Chemical Space Gardens

You know that colorful crystal garden you grew as a kid?

Yeah, we do that in space now. 

Chemical Gardens, a new investigation aboard the International Space Station takes a classic science experiment to space with the hope of improving our understanding of gravity’s impact on their structural formation.

Here on Earth, chemical gardens are most often used to teach students about things like chemical reactions.

image

Chemical gardens form when dissolvable metal salts are placed in an aqueous solution containing anions such as silicate, borate, phosphate, or carbonate.

Delivered to the space station aboard SpaceX’S CRS-15 cargo mission, the samples for this experiment will be processed by crew members and grown throughout Expedition 56 before returning to Earth.

Meet Our New Flight Directors!

We just hired six new flight directors to join a unique group of individuals who lead human spaceflights from mission control at our Johnson Space Center in Houston.

A flight director manages all human spaceflight missions and related test flights, including International Space Station missions, integration of new American-made commercial spacecraft and developing plans for future Orion missions to the Moon and beyond. 

Only 97 people have served as flight directors, or are in training to do so, in the 50-plus years of human spaceflight. That’s fewer than the over 300 astronauts!
We talked with the new class about their upcoming transitions, how to keep calm in stressful situations, the importance of human spaceflight and how to best learn from past mistakes. Here’s what they had to say…

Allison Bollinger

Allison is from Lancaster, Ohio and received a BS in Aerospace Engineering from Purdue University. She wanted to work at NASA for as long as she can remember. “I was four-and-a-half when Challenger happened,” she said. “It was my first childhood memory.” Something in her clicked that day. “After, when people asked what I wanted to be when I grew up, I said an astronaut.” 

By high school a slight fear of heights, a propensity for motion sickness and an aptitude for engineering shifted her goal a bit. She didn’t want to be an astronaut. “I wanted to train astronauts,” she said. Allison has most recently worked as at our Neutral Buoyancy Lab managing the daily operations of the 40-ft-deep pool the astronauts use for spacewalk training! She admits she’ll miss “the smell of chlorine each day. Coming to work at one of the world’s largest pools and training astronauts is an incredible job,” she says. But she’s excited to be back in mission control, where in a previous role she guided astronauts through spacewalks. 

She’s had to make some tough calls over the years. So we asked her if she had any tips for when something… isn’t going as planned. She said, “It’s so easy to think the sky is falling. Take a second to take a deep breath, and then you’ll realize it’s not as bad as you thought.”

Adi Boulos

Adi is from Chicago, Illinois and graduated from the University of Illinois Urbana Champaign with a BS in Aerospace Engineering. He joined us in 2008 as a member of the very first group of flight controllers that specialize in data handling and communications and tracking systems aboard the space station. 

Most recently he served as the group lead in the Avionics Trainee group, which he loved. “I was managing newer folks just coming to NASA from college and getting to become flight controllers,” he said. “I will miss getting to mentor them from day one.” But he’s excited to start his new role alongside some familiar faces already in mission control. “It’s a great group of people,” he said of his fellow 2018 flight director class. “The six of us, we mesh well together, and we are all from very diverse backgrounds.” 

As someone who has spent most of his career supporting human spaceflight and cargo missions from mission control, we asked him why human spaceflight is so important. He had a practical take. “It allows us to solve problems we didn’t know we had,” he said. “For example, when we went to the moon, we had to solve all kinds of problems on how to keep humans alive for long-duration flights in space which directly impacts how we live on the ground. All of the new technology we develop for living in space, we also use on the ground.”

Marcos Flores

Marcos is from Caguas, Puerto Rico and earned a BS in Mechanical Engineering from the University of Puerto Rico and an MS in Aerospace Engineering from Purdue University. Spanish is his first language; English is his second. 

The first time he came to the Continental US was on a trip to the Kennedy Space Center in Florida as a kid! “I always knew I wanted to work for NASA,” he said. “And I knew I wanted to be an engineer because I liked to break things to try to figure out how they worked.” He joined us in 2010 as an intern in a robotics laboratory working on conceptual designs for an experimental, autonomous land rover. He later transitioned to the space station flight control team, where he has led various projects, including major software transitions, spacewalks and commercial cargo missions! 

