Wallops employee Jeff Cain sets a fin on a Terrier sounding rocket motor at the Poker Flat Research Range in Alaska in preparation for a campaign with five launches in January and February 2017 carrying payloads to study auroras. While the crew is in Alaska preparing the rocket motors (they will be back home for the holidays), the finishing touches are being made on the payloads back at Wallops to prepare them for shipment up north.
