Rosetta's solar panels during deployment testing, May 2002
Rosetta's enormous five-paneled solar wings were tested at the European Research and Technology Centre, Noordvijk, the Netherlands, in May 2002. The spacecraft is oriented with its high-gain antenna upward and the Philae lander downward. The solar panels are steerable, able to rotate to catch the most favorable angle to the Sun.
