What can satellites reveal about climate tipping points?

The effects of our warming climate are seen across a multitude of measures, usually as incremental changes: more frequent extreme weather, heatwaves, droughts and wildfires. The cumulative impact of these changes, however, can cause fundamental parts of the Earth system to change more quickly and drastically. These ‘tipping points’ are thresholds where a tiny change pushes the system into an entirely new state.
This week, at ESA’s Living Planet Symposium, scientists came together to discuss the latest research evidence for climate tipping points and identify the opportunities and challenges of using remote sensing data to understand them.

Boeing Starliner completes key test mission to ISS, with some hiccups
Wednesday, 25 May 2022 23:01 Write a comment
Boeing's Starliner capsule returned to Earth Wednesday in the final step of a key uncrewed test flight to prove itself worthy of providing rides for NASA astronauts to the International Space Station.
The spaceship landed in a puff of sand at 4:49 pm local time (2249 GMT) in the New Mexico desert, wrapping up a six-day mission crucial to restoring Boeing's reputation after past failures. Starliner concludes OFT-2 test flight with landing in New Mexico

Spacesuits are leaking water and NASA is holding off any spacewalks until they can solve the problem
Wednesday, 25 May 2022 13:31 Write a comment
NASA's spacesuits are getting old. The extra-vehicular mobility units—EMUs for short—were designed and built for spacewalks outside NASA's space shuttles, which flew for the last time in 2011. Nowadays, the EMUs are an integral part of maintaining and upgrading the International Space Station (ISS) exterior, providing the crew with the ability to live and work in the vacuum of space for extended periods of time (spacewalks regularly last from 6 to 8 hours). However, at the end of the most recent spacewalk on March 23, NASA astronaut Kayla Barron discovered water in the helmet of German astronaut Matthias Maurer while she helped him remove the suit.
Historic Greenland ice sheet rainfall unravelled

For the first time ever recorded, in the late summer of 2021, rain fell on the high central region of the Greenland ice sheet. This extraordinary event was followed by the surface snow and ice melting rapidly. Researchers now understand exactly what went on in those fateful summer days and what we can learn from it.

Boeing's Starliner capsule is readying to return to Earth on Wednesday in the final step of a key test flight to prove itself worthy of providing rides for NASA astronauts to the International Space Station.
The spaceship is scheduled to autonomously undock at 2:36 pm Eastern Time (1836 GMT) and touch down in New Mexico just over four hours later, at 2249 GMT, wrapping up a six-day mission c InSight's Final Selfie

NASA's InSight Mars lander took this final selfie on April 24, 2022, the 1,211th Martian day, or sol, of the mission. The lander is covered with far more dust than it was in its first selfie, taken in December 2018, not long after landing - or in its second selfie, composed of images taken in March and April 2019.
The arm needs to move several times in order to capture a full selfie. Becau NASA-supported solar sail could take science to new heights
