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.

Two veteran cosmonauts sailed through a six-hour spacewalk outside the International Space Station yesterday to prepare the orbital outpost for a new module and better shield its living quarters against small meteorite and debris impacts, officials said.

Station commander Gennady Padalka and flight engineer Yuri Malenchenko opened the hatch on the station's airlock at 11:37 am EDT (1537 GMT) to begin a spacewalk to relocate a construction crane, install debris shields and release a small satellite into orbit.

Their departure was delayed about an hour while engineers assessed a leak between the Pirs docking module and Russian segments of the station, a $100 billion laboratory for microgravity experiments and technology testing that flies about 250 miles (400 km) above Earth.

But the issue was resolved and the experienced spacewalkers more than made up the lost time.

Padalka, who was making his ninth spacewalk, and Malenchenko, on his fifth, moved a hand-operated, 46-foot (14-meter) crane, called Strela-2, from the outside of Pirs to Zarya, the cornerstone of the station. Pirs is due to be detached from the station next year to make room for a new Russian laboratory and docking module.

The United States completed construction of its part of the outpost last year and retired its three space shuttles. Europe, Japan and Canada also are partners on the project.

With the crane in place, the spacewalkers then used a hand tool to launch a 20-pound (nine-kg) spherical satellite on a path behind the space station.

"Nice throw," a flight director in the Russian mission control center outside Moscow said through a translator monitoring radio communications with the cosmonauts.

The satellite, which is expected to remain in orbit for about three months, is intended to serve as a target for Russian engineers working on computer models that evaluate orbital tracking.

The spacewalkers' last major task was to install five debris shields to the outside of the Zvezda module, the crew's primary living quarters. They also retrieved a briefcase-sized experiment that has been exposing various materials to the harsh environment of space and installed two support struts on a ladder.

Padalka and Malenchenko returned through an airlock and shut the hatch at 5:28 p.m. EDT (2128 GMT), completing the 163rd spacewalk for station assembly and maintenance.

On Aug. 30, NASA astronaut Sunita Williams and Japanese astronaut Akihiko Hoshide, both station flight engineers, are scheduled to make another spacewalk to replace a power relay unit on the station's truss, set up power cables for the Russian laboratory module scheduled to launch next year and install a thermal cover on a docking port.
