10 Things: Journey To The Center Of Mars

10 Things: Journey to the Center of Mars

May the fifth be with you because history is about to be made: As early as May 5, 2018, we’re set to launch Mars InSight, the very first mission to study the deep interior of Mars. We’ve been roaming the surface of Mars for a while now, but when InSight lands on Nov. 26, 2018, we’re going in for a deeper look. Below, 10 things to know as we head to the heart of Mars.

Coverage of prelaunch and launch activities begins Thursday, May 3, on NASA Television and our homepage.

1. What’s in a name?

“Insight” is to see the inner nature of something, and the InSight lander—a.k.a. Interior Exploration using Seismic Investigations, Geodesy and Heat Transport—will do just that. InSight will take the “vital signs” of Mars: its pulse (seismology), temperature (heat flow) and reflexes (radio science). It will be the first thorough check-up since the planet formed 4.5 billion years ago.

2. Marsquakes. 

You read that right: earthquakes, except on Mars. Scientists have seen a lot of evidence suggesting Mars has quakes, and InSight will try to detect marsquakes for the first time. By studying how seismic waves pass through the different layers of the planet (the crust, mantle and core), scientists can deduce the depths of these layers and what they’re made of. In this way, seismology is like taking an X-ray of the interior of Mars.

3. More than Mars.

InSight is a Mars mission, but it’s also so much more than that. By studying the deep interior of Mars, we hope to learn how other rocky planets form. Earth and Mars were molded from the same primordial stuff more than 4.5 billion years ago, but then became quite different. Why didn’t they share the same fate? When it comes to rocky planets, we’ve only studied one in great detail: Earth. By comparing Earth’s interior to that of Mars, InSight’s team hopes to better understand our solar system. What they learn might even aid the search for Earth-like planets outside our solar system, narrowing down which ones might be able to support life.

4. Robot testing. 

InSight looks a bit like an oversized crane game: When it lands on Mars this November, its robotic arm will be used to grasp and move objects on another planet for the first time. And like any crane game, practice makes it easier to capture the prize.

5. The gang’s all here.

InSight will be traveling with a number of instruments, from cameras and antennas to the heat flow probe. Get up close and personal with each one in our instrument profiles.

6. Trifecta.

InSight has three major parts that make up the spacecraft: Cruise Stage; Entry, Descent, and Landing System; and the Lander. Find out what each one does here.

7. Solar wings. 

Mars has weak sunlight because of its long distance from the Sun and a dusty, thin atmosphere. So InSight’s fan-like solar panels were specially designed to power InSight in this environment for at least one Martian year, or two Earth years.

8. Clues in the crust.

Our scientists have found evidence that Mars’ crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet’s interior structure and evolution. “The crust is the end-result of everything that happened during a planet’s history, so a lower density could have important implications about Mars’ formation and evolution,” said Sander Goossens of our Goddard Space Flight Center in Greenbelt, Maryland.

9. Passengers.

InSight won’t be flying solo—it will have two microchips on board inscribed with more than 2.4 million names submitted by the public. “It’s a fun way for the public to feel personally invested in the mission,” said Bruce Banerdt of our Jet Propulsion Laboratory, the mission’s principal investigator. “We’re happy to have them along for the ride.”

10. Tiny CubeSats, huge firsts. 

image

The rocket that will loft InSight beyond Earth will also launch a separate NASA technology experiment: two mini-spacecraft called Mars Cube One, or MarCO. These suitcase-sized CubeSats will fly on their own path to Mars behindInSight. Their goal is to test new miniaturized deep space communication equipment and, if the MarCOs make it to Mars, may relay back InSight data as it enters the Martian atmosphere and lands. This will be a first test of miniaturized CubeSat technology at another planet, which researchers hope can offer new capabilities to future missions.

hi! this is very random, but i found your tumblr just now and decided just to go for it and ask you a question about studying anthropology. I am kinda new to the whole subject, but I am interested in social studies, linguistics and the whole process called evolution. I know that the subject is so so so much more, but perhaps you would like to tell me how did you know that it was THE THING you wanted to pursue and maybe what qualities should an anthropologist have?

