EVA #: GenEVA_1 (codename Christmas EVA)

EVA Date: 12-24-13

EVA time slot: morning/noon (10am-1pm)

Objectives and Plan overview, please comment on preEVA expectations:

1) Space Suit Mobility

2) Check Coms Systems

3) Test entire EVA procedure (prep, planning, checklists, day before, day of, waypoints, post)

Narrative EVA report

1) Heavy backpack, adjusted. Fog+helmet+foothills = dangerous. Kneeling and bending down was fine. Despite cold temperatures (~35degF), away team members all reported being hot. Suggest limiting layers to long-underwear tops and bottoms but no fleeces underneath EVA jumpsuits when on walking EVA.

2) Radio's has severe issues. Several turned off or stopped worked. Only used Nick's radio. It would turn off and cycle power.

3) EVA procedure over all satisfactory.

-Team's neck really hurts, head against helmet, one crew member's shoulders are pretty red

-tired, from heat

-helmet pushed head forward bent back

-massages are great

-once people were outside radios were easier to understand

-good idea to do coms check before they head out

-radioed in at 12:00 for 2nd quarter check and there was no response

-attempted to establish contact over several mins. but no response

-heard voices at 12:12

-re-established coms at 12:18

Hot, Foggy and troublesome radios

Within 5 mins

Charles's: microphone didn't work

Ian's: radio cut off and didn't work rest of trip

Nick's would turn off and and when turned on

did not work on far side of Mt.

Severe fogging, spitting water onto helmet worked, vision is a small window

Glad to have water, drank a bit to a lot

First half a climb second half flatter

Helmet forces head forward

Adjust straps on SCLSS

Walked in shade bc hot

Yell pretty loud to get attention, 10 yards

SCLSS: Pack's ran the entire EVA, but were awkward

Helmet, visibility: Severe fogging, condensation

HM's came unseated from collar, air hose pushed it out (X).

Air flow: felt very weak, didn't seem to help at all

Coms, usage, drop outs: most raidos failed, one worked but turned off and had to be turned back on

Gear, boots, gators, caps, gloves:

Ian's glove combo was good for camera use

Water, usage, accessibility:

GPS: no issues

Digging Equipment: Fogginess hard to see what you're hitting. Affects accuracy and hard to ID.

Other: GoPro's died quickly

Waypoint Check in:

>worked

Half Hour Check in:

>worked

Airlock Procedures:

>3 mins was good sim.

>Request clearance to enter hab

Invigorating experience to finally be outside on Mars with the suits on.
