SpaceX Sends Super Science to Space Station!

SpaceX is scheduled to launch its Dragon spacecraft PACKED with super cool research and technology to the International Space Station June 1 from Kennedy Space Center in Florida. New solar panels, investigations that study neutron stars and even fruit flies are on the cargo list. Let’s take a look at what other bits of science are making their way to the orbiting laboratory 250 miles above the Earth…

New solar panels to test concept for more efficient power source

Solar panels generate power well, but they can be delicate and large when used to power a spacecraft or satellites. This technology demonstration is a solar panel concept that is lighter and stores more compactly for launch than the solar panels currently in use. 

Roll-Out Solar Array (ROSA) has solar cells on a flexible blanket and a framework that rolls out like a tape measure and snap into place, and could be used to power future space vehicles.  

Investigation to Study Composition of Neutron Stars

Neutron stars, the glowing cinders left behind when massive stars explode as supernovas, contain exotic states of matter that are impossible to replicate in any lab. NICER studies the makeup of these stars, and could provide new insight into their nature and super weird behavior.

Neutron stars emit X-ray radiation, enabling the NICER technology to observe and record information about its structure, dynamics and energetics. 

Experiment to Study Effect of New Drug on Bone Loss

When people and animals spend lots of space, they experience bone density loss. In-flight exercise can prevent it from getting worse, but there isn’t a therapy on Earth or in space that can restore bone that is already lost.

The Systemic Therapy of NELL-1 for osteoporosis (Rodent Research-5) investigation tests a new drug that can both rebuild bone and block further bone loss, improving health for crew members.

Research to Understand Cardiovascular Changes

Exposure to reduced gravity environments can result in cardiovascular changes such as fluid shifts, changes in total blood volume, heartbeat and heart rhythm irregularities, and diminished aerobic capacity.

The Fruit Fly Lab-02 study will use the fruit fly (Drosophila melanogaster) to better understand the underlying mechanisms responsible for the adverse effects of prolonged exposure to microgravity on the heart. Fruit flies are effective model organisms, and we don’t mean on the fashion runway. Want to see how 1,000 bottles of fruit flies were prepared to go to space? Check THIS out.

Space Life-Support Investigation

Currently, the life-support systems aboard the space station require special equipment to separate liquids and gases. This technology utilizes rotating and moving parts that, if broken or otherwise compromised, could cause contamination aboard the station. 

The Capillary Structures investigation studies a new method of water recycling and carbon dioxide removal using structures designed in specific shapes to manage fluid and gas mixtures. 

Earth-Observation Tools

Orbiting approximately 250 miles above the Earth’s surface, the space station provides pretty amazing views of the Earth. The Multiple User System for Earth Sensing (MUSES) facility hosts Earth-viewing instruments such as high-resolution digital cameras, hyperspectral imagers, and provides precision pointing and other accommodations.

This investigation can produce data that could be used for maritime domain awareness, agricultural awareness, food security, disaster response, air quality, oil and gas exploration and fire detection.

Want to Send Your Art to the International Space Station?!

For children ages 4-12, we’re hosting an art contest! Get the details:

We are working with Boeing and SpaceX to build human spaceflight systems, like rockets and spacecraft, to take astronauts to the International Space Station. These companies will fly astronauts to orbit around Earth while we focus on plans to explore deeper into our solar system. 

Get out your art supplies and use your creative imagination to show us the present and future of traveling in space!

There are no grocery stores in space, but there may soon be farms. Very small farms that are important to a crew conducting a mission to deep space. That’s because our astronauts will need to grow some of their own food. Researchers on Earth and astronauts on the International Space Station are already showing what is needed to grow robust plants in orbit.

What would you take to space? Astronaut Suni Williams took a cutout of her dog, Gorbie, on her first mission to the International Space Station. 

Kids 4 to 12, draw what you would take and enter it in our Children’s Artwork Calendar contest! Your entry could be beamed to the space station!

Go to http://go.nasa.gov/2fvRLNf for more information about the competition’s themes, rules and deadlines plus the entry form. 

Get your parent's permission, of course!

Email your entry form and drawing to us at: ksc-connect2ccp@mail.nasa.gov

What’s On Board the Next SpaceX Cargo Launch?

Cargo and supplies are scheduled to launch to the International Space Station on Monday, July 18 at 12:45 a.m. EDT. The SpaceX Dragon cargo spacecraft will liftoff from our Kennedy Space Center in Florida.

Among the arriving cargo is the first of two international docking adapters, which will allow commercial spacecraft to dock to the station when transporting astronauts in the near future as part of our Commercial Crew Program.

This metallic ring, big enough for astronauts and cargo to fit through represents the first on-orbit element built to the docking measurements that are standardized for all the spacecraft builders across the world.

Its first users are expected to be the Boeing Starliner and SpaceX Crew Dragon spacecraft, which are both now in development.

What About the Science?!

Experiments launching to the station range from research into the effects of microgravity on the human body, to regulating temperature on spacecraft. Take a look at a few:

A Space-based DNA Sequencer

DNA testing aboard the space station typically requires collecting samples and sending them back to Earth to be analyzed. Our Biomolecule Sequencer Investigation will test a new device that will allow DNA sequencing in space for the first time! The samples in this first test will be DNA from a virus, a bacteria and a mouse.

How big is it? Picture your smartphone…then cut it in half. This miniature device has the potential to identify microbes, diagnose diseases and evaluate crew member health, and even help detect DNA-based life elsewhere in the solar system.

