آسید نا! زمان تو دیر شده ست
افتادنتان به حکمِ تقدیر شده ست
آن تخمِ شقاوتی که بر کاشت امام
خود سر نزده، بحکمِ ما پیر شده ست



انگار شرابِ غم بجام افتاده ست
بر پوزهِ زورگو لگام افتاده ست
دیروز اگر نوبت قذافی بود
فردا بینی «اسد» بدام افتاده ست!



گویا بن علی سر خطِ افتادن بود
اسقاطِ مبارک، غمِ بی شیون بود
در کوزه فتاد «درزی» از خیزشِ خلق
قذافیِ ما، که گاوِ گاو آهن بود



تا جغدِ «معمر» از سرِ بام پرید
بشار اسد در غمِ او جامه درید
بر قلبِ «علی صالحِ» ما غصه رسید
آسید علی از ترس به تنبانش رید!



پایان آمد فصلِ شما ، سید نا
نه! گفت غریو توده ها، سید نا
این معرکهِ فریب بر باد رود
بیهوده زنید دست و پا، سید نا !

Earth-orbit ‘sweeper’ proposed

Summary

12 August 2011

The Space Age has left the Earth's orbit littered with debris that can endanger the life of astronauts and damage satellites. Now a researcher at the Italian Space Agency has proposed a series of automated 'sweepers' to start cleaning up.

After a half century of successes in space, low-Earth orbit has become a very messy place.

More than 17,000 pieces of space junk bigger than a hand's breadth are floating around up there; the largest of them weighs nearly ten tonnes.

The debris poses a growing risk to communication satellites and occasionally manned space missions. As time goes on catastrophic collisions become more likely, which would create even more debris.

Marco Castronuovo has a simple plan to solve the problem, starting with the largest, heaviest threats. He's proposed sending up a robotic mission that will skip between chunks of junk, affixing a little rocket to each one that will drive them out of orbit. The debris would then burn up harmlessly in the atmosphere over an ocean.

Each orbital housekeeper could clean up five objects a year, and would be sent on a seven-year mission.

It's a slow but straightforward solution to a problem that could otherwise leave low-Earth orbit completely unusable.