He shares his new coworkers’ thoughts on the practical aspects of human spaceflight and believes it’s an expression of our “drive to explore” and our “innate need to know the world and the universe better.” But for him, “It’s more about answering the fundamental questions of where we come from and where we’re headed.”

Pooja Jesrani

Pooja graduated from The University of Texas at Austin with a BS in Aerospace Engineering. She began at NASA in 2007 as a flight controller responsible for the motion control system of the International Space Station. She currently works as a Capsule Communicator, talking with the astronauts on the space station, and on integration with the Boeing Starliner commercial crew spacecraft. 

She has a two-year-old daughter, and she’s passionate about motherhood, art, fashion, baking, international travel and, of course, her timing as a new flight director! “Not only have we been doing International Space Station operations continuously, and we will continue to do that, but we are about to launch U.S. crewed vehicles off of U.S. soil for the first time since the space shuttle in 2011. Exploration is ramping up and taking us back to the moon!” she said.” “By the time we get certified, a lot of the things we will get to do will be next-gen.”  

We asked her if she had any advice for aspiring flight directors who might want to support such missions down the road. “Work hard every day,” she said. “Every day is an interview. And get a mentor. Or multiple mentors. Having mentorship while you progress through your career is very important, and they really help guide you in the right direction.”

Paul Konyha

Paul was born in Manhasset, NY, and has a BS in Mechanical Engineering from Louisiana Tech University, a Master’s of Military Operational Arts and Science from Air University, and an MS in Astronautical Engineering from the University of Southern California. He began his career as an officer in the United States Air Force in 1996 and authored the Air Force’s certification guide detailing the process through which new industry launch vehicles (including SpaceX’s Falcon 9) gain approval to launch Department of Defense (DoD) payloads. 

As a self-described “Star Wars kid,” he has always loved space and, of course, NASA! After retiring as a Lieutenant Colonel in 2016, Paul joined Johnson Space Center as the Deputy Director of the DoD Space Test Program Human Spaceflight Payloads Office. He’s had a rich career in some pretty high-stakes roles. We asked him for advice on handling stress and recovering from life’s occasional setbacks. “For me, it’s about taking a deep breath, focusing on the data and trying not to what if too much,” he said. “Realize that mistakes are going to happen. Be mentally prepared to know that at some point it’s going to happen—you’re going to have to do that self-reflection to understand what you could’ve done better and how you’ll fix it in the future. That constant process of evaluation and self-reflection will help you get through it.”

Rebecca Wingfield

Rebecca is from Princeton, Kentucky and has a BS in Mechanical Engineering from the University of Kentucky and an MS in Systems Engineering from the University of Houston, Clear Lake. She joined us in 2007 as a flight controller responsible for maintenance, repairs and hardware installations aboard the space station. 

Since then, she’s worked as a capsule communicator for the space station and commercial crew programs and on training astronauts. She’s dedicated her career to human spaceflight and has a special appreciation for the program’s long-term benefits. “As our human race advances and we change our planet in lots of different ways, we may eventually need to get off of it,” she said. “There’s no way to do that until we explore a way to do it safely and effectively for mass numbers of people. And to do that, you have to start with one person.” We asked her if there are any misconceptions about flight directors. She responded, “While they are often steely-eyed missile men and women, and they can be rough around the edges, they are also very good mentors and teachers. They’re very much engaged in bringing up the next generation of flight controllers for NASA.”

Congrats to these folks on leading the future of human spaceflight!

AI, Cancer Therapy and Chemical Gardens Headed…

A new batch of science is headed to the International Space Station aboard the SpaceX Dragon on the company’s 15th mission for commercial resupply services. The spacecraft will deliver science that studies the use of artificial intelligence, plant water use all over the planet, gut health in space, more efficient drug development and the formation of inorganic structures without the influence of Earth’s gravity. 

Take a look at five investigations headed to space on the latest SpaceX resupply:

Plants regulate their temperature by releasing water through tiny pores on their leaves. If they have sufficient water they can maintain their temperature, but if water is insufficient their temperatures rise. This temperature rise can be measured with a sensor in space.

ECOSTRESS measures the temperature of plants and uses that information to better understand how much water plants need and how they respond to stress.

