Take A Dive Between Saturn And Its Rings To See What Our Cassini Spacecraft Saw During Its First Daring

The NASA Village

Today in the NASA Village… That’s my Ride: Robots and Rovers.

Future cars could very likely resemble the rovers currently in NASA’s parking lot. The newest rovers have gotten rid of the more traditional ideas and come up with some pretty amazing machinery.  Amy Fritz is a mechanical engineer that works with these rovers.  When I asked Amy how she found herself in such a cool job she said, “My parents were very big influences on my career choices. I can remember when I was a little girl and my dad and I would build Legos together, or we would take the remote apart to see how it worked.  That really inspired me to want to pursue a career in engineering.  I then later developed an affinity for cars so, of course, the only rational thing to do was to go after a degree in mechanical engineering.”

The wheels of this rover move independent of each other, regardless of which direction the vehicle points.  To parallel park one would just pull up to the spot and turn the wheels to scoot in.  I am not sure how much parallel parking is required on other planets, but it could help us move very close to an object for observation out the “front” of the vehicle, while moving laterally.

The bubble in the front of the glass is actually a magnifying glass so astronauts can better see the minerals on other planets without having to leave the rover!

These rovers also allow one to change drivers, without anyone having to change seats!

Here is a video of the Modular Robotic Vehicle (MRV) in action.

Rovers have been used on the surface of the moon in the past. Check out the Apollo 16 rover as astronauts John Young and Charlie Duke take a spin.

The rovers can also be hybrids of rovers and humanoid robots.  For instance, the robot could serve as a scout, providing advanced maps and soil samples, and beginning work on the infrastructure that astronauts would need.  The crew that follows would then be much more prepared for the exploration ahead.  Amy describes her working life as very…interesting.  “One minute you’re working on a design, sitting at your desk and the next minute you’re being called into the high bay to replace a suspension arm on one of the rovers.”

The first Robonaut began in 1997.  The goal was to build a humanoid robot that could assist us with tasks where it might be useful to have another pair of hands.  This type of robot could also perform jobs that where it was too dangerous to risk human life or even too time-consuming and mundane.

Robonaut was revealed in 2010 as the most advanced humanoid robot of its time.  It made its way to the International Space Station on-board the space shuttle Discovery. It was the first humanoid-robot in space and it rode on the final shuttle mission.  This technology is still developing today.

Meet the future of Robonaut on station:

This technology could someday service communications, weather and reconnaissance satellites, which have direct benefits on Earth.  The next step for robotic capabilities is to explore near-Earth objects, including asteroids and comets, and eventually Mars. Something Amy mentioned that I found interesting was her greatest hurdle was asking for help.  “I know that might sound silly, but I’m used to always being independent and trying to figure things out for myself.“  This is one of the things I have discovered about myself too.  The kind of drive that Amy has is special, that desire to figure things out for yourself. But, remember, having the humility to ask questions and ask for help can lead you even further!

What You Should Know About Scott Kelly’s #YearInSpace

1. It’s Actually More Like a Three-Year Mission

NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko may have had a year-long stay in space, but the science of their mission will span more than three years. One year before they left Earth, Kelly and Kornienko began participating in a suite of investigations aimed at better understanding how the human body responds to long-duration spaceflight. Samples of their blood, urine, saliva, and more all make up the data set scientists will study. The same kinds of samples continued to be taken throughout their stay in space, and will continue for a year or more once they return.

2. What We Learn is Helping Us Get to Mars

One of the biggest hurdles of getting to Mars is ensuring humans are “go” for a long-duration mission and that crew members will maintain their health and full capabilities for the duration of a Mars mission and after their return to Earth. Scientists have solid data about how bodies respond to living in microgravity for six months, but significant data beyond that timeframe had not been collected…until now. A mission to Mars will likely last about three years, about half the time coming and going to Mars and about half the time on Mars. We need to understand how human systems like vision and bone health are affected by the 12 to 16 months living on a spacecraft in microgravity and what countermeasures can be taken to reduce or mitigate risks to crew members during the flight to and from Mars. Understanding the challenges facing humans is just one of the ways research aboard the space station helps our journey to Mars.

3. The Science Will Take Some Time

While scientists will begin analyzing data from Kelly and Kornienko as soon as they return to Earth, it could be anywhere from six months to six years before we see published results from the research. The scientific process takes time, and processing the data from all the investigations tied to the one-year mission will be no easy task. Additionally, some blood, urine and saliva samples from Kelly and Kornienko will still be stored in the space station freezers until they can be returned on the SpaceX Dragon spacecraft. Early on in the analytical process scientists may see indications of what we can expect, but final results will come long after Kelly and Kornienko land.

