Space captures the imagination of millions even to this day. As we learn more, space becomes increasingly vast and wondrous. There are some who dedicate their lives to the exploration...
Space Sciences Articles
While not a new subject, space science has definitely gone through some drastic changes recently (well, in the last century or so at least). It now involves not just looking into space from the comfort of Earth, but also sending out probes and even people. Whether observational, theoretical, or practical in application, space science is expanding in countless ways. The space sciences articles in this category can help you stay up to date on new developments, as well as learn about past discoveries and the methods behind modern space science.
Branches of Space Science
Space science is so vast that it includes many branches covering dozens of specialties. The following are some broad branches that cover the larger areas of the field.
Humans have been looking up to the stars for most of history, making astronomy one of the oldest natural sciences in the world. It started off as a means to create calendars for ancient civilizations or navigate the seas by way of the stars. It has now grown to a vast field that consists of astrophysics, stellar astronomy, galactic astronomy, and more. The branch of observational astronomy uses observatories, telescopes, probes and rovers to gather data from space for analysis. The theoretical branch, on the other hand, uses scientific principles to create models of objects and phenomena in space. Space sciences articles on this topic often focus on the bigger picture of space.
Many of the branches within space science are very interdisciplinary. Planetary science, for example, overlaps greatly with Earth science and the physical aspects it studies. Articles on planetary science might cover topics about the Earth itself, as well as any other planet or planetary body. This could include moons, asteroids, gas giants, and entire planetary systems. The topics of interest in space sciences articles concerning planetary science are how these bodies formed, how they evolve over time, the resources they hold, and other physical aspects of them. As Earth-bound creatures, we have a special affinity for this subject that might help us find new planets to one day call home.
Another interdisciplinary field, astrochemistry, studies the overlap of astronomy with chemistry. It studies the various molecules in the universe and how they interact with one another and with radiation, primarily through the use of spectroscopy. Using this method, astrochemists can infer properties of objects and phenomena in space such as their elemental abundances and temperatures. Due to advancements in the field, many new molecules have been discovered. We have also been able to learn about the compositions and interactions of materials all over the universe. This allows us to understand how everything formed in the past and how it could all change in the future. Combine the space sciences articles in this category with those in the chemistry category for a hybrid experience!
Aerospace Engineering (aka Rocket Science)
With a more hands-on approach, aerospace engineering tackles the practical matter of making spacecraft to explore space. The field also includes aircraft, as it started with the engineering of aviation methods. But it has since progressed to using advanced astrodynamics, materials science, and other mechanics for creating the machines that we use to explore and analyze space. Some of these machines, such as rovers and probes, venture into space alone to collect data that we analyze from Earth. Others, such as the International Space Station and the Space Shuttle, carry humans into space for direct exploration. Checking out the engineering articles in addition to these space sciences articles might give even more insights.
The Science of Humans and Life in Space
Space science started with looking up to the stars, and probably always included the urge to reach for them. However, it hasn’t been until recently that this was really an option. Space exploration is increasingly a part of space science. It started with probes, then animals were sent up to test the waters, and then humans finally made the leap. Now, we’re starting to think about what will be necessary for future generations to move away from the Earth through colonizing other planetary bodies.
One of the biggest current areas of interest is the growing possibility of Mars colonization becoming a reality. Moving to Mars or one of the other water- or ice-bearing rocky bodies in the solar system is the logical next step for the human race. If we wish to survive long term in the solar system and beyond, we need to expand beyond this planet.
It is crucial to not only consider how to get to other planets, but also how to settle on them. Common concerns of explorers on Earth are once again big areas of research in space science. We are studying how to treat medical problems in space and on other planets and how to make the medicine; how to have sustainable agriculture, and how to maintain physical health on other planets; how to help humans physically and mentally tolerate long space journeys, etc.
Getting Involved in the Space Sciences
The space sciences articles in this category can both help you learn for fun, and for career goals. They keep professionals up to date, or pair well for studying in tough college courses. After all, practically all of the sub-fields in space science require advanced education. Getting a bachelors in a core natural science such as physics or chemistry is probably sufficient, but should be followed by more specialized master’s and/or PhD programs. Such highly specialized education on such a difficult topic is likely to lead to appropriately high pay and job security.
Outside of school, there are other ways to involve yourself in keeping up with current news, events, and activities. Other than Direct Knowledge, you can get quality reading material from sources such as Astronomy, Planetary Report, and Air & Space. Also check out local organizations and clubs you can join for activities such as building rockets or stargazing. These are especially helpful for encouraging kids to explore a rich and exciting field that may lead them to great hobbies or even careers in the future.
