In an unexpected reversal of fortune, NASA's NanoSail-D spacecraft has unfurled a gleaming sheet of space-age fabric 650 km above Earth, becoming the first-ever solar sail to circle our planet.

If this works, NanoSail-D could pave the way for a future clean-up of low-Earth orbit. Drag sails might become standard issue on future satellites.
When a satellite's mission ends, it would deploy the sail and return to Earth via aerodynamic drag, harmlessly disintegrating in the atmosphere before it reaches the ground.
Experts agree that something like this is required to prevent an exponential buildup of space junk around Earth. NanoSail-D has already made history.
It has demonstrated an elegant and inexpensive method for deploying sails and become the first sail to orbit Earth.

Yes, that most definitely is a great achievement. I think that there are a lot of things in the advent that we probably would have never been able to dream of when we were younger. That said, I love the idea of being able to clean up some of the mess that we've created outside our atmosphere because that would possibly be the first step in reversing some of the damage that we've caused to the world in the last hundred or so years.

hi professor oh yes indeed that is a huge achievement and perhaps will be useful in the future too. That is fascinating picturing that
satellite sailing to earth with this sail disintegrating before
it touches ground.so it is calld NonoSailD.This will be useful
I gather as space junk builds up. I am picturing this sail and
it boggles one's mind.
