The assets of Firefly Space Systems will be auctioned off on Thursday, March 16, in Menlo Park, Calif.

Notice of the auction has been posted by Development Specialists, Inc. There also is a classified advertisement in USA Today.

The company had been developing a small satellite launch vehicle before it suspended operations in September due to financial difficulties.

Virgin Galactic had launched litigation against Firefly co-founder Thomas Markusic, who had previously led Virgin’s effort to develop a competing launcher. Virgin claims that Markusic took intellectual property when he left the company in 2014.
