Do you know about snapplanet.io? I've been playing around on it at the breakfast table, keeping an eye on the #Greenland#glaciers I have instruments on and it's just struck me again how mindblowing it is that I can download and process on my phone and for FREE a world's worth of high resolution satellite images from #ESA#Sentinel2. The future is amazing.
Here have a free image of Inglefield Bredning in NW Greenland yesterday. #snapplanet
First Metal 3D Printer on Space Station dribbles molten Steel.
The first metal 3D printer aboard the International Space Station successfully dribbled out a molten “S curve” last week, in what the European Space Agency (ESA) is calling a “giant leap forward for in-orbit manufacturing.”
Did you know that it's actually NASA/ESA/CSA James Webb Space Telescope? Even though it is often referred to as "NASA" only.
European Space Agency #ESA has contributed the NIRSpec instrument, half of the MIRI instrument, and the launch (including the payload adapter & launch site services) and has 15 scientists working at the science and operations center. #CSA, the Canadian Space Agency, has contributed the NIRISS instrument.
Tomorrow, 12:00 CEST, #ESA and the @ec_euclid will present 15 papers, including first #astronomy results:
5x #ESAEuclid reference papers about the main mission, the instrumentation, and related cosmological simulations
10x Early Release Observation #science papers, ranging from ... near to far
At the same time ESA will make 5 new ERO images public as well as the underlying science images. This programme was observed before the start of Euclid's main survey.
Expect new images and first science results from #ESAEuclid coming Thursday, 23 May. Five new stunning images, first ten science papers plus five #Euclid reference publications.
There will be broadcast by #ESA as well as press and paper releases by ESA and us. Stay tuned!
What is #ESAEuclid? It's a physics experiment and an #ESA space mission 🛰️ - but foremost it's a project imagined, designed, built, and operated by more than 2000 scientists, engineers, and technicians 👩🔬 👨💻 👩🔧.
We are now starting a series of #blog-posts showcasing a cross-section of the people behind #Euclid
Video of sun’s surface shows solar rain, eruptions and coronal moss
"Scientists say the observations of the sun’s complex surface dynamics could help resolve the question of why the sun’s atmosphere is so much hotter than its surface – a longstanding paradox in solar physics."

These unofficial Mastodon accounts of space agencies are bots that merely share news items the agencies publish elsewhere, yet the accounts have quite a lot of followers:
This is the surface of a comet! Dust is swirling around the surface of Comet 67/P -- captured in 2016 by ESA's Rosetta spacecraft, processing by Jacint Roger Perez.
Still one of the most remarkable scenes in space exploration.
So excited/humbled to have #ESA and my partner institutes in #Oslo this week to discuss #CIMR LEVEL-2 products!
#CIMR is an upcoming #Sentinel satellite that will help us monitor the #Earth and its #Climate in the polar regions.
We are at the start of an exciting 4-year activity, the #L2PAD, to prepare #OpenSource algorithms and products for this satellite. Can't wait to meet the team, it will be the first time I meet some of them in person.

That's exciting! May they be nice to you and offer delicious cookies!
If I may be so bold, I have a few questions wrt satellite use.
Is #Sentinel#CIMR going to be a dedicated satellite or does the device go piggy-back on another?
When new measurement devices are introduced, is it part of the plan to later consolidate satellite use, ie put more and more devices on a single sat where compatible, once the first of their carriers get de-orbited and replaced?
What is the weight & life expectancy of the new CIMR #satellite and what is its decommissioning procedure – burn up or shoot outside Earth's orbit?
You probably guessed it: my questions relate to #sustainability in general, to space debris, and most of all: the impact of burnt-up satellite material on chemistry and climate.
An institution like #ESA can set the tone so rogue, unregulated actors like #Starlink might soon be reigned-in before their bad biz plan lets 27t of satellite material burn up – every single day!
