The only picture ever taken of Concorde flying at Mach 2 (1,350 mph). Taken by Adrian Meredith from an RAF Tornado fighter jet, which only rendezvoused with Concorde for 4 minutes over the Irish Sea: The Tornado was rapidly running out of fuel, struggling to keep up with Concorde at Mach 2.

Instruments aboard NASA’s InSight lander are now gathering meteorological data from the Martian surface, allowing for daily weather reports that are being made available to the public.

The daily weather reports from Elysium Planitia began on February 11, and contain information about air temperature, wind speed, and air pressure, reports NASA.

A NASA camera aboard the Deep Space Climate Observatory (DSCOVR) satellite captured a unique view of the moon as it moved in front of the sunlit side of Earth last month. The series of test images shows the fully illuminated ‘dark side’ of the moon that is never visible from Earth. The images were captured by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope on the DSCOVR satellite orbiting 1 million miles from Earth. From its position between the sun and Earth, DSCOVR conducts its primary mission of real-time solar wind monitoring for the National Oceanic and Atmospheric Administration (NOAA). EPIC maintains a constant view of the fully illuminated Earth as it rotates, providing scientific observations of ozone, vegetation, cloud height and aerosols in the atmosphere. Once EPIC begins regular observations next month, the camera will provide a series of Earth images allowing study of daily variations over the entire globe. About twice a year the camera will capture the moon and Earth together as the orbit of DSCOVR crosses the orbital plane of the moon. These images were taken between 12:50 p.m. and 5:45 p.m. PDT on July 16, showing the moon moving over the Pacific Ocean near North America. The North Pole is in the upper left corner of the image, reflecting the orbital tilt of Earth from the vantage point of the spacecraft. EPIC’s ‘natural color’ images of Earth are generated by combining three separate monochrome exposures taken by the camera in quick succession. EPIC takes a series of 10 images using different narrowband spectral filters — from ultraviolet to near infrared — to produce a variety of science products. The red, green and blue channel images are used in these color images. Combining three images taken about 30 seconds apart as the moon moves produces a slight but noticeable camera artifact on the right side of the moon. Because the moon has moved in relation to the Earth between the time the first (red) and last (green) exposures were made, a thin green offset appears on the right side of the moon when the three exposures are combined. This natural lunar movement also produces a slight red and blue offset on the left side of the moon in these unaltered images. The lunar far side lacks the large, dark, basaltic plains, or maria, that are so prominent on the Earth-facing side. The largest far side features are Mare Moscoviense in the upper left and Tsiolkovskiy crater in the lower left. A thin sliver of shadowed area of moon is visible on its right side.

One way to crack this problem, according to the authors of a Perspective in this issue, is through a hybrid approach. The latest techniques in deep learning should be accompanied by a hand-in-glove pursuit of conventional physical modelling to help to overcome otherwise intractable problems such as simulating the particle-formation processes that govern cloud convection. The hybrid approach makes the most of well-understood physical principles such as fluid dynamics, incorporating deep learning where physical processes cannot yet be adequately resolved.

Studies of complex climate and ocean systems could gain from a hybrid between artificial intelligence and physical modelling.

The Salt Honey bees deal with many stressors: chemicals, climate change and viruses. But this year, a tiny mite has wiped out colonies, causing worry over whether there are enough bees left to do their jobs.

An ambitious new analysis of the world’s forests found that there’s space to plant 1.2 trillion new trees — a number that would absorb more carbon than human emissions.

According to the new data, ETH Zurich researcher Thomas Crowther told The Independent, trees are “our most powerful weapon in the fight against climate change.”

Crowther told The Independent that the new analysis, which he presented at a conference this weekend, suggests that a worldwide tree-planting spree would have a greater impact on the planet’s environment than building wind turbines or vegetarian diets — an effort, he says, that could cancel a decade of greenhouse emissions.

When “liking” your favorite tweet isn’t enough, you can now send small bitcoin transactions.

Announced Saturday, the beta app Tippin has released a new Chrome Extension available to Google browser users. Over Twitter, app users can send bitcoin payments via the Lightning Network, considered a way to make bitcoin transactions feasible at a large scale for the first time.

With the extension enabled, a little lightning bolt symbol pops up inside every tweet next to the more familiar “like” and “retweet” buttons.

Officials in Tokyo are testing a new technology that utilizes weather radar and terrestrial digital radio waves to “quickly and precisely predict torrential rain and tornadoes” up to 20 to 30 minutes in advance, the Mainichi reported on Sunday.

The new technology is being developed by “industry, government and academic bodies including the National Institute of Information and Communications Technology (NICT)” based in Koganei, the Mainichi wrote, and is hoped to be ready for deployment ahead of the 2020 Tokyo Olympics and Paralympics. Existing radar systems are limited in their ability to predict “guerilla rainstorms,” so called because they form quickly from rising, cooling water vapor and strike with little warning in specific areas. However, the new system is much more powerful and capable of estimating the size of raindrops and the structure of clouds, the Mainichi wrote:

Developers say the new “multi parameter phased array weather radar” (MP-PAWR) being tested can predict torrential downpours and tornadoes 20 to 30 minutes before they occur. This is because it has a flat antenna that emits radio waves over a wider range than the rotating bowl-shaped antennas used in traditional radars. It is a combination of an MP radar that enables observation of the size of raindrops, and a phased array radar that provides 3D scans of the structure of clouds in about 30 seconds.

Unlike high tech solutions to climate change like carbon capture systems, Crowther argued, trees are nice because anyone can plant one.

“It’s a beautiful thing because everyone can get involved,” he told The Independent. “Trees literally just make people happier in urban environments, they improve air quality, water quality, food quality, ecosystem service, it’s such an easy, tangible thing.”
