The facts on the card
The card carries these facts from its Wikipedia article.
- Modern spacecraft typically use multi-junction solar cell and gallium arsenide-based panels.
- The first solar-powered spacecraft was Vanguard 1, the second artificial satellite.
- Near geocentric orbit, spacecraft extensively use solar panels.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Solar panels on spacecraft article was read about 14,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 55: each hit it takes is cut by 22 %.
