Since touchdown on Mars one yr in the past, NASA’s Perseverance rover has travelled greater than 3 kilometres throughout the underside of Jezero Crater, recorded the primary helicopter flight on one other planet and picked up six valuable rock samples that — if all goes properly — will in the future be returned to Earth. Jezero provided a shock: its ground is fabricated from igneous rocks, which shaped as molten rock cooled and solidified billions of years in the past. Samples ought to enable researchers thus far rocks from particular locations on the floor of Mars for the primary time. The rover will quickly head to its final vacation spot, an historical river delta, the place it would search for indicators of previous life.

The China Nationwide Area Administration has launched an outline of its plans for the subsequent 5 years, which embody launching a robotic craft to an asteroid, constructing an area telescope to rival the Hubble and laying the foundations for a space-based gravitational-wave detector. The plans proceed the nation’s development in emphasizing missions with science at their coronary heart, somewhat than expertise improvement and purposes, says astronomer Shuang-Nan Zhang. “This can be a excellent signal,” he says. “It’s a steady improve in funding in exploration of the Universe.”

The extraordinary energy of the eruption that devastated Tonga on 15 January, captured by a spread of refined Earth-observing satellites, is difficult concepts concerning the physics of eruptions. Researchers are discovering it onerous to clarify why the volcano despatched an ash plume into the higher ambiance, but emitted much less ash than anticipated for an eruption of such magnitude. And the shock waves that rippled by way of the ambiance and oceans are not like something seen within the fashionable scientific period.
