5 Out Of This World Experiments Awaiting Crew-1 Space Scientists

Crazy Facts About the #YearInSpace

Astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko returned from their One-Year Mission on March 1. When you spend a year doing anything, you’re bound to accumulate some crazy stats. Here are a few:

During their year in space, Kelly and Kornienko traveled over 143 million miles, conducting research to prepare us for our journey to Mars, which will be about 140,000,000 miles from Earth.

The International Space Station travels at a speed of 5 miles per second and orbits the Earth every 90 minutes.

These visiting vehicles brought food, supplies, experiments and more crew members to the space station.

Since the space station is orbiting the Earth at 17,500 miles per hour, the crew onboard sees 16 sunrises and sunsets each day.

Water is a precious and limited resource in space, so crew members recycle it whenever possible. That includes recycling their own urine.

Blooms in the Baltic

Every summer, phytoplankton – microscopic plant-like organisms – spread across the North Atlantic, with blooms spanning hundreds and sometimes thousands of miles. Nutrient-rich, cooler waters tend to promote more growth among marine plants and phytoplankton than is found in tropical waters. Blooms this summer off Scandinavia seem to be particularly intense.

On July 18, 2018, the Operational Land Imager (OLI) on Landsat 8 acquired a natural-color image of a swirling green phytoplankton bloom in the Gulf of Finland, a section of the Baltic Sea. Note how the phytoplankton trace the edges of a vortex; it is possible that this ocean eddy is pumping up nutrients from the depths.

Though it is impossible to know the phytoplankton type without sampling the water, three decades of satellite observations suggest that these green blooms are likely to be cyanobacteria (blue-green algae), an ancient type of marine bacteria that capture and store solar energy through photosynthesis (like plants).

In recent years, the proliferation of algae blooms in the Baltic Sea has led to the regular appearance of “dead zones” in the basin. Phytoplankton and cyanobacteria consume the abundant nutrients in the Baltic ¬and deplete the oxygen. According to researchers from Finland’s University of Turku, the dead zone this year is estimated to span about 70,000 square kilometers (27,000 square miles).

Vote While You float: An Astronaut Voting Story

With the excitement of getting to the polls on Election Day many people will have a hard time keeping their feet on the ground, but astronauts who vote literally have to strap themselves down so they don’t float away.

Astronauts orbit the Earth at 17,000 miles per hour, but thanks to a bill passed by Texas legislatures in 1997 that put in place technical voting procedure for astronauts – nearly all of whom live in Texas – they also have the ability to vote from space!

Image Kjell Lindgren released on social media of the US flag floating in the Cupola module (11/12/2015) 

For astronauts, the voting process starts a year before launch, when astronauts are able to select which elections (local/state/federal) that they want to participate in while in space. Then, six months before the election, astronauts are provided with a standard form: the “Voter Registration and Absentee Ballot Request – Federal Post Card Application.”

 ‘Space voting’ was first used the same year it was implemented in 1997. NASA astronaut David Wolf became the first American to vote in space while on the Russian Mir Space Station.

While astronauts don’t have to wait in line for his ballot like the rest of us, there is one disadvantage to voting in space: they miss out on the highly coveted “I Voted” sticker.

NASA Spotlight: Christina Hernandez, NASA Mars 2020 Rover Instrument Engineer

“I was in love with the beauty of space. It was my introduction to appreciating the beauty of complex, chaotic things—black holes, giant gas planets, or killer asteroids—that got my imagination riled up.“ -Christina Hernandez

Christina Hernandez, a space enthusiast and self-proclaimed nerd, is an aerospace engineer at our Jet Propulsion Laboratory in California where she works as an instrument engineer on our newest rover mission – Mars2020. The Mars2020 rover is a robotic scientist that is launching to the Red Planet next year. If you would like to launch to the Red Planet as well, you can Send Your Name to Mars along with millions of other people! Christina’s job is to make sure that the instruments we send to the Martian surface are designed, built, tested and operated correctly so we can retrieve allll the science. When she isn’t building space robots, she loves exploring new hiking trails, reading science fiction and experimenting in the kitchen. Christina took a break from building our next Martian scientist to answer some questions about her life and her career: 

If you could go to Mars, would you? And what are three things you’d bring with you?

Only if I had a round trip ticket! I like the tacos and beach here on Earth too much. If I could go, I would bring a bag of Hot Cheetos, a Metallica album, and the book On the Shoulders of Giants.

If you could name the Mars2020 rover, what would you name it and why?

