Jeannette Epps was so excited. She just learned she would be a crew member on the space station for Expedition 56/57 beginning in 2018. She fired off a quick email to one of her astronaut friends, Scott Tingle, to let him know. In her excitement, the last two words of her email got mixed up. Where is she going?

Hi Scott,
I’m off to the space station in 2018! I guess it is time to buy winter clothes for training in Dyst Voyu!

The International Space Station is a massive orbiting science laboratory that spans the length of a football field. Countries from around the world submit experiments to be tested on the ISS.

But how did ISS come to be? How was it created? The answer: piece by piece. Like a giant jigsaw puzzle in space, ISS was built over many years with the help of several countries and space agencies.

So, now it’s your turn. Unravel a sequence of clues and hints and misdirects as you learn about specific missions involved in the idea, design, construction and operation of the International Space Station. Start by downloading the zip file, transferring both files to your calculator, and opening “ISSPUZZL” and running it.

Two American members of International Space Station Expedition 40 crew — NASA astronauts Reid Wiseman and Steve Swanson — made a friendly wager with European Space Agency astronaut Alexander Gerst of Germany:

If Team USA beat Germany in the 2014 World Cup soccer tournament, then Reid and Steve would paint the American flag on Alexander's bald head. If Germany won, the Americans would shave their heads.

The Americans lost the bet, but still won accolades from soccer fans around the world with their series of spectacular photographs of the cup venues.

Decipher this message they posted when asked if they were outside the space station when they took the photos:

Orbital debris is all of the non-functional parts and pieces from past space missions and collisions that have occurred over the many decades of space exploration from many countries. It includes about 20,000 objects that are larger than a softball, and about half a million objects smaller than a softball. Fortunately all of these objects can be tracked at all times. Because of the relative velocities between the ISS and some of this debris, it is possible that an object could hit the ISS and cause a loss of pressure and life support systems. There are procedures that are followed if such an event is predicted. The first approach is to avoid the collision by changing the relative location of ISS using the Russian thrusters. It takes about 30 hours to coordinate such a move, called a Debris Avoidance Maneuver. The protocol requires a safe zone around the ISS of 30 miles wide by 30 miles long by 1 mile high. It is affectionately known as the “Pizza Box.” If the probability of collision is greater than 1 in 10,000, a maneuver will be conducted unless it will result in additional risk to the crew. If that isn’t possible, the residents onboard ISS are instructed to move to the Russian Soyuz spacecraft in case a collision harms the ISS. This way, the astronauts can be returned safely to Earth if things go wrong.

Your challenge is to run a program called, “PIZZABOX” and determine what course of action is required.

To succeed on missions deep into space, astronauts will need to grow their own food. These autonomous gardens will be essential for the survival of the crew as they travel through the solar system and beyond. When asked what foods from Earth he missed while up on the International Space Station, Shane Kimbrough said, “I miss eating crunchy things. We only have one crunchy thing to eat up here and that is ….” He paused because he realized his crewmates might overhear him. He didn’t want the delicious food to be all gone by the time he got back to the service module. He decided to write a coded message to the students to answer their question.

The Voyager 1 and Voyager 2 space probes were launched in 1977. Astronomers and NASA scientists, at the time, were learning much about the physical laws that govern the universe. The Voyagers were meant to explore our solar system and beyond, as well as serve as Earth’s ambassadors in the event of an encounter with intelligent civilizations.

Today, Voyager 1 is in the Interstellar Medium (ISM), an area that exists beyond our solar system – the space between stars. The Voyager spacecrafts have been reporting data back for the last 40 years.

Located on the surface of each Voyager probe are golden records with information about Earth. These records include sounds and images, as well as symbols that explain how to operate them if they make their way to an intelligent civilization.

NASA’s Juno's mission is to gauge the composition in Jupiter’s atmosphere. The presence of water and other gasses can provide scientists with clues about the origin and formation of the planet. Readings on magnetic and gravity fields can generate a better image of the deep structure of the planet's core.

Juno’s first orbit around Jupiter to collect data was a success. On the second, however, two problems occurred. First, Juno’s data collection instruments went into safe mode and did not record any new information. In addition, an engine-related issue caused flight controllers at the Jet Propulsion Laboratory to delay a key orbital maneuver.

African-American women faced adversity when pursuing STEM careers in the 1950s and 1960s. Nonetheless, many were successful computational experts who aided NASA on its journey to the moon.

