Nutrition Prevent Astronauts From Malnourished During Space Missions

For thousands of years, nutrition has been a driving factor behind the success or failure of human exploration. This is particularly true in the case of space flight. It is vital to prevent the astronauts from becoming malnourished during missions, which often last months.

But modern space nutrition goes further than that. It aims to maximize the crew's performance while reducing the damaging effects of space flight and protecting against long-term health risks like cancer and heart disease.

Space Travel May Lead To Cardiac Repair In Astronauts

Astronauts live in a practically weightless environment, scientifically known as microgravity. The effects of microgravity on the human body are various and fascinating some of them damaging, some redeeming.

New research finds a therapeutic purpose for the impact of microgravity on human stem cells. The study was published in the journal  Stem Cells and Development. From the brain shifting upward to muscles shrinking, veins swelling, and astronauts' faces getting puffy, the effects of microgravity on the human body are fascinating.

Genetic Code Is Dormant In Astronauts During Hibernation

Bears do it. So do groundhogs, squirrels, turtles, and many other animals. Humans, however, can’t hibernate at least not right now. But scientists exploring the genetic underpinnings of hibernation in animals think they may be able to unlock the same biological superpower in humans.

That feat could transform medical care during both routine surgeries and dire medical emergencies when patients cannot immediately get access to lifesaving treatment. It could also make it possible for astronauts to snooze their way on long missions to Mars and other destinations in deep space.

Deep Space Travel Cause Cancer in Astronauts

When Elon Musk unveiled SpaceX's plans for sending humans to Mars in September 2016, he had a remarkably cavalier attitude towards the dangers of space radiation. There's going to be some risk of radiation, but it's not deadly," he told the audience in Guadalajara, Mexico back then.

There will be some increased risk of cancer, but I think it's relatively minor. The radiation thing is often brought up, but I think it's not too big of a deal. The study was published in the journal Proceedings of the National Academy of Sciences.

Astronauts Face Space Sick In Space Travel

Astronauts get space sick in the space travel from Earth to the International Space Station. Yes, astronauts can get space sick traveling to the International Space Station. It is less likely traveling in the cramped Russian Soyuz spacecraft used to transport astronauts there now than the old Space Shuttle that was used until 2011. The ability to move around in the Space Shuttle increased the chance of space sickness happening. Space sickness affects up to half of the astronauts during their first few days on the space station.

Effect Of Microgravity On Sperm

NASA is sending sperm cells into space in the hopes to investigate whether a conception of a human life is possible in a zero-gravity environment. The American space agency is moving one step forward in space exploration as the Micro-11 mission carries frozen human and bull sperms aboard the SpaceX Falcon 9.

In a statement, NASA said the scientists are studying the effects of weightlessness on the sperms' ability to fertilize the egg, which is a crucial stage in conception. Previous experiments with sea urchin and bull sperm suggest that activating movement happens more quickly in microgravity, while the steps leading up to fusion happen more slowly, or not at all. Delays or problems at this stage could prevent fertilization from happening in space.

Astronauts Use Technology To Survive In Space

Researchers have proposed an upper limit on exoplanet gravity that would allow a trained athlete to live comfortably on a distant world. Astrobiologists often consider the potential habitability of newly-discovered exoplanets by measuring the properties of their atmospheres.  However, as the Apollo Moon missions proved, humans can use technology to survive in a distant, hostile atmosphere.

Keeping Kidney Stones At Bay During Spaceflights

A new, painless, non-invasive procedure that harnesses ultrasound technology to reposition kidney stones, in an effort to offer the sufferer quick relief, will undergo testing in emergency patients. The development and assessment of the new technology are led by University of Washington and UW Medicine, in collaboration with other universities and agencies.

Kidney Stones

Kidney stones are an increasingly common condition that affects 1 in 11 Americans during their lifetime. The condition is even more frequently encountered in astronauts during space missions. The hope is that the new technology could benefit astronauts as well as Earth-side patients.

Deep Sea RV: New Habitat for Astronauts

Space RVs might sound like something the Jetsons would take on a cosmic road trip, but Lockheed Martin is going to make it a reality for astronauts venturing to Mars and beyond.

NASA gave the aerospace titan, along with Boeing, OrbitalATK, Bigelow Aerospace, Nanoracks, and Sierra Nevada Corp.’s Space Systems, a combined $65 million to prototype a deep-space habitat for its NextSTEP (Next Space Technologies for Exploration Partnerships) program by the end of the year.

Space Changes The Body In Several Ways

Scientists conducted a study at unraveling how nature versus nurture plays out in space. As part of NASA’s Twins Study, they collected biological samples from each of the Kellys before sending Scott to the International Space Station for a year starting in March 2016.

Meanwhile, his brother Mark, who retired as an astronaut in 2011, remained on Earth to serve as the control subject. By analyzing how each twins’ biological markers evolved during the mission, the researchers learned a great deal about how the human body reacts both physically and mentally to extended periods of spaceflight.

Astronauts Trying To Find Better Cancer Treatments In Space

With careful attention from an astronaut, a blood cell experiment may deliver improvements on cancer-fighting treatments. There's a lot of blood in space right now to be exact, there are a lot of endothelial cells that come from blood vessels.

Astronauts are helping study these cells aboard the International Space Station (ISS) as part of the Angiex Cancer Therapy trials, which NASA astronaut Serena Auñón-Chancellor introduced in a new video. The study was published in NASA.

Astronaut Gets Sick In Space

Astronauts are among the fittest and healthiest people in the world. They are rigorously trained, vetted, and quarantined before they’re allowed up in space and yet, despite all those precautions, they do sometimes get sick.

And because space missions are on a strict schedule planned far in advance, sick astronauts on a space mission can't just pop down to Earth to see a doctor. But when astronauts fall ill, they don't have to worry NASA and other space agencies that have missions aboard the ISS are prepared.
