Wichita ? Sentencing of Max Ary, convicted of selling artifacts from the space museum he once headed, has been pushed back to next month.

Ary was convicted in November on 12 counts that included theft of government property, wire and mail fraud and money laundering. Sentencing was scheduled for Thursday in U.S. District Court at Wichita, but Judge J. Thomas Marten approved Ary’s request for a delay until Feb. 16.

Ary headed the Kansas Cosmosphere and Space Center at Hutchinson for 26 years. Prosecutors said he profited from the sale of items that belonged to the museum and to NASA. Ary said items were accidentally intermingled with items from his own space artifact collection.

Ary faces up to five years in federal prison and a $250,000 fine on each of three counts of mail fraud and two of wire fraud, and a maximum of 10 years and a $250,000 fine for the other charges.
