WALLOPS ISLAND, Va. -- NASA commercial partner Orbital Sciences of Dulles, Va., successfully conducted an engine test of its Antares rocket Friday, February 22, at the nation's newest launch pad.

The company fired dual AJ26 rocket engines for approximately 30 seconds while the first stage of Orbital's Antares rocket was held down on the Mid-Atlantic Regional Spaceport (MARS) Pad-0A at NASA's Wallops Flight Facility in Wallops Island, Va. The test demonstrated the readiness of the rocket's first stage and launch pad fueling systems to support upcoming test flights.

"This pad test is an important reminder of how strong and diverse the commercial space industry is in our nation,” said Phil McAlister, director of Commercial Spaceflight Development at NASA Headquarters in Washington. “A little more than one year after the retirement of the space shuttle, we had a U.S company resupplying the space station, and another is now taking the next critical steps to launch from America’s newest gateway to low-Earth Orbit. Today marks significant progress for Orbital, MARS and the NASA team."

Orbital is building and testing its new rocket and Cygnus cargo spacecraft under NASA's Commercial Orbital Transportation Services (COTS) program. A demonstration flight of Antares and Cygnus to the space station is planned for later this year. Following the successful completion of the COTS demonstration mission to the station, Orbital will begin conducting eight planed cargo resupply flights to the orbiting laboratory through NASA's $1.9 billion Commercial Resupply Services contract with the company.

Wallops, which has launched more than 16,000 rockets in its 67-year history, provided launch range support for the hot fire test, including communications, data collection, range safety and area clearance.

NASA initiatives like COTS are helping develop a robust U.S. commercial space transportation industry with the goal of achieving safe, reliable and cost-effective transportation to and from the space station and low-Earth orbit. In parallel, NASA's Commercial Crew Program is working with commercial space partners developing capabilities to launch U.S. astronauts from U.S. soil in the next few years.

NASA Selects Science Instrument and Hardware for European Mission to Jupiter
 
 
WASHINGTON -- NASA has selected key contributions to a 2022 European Space Agency (ESA) mission that will study Jupiter and three of its largest moons in unprecedented detail. The moons are thought to harbor vast water oceans beneath their icy surfaces.

NASA's contribution will consist of one U.S.-led science instrument and hardware for two European instruments to fly on ESA's Jupiter Icy Moons Explorer (JUICE) mission. JUICE will carry 11 experiments developed by scientific teams from 15 European countries, the United States and Japan.

The spacecraft will orbit Jupiter for three years and travel past its moons Callisto and Europa multiple times, then orbit Ganymede, a moon larger than the planet Mercury. JUICE will conduct the first thorough exploration of Jupiter since NASA's Galileo mission from 1989-2003. By studying the Jupiter system, JUICE will look to learn more about the formation and evolution of potentially habitable worlds in our solar system and beyond.

"NASA is thrilled to collaborate with ESA on this exciting mission to explore Jupiter and its icy moons," said John Grunsfeld, NASA's associate administrator for Science in Washington. "Working together with ESA and our other international partners is key to enabling future scientific progress in our quest to understand the cosmos."

The solar-powered spacecraft will carry cameras and spectrometers, a laser altimeter and an ice-penetrating radar. The mission also will carry a magnetometer, plasma and particle monitors, and radio science hardware. The spacecraft is scheduled to arrive at the Jupiter system in 2030.

"The selection of JUICE's instruments is a key milestone in ESA's flagship mission to the outer solar system, which represents an unprecedented opportunity to showcase leading European technological and scientific expertise," said Alvaro Gimenez Canete, ESA's director of science and robotic exploration.

NASA invited researchers in 2012 to submit proposals for NASA-provided instruments for the mission. Nine were reviewed, with one selected to fly. NASA agreed to provide critical hardware for two of the 10 selected European-led instruments. NASA's total contribution to the JUICE mission is $100 million for design, development, and operation of the instruments through 2033.

The NASA contributions are:

-- Ultraviolet Spectrometer: The principal investigator is Randy Gladstone of Southwest Research Institute in San Antonio. This spectrometer will acquire images to explore the surfaces and atmospheres of Jupiter's icy moons and how they interact with the Jupiter environment. The instrument also will determine how Jupiter's upper atmosphere interacts with its lower atmosphere below, and the ionosphere and magnetosphere above. The instrument will provide images of the aurora on Jupiter and Ganymede.

-- Radar for Icy Moon Exploration: The principal investigator is Lorenzo Bruzzone of Universita degli Studi di Trento in Italy. The U.S. lead is Jeffrey Plaut of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. Under the lead of Bruzzone and the Italian Space Agency, JPL will provide the transmitter and receiver hardware for a radar sounder designed to penetrate the icy crust of Europa, Ganymede, and Callisto to a depth of about 5 miles (9 kilometers). This will allow scientists to see for the first time the underground structure of these tectonically complex and unique icy worlds.

-- Particle Environment Package: The principal investigator is Stas Barabash of the
Swedish Institute of Space Physics. The U.S. lead is Pontus Brandt of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md. Under the lead of Barabash and the Swedish National Space Board, APL will provide instruments to this suite to measure the neutral material and plasma that are accelerated and heated to extreme levels in Jupiter's fierce and complex magnetic environment.
NASA's Science Mission Directorate conducts a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system, and the universe. The New Frontiers Program Office at NASA's Marshall Space Flight Center in Huntsville, Ala., will manage the NASA contributions. JUICE is the first large-class mission in ESA's Cosmic Vision 2015-2025 Program.