4. This Isn’t the First Time Someone Has Spent a Year in Space

This is the first time that extensive research using exciting new techniques like genetic studies has been conducted on very long-duration crew members. Astronaut Scott Kelly is the first American to complete a continuous, year-long mission in space and is now the American who has spent the most cumulative time in space, but it’s not the first time humans have reached this goal. Previously, only four humans have spent a year or more in orbit on a single mission, all aboard the Russian Mir Space Station. They all participated in significant research proving that humans are capable of living and working in space for a year or more.

Russian cosmonaut Valery Polyakov spent 438 days aboard Mir between January 1994 and March 1995 and holds the all-time record for the most continuous days spent in space.

Cosmonaut Sergei Avdeyev spent 380 days on Mir between August 1998 and August 1999.

Cosmonauts Vladimir Titov and Musa Manarov completed a 366-day mission from December 1987 to December 1988.

5. International Collaboration is Key

The International Space Station is just that: international. The one-year mission embodies the spirit of collaboration across countries in the effort to mitigate as many risks as possible for humans on long-duration missions. Data collected on both Kelly and Kornienko will be shared between the United States and Russia, and international partners. These kinds of collaborations help increase more rapidly the biomedical knowledge necessary for human exploration, reduce costs, improve processes and procedures, and improve efficiency on future space station missions.

6. So Much Science!

During Kelly’s year-long mission aboard the orbiting laboratory, his participation in science wasn’t limited to the one-year mission investigations. In all, he worked on close to 400 science studies that help us reach for new heights, reveal the unknown, and benefit all of humanity. His time aboard the station included blood draws, urine collection, saliva samples, computer tests, journaling, caring for two crops in the Veggie plant growth facility, ocular scans, ultrasounds, using the space cup, performing runs with the SPHERES robotic satellites, measuring sound, assisting in configuring cubesats to be deployed, measuring radiation, participating in fluid shifts testing in the Russian CHIBIS pants, logging his sleep and much, much more. All of this was in addition to regular duties of station maintenance, including three spacewalks!

7. No More Food in Pouches

After months of eating food from pouches and cans and drinking through straws, Kelly and Kornienko will be able to celebrate their return to Earth with food of their choice. While aboard the space station, their food intake is closely monitored and designed to provide exactly the nutrients they need. Crew members do have a say in their on-orbit menus but often miss their favorite meals from back home. Once they return, they won’t face the same menu limitations as they did in space. As soon as they land on Earth and exit the space capsule, they are usually given a piece of fruit or a cucumber to eat as they begin their initial health checks. After Kelly makes the long flight home to Houston, he will no doubt greatly savor those first meals.

8. After the Return Comes Reconditioning

You’ve likely heard the phrase, “Use it or lose it.” The same thing can be said for astronauts’ muscles and bones. Muscles and bones can atrophy in microgravity. While in space, astronauts have a hearty exercise regimen to fight these effects, and they continue strength training and reconditioning once they return to Earth. They will also participate in Field Tests immediately after landing. Once they are back at our Johnson Space Center, Functional Task Tests will assess how the human body responds to living in microgravity for such a long time. Understanding how astronauts recover after long-duration spaceflight is a critical piece in planning for missions to deep space.

9. Twins Studies Have Researchers Seeing Double

One of the unique aspects of Kelly’s participation in the one-year mission is that he has an identical twin brother, Mark, who is a former astronaut. The pair have taken part in a suite of studies that use Mark as a human control on the ground during Scott’s year-long stay in space. The Twins Study is comprised of 10 different investigations coordinating together and sharing all data and analysis as one large, integrated research team. The investigations focus on human physiology, behavioral health, microbiology/microbiome and molecular/omics. The Twins Study is multi-faceted national cooperation between investigations at universities, corporations, and government laboratories.

10. This Mission Will Help Determine What Comes Next

The completion of the one-year mission and its studies will help guide the next steps in planning for long-duration deep space missions that will be necessary as humans move farther into the solar system. Kelly and Kornienko’s mission will inform future decisions and planning for other long-duration missions, whether they are aboard the space station, a deep space habitat in lunar orbit, or a mission to Mars.

sorry, i don't know much about earth science (though it sounds very intriguing), but - what exactly is it that you do? does it take a lot of time? is it fun but challenging? was it hard to get your job? have you always wanted to work with earth science?

