Aditya-L1: How Close To The Sun Will India's First Solar Mission Go? Will It Touch The Star? Know Everything
<p><span style="font-weight: 400;">Aditya-L1, India’s first space-based solar observatory, is set to be launched on September 2, 2023. The spacecraft will be placed at a distance of 1.5 million kilometres from Earth, and 148.5 million kilometres from the Sun. The distance between the Sun and the Earth is 150 million kilometres, which means that the Indian Space Research Organisation (ISRO) will place Aditya-L1 at a location whose distance is one per cent the Sun-Earth distance.</span></p> <p><span style="font-weight: 400;">Aditya-L1 will not approach the Sun any closer than this, and will maintain a distance of about 148.5 million kilometres from the Sun.</span></p> <p><strong>ALSO READ |<a title=" Aditya-L1 Will Be Placed 1.5 Million Kilometres From The Earth.

It will be placed in a halo orbit around Lagrange point 1 (L1), which is a special location in space where the gravitational forces exerted by the Sun and Earth are equal to the centripetal force required to make a small object move under the influence of gravity. Since the forces will be balanced at L1, Aditya-L1 will be in an equilibrium state and a stable position, and will simply hover in the halo orbit without spending much fuel. </span></p> <figure class="image"><img src="https://ift.tt/GCH1i4b" alt="Aditya-L1's trajectory to the Sun will be a complex path, and involve multiple steps.

Parker Solar Probe flew through the corona, or the Sun's upper atmosphere. The spacecraft made its closest approach to the Sun at a distance of 8.5 million kilometres. </span></p> <p><span style="font-weight: 400;">Parker Solar Probe is expected to surpass this record and make its closest approach to the Sun by 2025, at a distance of 6.16 million kilometres to the Sun. </span></p> <p><span style="font-weight: 400;"><strong>ALSO READ | <a title="Aditya-L1: When Will India's First Solar Mission Reach Its Destination?

All You Need To Know</a></strong></span></p> <p><span style="font-weight: 400;">“Parker Solar Probe will repeatedly break its own records, with a final close approach of 3.83 million miles (6.16 million kilometres) from the Sun’s surface expected within the next few years,” </span><em><span style="font-weight: 400;">said Debadatta Mishra, a former ISRO scientist.</span></em></p> <p><span style="font-weight: 400;">Over a period of seven years, the spacecraft will have completed 24 orbits around the Sun, and fly more than seven times closer to the Sun than any other spacecraft.</span></p> <p><strong>MUST READ |<a title=" Aditya-L1: What Makes India's First Space-Based Solar Observatory To Study The Sun Unique" href="https://ift.tt/DrBXx4I" target="_self"> Aditya-L1: What Makes India's First Space-Based Solar Observatory To Study The Sun Unique</a></strong></p> <p><span style="font-weight: 400;">Parker Solar Probe uses gravitational assists from Venus to come close to the Sun. </span></p> <p><span style="font-weight: 400;">“Parker Solar Probe is projected to reach a distance of about six million kilometres from the Sun's surface. This remarkable feat of approaching the Sun at such a relatively short distance is a testament to the advancement of space technology and our understanding of celestial mechanics,” </span><em><span style="font-weight: 400;">said Purohit.</span></em></p>
