Just because the US government is shut down, it doesn't mean your voice is. Contact your representatives and tell them what NASA science means to you. Your voice will help to inspire the generations that come after us. Learn more here: www.planetary.org/save-nasa-sc... @planetarysociety.bsky.social

NEW: It was a delight to contribute to @quantamagazine.bsky.social's stunning new series on climate science! Naturally, my story tended apocalyptic: will Earth ever become a climate hellhole like Venus, the most extreme world in the solar system?
www.quantamagazine.org/why-is-venus...
Venus is a Solar System enigma.
Although Venus is similar in size and distance from the Sun to Earth, it has evolved very differently from our planet.
Our #Envision mission will aim to solve some of the puzzle by thoroughly studying our closest neighbour.

(4/4)๐ฐ๏ธ Diverse tectonic #activity is revealed at 52 Venus coronae based on topography and gravity; the VERITAS mission may uncover hundreds more:

(3/4) ๐ Our new Venus coronae #database, open to all, includes 740 structures โ the most ever catalogued โ and identifies several morphological subsets:

(2/4) ๐ The #first 3D geodynamic models of Venus rift tectonics reveal 5 modes of rifting. Venus' rifts may be active and shaped by evolving or laterally variable lithospheric and crustal properties:

We are pleased to invite you to the Online School โIntroduction to Geodynamic Modellingโ. The event is organized by the COST Action EUROBIG and hosted by the Institute of Geological Sciences, Polish Academy of Sciences.
Registration is open until 15 July 2025:

If you are interested in supporting NASA science and exploration, and saving it from capricious budget cuts, here's one thing you can do: sign this petition being sent to Senate and House members of their respective appropriations committees. Two days left to sign!

We're going to learn some tough stuff today about the White House's proposed budget for fiscal year 2026โincluding what they have in mind for NASA.
I'll share what I hear, but remember:
CONGRESS decides how much money NASA gets, not the White House.
So whatever happens today, the fight continues.
NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.
How bad will it be? Catastrophic.
Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.
But, this is the WH's *proposed* budget.
Speak up now before it is too late.
(inflation adjusted $-s below)
Write and urge your Senators to co-sign Mark Kelly's letter supporting NASA science: planet.ly/senateletter
Deadline is FRIDAY.
The study was posted today in Science Advances and was co-led by @unibe.ch researcher @planetaryanna.bsky.social and University of Maryland Baltimore County + NASA Goddard researcher Gael Cascioli.

Previously published #Venus coronae databases, however, remain inaccessible to the public and/or incomplete -- our new database uses clear ID criteria to define 740 (!!) corona features on Venus, which is much higher than ever reported!
agupubs.onlinelibrary.wiley.com/doi/10.1029/...
"#Coronae" are defined by a (partial) quasi-circular ring of closely spaced concentric fractures. They are hugely abundant on #Venus' surface and considered key for Venus' tectonic and volcanic history โ๏ธ๐

We are rebooting the biannual computational geoscience and geoydnamics meeting - please join this CIG sponsored event in Breckenridge CO this summer - EC support available.
geodynamics.org/events/detai...
:-) :-) :-) 10 fully-funded PhD positions :-) ::-) :-)
Please forward to anyone who might be interested. We offer 10 PhD positions at the interface of geology, ecology and geography. In particular, I would like to promote subproject 6 (see figure).

It was such a pleasure to attend #LPSC25 last week and present my latest #Venus #science work, some originating from my time at NASA Jet Propulsion Laboratory; @caltechseismo.bsky.social. These presented studies will likely soon result in some exciting publications (stay tuned...)!
