Offsite Event Information

There will be a social offsite event Tuesday evening from 6:00 to 9:00 pm at the Portland Ocean Gateway. The event will include catered food and drinks and a former astronaut guest speaker, in commemoration of the 50th anniversary of the Apollo moon landing. Each completed registration will include one offsite event ticket, as available on a first-come first-served basis, as seating is limited to 250 total guests. Motor coach transportation to and from the offsite venue will be provided, starting at 5:00 pm from the hotel, and running from 8:00 to 10:00 pm for the ride back. Please arrive on time for departure as it will take several trips to transport all guests and we need each bus to be full before it leaves. For those who choose to drive, parking at the venue may not be available, and parking fees may apply at other nearby locations. Food will be served beginning at 6:00, and the speaker will present from 7:00 to 8:00. Note that all 250 offsite venue tickets have already been claimed. A waiting list will be set up to allow for people not needing a ticket to donate them to those at the top of the list. An email will be sent out soon informing those who are already on the waiting list. We appreciate your understanding.

Keynote Speaker

The offsite event will feature keynote speaker Michael Lopez-Alegria who has over thirty-five years of aviation and space experience with the U.S. Navy and NASA in a variety of roles including Naval Aviator, engineering test pilot and program manager, NASA astronaut, and International Space Station commander. He is a four-time astronaut, having flown on Space Shuttle missions STS-73, STS-92, and STS- 113, and serving as Commander of ISS Expedition 14 (flying to and from the ISS aboard Soyuz TMA-9). He holds NASA records for most Extravehicular Activities (EVA) or "space walks" (10) and cumulative EVA time (67 hours 40 minutes).
