EVA # 15
Author: Clare Fletcher
Purpose of EVA: Attempt to find a photograph a site previously known as “White Mushroom Field” by Henrik Hargitai to note charge over time in the environment. Gain field spectral measurements of the mushrooms.
Start time: 1000
End time: 1200
Narrative: The site of these yardangs or “mushrooms” was very easy to find. There was a nice flat plain to drive the robot across and continue testing its mobility across the plain and some of the slopes. The site described as “White Mushroom Field” by Hargitai was also easy to find, and looked to be in reasonable condition compared to the 2006 photo taken by Jon Clarke. The "mushrooms" turned out not to be anhydrite, but just a white/grey mudstone. They also had concretions in them which was interesting. We attained a spectral signature for the "mushrooms" as well as other features in the landscape.
Destination: Field of yardangs near to Pooh’s Corner (to the West). Parking rovers at 518716, 4251064. Walking to 518598, 4251110. Co-ordinates to the site provided by Henrik Hargitai in a previous paper.
Coordinates (use UTM WGS 84): Parking rovers at 518716, 4251064. Walking to 518598, 4251110.
Participants: Steve Hobbs, Clare Fletcher, Alex Tobal
Road(s) and routes per MDRS Map: Exit Hab via main airlock. Drive down driveway to Cow Dung Rd 0110. Drive North on Cow Dung Rd 0110 until straight between Marble Ritual and Pooh’s Corner. Walking within 200m of rovers.
Mode of travel: Driving and walking.

MUSK OBSERVATORY (MO)
Solar Features Observed: Sun spots observed, imaged, and fully processed for emailing (attached).
Problems Encountered:
08:25
Sun was not fully on ’scope until 09:00 so time in MO will typically be 08:30 to 14:30,
because of the state of the shutters, the ’scope and dome floor are at high risk of being water damaged from rain ingress,
on the floor near the western alcove the cabling coming out of the floor is a tripping hazard and some of the cables are damaged or at risk of being damaged (image attached),
on power-up the Celestron Hand Control wanted ENTER to wake from HIBERNATION then asked for TIME and DATE then showed CGO PRO READY,
it did not show ALIGN SUCCESS so I pressed SOLAR SYSTEM,
SOLAR SYSTEM showed MOON with a “W” in top right corner, and I could not access MENU to get to SUN,
pressing MENU changed the ”W” to an “E” and I was able to scroll to SUN which slewed ‘scope to the Sun,
10:30
‘scope struggled to get crisp images all day, with no prominances but several groups of fuzzy Sun spots observed,
the observed Sun spots were the same ones seen for the last few days.
SharpCap
as usual the program is very washed out to look at and attempts to give it better contrast by adjusting Windows 10 display settings were unsuccessful,
in the Quick Guide (MOQG), I suggest software be named consistently, i.e. SharpCap (not Sharp Cap),
as yesterday, instead of saving to the Capture folder as an .avi file, SharpCap saved 1,000 JPG images so I changed the Output Format to .avi.
in MOQG at Step 14. p25, I suggest this be checked in top, right corner of window.
AutoStakkert
in MOQG chapter on p28, I suggest say in Step 1. that program opens in two windows, the sizes of which can’t be changed (?),
in MOQG, I suggest software be named consistently, i.e. AutoStakkert (not Autostakkert),
in MOQG, I suggest Step 6. to read “After first two steps of STATUS in middle panel of left window show green ticks…”,
12:15
Registax
in MOQG, I suggest Step 2. to read “…the stacked tiff file from AutoStakkert…”,
in MOQG, I suggest Step 3. to read “The file will automatically open in the Wavelet tab (top, left)…”.
Photoshop
in MOQG, I suggest software be named consistently, i.e. Photoshop,
in MOQG, I suggest Step 1. to read “…Open Photoshop in the task bar and in the Window dropdown menu ensure Tools is selected and use the Quick Selection Tool in the Tools Panel.”,
in MOQG, I suggest Step 2. to read “…Chromosphere and Prominence PNG files in the SharpCap Capture folder and open them. If you didn’t image any Prominences then just open the Chromosphere file and process that.”.
14:00
outcome for the day is 1,000 frames from SharpCap processed through AutoStakkert, Registrax, and Photoshop, then prepared for this Astronomy Report to Mission Support (image attached).
15:00
successfully parked ‘scope in HOME POSITION, HIBERNATED, and completed Closing Procedure per MOQG chapter,
returned items to storage locations and locked up MO.

