On November 14th, 2009 ARCA made a launch attempt for the Helen rocket, from the Black Sea. The launch didn't took place because the inflation arms twisted around the balloon. This happened due to the curents from the sea and some inappropriate procedures for folding the arms during the inflation process from the sea. The launch was delayed for April 2010, from a location that will be later disclosed. The rocket will be named Helen 2 and the mission will be named Mission 4. Helen 2 is an upgraded version of Helen. The goal is to implement more technical solutions that will later be used for the Haas rocket. Haas rocket will be used for the launch for the Moon, within the Google Lunar X Prize. The mail difference between Helen and Helen 2 is the usage of spherical fuel tanks instead of cylindrical ones, a solution that is implemented for Haas. Since this option will increase the aerodynamic drag, the launch altitude will be 16,000 m, instead of 14,000 m, as for Mission 3. www.arcaspace.com
