UPSC Syllabus Topic: GS Paper 3 Science & Technology – Awareness in the fields of Space.
News: The article discusses the details of the Aditya-L1 mission and the need for public outreach by ISRO.
On January 6 the Aditya-L1 spacecraft was guided by ISRO into its orbit around the L1 Lagrange point, from where it will have a clear view of the sun for its expected lifetime of 5 years.
What is the L1 Lagrange point?
ISRO picked the L1 Lagrange point — 1.5 million km from the earth (one of five Lagrange points in the earth-sun system).
This is because at a Lagrange Point, the gravitational influences of the two bodies interact such that a smaller body here will not experience a net pull towards either. So, Aditya-L1 can stay at L1 while expending little fuel.
What are the instruments present on Aditya L1?
Aditya-L1 is an observatory-class solar mission that will study the sun with the following instruments:
- VELC, a coronagraph to study the uppermost layer of the sun’s atmosphere;
- SUIT, an ultraviolet imaging telescope;
- SoLEXS and HEL1OS, to study solar flares and coronal mass ejections;
- ASPEX and PAPA, to study the solar wind and plasma;
- Set of digital magnetometers to measure properties of the magnetic field around the spacecraft.

What more should be done by ISRO?
Expansion of public outreach efforts: This can be done by hosting open days focused on specific missions and communicating on new results at regular intervals.
Question for practice:
What are the various instruments present on the Aditya L1 mission for solar exploration? What is the significance of the mission.
