The NASA Terrier-Improved Malemute sounding rocket finally took off early Thursday morning. Vapor clouds could be seen from Staten Island, NY to Outer Banks, NC, NASA tweeted.

The rocket was originally set to launch on May 31, clouds, winds, and other factors had prevented the mission from blasting off.

The sounding rocket is scheduled ejected at 4:25 a.m. Thursday, NASA tweeted.

The launch was estimated to last approximately eight minutes. During this time, the rocket shot canisters containing vapors more than 90 miles up in the atmosphere. In doing so, NASA tested the “new multi-canister ejection system for deploying vapors in ionosphere or aurora sounding rocket missions,” according to the Wallops Flight Facility Facebook page.

The canisters then generated blue-green and red artificial clouds that will be visible to spectators watching from North Carolina to New York. This display allowed scientists to observe how particles travel in space.
