The Apollo 6 CM is displayed not too far from where I live. I have visited it many times.

Just having a little fun. I saw an ad for kid astronaut portraits. I thought to myself, “Who’s the biggest kid you know?”
Why, me of course!

Gravity, Hazard of Alteration

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized some of the hazards astronauts will encounter on a continual basis into five classifications.

The variance of gravity fields that astronauts will encounter on a mission to Mars is the fourth hazard.

On Mars, astronauts would need to live and work in three-eighths of Earth’s gravitational pull for up to two years. Additionally, on the six-month trek between the planets, explorers will experience total weightlessness. 

Besides Mars and deep space there is a third gravity field that must be considered. When astronauts finally return home they will need to readapt many of the systems in their bodies to Earth’s gravity.

To further complicate the problem, when astronauts transition from one gravity field to another, it’s usually quite an intense experience. Blasting off from the surface of a planet or a hurdling descent through an atmosphere is many times the force of gravity.

Research is being conducted to ensure that astronauts stay healthy before, during and after their mission. Specifically researchers study astronauts’ vision, fine motor skills, fluid distribution, exercise protocols and response to pharmaceuticals.

Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight, including gravity.

Or, check out this week’s episode of “Houston We Have a Podcast,” in which host Gary Jordan further dives into the threat of gravity with Peter Norsk, Senior Research Director/ Element Scientist at the Johnson Space Center.

This arrived in the mail the other day. Nice touch! Proud to be a part of such a wonderful space science family! @spacecampusa @spacecampalumni @rocketcenterusa #stem #space #nasa #huntsvillealabama @visithuntsvilleal https://www.instagram.com/p/CML70GGjfrM/?igshid=ot9ckg0kfkg5

It’s gonna be a long night! I’m super excited to be at @kennedyspacecenter for the Artemis 1 Launch! The launch is scheduled for 8:33am local. There will be a two hour window. If it doesn’t launch tomorrow, the next window is September 2, 2022. . . . . . #explorepage #artemis #artemisgeneration #stem #nasasls #SLS #orion #wearegoing #nasaexploration #solarsystemambassadors (at Kennedy Space Center Visitor Complex) https://www.instagram.com/p/Ch09ZFquI_l/?igshid=NGJjMDIxMWI=

Just found out my GOES-16 (formerly GOES-R) certifications qualify me for projects on GOES-S! My “midlife crisis” hobby is really starting to “blast off”. 😏🌎🛰

My @lucy_mission shirt arrived! LUCY has just started a 12 year mission to 8 different asteroids! Each asteroid visited will provide more clues to the beginning of our solar system. #stem #nasa #solarsystemambassador #lucyinthesky #lucy https://www.instagram.com/p/CVUHlc_sXbB/?utm_medium=tumblr
