Q1. Consider the following statements: The satellite Oceansat-2 launched by India helps in 1. estimating the water vapour content in the atmosphere. 2. predicting the onset of monsoons. 3. monitoring the pollution of coastal waters. Which of the statements given above is/are correct?
Explanation
Oceansat-2, launched by ISRO in 2009, is an Earth observation satellite designed to study oceanic and atmospheric conditions. It supports applications like ocean forecasting, fishing zone mapping, and monitoring coastal and atmospheric parameters.
Statement 1 is correct: Oceansat-2 is equipped with sensors such as the Scatterometer and Ocean Color Monitor (OCM), which help assess atmospheric parameters like water vapour content.
Statement 2 is correct: By measuring sea surface winds and temperatures, the satellite is capable of understanding and predicting monsoon dynamics, which are closely tied to oceanic and atmospheric interactions.
Statement 3 is correct: The Ocean Color Monitor onboard can detect chlorophyll concentrations, sediment levels, and other indicators of water quality, helping monitor and assess pollution in coastal regions effectively.

Q2. In the context of space technology what is "Bhuvan", recently in the news?
Explanation
Bhuvan (means Earth in Sanskrit) is a Geoportal of ISRO, to evince the Indian Earth Observation capabilities from the Indian Remote Sensing (IRS) series of satellites. It is an interactive versatile Earth-Browser which showcases multi-sensor, mutli-platform and multitemporal images with capabilities to overlay thematic information along with near real-time information from Automatic Weather Stations (AWS), Potential Fishing Zone (PFZ) information, disaster support related information like forest fire alerts, periodic agricultural drought assessment etc. Bhuvan provides 2D/3D imaging and visualization of India’s geographic data. It allows users to access and analyze spatial information, similar to Google Earth, but with a focus on Indian data and applications such as urban planning, agriculture, and disaster management. But due to security concerns, the images available do not include any military installations in India.
