NASA Invites Media to Witness World’s First Planetary Defense Test
Tuesday, 23 August 2022 14:38
NASA’s Double Asteroid Redirection Test (DART), the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards, will impact its target asteroid—which poses no threat to Earth—at 7:14 p.m. EDT on Monday, Sept. 26. Saturn V was loud but didn't melt concrete

The Saturn V carried man to the moon and remains the most powerful rocket to successfully launch to orbit. It captures the imagination—but sometimes, it might capture a bit too much imagination. Abundant internet claims about the acoustic power of the rocket suggest that it melted concrete and lit grass on fire over a mile away.
Such ideas are undeniably false. In The Journal of the Acoustical Society of America, researchers from Brigham Young University used a physics-based model to estimate the acoustic levels of the Saturn V. They obtained a value of 203 decibels, which matched the very limited data from the 1960s.
To put that number into perspective, commercial jet engines range from around 120 to 160 decibels.
"Decibels are logarithmic, so every 10 decibels is an order of magnitude increase," said author Kent L.

While concepts for space-based solar power plants have been around for decades, the economics have not added up. That could be changing with the advent of renewable rockets and advancing in-orbit assembly capabilities.

At a time when astronomers around the world are reveling in new views of the distant cosmos, an experiment on the International Space Station has given Cornell researchers fresh insight into something a little closer to home: water.
Specifically, the space station's microgravity environment illuminated the ways that water droplets oscillate and spread across solid surfaces - knowledge that US Navy military sealift command awards Inmarsat 10-year wideband follow-on contract

Until now, it has been assumed that the oxygenation of the oceans over geological timescales has mainly been driven by atmospheric oxygen levels. However, a new study published in Nature on June 27 2022 suggests otherwise.

Numerous software tools are typically required throughout a space mission; from the mission conceptualization and satellite design, to testing the hardware, to running operations. Still today, this technology stack consists of independent systems that don't talk to each other, requiring manual movement of data, limiting automation and forcing engineering teams to work with different data sets. Webb's Jupiter images showcase auroras, hazes
Tuesday, 23 August 2022 10:58
With giant storms, powerful winds, auroras, and extreme temperature and pressure conditions, Jupiter has a lot going on. Now, NASA's James Webb Space Telescope has captured new images of the planet. Webb's Jupiter observations will give scientists even more clues to Jupiter's inner life.

After an extended stay at "Wildcat Ridge," the Perseverance team is preparing to head southwest to another sedimentary outcrop on the Jezero Crater delta called Enchanted Lake. This site has enchanted our science team since we first visited it back April.
The drive to "Enchanted Lake" is expected to begin in the next few days with arrival in early September.

The latest images of Jupiter from the James Webb Space Telescope (JWST) are stunners. Captured on July 27, the infrared images - artificially colored to make specific features stand out - show fine filigree along the edges of the colored bands and around the Great Red Spot and also provide an unprecedented view of the auroras over the north and south poles.

Imagine you go to a theme park with your family and you ask a park employee to take a group photo. A celebrity walks by in the background and waves at the camera, stealing the focus of the photo. Surprisingly, this concept of "photobombing" is relevant to astronomers looking for habitable planets, too.

The harder you hit something - a ball, a walnut, a geode - the more likely it is to break open. Or, if not break open, at least lose a little bit of its structural integrity, the way baseball players pummel new gloves to make them softer and more flexible. Cracks, massive or tiny, form and bear a silent, permanent witness to the impact.
