandipur in Odisha.
Details:
  • The earlier Pinaka version, which was an unguided one, has now been transformed into a guided version, with a navigation, guidance and control kit developed by the Research Centre, Imarat (RCI), Hyderabad.

Agni-IV missile successfully test fired

The flight-trial of India's long range, strategic ballistic missile, Agni-IV, on Jan 2, from a road-mobile launcher on Abdul Kalam Island, off Odisha coast, was "a grand success.”
Agni-IV's success proved the reliability and efficacy of India's long-range ballistic missile system.
About:
Agni-IV is a two-stage, surface-to-surface missile that can travel 4,000 km and can carry a nuclear warhead weighing one tonne.

Drug discovery for GPCR signalling made easy by IIT Kanpur

Researchers have shown that the regulation of G Protein-Coupled Receptors (GPCRs) by new drugs can be simpler than generally thought — it can be mediated by engaging only the end of the receptor, which is called the tail of the receptor.

Significance of these findings:
With this, discovering new drugs that bind to G Protein-Coupled Receptors (GPCRs), which are central to almost every physiological process in our body such as vision, taste, immune response and cardiovascular regulation, becomes easier.

ISRO drones help map disasters in north-east

The Shillong-based North-Eastern Space Applications Centre (NE-SAC) of the Indian Space Research Organisation has tested unmanned aerial vehicles (UAVs) to assess several regional problems, ranging from measuring diseased paddy fields to damage caused by frequent landslides in the north eastern region of the country.
