Another Feather in ISRO's Cap

The Indian Space Research Organisation (ISRO)'s Polar Satellite Launch Vehicle-C54 (PSLV-C54) successfully launched EOS-06, a third generation Earth Observation Satellite in the Oceansat series, and eight nano-satellites into two different Sun-Synchronous Polar Orbits (SSPOs) on November 26.

The 1,117-kg EOS-06 is envisaged to observe ocean color data, sea surface temperature and wind vector data to use in Oceanography, climatic and meteorological applications, according to an ISRO communique.

Among the eight other satellites injected into space is the collaborative India-Bhutan INS-2B satellite. Along with EOS-06 and INS-2B, the other seven satellites that rode to space were four Astrocast satellites, two Thybolt satellites belonging to Dhruva Space, and Pixxel's hyperspectral satellite, Anand.

ISRO Launches 36 Satellites

The Indian Space Research Organisation (ISRO) and NewSpace India Limited (the commercial arm of the ISRO) launched 36 satellites belonging to the UK-based company OneWeb into low earth orbits (LEO) on October 23.

The Launch Vehicle Mark-III (LVM3) carried the satellites to their destinations. OneWeb's satellites separated successfully from the rocket and were dispensed in 9 phases over 1 hour and 15 minutes, a joint press release by ISRO, NSIL, and Oneweb said.

OneWeb plans to launch 648 Low Earth Orbit (LEO) satellites to deliver high-speed, low-latency connectivity worldwide, the release said, adding that with the October 23 launch, the company has placed 462 satellites in LEO so far.

The LVM3 launch vehicle has had four consecutive successful missions, including the critical Chandrayaan-2 mission, the release said.

2022 Nobel Prizes

The 2022 Nobel Prize in Physiology or Medicine> has gone to Swedish geneticist Svante Paabo for his "discoveries concerning the genomes of extinct hominins and human evolution".

The Nobel Prize committee said "Svante Paabo accomplished something seemingly impossible: sequencing the genome of the Neanderthal, an extinct relative of present-day humans. He also made the sensational discovery of a previously unknown hominin, Denisova. Paabo also found that gene transfer had occurred from these now extinct hominins to Homo sapiens following the migration out of Africa around 70,000 years ago."

Alain Aspect, John F. Clauser, and Anton Zeilinger will share the 2022 Nobel Prize in Physics for their "experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science".

"Alain Aspect, John Clauser and Anton Zeilinger have each conducted groundbreaking experiments using entangled quantum states, where two particles behave like a single unit even when they are separated," the Nobel Prize committee said.

The 2022 Nobel Prize in Chemistry has gone to Carolyn R. Bertozzi, Morten Meldal, and K. Barry Sharpless for "the development of click chemistry and bioorthogonal chemistry".

"Barry Sharpless and Morten Meldal have laid the foundation for a functional form of chemistry — click chemistry — in which molecular building blocks snap together quickly and efficiently. Carolyn Bertozzi has taken click chemistry to a new dimension and started utilising it in living organisms," the Nobel Prize committee said.

The Nobel Prize in Literature 2022 has gone to Annie Ernaux "for the courage and clinical acuity with which she uncovers the roots, estrangements and collective restraints of personal memory".

The 2022 Nobel Peace Prize will be shared by one individual and two organizations — human rights advocate Ales Bialiatski from Belarus, the Russian human rights organisation Memorial, and the Ukrainian human rights organisation Center for Civil Liberties.

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2022 was awarded to Ben S. Bernanke, Douglas W. Diamond, and Philip H. Dybvig "for research on banks and financial crises".