Pilas, a reference to a phrase my family says a lot, ponte las pilas. It literally means put your batteries on or in other words, get to work, look alive or put some energy into it. Our rover is going to need to have her batteries up and running for all the science she is going to be doing! Luckily, the rover has a radioisotope thermoelectric generator (RTG) to help keep the batteries charged!

What’s been your most memorable day at NASA?

It’s been seeing three of the instruments I worked on getting bolted and connected to the flight rover. I’ll never forget seeing the first 1’s and 0’s being exchanged between the rover compute element (RCE), the rover’s on-board brain, and the instruments’ electronics boxes (their brains). I am sure it was a wonderful conversation between the two!

It’s a long journey to get from Earth to Mars. What would be on your ultimate road trip playlist?

Metallica, The Cure, Queen, Echo and the Bunnymen, Frank Sinatra, Ramon Ayala, AC/DC, Selena, Los Angeles Azules, ughhhh – I think I just need a Spotify subscription to Mars.

What is one piece of advice you wish someone would’ve told you?

Take your ego out of the solution space when problem solving.

Do you have any secret skills, talents, or hobbies?

I love reading. Each year I read a minimum of 20 books, with my goal this year being 30 books. It’s funny I increased my goal during what has definitely been my busiest year at work. I recently got into watercolor painting. After spending so much time connected at work, I started looking for more analog hobbies. I am a terrible painter right now, but I painted my first painting the other day. It was of two nebulas! It’s not too bad! I am hoping watercolor can help connect me more to the color complexities of nature...and it’s fun!

What’s a project or problem that you would love the ability to tackle/work on?

I would love to work on designs for planetary human explorers. So far, I have focused on robotic explore, but when you throw a “loveable, warm, squishy thing” into the loop, its creates a different dimension to design – both with respect to operability and risk.

Thanks so much Christina! The Mars2020 rover is planned to launch on July 17, 2020, and touch down in Jezero crater on Mars on February 18, 2021.

Solar System: Things to Know This Week

See history in the making on September 22! That's the day OSIRIS-REx, the first U.S. mission to carry samples from an asteroid back to Earth, will make a close approach to Earth as it uses our planet's gravity to slingshot itself toward the asteroid Bennu. 

Over the course of several days, observatories and amateur astronomers will be able to spot the spacecraft. Below, 10 things to know about this incredible mission that will bring us the largest sample returned from space since the Apollo era.

1. Big Deal

OSIRIS-REx seeks answers to the questions that are central to the human experience: Where did we come from? What is our destiny? Asteroids, the leftover debris from the solar system formation process, can help us answer these questions and teach us about the history of the Sun and planets.

2. That's a Long Acronym

Yup. OSIRIS-REx stands for the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer spacecraft. The gist: It will rendezvous with, study, and return a sample of the asteroid Bennu to Earth.

3. Lots of Instruments, Too

While all the acronyms for each instrument may be alphabet soup, each has a job/role to perform in order to complete the mission. Explore what each one will do in this interactive webpage. 

4. Nice to Meet You, Bennu

Scientists chose Bennu as the mission target because of its composition, size, and proximity to Earth. Bennu is a rare B-type asteroid (primitive and carbon-rich), which is expected to have organic compounds and water-bearing minerals like clays.

5. Hard Knock Life

Bennu had a tough life in a rough neighborhood: the early solar system. It's an asteroid the size of a small mountain born from the rubble of a violent collision, hurled through space for millions of years and dismembered by the gravity of planets—but that's exactly what makes it a fascinating destination.

6. High Fives All Around

In 2018, OSIRIS-REx will approach Bennu and begin an intricate dance with the asteroid, mapping and studying Bennu in preparation for sample collection. In July 2020, the spacecraft will perform a daring maneuver in which its 11-foot arm will reach out for a five-second "high-five" to stir up surface material, collecting at least 2 ounces (60 grams) of small rocks and dust into a sample return capsule.

7. Home Sweet Home

OSIRIS-REx launched on September 8, 2016 from Cape Canaveral, Florida on an Atlas V rocket. In March 2021, the window for departure from the asteroid will open and OSIRIS-REx will begin its return journey to Earth, arriving two-and-a-half years later in September 2023.

