ISS toilet fails to suck

Cross-legged astronauts request spares


The Russian ASU (Ассенизационно-Санитарная Установка, or "Waste Management System") aboard the ISS has pretty well clapped out following the failure on 21 May of the unit's air/water separator heralded by a "loud noise", according to NASA.

The agency explained last week: "The crew then replaced the separator with a spare unit but reported afterwards that the ASU lacked suction. The crew next replaced the F-V filter insert, which provided good suction for a while but again exhibited weak suction. TsUP/Moscow instructed the crew to deactivate the ASU and use the toilet facility in the Soyuz spacecraft."

The ASU is a pretty belt-and-braces affair, sucking in a urine/air mix through a funnel, separating the air for recycling into the ISS's atmosphere via a deodorising filter while storing the waste liquid in a tank. Solid waste is likewise sucked into the system via a nozzle for bagging and later disposal.

Women astronauts wishing to take a leak are not, of course, suitably equipped to avail themselves of the funnel, and are provided with sanitary-napkin-type pads.

Despite the ISS crew's best attempts to fix the cantankerous bog, it was still on the blink yesterday, as NASA admitted: "Troubleshooting continues on the Russian ASU toilet facility. Almost all system components have been changed out at this time, including the separator with no improvement in function. Specialists feel the problem is with the separator pump, though they have never before seen this failure signature."

Spare parts are, mercifully, being "last-minute manifested" for Space Shuttle Discovery's jaunt to the ISS due to blast off on Saturday, with NASA hopefully finding space aboard for "a new ASU separator pump".

Discovery's main task on the 14-day STS-124 mission is to deliver the second consignment of the Japan Aerospace Exploration Agency's Kibo laboratory, constisting of the large Japanese Pressurized Module and robotic arm system.

The spacecraft will also drop off new ISS crew member Greg Chamitoff and bring back Flight Engineer Garrett Reisman at the end of a three-month stint aboard the outpost. NASA has a mission summary here (pdf). ®

  • How ICE became a $2.8b domestic surveillance agency
    Your US tax dollars at work

    The US Immigration and Customs Enforcement (ICE) agency has spent about $2.8 billion over the past 14 years on a massive surveillance "dragnet" that uses big data and facial-recognition technology to secretly spy on most Americans, according to a report from Georgetown Law's Center on Privacy and Technology.

    The research took two years and included "hundreds" of Freedom of Information Act requests, along with reviews of ICE's contracting and procurement records. It details how ICE surveillance spending jumped from about $71 million annually in 2008 to about $388 million per year as of 2021. The network it has purchased with this $2.8 billion means that "ICE now operates as a domestic surveillance agency" and its methods cross "legal and ethical lines," the report concludes.

    ICE did not respond to The Register's request for comment.

  • Fully automated AI networks less than 5 years away, reckons Juniper CEO
    You robot kids, get off my LAN

    AI will completely automate the network within five years, Juniper CEO Rami Rahim boasted during the company’s Global Summit this week.

    “I truly believe that just as there is this need today for a self-driving automobile, the future is around a self-driving network where humans literally have to do nothing,” he said. “It's probably weird for people to hear the CEO of a networking company say that… but that's exactly what we should be wishing for.”

    Rahim believes AI-driven automation is the latest phase in computer networking’s evolution, which began with the rise of TCP/IP and the internet, was accelerated by faster and more efficient silicon, and then made manageable by advances in software.

  • Pictured: Sagittarius A*, the supermassive black hole at the center of the Milky Way
    We speak to scientists involved in historic first snap – and no, this isn't the M87*

    Astronomers have captured a clear image of the gigantic supermassive black hole at the center of our galaxy for the first time.

    Sagittarius A*, or Sgr A* for short, is 27,000 light-years from Earth. Scientists knew for a while there was a mysterious object in the constellation of Sagittarius emitting strong radio waves, though it wasn't really discovered until the 1970s. Although astronomers managed to characterize some of the object's properties, experts weren't quite sure what exactly they were looking at.

    Years later, in 2020, the Nobel Prize in physics was awarded to a pair of scientists, who mathematically proved the object must be a supermassive black hole. Now, their work has been experimentally verified in the form of the first-ever snap of Sgr A*, captured by more than 300 researchers working across 80 institutions in the Event Horizon Telescope Collaboration.

    We take a look at low, low subscription prices – not that we want to give anyone any ideas

    A Tor-hidden website dubbed the Eternity Project is offering a toolkit of malware, including ransomware, worms, and – coming soon – distributed denial-of-service programs, at low prices.

    According to researchers at cyber-intelligence outfit Cyble, the Eternity site's operators also have a channel on Telegram, where they provide videos detailing features and functions of the Windows malware. Once bought, it's up to the buyer how victims' computers are infected; we'll leave that to your imagination.

    The Telegram channel has about 500 subscribers, Team Cyble documented this week. Once someone decides to purchase of one or more of Eternity's malware components, they have the option to customize the final binary executable for whatever crimes they want to commit.

  • Ukrainian crook jailed in US for selling thousands of stolen login credentials
    Touting info on 6,700 compromised systems will get you four years behind bars

    A Ukrainian man has been sentenced to four years in a US federal prison for selling on a dark-web marketplace stolen login credentials for more than 6,700 compromised servers.

    Glib Oleksandr Ivanov-Tolpintsev, 28, was arrested by Polish authorities in Korczowa, Poland, on October 3, 2020, and extradited to America. He pleaded guilty on February 22, and was sentenced on Thursday in a Florida federal district court. The court also ordered Ivanov-Tolpintsev, of Chernivtsi, Ukraine, to forfeit his ill-gotten gains of $82,648 from the credential theft scheme.

    The prosecution's documents [PDF] detail an unnamed, dark-web marketplace on which usernames and passwords along with personal data, including more than 330,000 dates of birth and social security numbers belonging to US residents, were bought and sold illegally.
