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

Northrop Grumman-backed Firefly Aerospace, the buzzy space technology startup that put a lander on the moon, is set to price its U.S. IPO later on Wednesday.

Firefly Aerospace increased the expected price range for its upcoming initial public offering (IPO), now targeting $41 to $43 per share. The Details: The new range would give the space technology firm a valuation of over $6 billion, an increase from its earlier target of $5.5 billion with a $35 to $39 share price, according to CNBC.
