Big Day In Space: NASA Co-Op #3 Week 12
Spacewalk
An International Space Station spacewalk with a runaway micrometeorite shield and SpaceX landing of a rocket which has already flown in space marks a busy week in space exploration.
American NASA astronaut Peggy Whitson conducted her eight spacewalk March 30th, 2017. Logging an accumulative 59 spacewalk hours, Peggy has surpassed the current record of female spacewalk hours. Peggy is now the third most experience spacewalker behind Anatoly Solovyev (68 hours) and former astronaut Mike Lopez-Alegria (67 hours). Accompanying Peggy on the spacewalk was current Space Station commander Shane Kimbrough.
The goals of the spacewalk included reconnecting cables and electrical connections to PMA3 on the Harmony node. Peggy and Shane also installed an upgraded computer relay box on Space Station's truss and installed shields to PMA3 and common berthing mechanism.
During the spacewalk, one of the shields was inadvertently lost. Fortunately, the shield floated away safely and does not pose a threat to Space Station nor the crew. However, the device missing a shield still needed to be protected. Mission Control engineers jumped into action with an Apollo 13-esque energy to solve how to replace the cover. They devised a plan for the astronauts to finish covering the port with the PMA-3 cover Whitson removed earlier in the day.
Leading this effort from the ground included light Director Emily Nelson and Capsule Communicator (CAPCOM)/Astronaut Anne McClain. Below you can see circled in green CAPCOM McClain & circled in purple Flight Director Nelson.
SpaceX Reusable Rocket
Falcon 9 rocket will delivered a commercial communications satellite to a Geostationary Transfer Orbit (GTO). SpaceX is on the road to full and rapid reusability as the world’s first reflight of an orbital class rocket, whereas NASA's Shuttle was a human transport between Earth and Space Station. Falcon 9’s first stage was previously supported a mission in April of 2016.

Potato Challenge
Today is the Martian Potato Challenge were for 24 hours you can only eat potatoes and water. However throughout the day there are opportunities to win salt, coffee and tea. Why on Earth would I be putting myself through this? It is a campaign to raise money for kids to attend space camp during Minnesota's Give To The Max Day. Although it may be too late to get in on the competition (as you eat a piece of pizza) you can still donate to the cause here...

Looking Forward to Defrag 2014
Drones, APIs, and Raspberry Pi, Defrag 2014 is a unique tech conference which the coordinators describe "explores the frontiers of technology's intersections with society". Recently I was granted a scholarship, sponsored by True Ventures, to attend Defrag in snow capped mountainous state of Colorado. Thousands of the scientifically savvy will be gathered at Omni Interlocken Resort to take part in a two day tech intensive filled with keynote speakers, break outs, and networking galore. Representatives of big name companies like IBM, Microsoft, Google, Dell, and AT&T will be attending. Aside from from my anticipation of the innovative atmosphere, I am excited to attend keynotes with the names "Robots Take Flight", "Monkey Selfies and Other Conundrums: Who Owns Your Data?", and "Can you Handle the Big Data Explosion?" name just a few. With pen, legal pad, and ideas to contribute I am ready for Defrag 2014 to blow my mind.
Where does the word defrag come from?
Defrag is short for defragmentation. When a file is stored in memory, space which that file takes up may not necessarily be continuous. Meaning, pieces of the file could be stored in chunks separate from each other. Defragmentation matches the pieces that correspond to one another and puts them next to each other. This makes retrieving files faster.
How can I get in on the action?
Throughout both days I will be blogging about my experience which you can follow here. Defrag has their own Twitter tag #defragcon which will provide updates on happenings during the conference. Check out Defrag: http://www.defragcon.com/2014/
Master Research & Development - Learn LabVIEW
LabVIEW is a graphical programming language introduced to most via FIRST Robotics, an intro to computer science class or because a past engineer used it in your workplace. Characterized by its code blocks logically stringed together with wires LabVIEW has been shrugged off and abandoned for "adult" non-graphical languages. I too thought my days of dragging and dropping would be limited to troubleshooting retired FIRST robots. After a number of internships featuring leading edge research and development projects controlled by LabVIEW I decided to reconsider my neglectful relationship with the language.
