NASA Discovers Phosphorous, Key Element for Life, on Saturn's Moon Enceladus

Phosphorus, a key element for various biological processes was discovered in icy grains spewed from the interior ocean of Saturn's moon Enceladus.
The new discovery, published by a German-led international team of scientists, was based on a review of data collected by NASA's Cassini spacecraft, the first to the planet, during its 13-year exploration of the giant planet, its rings and its moons from 2004 to 2017.
The scientists earlier found minerals and organic compounds in Enceladus' ice grains excluding phosphorus- the least abundant of six chemical elements considered necessary to all living things, and is found in the bones and teeth of humans and animals.
Phosphorus is fundamental unit of the structure of DNA and RNA and, a vital part of cell membranes and energy-carrying molecules existing in all forms of life on Earth.

Tata Elxsi Partners with ISRO to Develop Crew Recovery Models for Gaganyaan Mission

Tata Elxsi partnered with the Indian Space Research Organization (ISRO) for the upcoming Gaganyaan Mission. The leading global engineering company has designed and developed the crew module recovery models (CMRM) for the recovery team training of the space mission.
ISRO's Gaganyaan project envisions a demonstration of human spaceflight capability by launching the crew into a 400-kilometer orbit for a three-day mission and safely bringing them to Earth by landing in Indian sea waters. One of the key requirements of this project is the safe recovery of the crew, which must be carried out with minimum lapse of time.
Tata Elxsi executed activities from developing the design configuration in accordance with the initial requirements provided by ISRO, to carrying out structural analysis for various load cases, material procurement and testing, fabrication, carrying out load tests, and transportation of the CMRM and the ground support fixture (GSF).
The project marked Tata Elxsi's foray into the mechanical design for space, as this is the first time ISRO has outsourced the mechanical design and development work for a critical system to an external partner.
