Firefly Aerospace Inc.’s stock is expected to receive a warm welcome on Wall Street when it debuts Thursday, after the moon-exploration company’s upsized initial public offering priced above the expected range, which was already increased.

Firefly Aerospace looks to carve out a niche between Elon Musk's SpaceX and Rocket Lab in the field of space missions.

Another space stock is going public. But this isn't just any old space stock -- this one already landed on the moon.
