Watch China’s moon mission touch down on the planet’s far side

By

China’s Chang’e 4 mission to the far side of the moon landed successfully at the start of the month, and now footage has been shared of a lander’s-eye view of the touchdown.

CLEP/CNSA

The Chang’e 4 mission touched down in the 115-mile-wide (185 kilometers) Von Kármán Crater on the far side of the moon on January 2 this year. It captured footage of the descent towards the surface with a camera which was attached to the probe. The black and white video footage of the landing starts off with a view of the lunar landscape, then shows the craft pivoting towards the surface of the Moon at around the one minute mark. The Von Kármán Crater is visible as the craft descends towards the surface.

The craft pauses at around the two minute mark, likely using instruments to assess the surface below and check that it was suitable for landing. Having confirmed that the landing site is good, the craft continues onward and touches down on the surface. You can see the dust and debris which is kicked up by the craft’s descent engines.

Chang'e-4 descent footage

The Chang’e 4 craft contains a lander and a rover which have a range of scientific instruments between them for investigating the surface of the Moon and its subsurface. The hope is that data from this mission could shed light on the structure of the Moon and on how it evolved over time, according to Chinese officials. In addition, a biological experiment is included in the mission. There is a tin containing silkworm eggs and plant seeds to see how these organisms develop in the low-gravity environment, which could be important in the future for growing food in space, among other things.

This is the first ever mission to successfully touch down on the far side of the moon — the side of the moon which is always facing away from the Earth. This location is challenging to land on because it is usually impossible to communicate between there and Earth due to the the lack of an unobstructed path between the two locations. However, China has overcome this by sending a satellite into orbit around the Moon which collects data from the craft and relays it back to Earth.

BYD’s cheap EVs might remain out of Canada too
BYD Han

With Chinese-made electric vehicles facing stiff tariffs in both Europe and America, a stirring question for EV drivers has started to arise: Can the race to make EVs more affordable continue if the world leader is kept out of the race?

China’s BYD, recognized as a global leader in terms of affordability, had to backtrack on plans to reach the U.S. market after the Biden administration in May imposed 100% tariffs on EVs made in China.

Tesla posts exaggerate self-driving capacity, safety regulators say
Beta of Tesla's FSD in a car.

The National Highway Traffic Safety Administration (NHTSA) is concerned that Tesla’s use of social media and its website makes false promises about the automaker’s full-self driving (FSD) software.
The warning dates back from May, but was made public in an email to Tesla released on November 8.
The NHTSA opened an investigation in October into 2.4 million Tesla vehicles equipped with the FSD software, following three reported collisions and a fatal crash. The investigation centers on FSD’s ability to perform in “relatively common” reduced visibility conditions, such as sun glare, fog, and airborne dust.
In these instances, it appears that “the driver may not be aware that he or she is responsible” to make appropriate operational selections, or “fully understand” the nuances of the system, NHTSA said.
Meanwhile, “Tesla’s X (Twitter) account has reposted or endorsed postings that exhibit disengaged driver behavior,” Gregory Magno, the NHTSA’s vehicle defects chief investigator, wrote to Tesla in an email.
The postings, which included reposted YouTube videos, may encourage viewers to see FSD-supervised as a “Robotaxi” instead of a partially automated, driver-assist system that requires “persistent attention and intermittent intervention by the driver,” Magno said.
In one of a number of Tesla posts on X, the social media platform owned by Tesla CEO Elon Musk, a driver was seen using FSD to reach a hospital while undergoing a heart attack. In another post, a driver said he had used FSD for a 50-minute ride home. Meanwhile, third-party comments on the posts promoted the advantages of using FSD while under the influence of alcohol or when tired, NHTSA said.
Tesla’s official website also promotes conflicting messaging on the capabilities of the FSD software, the regulator said.
NHTSA has requested that Tesla revisit its communications to ensure its messaging remains consistent with FSD’s approved instructions, namely that the software provides only a driver assist/support system requiring drivers to remain vigilant and maintain constant readiness to intervene in driving.
Tesla last month unveiled the Cybercab, an autonomous-driving EV with no steering wheel or pedals. The vehicle has been promoted as a robotaxi, a self-driving vehicle operated as part of a ride-paying service, such as the one already offered by Alphabet-owned Waymo.
But Tesla’s self-driving technology has remained under the scrutiny of regulators. FSD relies on multiple onboard cameras to feed machine-learning models that, in turn, help the car make decisions based on what it sees.
Meanwhile, Waymo’s technology relies on premapped roads, sensors, cameras, radar, and lidar (a laser-light radar), which might be very costly, but has met the approval of safety regulators.

Waymo, Nexar present AI-based study to protect ‘vulnerable’ road users
waymo data vulnerable road users ml still 1 ea18c3

Robotaxi operator Waymo says its partnership with Nexar, a machine-learning tech firm dedicated to improving road safety, has yielded the largest dataset of its kind in the U.S., which will help inform the driving of its own automated vehicles.

As part of its latest research with Nexar, Waymo has reconstructed hundreds of crashes involving what it calls ‘vulnerable road users’ (VRUs), such as pedestrians walking through crosswalks, biyclists in city streets, or high-speed motorcycle riders on highways.
