ЦитироватьEngineers prepare NASA's eight Cyclone Global Navigation Satellite System (CYGNSS) microsatellites, mounted on the deployment module, for vibration testing at the Southwest Research Institute in San Antonio, Texas. CYGNSS will probe the inner core of hurricanes to better understand their rapid intensification.

Vibration testing will simulate the conditions that systems will undergo while attached to the Orbital-ATK "Stargazer" L-1011 carrier aircraft and subsequent launch on a Pegasus rocket. Vibration testing will wrap up in the next two weeks and be followed by preparations to ship the microsatellites and deployment module to Vandenberg Air Force Base in California for integration with the launch vehicle.

The mission is scheduled to launch Nov. 21 from Cape Canaveral Air Force Station in Florida.

Technicians prepare to install one of the fins on the Orbital ATK Pegasus XL rocket inside Building 1555 at Vandenberg Air Force Base in California. The fins will provide aerodynamic stability during flight. The rocket is being prepared at Vandenberg, and then will be transported to NASA's Kennedy Space Center in Florida attached to the Orbital ATK L-1011 carrier aircraft with NASA's Cyclone Global Navigation Satellite System (CYGNSS) in its payload fairing. CYGNSS will launch on the Pegasus XL rocket from the Skid Strip at Cape Canaveral Air Force Station. CYGNSS will make frequent and accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes. The data that CYGNSS provides will enable scientists to probe key air-sea interaction processes that take place near the core of storms, which are rapidly changing and play a critical role in the beginning and intensification of hurricanes.

Mission Update: Pegasus Flight #43 (CYGNSS)

(http://www.orbitalatk.com/news-room/feature-stories/Pegasus43_MissionPage/Images/Pegasus43_banner.jpg)
 

Launch Date:	December 12, 2016
Launch Site:	Cape Canaveral, Florida
Payload:	Cyclone Global Navigation Satellite System (CYGNSS)
Mission Customer:	NASA

About the Mission
Our Pegasus XL rocket is scheduled to launch fr om our L-1011 Stargazer aircraft on December 12, 2016. Stargazer will take off from Cape Canaveral Air Force Station at 7:26 a.m. EST, with the one-hour launch window opening at 8:19 a.m. The three-stage Pegasus XL will be used to deploy eight small satellites for NASA's Cyclone Global Navigation Satellite System (CYGNSS) mission into a Low-Earth orbit. Pegasus is carried aloft by Orbital ATK's Stargazer L-1011 aircraft to approximately 40,000 feet over the Atlantic Ocean, wh ere it will be released and free-fall for five seconds before igniting its first stage rocket motor. With its unique delta-shaped wing, Pegasus will deliver these satellites into orbit in a little over 10 minutes.
CYGNSS, developed by the University of Michigan, will probe the inner core of hurricanes to learn about their rapid intensification. CYGNSS is designed to remedy the inability of current remote sensors to see through the heavy rain in the inner core of a hurricane or to observe changes in the storm over short periods of time.

About Pegasus
On April 5, 1990, Orbital ATK began a new era in commercial space flight when our Pegasus rocket was launched from beneath a NASA B-52 aircraft in a mission that originated from Dryden Flight Research Center in California. In the decades since its maiden flight, Pegasus has become the world's standard for affordable and reliable small launch vehicles. It has conducted 42 missions, launching 86 satellites.
This patented air-launch system provides customers with unparalleled flexibility to operate from virtually anywhere on Earth with minimal ground support requirements. Pegasus launches have been conducted from six separate sites in the U.S., Europe and the Marshall Islands, the first time a space launch vehicle has demonstrated such operational flexibility. Pegasus XL is a category 3 NASA-certified vehicle.

