Real Life Spaceship Captain

Who is this @Cmdr_Hadfield tweeting from space with such infectious enthusiasm and posting sensational pictures of Earth from orbit? His name is Commander Chris Hadfield. He is a Canadian astronaut who is currently serving as a flight engineer aboard the International Space Station. We were so charmed by his tweets that we searched out this pre-launch interview with him. He is every bit as cool on video and great at describing his mission as an astronaut.

In March, Commander Hadfield will go from flight engineer to commander of the International Space Station’s Mission 35. He will be a real life spaceship captain just as he says in the video.

“WANTED: Astronaut candidates”

*sigh*

The heading of the want ad of your dreams right? Many of us can’t think of a more prestigious job. Adventure! Exploration! Guts! Glory!

NASA recently posted just such a want ad for astronaut candidates as seen here. Even though you may not qualify (yet) and the open period to apply ended on midnight EST Friday January 27, 2012, do not despair. NASA will need to train another group of new astronauts every so often. You are bound to see a listing like this again in the future. Until that time, this is your golden opportunity to check out what NASA is looking for in an International Space Station crew member and tailor your study and career goals toward working in space.

WHO MAY BE CONSIDERED:

This announcement is open to all qualified U.S. citizens.

Okay, if you want to work for NASA in this job you have to be a U.S. citizen. However, many other countries have space programs and now there are increasing numbers of commercial space companies that will need astronauts and cosmonauts as well. Having many of the qualifications listed below for the NASA Astronaut Candidate Program will help give you the skills necessary to become an astronaut for a country other than the U.S. or as a commercial astronaut.

This guy could be your astroboss. Vrooooom, Mr. Branson, sir. Vrooooom!

JOB SUMMARY:

NASA, the world’s leader in space and aeronautics is always seeking outstanding scientists, engineers, and other talented professionals to carry forward the great discovery process that its mission demands. Creativity. Ambition. Teamwork. A sense of daring. And a probing mind. That’s what it takes to join NASA, one of the best places to work in the Federal Government.

The National Aeronautics and Space Administration (NASA) has a need for Astronaut Candidates to support the International Space Station (ISS) Program and future deep space exploration activities.

Active duty military personnel are eligible to apply for this position. In addition to applying through USAJobs, active duty military personnel must also submit their application through their respective military service. Military points of contacts can be found at Astronaut Candidate Program.

NASA says they are looking for talented professional people like engineers and scientists. You will need to study science, engineering, and mathematics in school and consider specializing in something in those fields that will be useful as an astronaut. Astrophysics, space medicine, exobiology/astrobiology, and engineering with a specialty in manned space flight are all good suggestions of careers that will make you a desirable astronaut candidate.

Military a plus, but not required. There has been a long tradition of astronauts coming from the military especially the Air Force. Military astronauts have already undergone training to endure and perform under extreme conditions like the ones they will experience as astronauts. Many have flown as high-performance aviators and have worked with cutting-edge technology during their time in the military.

DUTIES:

Astronauts are involved in all aspects of assembly and on-orbit operations of the ISS. This includes extravehicular activities (EVA), robotics operations using the remote manipulator system, experiment operations, and onboard maintenance tasks. Astronauts are required to have a detailed knowledge of the ISS systems, as well as detailed knowledge of the operational characteristics, mission requirements and objectives, and supporting systems and equipment for each experiment on their assigned missions.

In brief, you will be using special equipment to perform experiments and gather scientific data. You need to know how to operate and keep that equipment in good working order. You will know how to maintain *everything* inside and outside the space station that keeps it running normally. (or die)

Long-duration missions aboard the ISS generally last from 3 to 6 months. Training for long duration missions is very arduous and takes approximately 2 to 3 years. This training requires extensive travel, including long periods away in other countries training with our international partners. Travel to and from the ISS will be aboard the Russian Soyuz vehicle. Consequently, astronauts must meet the Soyuz size requirements, as indicated below. Additional information about the position can be found at Astronaut Candidate Program.

Frequent travel may be required. Astronauts are away from home a lot. It can be a drag.

The book Packing for Mars: The Curious Science of Life in the Void by Mary Roach relates the many reasons that being in space is stressful physically, mentally, and socially on astronauts. It’s an eye-opening book that convinced me that I would have made a terrible astronaut. (Let’s just say that I’m easily annoyed.)

(source)

You have to be in good health and in top physical shape to be an astronaut. Our bodies did not evolve to live for months in weightlessness. All of your muscles, including your heart, will atrophy in zero gravity. It’s important to blast off in peak condition. Be prepared to have to work out all of the time for your job.

QUALIFICATIONS REQUIRED:

Applicants must meet the following minimum requirements before submitting an application.

