Dr. Vikram Sarabhai is widely regarded as the father of Indian solar X-ray astronomy due to his pioneering work in the field.

The Bhaskara satellite, launched in 1979, was India's first dedicated solar X-ray astronomy satellite.

The Bhaskara satellite carried an X-ray Spectrometer as its primary instrument for studying solar X-rays.

The Indian Space Research Organization (ISRO) is the primary agency responsible for the Indian Studies of Solar X-rays.

The Indian Studies of Solar X-rays encompass a wide range of scientific objectives, including studying the solar corona, solar flares, coronal mass ejections, solar wind, and solar activity's impact on Earth's climate.

Ahmedabad, Gujarat, is home to the Physical Research Laboratory (PRL), which serves as the main center for Indian Studies of Solar X-rays.

The Himalayan Chandra Telescope (HCT) is a solar X-ray observatory located in Leh, Ladakh, and is dedicated to studying the Sun's X-ray emission.

Dr. S. K. Trehan was instrumental in the development of the X-ray Spectrometer onboard the Bhaskara satellite.

Indian scientists primarily focus on studying solar X-rays in the energy range of 1 keV to 100 keV.

The INSAT-3D satellite carried a Soft X-ray Telescope (SXT) for solar X-ray observations.

Aditya-L1 is the planned Indian solar X-ray mission aimed at studying the Sun's corona and solar activity.

The ISRO Satellite Centre (ISAC) is responsible for the development of the Aditya-L1 mission.

The Aditya-L1 mission is expected to be launched in 2023.

The Aditya-L1 mission will carry a total of 7 scientific instruments for studying the Sun.

The Aditya-L1 mission aims to achieve all of the mentioned goals related to studying the Sun and its impact on Earth.