Spaceflight has an on impact many bodily systems. Rodent Research-7 takes a look at how the microgravity environment of space affects the community of microoganisms in the gastrointestinal tract, or microbiota.

The study also evaluates relationships between system changes, such as sleep-wake cycle disruption, and imbalance of microbial populations, to identify contributing factors and supporting development of countermeasures to protect astronaut health during long-term missions, as well as to improve the treatment of gastrointestinal, immune, metabolic and sleep disorders on Earth.

Cardiovascular diseases and cancer are the leading causes of death in developed countries. Angiex Cancer Therapy examines whether microgravity-cultured endothelial cells represent a valid in vitro model to test effects of vascular-targeted agents on normal blood vessels.

Results may create a model system for designing safer drugs, targeting the vasculature of cancer tumors and helping pharmaceutical companies design safer vascular-targeted drugs.

Chemical Gardens are structures that grow during the interaction of metal salt solutions with silicates, carbonates or other selected anions. Their growth characteristics and attractive final shapes form from a complex interplay between reaction-diffusion processes and self-organization.

On Earth, gravity-induced flow due to buoyancy differences between the reactants complicates our understanding of the physics behind these chemical gardens. Conducting this experiment in a microgravity environment ensures diffusion-controlled growth and allows researchers a better assessment of initiation and evolution of these structures.

These investigations join hundreds of others currently happening aboard the orbiting laboratory.

A sextant is a tool for measuring the angular altitude of a star above the horizon and has helped guide sailors across oceans for centuries. It is now being tested aboard the International Space Station as a potential emergency navigation tool for guiding future spacecraft across the cosmos. The Sextant Navigation investigation will test the use of a hand-held sextant that utilizes star sighting in microgravity.

Astronaut Journal Entry – To Touch the Stars

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry, written in space, by NASA astronaut Scott Tingle.

To read more entires from this series, visit our Space Blogs on Tumblr.

This is my last entry into the Captain’s Log. Drew Feustel, Ricky Arnold and Oleg Artymyev are now in charge after an excellent change of command ceremony where Drew took command of the International Space Station (ISS). We, the crew of the Soyuz MS-07 spacecraft, will undock from the International Space Station on Sunday morning (3 June), reenter the earth’s atmosphere and land on the steppe of Kazakhstan. I will be reunited with my family 24 hours later in Houston, and then begin recovery for living on Earth….with gravity….ugh.  

I would like to thank all of you for following along on this incredible adventure, an adventure that started for me many years ago, and a journey that you have supported each step of the way.

To our Lead Flight Director, Gary Horlacher (Houston) and our Lead Payload Operations Director Patricia Patterson (Huntsville) – what an amazing job. Endless hours, minimal sleep, and herding a cast of thousands to establish the priorities that would define success for our Expedition. Thank you for your service, and for your outstanding leadership.

To our incredibly talented team supporting from Mission Control at all of our centers – Houston, Huntsville, Tsukuba, Cologne, and Moscow – you are incredible professionals without which our human spaceflight program could not exist. Thank you for your dedication, service and professionalism.

My life has been driven by dreams and goals. One of my concerns has always been that following my heart to achieve my dreams would have a deep impact on my family and friends. In the Navy, we endured multiple extended deployments onboard aircraft carriers, constant training cycles in locations away from home, and long days and weekends of training and work when we finally had some time at home. 

In the space program, operational requirements demand the same attention and focus. I have moved my family 12 times in 30 years to make myself available for opportunities to serve that I would have otherwise not been afforded. I have always asked myself – is this worth it? I always assumed “yes”, but could not say definitively in the midst of the journey. My journey has brought my family to several new communities where we needed to learn, adjust, adapt and thrive. We are good at it. My family knows what it is like to live on the East Coast, the West Coast, the desert, the Midwest and the South. My family does not consider varying locations or diverse cultures as barriers to their success, but as opportunities to grow and excel. My children are embarking on their own dreams now, with an energy and focus even greater than I had at their age. My family maintains relationships with lifelong friends all over the country, and now the world. My family believes that dreams are attainable, and that the journey towards their dreams is where the value is found. 

