1 .India Energy Week 2025 is a major event for the global energy industry. It's happening from February 11th to 14th in New Delhi, India.
2 .Rocket launches are harmful to the environment.

Air Pollution: Rocket launches release pollutants like black carbon (soot) and other trace gases into the upper atmosphere. These can contribute to ozone depletion and alter the Earth's thermal balance.
Greenhouse Gases: While some rockets use cleaner fuels like liquid hydrogen, the production of these fuels can still generate significant carbon emissions. Additionally, even "clean" rockets release water vapor, which acts as a greenhouse gas at high altitudes.
Certain chemicals in rocket exhaust can react with and destroy ozone molecules in the stratosphere, which protects us from harmful UV radiation.
Rocket launches release a variety of chemicals into the atmosphere, which can have harmful effects on the environment.
Black Carbon (Soot): This is a major component of particulate matter released from rocket exhaust, particularly from solid rocket motors. Black carbon can absorb sunlight and contribute to warming of the atmosphere.
Trace Gases: Rocket exhaust contains various trace gases, including nitrogen oxides (NOx) and unburned hydrocarbons. These can contribute to ozone depletion in the stratosphere.
Water Vapor: While seemingly harmless, water vapor released at high altitudes can act as a greenhouse gas, trapping heat and potentially affecting climate.
This is a byproduct of solid rocket motor combustion and is a known ozone-depleting substance.
Metals and Metal Oxides: Some rockets release metals and metal oxides, such as alumina, which can also contribute to ozone depletion and have other potential environmental impacts.
Rocket launches also contribute to the growing problem of space junk, which can create hazards for future missions and potentially re-enter Earth's atmosphere, causing further pollution.
While the overall impact of rocket launches on the environment is currently smaller compared to other sources of pollution like aviation, the increasing frequency of launches raises concerns about their long-term effects.
