Scientists to grow potatoes on Earth under Mars conditions

Washington:  To save millions of lives on Earth, a team of world-class scientists is ready to grow potatoes in the most inhospitable environments under the tough Martian conditions.

The experiment, led by the International Potato Centre (CIP) in Peru and NASA, is a major step towards building a controlled dome on Mars capable of farming the invaluable crop.

“I am excited to put potatoes on Mars and even more so that we can use a simulated Martian terrain so close to the area where potatoes originated,” said Julio E Valdivia-Silva, research associate of NASA who is leading the project’s science team.

By using soils almost identical to those found on Mars, sourced from the Pampas de La Joya Desert in Peru, the teams will replicate Martian atmospheric conditions in a laboratory and grow potatoes.

The increased levels of carbon dioxide will benefit the crop, whose yield is two to four times that of a regular grain crop under normal Earth conditions.

The Martian atmosphere is near 95 percent carbon dioxide.

“The extraordinary efforts of the team have set the bar for extraterrestrial farming. The idea of growing food for human colonies in space could be a reality very soon,” added Chris McKay, planetary scientist of the NASA Ames research centre.

Beyond the ability to thrive in challenging conditions, potatoes are also highly nutritious.

An excellent source of vitamin C, iron and zinc, they contain critical micro-nutrients missing in vulnerable communities globally.

“How better to learn about climate change than by growing crops on a planet that died two billion years ago?” noted Joel Ranck, CIP head of communications.

“We need people to understand that if we can grow potatoes in extreme conditions like those on Mars, we can save lives on Earth,” he added.

Currently, famine affects 842 million people around the world.

Global warming creates poor soil conditions and increases the number of pests and disease which have the combined effect of limiting harvests globally but particularly in vulnerable areas where poverty, malnutrition and food insecurity already exist.

Understanding atmospheric changes on the surface of Mars will help build more dynamic and accurate simulation centres on the Earth.

The goal is to raise awareness of the incredible illness due to potatoes and fund further research and farming in devastated areas across the globe where malnutrition and poverty are common, the authors concluded. (IANS) (image courtesy:i.imgur.com)

Anticipated Problems That May Effect NASA’s Mars Mission

According to results from the first eight analog space crews, presented at the American Association for the Advancement of Science (AAAS) annual meeting in Washington, D.C., the astronauts are able to successfully complete tasks between 20 and 60 per cent of the time.

Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and tick off problems that may make or break the Mission to Mars.

NASA has formalised plans to send a manned mission to Mars, a journey that could involve 250 million miles of travel on a small spacecraft.

To understand the psychological demands of this Mars journey, Northwestern University has charted a multi-phase study conducted in two analog environments — HERA in the Johnson Space Center in Houston and the SIRIUS Mission in the NEK analog located in the Institute for Bio-Medical Problems (IBMP) in Russia.

The varsity will study the behaviour of analog astronaut crews on mock missions, complete with isolation, sleep deprivation, specially designed tasks and mission control, which mimics real space travel with delayed communication.

“Astronauts are super humans. They are people who are incredibly physically fit and extremely smart,” said Leslie DeChurch, Professor at Northwestern.

“We’re taking an already state-of-the-art crew selection system and making it even better by finding the values, traits and other characteristics that will allow NASA to compose crews that will get along,” DeChurch added.

HERA’s capsule simulator houses astronauts for up to 45 days — a mock mission control outside the capsule — that augments the realism with sound effects, vibrations and communication delays.

Those on the inside undergo sleep deprivation and try to perform tasks. The researchers collect moment-to-moment metrics about individual performance, moods, psychosocial adaptation and more.

The next phase of the research, which began on February 15, involves using the model to predict breakdowns and problems a new HERA crew will experience and making changes to “who works with whom, on what, and when”.

The experiment on the SIRIUS analog in Moscow, will begin on March 15, where four Russians and two Americans, will undertake a 120-day fictional mission around the moon, including a moon landing operation. (IANS)
