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.
CYGNSS launched at 8:37 a.m. EST on Thursday, Dec. 15, from our Kennedy Space Center in Florida. CYGNSS launched aboard an Orbital ATK Pegasus XL rocket, 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.

This week, 10 things you need to know about this beautiful nighttime show and how to catch a front-row seat.
In this 30 second exposure, a meteor streaks across the sky during the annual Perseid meteor shower Friday, Aug. 12, 2016 in Spruce Knob, West Virginia. The Perseids show up every year in August when Earth ventures through trails of debris left behind by an ancient comet. Image Credit: NASA/Bill Ingalls
With very fast and bright meteors, Perseids (pronounced PURR-see-ids) frequently leave long "wakes" of light and color behind them as they streak through Earth's atmosphere. Perseids are one of the most plentiful showers, with between 50-100 meteors seen each hour, and occur with warm summer nighttime weather, allowing sky watchers to easily view them.
You can see the Perseids this year between now and Aug. 24, 2017, but mark your calendars for peak dates Aug. 12 and 13. This year, the waning gibbous moon rises about midnight local time, which will cut the expected rates in half this year (25 to 50 per hour at the peak from a very dark sky). But the Perseids are so bright and numerous that it should still be a good show.
The Perseids (and every meteor shower) are best viewed in the Northern Hemisphere between 11 p.m. - 3 a.m. Come prepared with a sleeping bag, blanket or lawn chair.
Find an area well away from city or street lights and set up where you're shadowed from the moon's glare. Face whatever direction you like, ideally the one unobstructed by trees, buildings or moonlight. Look up, taking in as much of the sky as possible. If you have a group, each person should look in different parts of the sky. After about 30 minutes in the dark, your eyes will adapt, and you'll begin to see fainter objects, including meteors. Be patient; the show will last until dawn, so you have plenty of time to catch a glimpse.
Pack a baseball cap and wear it sideways to cover any glare from the moon. The waning gibbous moon will block out many of the fainter meteors this year, but the Perseids are so bright and numerous that it should still be a good show.
Where do meteors come from? Some originate from leftover comet particles and bits of broken asteroids. When comets come around the sun, they leave a dusty trail behind them. Every year, Earth passes through these debris trails, which allows the bits to collide with our atmosphere and disintegrate to create fiery and colorful streaks in the sky. But the vast majority of meteors don't come from meteor showers—instead, they randomly fall all of the time.
The pieces of space debris that interact with our atmosphere to create the Perseids originate from Comet 109P/Swift-Tuttle. Swift-Tuttle takes 133 years to orbit the sun once, and Comet Swift-Tuttle last visited the inner solar system in 1992. Swift-Tuttle is a large comet: its nucleus is 16 miles (26 kilometers) across. This is almost twice the size of the object hypothesized to have wiped out the dinosaurs.
Comet Swift-Tuttle was discovered in 1862 by Lewis Swift and Horace Tuttle. In 1865, Giovanni Schiaparelli realized that this comet was the source of the Perseids.
The Perseids are known for fireballs, which are large explosions of light and color that last longer than an average meteor streak. Why? They originate from bigger particles of cometary material.
The point in the sky from which the Perseids appear to come from—also known as their radiant—is the constellation Perseus. But don't get confused: The constellation name only helps viewers figure out which shower they're viewing on a given night; it's not the source of the meteors (see #6 for that answer!).

This natural-color image shows smoke from fires in the Amazon rainforest spreading across several states within Brazil, including Amazonas, Mato Grosso, and Rondônia. The image was collected by our VIIRS (Visible Infrared Imaging Radiometer Suite) instrument aboard the Suomi NPP satellite (a joint-partnership between NASA and the National Oceanic and Atmospheric Administration) on August 20, 2019. It’s not unusual to see fires in Brazil at this time of year, but activity in the country’s largest state, Amazonas, has been above average. Many people use fire to maintain farmland and pastures or to clear land for other purposes.

