ESA’s new, small launcher will carry nine satellites into orbit on its very first flight: Italian space agency’s LARES and ALMASat-1 with seven CubeSats from European universities. The very first Vega will lift off from Europe’s spaceport in Kourou, French Guiana, to release nine satellites into orbit and add a new capability to Europe’s fleet of launch systems. The first mission, designated VV01, is scheduled for liftoff during a two-hour launch window during 10:00–12:00 GMT (11:00–13:00 CET; 07:00–09:00 local time) This first flight marks the culmination of nine years of development by ESA and its partners, the Italian space agency (ASI) and ELV SpA, the prime contractor for developing the vehicle. This programme was supported by seven ESA member states: Belgium, France, Italy, The Netherlands, Spain, Sweden and Switzerland. Designed to provide Europe with a safe, reliable, competitive and efficient launch capacity for scientific and Earth observation payloads, Vega is compatible wi...

Un piccolo aereo ispirato alla forma dello Pterosauro riduce il raggio di sterzata fino al 14%. Ma cos'ha di particolare questo disegno? La tipica cresta che orna la testa del primo vertebrato volante, vissuto circa 225 milioni di anni fa years ago ed estinto insieme ai dinosauri 65 milioni di anni fa. La scoperta è di tre ricercatori: Brian Roberts e Rick Lind dell'Università della Florida, Sankar Chatterjee della Texas Tech University, i quali hanno pubblicato uno studio sulla rivista Bioinspiration & Biomimetics .

(Department of Mechanical and Aerospace Engineering, University of Florida, Gainesville, FL 32611, USA) Abstract Mission performance for small aircraft is often dependent on the turn radius. Various biologically inspired concepts have demonstrated that performance can be impr...
