NASA's Juno Spacecraft Breaks Solar Power Distance Record

NASA's Juno mission to Jupiter has broken the record to become humanity's most distant solar-powered emissary. The milestone occurred at 11 a.m. PST (2 p.m. EST, 19:00 UTC) on Wednesday, Jan. 13, when Juno was about 493 million miles (793 million kilometers) from the sun.

The previous record-holder was the European Space Agency's Rosetta spacecraft, whose orbit peaked out at the 492-million-mile (792-million-kilometer) mark in October 2012, during its approach to comet 67P/Churyumov-Gerasimenko.

"Juno is all about pushing the edge of technology to help us learn about our origins," said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio. "We use every known technique to see through Jupiter's clouds and reveal the secrets Jupiter holds of our solar system's early history. It just seems right that the sun is helping us learn about the origin of Jupiter and the other planets that orbit it."

Launched in 2011, Juno is the first solar-powered spacecraft designed to operate at such a great distance from the sun. That's why the surface area of solar panels required to generate adequate power is quite large. The four-ton Juno spacecraft carries three 30-foot-long (9-meter) solar arrays festooned with 18,698 individual solar cells. At Earth distance from the sun, the cells have the potential to generate approximately 14 kilowatts of electricity. But transport those same rectangles of silicon and gallium arsenide to a fifth rock from the sun distance, and it's a powerfully different story.

"Jupiter is five times farther from the sun than Earth, and the sunlight that reaches that far out packs 25 times less punch," said Rick Nybakken, Juno's project manager from NASA's Jet Propulsion Laboratory in Pasadena, Calif. "While our massive solar arrays will be generating only 500 watts when we are at Jupiter, Juno is very efficiently designed, and it will be more than enough to get the job done."

Prior to Juno, eight spacecraft have navigated the cold, harsh underlit realities of deep space as far out as Jupiter. All have used nuclear power sources to get their job done. Solar power is possible on Juno due to improved solar-cell performance, energy-efficient instruments and spacecraft, a mission design that can avoid Jupiter's shadow, and a polar orbit that minimizes the total radiation. Juno's maximum distance from the sun during its 16-month science mission will be about 517 million miles (832 million kilometers), an almost five percent increase in the record for solar-powered space vehicles.

"It is cool we got the record and that our dedicated team of engineers and scientists can chalk up another first in space exploration," said Bolton. "But the best is yet to come. We are achieving these records and venturing so far out for a reason -- to better understand the biggest world in our solar system and thereby better understand where we came from."

Juno will arrive at Jupiter on July 4 of this year. Over the next year the spacecraft will orbit the Jovian world 33 times, skimming to within 3,100 miles (5,000 kilometers) above the planet's cloud tops every 14 days. During the flybys, Juno will probe beneath the obscuring cloud cover of Jupiter and study Jupiter's aurorae to learn more about the planet's origins, structure, atmosphere and magnetosphere.

NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. Juno is part of NASA's New Frontiers Program, which is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space Systems, Denver, built the spacecraft. The California Institute of Technology in Pasadena manages JPL for NASA.

New Details on Ceres Seen in Dawn Images

Features on dwarf planet Ceres that piqued the interest of scientists throughout 2015 stand out in exquisite detail in the latest images from NASA's Dawn spacecraft, which recently reached its lowest-ever altitude at Ceres.

Dawn took these images near its current altitude of 240 miles (385 kilometers) from Ceres, between Dec. 19 and 23, 2015.

Kupalo Crater, one of the youngest craters on Ceres, shows off many fascinating attributes at the high image resolution of 120 feet (35 meters) per pixel. The crater has bright material exposed on its rim, which could be salts, and its flat floor likely formed from impact melt and debris. Researchers will be looking closely at whether this material is related to the "bright spots" of Occator Crater. Kupalo, which measures 16 miles (26 kilometers) across and is located at southern mid-latitudes, is named for the Slavic god of vegetation and harvest.

"This crater and its recently-formed deposits will be a prime target of study for the team as Dawn continues to explore Ceres in its final mapping phase," said Paul Schenk, a Dawn science team member at the Lunar and Planetary Institute, Houston.

