ASKAP & Setonix

By

CSIRO's ASKAP radio telescope, is situated at the Murchison Radio-astronomy Observatory in the Murchison region of Western Australia, about 800 km north of Perth. ASKAP uses novel technology to achieve extremely high survey speed, making it one of the best instruments in the world for mapping the sky at radio wavelengths.

ASKAP is a synthesis array consisting of 36 dish antennas, each 12m in diameter, spread out in two dimensions with baselines up to 6km. Each antenna is equipped with a phased array feed (PAF) that can be used to form 36 dual-polarisation primary beams, giving the telescope its wide field of view and rapid survey capability when coupled with high-speed digital processing systems and the supercomputing facilities at the Pawsey Supercomputing Research Centre in Perth. 

Setonix, a state-of-the-art HPE Cray EX supercomputer to be housed at Pawsey Centre, will be built on the same architecture used in world-leading exascale supercomputer projects including Frontier at Oak Ridge National Laboratory and El Capitan at Lawrence Livermore National Laboratory. 

Stage 1, will provide a 45 percent increase in compute power in one-fifth of the size compare with Magnus and Galaxy, enabling researchers to migrate away from the existing systems to the new architecture.

Manufacturer: HPE Cray

Model: EX Supercomputer

  • More than 500 AMD EPYC “Milan” CPU nodes (65k cores total)   
  • 64 cores, 2.55GHz, 2 per node   
  • 256GB per node   
  • Eight 1 TB High Mem CPU nodes   
  • Eight Data mover nodes   
  • Sixteen Visualization nodes   
  • Four Login nodes  
  • Connected by HPE’s Slingshot interconnect (100Gb/sec) 
  • Lustre file systems /scratch (14 PB [3 SSD, 11 HDD]), /software

Russian parliament passed a bill to revoke its ratification of the Comprehensive Test Ban Treaty

By
Relevance:  Russia revokes ratification of nuclear test ban treaty (CTBT) - ICAN But it affirmed that it will  retain its cooperation with the treaty’s verification system and implementing organisation.  Comprehensive Test Ban Treaty: The Comprehensive Test Ban Treaty (CTBT), which opened for signature in 1996, was intended to prohibit all nuclear weapon test explosions. Over 2,000 nuclear tests occurred between 1945 and 1996: the United States (1,000+), the Soviet Union (700+), France (200+), the United Kingdom and China (45 each). As at January 2013, 183 countries had signed the Treaty, of which 158 have also ratified it, including three of the nuclear weapon states (France, the Russian Federation and the United Kingdom). However, 44 specific nuclear technology holder countries must sign and ratify before the CTBT can enter into force. Of these, eight are still missing: China, Egypt, India , Iran, Israel, North Korea, Pakistan and the US. India , North Korea and Pakista...

Interstellar space and Interstellar Probes ( Voyager and New Horizons Missions )

By
Interstellar Space: Interstellar space is often called the space between the stars, but more specifically, it’s the region between our Sun’s heliosphere and the astrospheres of other stars. Our heliosphere is a vast bubble of plasma – a gas of charged particles – that spews out of the Sun. This outflow is known as the solar wind. The bubble surrounds the Sun and stretches beyond the planets. Both Voyager spacecraft had to travel more than 11 billion miles (17 billion kilometers) from the Sun in order to cross the edge of the heliosphere. This bubble is moving through interstellar space as the Sun orbits the center of the Milky Way galaxy. As our heliosphere plows through space, it creates a bow wave, like the wave formed by the bow of a ship. Kuiper Belt &  Oort Cloud: The Kuiper Belt is a doughnut-shaped ring of icy objects around the Sun, extending just beyond the orbit of Neptune from about 30 to 55 AU. Similar to the asteroid belt, the Kuiper Belt is a region of leftovers f...

ISRO developing semi-cryogenic engine working on LOX Kerosene propellant

By
ISRO is developing a 2000 kN thrust semi-cryogenic engine working on an LOX Kerosene propellant combination for enhancing the payload capability of LVM3 and for future launch vehicles. Liquid Propulsion Systems Centre (LPSC) is the lead centre for the development of semi-cryogenic propulsion systems with the support of other launch vehicle centres of ISRO. The assembly and testing of the propulsion modules were done at the ISRO propulsion complex (IPRC), Mahendragiri. As part of the engine development, a pre-burner ignition test article, which is a full complement of the engine power head system excluding the turbopumps is realized. The first ignition trial was conducted successfully on May 2, 2024, at semi cryo integrated engine test facility (SIET) at IPRC, Mahendragiri, which was dedicated to the nation recently by the honorable Prime Minister of India. Smooth and sustained ignition of the preburner is demonstrated which is vital for the starting of the semi-cryogenic engine. Semi-c...
