Starship Reaches Orbit on Its 14th Try

SpaceX's giant Starship rocket circled Earth for the first time, surviving an engine failure to hit a milestone that changes what space travel might look like.

At 7:48 on a Tuesday morning in South Texas, the ground shook. Starship — the tallest, heaviest rocket ever assembled — lifted off from SpaceX's Starbase facility and punched through the sky. It was the 14th test flight. But this time, something genuinely new was about to happen.

It almost did not. One engine failed during the climb, and for a tense stretch mission controllers debated whether to abort. They decided to continue. The orbit-insertion burn fired as planned, and engineer Daniel Hewitt, narrating the live stream, said the words that made the control room erupt: "Starship is in orbit.

" The rocket had reached an altitude of roughly 275 kilometres — about the height at which the International Space Station circles the planet. Previous Starship flights had only ever traced suborbital arcs, the kind where a malfunction sends debris into the Indian Ocean well away from populated coastlines. Orbital flight is a different category of risk entirely, which is exactly why it had been avoided until now. Martin Barstow, a professor of astrophysics and space science at the University of Leicester, called the achievement "the beginning of the transition from the testing and development phase to becoming a working vehicle.

" That vehicle, he suggested, would one day deliver the heavy payloads needed to send humans back to the moon — and eventually toward Mars. NASA has already selected Starship as the lander for its Artemis programme, meaning this flight matters far beyond one company's ambitions.

SpaceX Cuts Spacewalk Short by Hours

Ten hours. That was the plan. Instead, SpaceX called its astronauts back inside after just 90 minutes — a fraction of what engineers had promised. The mission, which was being watched closely around the world, ended abruptly without a full explanation given to the public. Something had clearly gone wrong, though officials were careful not to say exactly what.…

Having this large launch capability will also be transformational for the whole space industry.

Words That Burned the Amazon

In 2019, a single tweet could apparently kill a tree. Researchers at the University of Bonn tracked 38 posts by Jair Bolsonaro and his ministers that signalled weaker enforcement of environmental law — and then watched what happened next. Deforestation accelerated. The team estimates that those messages contributed to the destruction of up to 1,700 square kilometres of Amazon rainforest — nearly twice the area of Berlin. The effect was strongest in municipalities where Twitter was already busy, suggesting that political signals travel far beyond the screen.…

2GRAMMAR FOCUS
Wish and if only — expressing regret
Use 'wish' or 'if only' + past perfect (had + past participle) to express regret about past events, or + past simple/would to express regret about present situations.
had aborted · had lasted · knew · had not signalled · could explain · had reached · hadn't been cut
  1. Mission controllers almost aborted the flight — if only they the decision sooner, they might have avoided that tense stretch of uncertainty.
  2. The spacewalk was supposed to last ten hours; the astronauts wish it longer than 90 minutes.
  3. The public was given no clear explanation for the early return, and many observers wish SpaceX exactly what went wrong.
  4. The Starship mission short after three hours, and engineers wish the full six loops of Earth had been completed.
  5. If only Bolsonaro's ministers weaker enforcement of environmental law, up to 1,700 square kilometres of Amazon might have been saved.
  6. Scientists studying deforestation wish the world how dramatically a single social media post can influence illegal logging.
3PHRASAL VERBS
Match the phrasal verb to its definition. All six appear in today's articles.
  1. lift off
  2. punch through
  3. cut short
  4. call back
  5. travel beyond
4CRITICAL THINKING
The Amazon deforestation study suggests that political speech can function almost like a direct instruction to clear land. If this is true, should governments be held legally accountable for environmental destruction caused not by their policies but by their rhetoric — and how would you even begin to prove that link in a court of law?

6WRITING
The SpaceX spacewalk was cut short with no full explanation given to the public. Write a short statement, as if you were the SpaceX communications director, that is honest about the incident without revealing sensitive technical details — then reflect briefly on whether such a statement is even possible.
