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.

We consider local news programming a service to the community, and we take that responsibility extremely seriously. So we’re always looking at different ways to wrap technology around journalism to create more timely and compelling stories and videos for viewers.

Webb 101: 10 Facts about the James Webb Space Telescope
Did you know…?
1. Our upcoming James Webb Space Telescope will act like a powerful time machine – because it will capture light that’s been traveling across space for as long as 13.5 billion years, when the first stars and galaxies were formed out of the darkness of the early universe.
2. Webb will be able to see infrared light. This is light that is just outside the visible spectrum, and just outside of what we can see with our human eyes.
3. Webb’s unprecedented sensitivity to infrared light will help astronomers to compare the faintest, earliest galaxies to today’s grand spirals and ellipticals, helping us to understand how galaxies assemble over billions of years.

4. Webb will be able to see right through and into massive clouds of dust that are opaque to visible-light observatories like the Hubble Space Telescope. Inside those clouds are where stars and planetary systems are born.
5. In addition to seeing things inside our own solar system, Webb will tell us more about the atmospheres of planets orbiting other stars, and perhaps even find the building blocks of life elsewhere in the universe.

6. Webb will orbit the Sun a million miles away from Earth, at the place called the second Lagrange point. (L2 is four times further away than the moon!)
7. To preserve Webb’s heat sensitive vision, it has a ‘sunshield’ that’s the size of a tennis court; it gives the telescope the equivalent of SPF protection of 1 million! The sunshield also reduces the temperature between the hot and cold side of the spacecraft by almost 600 degrees Fahrenheit.
8. Webb’s 18-segment primary mirror is over 6 times bigger in area than Hubble’s and will be ~100x more powerful. (How big is it? 6.5 meters in diameter.)
9. Webb’s 18 primary mirror segments can each be individually adjusted to work as one massive mirror. They’re covered with a golf ball’s worth of gold, which optimizes them for reflecting infrared light (the coating is so thin that a human hair is 1,000 times thicker!).
10. Webb will be so sensitive, it could detect the heat signature of a bumblebee at the distance of the moon, and can see details the size of a US penny at the distance of about 40 km.
BONUS! Over 1,200 scientists, engineers and technicians from 14 countries (and more than 27 U.S. states) have taken part in designing and building Webb. The entire project is a joint mission between NASA and the European and Canadian Space Agencies. The telescope part of the observatory was assembled in the world’s largest cleanroom at our Goddard Space Flight Center in Maryland.
Webb is currently being tested at our Johnson Space Flight Center in Houston, TX.
Afterwards, the telescope will travel to Northrop Grumman to be mated with the spacecraft and undergo final testing. Once complete, Webb will be packed up and be transported via boat to its launch site in French Guiana, where a European Space Agency Ariane 5 rocket will take it into space.
