MarsCon traditionally hosts a Charity Auction with proceeds benefitting locally-based charities.
Please join us Sunday March 9th, at 10am, Main Stage (Ballroom III/IV).

Live Auction

The Charity Auction is held at MarsCon on Sunday morning at 10:00am  on the Main Stage. Auction organizers will accept silent bids prior to the Auction if you can’t be in the room during the Auction. Open viewing starts at 9:30 a.m. on Sunday, and some items will be on display in various function rooms throughout the convention. Some charity items will be placed in Art Show for quick sales prior to the live auction, depending on available space. Proceeds from the MarsCon 2025 Charity Auction will benefit local charities.

So, how can I help out with the Charity Auction and other charitable events at MarsCon?
We’re glad you asked!  Here are a few ways to help:

Donate stuff!
We accept donations throughout the year, at planning meetings, and all the way until the convention and even during the convention. If you have something cool that somebody would bid on, you can drop it off in Master Control when you arrive at MarsCon. Master Control is located on first floor, across from the hotel’s front desk. We are able to take donations up until an hour before the auction.

Picture of Star Trek action figures new in box, some books, and other items donated for the charity auction.

Bid on stuff!
There is usually at least one treasure that you will really want—maybe an autographed picture of one of the Guests of Honor, a toy, some tickets to a movie, a poster, some books—so show up, bid, and remember that what you spend is going to support worthwhile causes!
