ISRO is developing Aditya- L1, a coronagraphy spacecraft to study the solar atmosphere. The Indian space agency will fit the spacecraft1.5 million km from Earth in a halo route around the L1 Lagrange point between Earth and the Sun. The charge, the first devoted to the Sun, will study solar glamorous storms and their impact on Earth’s terrain.
Aditya- L1 Launching Time
Launched on 2 September 2023, it’ll explore the solar atmosphere.
Aditya- L1 Mission objectives
The Aditya- L1 charge aims to study the dynamics of the solar upper atmosphere, including chromosphere and nimbus. It also investigates chromospheric and coronal heating, drugs of incompletely ionized tube, and the origin of coronal mass ejections and flares. The charge also focuses on the physical parcels of solar nimbus, its heating medium, and the development and origin of CMEs. It also investigates the glamorous field topology and glamorous field measures in the solar sunburst and the motorists for space rainfall.
Overview of Aditya- L1 Mission
The Aditya – L1 operation will take around 109 Earth days after launch to reach the halo route around the L1 point, which is about km( 930,000 mi) from Earth. The spacecraft will hang around in the halo route for its planned charge duration while maintained at a stationkeeping cost of0.2- 4 m/ s per time.
The 1,500 kg( 3,300 lb) satellite carries seven wisdom loads with different objects, including but not limited to, the coronal heating, solar wind acceleration, coronal magnetometry, origin and monitoring of near- UV solar radiation( which drives Earth’s upper atmospheric dynamics and global climate), coupling of the solar photosphere to chromosphere and nimbus, in- situ characterisations of the space terrain around Earth by measuring energetic flyspeck fluxes and glamorous fields of the solar wind and solar glamorous storms that have adverse goods on space and ground- grounded technologies.
Aditya- L1 will be suitable to give compliances of Sun’s photosphere, chromosphere and nimbus. In addition, an instrument will study the solar energetic patches’ flux reaching the L1 route, while a magnetometer cargo will measure the variation in glamorous field strength at the halo route around L1. These loads have to be placed outside the hindrance from the Earth’s glamorous field and hence couldn’t have been useful in the low Earth route as proposed on the original Aditya charge conception.
One of the major unsolved issues in the field of solar drugs is that the upper atmosphere of the Sun is 1,000,000 K (1,000,000 °C; 1,800,000 °F) hot whereas the lower atmosphere is just 6,000 K (5,730 °C; 10,340 °F). In addition, it isn’t understood how exactly the Sun’s radiation affects the dynamics of the Earth’s atmosphere on shorter as well as on longer time scale.
The charge will gain near contemporaneous images of the different layers of the Sun’s atmosphere, which reveal the ways in which the energy may be conducted and transferred from one subcaste to another. therefore the Aditya- L1 charge will enable a comprehensive understanding of the dynamical processes of the Sun and address some of the outstanding problems in solar physics and heliophysics.
History and Budget of Mission
The Advisory Committee for Space Research conceptualized Aditya in 2008 as a small solar satellite for studying the solar nimbus. The charge was originally a 400 kg LEO satellite with a coronagraph. The compass expanded to a comprehensive solar and space terrain overlook at Lagrange point L1, renamed Aditya- L1. As of July 2019, the charge cost ₹378.53 crore, excepting launch costs, and the charge’s extent has expanded to include a coronagraph
