Nine Months in Space Can Permanently Alter The Body, Leaving Astronauts Sunita Williams and Barry Wilmore with Possible Long-Term Health Effects.

It was a mission that lasted Far Longer Than Planned.

United States Astronauts Sunita “Suni” Williams and Barry “Butch” Wilmore Went To Space On Board The Boeing Starliner Calypso On June 5, 2024. They were Meant To Spend Eight Day Days On The International Space Station (ISS).

But as The Spacecraft Was Approaching the Station, ITS Thrusters Malfuntinated, and Nasa Ordered The Astronauts To Remain On The Iss While Figuring Out How to Bring Them Back.

That Lasted Nine Months, or 288 DaysMaking Williams and Wilmore Two of the Longest-Serving Nasa Astronauts in Space On A Single Mission.

WHHO HAS SPENT THE LARGE TIME IN SPACE?

The ISS ORBITS AT AN ALTIVITY OF 354KM (220 thousand), While The Average Distence to Mars from Earth is a Staggering 225 Million Kilometres (140 million thousands).

Astronaut Frank Rubio Holds The Record for Nasa’s Longest Space Mission, Spending More than A Year on The ISS.

The Overall Record for Single Spaceflight Belongs to Russian Valeri Polyakov, Who Spent 437 Days On Board The Mir Space Station.

WHEN DID THE SPACEX CREW-9 MISSION RETURN TO EARTH?

The Spacex Dragon Spacecraft that Carried Williams and Wilmore to Earth Splashed Down at About 5.57pm Time Time (21:57 GMT) OFF THE COAST OF FLORIDA, AFTER UNDOCKING FROM THE ISS AT 05:05 GMT.

On Board with Wilmore and Williams was Russia’s Roscosmos Astronaut Aleksandr Gorbunov.

NASA PROVIDED Live Coverage of the lead-up to the splashdown.

Now Back On Land, The Crew Will Have to Adjust To Being Back On Earth, Both Physically and Mentally.

How Does Living in Space Harm The Body?

Spending months in microgravity is brutal on the body. Without The Earth’s Gravitational Pull, Muscles Shrink, Weaken Bones and Bodily Fluids Shift.

Astronauts Lose Muscle Mass Rapidly Because they do not use their legs to support their weight. Their Bones Become Fragile and They Lose 1 Percent of Their Bone Mass Per Month – Equivalent to an entire year of ageing on Earth.

Radiation is Another Major concerns. Although the ISS is shielded by Earth’s Magnetosphere, astronauts on missions lasting Six months or longer reeveIVE More than 10 Times The Radiation Than What is naturally Occurring on Earth. Prolonged Exposure is Linked to Higher Cancer Risks and potential cognitive decline.

  • Body Mass and Fluids: Astronauts Lose About 20 Percent of Their Body Fluids and About 5 Percent of Their Mass While in Space.
  • Muscle: Microgravity Causes Muscle Atrophy, But Exercise for Two Hours to Day, Six Days to Week and Supplements Can Reduces Muscle Loss.
  • SKIN: Skin Thins, Tears Easily and Heals More Slowly in Space.
  • EYES: Microgravity Impairs Vision While Radiation Increases Cataract Risk.
  • DNA: Most Genes Reset AFTER Returning to Earth, But About 7 Percent Remain Disrupted.
  • Psychosomatics and cognition: Radiation May Cause Brain Damage and the onsest of Alzheimer’s Disease. SPACE DISPRUTS ORIENTATION, CAUSING MOTATION SICKNESS.
  • System cardiovascular: Blood Circulation Slows Down and Production of Red Blood Cells Decias. Cardiac Arhythmia Is Common.
  • Immune System: The Immune System Weakens. Radiation Exposure From Six Months in Space Equates to 10 Times The Annual Exposure On Earth.
  • Bones: Skeletal Deformation and Bone Loss Are Likely with 1 Percent of Bone Mass Lost Event Month. Astronauts Become Workshop Because Their Spines Expand While in Orbit.

How Does The Body Recover Back On Earth?

Returning to Earth Does Not Immedialy Undo Months of Strain On Astronauts’ Bodies. As Their Bodies Readjust to Gravity, They Experience Balance Issues, Dizziness and Weakened Cardiovascular Function.

Even Months After Landing, Not Everything Revers. They Face Long-Term Health Risks, Infectuding Cancer, Nerve Damage and Degenerative Diseases.

INTERACTIVE-HOW-BODY-RECOVERY-BACK-ON-ARCH-1742316424

  • Arrival From Space: The Spine Returns to Normal Size. Flatulence is no longer an issue, and Blood Pressure Normalises.
  • One Week Later: Motion Sickness, Disorientation and Balance Issues disappoint. Sleep Returns to normal.
  • Two Weeks Later: The Immune System Revers, and The Body Fluids Lost Are Regained. The Production of Red Blood Cells Returns To Normal.
  • ONE MONTH LATER: Muscle Reformation Is Almost and Near Pre-Flight Levels.
  • Three months late: Skin redevelopment is complete. Body Mass Returns to Earth Levels, and Problems With Eyesight No Longer Exist.
  • Six Months Later: The Risk of Bone Fractures Remains As Well as an increased Risk of Cancer. Ninety-Three Percent of Genes Return To To Normal, But 7 Percent Remain Disrupted.