Eight mini-satellites packed snug inside a Pegasus rocket slung under a modified jumbo jet will fire into orbit Monday off Florida's East Coast, launching on a $157 million NASA mission that could help forecasters better predict how strong hurricanes will be when they strike land.
The self-contained spacecraft are part of NASA's Cyclone Global Navigation Satellite System, or CYGNSS, a project conceived to peer through rain shafts into the cores of hurricanes and measure their winds.
Other satellites, like those equipped with microwave radars, are not sensitive enough to see through rain, and they do not pass over hurricanes often enough to yield information that might be valuable for real-time forecasting.
"Things happening in the center of a hurricane, right now, are just about impossible to measure fr om satellites for two reasons," said Chris Ruf, the CYGNSS mission's principal investigator fr om the department of climate and space sciences and engineering at the University of Michigan. "One is there is a lot of rain in hurricanes, and you can't see thorugh heavy rain with satellite remote sensing techniques. That's one.
"The other is that things in the middle of a hurricane tend to change a lot more quickly than the things that are far away fr om it," Ruf said. "Satellites don't pass over the same place often though to see those rapid changes."
Coverage from observing satellites in polar orbit is not as thorough in the tropics. In selecting such an orbit, engineers and scientists gain global coverage, but the satellite can only see winds at low latitudes once every three days, and even then can be blinded by rain.
"Those are the two things that we're trying to overcome through CYGNSS," Ruf said. "Measurement through rain and measurement more often."
Built by the Southwest Research Institute in San Antonio, each one of the CYGNSS observatories weighs just 64 pounds (29 kilograms), not much more than the weight lim it for carry-on luggage.
Mounted together on an adapter module supplied by Sierra Nevada Corp., the satellites are folded up to fit inside the envelope of their air-launched Orbital ATK Pegasus XL rocket. Once in space, they will unfurl solar panels extending around 5.5 feet (1.7 meters) across, shorter than the wing span of an average adult bald eagle.
The 55-foot-long (17-meter) rocket is fastened to the bottom of a modified L-1011 carrier airplane nicknamed "Stargazer."

Orbital ATK's launch crew assembled the three-stage Pegasus XL at Vandenberg Air Force Base in California, added the CYGNSS payloads, and connected the rocket to the L-1011 aircraft before ferrying the launcher on a transcontinental trip to Cape Canaveral on Dec. 2.
Since arriving at Cape Canaveral Air Force Station's Skid Strip, the Pegasus team has completed a combined systems test to ensure the rocket, satellite and carrier plane are all functioning as expected. The launch team conducted a launch day dress rehearsal Friday.
A launch readiness review Saturday cleared the mission for flight, pending the resolution of a minor concern with the closeout of wire ties on the winged rocket, according to Tim Dunn, NASA's launch director for the CYGNSS mission.
The L-1011 mothership, the last of the 1970s-era Lockheed-built jumbo jets still operational, will take off from Cape Canaveral shortly after 7 a.m. EST (1200 GMT) Monday, and head for a drop box over the Atlantic Ocean around 100 miles (160 kilometers) east of Daytona Beach.
Once aligned on an east-southeast heading at an altitude of 39,000 feet (11,900 meters), the crew aboard the L-1011 will activate the Pegasus rocket's steering fins, and the pilot will issue the command to drop the 51,000-pound (23-metric ton) launcher.
The drop should occur around 8:24 a.m. EST (1324 GMT) if all goes according to plan. That's five minutes into Monday's hour-long window, which extends until 9:19 a.m. EST (1419 GMT).
The expendable rocket will switch on its destruct system once clear of the aircraft, then light its solid-fueled first stage motor with 160,000 pounds of thrust around five seconds after the drop command. A top-mounted wing will provide lift to pitch the rocket's nose up, and rear-mounted fins will steer the Pegasus XL in the first minute of the flight.
Two more rocket motors will fire to put the CYGNSS satellites into orbit in less than eight minutes. The Pegasus flight computer will target an altitude of 317 miles (510 kilometers) for deployment of the satellites two-at-a-time beginning 13 minutes after launch.
Orbital ATK's Pegasus rocket has flown 42 times before, logging 28 straight successful missions going into Monday's launch. The CYGNSS mission marks the first Pegasus mission staged from Cape Canaveral since 2003, an interlude in which the air-dropped rocket continued launch services from Vandenberg and Kwajalein Atoll in the Marshall Islands.
The separation sequence should be finished by the mission's 14-and-a-half minute point.
The CYGNSS satellites will automatically unfurl their solar panels, then make first contact with ground controllers around three hours after launch, a crucial milestone when engineers will confirm the health of the spacecraft.
Early next year, the CYGNSS ground team will start maneuvering the satellites to their proper positions in a "string of pearls" orbit grouping.
The diminutive satellites do not have their own rocket engines, so engineers devised a way to use torque wheels to pivot the observatories up or down and use the force of aerodynamic drag to fine tune their orbits.
For example, tipping the satellite's orientation to expose the blunt side of its solar panels to the air flow — light but still measurable at the CYGNSS fleet's altitude — will cause the craft to slow down and change position relative to the rest of the constellation.
Once the spacing is settled, each satellite will be about 3,000 miles (5,000 kilometers) apart with their tracks taking them between 35 degrees north and south latitude on each hour-and-a-half lap around Earth.
"The vast majority of hurricanes and cyclones happen in this band between plus-and-minus 35 degrees latitude," said Aaron Ridley, CYGNSS constellation scientist at the University of Michigan. "When we decided wh ere we wanted to launch CYGNSS, we didn't need to go up to the poles. We needed to stay within this region. We chose the inclination of the satellites so that they will actually be in this region wh ere all these hurricanes and tropical cyclones have happened in the past."

