Why does the Minotaur I wear a yellow jacket that "banana-peels" off as it launches? links to the NASA Wallops video NRO L-111 Launch (already cued at the statement in question).

At the end of the video at the video time of 34:04 the announcer says (according to the closed captions; I wasn't able to make out anything clearer by listening):

Mission information including photos will be available on NRO, NASA Wallops and Orthogram websites and their respective Facebook and Twitter accounts.

The next launch from Wallops is an aceteria imrpoved ryan suborbital sounding rocket, carrying the Rock-on educational payload.

Launch is scheduled for 8 AM Thursday, June 24th. Thanks for joining us today.

Question: What is an "Aceteria improved Ryan suborbital sounding rocket"? Exactly what rocket will launch next from Wallops?

Potentially helpful:

    $\begingroup$ I wouldn't expect anything useful from automatically generated captions if I'm not able to make out a clear word by listening - and that's even though I have real issues understanding some washed-out accents... $\endgroup$

    $\begingroup$ I guess the relevant parts are "Terrier" and "improved Orion" (both names of sounding rockets), but there are a few syllables I don't get. $\endgroup$

1 Answer 1


The announcer's diction is quite poor; what's being transcribed as

an aceteria improved ryan suborbital sounding rocket

Is almost certainly

a NASA Terrier-Improved Orion suborbital sounding rocket.

(h/t asdfex)

Terrier-Improved Orion (Wikipedia, Gunter's) is a two-stage, spin-stabilized sounding rocket. "Improved Orion" refers to the upper stage, which has been used as a sounding rocket by itself as well.

Wallops has an article on their website about the June 24 RockOn launch being referred to. (h/t Organic Marble)

The RockOn program is a recurring annual workshop for students to create experiments to fly on sounding rockets; RockOn has used the Terrier-Improved Orion sounding rocket several times before.
