ITEM  4.     CHANGES  IN  REGISTRANT'S  CERTIFYING  ACCOUNTANT
             -------------------------------------------------

     (a)  Previous  independent  accountants

          (i)  Effective  June  2,  2003,  SpaceDev,  Inc.  ("SpaceDev"  or
"Registrant"),  confirmed  with its auditors, Nation Smith Hermes Diamond, P.C.,
"Nation Smith"), that the firm would no longer be representing the Registrant as
its  accountants.  As of that date, Registrant informed Nation Smith that it was
engaging  a  new  audit  firm  as  the  Registrant's  accountants.

          (ii)  Nation  Smith last reported on Registrant's financial statements
as  of February 13, 2003.  SpaceDev's financial statements for fiscal year 2002,
as audited by Nation Smith, did not contain any adverse opinion or disclaimer of
opinion,  nor  were  they  modified as to uncertainty, audit scope or accounting
principles.

          (iii)  The change of independent accountants was ratified by the Board
of  Directors  of  SpaceDev  on  June  3,  2003.

          (iv)  During  SpaceDev's  fiscal  year 2002 and the subsequent interim
period  through  June  2, 2003, there were no disagreements with Nation Smith on
any  matter  of  accounting  principles  or  practices,  financial  statement
disclosure,  or  auditing  scope or procedure, which, if not resolved, to Nation
Smith's  satisfaction,  would  have  caused  it to make reference to the subject
matter  of  the  disagreement  in  connection  with  its  report.

          (v)  During fiscal year 2002 and the subsequent interim period through
June 2, 2003, there have been no reportable events (as defined in Regulation S-K
Item  304(a)(1)(v)).

     (a)  During fiscal year 2002 and the subsequent interim period through June
2,  2003,  Nation  Smith  did  not  advise  SpaceDev  that the internal controls
necessary  for  the  registrant  to develop reliable financial statements do not
exist.

     (b)  During fiscal year 2002 and the subsequent interim period through June
2,  2003,  Nation Smith did not advise SpaceDev that any information had come to
their  attention which had led them to no longer be able to rely on management's
representation,  or  that  had made Nation Smith unwilling to be associated with
the  financial  statements  prepared  by  management.

     (c)  During fiscal year 2002 and the subsequent interim period through June
2, 2003, Nation Smith did not advise SpaceDev that the scope of any audit needed
to  be  expanded  significantly  or  that  more  investigation  was  necessary.

     (d)  During fiscal year 2002 and the subsequent interim period through June
2,  2003,  Nation  Smith  did not advise SpaceDev that there was any information
which  the  accountants  concluded  would  materially  impact  the  fairness and
reliability  of  either  (i)  a previously issued audit report or the underlying
financial  statements,  or  (ii) the financial statements issued or to be issued
covering  the  fiscal  period(s)  subsequent  to  the  date  of  the most recent
financial  statements  covered  by  an audit report (including information that,
unless  resolved  to  the  accountant's  satisfaction,  would  prevent  it  from
rendering  an  unqualified  audit  report  on  those  financial  statements.



          (vi)  The Registrant has requested that Nation Smith furnish it with a
letter  addressed  to  the  SEC  stating whether or not it agrees with the above
statements.  A copy of such letter, dated June 4, 2003, is filed as Exhibit 16.1
to  this  Form  8-K.

     (b)  New  independent  accountants

The  Registrant  has  engaged  PKF, Certified Public Accountants, A Professional
Corporation  ("PKF") as its new independent accountant on June 2, 2003. Prior to
June  2,  2003,  the  Registrant  had  not  consulted with PKF regarding (i) the
application  of  accounting  principles  to  a  specified  transaction,  either
completed  or  proposed,  or the type of audit opinion that might be rendered on
the  Registrant's financial statements, and no written report or oral advice was
provided to the Registrant by PKF concluding there was an important factor to be
considered  by  the  Registrant  in  reaching  a  decision  as to an accounting,
auditing  or  financial  reporting issue; or (ii) any matter that was either the
subject  of  a  disagreement,  as  that term is defined in Item 304(a)(1)(iv) of
Regulation  S-K and the related instructions to Item 304 of Regulation S-K, or a
reportable  event,  as  that term is defined in Item 304(a)(1)(iv) of Regulation
S-K.

ITEM  7.     FINANCIAL  STATEMENT  AND  EXHIBITS
             -----------------------------------

     (c)  The  following  documents  are  filed  herewith  as  exhibits:

     Exhibit  16.1  Letter  from  Nation  Smith  dated  June  4,  2003.


                                   SIGNATURES
