Allow us to reintroduce someone … the name’s Perseverance.
With this new name, our Mars 2020 rover has now come to life! Chosen by middle school student Alex Mather, Perseverance helps to remind ourselves that no matter what obstacles we face, whether it’s on the way to reaching our goals or on the way to Mars, we will push through. In Alex’s own words,
“We are a species of explorers, and we will meet many setbacks on the way to Mars. However, we can persevere. We, not as a nation but as humans, will not give up. The human race will always persevere into the future.”

Stowage Success: NASA Co-Op #3 Week 16
Last week at my third Co-Op tour at NASA Johnson concluded with successful handover and continuation of the stowage app. I passed on development leadership to a full-time employee after receiving green light from managers. I consider this outcome to be a mission accomplished.
After receiving feedback from non-biased data takers, I met with app developers to prioritize how to move forward with app development. As a result the development team wants to designate a point of contact to learn about stowage ops just as I have to understand what the customer, crew member, would benefit the most from. The developers plan to take the feedback to refine app functionality and interface to make it more intuitive. Additionally, after comments from users like, “what do I do next?”, implement a procedure based app and conduct more user tests after refinements with an explicit tutorial.
Following my exit pitch to management about the stowage app I was awarded a Flight Operations Challenge Coin earned by exemplifying Mission Control values during my Spring Co-Op tour with the Inventory and Stowage Officers. These values include; discipline, competence, confidence, responsibility, toughness, teamwork, and vigilance.
Res Gesta Per Excellentiam -
Achieve through Excellence
This tour has been the most challenging and enjoyable so far. This fall I will be joining OSO (Operations Support Officer) team in Mission control.
You thought volunteering at Houston FIRST Robotics Championships was enough robots for me?
WRONG
I attended the St. Louis Championship too on my way home from Houston! My "Robot" Mater the Duluth East Daredevils and local team Esko Subzero Robotics competed.
It's good that we are moving the St.Louis Championship to Detroit next year because the roof started leaking on the field! Note the plastic tarp covering part of the field.

Hello Worlds: NASA Co-Op #3 Week 15
This year launched the inaugural dual FIRST Robotics Championships in Houston and St. Louis. Before, only one Championship dubbed "Worlds" was hosted where teams around the world competed for one title. Due to the growth of the teams involved in robotics, FIRST has decided to split Worlds into a North and South Championships with the intent to bring the winning alliance form each championship to battle it out during a live televised event. Unfortunately this means a Northern team will never be able to compete against a Southern team unless they win championships or pay to attend an out of state regional earlier in the season. There was ~700 teams, 15k students and 30k attendees!
My time volunteering was fantastically frantic! Resetting the Steamworks play field after each match for the robotics teams was a challenge requiring over 400 wiffle balls be picked up and dozens of yellow gears to be stacked.
Worked on the "Newton" FRC field. Winners from this field competed in the finals held in Houston's Minute Maid Park where their Astros baseball team plays. Logistics of getting 700 robotics teams into Minute Maid was a challenge that took longer than expected. There will be time for improvement as the southern robotics championship will be held in Houston for at least three more years.
The field had to be cleared within seven minutes to keep matches on schedule.
Robotics Houston Championship concluded with the announcement of he highest award, Chairman's, earned by team Thunder Down Under from Australia and fireworks!
Even the VIP seats did not have a good view of the final matches! Growing pains but lots of opportunity to improve over the next couple of years.
It is rumored the winners of the St.Louis and Houston Championships will go head to head at the FIRST Festival of Champions July Friday 28th - Saturday 29th, 2017.

Robotics, Simulation & Future: NASA Co-Op #3 Week 8&9
Robotics: Many NASA interns and Co-Ops got hooked on STEM disciplines by participating in FIRST (For Inspiration and Recognition of Science and Technology) Robotics. In fact there is a robotics team that meets at NASA Johnson's Space Vehicle Mock Up Facility, the Robonauts. There are four levels for FIRST Robotics; Junior Lego League for ages 6 to 10 (JrFLL), Lego Robotics League for 4th to 8th grade (FLL), FIRST Tech Challenge for 7th to 12th grade (FTC), and FIRST Robotics Competition for 9th to 12th graders (FRC). There are still FIRST Robotics events you can take part in.
Search for FIRST Robotics events pick “Event” and use filters such as dates, program type, county and zip code.Volunteers apply through the Volunteer Information and Matching System and need to pass a background check. Once you are accepted into a position the volunteer coordinator will supply you with the necessary training.

