Bacon and eggs. A bacon, lettuce, and tomato sandwich. Bacon crumbles sprinkled over roasted Brussels sprouts. Even a doughnut topped with maple icing and, you may have guessed, bacon. Hungry yet? These are all food items that have one time or another been on my menu. The common thread, of course, is the crispy, tasty addition of bacon. How does bacon go from its initial properties and appearance to the flavorful, delicious cooked product that many of us love to eat?

Science is pretty cool, especially when you get to teach it using demonstrations and hands-on experiments. Thanks to a ChemClub Community Activities Grant from the American Chemical Society (ACS), students from Westside High School in Houston, Texas were able to show the 5th grade students at Askew Elementary School just how exciting chemistry can be.
Members of the Westside High School Academic Science Demonstration Chemistry Club spent 2 months during the fall semester and 2 months during the spring semester of the 2016-17 school year planning and organizing our “Morning of Chemistry” days. Once our preparation and planning was complete we presented two morning sessions to the students at Askew Elementary School. During each morning session, students learned about electric circuits, heat transfer, pressure and temperature relationships, combustion, polymers, and chemical reactions via a series of demonstrations and hands-on activities. Students were even allowed to take home a few “souvenirs” that resulted from the activities of the day!
Because science is important in many aspects of life, it’s important to get students interested early and keep them interested throughout middle school, high school, and life after graduation. The Westside High School chemistry club hopes to create citizen scientists one demo day at a time, and with the positive feedback from our first presentations, we plan to continue these “Mornings of Chemistry” next school year.
While reading The Martian, our ACS ChemClub book study selection, it amazes me how real the story seems, even though we know humans have yet to travel to the Red Planet. But after reading the book you may have wondered how likely it is for a real mission to take place, rather that the fictional Ares Program in The Martian.
It turns out NASA is already developing the capabilities needed to send humans Mars in the 2030’s, a goal outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010. And it is not just NASA doing the planning, they are also working with commercial and international partners to create the Global Exploration Roadmap, which lays out a shared vision for coordinated human and robotic exploration of our solar system. In March 2017, the president of the U.S. signed a new law authorizing a manned NASA mission to Mars.
The plans for exploring are complex and have many steps, but two big pieces of technology include NASA’s powerful Space Launch System rocket and Orion, a new generation spacecraft designed to carry astronauts into deep space.
The Orion Spacecraft will carry a crew of four. It is capable of missions as near as orbits around the earth to as far as Mars and beyond. Orion will have multiple uses, from transporting crew and supplies to the International Space Station to exploring deep space. NASA’s current goal is to have Orion operational by 2021.
The Space Launch System is classified as a super-heavy launch lift vehicle. It initially will be able to carry 70 metric tons of payload into Earth orbit. Upgrades in years to follow will double this capacity. The first version is scheduled to launch in 2018.
The next step in going to Mars is to build the Deep Space Gateway and the Deep Space Transport. The Deep Space gateway will be like a small version of the International Space Station but will orbit around the moon. This will serve as an assembly station and rest stop for astronauts headed for Mars. It will have several docking ports and room to amass supplies and equipment.
The Deep Space Transport is a reusable spacecraft that will be stationed at the Gateway and will depart from there. After traveling to Mars it will return to the gateway for service and refitting and another mission. Other than landing humans on the surface of Mars and returning them safely, other details of the first mission to Mars are still in development.
And if you still think this sounds like science-fiction, consider that NASA has designed a series of posters to recruit the next generation of deep space voyagers! Although they are not quite ready to accept applications, they are definitely getting the word out that the future is real.

Don’t forget, about the resource packet for the ChemClub Virtual Book Club, including the two contests that are still open:
While the ChemClub Virtual Book Club is about the printed version of The Martian, it would be hard to never mention the movie version. The movie gives the characters faces and voices making it more appealing to a wider audience. We’ll explore resources for both the film and the novel in this blog post, but remember to share your thoughts with us in the comment section and on Facebook or Twitter using #ACSChemClubBook.

I don’t even remember why I chose it to read. Maybe it was random buzz on the internet. I mainly needed something to kill time on a cross-country flight. On the plane, I cracked it open. Just a few pages in, I knew it was different. An interesting science fiction story, but it was something more that appealed. It was how science and problem solving were woven directly into the plot of The Martian at nearly every turn. Continue reading “Science in Fiction”
