NASA’s Gravity Recovery and Climate Experiment mission coming to a close

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – With one of its twin satellites almost out of fuel after more than 15 years of chasing each other around our planet to measure Earth’s ever-changing gravity field, the operations team for the U.S./German Gravity Recovery and Climate Experiment (GRACE) mission is making plans for an anticipated final science collection.

On September 3rd, one of 20 battery cells aboard the GRACE-2 satellite stopped operating due to an age-related issue. It was the eighth battery cell loss on GRACE-2 since the twin satellites that compose the GRACE mission launched in March 2002 on a mission designed to last five years. The following day, contact was lost with GRACE-2.

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A thrilling epoch in the exploration of our solar system came to a close today, as NASA’s Cassini spacecraft made a fateful plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet.

“This is the final chapter of an amazing mission, but it’s also a new beginning,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at NASA Headquarters in Washington.

NASA’s Cassini Spacecraft begins plunge into Saturn

 

Written by Dwayne Brown / Laurie Cantillo
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Cassini spacecraft is on final approach to Saturn, following confirmation by mission navigators that it is on course to dive into the planet’s atmosphere on Friday, September 15th, 2017.

Cassini is ending its 13-year tour of the Saturn system with an intentional plunge into the planet to ensure Saturn’s moons – in particular Enceladus, with its subsurface ocean and signs of hydrothermal activity – remain pristine for future exploration.

NASA’s Cassini spacecraft makes final flyby of Saturn’s moon Titan

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft is headed toward its September 15th, 2017 plunge into Saturn, following a final, distant flyby of the planet’s giant moon Titan.

The spacecraft made its closest approach to Titan today at 12:04pm PDT (3:04pm EDT), at an altitude of 73,974 miles (119,049 kilometers) above the moon’s surface. The spacecraft is scheduled to make contact with Earth on September 12th at about 6:19pm PDT (9:19pm EDT).

NASA looks back at the accomplishments of the Cassini Spacecraft

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As the Cassini spacecraft nears the end of a long journey rich with scientific and technical accomplishments, it is already having a powerful influence on future exploration. In revealing that Saturn’s moon Enceladus has many of the ingredients needed for life, the mission has inspired a pivot to the exploration of “ocean worlds” that has been sweeping planetary science over the past decade.

“Cassini has transformed our thinking in so many ways, but especially with regard to surprising places in the solar system where life could potentially gain a foothold,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at Headquarters in Washington. “Congratulations to the entire Cassini team!”

How Labor Day Began

 

Labor DayWashington, D.C. – Labor Day is observed the first Monday in September. It is a creation of the labor movement and is dedicated to the social and economic achievements of American workers.

It constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.

Through the years the nation gave increasing emphasis to Labor Day. The first governmental recognition came through municipal ordinances passed during 1885 and 1886.

Written by Guy Webster / Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Preparation of NASA’s next spacecraft to Mars, InSight, has ramped up this summer, on course for launch next May from Vandenberg Air Force Base in central California — the first interplanetary launch in history from America’s West Coast.

Lockheed Martin Space Systems is assembling and testing the InSight spacecraft in a clean room facility near Denver. “Our team resumed system-level integration and test activities last month,” said Stu Spath, spacecraft program manager at Lockheed Martin. “The lander is completed and instruments have been integrated onto it so that we can complete the final spacecraft testing including acoustics, instrument deployments and thermal balance tests.”

NASA picks Six Explorers Program proposals to study our Solar System

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA has selected six astrophysics Explorers Program proposals for concept studies. The proposed missions would study gamma-ray and X-ray emissions from clusters of galaxies and neutron star systems, as well as infrared emissions from galaxies in the early universe and atmospheres of exoplanets, which are planets outside of our solar system.

Three of these proposed missions, called FINESSE, SPHEREx and CASE, are managed by NASA’s Jet Propulsion Laboratory in Pasadena, California. FINESSE and CASE additionally have their principal investigator based at JPL.