Katherine Johnson's calculations were integral in enabling John Glenn to become the first American to orbit Earth aboard Friendship 7 in February 1962. Her work, along with that of many other women like her, set the groundwork for NASA's exploration of space.

Along with T.H. Skopinski, Katherine used sample calculations to determine the precise velocity in which a spacecraft might travel at the conclusion of powered flight. According to the report, what was that velocity in ft/sec?

The Jet Propulsion Laboratory (JPL) in Pasadena, California, monitors the position of the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft and other probes and objects orbiting Mars. MAVEN has an orbit that crosses paths with several of those probes and one of Mars’ two known moons, Phobos, many times in a year.

On July 20, 1976, Viking 1 landed in the Martian plain of Chryse Planitia at 11:56:06 UT, becoming the first American spacecraft to successfully land on the surface of another planet.

Mars has 38% the gravity of Earth. The Viking 1 lander has 572 kg of mass and weighs 5611 N on Earth. Using your calculator, determine the weight (in Newtons) of the Viking lander on Mars. Round to the nearest whole number.

Hint - Weight (in Newtons) is calculated by multiplying the mass of an object (kg) by the gravity of the planet (m/s²). The gravity of Mars is 3.7 m/s². Newtons = kg*m/s²

It’s 2045 and the crew is fast asleep in the Martian habitat at the Gale Crater …

Beep, Beep, Beep ... Beeeeeeep, Beeeeeeep, Beeeeeeep ... Beep, Beep, Beep.

You wake up, groggily, to determine the source of the beeping. It’s not the computer; it’s the Martian air quality sensor, but the readings are normal.

Beeeeeeep, Beep, Beeeeeeep, Beep … Beeeeeeep, Beeeeeeep, Beeeeeeep ... Beeeeeeep, Beeeeeeep ... Beep, Beep, Beep

Beeeeeeep, Beep, Beep ... Beeeeeeep, Beeeeeeep, Beeeeeeep ... Beep, Beeeeeeep, Beeeeeeep ... Beeeeeeep, Beep

You and your crew have been living in the Mars habitat for about a year. This is the first time for an apparent equipment failure. The first rule in fixing electronics is to reboot. You turn the sensor off and back on; readings normal. Back to bed.

Beeeeeeep, Beep ... Beep ... Beep ... Beeeeeeep, Beep, Beep

Beep, Beeeeeeep, Beep, Beep ... Beep, Beeeeeeep ... Beeeeeeep ... Beep, Beeeeeeep, Beep, Beep ... Beeeeeeep, Beeeeeeep, Beeeeeeep ... Beeeeeeep, Beep ... Beeeeeeep, Beeeeeeep, Beep

Beep, Beeeeeeep, Beep ... Beep, Beeeeeeep, Beeeeeeep, Beep ... Beep, Beeeeeeep, Beep, Beep ... Beeeeeeep, Beep, Beeeeeeep, Beeeeeeep

Beep, Beeeeeeep, Beeeeeeep

Beeeeeeep, Beeeeeeep, Beeeeeeep ... Beeeeeeep, Beep

Beeeeeeep, Beeeeeeep, Beeeeeeep ... Beep, Beep, Beeeeeeep, Beep ... Beep, Beep, Beeeeeeep, Beep

The rest of the crew is now awake and staring at the air quality sensor. One of them sits at the computer to play back the 24-hour video of the habitat to listen to the beeps again. She then starts to write something down. Suddenly, she stands up and proclaims, “They’re in trouble!”

Something must be wrong with the communication and navigational systems aboard an incoming resupply ship. It’s carrying all of the food, water, medical supplies, and electronics to keep the habitat up and running, as well as a new crew. They are using the ship’s remote air quality reader to trick the monitor at the habitat to sound alarms with short and long beeps.

Your task is to decipher the message and respond accordingly; it is critical that the resupply vessel land at the exact landing site.

The Vegetable Production System (VEGGIE) is a NASA project that studies the most efficient ways to grow plants in microgravity environments such as the International Space Station. A trip to Mars will certainly require food to be grown while astronauts make the months-long journey to the red planet and back. VEGGIE will help us learn how to achieve this.

Now it’s your turn.

Other components include an analog pump to water the plants, and soil moisture, temperature and light sensors.

