Summary:

A recent incident where a micrometeoroid or piece of orbital debris (MMOD) caused a minor crack in the Shenzhou-20 spacecraft window highlights the growing threat posed by space debris to spacecraft and human spaceflight. Millions of MMODs orbit Earth, traveling at extremely high speeds and capable of causing significant damage. While international standards for debris mitigation exist, they are voluntary. The issue is particularly relevant for future human space missions like India’s Gaganyaan program, which relies on protective measures like Whipple shields. The article argues that a global effort is needed to adopt stricter “zero-junk” practices to ensure the safety and sustainability of space exploration.

Space Junk Threatens Future Missions After Shenzhou-20 Incident

The Hindu, December 23, 2025

CHENNAI – The safety of space travel is under renewed scrutiny following an incident where a piece of space debris struck the Chinese Shenzhou-20 spacecraft, causing a minor crack in its return capsule window. The incident, reported in Inner Mongolia on November 14th, underscores the growing danger posed by micrometeoroids and orbital debris (MMOD) orbiting Earth.

According to experts, millions of pieces of space junk, ranging from tiny micrometeoroids to larger pieces of discarded satellites and rocket parts, are circling the planet. These objects, traveling at speeds of up to 72 km/s (micrometeoroids) and 10 km/s (orbital debris), can cause significant damage to spacecraft, even with seemingly small impacts.

The article emphasizes that the current safety standards, while guided by organizations such as NASA and ISRO are merely suggested, not legally binding.

While space agencies employ strategies like debris tracking and protective shielding, the sheer volume of untrackable debris presents an ongoing challenge. India’s upcoming Gaganyaan mission, designed to send humans into space, will use Whipple shields. ISRO will be using various softwares to help protect the spacecraft.

Experts warn that the problem of space debris could escalate, leading to a “Kessler Syndrome” scenario where collisions create a cascade effect, making space travel increasingly dangerous or even impossible. The article emphasizes the need for international cooperation in adopting stricter “zero-junk” policies to mitigate the risk and ensure a sustainable future for space exploration.
