It’s a bird. It’s a plane. No,it’s a 60-foot mirror designed to reflect sunlight back to Earth after dark.
The US government has given a start-up the green light to build a 142kg satellite that will be launched about 650km above our heads.
Eärendil-1,about the size of a fridge,will then unfurl a thin square mirror that reflects the sun’s rays to illuminate a three-mile-wide stretch of Earth.
Looking up,you would see a dot about as bright as the full moon,according to maker Reflect Orbital’s website.
The Federal Communications Commission (FCC),which regulates tech,approved a license for a ‘single demonstration satellite’ on Thursday.
Reflect Orbital wants to send its first space mirror up this year,with the aim of launching 50,000 satellites by 2035.

Doing so would light up the night sky for several hours by 36,000 lux,the unit of measurement for light – an amount comparable to daylight.
But the constellation of mirrors would illuminate the world below by 100 lux all the time,about as bright as the inside of a lift or corridor.
The idea behind the ‘solar reflector’ is that it could make ‘clean energy available on demand’ via the company’s app or website.
‘Turn it off instantly when you’re done,’ the website says,listing example uses such as lighting up an emergency scene,construction site,or farm.
All of this will come at a price – and a hefty one at that. Reflect Orbital would charge about $5,000 an hour for the light of one mirror if a customer signed up for a year-long contract.
The company’s co-founder,Ben Nowack,said in March that shining one-time events or emergencies would be more costly.
