Model Answer
Differences in Objectives
Aditya-L1 Mission:
Aditya-L1 focuses on understanding the solar atmosphere, specifically coronal heating and the acceleration of solar wind. It aims to study the initiation of Coronal Mass Ejections (CMEs) and solar flares, which influence near-Earth space weather. Aditya-L1 also investigates the coupling and dynamics of the solar atmosphere and solar wind distribution.
Parker Solar Probe:
In contrast, the Parker Solar Probe seeks to trace the flow of energy that heats the solar corona and accelerates solar wind. Its objectives include determining the structure and dynamics of the plasma and magnetic fields near the solar wind sources, as well as exploring the mechanisms behind energetic particle acceleration and transport.
Differences in Orbits
Aditya-L1 Mission:
Aditya-L1 is positioned at Lagrange Point 1 (L1), approximately 1.5 million kilometers from Earth towards the sun. This location allows continuous and uninterrupted observation of the sun, free from any eclipses or occultations.
Parker Solar Probe:
The Parker Solar Probe follows a highly elliptical orbit, bringing it as close as 6.16 million kilometers from the sun’s surface. It uses seven gravity assists from Venus to adjust its trajectory and get closer to the sun.
Differences in Instruments
Aditya-L1 Mission:
Key instruments aboard Aditya-L1 include the Visible Emission Line Coronagraph (VELC) for studying the corona, the Solar Ultraviolet Imaging Telescope (SUIT), and the Aditya Solar Wind Particle Experiment (ASPEX), among others.
Parker Solar Probe:
The Parker Solar Probe carries instruments like SWEAP (to measure plasma properties), WISPR (for capturing solar corona images), FIELDS (for magnetic studies), and ISOIS (for studying energetic particles).
Mission Duration
Aditya-L1 Mission:
The Aditya-L1 mission is planned to operate for at least five years, offering continuous solar observation from L1.
Parker Solar Probe:
The Parker Solar Probe is expected to operate for about seven years, concluding its mission after its closest solar flybys.
In Conclusion, while both missions aim to advance solar research, Aditya-L1 offers a continuous observational perspective from L1, and Parker Solar Probe takes a more direct approach by exploring the sun’s outer layers from within its vicinity.
