Toxic plant on Ming dynasty-era surgical tools may be world’s oldest chemical evidence of topical anesthetic
Welcome to Edition 8.43 of the Rocket Report! A disclaimer: No one yet fully appreciates the ramifications of Blue Origin's New Glenn rocket explosion Thursday night on its launch pad at Cape Canaveral, Florida. What we know as of this writing is that much of Blue's sole orbital-class launch pad has been destroyed, and the New Glenn rocket will be grounded for an extended period of time. It is too soon for any hot takes, at least until the Sun rises at the Cape on Friday morning. One thing I am sure of is that we will be writing about this event for weeks, months, and years to come.
As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.
Charting China's contribution to space junk. There's a problem with the drastic uptick in Chinese space launches over the last decade. China appears to be ignoring long-established norms about disposing of the upper stages of rockets, Ars reports. These are the parts of the vehicle that separate from the first stage of a rocket and push a satellite or spacecraft into orbit. In the early decades of spaceflight, launch operators routinely left upper stages in orbit after they released their payloads. But most launch companies today reserve enough propellant in their rockets to remove them from orbit to avoid the risk of spent upper stages becoming a source of space debris. But China is not following this trend. There has been striking growth in China’s rocket body mass. In the past five years, the mass of Chinese rocket bodies in long-lived orbits has risen from less than 100 metric tons to 252, according to a new analysis by Space Domain Awareness expert Jim Shell.

Up until a decade ago, China had never launched as many as 20 orbital rockets a year. But beginning in 2022, the Asian country launched 64 rockets and last year reached a record total of 93, marking it as the second-most productive space power in the world.
Further growth is anticipated from both the company's state-owned enterprises as well as a rapidly expanding number of private launch companies. There is nothing wrong with this, as China's rapid growth in launch has been mirrored by the United States and, in particular, SpaceX.
However there is an issue with these launches, as China appears to be ignoring long-established norms about disposing of the upper stages of rockets. These are the parts of the vehicle that separate from the first stage of a rocket and push a satellite or spacecraft into orbit.

Last month at Beijing’s half marathon, a robot named Lightning beat the human world record by nearly seven minutes. It’s the latest in a string of AI-powered milestones that have got people wondering whether robots are about to enter our everyday lives, just as chatbots have. And the country leading the charge is China, where the government has pledged to invest more than £100bn in robotics over the next 20 years. To find out how robots are already entering the workforce, and what needs to happen to get them cleaning our homes and weeding our gardens, Ian Sample hears from the Guardian’s senior China correspondent, Amy Hawkins, and from Nathan Lepora, professor of robotics and AI at Bristol University, who researches how robots can achieve human-like dexterity
