The kids at the Lilburn Activities Building learned about the Space Shuttle and NASA's James Webb Space Telescope today!!! They got to see what a Space Shuttle cockpit looked like when it was in orbit. The kids examined a piece of a space flown shuttle tire, and acted out the duties of shuttle crew members. To top it off, the kids took home Space Shuttle gliders, along with shuttle and JWST coloring pages! Special thanks to former astronaut, Terry Virts, for recording my introduction! The kids loved hearing your insights! #explorepage #space #stemeducation #spaceshuttle #JamesWebbSpaceTelescope #solarsystemambassador (at Lilburn, Georgia) https://www.instagram.com/p/Cf9Xg3AujqY/?igshid=NGJjMDIxMWI=

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

Had a fun time at Fernbank Science Center’s Space Day! #apollo6 #nasa #stemeducation #georgia #spaceflight (at Fernbank Science Center) https://www.instagram.com/p/CfPoHLaO6tG/?igshid=NGJjMDIxMWI=

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.

In about 3 weeks, I’ll be attending Astronaut Training Experience at SpaceCamp as an educator! I’m so excited! Not bad for John, the world’s biggest 12 year old. Speaking of 12, that is also the number of former and current astronauts who have attended SpaceCamp. Astronaut Kate Rubins, who is on the ISS right NOW, attended as a seventh grader. #nasa @issnationallab @iss #space #stemeducation #spacecamp #iss #huntsvillealabama #launchamerica #stem https://www.instagram.com/p/CHcDEIWjriP/?igshid=rb5zh2exe8bt
