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 33.5 metre (110 foot) Terran 1 rocket, built by California-based startup Relativity Space, uses 3D printed engines and a 3D printed structure to lift up to 1,250 kilograms into low-Earth orbit.
The test flight aims to lift off at 1pm local time (6pm GMT), making it “the largest 3D-printed object to attempt orbital flight”.
Terran 1, nicknamed GLHF (Good Luck, Have Fun), will not carry a commercial payload for the first launch attempt, though Relativity Space has already signed deals to deliver satellites into orbit.
In 2022, the company made a multi-launch agreement worth $1.2 billion with UK-based satellite firm OneWeb. The deal will see Relativity Space use its 3D-printed rockets to launch OneWeb’s low Earth orbit (LEO) satellites to boost capacity for its space internet constellation.
Relativity Space claims its novel approach of 3D printing components will significantly reduce the costs of launching rockets, charging roughly $12 million for each flight.
By comparison, SpaceX’s Falcon 9 rocket costs an estimated $67 million per launch, though it is able to carry a much larger payload of more than 22,000kg.
For its first ever test launch of the Terran 1, Relativity Space decided to skip the final static fire test, which is usually a crucial stage of pre-flight testing.
“By not completing static fire, we accept the increased likelihood of an abort on our first launch attempt,” a representative of Relativity Space said.
“But if all systems are performing nominally, we would rather release and launch during our next operation than continue to wear the vehicle through additional testing on the ground.”
If successful, it will also be the first ever privately-funded rocket to reach orbit on the first attempt.
Wednesday’s launch attempt will be live streamed on Relativity Space’s YouTube channel.
“This launch won’t singularly define our long-term success,” said Relativity Space CEO Tim Ellis.
“This launch will, however, provide us with useful data and insights that will make us better prepared for our next at-bat, and is a fantastic learning platform for developing technologies directly applicable to Terran R, giving us a lot of confidence we are ahead in the race to become the next great launch company.”
