The Challenges Of Living In Space - Sentinel Mission (2024)

FAQs

What are the challenges of space mission? ›

Exploration missions that leave the Earth's protective sphere, however, will have to overcome many challenges, from conditions in space such as cosmic radiation and hazardous environments to human-specific conditions such as space adaptation syndrome (motion sickness), spatial memory, visual motor performance, bone ...

To bring such a mission to the Red Planet from fiction to fact, NASA's Human Research Program has pinpointed five hazards that astronauts will encounter on their journeys. These include space radiation, isolation and confinement, distance from Earth, gravity (and the lack of it), and closed or hostile environments.

Our bodies rely on gravity to tell which way to build our bones. In space, with no gravity to supply this direction, these bone growth systems break down. Also, astronauts typically don't use certain muscle groups to support their bodies in microgravity. This causes a large amount of muscle to be lost in a short time.

We would also need to create systems for maintaining a breathable atmosphere, protecting ourselves from radiation, and mitigating the effects of low gravity. Another challenge of space colonization is the potential environmental impact of human activities.

The problem of space junk

Humans have left a lot of junk on the Moon, including spacecraft remains like rocket boosters from over 50 crashed landings, nearly 100 bags of human waste and miscellaneous objects like a feather, golf balls and boots. It adds up to around 200 tons of our trash.

Answer. Astronauts on Mars will need a renewable supply of oxygen, water, power, and food in addition to a place to live in order to survive in the harsh Martian environment.

Zero gravity and a sunrise every 90 minutes can disrupt an astronaut's health, both physically and mentally. The crew must combat motion sickness, claustrophobia and homesickness every day. They also must be prepared for any medical emergencies that may arise.

Star Wars would have you believe that the greatest challenges to space travel is asteroids, lack of resources like water or fuel, or even the threat of unfriendly, intelligent alien life. But in reality, scientists are finding that the biggest obstacle to today's space travel is dust. Yes, space dust.

Life in space

Space is very dangerous – and without protection, people would not be able to survive there. In space, there's no air – so you couldn't breathe. It's cold – so you'd freeze. And there's lots of nasty radiation (from the Sun, and from the rest of the Universe), so you'd get really, really bad sunburn.

In space, astronauts may face decreases in blood volume, orthostatic tolerance, and aerobic capacity while also experiencing increased arrhythmias. Although the cardiovascular system functions well in space, the body does not require as much work from the heart (still a muscle, after all) in microgravity.

What is it like living in a space station? ›

Microgravity means that crew members have many obstacles to their regular routines, such as eating, sleeping and hanging out. The space station has no refrigeration, meaning all food has to be stored carefully and is often vacuum-packed.

A normal week in space is designed to mimic the astronauts' routine on Earth as much as possible, and consists of five days of work and two days of rest (although Saturday is also used for chores). During their time off, they often relax by watching Earth go by. Some read books, play an instrument or listen to music.

While Mars' day and general composition are similar to Earth, the planet is hostile to life. Mars has an unbreathable atmosphere, thin enough that its temperature on average fluctuates between −70 and 0 °C (−94 and 32 °F), yet thick enough to cause planet-wide dust storms.

Space colonization (also called space settlement or extraterrestrial colonization) is the use of outer space or celestial bodies other than Earth for permanent habitation or as extraterrestrial territory.

Habitat Design and Construction. Designing and building habitats that can sustain human life on Mars is another crucial part of colonizing the planet. The habitats must provide protection from the planet's harsh environment, including extreme temperatures, radiation, and dust storms.

The main challenge is the huge distances between objects in space. The scale and size of the distances between stars can be difficult to comprehend. Travel to a nearby planet such as Mars would take a couple of years and even then only when the planets' orbits are in alignment.

Space Shuttle Challenger breaks up during its 1986 launch resulting in the death of all seven crew members. As of 2024, there have been 19 astronaut fatalities during spaceflight that either crossed, or was intended to cross, the boundary of space as defined by the United States (50 miles above sea level).

1. Radiation. The first hazard of a human mission to Mars is also the most difficult to visualize because, well, space radiation is invisible to the human eye. Radiation is not only stealthy, but considered one of the most menacing of the five hazards.

A commercial spacecraft that was making a bid to become the first US Moon lander in more than 50 years ran into trouble hours after its 8 January launch. The probe, known as Peregrine, made it off Earth and into deep space — but soon began to leak propellant and tumble out of control.
