Sam Shamoun A common point of disagreement between Muslims and Christians is the Christian belief that God does take on a human form and actually became man in the person of Jesus Christ without ceasing to be God. Yet, Christians do not believe that God in his essential nature is man, but only became man at the Incarnation. According to the Holy Bible God created all things from nothing: He is before all things, and in Him all things hold together.
Space is considered an environment - an extreme environment, filled with entities that can be harmful to spacecraft. In space, there are several environmental threats that can harm materials used to create spacecraft.
These threats include ultraviolet rays and x-rays from the sun; solar wind particle radiation; thermal cycling hot and cold cycles ; space particles micrometeoroids and debris ; and atomic oxygen.
It is essential for NASA to research and understand how materials are affected by the environmental threats that exist in space. The objective of MISSE is to test the stability and durability of materials and devices in the space environment.
PECs, which are attached to the exterior of the International Space Station, are about 2-feet by 2-feet and hold a variety of materials samples and devices whose reactions in Material immaterial space are of interest. Samples are loaded onto the top surface of the trays, and then the PEC is closed to protect the samples during launch on the space shuttle," says Kim de Groh, the principal investigator for the MISSE Science program at Glenn.
The PEC is opened by the astronaut and the trays are placed back-to-back and secured, exposing the samples to the space environment.
Samples of materials are tested on the International Space Station to discover how they are impacted by exposure to space. The ram orientation is the direction in which the space station is traveling, and the wake orientation faces the direction traveled.
The zenith orientation faces away from Earth into space, while the nadir orientation faces straight down to Earth.
Each orientation exposes the samples to different space environmental factors. Once installed, the samples remain outside of the space station, exposed to the environmental threats of space for a pre-determined period of time.
Some of the experiments are active, meaning they produce and record data while still in space. Others are passive, meaning their data will be measured once they return to Earth.
Back on Earth, the effects of the space environment on each material sample are catalogued and studied. Each PEC is mounted on the exterior of the space station. Each experiment investigates how materials that are critical to space exploration are impacted by the exposure to the rigors of the space environment.
Fabric from his spacesuit is included in the Spacesuit Fabric Exposure Experiment. NASA When astronauts travel outside of a space vehicle-for a space walk outside of the space station or to explore the surface of a celestial body, such as the moon-they must wear spacesuits to protect themselves.
The fabric that is used to create these spacesuits must be able to withstand the harsh environment of space for long durations while protecting the astronauts who wear the suits. The Spacesuit Fabrics Exposure Experiment is designed to identify and evaluate the effect of long-term ultraviolet UV radiation on spacesuit fabric.
Pristine fabric, or fabric with no contaminants on it, is tested, along with dust-damaged fabrics. The experiment includes six samples of fabrics: The fabric from the Apollo 12 mission is a piece of the actual spacesuit worn by Alan Bean.
The fabric, taken from the knee of the suit, is coated with lunar dust that accumulated on the suit when Bean wore the suit on the moon in Comparing the effects of space on the historical fabrics with the effects of space on the modern fabrics will lead to a greater understanding of the efficacy of the new fabrics.
Investigating the differences between the dusted fabrics and the clean fabrics will increase the knowledge of how spacesuit fabrics perform in a realistic setting.
NASA When a spacecraft flies with humans as passengers, the spacecraft must be tightly sealed so that the air inside of the craft is breathable.
The air inside the cabin must sustain life, so tight seals that protect the air are imperative. The seal will be used where the crew module docks to another spacecraft, such as the International Space Station, and is designed to seal in the cabin air and keep it from leaking out," says Henry de Groh III, the principal investigator for the LIDS Seal Experiment.
Thirty-four samples are included in the experiment. These include elastomer O-ring samples; aluminum samples with a microinch surface finish; and RTV Room-Temperature-Vulcanizing adhesive seals. This experiment continues work begun on earlier MISSE missions, increasing and fine-tuning the knowledge of how to create the best seals that protect humans traveling in space.
Each of these samples plays an important role in creating spacecraft seals that protect life by withstanding the damage caused by exposure to space.

Did You Know? If you're burning to know the history of "ethereal," you're in the right spirit to fully understand that word's etymology. The ancient Greeks believed that the Earth was composed of earth, air, fire, and water, but that the heavens and its denizens were made of a purer, less tangible substance known as either "ether" or "quintessence.".
