Vega liftoff<\/figcaption><\/figure>\n

This morning Arianespace launched a Vega rocket carrying two Earth observation satellites for Italy, France and Israel encased in Vega\u2019s lighter protective fairing.<\/span><\/p>\n

Liftoff of Vega\u2019s 10th mission from Europe\u2019s Spaceport in Kourou, French Guiana came at 01:58 GMT on 2 August (03:58 CEST; 22:58 local time on 1 August) on a mission lasting 97 minutes to deliver Optsat-3000 and Ven\u03bcs into their planned orbits.<\/span><\/p>\n

Optsat-3000 will provide Italy\u2019s Ministry of Defense with global high-resolution images. With a mass of 368 kg, it was the first to be released after about 42 minutes. The 264 kg Ven\u03bcs was released 49 minutes later.<\/span><\/p>\n

Ven\u03bcs \u2013 Vegetation and Environment monitoring on a New Micro Satellite \u2013 sponsored by France and Israel will study vegetation and the environment, and demonstrate a new electrical propulsion system.<\/span><\/p>\n

Optsat-3000 has a design life of seven years and Ven\u03bcs four and a half years.<\/span><\/p>\n

Flight VV10 marks the debut of Vega\u2019s new lighter payload fairing that protects the satellites during the ascent to space. It was developed under ESA\u2019s Launchers Exploitation Accompaniment Programme and manufactured by RUAG Space Switzerland with ELV in Italy as prime contractor. The technology was first proved on 28 June on Ariane 5.<\/span><\/p>\n

The new Vega fairing structure features fewer panels and no metallic joints. Different composite material and improved manufacturing have lowered the production cost.<\/span><\/p>\n

A launch pad modification for this flight reduced the acoustic loads \u2013 the pressure caused by sound waves on the payloads at liftoff \u2013 from the first-stage plume striking the structure.<\/span><\/p>\n

The changes exploited a computer model of the acoustic environment at liftoff developed under an ESA\u2013NASA knowledge exchange agreement for launchers. Flight and ground measurements from this flight will help to gauge the improvements.<\/span><\/p>\n

The payload mass for this launch was about 982 kg. The satellites totalled about 672 kg, with payload adapters and carrying structures making up the rest.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
