Webb Telescope Parts Arrive In California
Febuary 6, 2018 – The two halves of NASA’s James Webb Space Telescope now reside at Northrop Grumman Aerospace Systems in Redondo Beach, California, where they will come together to form the complete observatory. Webb’s optical telescope and integrated science instrument module (OTIS) arrived at Northrop Grumman February 2, from NASA’s Johnson Space Center in Houston, where it successfully completed cryogenic testing.

February 6, 2018 – In this view, Saturn’s icy moon Rhea passes in front of Titan as seen by NASA’s Cassini spacecraft. Some of the differences between the two large moons are readily apparent. While Rhea is a heavily-cratered, airless world, Titan’s nitrogen-rich atmosphere is even thicker than Earth’s. Read More

Cassini’s Grand Finale
In this public lecture on February 7, Larry Esposito will talk about NASA’s Cassini orbiter, which ended its 13-year exploration of the Saturn system on September 15, 2017, burning up in the planet’s atmosphere as planned. LASP designed, built, tested, and operated Cassini’s UltraViolet Imaging Spectrograph (UVIS). Even though the mission has ended, team members worldwide will continue to interpret instrument observations and publish results in scientific journals for years to come.
Two Small Asteroids Safely Pass Earth This Week
Two small asteroids recently discovered by astronomers at the NASA-funded Catalina Sky Survey (CSS) near Tucson, Arizona, are safely passing by Earth within one lunar distance this week.
NASA Tests Atomic Clock For Deep Space Navigation
In deep space, accurate timekeeping is vital to navigation, but not all spacecraft have precise timepieces aboard. For 20 years, NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, has been perfecting a clock. It’s not a wristwatch; not something available in a store. It’s the Deep Space Atomic Clock (DSAC), an instrument being built for deep space exploration.
ESA’s first mission of the year was launched: GomX-4B is the Agency’s most advanced technology-tester yet, featuring a hyperspectral camera and tiny thrusters to manoeuvre thousands of kilometres from its near-twin to try out their radio link.
Researchers have discovered permafrost in the northern hemisphere stores massive amounts of natural mercury, a finding with significant implications for human health and ecosystems worldwide. In a new study, scientists measured mercury concentrations in permafrost cores from Alaska and estimated how much mercury has been trapped in permafrost north of the equator since the last Ice Age.
NASA Tech Aims To Track Tomorrow’s Supersonic Airliners

NASA plans two flight tests this year of an enhanced ADS-B radio-and-GPS device that could help a new generation of supersonic commercial jets meet an FAA mandate that will soon be imposed on aircraft in most controlled airspace.
Executive Mosaic is pleased to introduce Rick Ambrose, executive vice president of Lockheed Martin’s space systems segment, as an inductee into the 2018 edition of the Wash100 — Executive Mosaic’s annual selection of influential leaders in the government contracting arena–for his executive project management of innovations in improving intelligence technology initiatives.
Observations From -369.7 Degrees Fahrenheit
Taken from inside Chamber A at the Johnson Space Center in Houston in September 2017 while the combined optical and science instrument element of the James Webb Space Telescope was undergoing cryogenic testing, the temperature at the time this image was taken was approximately 50 kelvins (about -369.7 degrees Fahrenheit/-223.2 degrees Celsius). The camera that captured this image was placed inside the chamber to measure the telescope’s alignment, but engineers also used it to monitor the black DuPont™ Kapton® covering that outlines Webb’s primary mirror. Engineers used this and other images to assess the material’s slack as the telescope shrank ever so slightly in the extreme cold of the chamber.
NASA iTech has selected the top three teams out of a group of 10 finalists for their innovative technology projects and ideas that may improve future deep space exploration and life on Earth. NASA iTech is a collaborative effort to find and foster innovative solutions that aim to solve problems on Earth, and also advance technologies necessary to achieve NASA’s strategic objectives. The winning teams of entrepreneurs presented their proposed solutions to tough space technology challenges and were evaluated by NASA’s chief technologists, space industry leaders and potential investors.
Where No Mission Has Gone Before
Living near a star is risky business, and positioning a spacecraft near the Sun is a very good way to observe rapidly changing solar activity and deliver early warning of possibly harmful space weather. ESA is now looking at doing just that.
NanoRacks announced today that Thales Alenia Space, the joint venture between Thales (67%) and Leonardo (33%), has been chosen as the latest partner in its commercial airlock program. Thales Alenia Space will produce and test the critical pressure shell for NanoRacks’ Airlock Module, which is targeting to be launched to the International Space Station late 2019, and will be used to deploy commercial and government payloads.
The maiden flight of SpaceX’s Falcon Heavy booster, slated to launch tomorrow (Feb. 6), comes factory-equipped with a Tesla Roadster as a part of the payload/ballast, and is meant to be hurled toward a solar orbit that could take it as far out as the orbit of Mars. But what’s the point of sending a car into space? Is it bound to become just more space junk?
New Studies Of Clay Formation Provide Clues About Early Martian Climate
Source: SETI Institute
The climate on early Mars has presented an enigma for planetary scientists because surface features such as valley networks indicate abundant liquid water was present and the clay minerals found in most ancient surface rocks need even warmer temperatures to form, while atmospheric models generally support a cold climate on early Mars. This new study led by Janice Bishop of the SETI Institute and NASA’s Ames Research Center in Silicon Valley has addressed this question by investigating the conditions needed for the formation of the ancient surface clays.
LISA Pathfinder — The Quietest Place In Space
Source: Max Planck Institute for Gravitational Physics
The final results from the ESA satellite LISA Pathfinder (LPF) have been published today. Using data taken before the end of the mission in July 2017, the LPF team – including researchers from the Max Planck Institute for Gravitational Physics in Hannover and Leibniz Universität Hannover – significantly improved first results published in mid 2016. LPF now has exceeded the requirements for key technologies for LISA, the future gravitational-wave observatory in space, by more than a factor of two over the entire observation band. LISA is scheduled to launch into space in 2034 as an ESA mission and will “listen” to low-frequency gravitational waves from merging supermassive black holes in the entire Universe and tens of thousands of binary stars in our Galaxy.
Why is the Arctic warming faster than the rest of the planet? Does mineral dust warm or cool the atmosphere? NASA has selected two new, creative research proposals to develop small, space-based instruments that will tackle these fundamental questions about our home planet and its environment.