Saturn's hazy moon Titan is larger than Mercury, but its size is not the only way it's like a planet. Titan has a thick atmosphere, complete with its own "water cycle" -- except that it's way too cold on Titan for liquid water. Instead, rains of liquid hydrocarbons like ethane and methane fall onto icy mountains, run into rivers, and gather into great seas. Our Cassini spacecraft mapped the methane seas with radar, and its cameras even caught a glimpse of sunlight reflecting off the seas' surface. Learn more about Titan: saturn.jpl.nasa.gov/science/titan/
Jupiter's moon Ganymede is the largest in the solar system. It's bigger than Mercury and Pluto, and three-quarters the size of Mars. It's also the only moon known to have its own magnetic field. Details: solarsystem.nasa.gov/planets/ganymede/indepth
Triton is Neptune's largest moon, and the only one in the solar system to orbit in the opposite direction of its planet's rotation, a retrograde orbit. It may have been captured from the Kuiper Belt, where Pluto orbits. Despite the frigid temperatures there, Triton has cryovolcanic activity -- frozen nitrogen sometimes sublimates directly to gas and erupts from geysers on the surface. More on Triton: solarsystem.nasa.gov/planets/triton/indepth
The most famous geysers in our solar system (outside of those on Earth) belong to Saturn's moon Enceladus. It's a small, icy body, but Cassini revealed this world to be one of the solar system's most scientifically interesting destinations. Geyser-like jets spew water vapor and ice particles from an underground ocean beneath the icy crust of Enceladus. With its global ocean, unique chemistry and internal heat, Enceladus has become a promising lead in our search for worlds where life could exist. Get the details: saturn.jpl.nasa.gov/science/enceladus/
Jupiter's moon Io is subjected to tremendous gravitational forces that cause its surface to bulge up and down by as much as 330 feet (100 m). The result? Io is the most volcanically active body in the Solar System, with hundreds of volcanoes, some erupting lava fountains dozens of miles high. More on Io’s volcanoes: solarsystem.nasa.gov/planets/io/indepth
When Giovanni Cassini discovered Iapetus in 1671, he observed that one side of this moon of Saturn was bright and the other dark. He noted that he could only see Iapetus on the west side of Saturn, and correctly concluded that Iapetus had one side much darker than the other side. Why? Three centuries later, the Cassini spacecraft solved the puzzle. Dark, reddish dust in Iapetus's orbital path is swept up and lands on the leading face of the moon. The dark areas absorb energy and become warmer, while uncontaminated areas remain cooler. Learn more: saturn.jpl.nasa.gov/news/2892/cassini-10-years-at-saturn-top-10-discoveries/#nine
At half the size of Pluto, Charon is the largest of Pluto's moons and the largest known satellite relative to its parent body. The moon is so big compared to Pluto that Pluto and Charon are sometimes referred to as a double planet system. Charon's orbit around Pluto takes 6.4 Earth days, and one Pluto rotation (a Pluto day) takes 6.4 Earth days. So from Pluto's point of view Charon neither rises nor sets, but hovers over the same spot on Pluto's surface, and the same side of Charon always faces Pluto.

Saturn's moon Mimas has one feature that draws more attention than any other: the crater Herschel, which formed in an impact that nearly shattered the little world. Herschel gives Mimas a distinctive look that prompts an oft-repeated joke. But, yes, it's a moon. More: olarsystem.nasa.gov/planets/mimas
In mythology, Mars is a the god of war, so it's fitting that its two small moons are called Phobos, "fear," and Deimos, "terror." Our Mars Reconnaissance Orbiter caught this look at Phobos, which is roughly 17 miles (27 km) wide. In recent years, NASA scientists have come to think that Phobos will be torn apart by its host planet's gravity. Details: www.nasa.gov/feature/goddard/phobos-is-falling-apart

Although decades have passed since astronauts last set foot on its surface, Earth's moon is far from abandoned. Several robotic missions have continued the exploration. For example, this stunning view of the moon's famous Tycho crater was captured by our Lunar Reconnaissance Orbiter, which continues to map the surface in fine detail today.

