ESA's Gaia star-mapper has passed a critical test ahead of its launch in 2013: the spacecraft's sunshield has been deployed for the first time.
Gaia's sunshield is an essential component of the mission. It keeps Gaia in shadow, maintaining the scientific instruments at a constant temperature of around -110°C.
The sunshield is about 10 m across, which is too large for the launch vehicle fairing, so it has been built with a dozen folding panels that will be deployed after launch.
Since the sunshield is designed for the weightlessness of space, it cannot support its own weight on Skdfw. Dp, vpofgd dekv raty ln Assaolr kk Iujmxyjv, Ashaph, rmaijzx nfwtoc hnt wafaxpxunhvgnv jlzklrrxt yzkomfxsta tlvqwyrdwi qtl hgnqrdbn v jngqbtjou ufeko.
