Other Workshops: Mission to Jupiter's Icy Moons: The Making of JUICE: The Full Movie


I really like this film.  The enthusiasm of the people involved comes through very clearly.  They love this project.  At the end, you can see a person from the ESA team crying with emotion when they received word that telemetry had been picked up from JUICE -- it had survived the launch. 

Imagine the difficulties involved in doing this across many countries and many languages, in the midst of the COVID pandemic.   Three cheers for all those who made this happen. 

I put this in the "Other Workshops" category.  At some points the workshop seems to be all of Europe.  At other times (like when they move JUICE to the test facility) it seems like one specific place. 

I wonder how the procedures we see in this film compare to the famed spacecraft-building procedures of the Jet Propulsion Laboratory in California.  But just remember:  When it came time to launch the Webb Space Telescope, NASA opted to launch from the ESA facility in French Guiana.  Their Ariane rocket apparently had a better success rate than ours.  But it did seem to me that they did discover problems with some of the instruments in the thermal phase of the "shake and bake" but then corrected them without re-running the thermal tests.  Was that a violation of test principles? 

Watching this movie makes me really want to take out my small telescope and aim it at Jupiter (which is now high in our evening sky). 

We see a lot of "soul" built into this new machine:  the inclusion in the spacecraft of a copy of pages from Galileo's Starry Messenger and the names of those involved in the project, and the selection of the faring logo from a children's contest,  for example.  Yaryna, the young Ukrainian artist who drew the logo at age 8, even mentions "soul" in her remarks.  

Godspeed, JUICE!

Jam on Radar Antenna of Jupiter-bound Spacecraft FIXED! Antenna deployed!

Great news. This stuck antenna was getting me down.  Three cheers for the ESA folks who fixed it from afar.

Here is how they did it:

The RIME antenna looks a bit like one of my dipoles! But it can look 9 km into the ice. 

And what a great name:  Jupiter Icy Moon Explorer.  Juice. 

Godspeed JUICE!

Europa -- "Attempt No Landing There."


As we get ready to send two probes to the Galilean moons of Jupiter, this sci fi movie made its way into my feed.   It is pretty good, and the ending will appeal to all true radio amateurs.

Ganymede and Jupiter as seen by Juno


But remember the warning:

"All these worlds are yours, except Europa.  Attempt no landing there."

Daytime Occultation of Venus TODAY! LUNCHTIME (on East Coast)



Thanks to my Michael EI0CL for alerting us to this.  It will happen today, very conveniently at lunchtime on the East Coast of North America.  I may have to bring my Soviet binoculars to work.

Details here:  http://spaceweather.com/

It has already been a nice day for astronomy here in the wilds of Northern Virgina.  National Public Radio on Sunday alerted me to the fact that Mars is high in the pre-dawn sky.  Our friend Armand e-mailed alerting me to possible clear skies this morning.  The leaves are down and no longer obstructing my view of the Southern sky.  With my six inch telescope I got a very nice view of Jupiter and the four Galilean moons.  We are pretty far away from Mars at this point, so I could see no surface feaures, but it is always nice to see that distinctively red disk. And Venus is poised to disappear behind the moon.  

Good luck with Venus and the Moon.  Please send in reports. 

And speaking of occultations, check this one out (thanks to Farhan for the alert):


The moon passed between Nasa's Deep Space Climate Observatory and the Earth, allowing the satellite to capture this rare image of the moon's far side in full sunlight. We normally don't see this side of the moon. As the moon is tidally locked to the earth and doesn't rotate, we only ever see the one face from the earth. Awesome shot!

NASA needs Ham Help! Say HI to Juno (on its way to Jupiter) on 10 meter CW!


This is really interesting:

Jupiter In the Morning

Jupiter is high in the early morning sky now, and the weather is starting to cool off a bit here. Here is the configuration of the Galilean moons that I saw on September 11. This is from the Sky&Telescope on-line Jovian moon display.

I've even been able to do some "sidewalk astronomy" in the style of guru John Dobson: I have the telescope set up on my driveway, and I offer the pre-dawn dog walkers a look at Jupiter and Galileo's moons. They are always very pleased. It is a nice way to start the day!
