    The three Americans and one Canadian slated to fly on NASA's Artemis II circumlunar mission had a "pinch me" moment Monday when they got their first chance visit the Orion spacecraft that will carry them around the Moon and back to Earth.

    The astronauts had an opportunity to peer through the hatch of the Orion crew capsule for the Artemis II mission, now largely complete and going through some final tests before it is connected to its power and propulsion module at NASA's Kennedy Space Center in Florida.

    "We all said when we walked up to it the first time, that it gave us chills, and it really does," said Christina Koch, a mission specialist on the Artemis II mission. "So it's a new way that I feel bonded with this crew and also with the team."

    About three months have passed since NASA's Orion spacecraft splashed down into the Pacific Ocean after a flight beyond the Moon and back. At the time, the space agency said the Artemis I mission had successfully met its goals and paved the way for humans to follow suit.

    This week, after carefully reviewing data from that Artemis I mission since splashdown, space agency officials reiterated that although there were a few minor issues with the flight, overall it bolstered confidence. As a result NASA's chief of human exploration for deep space, Jim Free, said the agency is targeting "late November" of 2024 for the Artemis II mission.

    During this flight, four astronauts—likely including a Canadian—will spend a little more than a week in deep space. After checking out the performance of Orion in low-Earth orbit, the spacecraft will fly into what is known as a "free return trajectory" around the Moon, which will bring them as close as 7,500 km to the surface of the Moon before swinging back.

      SolarWinds patches vulnerabilities that could allow full system control

    SolarWinds patches vulnerabilities that could allow full system control

    SolarWinds, the previously little-known company whose network-monitoring tool Orion was a primary vector for one of the most serious breaches in US history, has pushed out fixes for three severe vulnerabilities.

    Martin Rakhmanov, a researcher with Trustwave SpiderLabs, said in a blog post on Wednesday that he began analyzing SolarWinds products shortly after FireEye and Microsoft reported that hackers had taken control of SolarWinds’ software development system and used it to distribute backdoored updates to Orion customers . It didn’t take long for him to find three vulnerabilities, two in Orion and a third in a product known as the Serv-U FTP for Windows. There's no evidence any of the vulnerabilities have been exploited in the wild.

    The most serious flaw allows unprivileged users to remotely execute code that takes complete control of the underlying operating system. Tracked as CVE-2021-25274 the vulnerability stems from Orion’s use of the Microsoft Message Queue, a tool that has existed for more than 20 years but is no longer installed by default on Windows machines.