Dawn's low vantage point also captured the dense network of fractures on the floor of 78-mile-wide (126-kilometer-wide) Dantu Crater. One of the youngest large craters on Earth's moon, called Tycho, has similar fractures. This cracking may have resulted from the cooling of impact melt, or when the crater floor was uplifted after the crater formed.

A 20-mile (32-kilometer) crater west of Dantu is covered in steep slopes, called scarps, and ridges. These features likely formed when the crater partly collapsed during the formation process. The curvilinear nature of the scarps resembles those on the floor of Rheasilvia, the giant impact crater on protoplanet Vesta, which Dawn orbited from 2011 to 2012.

Dawn's other instruments also began studying Ceres intensively in mid-December. The visible and infrared mapping spectrometer is examining how various wavelengths of light are reflected by Ceres, which will help identify minerals present on its surface.

Dawn's gamma ray and neutron detector (GRaND) is also keeping scientists busy. Data from GRaND help researchers understand the abundances of elements in Ceres' surface, along with details of the dwarf planet's composition that hold important clues about how it evolved.

The spacecraft will remain at its current altitude for the rest of its mission, and indefinitely afterward. The end of the prime mission will be June 30, 2016.

"When we set sail for Ceres upon completing our Vesta exploration, we expected to be surprised by what we found on our next stop. Ceres did not disappoint," said Chris Russell, principal investigator for the Dawn mission, based at the University of California, Los Angeles. "Everywhere we look in these new low- altitude observations, we see amazing landforms that speak to the unique character of this most amazing world."

Dawn is the first mission to visit a dwarf planet, and the first mission outside the Earth-moon system to orbit two distinct solar system targets. After orbiting Vesta for 14 months in 2011 and 2012, it arrived at Ceres on March 6, 2015.

Dawn's mission is managed by the Jet Propulsion Laboratory for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science. Orbital ATK Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, Max Planck Institute for Solar System Research, Italian Space Agency and Italian National Astrophysical Institute are international partners on the mission team.

Jason-3 Launches to Monitor Global Sea Level Rise

Jason-3, a U.S.-European oceanography satellite mission with NASA participation that will continue a nearly quarter-century record of tracking global sea level rise, lifted off from Vandenberg Air Force Base in California Sunday at 10:42 a.m. PST (1:42 p.m. EST) aboard a SpaceX Falcon 9 rocket.

Jason-3 is an international mission led by the National Oceanic and Atmospheric Administration (NOAA) in partnership with NASA, the French space agency CNES, and the European Organisation for the Exploitation of Meteorological Satellites.

"Jason-3 will take the pulse of our changing planet by gathering environmental intelligence from the world's oceans," said Stephen Volz, assistant administrator for NOAA's Satellite and Information Service.

The mission will improve weather, climate and ocean forecasts, including helping NOAA's National Weather Service and other global weather and environmental forecast agencies more accurately forecast the strength of tropical cyclones.

"Jason-3 is a prime example of how our nation leverages NASA's expertise in space and scientific exploration to help address critical global challenges in collaboration with NOAA and our international partners," said John Grunsfeld, associate administrator for science at NASA Headquarters in Washington. "The measurements from Jason-3 will advance our efforts to understand Earth as an integrated system by increasing our knowledge of sea level changes and the ocean's roles in climate."

Minutes after Jason-3 separated from the rocket's second stage, the spacecraft unfolded its twin sets of solar arrays. Ground controllers successfully acquired the spacecraft's signal, and initial telemetry reports showed the satellite was in good health.

Jason-3 entered orbit about 16 miles (25 kilometers) below Jason-2. The new spacecraft will gradually raise itself into the same 830-mile (1,336-kilometer) orbit and position itself to follow Jason-2's ground track, orbiting about a couple of minutes behind Jason-2. The two spacecraft will fly in formation, making nearly simultaneous measurements for about six months to allow scientists to precisely calibrate Jason-3's instruments.

Jason-3 will begin full science operations after a six-month checkout phase, joining Jason-2, which launched in 2008. From low-Earth orbit, Jason-3 will precisely measure the height of 95 percent of the world's ice-free ocean every 10 days.