8. Precious Cargo

The sample will head to Earth inside of a return capsule with a heat shield and parachutes that will separate from the spacecraft once it enters the Earth's atmosphere. The capsule containing the sample will be collected at the Utah Test and Training Range. Once it arrives, it will be transported to NASA's Johnson Space Center in Houston for examination. For two years after the sample return (from late 2023-2025) the science team will catalog the sample and conduct the analysis needed to meet the mission science goals. NASA will preserve at least 75% of the sample at NASA's Johnson Space Flight Center in Houston for further research by scientists worldwide, including future generations of scientists.

9. Knowledge Is Power

Analyzing the sample will help scientists understand the early solar system, as well as the hazards and resources of near-Earth space. Asteroids are remnants of the building blocks that formed the planets and enabled life. Those like Bennu contain natural resources such as water, organics and metals. Future space exploration and economic development may rely on asteroids for these materials.

10. Hitch a Ride

Journey with OSIRIS-REx as it launches, cruises, and arrives to Bennu in this interactive timeline.

Setting Sail to Travel Through Space: 5 Things to Know about our New Mission

Our Advanced Composite Solar Sail System will launch aboard Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand no earlier than April 23, at 6 p.m. EDT. This mission will demonstrate the use of innovative materials and structures to deploy a next-generation solar sail from a CubeSat in low Earth orbit.

Here are five things to know about this upcoming mission:

1. Sailing on Sunshine

Solar sails use the pressure of sunlight for propulsion much like sailboats harness the wind, eliminating the need for rocket fuel after the spacecraft has launched. If all goes according to plan, this technology demonstration will help us test how the solar sail shape and design work in different orbits.

2. Small Package, Big Impact

The Advanced Composite Solar Sail System spacecraft is a CubeSat the size of a microwave, but when the package inside is fully unfurled, it will measure about 860 square feet (80 square meters) which is about the size of six parking spots. Once fully deployed, it will be the biggest, functional solar sail system – capable of controlled propulsion maneuvers – to be tested in space.

3. Second NASA Solar Sail in Space

If successful, the Advanced Composite Solar Sail System will be  the second NASA solar sail to deploy in space, and not only will it be much larger, but this system will also test navigation capabilities to change the spacecraft’s orbit. This will help us gather data for future missions with even larger sails.

4. BOOM: Stronger, Lighter Booms

Just like a sailboat mast supports its cloth sails, a solar sail has support beams called booms that provide structure. The Advanced Composite Solar Sail System mission’s primary objective is to deploy a new type of boom. These booms are made from flexible polymer and carbon fiber materials that are stiffer and 75% lighter than previous boom designs. They can also be flattened and rolled like a tape measure. Two booms spanning the diagonal of the square (23 feet or about 7 meters in length) could be rolled up and fit into the palm of your hand!

5. It’s a bird...it’s a plane...it’s our solar sail!

About one to two months after launch, the Advanced Composite Solar Sail System spacecraft will deploy its booms and unfurl its solar sail. Because of its large size and reflective material, the spacecraft may be visible from Earth with the naked eye if the lighting conditions and orientation are just right!

NASA and Veterans

November 11 each year is a day we honor those who have served in our nation’s armed forces. 

Discover how we have close ties to the military, even to this day, and see who has traded in their camouflage uniform for an astronaut flight suit.

There have been veterans working for us since the beginning, even when it was still called the National Advisory Committee for Aeronautics (NACA). 

Additionally, there are several active duty military members working at NASA facilities through special government programs.

Today, there are more than 1500 veterans currently employed with us. Their experiences in the military make their expertise invaluable around the agency. We value the unique leadership style they bring to the work place.  Above and below are some astronaut veterans.

A Partnership for the Space Age

Since the early days of NASA, we’ve partnered with all branches of the military. We still work closely with the military today and rely on the expertise of our service members to support our missions both while in active duty and in the civilian workforce. Here are some examples of this close partnership:

The Marines helped with recovery efforts of Astronaut Alan Shepard at the end of his sub-orbital flight on May 5, 1961...a task performed across several of our missions.

Today, the Navy helps us recover spacecraft, just like the Orion space capsule...which will one day carry astronauts into deep space and eventually on our journey to Mars. 

. . .and the Air Force has traditionally and continues to help us transport sensitive and critical space hardware around the globe. 

The Coast Guard has even helped us access remote locations to collect oceanographic data as part of our efforts to study and learn more about the Earth. 

We’ve partnered with the Army to use their unique capabilities at the Yuma Proving Ground to test the entry, descent and landing of our spacecraft systems.

To all the Veteran’s out there, we thank you for your service to America and your continued support of America’s space program.

Happy Veteran’s Day!

AI, Cancer Therapy and Chemical Gardens Headed to Space Station

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:

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.
