STEM Careers Blog – Chemistry


Chemistry is the study of matter.’ This is likely one of the first things that you will learn when you enter the lab to study for the first time. Everything on Earth is composed of matter in its vast number of forms. Chemists dedicate their lives to understanding the properties, composition, and structure of substances and how they interact with one another. The vast applications of this science enable us to break down materials to their purest forms, decode the structures and reactions of materials to progress scientific research, and develop efficient, chemically sound strategies. Chemistry has been at the forefront of scientific advancement, and its applications form the foundation for progression. Whether you're already immersed in the world of chemistry or considering it as your academic and professional destiny, join us as we unlock the doors to the remarkable career horizons that await those who dare to explore the depths of chemical science.

Chemistry in the Cosmos

While it may be hard to imagine being able to manage a chemistry lab at zero gravity, chemists have done incredible work in microgravity and in the pursuit of discovery that has opened doors for new avenues of research.  Applying the study of chemistry off-world has created new branches of study such as astrochemistry (the study of atoms and molecules in space), atmospheric chemistry (the chemistry of Earth’s atmosphere), and planetary chemistry (the study of planets and their planetary systems). Technological advancements have allowed for multiple laboratories to be implemented in orbit attached to space stations. These labs have taken research in chemistry and other STEM disciplines to new heights.

Chemistry has played a key role in the progression of space exploration and has provided solutions to problems in many notable instances.  On the mission Apollo-13, a critical oxygen tank was ignited by damaged insulated wiring causing a total depletion of oxygen for life support and propulsion systems.  The astronauts and mission control worked together with NASA Chemists to create a makeshift adaptor for the lithium hydroxide canisters to remove toxic CO2 build-up. With the filter engaged and the lunar landing canceled, engines on the lunar module were repurposed to set a trajectory back into Earth’s atmosphere. This problem-solving initiative guaranteed a safe return home for the crew.

Chemists also have a history of traveling into orbit themselves.  John Llewellyn was the first ever chemist to be selected as a NASA astronaut. He earned his Bachelor of Science in Chemistry in 1955 and his PhD in Chemistry in 1958. Llewellyn took up a professor’s position and researched at universities for a period before being chosen to be Astronaut Candidate as a scientist-astronaut by NASA in August 1967. Unfortunately, he was unable to complete his flight training and resigned in 1968.

Chemist Helen Sharman was the first British cosmonaut. After graduating with a Bachelor of Science in Chemistry from University of Sheffield in 1984 and earning a PhD in Chemistry in 1987 from the University of London, she worked in research and development for General Electric and later worked as a chemist for chocolate company, Mars. She heard a public announcement of open applications for astronaut candidates, Project Juno, on her drive home from work, jumped at the opportunity, and was selected for the mission on live television in 1989.  She flew on the Soyuz TM-12 mission to the Russian space station, Mir, which lasted eight days.  Sharman conducted multiple tests during her time in space and also spent some time practicing photography over the British Isles.

Cady Coleman, who holds a PhD in Polymer Science, spent over 180 days in space including a six-month stay on board the International Space Station (ISS).  Coleman’s first mission, STS-73, launched on space shuttle Columbia in 1995. This mission lasted over fifteen days in which extensive research was conducted in materials science, biotechnology, combustion science, and fluid physics. On STS-93, also on Columbia, she acted as Lead Mission Specialist for the deployment of the Chandra X-ray Observatory. Her longest and final mission was Soyuz TMA-20 in 2010 which lasted six months. During her extended period aboard the ISS Coleman acted as Lead Robotics and Lead Science officer.

Another Astronaut Chemist is Leland Melvin.  Melvin has logged over 565 hours in space. Before becoming a full-time Chemist, he was a football player.  Melvin attended the University of Richmond on a football scholarship where he achieved a Bachelor of Science in Chemistry.  After graduating, he was drafted in the 1986 NFL draft in the 11th round by the Detroit Lions, but suffered a hamstring injury in training camp which kept him from making his professional debut.  He was released from the Lions then signed as a free agent to the Dallas Cowboys in 1987. The same year that Melvin signed on with the Cowboys he enrolled in a program to earn his master’s degree at the University of Virginia. A second hamstring injury in training camp once again kept him off the field, and he switched gears to focus on education and earn his Master of Science in Materials Science Engineering in 1989.  Shortly after, Melvin began his work at NASA's Langley Research Center in the Nondestructive Evaluation Sciences Branch. He went on to use his specialization to lead teams until he was encouraged to apply to the astronaut program.  He was selected as an Astronaut Candidate in 1998 and flew two missions, STS-122 and STS-129, on the Space Shuttle Atlantis as a mission specialist. STS-122 launched in 2008 and focused on the delivery and installation of the European Space Agency's Columbus module for the ISS, the SOLAR observatory, and other equipment for repairs and replacements. This mission lasted over twelve days. Astronaut Melvin’s second mission, STS-129, launched to the ISS in 2009 and lasted over ten days. During the mission, the crew delivered two ExPRESS Logistics Carriers (ELC racks) and about 30,000 pounds of replacement parts for essential systems that provide power to the station to keep it from overheating and maintain proper orientation in space. On STS-129, Melvin flew with two of Higher Orbits’ partnered astronauts, Mike Foreman and Nicole Stott!