Science data will be passively collected by the CYGNSS satellites as a byproduct of the continuous navigation signals broadcast by the U.S. military's Global Positioning System network.
Receivers aboard each spacecraft will listen for long-wave signals from GPS satellites bounced off the ocean's surface. The intensity of the reflected radio waves will tell scientists about the ocean's roughness, from which computer algorithms can derive an estimate of the winds causing the choppy seas.
CYGNSS is not intended to feed real-time data to hurricane forecasters, officials said. It is geared more for research and development, with objectives including the demonstration that reflected GPS signals are useful for tropical weather forecasting, and the collection of new insights into the inner workings of hurricanes.
The GPS reflections have been detected before, but have not been exploited for research.
The lessons could be applied to a future satellite mission to route data on active hurricanes to forecasters, or to improve that numerical computer models that generate tropical weather predictions.
Ruf said scientists are specifically interested in using data from CYGNSS to better predict intensity fluctuations in tropical cyclones. Such changes in strength are notoriously difficult to predict, and they could mean the difference between life and death for residents on the coast.
"For the most part, there's been little improvement in our ability to forecast how strong a hurricane is going to be, but a lot of improvement in forecasting wh ere it's going to go," Ruf said.
The only sure way to detect winds in the heart of a hurricane now is with NOAA and U.S. Air Force hurricane hunter aircraft, which fly through a storm's eyewall to directly sample the conditions at the most intense part of the cyclone.
"The limitation with this is you can only do this by getting an airplane out into the hurricane," Ruf said. "We're trying to take this type of measurement capability and extend it into space with CYGNSS."
Each CYGNSS observatory carries a doppler radar instrument — made by Surrey Satellite Technology, a Colorado-based subsidiary of Britain's Surrey Satellite Technology Ltd. — consisting of two Earth-facing antennas to gather GPS radio waves scattered off the ocean, and an antenna mounted on the opposite side of the spacecraft to collect undisturbed signals directly from the GPS satellites flying more than 12,500 miles (20,000 kilometers) above Earth.

"The GPS signals are there all the time, and what we've done with CYGNSS is we've taken a commercial navigation receiver and essentially hacked into it and modified its processor so that it does both navigation and it also measures the distortion in the navigation signal after it reflects off of the ocean surface," Ruf said. "By looking carefully at the nature of the distortion, we can back out the properties of the ocean surface that are enforced by the local winds."
Ruf compares the distortion effect to the difference between the full moon's reflection in a lake without wind, and the twinkling moonlight reflected in a breeze.
"CYGNSS is basically the receive half of a radar, and the transmit half of the radar is the GPS constellation of navigation satellites" Ruf said.
The passive nature of the CYGNSS satellites allowed designers at Southwest Research Institute, a senior partner on the mission with the University of Michigan, to simplify the spacecraft to fit the size and mass constraints of a light-class Pegasus rocket, and the tight budget imposed by NASA.
The space agency said the CYGNSS mission, sel ected in a competition in 2012, came in on schedule and on budget.
The concept of CYGNSS is "like having a broadcast radio station up in the air (with GPS), and all you have to have on-board the CYGNSS spacecraft is a small little receiver," said John Scherrer, CYGNSS project manager at SWRI.
The CYGNSS satellites were the first spacecraft of their size to be built up at SWRI's San Antonio campus, which has produced space instruments for decades, including sensors aboard NASA's New Horizons mission to Pluto and the Juno mission orbiting Jupiter.
The CYGNSS mission is approved for at least two years, but the satellites are designed to function at least five years, Scherrer said.
Each spacecraft is capable of recording and processing four reflected GPS signals simultaneously, then downlink the results to scientists via ground stations in Hawaii, Chile and Australia.
Hurricane experts fr om the National Hurricane Center plan to examine the data to determine its utility in operational forecasting. Ruf said the mission should be ready for action in time for the start of the North Atlantic hurricane season in the spring.
"With eight satellites, and with each satellite being able to make four measurements of the wind, it's kind of like having 32 virtual P-3 airplanes some place in the tropics measuring winds at all times," Ruf said.