1. Bachelor’s degree from an accredited institution in engineering, biological science, physical science, or mathematics. Quality of academic preparation is important.

Notes on Academic Requirements:
Applicants for the Astronaut Candidate Program must meet the basic education requirements for NASA engineering and scientific positions, specifically: successful completion of standard professional curriculum in an accredited college or university leading to at least a bachelor’s degree with major study in an appropriate field of engineering, biological science, physical science, or mathematics.

The following degree fields are not considered qualifying:
–Degrees in Technology (Engineering Technology, Aviation Technology, Medical Technology, etc.)
–Degrees in Psychology (except for Clinical Psychology, Physiological Psychology, or Experimental Psychology, which are qualifying)
–Degrees in Nursing
–Degrees in Exercise Physiology or similar fields
–Degrees in Social Sciences (Geography, Anthropology, Archaeology, etc.)
–Degrees in Aviation, Aviation Management, or similar fields”

It is great that they included a list of degree fields that they DON’T want. Don’t waste your time with these if your goal is to be a NASA astronaut.

“2. Degree followed by at least 3 years of related, progressively responsible, professional experience OR at least 1,000 hours pilot-in-command time in jet aircraft. An advanced degree is desirable and may be substituted for experience as follows: master’s degree = 1 year of experience, doctoral degree = 3 years of experience. Teaching experience, including experience at the K – 12 levels, is considered to be qualifying experience for the Astronaut Candidate position; therefore, educators are encouraged to apply.

Over and above the 4-year bachelor degree in the right kind of science, engineering, or mathematics from #1 you must have an additional 3 years of solid professional work in your scientific, engineering, or mathematics field OR have over 1,000 hours experience in piloting jets. In other words, it would be a good plan to get a degree from a good university and then join the air force and fly advanced aircraft. Do you think you can swing that?

You can also continue your education by getting a master’s degree or PhD. However, you are only given credit for 1 year’s worth of experience for a master’s degree. Most people do their masters degree in about 2 years. If after your masters degree you go on to get a doctorate you only get 3 years in experience points. NASA appears to value practical professional success and 1,000 hours of piloting jets over advanced academic degrees.

It looks like if you are a teacher with at least 3 years of teaching kids or teenagers you qualify. However, I’d make sure that you rate in some of the other areas, as well.

IDK...piloting a jet maybe?

(source)

From the above list of criteria it sounds like the impossibly perfect candidate would be a successful engineering entrepreneur with college diploma who sold her company to fly jet fighters for the military for a while, and now teaches high school mathematics.

3. Ability to pass the NASA long-duration space flight physical, which includes the following specific requirements:

Distant and near visual acuity: Must be correctable to 20/20, each eye

The refractive surgical procedures of the eye, PRK and LASIK, are allowed, providing at least 1 year has passed since the date of the procedure with no permanent adverse after effects. For those applicants under final consideration, an operative report on the surgical procedure will be requested.

Blood pressure not to exceed 140/90 measured in a sitting position

Standing height between 62 and 75 inches.

Notes on Space Flight Physical Requirements:
Since all crew members will be expected to fly aboard the Soyuz vehicle and perform Extravehicular Activities (space walks), applicants must meet the anthropometric requirements for both the Soyuz vehicle and the extravehicular activity mobility unit (space suit). Applicants brought in for interview will be evaluated to ensure they meet the anthropometric requirements.

In addition to being an accomplished scientifically-minded professional who is also a jet pilot, you need to be healthy and have good vision. You can’t be shorter than five feet and two inches or taller than six feet and three inches. The Soyuz spacecraft will take someone as short 4’11″ per the table  at spaceref.com, so I’m assuming that the minimum of five feet and two inches requirement is necessary to wear a space suit.

(source)

Other criteria from the USAJobs listing are:

  • You will have to pass a swimming test during the first month of training.
  • You must pass periodic drug tests.
  • You must pass a background check.
  • Evaluation and training will take about 2 years before you are an astronaut.
  • If you are male, make sure you register for the draft.

If you still want to be an astronaut after reading NASA’s job listing, I strongly recommend again that you read Packing for Mars: The Curious Science of Life in the Void by Mary Roach. The book cuts through the glamor and glory of space exploration to give the reader the day-to-day challenges of the astronaut experience. It’s not all moonwalks and zero gravity hijinks. If you are one of the lucky astronauts ever chosen for a space mission, a good day will be exhausting, dirty, smelly, cramped, dangerous, and sickening. But…you, YOU will be exploring space and it will all be worth it.

Clean your room the NASA JPL way

Did you see the launch of the Mars Curiosity Rover last week from NASA at Cape Kennedy, Florida? It was awesome!

