Russia might send up rescue ship for ISS crew
Russia is examining the flight worthiness of a Soyuz crew capsule docked with the ISS that sprang a leak last week, and might need to send up a rescue vessel for stranded crew, officials said Thursday.
The vehicle, known as MS-22, began spraying its coolant into space on December 14, with dramatic NASA TV images showing white particles resembling snowflakes streaming out of the rear.
In a press briefing organized by the US space agency, Sergei Krikalev, who leads human spaceflight programs at Russia's Roscosmos, told reporters the damage was being assessed.

As NASA's Mars InSight mission comes to an end, JPL engineers say farewell to its twin
Pranay Mishra reached down to the floor of his workplace and scooped a handful of what might be the closest thing on Earth to the feel of Martian soil.
"This is actually unprocessed garnet," he said, sifting the gray granules in his palm. Tiny ruby-colored flecks caught the light. Mixed with diatomaceous earth, a fine powder of algae fossils often used by gardeners, the coarse gray stuff makes a decent substitute for the density and texture of Mars' dirt. The only difference is that on Mars, no one has to clean it up.
"I've torn up three pairs of shoes working in this," the JPL systems engineer said with a laugh. "It follows you home. It's in your car, it's in your house—it's everywhere."
At some point in the next several weeks, a critical amount of actual Mars dust will cover the solar panels of NASA's InSight lander, which has been studying the red planet's crust, mantle, core and seismic activity since 2018. The batteries won't generate enough voltage to keep the spacecraft's instruments online.

Investigation into Soyuz leak continues
As astronauts completed a delayed spacewalk outside the International Space Station, NASA and Roscosmos officials said they are continuing to study whether a Soyuz spacecraft that suffered a coolant leak can safely return its crew home.
Chile's ALMA observatory resumes work after cyberattack
The ALMA telescope in the Chilean Andes has resumed operations nearly two months after shuttering due to a cyberattack, the observatory said Wednesday.
ALMA, the world's most powerful telescope for observing molecular gas and dust, studies the building blocks of stars, planetary systems, galaxies and life itself, according to the European Southern Observatory (ESO), its co-operator.