The pump (ANALOG.OUT1) is plugged into the TI-Innovator™ Hub’s OUT(put) 1 port. The light sensor is plugged into IN(put) 3 port. Soil moisture is connected to IN(put) 1 port, while the DHT (humidity and temperature) is plugged into IN(put) 2. When they run the project, the pump is supposed to come on when the light level goes below 25 percent. It’s not working, though.

Your challenge: Find out what’s wrong and enter the exact number of the line of code to fix so that the pump runs properly.

Getting a crew to Mars, and safely back to Earth, is a lot harder than many realize.

Astronaut Stan Love, loves to talk about this topic.

How many months would it take to successfully get a crew to Mars, work on Mars, and return safely back to Earth?

You have about five hours of work to do outside of your Martian habitat. First, though, you need to fill your air tanks to ensure you have enough air to breathe while you are working. Your rate of air consumption is 250 mL/min.

Calculate how many liters of air you will need to put in your tanks to complete your task.

Hint - You have the time you will need to wear the air tanks and the consumption rate (per minute).

NASA's initiative New Aviation Horizons (NAH) is an ambitious 10-year plan to build five mostly large-scale experimental aircraft – X-planes – to flight-test new technologies, systems and novel aircraft and engine configurations. Advancing these technologies will enhance the aviation industry at large by helping aircraft become quieter, cleaner and faster.

One of the designs is the X-57 Maxwell, shown here. It has 14 propellers distributed across its wings. At NASA's Armstrong Flight Research Center, engineers have developed a simulator that provides a virtual flight experience according to what the X-plane will actually feel like when it flies, which will be as early as 2018. The simulator enables pilots and engineers to familiarize themselves with the system, reduce reaction times, become proficient at maneuvering the aircraft, and develop emergency procedures.

X-57 principal investigator, Sean Clarke, was running flight tests from the simulator pilot’s seat and kept getting an identical problem on landing. The research team calculated that the average response time by the pilot to resolve the issue was 14.6 seconds. The simulator software seemed to have encoded the issue on the heads-up-display (HUD). See if you can determine what the simulator was indicating was wrong with the plane.

NASA contractor Sierra Nevada Corp. (SNC) has delivered its Dream Chaser spacecraft to the Armstrong Flight Research Center at Edwards Air Force Base, where it will undergo several months of flight-testing.

The test series is part of a developmental space act agreement SNC has with NASA’s Commercial Crew Program. Other contractors include SpaceX, with its Dragon vehicle set to launch atop the Falcon 9 rocket, and Boeing, whose CST-100 Starliner will be launched by an Atlas 5 rocket to rendezvous with the International Space Station.

Sierra Nevada Corp.'s upcoming test campaign will help validate the aerodynamic properties, flight software and control system performance of the Dream Chaser.

The Dream Chaser is also being prepared to deliver cargo to the International Space Station under NASA’s Commercial Resupply Services 2 (CRS2) contract beginning in 2019. The data that SNC gathers from this test campaign will help influence and inform the final design of the cargo Dream Chaser, which will fly at least six cargo delivery missions to and from the space station by 2024.

The Vegetable Production System (Veggie) is a new NASA technology that serves as a deployable plant growth unit capable of producing salad-type crops. It is a safe source of palatable, nutritious fresh food and a tool to support relaxation and recreation. Veggie provides lighting and nutrient delivery, but utilizes the cabin environment for temperature control and as a source of carbon dioxide to promote growth. There are many difficult challenges to developing an apparatus that can successfully grow plants in space, but current research will help future Mars explorers create self-sustaining plant habitats.

One day during International Space Station Expedition 40, NASA astronaut Steve Swanson had trouble setting up the Veggie experiment. He felt like he was missing an important piece. He couldn’t find his NASA handbook on Veggie but did locate this handwritten note from his cosmonaut crewmate, Alexander Skvortsov:

Human life in space depends on the proper storage and management of liquids. The vehicles we use in space, including the International Space Station (ISS), rely on liquids for functions such as energy and propulsion, operations and life-support for the astronauts. The appropriate pressure and temperature for storage is essential to prevent loss of fluids or worse: the failure of a storage tank.

In the microgravity of low earth orbit, rocket fuels and other liquids are stored at cryogenic temperatures. As they warm, they evaporate, which increases the pressure inside of the storage tanks. On Earth, releasing pressure is as simple as having a relief valve that opens when the pressure gets too high, but that involves losing liquids. Astronauts on ISS are experimenting with new techniques to relieve tank pressure without losing any of the precious liquids.
