Forecast 70 Percent 'Go' for Thursday Launch

Posted on May 30, 2017 at 10:12 am by Steven Siceloff.



The chance of anvil and cumulus clouds developing Thursday afternoon around launch time has Air Force meteorologists predicting a 70 percent chance of acceptable conditions for the liftoff of a SpaceX Falcon 9 rocket and Dragon spacecraft on a supply mission to the International Space Station. Launch is targeted for 5:55 p.m. EDT from Launch Complex 39A at NASA's Kennedy Space Center in Florida. The forecast for a Friday launch calls for a 60 percent chance of acceptable conditions. SpaceX conducted a static test firing of the Falcon 9 rocket, shown above, on Sunday. The detailed forecast is below.

This will be the 100th launch from LC-39A, which was the starting point for Apollo 11's landmark mission to the moon, the first space shuttle mission and five previous SpaceX flights.

The uncrewed Dragon spacecraft will be loaded with almost 6,000 pounds of science research, crew supplies and hardware for the orbiting laboratory in support of Expedition 52 and 53 crew members. The unpressurized trunk of the spacecraft also will transport solar panels, tools for Earth-observation and equipment to study neutron stars.  Known as CRS-11, this mission will be the eleventh for SpaceX under the company's contract with NASA.

Forecast details: Moisture has begun to build in aloft today, signaling the start of Central Florida's convective season. The storms will be guided by the orientation of the Bermuda Ridge axis, which is forecast to gradually shift north of the Spaceport over the next few days. A few storms may develop along the Space Coast today, and the storms will be more widespread on Wednesday as moisture continues to increase aloft. On launch day, the Bermuda Ridge axis is forecast to be north of the area, helping to steer most storms that develop inland, away from the Spaceport. Upper-level winds remain out of the northwest however, which will bring anvil clouds from inland storms back east. The primary concerns will be anvil & cumulus clouds. Max upper-level winds will be northwest at 100 kts at 45,000 ft.

On Friday, similar conditions are expected with an inland push to the storms via the steering winds. The steering direction begins to change on Saturday, increasing the probability that storms will remain along the Space Coast. The main concerns Saturday are anvil clouds, cumulus clouds, and flight through precipitation. Maximum upper-level winds will be from the northwest at 90 knots near 45,000 feet.

Studying Flame Behavior in Microgravity with a Solid "High-Five"


Microgravity conditions allow the creation of spherical flames which simplify analysis and reveal behavior that is difficult to study on Earth. Flames like this are yielding valuable information about soot formation and flame extinction.

Fire is used to heat our homes, cook our food and fuel our trips. Whether we burn fuel in our homes, vehicles, or power plants, flames play an important role in powering our lives on Earth.

Researchers fr om across the country have developed a series of experiments to expand our understanding of flames at a fundamental level. NASA's Advanced Combustion via Microgravity Experiments (ACME) project is comprised of five experiments designed to test different aspects of flames. Working with NASA's Glenn Research Center in Cleveland to conduct research on the International Space Station, the investigators will study microgravity flames burning under a range of conditions. Results of the experiments could lead to improved fuel efficiency and pollutant reduction.

"Four of ACME's experiments are designed to improve our understanding of flame behavior for practical use on Earth," said Glenn's ACME project scientist Dennis Stocker. "The other experiment is intended to help us understand and improve spacecraft fire safety."

• Coflow Laminar Diffusion Flame will extend the range of flame conditions that can be accurately predicted, especially under conditions wh ere the flame is sooty or could become unstable.
  

[/li]
• Electric-Field Effects on Laminar Diffusion Flames will investigate how an electric field can be used to control flames, through their naturally occurring ions, to reduce pollutant emission.
  

[/li]
• Structure and Response of Spherical Flames will aid in predicting the structure and dynamics of soot-free and sooty flames.
  

[/li]
• Flame Design experiment seeks to expand our understanding of soot inception and control in order to optimize oxygen enriched combustion and the design of robust and soot-free flames.
  

[/li]
• Burning Rate Emulator experiment is focused on flammability and the selection of materials for use in spacecraft.

Most of ACME's hardware will launch on SpaceX's 11th contracted cargo mission to the space station. Once in orbit, ACME tests will be conducted in the space stations' Combustion Integrated Rack. The experiments will be operated remotely from Glenn's ISS Payload Operations Center.

"The crew of the space station will se t up the hardware needed for the experiments and then they float away. ACME tests are then commanded from the ground and data is downlinked for analysis and planning of subsequent tests," said Stocker.

A microgravity environment enables researchers to explore flame behavior without the influence of gravity, so they can look at the underlying physics behind flame structure and behavior. That knowledge can help designers and engineers develop furnaces, power plants, boilers and other power systems that are more efficient and less polluting.

ACME is sponsored by the Physical Sciences Research Program with the Space Life and Physical Sciences Research and Applications Division at NASA Headquarters in Washington.

Опять у НАСА с арифметикой не в порядке - lbs сходится при сложении, а kg не сходится  (замечал проблему с арифметикой при запуске IDA-1). Проблема в числе 1665 (там другой множитель при переводе lbs в kg)