I am very lucky that I have lifelong friends that understand what it was that took me away from my childhood home. I am very lucky to have a family that “gets it”. My wife, Raynette, is amazing at being patient, and at making things work amidst unimaginable chaos. I am very proud of my military family for enduring all that they have over the years. Throughout the sacrifice and endurance, they decided to thrive – typical of our country’s incredible military families. My son, Sean Tingle, wrote and produced the song “To Touch the Stars” in honor of our journey that reached another level of success during ISS Expeditions 54 and 55. After hearing this song, I can definitively say, “Yes, it was worth it”.

To my family, friends and colleagues – THANK YOU for a LIFETIME OF INSPIRATION!

Now, it’s time to get busy again – chop chop hubba bubba!

Astronaut Journal Entry – The Last Week

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry, written in space, by NASA astronaut Scott Tingle.

I can’t believe that Expedition 55 is already over. Today is Sunday, and we will depart the International Space Station (ISS) next Sunday morning (June 3). 

168 days in space. 

There have been many challenging moments, but even more positive highlights of our time on ISS. The new crew from the Soyuz MS-08 spacecraft (Oleg Artymyev, Drew Feustel and Ricky Arnold) joined Norishige Kanai (Nemo), Anton Shkaplerov and I last March. Since then, we have completed two spacewalks, captured and released the SpaceX Dragon-14 cargo craft, captured the Cygnus OA-9 cargo craft and completed a myriad of maintenance and science activities. 

The team on the ground controlling, monitoring, supporting and planning has been amazing. It is always great to work with them, and especially during the moments where the equipment, tools, procedures or crew need help. It is incredible to see how much a good team can accomplish when methodically placing one foot in front of the other. 

I have been lucky in that the first crew (Mark Vande Hei, Joe Acaba and Alexander Misurkin (Sasha)) and the second crew (Drew, Ricky and Oleg) were all amazing to work with. I do believe the planets aligned for my mission onboard ISS. 

Drew and Ricky have been friends forever, and listening to them nip at each other provided a ton of great humor for the ground and for us. Their one-liners to each other reminded me of several scenes from the movie Space Cowboys. 

This a great example that happened as I was writing this log entry:    

Ricky:  Hey Maker, is this your smoothie?   

Maker:  No.  

Ricky:  It must be Drew’s.

 Drew:  Hey Ricky, don’t drink my smoothie.

Ricky:  What smoothie? This one has my name on it (as he writes his name on it).

 Drew:  Okay, Grandpa Underpants, hands off my smoothie.

Ricky:  Okay, Feustelnaut – we have rules around here, so this is my smoothie now!

All:  Much laughing. (To quote my kids: “LOL!”)

One the hardest things to do in space is to maintain positive control of individual items such as tools, spare parts, fasteners, etc. We try very hard not to lose things, but even with all of the attention and positive control, items can still float away and disappear. 

We generally hold items in a crew transfer bag (CTB). Inside the CTB are many items for the system that it supports. When the CTB is opened, the items are free floating inside the bag and tend to escape. It is very difficult to maintain control of the items – especially if they are small, do not have Velcro, or when the daily schedule is so tight that we are rushing to stay on time. We always try to close the CTB’s and Ziploc bags after removing or replacing each item to maintain positive control, but this takes much more time to do for individual items, and if the timeline is tight, we absorb more risk by rushing. 

The same applies for tools, which we usually keep in a Ziploc bag while working on individual systems and tasks. Last month, I was installing a new low temperature cooling loop pump that had failed a month or two earlier. I gathered the needed tools into my modified (with Velcro) Ziploc bag as I always do and floated over to the work area. When I got there, one of the tools that I had gathered was missing. I looked for 30 minutes, and could not find it. Lost items are very hard to find because the items that escape are usually barely moving and blend in with the environment very quickly. A lost item could be right in front of us and we would never see it. 

Our crew, after learning these lessons, decided that when anyone loses something, we would tell the other crew members what we had lost with a general location. This has had a huge impact on finding items. If a different crew member can help within the first minutes of losing an item, the new crew member has an excellent chance of finding the item. We have proven this technique several times during the expedition – and Nemo was the very best at quickly finding lost items. But, in my case, we still could not find the missing tool. Our amazing ground team understood and vectored me to a replacement tool and I finished the job. I spent the next 3 weeks watching, looking and never forgetting about the lost tool. Then, one day last week, Oleg came to the lab and handed us a tool he had found in his Soyuz spacecraft, way on the aft side of the ISS. Amazing. We finally found the tool and I was happy again. This was a lucky ending. ISS has many corners, crevices and hard-to-see areas where missing items could hide and never be found.

