New Boots for Walking on Mars

 

Image

How will future space suits differ from the current ones? As space is explored, footwear for astronauts is keeping pace. NASA claims their new soft boots are designed for real walking.

Currently, astronauts don’t “walk” in space. They hover and float, or their feet are placed into foot restraints so they don’t drift away. Space suits are somewhat flexible; they can bend at the knees and rotate at the waist. But no nuanced space shuffles or relay races quite yet.

Ever ahead in their thinking, NASA envisions that astronauts will go to Mars one day. With that prospect, they need to be suited up to explore alien terrain on foot or in their vehicles. NASA’s soft boots will take them there.

Staying Physical Fit in Space

Image

Maintaining strong muscles is a big enough challenge on Earth. It is much harder to do in space where there is no gravity. 

So, how do astronauts stay fit in space? They can’t simply lift dumbbells. To minimize the physiological effects of microgravity, NASA has equipped the International Space Station (ISS) with specialized fitness equipment:

  • COLBERT –  a space treadmill  
  • CEVIS –  a stationary bike
  • ARED –  a device that simulates weightlifting

Astronauts spend up two-and-a-half hours a day working out on the ISS. Even with this regime, those who spend long periods in space return to Earth with muscular atrophy, cardiovascular deconditioning, and bone loss that can be difficult to reverse. According to NASA, 180 days in space can decrease:

  • muscular strength by 11 to 17 percent
  • muscular endurance by 10 percent
  • bone mineral density by two to seven percent.

Overcoming Fear before Walking in Space

Image

As a young Canadian boy, Chris Hadfield had dreamt of becoming an astronaut and walking in space. Before realizing this goal, he had to confront his very real fear of danger. Now a retired astronaut, Chris Hadfield reminisces about his experience:

“I was outside on my first spacewalk when suddenly my left eye slammed shut and was in great pain – some substance had leaked into it, and it had gone blind. I thought, ‘Well, maybe that’s why we have two eyes.’ So I kept working, but unfortunately without gravity, tears don’t fall. You just get a bigger and bigger ball of whatever got into your eye mixed with your tears until the surface tension takes it across the bridge of your nose like a tiny waterfall into your other eye. Now I was completely blind outside the spaceship.”

Using a bizarre ‘walking’ strategy, Hadfield had trained for this face-to-face encounter with danger. He offered details at the TED Conference in Vancouver.  Check the link below for his recommended training on how to overcome fear.

What Was the First Spacewalk Really Like?

 

Image

About six and a half hours after the landing, Neil Armstrong opened the hatch of the four-legged lunar module and slowly made his way down the ladder to the lunar surface. His initial footprint was photographed. A television camera followed his every step.

Buzz Aldrin joined Neil Armstrong on the moon surface.  The men bounded like kangaroos in the low lunar gravity, one sixth that of Earth’s.

The moonwalk lasted 2 hours and 19 minutes, long enough to let the astronauts test their footing in the fine and powdery surface — Mr. Armstrong noted that his boot print was less than an inch deep.

Human footsteps are noiseless on lunar soil; never to be erased for perhaps a million years.

Announcing the First Footstep on the Moon

Image

 “That’s one small step for man, one giant leap for mankind.”

July 20, 1969: Neil Armstrong became the first man to step foot on the moon. He and his co-pilot, Col. Buzz Aldrin planted an American flag on the lunar surface and a plaque which reads, “Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

Walking Down the Aisle

CONGRATULATIONS TRISTAN AND REBEKAH

To Honour Your Wedding May 17, 2014…

 

“The flowers in my hand tremble as I walk down the aisle.

Through watery eyes I’m seeing you smile.

Lifting me up – presenting me clean

Reflecting God’s love and His covenant to thee.

Bring Him honor and glory with our most sacred vow –

Love each other as only God will allow.

Sweet things of these – a reflection of love

‘Tween husband and wife – a gift from above.

By the grace of our shepherd sweet peace do we find

And the glory and honor of our Father, most high.

I’m seeing His promise in your eyes, so sweet

That though we may stumble, if in Him do we seek –

Our path will be true, our hearts will be sure

And our love will reflect our Father, so pure.”

 

Covenant to Thee’, written by Jody Gomez
