Smile, a European-Chinese mission, began science operations after its ultraviolet camera caught a daylight aurora over the North Pole. The July frames show the hardware works, and findings on solar particles and Earth's magnetic field still await more data and a recalibrated X-ray imager.

Geoscience Australia's public Sentinel-2 tool maps vegetation moisture at 20-metre resolution about every five days. In the ACT, rated normal risk by the national outlook, it showed a dry south and faster drying than in most recent years.

ESA cleared the joint European-Chinese Smile mission for science on 23 September, after 95 days of commissioning in orbit. Its aurora camera is recording now, while the X-ray imager meant to map the magnetopause waits for stray light to fade in mid-October.

UC San Diego physicists compared eight Planck polarization maps against each other and recovered the same 0.37-degree twist as the standard analysis. The agreement gives cosmologists a second way to ask whether the rotation is in the sky or in the instrument, though the authors stress it does not confirm the twist is real.

ESA's Juice spacecraft needed one small nudge, from six correction slots set aside, to line up a 28 September Earth flyby that added 3.5 km/s. Its operators say the unburned propellant will go to observing Jupiter's icy moons; ESA has not said how much was saved.

NASA's next flagship survey telescope will watch hundreds of millions of stars for one-off gravitational blips. That is how you count Earth-mass planets you will never get to look at a second time.

The creep was about 10 millimetres a month, far too slow to trip any threshold set in advance. Manoochehr Shirzaei's preliminary read is that nobody was screening for the change in its rate.

Webb watched Chariklo, the first small body found to have rings, cross in front of a star in 2022, and the ring opacities it measured do not match the ground-based ones from the previous decade. The paper offers three explanations.

The IMBIE team merged 42 independent satellite surveys from 27 missions to account for 11.3 trillion tonnes of ice lost from Greenland and Antarctica since 1979, and it assigns 84% of that loss to glaciers accelerating into the ocean.

UC San Diego physicists cross-checked eight Planck polarization maps and found their relative calibration matches the standard analysis. The test cancels any rotation all detectors share, so the hinted 0.37-degree twist still needs an absolute angle reference.
