EDLS Experiment on Mir

Characteristic Motion

EDLS ASTRONAUT CHARACTERISTIC MOTIONS
No.	Characteristic Motion	Description	Sensor*
1	Landing	Crew flying across module and landing on (utilizing) sensor	HH, FR, TP
2	Push-Off	Crew pushing off and flying	HH, FR, TP
3	Flexion/Extension	While using sensor, flexing or extending limb	HH, FR
4	Single Support	Using only one limb for support	HH, FR
5	Double Support	Using two limbs for support	HH, FR
6	Twisting	Twisting body motion i.e., shear forces expected	HH, FR
7	Orienting	Re-orienting oneself usually during posture control	HH, FR, TP
8	Fly-by	Crew guiding their flight across a module	HH
* Key: HH = Hand Hold, FR = Foot Restraint, TP = Touch Pad

Raw Force- and Moment Data

You can download some of data files by clicking once at the corresponding file name. The file names are coded in Mission Elapsed Times. The files are binary data files created by Matlab. If you wish to plot the data, start Matlab, and at the command prompt type: plot(Fx) . This will plot Fx. You do the same for Fx, Fy, Fz, Mx, My and Mz. Also, the variable description in the matlab file has a short description of the crew motion that was registered on the particular sensor. The "f","h" and "p" characters in the filename stand for the corresponding sensor (i.e, h=hand-hold, p=touch-pad, f=foot-restraint).

Summary Results

Given below are a few sample files from NASA-2 mission.The complete data is now distributed via CD-ROMs.

MISSION	DAY	TIME	FILENAME	SIZE (KB)
NASA-2	MD 185	16.6400 sec.	185132410_p01.mat	128
NASA-2	MD 185	13.5680 sec.	185134154_f01.mat	160

Extensive spreadsheets are available with the data collected from missions NASA-2 and NASA-4. These spreadsheets proivide maximum forces, moments, RMS values, etc. A sample database (in ASCII format) can be downloaded below.
