For as long as humanity has been looking up at the sky, we’ve wondered what lay beyond the ground beneath our feet. When the astronauts of the Apollo 11 mission took their first steps in 1969, the world saw a future filled with spaceships and rockets. We dreamed of a lack of gravity, fueled by grainy images on a TV and the words of Neil Armstrong: “That’s one small step for a man, one giant leap for mankind.” The Apollo 17 mission in 1972 was the last trip to the moon for several decades.
Lunar science has become a thriving field of study which helps to define our knowledge of the formation of the universe. The lunar rock and soil samples gathered by Apollo astronauts are still studied to this day.
You arrive at a large field, small sprouts peeking out of the soil. At the center of the field lies a structure connected to a span of pipe from which sprinklers hang. Trusses brace and support its weight. From the air, this field would appear to be a perfectly circular patch of green.
Center pivot irrigation systems are one of many ways to distribute water to crops. As its name suggests, this method involves rotating around a central pivot point. When the machine rotates, it releases water from the sprinklers and irrigates crops. (Agrivi.com) By using this system, farmers can ensure a uniform application of water across an entire field.

In many industrial processes, the materials and the end product or by-products of the process, such as dust or vapors, can create conditions for a hazardous environment. Processes that have potential for hazardous environments include: water treatment, oil drilling, gas and chemical processing, power generation, pharmaceutical, and food manufacturing. The measurement and control of these processes are essential in maintaining optimal conditions of the manufacturing system and preventing catastrophic events.

There are many manufacturing processes that require human operators to perform tasks, which can create hazardous levels of particulate, fumes, gases, vapors, and mists. A few of these processes include: welding, sanding, grinding, brazing, laser cutting, tempering, and quenching. The Occupational Safety and Health Administration (OSHA) has regulatory requirements to reduce worker’s exposure to these hazards, which can cause respiratory and other health issues. Downdraft tables are workstations designed to better protect the operators who perform these tasks, in a bench top setting, by removing the hazardous material that laden the air from the worker’s breathing zone.
