Window cleaning meets the final frontier as cosmonaut gets the sponge out

NASA shares a photo of a space-based window cleaner.

NASA astronaut Zena Cardman has shared some striking photos showing a Russian cosmonaut during a spacewalk.

One of the images (above) shows Alexey Zubritsky performing what is a mundane task on Earth but something altogether more challenging when you’re orbiting Earth 250 miles up: window cleaning.

“Caught Alexey Zubritsky, on one of his recent spacewalks, through the window of his own sleeping quarters,” Cardman wrote in a post on X. “After installing a semiconductor experiment with Sergey Ryzhikov, Alexey had the task of wiping off the outside of his window.

“I loved the juxtaposition of something so hugely sublime as a spacewalk with something so relatable as cleaning a hazy window that you’ve been looking through for months.”

Cardman described Zubritsky worksite around the window as a “difficult” one, with “not much to hold on to, but Alexey is a natural at spacewalking.”

She added: “Totally surreal to be right there, inches from our friend.”

The photos were taken by Cardman at the end of October but shared only in the last few days due the U.S. government shutdown over the last month, which saw NASA pausing communications across its social media platforms.

The American astronaut arrived at the space station in August and is set to return to Earth in the first half of next year.

During her time aboard the orbital outpost, and up until the shutdown started, Cardman has been sharing various images and videos of her experiences in space.

In August, a few weeks after her arrival, the astronaut posted a video of a SpaceX cargo spacecraft docking with the ISS high above Earth.

Boop! We have a new Dragon at the bow of our @Space_Station. This one is full of cargo instead of friends, but the whole crew is excited for research experiments (and food) on board. @AstroIronMike and @JonnyKimUSA did a great job monitoring the approach from 1km out all the way… pic.twitter.com/D6SbfFZa0J

Cardman also shared a video of a dramatic moonset, which shows our nearest neighbor appearing to become weirdly distorted due to the effects of Earth’s atmosphere.

A moonset viewed from the station occurs when the moon appears to move below the horizon of the Earth. Unlike on Earth’s surface, the ISS orbits the Earth about every 90 minutes, so the moon can seem to set very quickly from an astronaut’s perspective.

NASA is investing $590 million in private contractors to build humanity’s first Moon outpost
NASA is counting on private companies to land its Moon Base dream.

Building a permanent base on the Moon sounds like science fiction, but NASA is making it feel a lot more real. The agency just handed $590 million in contracts to three private companies for four uncrewed lunar lander missions launching in late 2028.

These missions are part of Phase 1 of NASA's broader $30 billion Moon Base program, which needs to deliver landers, rovers, and scientific cargo up there before astronauts eventually move in. These efforts are closely tied NASA's Artemis program, which sent humans on a lunar flyby in April for the first time since the Apollo era.

Getting to Mars may require a pit stop in orbit, and NASA just tested the nozzle to make that happen
A gas pump nozzle for spacecraft sounds simple. It is not, and that's what makes this test worth paying attention to.
Architecture, Building, Factory

Getting a spacecraft to Mars or beyond requires an enormous amount of fuel, most of which has to be hauled from Earth, adding to the overall cost and weight of the spacecraft. NASA has been working on a different approach, one that could be more efficient and effective.

It wants to refuel a spacecraft in orbit before heading out for the mission. What’s even more interesting is that the space agency just finished testing a component that could make that possible: a cryocoupler.

Elon Musk’ Starlink could soon offer mobile services as a US carrier
Showcase of T-Mobile Starlink service on an iPhone.

Elon Musk’s Starlink has already changed how millions of people access the internet, especially in places where traditional broadband struggles to reach. Now, the satellite internet service could be preparing for an even bigger leap — becoming your mobile carrier.

According to a Financial Times report, SpaceX has told investors it’s considering launching a retail Starlink mobile service in the US. Instead of simply partnering with wireless carriers, the company could begin selling mobile plans directly to consumers, putting it in direct competition with Verizon, AT&T, and T-Mobile.
