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.

We're going to learn some tough stuff today about the White House's proposed budget for fiscal year 2026—including 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.

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.
