New Ship Terrapin available to buy or to just look at it's concept information.https://robertsspaceindustries.com/comm-link/transmission/15461-The-Terrapin
Also if you own a carrack and want to also get a terrapin consider the gamescom packagehttps://robertsspaceindustries.com/pledge/Packages/UEE-Exploration-Pack-LTI
compared to buying the ships separate this is a pretty good deal. If you already own a carrack you can melt it and use the credits to help buy this package.
They are also selling the Rover but there is no insurance on it afaik so you really shouldnt buy it... plus it's 50 bucks which is ridiculous.
