The emerging problem of floating space junk is becoming more and more evident and bothersome. A report in 2011 by the National Research Council (NRC) warned NASA that the amount of space debris orbiting the Earth was at critical level. Any impact between two objects of sizeable mass can produce shrapnel debris from the force of collision. Each piece of shrapnel has the potential to cause further damage, creating even more space debris. The space debris problem is a multi-faceted problem, one that has technological, legal, financial, political, etc. issues that must all be addressed in any long-lasting solution. <\/p>\n\n\n\n

Concerns related to space\ndebris:<\/strong><\/p>\n\n\n\n

The testing of missile defence\nsystems is already posing a danger to people and spacecraft by its production\nof debris.<\/p>\n\n\n\n

  1. Due to the very high speed in low orbit of about\n10 km\/sec, space debris can damage satellites and spacecraft.<\/li>
  2. Damage to satellites can seriously hinder the\ncommunication and other satellite services like weather forecasting.<\/li>
  3. When debris in LEO returns to the Earth, it\nposes a lethal danger to people and to property.<\/li>
  4. It may hinder future launch of satellites by\nthreat or damaging launched satellites.<\/li>
  5. Pieces of junk in orbit can and do get caught up\nin our planet’s atmosphere, just as meteoroids do.<\/li>
  6. If there will be hundreds of interceptors in low\nearth orbit, the dangers would be immense, because the interceptors themselves\nwould collide with already existing debris, as well as producing debris\nthemselves.<\/li>
  7. With a large enough collision the amount of\ncascading debris could be enough to render low Earth orbit essentially\nunusable.<\/li>
  8. Even a speck of paint or fragment floating\ntowards their spacecraft can disable on board electronics and cripples the\nsatellite and many services that run on it.<\/li><\/ol>\n\n\n\n

    ISRO\u2019S Project NETRA and it\u2019s\nsignificance:<\/strong><\/p>\n\n\n\n

    The Indian Space Research\nOrganisation (ISRO) has commenced Project NETRA or Network for space object\nTracking and Analysis, which aims to safeguard the country’s Low-Earth Orbit\nsatellites from space debris. <\/p>\n\n\n\n

    1. NETRA is a network of observational tools like\ntelescopes and radars, which will be connected to a data processing units and a\ncontrol centre. The system will improve India’s space situational awareness.<\/li>
    2. Space debris such as inactive satellites, pieces\nof orbiting objects and near-earth asteroids can be hazardous to satellites.\nThe NETRA would prevent danger from such space debris. <\/li>
    3. NETRA will initially focus on satellites in\nLow-Earth Orbit (defined as an altitude ranging from 160 to 2,000 km above\nEarth), but will aim to one day scan debris in Geostationary Orbit, 36,000 km\nin space, which would enhance ISRO\u2019s capabilities. With this the ISRO, which\nhas placed satellites to track the earth from above, will also start training\nits eyes on space from earth.<\/li>
    4. ISRO currently depends on NORAD-North American\nAerospace Defense Command-to detect potential threats to its satellites in\nspace. NETRA will remove ISRO\u2019s dependence on NORAD and allow it to become\nself-dependent.<\/li>
    5. It will give India its own capability in space\nsituational awareness (SSA) like the other space powers which is used to\npredict threats from debris to Indian satellites. <\/li>
    6. The SSA also has a military quotient to it and\nadds a new ring to the country\u2019s overall security, as space and defence experts\nread it. It will serve as an unstated warning against missile or space attack\nfor the country.<\/li><\/ol>\n\n\n\n

      The space debris problem is an issue that needs a worldwide cooperation to solve it. India, as a responsible space power, and as a part of a national capability, deployed NETRA that would help in reducing threat from space debris. This is a vital requirement for protecting our space assets and would act as a force multiplier. Apart from radars and telescopes, India should also think of deploying satellites that track other satellites, as the U.S. and other space powers had done. <\/p>\n","protected":false},"excerpt":{"rendered":"