We captured a Cygnus cargo craft last Thursday. I was very impressed with the entire team. Our specialists and training professionals in Mission Control did a great job preparing the necessary procedures and making sure we were proficient and ready to conduct operations. The robotic arm is a wonderful system that we could not operate ISS without. Being in space, however, it has some very unique handling qualities. If you think about a spring-mass-damper system just as you did during physics or control theory class, and then remove the damper, you will see a system that is very subject to slow rate oscillations. 

In test pilot terms, damping ratio is very low and the latency is well over a half of a second. Also in test pilot terms – this is a pilot-induced oscillations (PIO) generator. These characteristics require crew to “fly” the robotic arm using open-loop techniques, which requires a huge amount of patience. Test pilots are sometimes not very patient, but understanding the system and practicing with the incredible simulators that our ground team built and maintain help keep our proficiency as high as possible. The capture went flawlessly, and I was very impressed with the professionalism across the board – crew, flight controllers and training professionals – what a great job!

Drew, Ricky and I got to play guitar a few times while on ISS. This was fun! Drew connected pickups to the acoustic guitars and then connected the pickups to our tablets for amplification. I’ve never heard an acoustic guitar sound like an electric guitar amped up for heavy metal before. We had a great jam on the song “Gloria”, and a couple others. Rock on!

Last night we had our last movie night. The entire crew gathered in Node 2 and watched Avengers Infinity Wars on the big screen. We enjoy each other’s company, as we did during Expedition 54, and this was a welcome break from the daily grind of trying to complete the required stowage, maintenance and science activities while preparing for departure.

Our last full weekend here on ISS. I gave myself a haircut. We usually clean our spaces each weekend to make sure we can maintain a decent level of organization, efficiency and morale. This weekend is no different, and it is time for me to vacuum out all of our filters and vents. You’d be amazed at what we find!

The top 5 things I will miss when I am no longer in space:

  1. The incredible team that supports ISS operations from our control centers
  2. The camaraderie onboard ISS
  3. The breathtaking view of the Earth, Moon, Sun and Stars
  4. Floating/flying from location to location with very little effort
  5. Operations in the extreme environment of space

Astronaut Journal Entry – Week 12

Wow, time has gone by extremely fast. The mid-deployment phase will be short-lived for me this time, as the new crew (Drew Feustel, Ricky Arnold, and Oleg Artemyev) will arrive on March 23rd, and then we have at least one spacewalk on the 29th, followed by a planned SpaceX Dragon cargo craft arrival on the 4th of April. It’s a little strange being up here with only two other crewmates. We are still very busy, but the overall work effort is half of what it was just a week ago. My crewmate, Nemo (Norishige Kanai), and I are trying to use the time to prepare for the upcoming very busy schedule, and we have been having some great success getting a ton of details taken care of.  

image

Yesterday I had a funny event, though. I was controlling a robot named “Justin” who was located in Munich. The research and demonstration events were so interesting and fun that I offered them my lunch hour to do an additional protocol and have a longer debrief session. The ground team responded happily and accepted the offer – any extra time with crew onboard the International Space Station (ISS) is valuable to our programs. Halfway through the event, the team needed a few minutes to shut down and restart the robot, and I surmised that since I was skipping my break, this would be a good time to use the toilet. And I did, use the toilet. And literally 3 minutes later I returned, waited another 2 minutes for the robot systems to connect, and we began another great session controlling Justin from ISS with no loss to science. 

Later that same day, I was approached by the ground team in Houston (not the test team I was working with in Munich) and queried if something was wrong, and why did I have to take a toilet break while we were executing valuable science? They were concerned that I might have a medical issue, as taking a break in the middle of some very valuable science is not normal for us to do while on ISS. It’s nice to know that we have literally hundreds of highly-trained professionals looking out for us.

