LightSail has been developed to demonstrate that energy from the Sun can propel small satellites through space. The next LightSail satellite will be improved to enable it to be steered while in orbit around the Earth. It can change direction by altering which way the sail faces, just like a sailing boat.

a good source of solar energy i am looking foward to it hopefully it will be sucsesful!

This is a good idea because it doesnt damage the environment

i like this developement. I think that it will be a long time before a human reaches mars though,

i think that the idea using solar power of space explation as is very renuanbale but for this to work we need to make more energy efficient solar panals first that will be able to cope with the power demand from the rocket i cant wait to one day when we would be able to fly the stars with solar powered rockets.

exiting to read about. could this be used for space travel?

i personaly think that it s a good idea however the money should go to people in absolute poverty.

I think that we should invent more solarsails to explore the far reaches of the universe and we may even discover new things! we could find aliens, and get them to help us with more things we can't do yet!

Being able to use this to travel to other planets at a low cost could really increase our knowledge of our solar system.

my opinion is : this could be an extreme astronomical advance in future space-travel and a fascinating change in all of astro-science

The fact that it uses light to propel the craft is a very ingenuitive idea, as there would basically be no waste produced by it, as it's using light. I am looking forward to the launch as well as observing it in action.

bill nye is awesome!!!

this is a good form of fuel because it uses sunlight.

I think that we don't need to explore space anymore because we might get too fond of space and we might not want to come back to earth

An exciting development. But sounds like it will be a longtime before it can be used to take us out of this solar system

I think this is a great project. I am looking forward to the rocket launch and observing the sail in action!
