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.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. 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.

The US space agency used a tool called a Seismic Experiment for Interior Stricture (SEIS) to capture the sounds of vibrations and weather systems on the Red Planet.
The dome-shaped instrument sits on the surface of Mars and uses wind pressure, temperature and magnetic sensors to assist the seismometer in detecting dust storms, meteorite impacts and even marsquakes.
“We’ve been waiting for this moment for a long time,” said Philippe Lognonne, a principal investigator at Nasa.
“It’s been 130 years since the first seismic record on Earth and almost 50 years since a seisometer was placed on the Moon during the Apollo program. What we learn from SEIS will shed light on how Mars formed and evolved.”
The SEIS instrument belongs to Nasa’s InSight robotic lander, which landed on Mars in November 2018.
Many of the sounds picked up by the tool could not be easily explained by Nasa scientists, with the space agency describing these phenomena as “peculiar”.

Nicknamed “dinks and donks”, the sounds may be coming from parts within the seismometer itself, which expands and contracts when it heats up and cools down.
The recordings were made between March and July 2019 but have only just been released to the public through Nasa’s Soundcloud and YouTube channels.
Two recordings from 22 May and 25 July captured marsquakes with registered magnitudes of 3.7 and 3.3.
“It’s been exciting, especially in the beginning, hearing the first vibrations from the lander,” said Constantinos Charalambous, an InSight science team member at Imperial College London.
“You’re imagining what’s really happening on Mars as InSight sits on the open landscape.”