 December 12, 2016 (http://spaceflightnow.com/2016/12/) Stephen Clark (http://spaceflightnow.com/author/stephen-clark/)
 
Orbital ATK's Pegasus XL rocket will take about eight minutes to reach orbit with NASA's eight CYGNSS weather research microsatellites, then comes deployment of the spacecraft more than 300 miles (500 kilometers) above Earth.
The 51,000-pound (23-metric ton) rocket will drop from the belly of a modified L-1011 carrier plane, named Stargazer, flying on an east-southeast path over the Atlantic Ocean at an altitude of 39,000 feet (11,900 meters).
The Pegasus rocket, launching on its 43rd orbital mission, will fire three solid-fueled stages in succession, then release the eight Cyclone Global Navigation Satellite System spacecraft two at a time.
The images below were recorded from a previous flight.

The Orion 50S XL first stage motor consumes all of its solid-fuel propellant and burns out at an altitude of more than 175,000 feet, or 53.5 kilometers.

T+01:33: First Stage Separation/Second Stage Ignition
 (https://img.novosti-kosmonavtiki.ru/155214.png) (https://img.novosti-kosmonavtiki.ru/155214.png)
The spent first stage motor is jettisoned at T+plus 1 minute, 33 seconds, to prepare for the second stage of flight. The first stage casing falls into the Atlantic Ocean. One second later, Orion 50 XL motor ignites at an altitude of 233,000 feet (71 kilometers) to continue the flight into orbit.

The 50-inch-diamter (1.3-meter) payload fairing that protected the CYGNSS satellites during atmospheric ascent is separated once heating levels drop to predetermined limits. The second stage motor continues its burn with 44,000 pounds of thrust.

T+02:48: Second Stage Burnout
 (https://img.novosti-kosmonavtiki.ru/155212.png) (https://img.novosti-kosmonavtiki.ru/155212.png)
The Orion 50 XL second stage motor consumes all its solid fuel, then begins a four-minute coast phase for the rocket to climb to the targeted altitude for the CYGNSS mission. During this time, the rocket's on-board computer calculates when it needs to ignite the third stage based on the performance of the booster to this point.
 
T+06:37: Second Stage Separation

 (https://img.novosti-kosmonavtiki.ru/155213.png) (https://img.novosti-kosmonavtiki.ru/155213.png)
The Pegasus XL's third stage Orion 38 motor fires for a planned 68-second burn to accelerate the eight CYGNSS microsatellites to orbital velocity.

T+07:56: Third Stage Burnout
 (https://img.novosti-kosmonavtiki.ru/155206.png) (https://img.novosti-kosmonavtiki.ru/155206.png)
The third stage Orion 38 solid-fueled motor burns out. The mission is targeting a circular orbit 317 miles (510 kilometers) above Earth at an inclination of 35 degrees.

The attitude control thrusters on the Pegasus XL's third stage will re-orient the vehicle for the deployment of the eight CYGNSS microsatellites, which will separate in pairs at T+plus 12 minutes, 56 seconds, T+plus 13 minutes, 26 seconds, T+plus 13 minutes, 56 seconds, and T+plus 14 minutes, 26 seconds. A ground station in Kourou, French Guiana, will be monitoring the separation events.

Orbital ATK and NASA announced today that the next launch attempt of the Pegasus rocket will be scheduled no earlier than December 14, with a launch window from 8:20 to 9:20 a.m. EST. This additional time will allow for a replacement L-1011 carrier aircraft component to arrive from Mojave, California, and be installed, as well as support the required crew rest requirements.
Today's launch was aborted due to an issue with the launch vehicle release system on the L-1011 Stargazer. The hydraulic release system operates the mechanism that releases the Pegasus rocket from the carrier aircraft. The hydraulic system had functioned properly during the pre-flight checks of the airplane.

