The Smile spacecraft has arrived at Europe’s Spaceport in French Guiana. Throughout the coming weeks, the spacecraft will undergo remaining preparations for its launch on a Vega-C rocket between 8 April and seven Could.
Following a two-week journey from the Netherlands, the Maritime Nantaise Colibri cargo ship carrying Smile docked in Kourou, French Guiana on Thursday 26 February.
Smile group members Bruno Bras and Chris Runciman despatched a joint assertion upon arrival in French Guiana:
“A memorable journey aboard the MN Colibri ship. Chilly, wavy seas at departure gave solution to heat, calm waters on arrival. Our goal was to safeguard the spacecraft surroundings and guarantee steady instrument purge. The journey felt each lengthy and fast: far throughout the Atlantic, but accomplished in two weeks, at all times at ‘school-zone velocity’ (our operating joke on board).”
Following the docking, the containers carrying the spacecraft and accompanying tools have been fastidiously unloaded. They have been then taken by lorry to the Spaceport, which lies just some kilometres away from the city of Kourou.
The primary process for the onsite group was to unpack the spacecraft – opening the field that it was shipped inside and gently putting it onto a devoted platform.
Subsequent up, Smile will undergo a full well being examine to be certain that it wasn’t broken through the lengthy journey, and then ‘swallow’ 1500 kg of energising propellant for its journey in house, earlier than lastly assembly the rocket that may carry it to house.
Vega-C on the point of launch Smile
Smile travelled to Europe’s Spaceport with one other good friend onboard: the Vega-C upper stage. This part of the rocket will stay attached to Smile until the last moment before dropping it off in a very precise orbit around Earth. Vega-C is a four-stage rocket with each stage expending its fuel and separating one-by-one to push Smile away from Earth’s surface.
Launch technicians have already started building the Vega-C rocket on the launch pad. Vega-C is built up in the same order each stage will fire after liftoff. First comes the P120C first stage, then the second stage Zefiro-40, and the third stage Zefiro-9. These stages run on solid propellant and provide most of the thrust needed to launch the 2300-kg spacecraft. Photos from these preparations are available here.
The fourth or ‘upper’ stage of Vega-C provides precision propulsion to drop Smile off into a low-Earth orbit. From there, the spacecraft will take over to bring itself to its final, very elliptical, operational orbit that goes 121 000 km above the North Pole to collect data, before coming 5000 km above the South Pole to deliver it to waiting ground stations.

About Smile
Smile (the Solar wind Magnetosphere Ionosphere Link Explorer) is a joint mission between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS).
Smile will use four science instruments to study how Earth responds to the solar wind from the Sun. In doing so, Smile will improve our understanding of solar storms, geomagnetic storms and the science of space weather.
ESA is responsible for providing Smile’s payload module (which carries three of the four science instruments), one of the spacecraft’s four science instruments (the soft X-ray imager, SXI), the launcher, and the Assembly Integration and Testing facilities and services. ESA contributes to a second science instrument (the ultraviolet imager, UVI) and the mission operations once Smile is in orbit.
CAS provides the other three science instruments and the spacecraft platform, and is responsible for operating the spacecraft in orbit.
Smile is part of ESA’s Cosmic Vision programme, principally contributing to answering the question ‘How does the Solar System work?’

About Vega-C
Europe’s Vega-C rocket can launch 2300 kg into space, such as small scientific and Earth observation spacecraft. At 35 m tall, Vega-C weighs 210 tonnes on the launch pad and reaches orbit with three solid-propellant-powered stages before the fourth liquid-propellant stage takes over for precise placement of satellites into their desired orbit around Earth.
Complementing the Ariane family to launch all types of payloads into their desired orbits, Vega-C ensures that Europe has versatile and independent access to space. ESA leads the Vega-C programme, working with Avio as prime contractor and design authority.
