China’s First Mars Exploration Mission Achieves Rich Scientific Results

China’s first Mars exploration mission has achieved rich scientific results, the China National Space Administration (CNSA) announced on September 18.

As of September 15, theTianwen-1orbiter has been operating normally for over 780 days, and the roverZhuronghas traveled 1,921 meters on the surface of Mars. During the period, the orbiter and rover of China’sTianwen-1probe have completed their targeted scientific exploration missions and have acquired 1,480 gigabytes of raw scientific data.

TheTianwen-1probe consists of an orbiter, a lander, and a rover. On May 15, 2021, it touched down at its pre-selected landing area in Utopia Planitia, a vast Martian plain, marking the first time China has landed a probe on the planet.

Chinese researchers have conducted a comprehensive study of typical landforms at the landing area, including concave cones, impact craters, and grooves, and revealed a significant link between the formation of ridges and water activity.

Through camera images and spectral data, researchers found water-bearing minerals in plate-like hard crust rocks near the landing area, which proved that there had been a lot of liquid water activities in the landing area about 1 billion years ago.

Combining camera images with the rover moving rutting and other information, the researchers also found that the soil in the landing area has massive bearing strength and low friction parameters.

These new results reveal the impact of wind and water activities on the geological evolution and environmental changes on Mars. It strongly supports the hypothesis that there was once an ocean on Mars’ Utopia Planitia. It also enriches human scientific understanding of the geological evolution and environmental changes on Mars.

In addition, researchers also used theTianwen-1exploration data to obtain several outstanding scientific achievements, including defining the relationship between rock density on the surface of Mars and surface erosion degrees, and discerning the distribution of ions and neutral particles in the near-Mars space environment, and the gravity field of Mars.

Ember 2 Temperature Control Smart Mug

The smart mug comes with a built-in heater that can maintain the heat of your favorite beverage for up to 1.5 hours on its own. You can even enjoy it all day if you use it together with the redesigned charging coaster. It comes with a LED indicator located just below the base that indicates when your drink is ready, when it is on, and when it is asleep. It goes into sleep mode when it is empty and turns on when it senses movement or contains liquid. The smart mug can also be controlled via a smartphone using the accompanying Ember app in order to customize presets, set the desired temperature as well as send notifications to you via smartphone if your drink is ready.

PrinCube Mobile Color Printer

People can use the PrinCube Mobile Color Printer for documents, T-shirt printing, label creation, and a lot more. This printer makes use of three-color thermal ink-jet technology to provide vivid color prints on virtually any type of surface. It works together with smartphones in doing printing jobs on the go. It can also work over Wi-Fi connections to send out files for printing. Users only need to slide the portable printer over a surface and it prints out along the way.

Samsung Ballie

The new Samsung Ballie comes with advanced AI technology that gives it the ability to act on its own. It recognizes its owner and can follow them wherever he or she goes. It also gives people that little personal space they want and does not intrude too much, unless commanded to. It can interact with the other smart gadgets within your home, and act as both the caretaker and the security personnel of a modern smart home. It is basically that smart assistant that you may want to have around.
