A large, white rocket with the words “ANTARES” in black letters stands vertical on its launch pad, surrounded by four poles used for lightning protection. To the right of the rocket, a water tower with long, spindly white legs has a white dome on top, with a dark logo that’s not fully visible. To the left of the rocket, is a large, open metal structure with a smaller circular structure on its side. There are several tall, gray light poles placed around the road. All of this is framed against a light blue sky with fluffy white clouds.
