The first vertical takeoff and landing test (VTVL) for the Zhuque-3 reusable methane-powered carrier rocket was successfully conducted in the Gobi Desert in northwestern China on Friday afternoon, according to its developer LandSpace, a Chinese commercial aerospace company.

The company said that the test flight lasted for about 60 seconds, with the trial rocket reaching a height of approximately 350 meters above the ground. The rocket landed 100 meters away from the liftoff point with a precision of about 2.4 meters.

The company said that the full-sized trial rocket prototype verified the key technologies for the first stage of Zhuque-3, which is set to be launched in 2025. These technologies include variable-thrust technology with a wide range and landing guidance and control.

The expansion of the universe at some stage of evolution is well described by the Friedmann model. It was derived from general relativity a hundred years ago, but it is still considered one of the most important and relevant cosmological models.

RUDN University astrophysicists have now proven the theoretical possibility of the existence of traversable wormholes in the Friedmann universe. The research is published in the journal Universe.

“A wormhole is a type of highly curved geometry. It resembles a tunnel either between distant regions of the same universe or between different universes. Such structures were first discussed in the framework of solutions to the gravitational field equations a hundred years ago. But the wormholes considered then turned out to be non-traversable even for photons—they could not move from one ‘end of the tunnel’ to the other, not to mention going back,” said Kirill Bronnikov, doctor of physical and mathematical sciences, professor of RUDN University.

Walmart-backed EV startup Canoo has announced that deliveries of its all-electric commercial van have officially begun – and the first production Canoo LDV 130 vans are already hard at work.

The first batch of Canoo’s electric vans are reportedly in service now at Kingbee, a national work-ready van rental provider. The company says the delivery of vans to Kingbee is consistent with its previously announced “phased ramp-up manufacturing approach,” and asserts that additional customer deliveries will continue throughout 2024.

Canoo had previously delivered vehicles to NASA, the US military, and the State of Oklahoma (its home state) for testing. The vans delivered to Kingbee, however, seem to be the first that will be accessible to “the public.”
