This movie is going to be amazing! And I will be at NASA when it comes out! "HIDDEN FIGURES is the incredible untold story of Katherine Johnson (Taraji P. Henson), Dorothy Vaughn (Octavia Spencer) and Mary Jackson (Janelle Monáe)—brilliant African-American women working at NASA, who served as the brains behind one of the greatest operations in history: the launch of astronaut John Glenn into orbit, a stunning achievement that restored the nation’s confidence, turned around the Space Race, and galvanized the world. The visionary trio crossed all gender and race lines to inspire generations to dream big." - 20th Century Fox

Sensing Mars: NASA Co-Op #2 Week Nine

Running trials with the new humidity on my fluid rig showed the fruits of my labor finally ripened. This week I ran three trials to collect data determining if a small business designed Humidity Sensor makes accurate measurements. NASA collaborates with small businesses to solve problems related to upcoming missions. The small business designed this Humidity Sensor so it could measure the humidity on Mars without corroding due to the planet’s chemistry.

Using sensors that NASA is familiar with I ran trial cases to get three different data points and compared those measurements to the new sensor. I created a low humidity environment with a desiccant (drier), created a moderate humidity with ambient air and a high humidity environment with a water bubbler. Using a National Instruments cDAQ (compact data acquisition) I collected data from a thermocouple, pressure gauge and a Vaisala humidity sensor that measures dew point (the temperature at which air can no longer “hold” all of the water vapor which is mixed with it) and mixing ratio (mass of water vapor over the mass of dry air). The new humidity sensor simply gives me the parts per million (ppm) of water using it’s ultrasensitive laser absorption spectroscopy. My other sensors don’t give me a ppm value so I have to calculate it using equations from my mentors “Fundamentals of Engineering Thermodynamics” book.

Building this trial rig was a unique experience because it required knowledge in electronics to interpret the signals sent by the sensors, computer science to write the data acquisition program and VNC (Virtual Network Computing) and chemical engineering to interpret data reported and use correct thermodynamics principles and equations. Next week will be looking at the data and get tangible values about how accurate the new Humidity Sensor is.

Apollo 13 Night 

On Friday the 13th NASA interns had the awesome opportunity to watch Apollo 13th in the Historic Apollo Mission Control Room on the twentieth anniversary of the movie. What was most precious about this experience was our guest lecturers, members of the Apollo 13 missions. Norman Chaffee, Apollo 13 engineer building parts on the Saturn V rocket met us at rocket park. Chaffee took us on a grand tour of the grounded beast describing the rocket's stages, his role in development and similarities to NASA's new Space Launch System (SLS) rocket. Joining Chaffee was Frank Hughes, Apollo 13 astronaut trainer. "I don't go anywhere without my toys", he said pulling out a model of the Lunar Excursion Module (LEM) and command module. After our Saturn V tour Hughes talked with us in the Historic Mission Control about his work training astronauts, details about the Apollo 13 command module and his favorite astronaut personalities. It was an honor to hear from Chaffee and Hughes, both contributing to Apollo 13th safe return - NASA's "successful failure".

NASA Co-Op Week 12: Makers & 3D Printers

Well-being of a generation can be measured by the number of children who attend a Maker Faire. Houston's George R Brown Convention Center was filled with programmers, 3D printers,hand made creations, geeky gear and folks passionate about their ability to create. Houston Maker Faire featured 150 booths, soap makers, FIRST/ VEX robotics teams, LEGO builders and cosplay costume makers. Us NASA interns and Co-Ops set up a booth sharing about career opportunities, letting students share ideas with NASA and coloring pages with kids. Folks tried on an Apollo 11 helmet and space walk glove.

NASA Co-Op Week 10: Rocket Science Is Hard

I get frustrated with NASA asking “Why don’t we just build a rocket and go?”, looking and sounding like a doofus in a horse head. NASA Johnson and Kennedy interns met up at Cape Canaveral to watch the Atlas V launch. Visiting Kennedy Space Center reminded me about how much goes into a rocket launch, sending humans or satellites into space. Of course budget and the ability to set and maintain ten year plus political space exploration goals would speed up the process. Those variables aside I want to share what goes into a rocket launch.