OsteoOmics

OsteoOmics is an experiment that will investigate the molecular mechanisms that dictate bone loss in microgravity. It does this by examining osteoblasts, which form bone; and osteoclasts, which dissolves bone. New ground-based studies are using magnetic levitation equipment to simulate gravity-related changes. This experiment hopes to validate whether this method accurately simulates the free-fall conditions of microgravity.

Results from this study could lead to better preventative care or therapeutic treatments for people suffering bone loss, both on Earth and in space!

Heart Cells Experiment

The goals of the Effects of Microgravity on Stem Cell-Derived Heart Cells (Heart Cells) investigation include increasing the understanding of the effects of microgravity on heart function, the improvement of heart disease modeling capabilities and the development of appropriate methods for cell therapy for people with heart disease on Earth.

Phase Change Material Heat Exchanger (PCM HX)

The goal of the Phase Change Material Heat Exchanger (PCM HX) project is to regulate internal spacecraft temperatures. Inside this device, we're testing the freezing and thawing of material in an attempt to regulate temperature on a spacecraft. This phase-changing material (PCM) can be melted and solidified at certain high heat temperatures to store and release large amounts of energy.

Watch Launch!

Live coverage of the SpaceX launch will be available starting at 11:30 p.m. EDT on Sunday, July 17 via NASA Television.

SpaceX Dragon: What’s Onboard?

SpaceX is scheduled to launch its Dragon spacecraft into orbit on April 8, which will be the company’s eighth mission under our Commercial Resupply Services contract. This flight will deliver science and supplies to the International Space Station.

The experiments headed to the orbiting laboratory will help us test the use of an expandable space habitat in microgravity, assess the impact of antibodies on muscle wasting in a microgravity environment, use microgravity to seek insight into the interactions of particle flows at the nanoscale level and use protein crystal growth in microgravity to help in the design of new drugs to fight disease. Here’s an in-depth look at each of them:

The Bigelow Expandable Activity Module (BEAM)

Space is in limited supply on the International Space Station, but with BEAM, the amount of crew space could be expanded! BEAM is an experimental expandable capsule that attaches to the space station. After installation, it will expand to roughly 13-feet long and 10.5 feet in diameter, which would provide a large volume where a crew member could enter. During the two-year test mission, astronauts will enter the module for a few hours three-to-four times a year to retrieve sensor data and conduct assessments of the module’s condition.

Why? Expandable habitats greatly decrease the amount of transport volume at launch for future space missions. They not only take up less room on a rocket, but also provide greatly enhanced space for living and working once they are set up.

The Rodent Research-3-Eli Lilly

The Rodent Research-3-Eli Lilly investigation will use mice as a model for human health to study whether certain drugs might prevent muscle or bone loss while in microgravity.

Why? Crew members experience significant decreases in their bone density and muscle mass during spaceflight if they do not get enough exercise during long-duration missions. The results could expand scientist’s understanding of muscle atrophy and bone loss in space, by testing an antibody that has been known to prevent muscle wasting in mice on Earth.

Microbial Observatory-1

The Microbial Observatory-1 experiment will track and monitor changes to microbial flora over time on the space station.

Why? Obtaining data on these microbial flora could help us understand how such microbes could affect crew health during future long-duration missions.

Micro-10

The Micro-10 investigation will study how the stress of microgravity triggers changes in growth, gene expression, physical responses and metabolism of a fungus called Aspergillus nidulans.

Why? This experiment will study fungi in space for the purpose of potentially developing new medicine for use both in space and on Earth. The stressfull environment of space causes changes to all forms of life, from bacteria and fungi, to animals and people.

Genes in Space-1

Genes in Space-1 is a student-designed experiment that will test whether the polymerase chain reaction (PCR) — which is a fast and relatively inexpensive technique that can amplify or “photocopy” small segments of DNA — could be used to study DNA alterations that crew experience during spaceflight.

Why? In space, the human immune system’s function is altered. Findings from this experiment could help combat some of the DNA changes that crew onboard space station experience while on orbit.

Microchannel Diffusion

Nano science and nanotechnology are the study and application of exceptionally small things and can be used across the fields of medicine, biology, computer science and many others. The way fluid moves is very different on this small scale, so scientists want to know how microparticles might interact. The Microchannel Diffusion investigation simulates these interactions by studying them at a larger scale, the microscopic level. This is only possible on the orbiting laboratory, where Earth’s gravity is not strong enough to interact with the molecules in a sample, so they behave more like they would at the nanoscale.

Why? Nanofluidic sensors could measure the air in the space station, or used to deliver drugs to specific places in the body, among other potential uses. Knowledge learned from this investigation may have implications for drug delivery, particle filtration and future technological applications for space exploration.

The CASIS Protein Crystal Growth 4 (CASIS PCG 4)

CASIS PCG 4 is made up of two investigations that both leverage the microgravity environment in the growth of protein crystals and focus on structure-based drug design (SBDD). Growing crystals in microgravity avoids some of the obstacles they face on Earth, such as sedimentation.

Why? SBDD is an integral component in the drug discovery and development process. It relies on three-dimensional, structural information provided by the protein crystallography to inform the design of more potent, effective and selective drugs.

Watch the Launch!

The Dragon capsule will launch on a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida.

Launch coverage begins at 3:15 p.m. EDT, with launch scheduled for 4:43 p.m. Watch live online on NASA Television: nasa.gov/nasatv
