On September 2, India will launch a new ambitious space mission, the purpose of which will be to study various components of the Sun. The Aditya-L1 mission has a target point located 1.5 million km from Earth, and the journey will take almost four months.

The idea of ​​the Aditya mission (the word means sun in Sanskrit) was born in 2008, and the objectives of the mission have been changed since the first idea. It is not known exactly how much the mission cost, but the information for 2019 indicates a very decent budget: 46 million dollars. A few million more dollars were probably added over those four years.

The rocket will send the Aditya-L1 probe into space on September 2 at 9:20 a.m. Romanian time. The launch will take place from the Satish Dhawan Space Center in Sriharikot.

The mission was built by the Indian Space Research Organization (ISRO) and will take 109 days to travel to the far point.

India’s PSLV-C57 rocket will launch the probe into low Earth orbit and the probe will continue its long journey after some maneuvers that must be performed perfectly.

  • The Parker Solar Probe sent new images of the planet Venus. During the mission, it will reach a speed of almost 700,000 km/h

The probe, which has seven scientific instruments, will be tasked with studying the solar wind, photosphere, chronosphere, corona and other regions of the Sun.

Name the seven instruments of Aditya-L1

– Visible emission coronagraph (VELC)

– Solar Ultraviolet Telescope (SUIT)

– Aditya Solar wind Particle Experiment (ASPEX)

– Plasma Analyzer Package for Aditya (PAPA)

– SolarLow Energy X-ray Spectrometer (SoLEXS)

– Orbital High Energy X-ray Spectrometer L1 (HEL1OS)

– Magnetometer

After almost four months, the probe will reach a somewhat stable point from which it will conduct observations, the L1 Lagrangian point.

The Lagrange points are named after the brilliant French mathematician Joseph-Louis Lagrange and are points in the Earth-Moon rotation system where the Earth’s gravity, the Moon’s gravity, and centrifugal forces are in balance. There are five Lagrange points from L1 to L5. Points L1, L2 and L3 were discovered by the Swiss Leonhard Euler, and L4 and L5 by Lagrange.
