Research
Each crew establishes different scientific goals they hope to accomplish during their time at MDRS. The majority of the biological studies carried out involve extremophiles, or organisms that are capable of living in extreme environments. Bacteria and algae isolated from the surrounding desert are common subjects of study. These microorganisms have been studied for their DNA, diversity and the environments they live in. For example, in a study for methanogens researchers studied soil and vapour samples from five different desert environments in Utah, Idaho and California in the United States, and in Canada and Chile. Of these, five soil samples and three vapour samples from the vicinity of the MDRS were found to have signs of viable methanogens.
A unique opportunity to combine geology and biology occurs when studying the endoliths found in rocks around the Hab. These species of bacteria are capable of living inside rocks and obtaining the energy they need by photosynthesizing using the light that penetrates the rocks. These extreme organisms are a popular subject of research at MDRS for both geologists and biologists.
Other experiments include a study of the effect of EVAs on the heart rates and blood pressures of crew members, a human factors study that examine the correlation between cognitive ability and mood and a study on how much a space suit inhibits dexterity in comparison to regular street clothes.

Famous quotes containing the word research:
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?””
—Sigmund Freud (1856–1939)
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (1921–1990)
“Men talk, but rarely about anything personal. Recent research on friendship ... has shown that male relationships are based on shared activities: men tend to do things together rather than simply be together.... Female friendships, particularly close friendships, are usually based on self-disclosure, or on talking about intimate aspects of their lives.”
—Bettina Arndt (20th century)
