A Terrier Improved-Malemute actually. 1. Astronautix, 2. Gunter's Space Page, 3. Wikipedia, 4. NASA pdf. According to Space.com's Watch a NASA Rocket Create Colorful Artificial Clouds Over US East Coast Tonight! that is the type of sounding rocket that will be used. I went to look up the name because it sounds like a mixed canine breed (Malamute's alternate spelling per Merriam-Webster online), and at Astronatix I found there is an amazing variety of sounding rocket names.
Terrier Terrier Oriole: Three stage vehicle consisting of 1 x Terrier + 1 x Terrier + 1 x Oriole
Taurus Nike Tomahawk: Three stage vehicle consisting of 1 x Taurus (Honest John motor) + 1 x Nike + 1 x Tomahawk.
Tater: Three stage vehicle consisting of 1 x Talos + 1 x Terrier + 1 x Recruit
How were names like Terrier, Malemute, Nike, Oriole selected for these apparently nearly interchangeable mix-and-match stages for sounding rockets? More importantly, when assembling a rocket for a given launch, how are the individual stages selected for a given mission? Paging through Astronautix it looks like quite a variety of mixes were named and launched over the last 50 years. Are they just stacked to match the mass and altitude required for the payload, or is there more flexibility available for specific mission needs?

The Terrier-Improved Malemute rocket is scheduled to launch at 9:04 p.m. EDT on June 11, 2017."