While flying fast-moving jets, we practice the art of recovering from unusual attitudes. We close our eyes, and let the instructor put the jet in an unexpected attitude. Sometimes straight up, sometimes straight down, sometimes upside down, and sometimes anything in-between. The goal is to open our eyes, analyze the situation and make rapid and smooth corrections to power and attitude to effect a speedy recovery to straight and level flight without departing controlled flight, or having to endure high G’s, or experiencing big losses of altitude. 

image

Sometimes, when I crawl into my crew quarters on the space station, it is very dark – just like closing our eyes in the jet. And then, as I sleep, my body floats around and changes position. When I awake in total darkness, I have to figure out what attitude I am in relative to my crew quarters and then right myself.  “Unusual Attitude Recovery” can be pretty funny. And sometimes, my heart can get pumping as I awake and realize I don’t know what my attitude is. I execute my procedures to figure out what my attitude is, and then correct it. At first, it used to take me a while to realize. But now, it is second nature – and it always brings a smile to my face.

Science Launching to Station Looks Forward and…

Some of the earliest human explorers used mechanical tools called sextants to navigate vast oceans and discover new lands. Today, high-tech tools navigate microscopic DNA to discover previously unidentified organisms. Scientists aboard the International Space Station soon will have both types of tools at their disposal.

image

Orbital ATK’s Cygnus spacecraft is scheduled to launch its ninth contracted cargo resupply mission to the space station no earlier than May 21. Sending crucial science, supplies and cargo to the crew of six humans living and working on the orbiting laboratory.

Our Gemini missions conducted the first sextant sightings from a spacecraft, and designers built a sextant into Apollo vehicles as a lost-communications navigation backup. The Sextant Navigation investigation tests use of a hand-held sextant for emergency navigation on missions in deep space as humans begin to travel farther from Earth.

image

Jim Lovell (far left) demonstrated on Apollo 8 that sextant navigation could return a space vehicle home.

The remoteness and constrained resources of living in space require simple but effective processes and procedures to monitor the presence of microbial life, some of which might be harmful. Biomolecule Extraction and Sequencing Technology (BEST) advances the use of sequencing processes to identify microbes aboard the space station that current methods cannot detect and to assess mutations in the microbial genome that may be due to spaceflight.  

image

Genes in Space 3 performed in-flight identification of bacteria on the station for the first time. BEST takes that one step farther, identifying unknown microbial organisms using a process that sequences directly from a sample with minimal preparation, rather than with the traditional technique that requires growing a culture from the sample.

image

Adding these new processes to the proven technology opens new avenues for inflight research, such as how microorganisms on the station change or adapt to spaceflight.

The investigation’s sequencing components provide important information on the station’s microbial occupants, including which organisms are present and how they respond to the spaceflight environment – insight that could help protect humans during future space exploration. Knowledge gained from BEST could also provide new ways to monitor the presence of microbes in remote locations on Earth.

Moving on to science at a scale even smaller than a microbe, the new Cold Atom Lab (CAL) facility could help answer some big questions in modern physics.

image

CAL creates a temperature ten billion (Yup. BILLION) times colder than the vacuum of space, then uses lasers and magnetic forces to slow down atoms until they are almost motionless. CAL makes it possible to observe these ultra-cold atoms for much longer in the microgravity environment on the space station than would be possible on the ground.

image

Results of this research could potentially lead to a number of improved technologies, including sensors, quantum computers and atomic clocks used in spacecraft navigation.

A partnership between the European Space Agency (ESA) and Space Application Services (SpaceAps), The International Commercial Experiment, or ICE Cubes Service, uses a sliding framework permanently installed on the space station and “plug-and-play” Experiment Cubes.

image

The Experiment Cubes are easy to install and remove, come in different sizes and can be built with commercial off-the-shelf components, significantly reducing the cost and time to develop experiments.

ICE Cubes removes barriers that limit access to space, providing more people access to flight opportunities. Potential fields of research range from pharmaceutical development to experiments on stem cells, radiation, and microbiology, fluid sciences, and more.

CubeSat Facebook Live

The International Space Station is often used to deploy small satellites, a low-cost way to test technology and science techniques in space. On board this time, for deployment later this summer, are three CubeSats that will help us monitor rain and snow, study weather and detect and filter radio frequency interference (RFI). 

Join us on Facebook Live on Saturday, May 19 at 3:30 p.m. EDT on the NASA’s Wallops Flight Facility page to hear from experts and ask them your questions about these small satellites.
