KENNEDY SPACE CENTER, FL – A SpaceX Dragon commercial cargo spacecraft docked autonomously to the International Space Station, Saturday morning, July 16, delivering three tons of NASA science and supplies to the 7-person crew serving aboard, just a day and a half after the stunning post sunset liftoff from NASA’s Kennedy Space Center in Florida that spawned a spectacular ‘Space Jellyfish’ high over the Space Coast on Thursday evening, July 14.
The two craft linked up while traveling more than 267 miles over the South Atlantic Ocean as Dragon docked to the forward-facing port of the station’s Harmony module at 11:21 a.m. EDT (1521 GMT), Saturday, July 16.
Mission controllers at NASA Johnson in Houston and SpaceX in Hawthorne tracked and worked the rendezvous and docking operation
The SpaceX cargo Dragon was jam packed with some 5800 pounds (2600 kg) of groundbreaking science and critical crew supplies.
The @SpaceX #Dragon docked to the station at 11:21am ET today. The Exp 67 crew will soon open the hatch and begin unloading over 5,800 pounds of new science experiments and crew supplies. https://t.co/Vf1Womiwfk

Among the unpressurized cargo in the Dragon trunk is the $118 million EMIT dust monitoring experiment which will for the first time determine the composition of the fine dust grains in Earth’s atmosphere and help determine whether they alternatively cool or heat the atmosphere – significantly aiding climate change research.
After Dragon spends about one month attached to the space station, the spacecraft will return to Earth with cargo and research.
The NASA SpaceX Falcon 9 and Cargo Dragon lifted off on SpaceX’s 25th NASA contracted Commercial Resupply Services (CRS-25) mission to the International Space Station since 2012 during an instantaneous launch window at 8:44 p.m. EST Thursday, July 14, (0044 GMT, July 15), from historic Launch Complex 39A (LC-39A) at the Kennedy Space Center in Florida.
Expected rainstorms and clouds luckily veered away to the north and south of the KSC launch pad – offering a crystal clear and minutes long view of the magnificent ‘Space Jellyfish’ sky show as the Falcon 9 rocket rose from twilight into daylight and formed as the expanding plume of rocket exhaust particles was illuminated by sunlight.
For at least a minute the space jellyfish – also looking like a space nebula – appeared to come to life and swim across the sky – arcing over as the rocket normally does to follow the curvature of the Earth
Even the stage separation of the first and second stages was easily visible to the naked eye as a pair of bright lights.
The SpaceX Falcon 9 and Cargo Dragon stack standing 215-feet-tall (65-meters) launched on a northeasterly trajectory along the U.S. East coast at a 51 degree inclination to the equator in line with the orbital plane of the ISS to meet up with it.
In another remarkable achievement SpaceX landed the spent first stage on the ‘A Shortfall of Gravitas ‘ (ASOG) droneship off the coast of the Carolinas in the Atlantic Ocean.
To date SpaceX has launched 164 Falcon 9 rockets since 2010 and it’s the 106th launch of a reused booster
The recycled Cargo Dragon resupply spacecraft launched on its third resupply flight to the ISS.
The SpaceX Dragon CRS-25 resupply craft is loaded with some 5,881 pounds (2,668 kilograms) pounds of science experiments, crew supplies, fresh fruit, food and vegetables, water, clothing, and other cargo for delivery to the seven person crew Expedition 67 crew of astronauts and cosmonauts living and working aboard from NASA, ESA and Roscosmos

Here is a NASA description of some of the science experiments Dragon is delivering to the space station:
Mapping Earth’s Dust
The Earth Surface Mineral Dust Source Investigation (EMIT), developed by NASA’s Jet Propulsion Laboratory in Southern California, employs NASA imaging spectroscopy technology to measure the mineral composition of dust in Earth’s arid regions. Mineral dust blown into the air can travel significant distances and affect Earth’s climate, weather, vegetation, and more. For example, dust containing dark minerals that absorb sunlight can warm an area, while light-colored mineral dust can cool it. Blowing dust also affects air quality, surface conditions such as rate of snow melt, and phytoplankton health in the ocean. The investigation collects images for one year to generate maps of the mineral composition in the regions on Earth that produce dust. Such mapping could advance our understanding of the effects of mineral dust on human populations now and in the future.

Speedier Immune System Aging
Aging is associated with changes in the immune response known as immunosenescence. Microgravity causes changes in human immune cells that resemble this condition, but happen faster than the actual process of aging on Earth. The Immunosenescence investigation, sponsored the by International Space Station U.S. National Laboratory, uses tissue chips to study how microgravity affects immune function during flight and whether immune cells recover post-flight. Tissue chips are small devices that contain human cells in a 3D structure, allowing scientists to test how those cells respond to stresses, drugs, and genetic changes.
Soil in Space
On Earth, complex communities of microorganisms carry out key functions in soil, including cycling of carbon and other nutrients and supporting plant growth. Dynamics of Microbiomes in Space sponsored by NASA’s Division of Biological and Physical Sciences, examines how microgravity affects metabolic interactions in communities of soil microbes. This research focuses on microbe communities that decompose chitin, a natural carbon polymer on Earth.
High School Student Weather Study
BeaverCube is an education mission that will teach high school students aerospace science by having them design a CubeSat. BeaverCube will host one visible and two infrared imagers to measure cloud properties, ocean surface temperatures, and ocean color to study Earth’s climate and weather systems. It also will demonstrate an application for the use of shape memory alloy technology via an in-orbit calibration technique.
Genes, No Cells
Cell-free technology is a platform for producing protein without specialized equipment of living cells that need to be cultured. Genes in Space-9, sponsored by the National Lab, demonstrates cell-free production of protein in microgravity and evaluates two cell-free biosensors that can detect specific target molecules. This technology could provide a simple, portable, and low-cost tool for medical diagnostics, on-demand production of medicine and vaccines, and environmental monitoring on future space missions.
Biopolymer Research for In-Situ Capabilities looks at how microgravity affects the process of creating a concrete alternative made with an organic material and on-site materials, such as lunar or Martian dust, known as a biopolymer soil composite. Using resources available where construction takes place makes it possible to increase the amount of shielding.
These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars through NASA’s Artemis program.
SpaceX is under contract with NASA for another 10 resupply missions in the future through CRS-35 after six more were recently added