Mission Update - December 13, 2016
The Pegasus launch of NASA's CYGNSS mission planned for Wednesday, December 14 is being delayed due to an issue with flight parameter data used by spacecraft software. The issue was discovered during routine testing on Tuesday, December 13. The new flight parameter data have undergone verification testing on the engineering model, and will be uploaded to the spacecraft on Wednesday. The uploading of new flight data is a very routine procedure, and is expected to correct the issue. The next launch attempt will be determined pending the results of ongoing tests.

The Pegasus launch of NASA's CYGNSS mission has been rescheduled for Thursday, December 15 at 8:26 a.m. EST. Live coverage on NASA TV (https://www.nasa.gov/multimedia/nasatv/index.html#public) will begin at 7:00 a.m. EST.
 
About the Mission

 The three-stage Pegasus XL will be used to deploy eight small satellites for NASA's Cyclone Global Navigation Satellite System (CYGNSS) mission into a Low-Earth orbit. Pegasus is carried aloft by Orbital ATK's Stargazer L-1011 aircraft to approximately 40,000 feet over the Atlantic Ocean, where it will be released and free-fall for five seconds before igniting its first stage rocket motor. With its unique delta-shaped wing, Pegasus will deliver these satellites into orbit in a little over 10 minutes.
CYGNSS, developed by the University of Michigan, will probe the inner core of hurricanes to learn about their rapid intensification. CYGNSS is designed to remedy the inability of current remote sensors to see through the heavy rain in the inner core of a hurricane or to observe changes in the storm over short periods of time.

About Pegasus

On April 5, 1990, Orbital ATK began a new era in commercial space flight when our Pegasus rocket was launched from beneath a NASA B-52 aircraft in a mission that originated from Dryden Flight Research Center in California. In the decades since its maiden flight, Pegasus has become the world's standard for affordable and reliable small launch vehicles. It has conducted 42 missions, launching 86 satellites.
This patented air-launch system provides customers with unparalleled flexibility to operate from virtually anywhere on Earth with minimal ground support requirements. Pegasus launches have been conducted from six separate sites in the U.S., Europe and the Marshall Islands, the first time a space launch vehicle has demonstrated such operational flexibility. Pegasus XL is a category 3 NASA-certified vehicle.

T-minus 50 minutes and counting. Stargazer is following a predetermined course commonly called "the race track" patten to reach the precise point where the Pegasus can be released for launch. This ferry flight lasts about an hour, flying east from Cape Canaveral, making a U-turn and then coming back around to launch the rocket.

ЦитироватьВАШИНГТОН, 15 дек – РИА Новости. Ракета Pegasus стартовала с малыми спутниками исследования ураганов CYGNSS, трансляцию воздушного запуска ведет сайт НАСА.

Самолет Stargazer L-1011, который выводит крылатую ракету с космическими аппаратами на необходимую для старта высоту, поднялся в воздух с мыса Канаверал в 15.35 мск. В 16.37 оператор на борту самолета выпустил ракету, через пять секунд свободного падения включился двигатель ракеты. Через 14 минут космические аппараты достигнут расчетного места на рабочей орбите. Запуск идет в штатном режиме, все системы работают исправно.

Старт Pegasus ранее дважды переносился, сначала по техническим причинам, затем из-за сбоя программного обеспечения космического корабля.

"Отделение всех восьми спутников CYGNSS подтверждено, миссия успешна, поздравляем CYGNSS!", — сообщил ведущий трансляции через 15 минут полета под аплодисменты сотрудников Центра управления полетами.

Система CYGNSS, в которую входят восемь малых спутников, предназначена для измерения силы ветра над поверхностью океана во время прохождения штормов и циклонов. Полученные данные позволят специалистам изучить взаимодействие земных океанов и воздушных масс в центре ураганов для лучшего понимания их формирование и поведения.

Ракета Pegasus является первой в мире крылатой ракетой для запуска коммерческих спутников на низкую околоземную орбиту, разработанной частной компанией. Накануне старта Orbital ATK сообщила, что технология старта с самолета обеспечивает заказчикам как возможность запуска из любой точки планеты, так и минимальные требования в отношении наземной инфраструктуры.

Для Pegasus запуск CYGNSS стал 43-м стартом при помощи самолета Stargazer L-1011, и первым полетом с мыса Канаверал за последние 13 лет. Для НАСА запуск спутников при помощи крылатой ракеты является достаточно редким событием.
