Crew 198 Operations Report 12-Nov-2018

SOL: 2

Name of person filing report: Dana Levin

Non-nominal systems: Generator, Report filing, Rover Sojourner, engineering airlock electrical sockets, engineering airlock light, lower deck hab wall heater,

Notes on non-nominal systems:

– Generator: Last night the generator had an underspeed cutout failure. While our crew has not been trained on generator mantinance and repair we were able to obtain assistance from our local benevolent Martian overlord Shannon.

– Event log;

o Around 1930 generator started with SOC at 46%

o 2000 generator cutout, temperature reading at 212F reporting a generator underspeed alert, generator restarted

o 2100 generator failed again, restarted Shannon alerted

o 2140 generator failed again and inverters cutout killing power to the entire MDRS complex. We drained coolant from the overflow tank including removing some congealed substance off the top of the tank, generator left off overnight

o At 0645 SOC was 26% solar began charging batteries

o 0800 generator started after evaluation by DG at 1800 RPM, continued operation for 1 hour and was shut off

o TODAY: 1720 SOC at 84% generator started as sunset. 1745 generator cutoff again.

– Current theory; mechanical obstruction to generator prevents full RPM which means current ops normal habitat power load exceeds generation capacity and generator stalls out

– Report filing: we have had continued trouble with non updated report templates requiring a back and forth between MDRS and mission support demanding reports filed in different formats. This yielded significant crew frustration

o Proposed solution: reports could be turned into google forms. The links to these forms sent to the station crew to standardize filing format. This would also allow centralized data collection and presentation including some values that could be graphed over time and organized for presentation/analysis easily.

o We attempted to formulate such forms but our internet connection did not allow connection to the google servers

– Sojourner: Shannon had used Sojourner two days ago but the battery drained to the point where she was unable to safely return to the habitat. Rover was left about 4 miles north of the Hab beside brae highway.

o Our schedule was rearranged to enable 2 of our instructors to leave the hab to recover the rover in the Hab car while our students were undergoing lectures by a third instructor. This was completed without incident and luckily our pre-planned schedule was sufficient to absorb this unexpected non crew/non sim related contingency.

– Engineering air lock light and power sockets are still inoperable.

– Demos Rover remains with battery drained and empty of water, rover is inoperable.

– 350 ATV is inoperable, likely with a dead battery that has yet to be replaced

General notes and comments:

Please standardize reports and consider loading them into google forms or some kind of email template with a hab specific email. This saves data by preventing redownloading of mail to different accounts, avoids incorrect forms transmitted to crew or filed by crew, and makes data transfer easier

Summary of internet: functional

Summary of suits and radios: using our own

Summary of Hab operations: nominal despite facility difficulties

Summary of GreenHab operations: none

Summary of ScienceDome operations: none

Summary of RAMM operations: none

Summary of any observatory issues: none identified as we are not using observatory

Summary of health and safety issues: none