Sol Summary – January 26th
Sol: 5
Summary Title: Data acquisition
Author’s name: Andrew Wheeler
Mission Status: Nominal
Sol Activity Summary: Sol 5 dawned bright clear and cold, perfect weather for EVAs. It was also Australia Day back on Earth and an opportunity for some Aussie delights. For us it was vegemite on toast with a tropical fruit platter as that was all we had. (The toast was actually bread and the fruit platter was dehydrated bananas, mango, apple and blueberries and the blueberries were actually in pancakes). Morning tea saw the unveiling of the TimTams® and, for afternoon tea, lamingtons. The hab received some tender loving care on both levels with sweeping up and vacuuming away the evidence of our external activities. The EVA for the day saw a return, along Cow Dung Road past Cowboy Corner, to the location of the spectral recordings of the previous day to collect further data and test the robot rover’s mobility on additional different slopes and surfaces. The evening meal was burgers and lamingtons. A productive day by all.
Look Ahead Plan: Weather dependent as always, tomorrow will see an EVA return to the Kissing Camel Ridge for investigation of the geological boundary between that and the Hab Ridge. This will be followed by an EVA to the Galileo Road in search of access into the Candor Chasma for geological samples and spectral targets.
Anomalies in work: Nothing to report.
Weather: Clear crisp morning at 0 Celcius rising to low teens during the day. Some minor clouds forming over the mountains during the day. No precipitation. Humidity dropping from near 80% to below 50%. The wind strengthened from gentle during the day.
Crew Physical Status: nominal
EVA: EVA 9 with Steve, Clare, and Rob to the Tharsis Montes area north of Cowboy Corner for robot rover testing.
Reports to be filed: Sol Summary, Journalist Report, Greenhab Report, Operations Report, EVA report, EVA Request(s). No Astronomer report as yet.
Support Requested: Nothing to request.

Journalist Report – January 26th
Australia Day
Sol 5 began with another interesting convo over breakfast – this time about human lung capacity and blood oxygen saturation, and whether/how a human could feasibly survive atmospheric depressurisation on Mars – at least, long enough to reach and operate an airlock. Somehow this led into a genealogy discussion about family trees, our ancestors, and their connections to Australia. Very fitting, given that today was Australia Day.
For international readers: Australia Day is the country’s official national holiday, observed by all its states and territories, and is one of the biggest events in the Australian calendar. The date of 26 January marks the anniversary of the British First Fleet’s landing near modern-day Sydney in 1788. While this specific date means different things to different Australians and has become somewhat controversial, for most it means a day off to come together and celebrate in solidarity. It’s also a day around which many citizenship and award ceremonies take place.
To commemorate the occasion, today was light-on with EVAs. We only conducted one, to Cowboy Corner again – but it was a doozy, pitting humans against Steve’s rover to compare their spectral capture and traversal capabilities. Humans won (the battle at least, maybe not the war). The team also took the opportunity for a flag-planting ceremony with the crew’s mascots.
Meanwhile, back at the hab, Commandrew was busy making improvised ‘lamingtons’ while dressed in his patriotic red, green and blue (see Pascal Lee’s Flag of Mars). Somehow they turned out great. We also baked more bread – at one point having three different loaves on the go – and improvised some ‘pseudo-snaggas’ that turned out… not-so-great.
Highlights of the day: None of the crew have known convict ancestors, Clare’s Scottish (Murray) side once owned a castle (Blair Atholl) with its own private army, Andrew’s eligibility to wear four different tartans, Rob’s Boer War family heirloom.
Lowlights of the day: Clare’s other side is a family of doppelgangers and she literally has no imagination (that’s not a joke), bread addiction, what happens on EVA stays on EVA.

