@eevblog lesson number one

Name the new EEVblog host.

Yes. Yes, I'm absolutely going to use these in video thumbnails from now on.

@DJSnM What about going not out, but in? Kind of Solar probe but smaller? or a mission to Mercury without all the swing-by's?

And while you could possibly send a spacecraft to the outer solar system, it would need a RTG to do anything which isn’t an option.

The plan for Artemis III is a LEO mission to test HLS hardware. That means the ICPS upper stage has almost no work to do, it’ll reach orbit with almost full fuel. After separation it has enough dV to send its cubesats almost anywhere, even interstellar space. Where should it go?

@amsatdl Is Wolfgang qrv?

But there is Ham Radio and the geostationary QO-100 satellite transponder 📡〰️🛰 #hamradio #qo100 #amsat

JY effort The aim of this adventure is driven by the words of HM Hussein. JY1 (SK) but in the heart of many.

@PdxAdvPhoto @MattKik @ExploreSpaceKSC Every time this curtain raises somebody is cutting onions.. been there multiple times and it still gets me.

@MattKik @ExploreSpaceKSC Yeah that was superb stuff by them. I have video of that but I’ve never posted it because I want people to have that wow factor when it’s revealed.

Space Shuttle Atlantis on display with the cargo bay open as if it was in space. I have also included a photo of the heat shield tiles in great detail. This is a such a fascinating and amazing attraction to visit. There is so much more in this building.

@torybruno @jimlux @sleep_deprivado ... and I just learned a minute ago, that there is a volume unit called 'ton'. As if imperial vs metric wasn't enough.

@dh2va @jimlux @sleep_deprivado At least 3...

Blue Ring #1 is moving through testing and doing well. Any interest in pictures?

@jimlux @torybruno @sleep_deprivado I assume this is metric ton. Strange for me to discover there is more than one unit of ton 😳

@torybruno @sleep_deprivado mT= milliTonne? Isn't that just 1 kg? :)

@DutchSpace All the best!

NASA confirms Artemis II WDR-2 is now this Thursday the 19th, T0 at 20:30 EST, (01:30 UTC on Friday) My little app has been updated x37b.nl/artemis/ Source: nasa.gov/blogs/missions… #ArtemisII

Arguments don't sound so unreasonable to me.

@thejackbeyer No air tag left in it by chance?

Los Angeles: please be on the lookout for a shitty rusted blue 2002 Land Rover Discovery 2 w/texas plates. That’s right, my beloved Disco Stu was stolen last night! It has over 300k miles on it and I am cracking up at the idea of the thief dealing with all its quirks.

@blueorigin @grok what is the antenna diameter, what frequency will be used and how much rf power?

Blue Origin's Mars Telecommunication Orbiter (MTO) will accelerate exploration at Mars by ensuring continuity of communications capabilities, supporting tomorrow's science missions, and beginning the enduring infrastructure that will enable future human exploration. MTO offers an integrated solution combining our New Glenn launch vehicle and the Blue Ring Mars capable spacecraft platform. Both have flight-proven heritage. New Glenn is operational, the Blue Ring Pathfinder mission has flown, and multiple units are in production. The scalable open architecture is designed to grow with Mars exploration needs and offers flexible payload capacity for additional science instruments. Learn more at blueorigin.com/mars.

@DJSnM The not so solid booster 😁

Great tracking shot from Max showing a not so great solid booster from Northrop Grumman. (Originally developed by Hercules) ULA fished boosters out of the ocean to help fix this issue, but still we see almost the same nozzle burn through and separation.

@johnkrausphotos @SciGuySpace @NASAAdmin Feels like 7deg ... presumably F, so -13degC. Ouch! Thanks Snap!

@SciGuySpace @NASAAdmin 🥶

@DutchSpace Great, thanks! Will you continue this throughout the mission?

If you want to following along with the Artemis II WDR, i've created this little tool that displays the timeline & live-streams, try it out here x37b.nl/artemis/ Note: it is crappy code, things may break and I might update it "live" so you have been warned :) #ArtemisII

@ibelings @ElectronicsLcsc Which board is this.. 40 USD?

I originally decided to use Enclustra modules for an SDR and homebrew radar, but they are expensive and have too much stuff I don't need. The Artix-7 100T is around $40 at @ElectronicsLcsc

@jdoepker79 @CSI_Starbase Then insulation is probably not optimal. I hope you can stay warm in this current weather.

Oh boy. I have a feeling we will be hearing of people with $1,000-$2000 energy bills in the coming weeks. That storm is no joke both in present and long term effects.

@Marco_Langbroek @DJSnM @planet4589 ssd.jpl.nasa.gov/horizons/news.…

@DJSnM @planet4589 I saw a message somewhere that HORIZONS will have trajectory data about 20h before launch

Does anyone have numerical trajectory data for Artemis II that they are willing to point me to? It's getting close to launch and I don't have anything quantitative on orbital parameters for the various mission phases.

two more days for us to prepare

@planet4589 If we volunteers shall track Artemis II, it is just fair to let us know where to point our antennas to 😉

@dh2va OK that's great news, thanks

The list of participants contains a lot of good friends. This is going to be fun!

Proud to contribute to this study on behalf of the Physics Department of the University of Zurich! Looking forward to contribute together with young scientists!
