Coverage for @earthskyscience #spacex#falconheavy#nasa#launch
The theater of operations for #Flight52 of #Ingenuity : up over Mount Julian and down into Fall River Pass.
The animation shows a map with some plausible paths for #Perseverance (green dashed lines), line-of-sight between the rover and the landed heli (red), visibility from the estimated landing location, ground profile, my old landing prediction (green), and the new estimate (yellow). The line-of-sight is obstructed by Mount Julian by 6-7m
Voyager 2: Reservestrom angezapft, Mission um Jahre verlängert
Als die Voyager-Sonden vor 45 Jahren gestartet wurden, sollten sie vier Jahre funktionieren. Ein Kniff soll das Missionsende nun noch einmal weiter aufschieben.
Power to the Voyager spacecraft!
Over the 45.6 years since launch, Voyager instruments have gradually been shut off as power from the RTG has reduced.
It is almost time for Voyager 2 to shut off another instrument, but #NASA engineers have found a way to keep it going for another 2-3 years. A voltage regulator circuit, that keeps the voltage within limits, will be shut off instead.
See graphic below for Voyager power levels and instrument status. https://www.jpl.nasa.gov/news/nasas-voyager-will-do-more-science-with-new-power-strategy #Voyager#Space

This was my thought too after watching closeup slowmo video today:
“The destruction of the launch pad could potentially have contributed to a further issue with the launch: bw 5 & 8 of the 33 Raptor engines appeared not to be firing at various points during the rocket’s ascent. It’s not currently known what caused these engines to fail, but 1 possibility is that material from the destruction of the launch pad, called ejecta, could have damaged them.”
STS-93, 1999 (a Shuttle flight we almost lost on ascent):
“By about T-3 seconds, all engines were up and operating at 100% of rated power level. Exactly when it happened is not clear, but on the right engine, the gold plated pin from LOX post 32 in row 13 came shooting out. Just like a bullet it went through the narrow part of the converging nozzle and flew out into the nozzle extension.”
Not quite the same, but yeah. That kinda debris can do a lot of damage. #NASA
Here is the Mission Control ascent audio of that flight, with diagrams showing who is speaking (and some launch footage alongside it to get an idea what was going on there).
There is a LOT going on and it’s confusing, but give it a go (I’ll watch again too). This is how our flight controller ascent certification sims used to be - but this time it was real! #NASA
Great memory @PaulHammond51 !
Then maybe, "the first time Phobos is viewed in broad daylight from a rover on Mars"? 😀 A few minutes before it took that image it had captured the sun:
My work day today: here are 100 new acronyms that, even after almost 20 years here, you still have not managed to ever see before and we’re not going to define them for you in the document you’re reading.
And we’re not including them in the Center Acronym Finder. Enjoy!
But I did learn that we have an Extended Ocean Vector Winds Mission in my futile search, so there’s that 😁 #NASA and #NOAA!
Great news for anyone working with the Perseverance raw images!
A longstanding issue was recently fixed that applied a linear stretch to the public raw images.
This made it nearly impossible to work with the tiled Navcam images.
Comparison between Sol 501 and 770.
Sharing some of my favorite #Hubble images from the #NASA archives to commemorate the space telescope’s 33rd anniversary. We should take a moment to appreciate the beauty and wonder of the universe.
Information about the images + Hubble facts, a thread: 1/x
Bit of a long shot, but could my good mastodon follower folk give me some boosts?
I'm starting work on a documentary podcast series about the future of space; renewable/sustainable technologies, commercialism in the sector and the public's perception of it all.
I'm hoping to connect with people who know space to complement my client's contacts, so any signal boosting would be appreciated!