Coordinating orbits and combining measurements from Jason-2 and Jason-3 should allow even more frequent coverage of the global ocean. Together, the two spacecraft will double global data coverage. This tandem mission will improve our knowledge of tides in coastal and shallow seas and internal tides in the open ocean, while improving our understanding of ocean currents and eddies.

Measurements of sea-surface height, or ocean-surface topography, reveal the speed and direction of ocean currents and tell scientists how much of the sun's energy is stored by the ocean. Combining ocean current and heat storage data is key to understanding global climate changes.

Since the Topex/Poseidon-Jason satellite missions began in 1992, researchers have observed a total global sea level rise of 2.8 inches (70 millimeters) - an average rate of 0.12 inches (3 millimeters) a year. Because it is a measure of both ocean warming and loss of land ice, sea level rise is an important indicator of human-caused climate change.

"As human-caused global warming drives sea levels higher and higher, we are literally reshaping the surface of our planet," said Josh Willis, NASA project scientist for Jason-3 at NASA's Jet Propulsion Laboratory in Pasadena, California. "These missions tell us how much and how fast."

Data from Jason-3 will be used for other scientific, commercial and operational applications, including modeling of deep-ocean waves; forecasts of surface waves for offshore operators; forecasts of tides and currents for commercial shipping and ship routing; coastal forecasts to respond to environmental challenges such as oil spills and harmful algal blooms; coastal modeling crucial for marine mammal and coral reef research; and forecasts of El Niño and La Niña events.

CNES provided the Jason-3 spacecraft bus. NASA and CNES are jointly providing the primary payload instruments. NASA's Launch Services Program at the Kennedy Space Center in Florida is responsible for launch management and countdown operations for the SpaceX Falcon 9 rocket. JPL manages the mission for NASA's Science Mission Directorate, Washington.

Jason-3 in Orbit

Update: January 17, 2016 10:50am PST
The Jason-3 satellite has lifted off from Vandenberg Air Force Base, California, on board SpaceX's Falcon 9 rocket. In about an hour, it will separate from the rocket and begin deploying its two solar arrays.

---

The Jason-3 international oceanography satellite mission is scheduled for launch from Vandenberg Air Force Base in central California on Sunday, Jan. 17. Liftoff aboard a SpaceX Falcon 9 rocket from Vandenberg's Space Launch Complex 4 East is targeted for 10:42:18 a.m. PST (1:42:18 p.m. EST) at the opening of a 30-second launch window. If needed, a backup launch opportunity is available on Monday, Jan. 18 at 10:31:04 a.m. PST (1:31:04 p.m. EST).

Jason-3 will add to a 23-year satellite record of global sea surface heights, a measurement with scientific, commercial and practical applications related to climate change, currents and weather. Jason-3 data will be used for monitoring global sea level rise, researching human impacts on oceans, aiding prediction of hurricane intensity, and operational marine navigation. The mission is planned to last at least three years, with a goal of five years. It is a four-agency international partnership of the National Oceanic and Atmospheric Administration (NOAA), NASA, the French Space Agency CNES (Centre National d'Etudes Spatiales), and EUMETSAT (the European Organization for the Exploitation of Meteorological Satellites).

Launch Timeline

About 154 seconds (just over two minutes) after the Falcon-9 rocket lifts off, the main engine will cut off. About three seconds after that, the rocket's first stage will separate. Second-stage ignition will follow in about eight seconds. Half a minute into the second-stage burn, the payload fairing, or launch vehicle nose cone, will be jettisoned -- a bit over three minutes after launch. The first cutoff of the second-stage engine will take place nine minutes after liftoff.

The Jason-3 spacecraft and second stage will then coast in an intermediate orbit for about another 46 minutes. The second-stage engine will fire a second time about 55 minutes after launch to place Jason-3 in the desired orbit. Separation of the rocket and spacecraft will occur about half a minute later, or almost 56 minutes after liftoff. A little more than two minutes later, Jason-3 will begin to deploy its twin solar arrays to prepare for operation.
