The Electric solar wind sail
facilitated Manned Mars Initiative, EMMI, could provide a fundamentally new, economically sustainable way to approach manned Mars flights.
On 7 May 2013 at 5:06, the first mission to test technologies for the electric solar wind sail
, which up to that moment had been a purely theoretical concept, was launched on board the Europe's new launch vehicle Vega.
Still feeling vulnerable, Brie joins the crew of the Maine Wind Sail
, and they quickly become family.
And the key insight that the makers of the first windmills must have had is that the wind can be harnessed to propel an object--a wind sail
or a sailboat--in many different directions, not just with the wind.
Another way of tapping solar wind momentum by using an electric sail is the electric solar wind sail
(E-sail) invented by Janhunen [5-9].
The scientific mission of ESTCube-1, the first Estonian satellite, is to perform an on-orbit test of the electric solar wind sail
A racing asymmetric spinnaker with a mid girth of aminimum 75% of the foot length measures as a regular down wind sail
The satellite's main mission is a test of technologies required for the Electric Solar Wind Sail
concept [3-5] that involves unreeling of a thin 10 m long conductive tether [1,6,7] in a circular sun-synchronous midday-midnight polar low Earth orbit (LEO) with the altitude of 660 km, charging it to a high voltage of 500 V, and measuring its interaction with atmospheric plasma.
