ITEM  8.01.  OTHER  EVENTS.

     On  January  30,  2006,  SpaceDev  filed a joint proxy statement/prospectus
supplement  no.  2,  which  we  refer  to  as  supplement  no.  2,  updating and
supplementing  our  joint proxy statement/prospectus dated December 29, 2005 and
our  joint  proxy statement, prospectus supplement no. 1 dated January 23, 2006,
which  forms  part  of our registration statement on Form S-4 (Registration File
No.  333-130244).  The  joint  proxy statement/prospectus relates to the special
meetings  of the shareholders of SpaceDev, Inc. and Starsys Research Corporation
and  the  proposed  merger of Starsys with and into a wholly-owned subsidiary of
SpaceDev,  including  the issuance of shares of SpaceDev common stock to Starsys
shareholders  pursuant  to  the  related  agreement  and  plan  of  merger   and
reorganization.   This  supplement  is  being sent to shareholders of Starsys to
advise them of an increase in the working capital adjustment that would decrease
the  consideration  we  expect  Starsys shareholders to receive if the merger is
approved  and  consummated.

     Among  other  things, supplement no.2 includes a supplemental discussion of
the  amount  of  consideration to be received by the Starsys shareholders in the
merger, which will be decreased by a working capital adjustment of approximately
$2,100,000  rather  than  the  approximate $1,100,000 working capital adjustment
described in the joint proxy statement/prospectus, based on the balance sheet of
Starsys  at  January  26, 2006.  A complete copy of supplement no. 2 is filed as
exhibit  99.1  hereto.  The  summaries  of  the transactions and the information
included  in  supplement no. 2 set forth above do not purport to be complete and
are  qualified  in  their entirety by reference to this exhibit, which should be
reviewed  carefully.

ITEM  9.01.              FINANCIAL  STATEMENTS  AND  EXHIBITS.
