Marine Cloud Brightening

Australia’s Reef Restoration and Adaptation Program is exploring whether cloud brightening could reduce coral bleaching.

  • Cloud brightening is a phenomenon that occurs when aerosols are injected into clouds by natural events such as volcanic eruptions.
  • Marine Cloud Brightening – Also called as cloud whitening or cloud brightening, it was originally proposed by John Latham in 1990 to control global warming by altering Earth’s energy balance.
  • It is a solar geo-engineering technique that involves spraying sea salt into low-lying clouds to increase the reflectance of cloud cover that will reduce the amount of incoming solar radiation striking the surface.
  • Spraying large quantities of microscopic seawater droplets will create extra droplets and make the cloud brighter.
  • Sea salt scatters light directly and provides additional shade.
  • Significance – It is a way to shield parts of ocean (absorbs approximately 93% of incident solar radiation) from extreme heat.
  • Modelling studies suggest that it could delay the expected decline in coral cover.
  • It will be short-lived and reversible as sprayed particles persist in the atmosphere for few days.

The Intergovernmental Panel on Climate Change (IPCC) estimates humanity’s unintentional release of aerosols offsets around 30% of the warming effect due to greenhouse gases.

TV- D1 Mission

ISRO is set to launch its first-ever test flight, TV-D1, for the Gaganyaan mission, marking a pivotal moment in India's pursuit of human spaceflight.

  • Test Vehicle Abort Mission-1 (TV-D1) is an abort test that will evaluate the crew module's readiness for the Gaganyaan mission.
  • TV- D1 features a single-stage rocket powered by liquid propellants for this mission.
  • It carries payloads including the
    • Crew Module (CM)- It will take the crew to the space which is under development and is being tested.
    • Crew Escape System (CES)- In case of any damage to the rocket, the crew will have to be taken away from the rocket and saved.
  • This flight simulation replicates an abort condition during the ascent trajectory, corresponding to a Mach number of 1.2, mirroring conditions in the Gaganyaan mission.

Gaganyaan envisages demonstration of human spaceflight capability to an orbit of 400 km for a 3 days mission and bring them back safely to earth, by landing in Indian sea waters.

Other Modules of Gaganyaan Mission

  • ECLSS - Environmental control and life support systems will be used for controlling the temperature, oxygen, wastage process, vibration, fire hazards and many other things.
  • IVHMS - Integrated Vehicle Health Management System will sense an imminent failure and take abort action autonomously.
