A SpaceX shipment of ants, avocados and a human-sized robotic arm rocketed toward the International Space Station on Sunday.
The delivery — which arrived yesterday — was the company’s 23rd for NASA in just under a decade.

SpaceX founder Elon Musk continued his tradition of naming the booster-recovery vessels in tribute to the late science fiction writer Iain M. Banks and his Culture series.
The Dragon was carrying more than 2,170kg of supplies and experiments, as well as fresh food, including avocados, lemons and even ice cream for the space station’s seven astronauts.
The Girl Scouts are sending up ants, brine shrimp and plants as test subjects, while University of Wisconsin-Madison scientists are flying up seeds from mouse-ear cress, a small flowering weed used in genetic research.
Samples of concrete, solar cells and other materials are also to be subjected to weightlessness.
A Japanese start-up company’s experimental robotic arm is to attempt to screw items together in its orbital debut and perform other mundane chores normally done by astronauts.
The first tests are to be done inside the space station.
Future models of the robot are to venture out into the vacuum of space to practice satellite and other repair jobs, Gitai Inc chief technology officer Toyotaka Kozuki said.
As early as 2025, a squad of the arms could help build lunar bases and mine the moon for precious resources, he said.
SpaceX had to leave some experiments behind because of delays resulting from the COVID-19 pandemic.
It was the second launch attempt; Saturday’s effort was foiled by stormy weather.
NASA turned to SpaceX and other US companies to deliver cargo and crews to the space station when the space shuttle program ended in 2011.
Choosing a full-fledged confrontation with the US due to the loss of a megacontract for submarines for Australia, France is making a risky bet and other nations are not rushing to its defense. After Australia renounced its deal for conventional submarines in favor of US nuclear-powered ones, France took the extraordinary step of pulling its ambassadors from Washington and Canberra for consultations. Bertrand Badie, an international relations professor at the Sciences Po institute in Paris, said France had put itself in a position where it can only appear to be backing down or losing face once its ambassador returns to the US,
Could delivering COVID-19 immunity directly to the nose — the area of the body via which it is mostly transmitted — help conquer the pandemic? The WHO says clinical trials are under way to evaluate eight nasal spray vaccines that target COVID-19. The most advanced effort so far by China’s Xiamen University, the University of Hong Kong and Beijing Wantai Biological Pharmacy has completed phase 2 trials. “When the virus infects someone, it usually gets in through the nose,” said researcher Nathalie Mielcarek, who is working with the Lille Pasteur Institute to develop a nasal spray vaccine against whooping cough. “The
FREE-FOR-ALL CONTEST: Taro Kono’s popular support means that he ‘probably has the edge, but if he has a lead, it’s a very vulnerable one,’ an Asia expert said The campaign to become Japan’s next prime minister began yesterday, with four candidates vying for leadership of the ruling party in an unusually close race. In televised speeches, the candidates set out their priorities, from boosting Japan’s digital prowess to addressing the falling birthrate. Among them are two women hoping to lead a nation that has never had a female prime minister, although both are considered long shots. The race follows Japanese Prime Minister Yoshihide Suga’s shock announcement that he would not run for head of the ruling Liberal Democratic Party (LDP). Whoever the party picks in a Sept. 29 vote is to contest
PLANNING TO REOPEN: Amid 1,607 new COVID-19 cases, the country is making a shift away from lockdowns, acknowledging that outbreaks will happen Australia reported 1,607 new coronavirus cases yesterday as states and territories gradually shift from trying to eliminate outbreaks to living with the virus. Victoria, home to about a quarter of Australia’s 25 million people, recorded 507 cases as Premier Daniel Andrews said a weeks-long lockdown will end once 70 percent of those 16 and older are fully vaccinated, whether or not there are new cases. Andrews said the state might reach that vaccination threshold around Oct. 26. About 43 percent of Victorians have been fully vaccinated, 46 percent nationwide. “We will do so cautiously, but make no mistake, we are opening this place
