Past Launches 1969-present

General Information

Launch Timing

Most launches have a launch window which may be days or weeks long. The launch(es) may take place at any time during the window, depending on logistical, geophysical, weather, and other considerations. It is rarely possible to predict the exact time at which a given rocket will be launched. Launches are usually at night for auroral studies, but some daytime launches are performed for other types of research.

Mission Numbering

Feb. 18-April 7, 2003	1	N	Terrier-Orion 41.034 UE	NASA	Conde/ Univ. of Alaska	Plasma Physics	1N, 1S, 2,3,	2	NO		12:50 AM, March 25, 2003

In the vehicle column of the table above, an alpha-numeric mission code follows the rocket motor(s) designation, eg. "Terrier-Orion 41.034 UE". The first number in the code identifies the the rocket motor(s). In the case of our example above, 41 corresponds to Terrier-Orion. The following table will help you decode motor designations. Hyphenated motor names designates multi-stage rockets with two or more different rocket motors.

The second number of our example, i.e. 034 is a sequential flight identification number assignment for the year. The letters UE in our example, identify the agency and discipline responsible for the flight -- a University (University of Alaska, Fairbanks) conducting research in Plasma Physics. The following table will allow you to decode the two letter identifier.

Agency:

A - Government agency other than N or D (below)
C - Industrial corporation
D - Department of Defense
G - Goddard Space Flight Center
I - International
N - NASA Center other than G or W
U - College or university
W - Wallops Flight Facility

Discipline:

E - Plasma Physics
G - Galactic Astronomy
H - High-energy Astrophysics
L - Planetary Atmospheres
P - Special Projects
S - Solar Physics
T - Test and Support
U - Upper Atmosphere Research

As one would expect, the size of the rocket motor limits the weight and size of the instrument payload sent aloft, the rocket's altitude at apogee, or the duration of flight through a particular region of the thermosphere. Another weight consideration is a parachute recovery system. So as with all things, there is a cost-benefit calculation involved when planning a mission. You wouldn't want to use an Aries motor when an Orion(Hawk) will do the job. The following table gives parameters of typical sounding rocket motors.
