Eight Small Satellites Will Give Us a New Look Inside Hurricanes

The same GPS technology that helps people get where they’re going in a car will soon be used in space in an effort to improve hurricane forecasting. The technology is a key capability in a NASA mission called the Cyclone Global Navigation Satellite System (CYGNSS).

The CYGNSS mission, led by the University of Michigan, will use eight micro-satellite observatories to measure wind speeds over Earth’s oceans, increasing the ability of scientists to understand and predict hurricanes. Each microsatellite observatory will make observations based on the signals from four GPS satellites.

The CYGNSS microsatellite observatories will only receive signals broadcast directly to them from GPS satellites already orbiting the Earth and the reflection of the same satellite’s signal reflected from the Earth’s surface. The CYGNSS satellites themselves will not broadcast.

The use of eight microsatellite observatories will decrease the revisit time as compared with current individual weather satellites. The spacecraft will be deployed separately around the planet, with successive satellites passing over the same region every 12 minutes.

This will be the first time that satellites can peer through heavy tropical rainfall into the middle of hurricanes and predict how intense they are before and during landfall.

As the CYGNSS and GPS constellations orbit around the Earth, the interaction of the two systems will result in a new image of wind speed over the entire tropics every few hours, compared to every few days for a single satellite.

Another advantage of CYGNSS is that its orbit is designed to measure only in the tropics…where hurricanes develop and are most often located. The focus on tropical activity means that the instruments will be able to gather much more useful data on weather systems exclusively found in the tropics. This data will ultimately be used to help forecasters and emergency managers make lifesaving decisions.

Watch Launch!

Launch of CYGNSS is scheduled for 8:24 a.m. EST on Monday, Dec. 12 from our Kennedy Space Center in Florida. CYGNSS will launch aboard an Orbital ATK Pegasus XL rocket, which will be deployed from Orbital’s “Stargazer” L-1011 carrier aircraft. 

Pegasus is a winged, three-stage solid propellant rocket that can launch a satellite into low Earth orbit. How does it work? Great question! 

After takeoff, the aircraft (which looks like a commercial airplane..but with some special quirks) flies to about 39,000 feet over the ocean and releases the rocket. 

After a five-second free fall in a horizontal position, the Pegasus first stage ignites. The aerodynamic lift, generated by the rocket’s triangle-shaped wing, delivers the payload into orbit in about 10 minutes. 

Pegasus is used to deploy small satellites weighing up to 1,000 pounds into low Earth orbit.

Meet the real women behind Hidden Figures.

Before electronic computers were common, NASA hired mathematicians like Katherine Johnson to do the computing. Even after NASA began using IBM computers to plan its missions, Astronaut John Glenn trusted Johnson’s abilities so much that he personally requested she recheck the computer calculations that helped him become the first American to orbit the Earth.

Johnson is one of the women whose work inspired the film Hidden Figures — the true story of three African American mathematicians who helped NASA launch the first Americans into space.

The polluted brain

Some of the health risks of inhaling fine and ultrafine pollutant particles are well-established, such as asthma, lung cancer, and, most recently, heart disease. But a growing body of evidence suggests that such exposure can also harm the brain, accelerating cognitive aging, and may even increase risk of Alzheimer’s disease and other forms of dementia.

Katsushika Hokusai (葛飾北斎?, outubro ou novembro de 1760 – 18 de abril de 1849) foi um artista japonês, pintor de estilo ukiyo-e e gravurista do período Edo. Em sua época, era um dos principais especialistas em pintura chinesa do Japão.[1] Nascido em Edo (atual Tóquio), Hokusai é melhor conhecido como autor da série de xilogravuras Trinta e seis vistas do monte Fuji (富嶽三十六景, Fugaku Sanjūroku-kei?, c. 1831) que inclui sua pintura icônica e internacionalmente conhecida, A Grande Onda de Kanagawa, criada durante a década de 1820.