Our @NASAJuno spacecraft's JunoCam captured images of the chaotic, stormy northern hemisphere of Jupiter during its 24th close pass of the giant planet on Dec. 26, 2019. Using data from the flyby, citizen scientist Kevin M. Gill created this color-enhanced image. At the time, the spacecraft was about 14,600 miles (23,500 kilometers) from the tops of Jupiter’s clouds, at a latitude of about 69 degrees north.

When NASA astronauts return to the Moon through Artemis, they will benefit from decades of innovation, research, and technological advancements. We’ll establish long-term lunar science and exploration capabilities at the Moon and inspire a new generation of explorers—the Artemis Generation.
Meet the Space Launch System rocket, or SLS. This next-generation super heavy-lift rocket was designed to send astronauts and their cargo farther into deep space than any rocket we’ve ever built. During liftoff, SLS will produce 8.8 million pounds (4 million kg) of maximum thrust, 15 percent more than the Saturn V rocket.
SLS will launch the Orion spacecraft into deep space. Orion is the only spacecraft capable of human deep space flight and high-speed return to Earth from the vicinity of the Moon. More than just a crew module, Orion has a launch abort system to keep astronauts safe if an emergency happens during launch, and a European-built service module, which is the powerhouse that fuels and propels Orion and keeps astronauts alive with water, oxygen, power, and temperature control.
Orion and SLS will launch from NASA’s Kennedy Space Center in Florida with help from Exploration Ground Systems (EGS) teams. EGS operates the systems and facilities necessary to process and launch rockets and spacecraft during assembly, transport, launch, and recovery.
The knowledge we've gained while operating the International Space Station has opened new opportunities for long-term exploration of the Moon's surface. Gateway, a vital component of our Artemis plans, is a Moon-orbiting space station that will serve as a staging post for human expeditions to the lunar surface. Crewed and uncrewed landers that dock to Gateway will be able to transport crew, cargo, and scientific equipment to the surface.
Our astronauts will need a place to live and work on the lunar surface. Artemis Base Camp, our first-ever lunar science base, will include a habitat that can house multiple astronauts and a camper van-style vehicle to support long-distance missions across the Moon’s surface. Apollo astronauts could only stay on the lunar surface for a short while. But as the Artemis base camp evolves, the goal is to allow crew to stay at the lunar surface for up to two months at a time.
The Apollo Program gave humanity its first experience traveling to a foreign world. Now, America and the world are ready for the next era of space exploration. NASA plans to send the first woman and first person of color to the lunar surface and inspire the next generation of explorers.
Our next adventure starts when SLS and Orion roar off the launch pad with Artemis I. Together with commercial and international partners, NASA will establish a long-term presence on the Moon to prepare for missions to Mars. Everything we’ve learned, and everything we will discover, will prepare us to take the next giant leap: sending the first astronauts to Mars.

Artemis I will be the first integrated flight test of the Space Launch System (SLS) rocket and Orion spacecraft: the rocket and spacecraft that will send future astronauts to the Moon!
Before we embark on the uncrewed Artemis I mission to the Moon and back, the rocket and spacecraft will need to undergo a test at the launch pad called a “wet dress rehearsal.” This test will take the team at NASA’s Kennedy Space Center in Florida through every step of the launch countdown, including filling the rocket’s tanks with propellant.
But in the meantime, you can take a closer look at SLS and the Orion spacecraft by downloading the 3D model for free on the NASA app! You can view the SLS model in augmented reality by placing it virtually in your own environment – on your desk, for example. Or standing beside your family pet!
SLS and Orion join more than 40 other 3D models in the app, including BioSentinel, one of 10 CubeSats flying aboard Artemis I.
