A Nasa pretende um homem e a primeira mulher à superfície lunar. Embora ainda não tenham sido nomeados, um deles também deverá ser a primeira pessoa de cor a pousar na Lua.
Nasa’s Moon programme has been hit by delays, while China aims to land by 2030.
Nasa’s decision to prioritise the safety of the astronauts, and to work with another commercial partner in finding a solution, is a triumph of wisdom and caution.

Nothing is harder to find than you might think.
Si la Terre s’arrêtait de tourner, les conséquences seraient très nombreuses.

Humans might one day be able to live somewhere else in the Universe.
Bumi dapat berhenti berputar jika ia ditabrak planet lain. Jika bumi tidak berotasi, satu hari akan berlangsung setengah tahun lamanya.
Only a planet crashing into it might stop the Earth’s spin.
We have to look back to the Big Bang to find out.
Alien mungkin saja ingin menghubungi kita untuk alasan yang sama dengan kita mencari mereka.
Aliens might want to contact us for the same reasons we are looking for them.
Bumi berputar pada porosnya setiap hari, tetapi gravitasi membuat kita tetap diam di tempat kita berada.
The Earth spins around its axis every day – but gravity keeps us firmly in place.
Not all planets orbit stars. Rogues float through the galaxy in darkness and are almost impossible to see.
If gravity was half as strong, you could jump much higher.
We haven’t heard anything from alien civilisations, but perhaps they’ve heard us.
You could jump much higher on the moon than you can on Earth – but you’d be in no danger of shooting off into space.
Meteorites might look like boring bits of rock – but each one has a fascinating story.
‘Ridge A’ sits at the peak of the Antarctic ice sheet and has exceptionally cold, dry, thin and dark skies.