@mothdog: What is something everyone needs to know about the International Space Station and science in space?

Hello there 👋

Welcome back to Mindful Mondays! 🧘

Mondays are, famously, most people’s seventh favorite day of the week. And Mondays where everything is darker, longer, and colder than normal? Thanks, but no thanks.

But don’t panic; we’ve got something to help. It might be small, but it can make a big difference. Just ten minutes of mindfulness can go a long way, and taking some time out to sit down, slow down, and breathe can help center your thoughts and balance your mood. Sometimes, the best things in life really are free.

This year, we have teamed up with the good folks at @nasa. They want you to tune in and space out to relaxing music and ultra-high-definition visuals of the cosmos—from the surface of Mars.  

Sounds good, right? Well, it gets better. Watch more Space Out episodes on NASA+, a new no-cost, ad-free streaming service.

Why not give it a try? Just a few minutes this Monday morning can make all the difference, and we are bringing mindfulness straight to you.

What Cargo is Launching in October to the International Space Station?

On Monday, Oct. 17, Orbital ATK is scheduled to send new science experiments to the International Space Station. 

The Cygnus spacecraft will blast off from our Wallops Flight Facility in Virginia at 7:40 p.m. EDT carrying more than 5,100 pounds of science, supplies and equipment.

Let’s take a look at a few of these experiments:

Cool Flames

Low-temperature fires with no visible flames are known as cool flames. The Cool flames experiment examines these low-temperature combustion of droplets of a variety of fuels and additives in low gravity.

Why are we studying this? Data from this experiment could help scientists develop more efficient advanced engines and new fuels for use in space and on Earth.

Lighting Effects

Light plays a powerful role in our daily, or circadian, rhythms. Astronauts aboard the space station experience multiple cycles of light and dark every 24 hours, which, along with night shifts and the stresses of spaceflight, can affect their sleep quantity and quality.

The Lighting Effects investigation tests a new lighting system aboard the station designed to enhance crew health and keep their body clocks in proper sync with a more regular working and resting schedule.

Why are we studying this? Lighting manipulation has potential as a safe, non-pharmacological way to optimize sleep and circadian regulation on space missions. People on Earth, especially those who work night shifts, could also improve alertness and sleep by adjusting lighting for intensity and wavelength.

EveryWear

A user-friendly tablet app provides astronauts with a new and faster way to collect a wide variety of personal data. The EveryWear experiment tests use of this French-designed technology to record and transmit data on nutrition, sleep, exercise and medications. Astronauts use the app to complete questionnaires and keep medical and clinical logs. They wear a Smartshirt during exercise that records heart activity and body positions and transmits these data to the app. Finally, rather than manually recording everything that they eat, crew members scan barcodes on food packets to collect real-time nutritional data.

Why are we studying this? EveryWear has the potential for use in science experiments, biomedical support and technology demonstrations.

Fast Neturon Spectrometer

Outside the Earth’s magnetic field, astronauts are exposed to space radiation that can reduce immune response, increase cancer risk and interfere with electronics.

The Fast Neutron Spectrometer (FNS) experiment will help scientists understand high-energy neutrons, part of the radiation exposure experienced by crews during spaceflight, by studying a new technique to measure electrically neutral neutron particles.

Why are we studying this? This improved measurement will help protect crews on future exploration missions, like our journey to Mars.

Do pets like cats and dogs need to have their eyes protected in anyway? Should they be kept away from windows?

They should be fine. Animals typically don’t look at the Sun so they probably won't during the eclipse either.

Dolphins x Astronauts: The collab we didn't know we needed 

A pod of curious dolphins added extra meaning and porpoise to the recovery of Crew-9′s SpaceX Dragon capsule and its four explorers shortly after splashdown. Inside the capsule were astronauts Nick Hague, Suni Williams, Butch Wilmore, and cosmonaut Aleksandr Gorbunov, who splashed down off the coast of Florida at 5:57pm ET (2127 UTC) on March 18, 2025, concluding their scientific mission to the International Space Station. See Crew-9 return from deorbit to splashdown in this video. (The dolphins appear at 1:33:56.)

What design steps do you take to make sure that the robot runs smoothly, without anything like sand getting in the gears and wires?

Is it safe to look at the eclipse if it isn't fully covered by the sun? Say 75%

Not without proper eye wear. There will still be too much light that could burn your eyes. But you can have a ton of fun viewing the Sun using a https://eclipse.aas.org/eye-safety/projection. In fact, there is a sunspot that is now on the Sun that you should be able to see using this indirect method!
