To guard against cyberattacks in space, researchers ask “what if?” | Ars Technica
Because space is so remote and hard to access, if someone wanted to attack a space system, they would likely need to do it through a cyberattack. Space systems are particularly attractive targets because their hardware cannot be easily upgraded once launched, and this insecurity worsens over time. As complex systems, they can have long supply chains, and more links in the chain increase the chance of vulnerabilities. Major space projects are also challenged to keep up with best practices over the decade or more needed to build them.
Voyager 1 Is Back! NASA Spacecraft Safely Resumes All Science Observations | Scientific American
After more than six months of long-distance troubleshooting—Voyager 1 is more than 15 billion miles from Earth, and any signal takes more than 22.5 hours to travel from our planet to the spacecraft—mission personnel have finally coaxed Voyager 1 to gather and send home data with all its remaining science instruments, according to a NASA statement.