Simulation: A group of us toured the Systems Engineering Simulator (SES) lab a part of NASA Johnson's Robotics Engineering division. Astronauts visit SES to practice docking Orion, capturing the SpaceX Dragon cargo ship, and driving a Mars rover. They simulate realistic physics and scenarios with in house software (Unreal Engine couldn't cut it). The have simulations with the International Space Station, Japanese Cargo Vehicle (HTV), Dragon, Cygnus, Orion and future space exploration vehicles.
Future of NASA: Center Director Ellen Ochoa, Deputy Director Mark Geyer and Associate Director Melanie Saunders hosted an All Hands where they shared with NASA Johnson employees essentially our state of the union. Ochoa described that NASA of priority and interest of the new administration. Per the request of the administration, NASA is conducting a study to weigh the risks of adding a manned crew to Space Launch System and Orion Space Craft's EM1 test. This study is expected to conclude late March.
SCIENCE PACKED WEEK: NASA Co-Op #3 Week 7
The amount of science that occurred this week was so overwhelming that I had to make the title all caps. Five major science related events occurred this week... I was a Judge at the FIRST Robotics Tech Challenge SE Texas Championship, assisted in astronaut user testing, watched a briefing about seven new Earth-like planets found, watched SpaceX Dragon cargo ship dock to the International Space Station, and trained on the job in Mission Control during the Dragon cargo ship unstow.
1. FIRST Robotics Tech Challenge Judging
FTC is like FRC (that I was in back in high school) except FTC robots are 18in x 18in x 18in, rather than 120lb robots we built, and play a different game. This year's game is Velocity Vortex which required students to build a robot in only six weeks that could lift large medicine balls and shoot Whiffle balls at a target. I had a great time at the FIRST Tech Challenge's SE Texas Regional Champs judging teams. It was a challenge to judge teams when there was so much talent to sift through! Unlike Minnesota FRC's one regional these TX FTC folks have to go through three levels of competition to get to the World Championship. Worlds will be held in Houston this year April 19-22.
Volunteer with at a FIRST Robotics event.
2. SpaceX Dragon Launch to Space Station
Launch of Falcon9 carrying dragon cargo to Space Station went wonderfully. Additionally, a stage of Flacon 9 successfully landed ON LAND back in Florida to be refurbished and reused. This private space industry/ US Government/ International effort demonstrates Scott Kelly's quote: "Spaceflight is the biggest team sport there is, and it's incredibly important that we all work together to make what is seemingly impossible possible." Kelly said this when he handed over command of the ISS to fellow NASA astronaut Tim Kopra during his Year In Space Mission in 2016. Despite public belief, spaceflight is a team collaboration (not competition) between government, private and international groups.
3. Astronaut User Testing
In parallel to hands free stowage app development I am "Project Manager-ing" for, I am helping with a similar app on an iPad. This iPad app is going through user testing to get approved and sent up to Space Station. I assisted with user testing including participants from ISO and participants from the astronaut crew office who have flown. The test participants were asked to gather items in the ISS mock-ups and pack them into the SpaceX Dragon cargo ship mock up. I was available for test participants to ask about space station locations. Additionally I made the “play” stowage items that participants gathered and packed.
4. New Earth-like Planets Found
First known system of seven Earth-sized planets has been found! This solar system is called TRAPPIST-1 and the planets are named letters "a" through "g" from closest to furthest from the Star. These planets are one hundred times closer to their star and closer to each other than the planets in our solar system. This means that on the surface of one planet you can see other planets clearly like our moon. Since this star is significantly cooler than ours which leaves three of these planets habitable despite close proximity to the star. At light speed it would take 39yrs to reach this solar system. In 2016 in Chile, researchers used the TRAPPIST telescope to find two of the planets in TRAPPIST-1. In part of a global effort NASA's Spitzer telescope found total of seven reported this week. In the future NASA's James Webb telescope, set to launch in 2018, will take a closer look at TRAPPIST-1.

