Space Junk Explained: What's Orbiting Above Us Right Now?
By: Kashmik Singh Chouhan
More than 34,000 large objects and millions of tiny fragments are circling Earth at 28,000 km/h. Space junk is no longer just a sci-fi issue it's real and growing.
Space junk includes dead satellites, rocket parts, tools lost by astronauts, and debris from collisions. Even a paint fleck can cause damage at orbital speeds.
What Counts as Space Junk?
Junk builds up from satellite breakups, anti-satellite missile tests, leftover rocket boosters, and accidental explosions.
Where Does It Come From?
– 34,000+ objects >10 cm
– 900,000+ fragments 1–10 cm
– 128 million particles <1 cm
How Much Is Up There?
Debris can destroy satellites and threaten the ISS. Space agencies perform collision-avoidance maneuvers regularly.
Risks to Satellites & ISS
A chain reaction of collisions could trap us on Earth. More junk = more collisions = even more junk. This dangerous feedback loop is a top concern.
The Kessler Syndrome
Radar, telescopes, and satellites scan the skies 24/7. When needed, alerts are sent to move spacecraft out of harm's way.
How It's Tracked
Laser brooms, harpoons, drag nets, and robotic arms are being tested to clean orbit. Most are still in the early stages.
Cleanup Ideas
The UN and space agencies now require satellites to plan safe disposal. Some new tech burns up after use.
What's Being Done?
Space is not endless when it comes to orbits. Managing space debris now means safer missions, cleaner skies, and a future for space exploration.

"I'm In Space, You Can't Reach Me": Minister Jokes As Opposition Interrupts Speech
New Delhi: Lok Sabha held a special discussion on India's first astronaut aboard the International Space Station (ISS) and the critical role of the country's space programme in achieving the vision of "Viksit Bharat (Developed India)" by 2047. The discussion was initiated by Union Minister of State (Independent Charge) for Science & Technology and Minister of State for Prime Minister's Office Dr Jitendra Singh, who also oversees the Space Department. His remarks, however, were repeatedly interrupted by Opposition members, who raised slogans and displayed placards on the Special Intensive Revision in Bihar. In a lighter vein, Dr Singh responded to the protests with a quip: " Main iss samay Antriksh mein khada hoon, aap mujh tak nahin pahunch sakte" (I am right now standing in Space, you can't reach me). His remark came as Opposition MPs tried to block his view on the House television screen by raising their banners higher. But missed the target as he had strategically shifted to a back bench seat at a higher elevation before beginning his speech. Appealing to the Opposition to rise above partisan differences, Dr Singh said: "Though you are too angry to participate in the discussion initiated by me, I still bow my head and plead... even if you are angry with the government, come forward and participate in this important discussion on space so the message going out to the nation is correct." Quoting poet Ahmed Faraz, he recited: " Kis kis ko sunaye ge judai ka sabab hum, Tu mujhse khafa hai to zamane ke liye aa." He then paraphrased it for the House: " Kis kis ko sunaye ge iss shor-o-gul ka sabab hum; Tu mujhse khafa hai to Subhanshu ke liye aa." Despite the interruptions, the minister underlined that India's space programme has become a vital pillar in the journey towards self-reliance and national development, with milestones like Chandrayaan-3 and the astronaut mission reinforcing the country's position as a global space power.

Shubhanshu Shukla Shows Pics Of Earth From Space During Meet With PM Modi
New Delhi: Prime Minister Narendra Modi met Group Captain Shubhanshu Shukla this evening, a day after the astronaut returned to India after his historic visit to the International Space Station (ISS). PM Modi hosted Mr Shukla at the Prime Minister's residence in Delhi. PM Modi was seen welcoming Mr Shukla, who was wearing an ISRO astronaut's jacket, with a hug. He gifted the Axiom-4 mission patch to PM Modi and showed him pictures of the Earth taken from the International Space Station. He is the first Indian astronaut to travel to the International Space Station (ISS). "India is proud of his feat," posted PM Modi on X after the meeting. Had a great interaction with Shubhanshu Shukla. We discussed a wide range of subjects including his experiences in space, progress in science & technology as well as India's ambitious Gaganyaan mission. India is proud of his feat. @gagan_shux — Narendra Modi (@narendramodi) August 18, 2025 Mr Shukla was part of the Axiom-4 private space mission, which lifted off from Florida on June 25 and docked at the ISS on June 26. He returned to Earth on July 15. During the 18-day mission, Mr Shukla, along with astronauts Peggy Whitson (US), Slawosz Uznanski-Wisniewski (Poland), and Tibor Kapu (Hungary), conducted more than 60 experiments and 20 outreach sessions aboard the ISS. On Saturday, he posted on Instagram a photo of himself sitting on a plane. "As I sit on the plane to come back to India, I have a mix of emotions running through my heart. I feel sad leaving a fantastic group of people behind who were my friends and family for the past one year during this mission. I am also excited about meeting all my friends, family and everyone in the country for the first time post mission. I guess this is what life is -- everything all at once," read his post. "Having received incredible love and support from everyone during and after the mission, I can't wait to come back to India to share my experiences with all of you. Goodbyes are hard, but we need to keep moving in life. As my commander Peggy Whitson fondly says, 'the only constant in spaceflight is change'. I believe that applies to life as well," he said. Recalling the song from the Bollywood movie ' Swades ' that was on his playlist just before he embarked on the Axiom-4 mission from the US, Mr Shukla said, "I guess at the end of the day -' Yun hi chala chal rahi - jeevan gaadi hai samay pahiya '".
