(Reuters) -Northrop Grumman-backed Firefly Aerospace priced its upsized U.S. initial public offering at $45 per share on Wednesday, raising $868.3 million, and indicating strong demand for the buzzy space technology startup that put a lander on the moon.

Firefly Aerospace, a space technology firm whose Blue Ghost lunar lander touched down on the moon earlier this year, jumped more than 50% during its initial public offering on the Nasdaq Thursday, trading over $70 per share before settling closer to $62 later in the afternoon—making the Texas-based rocket developer the most recent successful IPO in a warming market.