Fishing For Rockets Surprisingly NASA does indeed reuse rocket parts, I thought this idea was unique to SpaceX but has been in the works for decades. Following shuttle era launches skirts of rockets and other parts were retrieved from the ocean. They would be inspected, refurbished and reused. Shuttle rocket parts will be used on the new Space Launch System (SLS). Signs labeled parts that will be used for the EM-1 Orion launch. Protective materials preventing heat damage often get reapplied to these parts. Parts of the rocket get so hot it reaches 6000 degrees Fahrenheit while others get so cold ice forms. The technology used to mix these epoxies in mid air is the same technology that coats M&Ms and Doritos. Talk about spin off technologies!

Monster Tank So you made rocket parts. Great, but how do you expect to assemble and transport something so huge? This was a problem my robotics team ran into as well. We had to make sure the robot we built would fit through the door. Once you have all the rocket parts they will be assembled in the Vehicle Assembly Building (VAB), the tallest one story building in the world at 526 feet. It takes 45 minutes for the main door to be opened. Clouds have been known to form inside the VAB and rain has fallen too. Despite how big the VAB may be when transporting one of the rockets into an assembly segment it needed to be tilted at a 45 degree angle. Upgrades are currently being made for the massive SLS. Once the rocket is assembled it is transported on the Crawler-transporter moving at a back breaking speed of one mile per hour. This transporter insures the rocket reaches the launch pad safely limiting the movement of rocket to less than a diameter of a basketball.

Blast Off Wave goodbye to your creation because it will soon launch, release its payload, tumble into the sea repeating the cycle. A successful launch is dependent of many variables including launch pad hardware, windspeed, humidity, weather, and simply fishing boats in the line of debris reentry. If launch is a go bolts the size of your lower leg explode freeing the beast from the ground. If the bolts do not successfully release the rocket don’t care, it will continue to lift off and tear its restraints off like King Kong.

Careers I have considered

DREAM JOB:

Professional writer.  Like Popular Science writer.  Or a blogger.

Biologist. Improving humans via augmentations.  Saving the world from cancer, etc.

National Geographic photographer.  Partly because of this amazing video.

Industrial designer.  Like Sir Jonathan Ive.  Still one of my dream job.  When I retire, I want to buy a giant 3-D printing machine.  I’ll dream up designs in AutoCAD, and I’ll create whatever I want.

Navy SEAL.  Scuba-diving, snorkeling, and stealthy missions via submarines are really fun.  Not so keen on the enduring-unimaginable-hardship part.

Starving artist.  Doesn’t sound so bad, except for the starving part.

Graphic designer.  Saving the Gotham City from DC Comics.

Computer scientist.  Maybe if I take Computational Mathematics, I could combine this with my love of Aerospace.

Interestingly, I’ve never felt any desire to become a doctor.  I guess I lack that section of the Indian genome.

However, I got the 'engineer' section, as I'm studying to become a Rocket scientist.  Like Tony Stark (if you're wondering, he's Iron Man.

Long time no see guys

Ever wanted to ask a NASA astronaut a question? Here’s your chance!

NASA astronaut Nick Hague will be taking your questions in an Answer Time session on Wednesday, January 15 from 12pm - 1pm ET here on NASA’s Tumblr! Find out what it’s like to live and work 254 miles above our planet’s surface. Make sure to ask your question now by visiting http://nasa.tumblr.com/ask!

Nick Hague was selected as one of eight members of the 21st NASA Astronaut class in 2013. Hague was the first astronaut from his class to be assigned to a mission which launched on October 11, 2018. Unfortunately, he and his crewmate Alexey Ovchinin, of the Russian space agency Roscosmos, were forced to abort the mission when a rocket booster experienced a malfunction shortly after the launch of their Soyuz MS-10. The aborted spacecraft landed safely. 

His first flight to the International Space Station was from March 2019 through October 2019 as a a part of the Expeditions 59 and 60 crew. Together, the crew conducted hundreds of experiments, including investigations into devices that mimic the structure and function of human organs, free-flying robots and an instrument to measure Earth’s distribution of carbon dioxide. While at the International Space Station, Hague conducted three spacewalks, totaling 19 hours and 56 minutes with a total of 203 days in space.

Nick Hague Fun Facts:

Hague was awarded the Order of Courage from the Russian Federation for his actions during the Expedition 57/58 launch abort. 

Hague was selected for the Air Force Fellows program where he was assigned as a member of the personal staff in the U.S. Senate, advising on matters of national defense and foreign policy.

He was a top flight test engineer in the U.S. Air Force.

He deployed five months to Iraq in support of Iraqi Freedom, conducting experimental airborne reconnaissance.

He enjoys exercise, flying, snow skiing and scuba.
