From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Keen stargazers may have noticed that the Red Planet has been appearing brighter in the sky since 18 May.
The shape of Earth and Mars's orbits is elliptical rather than circular, and tilted in relation to one another, which means the distance between them can vary a great deal.
Every 26 months, the two planets will ‘approach’ one another, as they line up with each other on their individual ellipses. This is called a ‘Mars Close Approach’ or ‘inferior conjunction’.
However, because the ellipses are tilted, the distance between the two planets as they approach one another will still vary.
The closest the two planets have ever been is 54.6 million kilometres apart, and this is an extremely rare occurrence.
In 2003, Mars was less than 56 million kilometres away – the closest it has been for 60,000 years. NASA predicts that this will reoccur in 2287.
Tonight, Mars will be 75.3 million kilometres away from the Earth, the closest it has been for 11 years.
This is close enough that the planet should be visible to the naked eye, appearing brighter and larger than usual.
Mars will reach its closest – and therefore most visible - point on Monday, and should be visible in the sky for most of the night, reaching its highest point at around midnight about 35 degrees above the southern horizon.
After this, it will begin to fade again and until its next approach in 2018, when Mars will be just 57 million kilometres away.
