Crew 205 Crew Journalist Report 18-FEB-2019 Sol 8

Author: Dave Masaitis

Title: A Sol of Great Mystery

Sol 8 began as others have, with crew members emerging from quarters to start a tea kettle and make breakfast. Crew 205 quickly became inquisitive as they peered outside the portholes of our home to see a mysterious white precipitate covering the regolith ridges, with more falling from the sky. While it seemed to resemble snow on Earth, our previous understanding of Mars told us that the planet does not have enough water for such a weather phenomenon to be plausible. It was therefore imperative to treat this precipitate with suspicious caution, especially as it seemed to saturate the regolith and turn it to a rather slippery mud-type substrate. In the interests of crew safety, Commander Grulich reported to Mission Support and announced that our planned EVA would have to wait for another Sol.

Over breakfast, Commander Grulich and Executive Officer Alotaibi consulted with the crew to realign work priorities for a Sol at the Hab. The mysteries of Sol 8 did not stop there. GreenHab Officer Nathan Hadland was analyzing rock and substrate samples in the science dome, when he called on the radio for the crew to come look at something. He had found some samples that, when washed, appeared to be the fossilized shells of some form of invertebrate. Had the crew stumbled on an ancient sea bed while on EVA? By visual appearance, these certainly appeared to be fossilized shells but further testing would be required before any confirmations could be made. Given that some invertebrates on Earth make their shells from calcite, it seemed reasonable that testing a fossilized fragment with a diluted hydrochloric acid solution should create a reaction…and it did! Samples taken from a sampling site within a couple hundred meters of the fossilized shells rendered beautiful crystalline structures, which are suspected to be either halite or gypsum. Both of these pieces of evidence point initially to a region of planetary surface that may have once been an ancient sea bed, so further investigation will be required. While it is far too premature of a discovery to draw any firm conclusions, the mysteries of todays analysis prove even more interesting than the mysterious white precipitate falling from the sky. Are the two perhaps connected?

Some analysis of the fossils may continue into the evening, and the crew will enter its communications window to file their daily reports to Mission Support. Following this, the Commander and Executive Officer will discuss the crew’s priorities of work for Sol 9, before having a dinner of salmon and hushpuppies prepared by one of our more apt cooks, Communications Officer Hannah Blackburn. After dinner, we will likely engage in some table games or perhaps watch Apollo 13, before laying down to get some rest before another Sol.

4) 18:00 PM 20.6° C / 42 %

Changes to crops: Basil plants flowering and the “Mystery Greens” from the seed bank began sprouting. One of the remaining pots of cucumbers was scrapped.

Narrative: The Arabidopsis thaliana experiments are performing very well compared to the previous trial. Two regolith samples appear to be standing out as more viable candidates for plant growth substrates. The pH study on the regolith samples was completed today and the samples’ inability to support Arabidopsismay be in part due to their wettability properties and alkaline nature.

Miracle Grow nutrient supplement was sprayed sparingly on tomatoes, sugar snap peas, and basil. One of the remaining struggling cucumber plants died and the dead biomass weight will be used in our cellulosic ethanol ISRU project. The door remained closed throughout the day due to the consistent snowfall and consequently caused a fairly constant temperature throughout the day. 9.8 g of parsley and 6.4 g of basil were harvested as a garnish for lunch and dinner. Two of the basil plants flowered, which we groomed as a preventative measure against the plant entering another stage in its lifecycle. Upon further investigation, it appears that the radish plant that flowered is healthy contrary to our hypothesis in our last report.

Harvest: 9.8 g parsley

6.4 g of basil

Support/supplies needed: Several pots and the large grow bed appear to be over-saturated. Should we decrease the frequency of watering from 4 times a day to allow the soil to aerate.

Astronomy Report – February 18th

Crew Astronomer:Natalia Larrea

MDRS ROBOTIC OBSERVATORY

Robotic Telescope Requested: MDRS-WF

Objects Viewed:

No observations for MDRS Target 1 were captured using MDRS-14 last night due to cloudy weather. We are still waiting for the sky to clear to obtain further measurements.

This morning we submitted an additional observation request for Orion Nebula using MDRS-WF telescope. Observations were set at 3 sec exposure using RGB and Lum filters. Right Ascension correction for this object was set at -10 arcmin.

Problems Encountered: Bad weather conditions.

Sol Summary 8 – February 18th

CREW 205 Sol Summary

Sol: 8

Sol Summary title: Fossils, mystery and other things

Author: Maria Grulich

Mission status: Nominal

Sol activity summary: The EVA suits have been fixed last night successfully.

This morning the crew woke up with the smell of pancakes with blueberry and apple toppings prepared by commander Maria with a banana milkshake to top it off.

The planned EVA had a chance of 30% snow but when we looked outside the window, we just could see white everywhere. Therefore, the decision was made to cancel the EVA.

It gave us the chance to catch up with science and maintenance of the habitat. The crew astronomer for the day is Natalia and she submitted a new request with the help of Ghanim who is today’s XO, for the Orion nebula as yesterday no new observation could be made.

Veronica and Dave exchanged the water filter. The tunnels were brushed to clean them from snow. Nathan continued the characterization of the samples. He made some interesting observation as some of the samples that were taken yesterday turned out to be fossilized shells which is very exciting as this means it is a sign of a former sea at the Moon area. In the afternoon he took care of the ISRU plants in the Greenhab which luckily survived the night.

Dave prepared some noodle soup and tonight we are getting salmon and hushpuppies and rice by comms officer Hannah.

Besides that, the crew edited some of the videos and took some extra images for the outreach project.

The crew journalist of today took some nice pictures of the hab in snow and the fossil shells.

After dinner, we’re hopefully going to play some games or watch a movie as a team.

Look ahead plan: The crew intends to conduct the EVA planned for today again, for tomorrow if the weather outside allows it. In addition, the science continues with characterization and observation of the Arabidopsisseedlings and their development in the regolith substrate and the editing of the videos will continue.

Anomalies: EVA cancelled

Weather: snow all day