MUSK OBSERVATORY (MO)
Solar Features Observed: Sun spots (imaged) and solar prominences
Images submitted with this report: several images related to maintenance/repair, and an unprocessed one of the first 1,000 captures of Sun spots.
Problems Encountered:
10:25
entered observatory and removed cover from scope,
photographed position of scope with N, S, E in shot,
set up laptop and personal belongings, and decluttered work space (see pics),
a broken-off small, white, plastic positioning tab from the drawers was found in the lowest drawer and left there, (see pic)
dome was successfully rolled around to approximate position for use,
both shutters were opened without any glitches but, contrary to Peter’s direction to not use the lower shutter, it was required to be fully open in order to see the Sun which was low in the sky,
took more photos of pre-power scope use,
Musk Observatory Quick Guide (MOQG) cover title and elsewhere uses font/word art that is difficult to read,
MOQG instructions on p10 point to eyepiece attachment steps on p18 but they’re on p19 in chapter Visual Observing,
MOQG instructions on p10 point to camera attachment steps on p19 but they’re on p21 in chapter Solar Imaging Setup,
MOQG chapter Processing the Image on p27 is not listed in Table of Contents (ToC),
MOQG ToC chapter name for end of mission closing procedure doesn’t quite match chapter title,
MOQG chapters on Alignment Problems, Tuners, Focus Problems are not listed in ToC,
MOQG ToC chapter titles for Image Processing – Autostakkert, Registax and Photoshop don’t match chapter title,
12:35
switched on scope at pier, removed lens cap, then followed these instructions (deviation from instructions are in bold):
Once it’s at the index position it should go to the date and time routine,
I pressed ENTER and scope went to SWITCH POSITION then asked for time.
time and date (Standard and Mountain Time) were successfully entered,
If ALIGN SUCCESS doesn’t appear, and it asks for a 2-star alignment, then scroll (#6 and #9) to LAST ALIGNMENT and click ENTER,
I scrolled to LAST ALIGNMENT, clicked ENTER
Once you have ALIGN SUCCESS and its READY Click MENU,
I got ALIGN SUCCESS and CGE PRO READY then clicked MENU,
Scroll to UTILITIES and then HOME POSITION,
I scrolled to UTILITIES and got HOME POSITION and pressed ENTER,
In the HOME POSITION menu scroll until you get to SET HOME POSITION. Click ENTER,
there is no SET HOME POSITION in the HOME POSITION menu. There is only GOTO and SET,
I scrolled to SET and pressed ENTER,
the screen blinked while reading SETTING HOME POSITION then returned to SET in HOME POSITION,
Then scroll to HIBERNATE and shut down. It should operate normally then, but follow the shutdown procedure on page 15,
there is no GOTO HOME POSITION in the HOME POSITION menu but there is GOTO, so I clicked GOTO,
the scope slewed back and forth a bit and screen read GOTO in HOME POSITION menu,
there is no HIBERNATE in the HOME POSITION menu,
HIBERNATE is in the UTILITIES menu so I went there and completed the close-down procedure per MOQG p15,
15:35
scope was facing north and on top of the mount when I switched it off at the pier.
at approx. 14:45 it was very noticeable that the Sun was becoming fuzzy q.v. low in the sky and light travelling through much more atmosphere,
on speeds #4 and #3 (possibly others) the hand controller Direction Keys, if held down for a second or so, caused the motor to jump to high speed,
the lack of tightening screws in the eyepiece tube is workable but not ideal,
the USB cable to the laptop disconnected easily but was pushed back in securely and camera re-initiated in SharpCap,
prominences and Sun spots were seen and 1,000 images taken of the latter,
an unsuccessful attempt was made to capture a flat exposure,
16:00
closed observatory and returned to HAB.

Summary Title: A day of rest
Author’s name: Andrew Wheeler
Mission Status: Nominal
Sol Activity Summary: Today was scheduled to be a day of rest and personal time. However, it didn’t quite turn out that way. One crew member awoke to a severe migraine and another to a stomach upset and their wellbeing was our main concern. Nevertheless, washing and cleaning was able to be done and a very short EVA to return the solar logger it’s recording point was carried out in the early morning. The Mars jigsaw puzzle was completed and signed and an issue with the lower level gas heater was remedied.
Look Ahead Plan: We will return to robot rover testing on the ground around the hab in the morning and an EVA to the stream draining from Tharsis Montes in search of concretions in the afternoon. If the weather holds, the solar observatory will also be operated.
Anomalies in work: Lower level gas heater anomaly – see operations report.
Weather: Clear crisp morning at -5 Celsius rising to low teens during the day. High cirrus cloud later in the day. No precipitation. Humidity continuously dropping from near 60% to below 40%. The wind was faint to gentle during the day.
Crew Physical Status: Severe migraine headache as well as stomach upset – see HSO report.
EVA: EVA 12 with Andrew and Clare to return the solar logger to it’s recording position and an external inspection of the hab tunnels.
Reports to be filed: Sol Summary, Commander’s Report, Greenhab Report, Operations Report (including an HSO report), EVA report, EVA Request(s). There is no Astronomer report for today.
Support Requested: Nothing to request.

Non-nominal systems: Hab downstairs wall heater
Notes on non-nominal systems:
At around 18:30pm, the crew upstairs heard a strange sound coming from downstairs (sounded like rushing water). We went downstairs to investigate and smelled gas. We saw that the wall-mounted heater (to the right of the engineering airlock) that the left side of the heating grill was operating normally (glowing red), but the right was not glowing and there was a visible flame behind. Commander Andrew immediately turned the thermostat to the off position as I radioed mission support to advise on the situation. The flame then went out and the rushing sound stopped. We opened the engineering airlock door to vent the gas from the room. No alarms were triggered. The gas heater thermostat is now set to “off” and confirm the pilot light is still burning.