Brains of a NASA prototype deep space habitat's power system is controlled by a National Instrument's C-RIO programmed with LabVIEW. I started to realize LabVIEW was no joke. LabVIEW was used once again to prototype an Orion-like space craft display and process commands from sibling systems. Energy conversion systems for NASA's ISRU (In-Situ Resource Utilization) are controlled by sophisticated LabVIEW code following software engineering frameworks such as the "Actor Framework". During my NASA experiences I learned that LabVIEW was no joke and could be used for cutting edge research and development (R&D).
Top skills to learn in LabVIEW to become an effective R&Der include user interface design, control and data collection.
Interface Design
LabVIEW enables the ability to create graphical user interfaces (GUIs) of your controls as you drag and drop code. While you work on the backend "Block Diagram" focusing on logic LABVIEW creates a user interface you can personalize later for the user. The default GUIs may not be the prettiest but there are plenty of opportunities for customization. LabVIEW user interface tutorial. How to customize user controls.
Control
Using software engineering mantras or simple case structures your control design system can be complex or simple with LabVIEW. As you create a loop function by actually drawing a loop around code and deciding the order of code execution by drawing a wire between code blocks you will find it is quite intuitive. LabVIEW doesn't offer control unique from any other language, rather how you visualize the control. Series of videos to familiarize yourself with control structures in LabVIEW.
Data Collection
National Instruments has devices that work for plug and play data collection. Their CDaq device you plug sensors into and then recognized by LabVIEW. CDaq's code block in LabVIEW allows you to connect with a wide array of sensors, send sensor data to an Excel sheet, enter raw data into formulas, and more. Within an hour a data collection program could be thrown together for fast data collection. Video on LabVIEW data collection.
If you want do some R&D, to slap together a system to test out and work out kinks in a design LabVIEW is a quick tool to use. I am not affiliated or endorsed by National Instruments. This post is an advice piece, not an endorsement.
Intern Week 8: Pool, Control & Opportunity
Neutral Buoyancy Lab Tour A familiar faint smell of chlorine wafted in the air as we entered the Sonny Carter Training Facility. We stared at a vat containing 6.2 million gallons of water, enough to fill nine Olympic swimming pools. Looking into the lagoon, 1:1 scale International Space Station (ISS) mock-ups were resting 40 feet below. Divers went about their daily routine escorting astronauts to various modules. Astronauts practiced EVAs (Extra Vehicular Activities) learning how to repair parts of the modules. Divers would retrieve tools astronauts drop and hold a camera up to their work for instructors to see. We saw where practice EVA suits are assembled and where modules are constructed before being submerged.
Mission Control Once again we return to Current and Historic Mission Control. Apollo 11 and 13 were among the great missions flown with less computing power than your smart phones. Controls were analog and sending messages via pneumatic tubes was common.
NASA Co-Op This week I was accepted into NASA Johnson Space Center's Pathways Internship Program, what NASA calls their Co-Op program. What does this mean? I will be sworn in as a U.S. Government civil servant and switch between semesters studying Electrical Engineering and Computer Science at the University of Minnesota Duluth and working at NASA. My NASA updates will continue throughout my experience.
Today is the 30th anniversary of the Challenger Disaster. During my time as a NASA Co-Op I learned that this tragedy and lessons from Apollo 1 and Columbia are a integral part of training for new employees. We heard speakers tell their story about where they were that day, what role they had in the mission and how NASA can improve. We learned every choice we make in the design, fabrication and deployment of a space bound creation can effect the whole mission. This heightened culture of awareness emphasizes safety to next generation engineers. My thoughts will be with the astronauts who made the ultimate sacrifice, their families, and folks across aerospace agencies striving to carry their legacy.
