China's LandSpace launches improved methane-powered rocket
BEIJING: A new methane-powered rocket developed by China's LandSpace Technology launched six satellites into orbit on Saturday, as the private startup doubles down on a cheap, cleaner fuel that it hopes will help it develop reusable rockets.
The Zhuque-2E Y2 carrier rocket blasted off at 12:12 p.m. (0412 GMT) from the Jiuquan Satellite Launch Center in northwest China, marking the fifth flight for the Zhuque-2 series, according to a company statement.
Beijing-based LandSpace became the world's first company to launch a methane-liquid oxygen rocket in July 2023, ahead of US rivals including Elon Musk's SpaceX and Jeff Bezos' Blue Origin.
Interest has grown in recent years in launching carrier vehicles fuelled by methane, which is deemed less polluting, safer and cheaper than more commonly used hydrocarbon fuels, and a suitable propellant in a reusable rocket.
LandSpace has increased the rocket's payload, reflecting increasing demand in China's expanding commercial space industry amid growing competition to form a constellation of satellites as an alternative to Musk's Starlink.
Its first successful methane-powered launch did not carry any real satellites, but the second launch in December 2023 successfully sent into orbit three satellites. Saturday's launch put six satellites into orbit, mainly developed by Chinese firm Spacety, also known as Changsha Tianyi Space Science and Technology Research Institute.
Li Xiaoming, the institute's vice-president, said in a livestream hosted by LandSpace before the launch that the payload comprised a radar satellite, two multispectral satellites and three satellites for scientific experiments, weighing between 20 kg and 300 kg (44-660 pounds).
The three research-focussed satellites will help with China's deep-space exploration ambitions, while the pair of multispectral satellites will be dedicated to environmental monitoring and identifying mineral deposits, respectively, Li said.
The radar satellite is an all-weather Earth-observation satellite that produces images during the day and night, as well as see through clouds and rain, he added.
The radar satellite 'can also pick up small, millimetre-level shifts in the surface, a capability that makes it extremely useful across urban development, transportation and energy infrastructure monitoring,' said Li.
Spacety was sanctioned by the US Treasury Department in January 2023 for allegedly supplying a Russian company with radar satellite imagery over Ukraine, which the US said was used to enable the Russian mercenary group Wagner's combat operations in Ukraine.

Musk says Tesla launching robotaxis today in Austin
AUSTIN: After driverless Tesla Model Ys were spotted traversing Austin, Texas streets on Sunday morning, CEO Elon Musk posted on his social platform X that Tesla's "robotaxi launch" would start this afternoon with rides for a flat fee of $4.20. A Reuters witness saw several Tesla "robotaxis" on Sunday morning in a popular area of the Texas capital called South Congress with no one in the driver's seat but one person in the passenger seat. Tesla planned to have front-seat riders acting as "safety monitors," though it remained unclear how much control they would have over the vehicles. Videos of driverless Teslas have also been posted on social media but it was not known if the vehicles carried any passengers. Tesla's public robotaxi rides set for tentative June 22 start, CEO Musk says As the date of the planned robotaxi launch approached, Texas lawmakers moved to enact rules on autonomous vehicles in the state. Texas Governor Greg Abbott, a Republican, on Friday signed legislation requiring a state permit to operate self-driving vehicles. The law does not take effect until September 1, but the governor's approval of it on Friday signals state officials from both parties want the driverless-vehicle industry to proceed cautiously. A group of Democratic state lawmakers earlier this week asked Tesla to delay its planned robotaxi trial because of the legislation. Tesla did not respond to requests for comment. The governor's office declined to comment. The law softens the state's previous anti-regulation stance on autonomous vehicles. A 2017 Texas law specifically prohibited cities from regulating self-driving cars. In recent days, Tesla has sent invites to a select group of Tesla online influencers for a small and carefully monitored robotaxi trial, which the company has said would include 10 or 20 Model Y vehicles operated in a limited zone of Austin. The law requires autonomous-vehicle operators to get approval from the Texas Department of Motor Vehicles before operating on public streets without a human driver. It also gives state authorities the power to revoke permits if they deem a driverless vehicle "endangers the public," and requires firms to provide information on how police and first responders can deal with their driverless vehicles in emergency situations. The law's requirements for getting a state permit to operate an "automated motor vehicle" are not particularly onerous but require a firm to attest it can safely operate within the law. It defines an automated vehicle as having at least "Level 4" autonomous-driving capability under a recognized standard, meaning it can drive itself with no human driver under specified conditions, such as within a limited area. Level 5 autonomy is the top level and means a car can drive itself anywhere, under any conditions. Compliance remains far easier than in some states, most notably California, which requires extensive submission of vehicle-testing data under state oversight. MUSK'S SAFETY PLEDGES The Tesla robotaxi launch, which the company warned might be delayed, comes after more than a decade of CEO Elon Musk's unfulfilled promises to deliver self-driving Teslas. Most of Tesla's sky-high stock value now rests on its ability to deliver robotaxis and humanoid robots, according to many industry analysts. Tesla is by far the world's most valuable automaker. Musk has said Tesla would be "super paranoid" about safety for the Austin rollout. The company planned to operate only in areas it considered the safest. The service in Austin will have other restrictions as well. Tesla plans to avoid bad weather, difficult intersections, and will not carry anyone below the age of 18. Musk has said he is ready to delay the start for safety reasons, if needed. The planned launch has generated buzz among Tesla fans. "Wow. We are going to ride in driverless Teslas in just a few days. On public roads," posted Omar Qazi, who has 635,200 followers on X, writes often about Tesla using the handle @WholeMarsBlog, and received an invite. Commercializing autonomous vehicles has been risky and expensive. GM's Cruise was shut down after a fatal accident and regulators are closely watching Tesla and its rivals, Alphabet's Waymo, which runs a paid robotaxi service in several U.S. cities, and Amazon's Zoox. Tesla is also bucking the young industry's standard practice of relying on multiple technologies to read the road, using only cameras. That, Musk says, will be safe and much less expensive than lidar and radar systems added by rivals.

Florida surgeon performs remote prostate cancer surgery using robotic technology across 7,000 miles
A Florida-based surgeon has made medical history by remotely performing cancer surgery on a patient located over 7,000 miles away in Angola, Africa. The procedure was the first transcontinental robotic telesurgery conducted under a U.S. Food and Drug Administration (FDA) clinical trial. The patient, a 67-year-old man diagnosed with prostate cancer in March, underwent a prostatectomy — a surgery to remove all or part of the prostate, often used to treat prostate cancer and improve survival outcomes. Increasingly, these procedures are carried out using robotic systems due to their precision and reduced recovery times. Although robotic-assisted surgeries are now common, this was the first time such a procedure was performed remotely across continents. Dr. Vipul Patel, medical director of the Global Robotic Institute at Advent Health in Orlando, operated the robot from Florida while the patient remained in Angola, supported by an on-site medical team. Patel and his team had spent two years preparing for the procedure. 'We traveled the globe, looking at the right technologies,' he told ABC News. He emphasized that contingency plans were in place and a full team was stationed with the patient. 'We made sure we had plan A, B, C, and D. I always have my team where the patient is,' he said. The surgery went smoothly, without complications. Patel now plans to submit clinical data from the operation to the FDA in hopes of conducting similar procedures in the future. He believes this breakthrough could reshape healthcare delivery. 'Emergency room physicians will have technology that can be remotely accessible to surgeons, maybe even in the ambulance,' Patel said, highlighting the potential for life-saving interventions when hospital access is limited.
