After several assists from InSight Lander’s arm, the mole appears to be underground. It’s been a real challenge troubleshooting for NASA & DLR from millions of miles away. We still need to see if the mole can dig on its own. There was no way to predict the duracrust and what it meant for the Mole. The future is still uncertain.
Researchers using a technique known as “lucky imaging” with the Gemini North telescope on Hawaii’s Maunakea have collected some of the highest resolution images of Jupiter ever obtained from the ground. These images are part of a multi-year joint observing program with the Hubble Space Telescope in support of NASA’s Juno mission. The Gemini images, when combined with the Hubble and Juno observations, reveal that lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. The new observations also confirm that dark spots in the famous Great Red Spot are actually gaps in the cloud cover and not due to cloud colour variations.
Hydraulic fracturing, Also Known As Fracking, is a Well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of ‘fracking fluid’ (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures op
It’s a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels. While the asteroid which helped wipe out the dinosaurs blocked out 90% of the Sun’s rays, we would need to divert just 2-4%, it’s believed, to take the Earth back to its pre-industrial climate.
This animation shows a rotating globe of the new Unified Geologic Map of the Moon with shaded topography from the Lunar Orbiter Laser Altimeter (LOLA). This geologic map is a synthesis of six Apollo-era regional geologic maps, updated based on data from recent satellite missions. It will serve as a reference for lunar science and future human missions to the Moon. Credit: NASA/GSFC/USGS.
A four-week-old human embryo already has miles of blood vessels. By adulthood, we each have 60,000 miles of blood vessels inside our bodies – that’s more than twice the distance around the world. Those vessels keep blood flowing, supplying your tissues with oxygen and nutrients and keeping your organs, including the heart, healthy. In the … Read more
Cella and tissues are far from being mere static structures. They have the ability to sense and dynamically react to external cues to ensure that they adapt to the ever-changing outside environment. Now, researchers from the University of Tsukuba have identified a novel protein that plays a central role in the transduction of external mechanical … Read more