Curiosity is an exciting and important robot because its job when it gets to Mars in 8 months is to look for life there. Scientists suspect that there is some very primitive form of life on Mars, but we need to send a probe with instruments and detectors built into it to test the martian environment for evidence of life.

Curiosity probably won’t find a baby plant like Wall-E does in the movie. If life is detected it’s more likely to be a type of tiny, microscopic life. That would be great because it would be the first time that people have discovered life anywhere other than Earth.

Here’s a video animation from NASA/JPL that shows us how Curiosity will travel from Earth to Mars and what Curiosity will be doing once it lands.

Yes! It will shoot laser beams at stuff on Mars.

One of the most important things you need to keep in mind if you are building a robot that will probe another planet for life, is that you don’t want to send any Earth life with your robot probe. If your rover arrives on Mars covered in Earth germs your life detectors are going to detect life, but possibly not martian life. Or perhaps the scientists would be scratching their heads when Curiosity discovered that along with unknown alien life, Mars also has athletes’ foot. Awkward…

To send a clean spacecraft to another planet you need to build it in a clean room like this:

The above picture was the Mars Curiosity Rover’s room on Earth at the Jet Propulsion Laboratory in Pasadena, CA. Your bedroom is a pig sty compared to Mars Curiosity Rover’s room. The interesting thing about this room is that it is cleaner than cleanest place you’ve probably ever been outside of a hospital operating room. Operating rooms and JPL’s clean room are designed to have fewer than 10,000 particles of 0.5 micrometers (microns) or more in diameter in the air. Microscopic life bigger than 0.5 microns are yeast, mold, most bacteria, spores and pollen.

Hey, wait! People are bigger than 0.5 microns! They are covered cooties! How can we prevent the people working in the clean room from contaminating the spacecraft? Here’s how. Before it traveled to Florida in preparation for launch to Mars, you used to be able to watch the clean room engineers and technicians build Curiosity on the internet via a webcam. However, Curiosity is traveling to Mars at the moment so Curiosity Cam is off air. Fortunately, we have a video of JPL clean room technicians in action:

You can’t miss that the technicians are completely covered in white clean room suits. These are also known as bunny suits.

We wish they came with the ears...but...no.

(source)

The clean room suits including masks, gloves, smocks, pants, and booties are designed to keep human cooties, hair, skin cells, or whatever off the spacecraft. There are many more videos showing the assembly of Curiosity at the Jet Propulsion Laboratory clean room at YouTube. Check them out.

This NASA video from a different project shows how even pieces of paper must be wiped down front and back before they can enter a clean room, or in this case, a clean tent:

Now, think about how you would get your room clean enough to make a robot for space in there.

Don’t forget the bunny suit.

Adorable.

Bad Astronomer is BADA55 or…

…How I Learned to Stop Worrying and Love Near Earth Objects

On November 8, 2011, you probably heard or read the news that an asteroid, 2005 YU55, flew between the Earth and the Moon. If you haven’t seen it yet, here is a little animation of images of the asteroid from NASA’s Jet Propulsion Laboratory. These pictures were taken when the object was getting close to the Earth on November 7, 2011. 2005 YU55 is about the size of an aircraft carrier.

Asteroids and other near Earth objects or NEOs are a concern because when they hit the Earth they do a lot of damage. Sometimes they cause catastrophic damage. For example, a giant asteroid is theorized to have hit the Earth causing so much devastation that it caused many of the life forms on Earth at the time, including the dinosaurs, to become extinct as a result. 2005 YU55 is just one of thousands of known near earth objects or NEOs that NASA’s Near Earth Object Program and other groups are watching closely.

Did I just scare you? Sorry.

But never fear, young Earthlings, for Phil Plait the Bad Astronomer is here!

Drawing by Josh Armstrong. Color & design by Tom McKay Price

Dr. Phil Plait is an astronomer and author of Death from the Skies!: These Are The Ways The World Will End. In this book he pretty much lists many of the ways that the universe in which we live can kill us and the odds of these events happening. Fortunately, the odds of these things happening in our lifetime are fairly low. (phew) Unfortunately, there is still a chance. So it’s a good idea for us to find things like near Earth objects that might some day hit the Earth and figure out a way to prevent them from turning our planet into a lifeless, molten ball of fiery lava. (whimper)

Phil Plait comes to the rescue by outlining a plan for preventing asteroid impacts in his awesome Ted Talk here.

Thanks, Bad Astronomer! You’ve saved the day!

Phil Plait writes the Bad Astronomy blog here. Almost every day, he points out new wonders of astronomy including gorgeous images of the universe and planetary aspects of the Earth.

By the way, ted.com is a site that is full of great, cutting-edge ideas in science and many other topics from the most brilliant people in a variety of fields. I encourage everyone to browse TED and enjoy the videos for their progressive and inspiring messages.
