Among Orbán's many corrosive effects in Hungary, he politically strangled universities and research funding. His defeat offers the possibility of a better, more open future for Hungarian science.

SR-1 will use bits of the "power and propulsion element" designed for the canceled Lunar Gateway. Primary development will be done in-house.
Now let's get NASA's budget restored so it can carry out other great missions, including exploration of Venus & seeking habitable worlds.

We have more details about NASA's planned Space Reactor-1, which will test nuclear-electric propulsion technology to travel to Mars.
It will carry three Mars helicopters that will land via a novel "skyfall" technique. Science instruments on SR-1 are planned but TBD.

Viktor Orbán has conceded in a speech to supporters, telling them: "The result of the election is clear and painful."

What could we be getting wrong?
Maybe we live in an atypical corner of the cosmos, giving us a misleading view.
Maybe we're missing something fundamental about the early evolution of the universe.
Either answer has huge implications.

A new study confirms the "Hubble tension": measurements of the local expansion of the universe do not line up with measurements of how the universe was expanding after the Big Bang.
It's no simple experimental error. 11 different techniques agree.

Did you recognize our Moon? It's one of the new photos from Artemis II.

One is Pluto's moon Charon.
One is Earth's moon, the Moon (aka Luna)
A little shift in perspective, and even the most familiar objects in space look surprising and new.
It is astonishing that humans are able to do these things. This is what happens when we act collectively to solve extremely difficult technical problems. (It works with many other kinds of problems, too, by the way.)
You can follow Artemis II's encounter with the Moon starting at 1pm EDT.
Beautiful shot & beautiful metaphor. The "Man in the Moon" drifting off at right. The lunar farside coming into view at left. (Processing: Damian Peach)
From the evolution of the eye, ~500 million years ago, until October 7, 1959, no creature on Earth had ever seen the far side of the Moon. #space #science #artemis #technology