5. Dragon Cargo Ship Unstow
Conducted on the job training with DISO (Dragon Inventory Stowage Officer) in a Mission Control support room. DISOs are in charge of monitoring the astronaut’s cargo unstow of SpaceX’s dragon cargo ship docked to the International Space Station. Dragon delivered many scientific experiments, food and temperature sensitive items. During unstow astronauts Peggy Whitson and Thomas Pesquet were about an hour ahead of schedule. This crew is extremely efficient and is ahead of schedule for every task, even spacewalks. Pesquet unpacked cold bags where temperature sensitive science is stored and should be unpacked quickly. Whitson retrieved CTBs (Cargo Transfer Bags) from Dragon which included science that needed kept at a particular temperature and pressure. CTBs are White, rectangular, cushiony, sewn bags sealed with a zipper and are used on every flight to contain items.
Unloading items from dragon in an elegant organized fashion is critical because SpaceX must always know its center of gravity. If there is a Dragon emergency in which case dragon cannot stay on ISS and needs to return to Earth the center of gravity is available for accurate trajectory calculations. During my on the job training I followed the procedures sent to crew and recorded changes astronauts made to the procedure. I listened to the voice loops of each of the flight control consoles communicating to each other about the astronaut’s tasks. I was able to confirm “words”, what was spoken over the loop, to the official DISO flight controller as a second check. Sometimes DISO are asked to confirm that an unstow procedure is being completed correctly and sometimes DISO needs to call the Flight Director to point out a stowage item concern.
FIRST Robotics Kick Off is THIS SATURDAY Jan7 at 9amCT!
3,400 teams made up of over 85,000 students will learn what game their robot will be playing. Within a six week build season students will have to fabricate, wire and program that robot. The game's name, "STEAMworks", has been revealed along with some vague hints. Here is a post with some of my theories and the link to watch the unveiling of the game live.
These are essential tips for FIRST Robotics teams starting build season this Saturday!
8 Ways to Stay Healthy During Build Season
Three more days until kickoff! You know what this means: pizza, caffeine, and no sleep for 42 days.
However, despite all the jokes we all make about awful diets and bad sleep habits, self-care is something we all need to remember during build season. Here are some tips to stay healthy as we approach a time when our health often, unfortunately, ends up as a low priority.
Reusable water bottles. Water is pretty important for obvious reasons, but multiple bottles of water can be tiring to lug around. Plus, it’s better for the environment than the recyclable water bottles.
Sports drinks in moderation. Although water is always a good go-to when you need to hydrate, if you’ve been sweating a lot, you also need to replenish the electrolytes you lose. Drinks like Powerade and Pocari Sweat are great for those purposes.
Don’t fall asleep in a binder. We all know how it happens: after a long day’s work, you get home, plop in bed, and pass out in grimy clothing. It’s fine. Just make sure you remove your binder if you wear one.
Utilize team sweatshirts and layers. Depending on what part of the world you live in, it can get pretty cold outside, so make sure to bundle up when traveling to and from your team’s shop. If you wear a binder, you can also use sweatshirts and larger clothing to take a break.
Fruit instead of sweets. And most snacks in general. Vitamin C prevents colds, which is extremely important when you spend a lot of time close to people in the winter. It’ll also help prevent breakouts.
Protein bars. Pizza is the solution to almost all your problems most of the time, but if you’re eating it three meals a day, that’s a problem that can’t be solved by more pizza. Protein bars are just one alternative, and a fantastic one at that.
Set an alarm for lunchtime. Speaking of eating three meals a day, you need to make sure you really have three meals a day. It also goes for anything else you need to remember at a certain time, like picking up an object, taking your meds, checking a monitor, etc. This is also useful during competition season, because it’s very easy to forget in the heat of things.
Work out. You don’t necessarily have to do any intense workouts, but doing at least one physically active thing for an hour each week serves as a good distraction from spending so much brainpower on robots every day. It will also help prevent you from passing out at competitions when you run back and forth between the pits and the stands, or when everyone gets up to do the Macarena.
Good luck, and remember: safety and your health come FIRST.

Throwback to when I captained a FIRST Robotics team and a really fun interview about my NASA Co-Op experience:

STEAMworks: Robotics Game Theories
Teaser trailer for the 2017 FIRST (For Inspiration and Recognition for Science and Technology) Robotics Competition was released late September revealing a Steampunk theme. Now is the time for my annual game conspiracy post about what I think teams can expect based on nuanced clues and veteran FIRST experience.
FLYING MINI BOTS - "Prepare to take flight!" was the closing statement of the 2017 FIRST STEAMworks Teaser video. Could minibots be coming back with quadcopter features? Minibots was a successful and entertaining aspect of the 2011 FIRST challenge Logo Motion. At the end of the Logo Motion teams' primary 120lb robot deployed smaller minibots to climb a tower. A FIRST inspired robotics competition, Collegiate Aerial Robotics Demonstration (CARD), launched at the 2011 World Championship with the hope to start a College-Level FIRST competition. According to CARD's Wikipedia page the competitions were held between 2011 and 2013. In the teaser video the flying contraptions illustrated have circular quadcopter like rioters. With the growing interest in quadcopters, drones and other flying robots it would be easier FIRST to suppliers for teams' Kit Of Parts and easier to find mentoring help from college students and companies than years prior.
STEAM (Science Technology Engineering ART and Math) - Within the past decade educators and professionals have realized that the arts do indeed belong in STEM education. FIRST appears to be adopting the trend by imagining STEAMworks. Even a paint brush is visible in the STEAMworks game logo. What would life be without music and art? (My father is a high school art teacher and both of my parents and myself play stringed instruments). The Beautility factor or engineering, when something is aesthetic while serving a purpose, is due to the blend of STEAM disciplines. FIRST could include arts in the 2017 season by adding a Beautility award, challenging teams to combine their brand with the game's theme, continue the team website competition and add scholarships to their ~200 already offered that include students in the arts.
PNEUMATICS - It would be disappointing if STEAMworks did not emphasize the use of pneumatic devices. Although water is a component that makes steam happen a water game does not seem feasible... I'm imagining teams trying to isolate electronics from water reservoirs... don't get your hopes up. Likely, FIRST will require teams to have at least one pneumatic device. In past seasons pneumatics have been used for championship winning actuators but primarily underutilized. In the teaser trailer a gauge showing 40psi was visible, a possible operating pressure for Kit of Parts pneumatics parts (that est. 1989 is the year Dean Kamen Founded FIRST).
Hopefully these theories get you excited about the upcoming season!
Kick Off Saturday, January 7, 2017 at 9:00 amCT, will update with broadcast link before 1/9/17.
