Hello and welcome to the Intelligence from the Economist. I'm your host, Jason Palmer.

Every weekday we provide a fresh perspective on the events shaping your world.

Satellites don't typically have to move around much once they reach orbit, but some demonstrations

straight out of sci-fi show that space is becoming a battleground. To be able to make

evasive maneuvers, satellites need more power, nuclear power.

And every generation or so, a genuinely new medium emerges and artists find in it a new

place to inhabit. We visit an exhibition by a one-time street artist who's now globally

famous. You can see every single inch of it, too, in the game Fortnite.

And first, Germany's Chancellor Olaf Schultz sat down last night with his Polish counterpart

Andre Duda and flying in at the last was France's president Emmanuel Macron. Mr. Macron

had just come from Moscow, where he claimed to have secured a pledge from Russian president

Vladimir Putin not to escalate tensions on Ukraine's border.

We have, as I said, very precisely yesterday, changed with the president, little Ilma,

saying he would not be the origin of the escalation.

But the Kremlin quickly denied that a deal had been struck, so the parade of international

diplomacy continues. In last night's crisis meeting, Mr. Schultz spoke up, adding to calls

for de-escalation.

But in his tenure so far as Germany's leader, Mr. Schultz hasn't been doing much speaking

up. His critics, on the other hand, have started to say plenty. It's a tense time to say

the least for Germans and for the international community to learn what kind of leader he's

going to be.