Hi!! You’re not random at all. It’s always good to ask questions, and I’m happy to answer any that I can! (: 

So, I think I need to start by saying that people can choose anthropology for SOOOOO many different reasons, because there are really endless things you can do with this subject (your interests are right on point though!). Personally, I originally was drawn to it because of forensic anthropology, and my love for bones, dead things, and solving mysteries. When I decided to study anthropology to go into forensics, my reason for doing so was because it was the one thing I’d studied that really…lit me up inside. Like, it felt like my neurons were firing at a million miles an hour whenever I was learning something about biological anthropology or forensics. As it turns out, I get that same feeling when studying cultural anthropology too. I ended up switching gears from forensic anthro to cultural anthropology because it is very important to me that what I do help people, and make a difference in the world. I felt like the best way to do that while still getting that ~crazy neuron party~ feeling was to study cultural anthropology and help people through my research. So…I guess the short answer to your question is that I knew it was THE THING because of how it made me feel, the way it woke up this intense curiosity in me. No other subject makes me want to devour it the way anthropology does, and I am a very curious person, so that’s saying something. It also is the perfect subject for a curious person, because you can have a bunch of different interests and somehow they all fall under the field of anthropology, so you aren’t limited by much. 

As far as the qualities, it definitely depends on the subfield, but here are a couple I feel might be most important overall:

have an interest in studying SOMETHING about humans. anthropology is literally the study of humans so that’s number one. 

be open-minded. part of studying anthropology is learning to see the world in a completely new way, and you have to be able to get out of your own head and away from your own biases to do that.

enjoy studying other cultures. no matter what you end up doing with anthropology, you’re going to need to value and enjoy learning about other people/cultures in order to be an anthropologist.

be ready for graduate school. i’m not saying you HAVE to go to grad school to be an anthropologist, but…to do most things in anthropology you’ll at least need a Master’s.

enjoy traveling. this depends on your subfield for sure, but a lot of anthropologists spend months or years at a time living in other cultures, or at dig sites, etc. because we are all about understanding things first hand.

I’m sure there are more, but those 5 seem like a good start. I hope this was helpful, and I definitely encourage you to keep looking into the field more! Don’t worry about exactly what you would want to do with it, just try to get an understanding of what anthropology is overall. If you’re in college, take a couple introductory courses that can also satisfy your gen eds. And I’m happy to answer any other questions you might have!

1945-1952 - Space Station by Wernher von Braun - Von Braun was a leading aerospace engineer first in Germany until 1945, and after being captued by U.S. forces in the same year, he continued working for NASA in U.S. He made United States able to develop the Saturn/Apollo program, making humans landing on the moon. The pictures here by NASA show one of Wernher von Braun’s fantastic plans, designing a space station for humans. NASA said that “(Wernher von Braun is) without any doubt the greatest rocket scientist in history”. For further details on the space station, please study the following link, adding a lot of details to this concept: http://www.astronautix.com/craft/vonation.htm. The following quote is as well from that website: “In the first 1946 summary of his work during World War II, Wernher von Braun prophesied the construction of space stations in orbit. The design, a toroidal station spun to provide artificial gravity, would be made very familiar to the American public over the next six years. The design was elaborated at the First Symposium on Space Flight on 12 October 1951 at the Hayden Planetarium in New York City. The design was popularized in the series in Colliers magazine, illustrated with gorgeous Chesley Bonestell painting, in 1952. The 1946 version used 20 cylindrical sections, each about 3 m in diameter and 8 m long, to make up the toroid. The whole station was about 50 m in diameter and guy wires connecting and positioning the toroid to the 8 m-diameter central power module. This was equipped with a sun-following solar collector dish to heat fluid in a ball-shaped device. The heated fluid would run an electrical generator. Presumably visiting spacecraft would dock or transfer crew at the base of the power module.”

Cotton Rat Skull

Cotton Rat Skull

My first rat skull, found it in Florida all dried up next to our condo. Judging by the fur color, fur texture, and S shaped molars I THINK its a hispid cotton rat. There were a few of these little guys running around and they didn’t look like normal rats to me. But idk, there’s really no way for me to tell for certain just by skull measurements.  I’m not quite that good at bone identification yet.

Technology for the blind!

NSF-funded researchers at Texas A&M University have developed STAAR (Situated Touch Audio Annotator And Reader) e-reader that enables blind readers to read the same text sighted readers do. The system allows a user to scan the text with their fingers to hear the words. For more information:  https://bit.ly/2Fm1HSU
