NASA's commercial cargo provider SpaceX is targeting 12:51 p.m. EST on Wednesday, Dec. 4, for the launch of its 19th resupply mission to the International Space Station. The uncrewed Dragon spacecraft will lift off atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. Meteorologists with the U.S. Air Force 45th Space Wing predict a 90% chance of favorable weather conditions for launch, with the primary concern being wind at the time of liftoff.

The Dragon is filled with supplies and materials that will directly support dozens of science and research investigations aboard the orbiting laboratory. It also will carry the Japanese government's Hyperspectral Imager Suite (HISUI), a next-generation, hyperspectral Earth imaging system.

Weather conditions at the surface will likely be favorable for the launch of a SpaceX Falcon 9 rocket Wednesday fr om Cape Canaveral, but upper level winds may pose a roadblock for the start of the company's next space station resupply mission.

The official launch weather forecast issued Monday by the U.S. Air Force's 45th Weather Squadron predicts a 90 percent chance of favorable weather for liftoff of a Falcon 9 rocket fr om Cape Canaveral's Complex 40 launch pad at 12:51 p.m. EST (1751 GMT) Wednesday.

But that probability only factors in weather conditions at the surface. Weather prediction models suggest winds aloft will be strong Wednesday, with maximum upper level winds forecast to be from the northwest at 110 knots near 40,000 feet.

Weather balloons sent aloft throughout the countdown Wednesday will give ground teams measurements of wind conditions at various altitudes. The actual upper level wind lim it depends on factors such as wind shears, or changes in speed and direction at different altitudes, and the capabilities of a specific rocket to safely fly through the wind shears.

Mostly sunny skies, mild temperatures and a brisk breeze from the west-northwest are forecast at the surface for Wednesday's launch opportunity. The 10 percent probability for a weather violation in the Air Force's forecast is attributed to a slight chance that surface winds might exceed the Falcon 9's wind lim it.

The Falcon 9 rocket is set to launch a Dragon supply ship to the International Space Station.

SpaceX CRS-19 Research Overview: Mighty Mice in Space

 ISS National Lab

2 дек. 2019 г.

On SpaceX CRS-19, the Jackson Laboratory is sending to station 40 female mice, including a few that lack the gene for producing myostatin, a growth factor that normally acts to limit muscle growth in both mice and humans. These mutant mice lacking myostatin, dubbed "mighty mice," develop additional muscle mass compared with normal mice. This investigation will examine the potential benefits of targeting the myostatin signaling pathway to help prevent diseases on Earth that result in muscle and bone loss. Microgravity induces rapid muscle and bone loss, providing accelerated models of disease for research aimed at improving therapeutics for patients on Earth.

SpaceX CRS-19 Research Overview: Confined Combustion

ISS National Lab

2 дек. 2019 г.

The National Science Foundation is funding an experiment fr om Case Western Reserve University that seeks to study flame spread in confined spaces, where fire can be accelerated. By doing studies in microgravity, wh ere buoyancy is eliminated, researchers can better understand the physics of flame spread, and results may help improve fire safety codes on Earth to help prevent injuries and save lives.
