Engineers have repaired an issue affecting telemetry data from @NASAVoyager 1 that was identified earlier this year. While the team continues to investigate the root cause, the spacecraft appears healthy and continues to gather and return science data. go.nasa.gov/3R2vfZH
RT @GLOBEatNight: btw 18-27 Aug, measure night sky brightness w @GLOBEatNight from ur computer, tablet, or smartphone 2 raise public awareness abt light pollution. We’ve reached 12k data points. Let’s reach 20k by the end of 2022!

This diagram, from the 'The Voyager Uranus Travel Guide', shows the different trajectories of Voyager 1 and Voyager 2. I love the shell-like graphic. #Voyager45@NASAVoyager
The Voyager Golden Records are endlessly fascinating. In the 90 minutes of music, there is 1.24 seconds of Yolngu music from Milingimbi Island in the Northern Territory of Australia. Who were the Aboriginal musicians who are going to the stars? #Voyager45theconversation.com/beyond-t…
But of course I love Voyager 1 as well - its 45 launch anniversary is on Sept 5 - here @lucidkevinor and I talk about the spacecraft crossing that invisible line between our world and the next theconversation.com/voyager-…#Voyager45
This is my long interview with Voyager 2, through the amazing @pffli who continues to represent the spacecraft on Twitter. I think you'll agree that Voyager 2 has a diffident charm that is utterly beguiling. zoharesque.blogspot.com/2012…#Voyager45
This galaxy is so far away that the expansion of the universe is causing it to recede from us faster than the speed of light. Weirder: it has ALWAYS been receding faster than light. When the photons we are now seeing were first emitted, they were moving directly AWAY from us.
I wrote about the discovery of what could be the most distant galaxy we've ever seen. You're seeing this cosmic tomato as it was just 300 million years after the Big Bang.
Important caveats in here, but also lots of wonder about what comes next: theatlantic.com/science/arch…
RT @NASAWatch: This from @SpaceXStarlink TOS. Yes, people will b arguing abt the Outer Space Treaty but it is interesting 2 see a company thinking ahead 2 providing services 2 people offworld. Or maybe this is a @SpaceX lawyer having a little fun. Or both.
HT @NewsfromScience: A shiny green beetle is eating its way through N American forests, leaving a wake of dead ash trees. A new analysis predicts ash might not recover. ow.ly/Y8hr30rbpyd
I have some of the last living American Ash trees on my property in WV... ;'(
HT @JPMajor who has been posting today on color perception and the photos from spacecraft, and gave a great link to @DDAVISSPACEARTwork on color calibration of planetary imagery, with a great section on Mars: donaldedavis.com/PARTS/MARSC…
This is a view of #Earth from the surface of Mars, captured by NASA's Spirit rover on March 8, 2004 (mission Sol 63).
That's us, that star in the sky. 🌎
Very cool (and scary) video from @AGItweets which shows how crowded low Earth orbit will become over the next 10 years if all proposed #satellites launch. And btw this is in addition to the other 20,000 other #space objects which are already being tracked. Space needs rules!
