This month NASA’s DART spacecraft will collide with the smaller of the two Didymos asteroids in deep space, attempting to shift its orbit in what will be humankind’s first test of the ‘kinetic impactor’ planetary defence technique. Meanwhile, down on the ground, ESA’s follow-on mission to Didymos has reached its own crucial milestone.

Intelsat’s Galaxy 15 mutes payload as it drifts into other satellite paths

Intelsat said the Galaxy 15 broadcast satellite that stopped responding to commands earlier this month shut down its payload Aug. 31, reducing the risk of interfering with signals from other spacecraft.

MOXIE experiment reliably produces oxygen on Mars
Wednesday, 31 August 2022 17:00 Write a comment
On the red and dusty surface of Mars, nearly 100 million miles from Earth, an instrument the size of a lunchbox is proving it can reliably do the work of a small tree.
The MIT-led Mars Oxygen In-Situ Resource Utilization Experiment, or MOXIE, has been successfully making oxygen from the Red Planet's carbon-dioxide-rich atmosphere since February 2021, when it touched down on the Martian surface as part of NASA's Perseverance rover mission.
In a study published in the journal Science Advances, researchers report that, by the end of 2021, MOXIE was able to produce oxygen on seven experimental runs, in a variety of atmospheric conditions, including during the day and night, and through different Martian seasons. In each run, the instrument reached its target of producing six grams of oxygen per hour—about the rate of a modest tree on Earth.
Researchers envision that a scaled-up version of MOXIE could be sent to Mars ahead of a human mission, to continuously produce oxygen at the rate of several hundred trees. At that capacity, the system should generate enough oxygen to both sustain humans once they arrive, and fuel a rocket for returning astronauts back to Earth.
Webb's first full-color images, data are set to sound
Wednesday, 31 August 2022 16:35 Write a comment
There's a new, immersive way to explore some of the first full-color infrared images and data from NASA's JWST—through sound. Listeners can enter the complex soundscape of the Cosmic Cliffs in the Carina Nebula, explore the contrasting tones of two images that depict the Southern Ring Nebula, and identify the individual data points in a transmission spectrum of hot gas giant exoplanet WASP-96 b.
A team of scientists—including Kim Arcand of the Center for Astrophysics | Harvard & Smithsonian—musicians, and a member of the blind and visually impaired community worked to adapt JWST's data, with support from the JWST mission and NASA's Universe of Learning.
"Music taps into our emotional centers," says Matt Russo, a musician and physics professor at the University of Toronto. "Our goal is to make Webb's images and data understandable through sound—helping listeners create their own mental images."
These audio tracks support blind and low-vision listeners first, but are designed to be captivating to anyone who tunes in.
"These compositions provide a different way to experience the detailed information in Webb's first data.

Comet impacts formed continents when Solar System entered galactic arms

New Curtin research has found evidence that Earth's early continents resulted from being hit by comets as our Solar System passed into and out of the spiral arms of the Milky Way Galaxy, turning traditional thinking about our planet's formation on its head.

A group of international scientists led by Cornell is - more rigorously and systematically than ever before - evaluating if and how the stratosphere could be made just a little bit "brighter," reflecting more incoming sunlight so that an ever-warming Earth maintains its cool.
Their work was published Aug. 12 in the Proceedings of the National Academy of Sciences.

Solar cells are vital for the green energy transition. They can be used not only on rooftops and solar farms but also for powering autonomous vehicles, such as planes and satellites. However, photovoltaic solar cells are currently heavy and bulky, making them difficult to transport to remote locations off-grid, where they are much needed.
