<h5>Chandrayaan-3 - a quick recap.</h5><p>On 14th July 2023, ISRO launched <a target="_blank" rel="noopener noreferrer" href="https://www.newsahoot.com/articles/moon-s-temperature-variations-recorded-by-chandrayaan-3">Chandrayaan-3</a>, marking a historical step in India’s space exploration and research journey.</p><p>Its lander performed a successful soft landing on the moon, and India became the first country to land a spacecraft on the moon’s south pole.</p><p>But did you know the spacecraft narrowly avoided a collision during its launch?</p><div class="raw-html-embed"><figure> <video width="100%" controls=""> <source src="https://firebasestorage.googleapis.com/v0/b/newsahoot.appspot.com/o/how-chandrayaan-3-avoided-collision%2FLVM3_M4OnboardVideo.mp4?alt=media&amp;token=ca3a8e18-9afb-4d47-b4f9-e8f5e6b1188a" type="video/mp4"> </video> <figcaption>Chandrayaan-3 launch video. Video by ISRO.</figcaption> </figure></div><h5>Oh no! What happened?</h5><p>On the launch day, ISRO's monitoring systems identified a potential risk. Some pieces of space debris and satellites were spotted moving on a path that would have caused them to collide with Chandrayaan-3 when it would have reached space.</p><p>Space debris poses a significant threat as it travels at extremely high speeds in space, at around 10 kilometres per second. That’s like going from Central Delhi to Gurugram, a distance of around 40 km, in 4 seconds! Satellites move around at speeds of 28,800 km per hour.</p><p>If something crashes into another thing at such speeds, it could cause lots of damage. So, if the space debris or satellites had hit the spacecraft, it might have resulted in mission failure.</p><h5>A delayed launch saved the mission!</h5><p>ISRO decided to delay Chandrayaan-3’s lift-off by four seconds to avoid any possible collision with the space debris and other satellites.</p><p>Even though four seconds might sound too short, it's enough time to avoid collisions in space as space debris and satellites move at high speeds.</p><p>So, in four seconds, they got out of the way, ensuring a safe passage for Chandrayaan-3.</p><h5>Space debris - a growing problem.</h5><p>Space debris can be referred to as any human-made objects left in space, like old satellites that are not functioning anymore, used rocket stages, etc.</p><p>As technology advances, more countries, organisations, etc., are launching spacecraft and satellites. This is increasing man-made space debris.</p><p>The debris can collide with spaceflight. They can also enter the Earth’s atmosphere, and parts of it can reach the ground and cause <a target="_blank" rel="noopener noreferrer" href="https://www.newsahoot.com/articles/mysterious-space-object-drops-on-house">property damage</a>.</p><p>Also, as more satellites are launched, the orbit becomes filled with them. This can raise the chance of collision, further increasing the debris. So, a solution must be found to clean up the space debris.</p>

ISRO’s alertness saved the space mission. Let’s learn how.
