James Webb Space Telescope releases a teaser image, revealing a deep universe

Posted by in categories: engineering, space

Scientists begin the countdown to July 12 date with Webb images. Launched in December 2021, the James Webb Space Telescope, the observatory, is all set to ensure it is ready for science.

Webb’s Fine Guidance Sensor (FGS) recently captured a view of stars and galaxies that provides a tantalizing glimpse at what the telescope’s science instruments will reveal in the coming weeks, months, and years.

The resulting engineering test image is among the deepest images of the universe ever taken, representing highly faint objects, and is now the deepest image of the infrared sky. Bright stars stand out with their six long, sharply defined diffraction spikes. This was the effect of Webb’s six-sided mirror segments. Beyond the stars – galaxies fill nearly the entire background.

China Rejects NASA’s Claim That It Plans to ‘Take Over’ the Moon

Posted by in categories: military, space

NASA director Bill Nelson warned that China’s space program was primarily established to be used as an extension of its military rather than for peaceful or scientific purposes.

By Trevor Filseth L

China’s Foreign Ministry issued a condemnation on Monday of reports from the United States that Beijing intends to pursue exclusive control over the Moon in the future, accusing administrators within the U.S. National Aeronautics and Space Administration (NASA) of ignoring facts and speaking “irresponsibly” about China’s space program.

Space Force Launches New Intelligence Unit as Congress Voices Concerns over Growth

Posted by in categories: government, military, space

The Space Force has assumed command of a new unit that will be focused on keeping an eye out for foreign threats in space, but it comes as Congress is warning the small service branch that it has to prepare to slow its growth.

Delta 18 and the brand-new National Space Intelligence Center were officially commissioned late last month at Wright-Patterson Air Force Base in Dayton, Ohio. It will be staffed by nearly 350 civilian and military personnel.

Delta 18’s mission is to “deliver critical intelligence on threat systems, foreign intentions, and activities in the space domain to support national leaders, allies, partners and joint war fighters,” according to a press release.

NASA Reveals Surface of Asteroid Bennu is Like Plastic Ball Pit

Posted by in category: space

After analyzing data gathered when NASA’s OSIRIS-REx spacecraft collected a sample from asteroid Bennu in October 2020, scientists have learned something astonishing.


Analyses of seismic waves picked up by NASA’s InSight lander shed new light on the planet’s core and give clues to the thickness of the crust.

Marsquakes reveal the Red Planet boasts a liquid core half its diameter

Posted by in categories: materials, space

Mars has had its first CT scan, thanks to analyses of seismic waves picked up by NASA’s InSight lander. Diagnosis: The Red Planet’s core is at least partially liquid, as some previous studies had suggested, and is somewhat larger than expected.

InSight reached Mars in late 2018 and soon afterward detected the first known marsquake (SN: 11/26/18; SN: 4/23/19). Since then, the lander’s instruments have picked up more than a thousand temblors, most of them minor rumbles. Many of those quakes originated at a seismically active region more than 1,000 kilometers away from the lander. A small fraction of the quakes had magnitudes ranging from 3.0 to 4.0, and the resulting vibrations have enabled scientists to probe Mars and reveal new clues about its inner structure.

Simon Stähler, a seismologist at ETH Zurich, and colleagues analyzed seismic waves from 11 marsquakes, looking for two types of waves: pressure and shear. Unlike pressure waves, shear waves can’t pass through a liquid, and they move more slowly, traveling side to side through solid materials, rather than in a push-and-pull motion in the same direction a wave is traveling like pressure waves do.
