Science in Space

Driving distances on Mars and the moon! This chart provides a comparison of the distances driven by various wheeled vehicles on the surface of Mars and Earth's moon. Opportunity takes the lead!

"Veggie" Will Expand Fresh Food Production on Space Station. On June 10, 2014, Astronaut Steve Swanson harvested a crop of six red romaine lettuce plants that were grown from seed inside the space station’s Veggie facility, a low-cost plant growth chamber that uses a flat-panel light bank for plant growth and crew observation. For the Veg-01 experiment, researchers are testing and validating the Veggie hardware, and the plants will be returned to Earth to determine food safety.

Replacing ignitors and fuel reservoirs for studies of combustion science in microgravity. KN from space.

NASA astronaut Karen Nyberg preparing another colloidal fluid experiment aboard the International Space Station. This one examines colloidals classified as smart materials, transitioning to a solid-like state in the presence of a magnetic field. New manufacturing models based on these nanoparticles acting as self-assembling building blocks could improve or help develop brake systems, seat suspensions, stress transducers, robotics, rovers, airplane landing gears and vibration damping systems.

Karen Nyberg, Expedition 36 flight engineer, works with new test samples for the Advanced Colloids Experiment, or ACE, housed inside the Microgravity Science Glovebox of the International Space Station's Destiny laboratory. Results from ACE will help researchers understand how to optimize stabilizers to extend the shelf life of products like laundry detergent, paint, ketchup and even salad dressing.

Studying the use of magnetic fields to change viscosity of special fluids. Could improve brake systems, seat suspensions, robotics, clutches, engine mounts & more. The experiment is called InSPACE (Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions). KN from space

    Hi,Karen, thanks for all the pics you share w us. By any chance as you passes by Brazil take a pic and pin it. ;) thank you.

  • Dr. Linda Welker

    Karen, you've literally opened new vistas for us. POV is everything. Love the education and pleasure you bring to us. Thanks so much. Linda

Eeewwww!!!! In this episode of the ISS Science Garage, both Don and Mike discuss changes to the human body while in space.

Geared up for tele-operations with Robonaut, where my movements become his. KN from space.

On July 18, I assembled a brand new microscope to be used in the Japanese Lab of ISS. New discoveries to come! KN from space.

One of the coolest games in space: playing with water and the phenomenon of refraction. KN from space.

Ocular ultrasound, remotely guided from Houston. I appreciate that, in space, we can use water instead of gel! KN from space.

With real-time remote guidance from Houston, Luca Parmitano conducts ultrasound of my vertebrae to study changes in the spine during long duration spaceflight. KN from space.

Expedition 36 Flight Engineer Chris Cassidy works with the Seedling Growth experiment aboard the #ISS. Credit: NASA TV. Seedling Growth Experiment is an example of research in space that could reap Earth Benefits: Further understanding of how plants grow and develop at a molecular level can lead to significant advancements in agricultural production on Earth. Understanding mechanisms of plant development will support improved agricultural production and higher crop yields on Earth.
