Vibration tests for Moon rocket help ensure safe travels on road to space
Friday, 20 August 2021 08:30
Driving down a bumpy gravel road, even an off-road vehicle experiences bumps and vibrations, partly because of the car's natural frequency. An object's natural frequency is the frequency or rate that it vibrates naturally when struck. When forces like speed and the smoothness of the road are just right, the car will vibrate in tune with that same frequency.

Two astronauts will venture outside the International Space Station Tuesday, Aug. 24, for a spacewalk to install a support bracket in preparation for future installation of the orbiting laboratory's third new solar array.
NASA will discuss the upcoming spacewalk during a news conference at 2 p.m. EDT Monday, Aug. 23. Live coverage of the news conference and spacewalk will air on NASA Telev Construction begins on NOIRLab Windows on the Universe Center

What was once the largest solar observatory in the world is now undergoing a transformation to become a one-of-a-kind facility for sharing the wonders of astronomy with people around the globe. Construction work has started to recast the McMath-Pierce Solar Telescope facility at Kitt Peak National Observatory into the NOIRLab Windows on the Universe Center for Astronomy Outreach.
Dedicated Researchers from IRSOL and IAC solve twenty-year-old paradox in solar physics
Friday, 20 August 2021 08:30
In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been recently discovered analysing the polarization of sunlight, implies that the solar chromosphere (a very important layer of the solar atmosphere) is practically unmagnetised, in sharp contradiction with common wisdom. This paradox motivated laboratory experiments and theoretical investigatio Scientists detect never-before-seen radio waves from nearby stars and distant galaxies

Scientists have measured thousands of nearby stars and far away galaxies that have never been identified before at radio wavelengths, while studying a galactic body that neighbours our own Milky Way galaxy - the Large Magellanic Cloud.

Advanced military platforms, ocean-bottom survey systems and remote sensing applications all require precise timing for mission success. Chip Scale Atomic Clocks (CSACs) ensure stable and accurate timing even when Global Navigation Satellite Systems (GNSS) time signals are unavailable. Helping industrial and military system designers to meet this requirement, Microchip Technology Inc. has announ NASA watches water to help grow our groceries

Every day - up to thirty times a day, in fact - one of Mark Mason's employees at Nature's Reward Farms in Monterey County, California brings him the results of a soil test for discussion.
Mason supervises fertilizer and irrigation for the farm's 5,000 acres along California's Central Coast, which is nicknamed "America's Salad Bowl" and is one of the most productive and diverse agricultural FSU researchers refine estimate of amount of carbon in Earth's outer core
Friday, 20 August 2021 08:30
New research from Florida State University and Rice University is providing a better estimate of the amount of carbon in the Earth's outer core, and the work suggests the core could be the planet's largest reservoir of that element.
The research, published in the journal Communications Earth and Environment, estimates that 0.3 to 2.0 percent of the Earth's outer core is carbon.
Thoug Greenland, Antarctica will respond differently to increased future warming
Friday, 20 August 2021 08:30
The recently released IPCC Sixth Assessment Report predicts faster warming of Earth's atmosphere and oceans compared to previous assessments. Now, new research shows how the new generation of climate models used in the assessment differ from earlier models in their prediction of the impact on the Antarctic and Greenland ice sheets on sea level rise.

After four months of darkness, it is finally time to rise and shine for the crew at Concordia Research Station in Antarctica. The most-welcome Sun finally made its appearance on 11 August and ESA-sponsored medical doctor Nick Smith was not about to miss it.
For nine months Nick and his fellow crew mates have been living and working in one of the most isolated, confined and extreme environments on Earth, with no way in or out of the Station during the winter-over period.
Nick is overseeing experiments in human physiology and biology, atmospheric physics, meteorology, and astronomy, among other disciplines.
Astronauts conduct second Chinese space station spacewalk

Two Chinese astronauts embarked on a second Shenzhou-12 spacewalk late Thursday to carry out work on a space station robotic arm.
China's astronauts make spacewalk to upgrade robotic arm
Friday, 20 August 2021 06:01
Chinese astronauts edged into space on Friday to add the finishing touches to a robotic arm on the Tiangong space station.
The foray, the second spacewalk in two months and relayed on state television, is part of China's heavily promoted space programme which has already seen the nation land a rover on Mars and send probes to the moon.
In June, three crew arrived at the station, where they are set to remain in space for a total of three months in China's longest crewed mission to date.
Blue Origin suit stops work on NASA HLS contract with SpaceX

NASA will stop work on a Human Landing System award to SpaceX through the end of October as a federal court takes up a suit filed by Blue Origin protesting the contract.
Netflix announces documentary series on Inspiration4 space mission
Thursday, 19 August 2021 19:52
Netflix will soon premiere a documentary series chronicling Inspiration4, the world's first all-civilian space mission, the streaming service said Thursday.
The five-episode show will air in September and will depict how the four-member crew is preparing and then launching into space aboard a SpaceX Falcon 9 rocket, in near real time.
The mission, scheduled for September 15, is financed and run by Jared Isaacman, the 38-year-old founder of payment processing company Shift4 Payments and the latest wealthy businessman to take advantage of the growing space tourism industry.
Isaacman has invited three "everyday" people along with him for the ride: a medical worker, a college professor and an engineer.
The show, titled "Countdown: Inspiration4 Mission To Space" will "take viewers behind the scenes with the four crew members—from their unconventional selection and intensive months-long commercial astronaut training, through the intimate and emotional moments leading up to liftoff," Netflix said in a statement.
