Putin Calls Musk a Genius. Why Flatter a Rival?

As Russia races to build its own satellite network, its president praised the man whose switch can dim Ukraine's battlefield.

Here is a strange scene. In Moscow, surrounded by African leaders, Vladimir Putin stops to praise an American billionaire. "Elon Musk is a genius, a true genius," he said, according to the Tass news agency. Why would a wartime president hand out compliments to the owner of his enemy's favourite technology?

Look at the numbers, and the flattery begins to make sense. Putin said Musk has "more than 5,000" satellites in orbit, though the true figure for active SpaceX craft is estimated at about 10,000. Russia's answer, a constellation called Rassvet, is in its "first steps". Outside analysts estimate it has roughly 26 working satellites.

That is not a rivalry. It is a gap the size of a sky. The gap matters because Starlink is no longer only about streaming video. In mid-October, its military version, Starshield, was suddenly restricted one night in Ukraine.

Discuss
  • Why might Putin praise Musk publicly while Russia is fighting a war against a country that depends on Starlink?
  • Putin said Musk has 5,000 satellites, but the real estimate is about 10,000. Why might the figure be understated?
  • Starshield was restricted for about ten days in Ukraine. What does this show about relying on a private company in wartime?

Tiny Crystals Ride Around the Moon

More than 10,000 tiny crystals flew around the Moon in 2022, strapped inside two mannequins. Why? Radiation. Polish physicists in Cracow supplied crystals that record particle tracks, like film, and later glow red under blue light. Early readings suggest lunar-trip radiation differs from low Earth orbit in unexpected ways.…
  • If crystals can map invisible radiation, what else might they reveal about astronaut safety?

Earth's Magma Was Hiding Extra Oxygen

Oxygen makes up more than half the atoms in Earth's silicate interior, yet textbooks said molten rock could hold only a fixed amount, set by its other elements. Wrong, it seems. Using crushing pressures and computer simulations, researchers led by Yanhao Lin and Ho-kwang Mao found that magma can absorb surplus oxygen.…
  • If magma once released stored oxygen, how much credit should volcanoes get for our atmosphere?

2GRAMMAR FOCUS
Third conditional — hypothetical past
Use the third conditional to talk about unreal situations in the past and their imagined results: if + past perfect, would/could/might + have + past participle.
had · hadn't · would · wouldn't · have · been · could
  1. If Musk restricted Starshield that night, Ukrainian drone defences would not have been hampered.
  2. If Russia's Rassvet network had been larger, Putin have needed to praise Musk so warmly.
  3. Zelenskyy might not have announced the restoration of operations if the service been switched back on.
  4. If Musk had not closed the loophole, the Ukrainian military have kept using the civilian service.
  5. Putin have called Musk a genius if Russia had matched SpaceX's satellite numbers.
  6. If the Polish physicists supplied their crystals, the mannequins would have flown around the Moon without radiation detectors.
3PHRASAL VERBS
Match the phrasal verb to its definition. All six appear in today’s articles.
  1. hand out (as in 'hand out compliments')
  2. make sense (as in 'the flattery begins to make sense')
  3. ride around (as in 'crystals ride around the Moon')
  4. make up (as in 'oxygen makes up more than half the atoms')
  5. close down (as in 'he had closed a loophole'; in related usage, to shut something off)
4CRITICAL THINKING
Both the Starlink story and the magma story overturn something people assumed was fixed: that a military's communications belong to the state, and that rock can hold only a set amount of oxygen. Which assumption was more dangerous to hold, and what does each case suggest about how we should treat 'settled' knowledge? Consider who benefits from an assumption staying unquestioned.
