Launch vehicle

ESA has asked Russia to contribute a Proton rocket for ESA’s planned Juice mission to the Jupiter region in 2022. This would become a joint ESA-Roscosmos mission. (31 May, 2012). Source: [1]

Sadly the SpaceNews URL doesn't work now. Did Roscosmos respond ? - Rod57 (talk) 11:59, 21 October 2022 (UTC)[reply]
Seems Ariane 5 was chosen as launch vehicle by Dec 2011, see p5 of JUICE yellow book - Rod57 (talk) 11:44, 21 October 2022 (UTC)[reply]

Targeted moons

The moon Io is listed as one of the target moons, however, the mission's home page does not mention any science to be performed on Io. Cheers, BatteryIncluded (talk) 17:18, 11 January 2013 (UTC)[reply]

The mission science documents state that JUICE could conduct small-scale remote observations of Io for specific objectives like plume evolution, but then it will study similar targets of opportunity throughout the mission. I think that's why someone put it there. However I'd say this isn't significant enough to be considered amongst the primary targets which are clearly the icy moons and are the only ones JUICE will perform flybys around.

JUICE (JUpiter ICy moons Explorer)

The name used by ESA is JUICE (JUpiter ICy moons Explorer), with plural "moons". Would someone like to correct the article title? Dondervogel 2 (talk) 15:44, 3 October 2016 (UTC)[reply]

 Done. - BatteryIncluded (talk) 21:20, 3 October 2016 (UTC)[reply]

Sonic the Hedgehog as mascot for the RPWI instrument and its missions?

In October 2019, I heard one of my video game characters was chosen as the mascot for Japan's Radio & Plasma Wave Investigation, with permission of Sega and a special logo to go with the equipment. This is the primary source cited for this announcement, such as this Kotaku article; it does look verifiable as part of the Tohoku University (a prestigious one) website. Is this worth mentioning or 'nay? ❤︎PrincessPandaWiki (talk | contribs) 22:48, 6 June 2020 (UTC)[reply]

Quick edit: The article linked in the heading does mention this, so it's likely worth mentioning. I dunno where to put it in the article, though. ❤︎PrincessPandaWiki (talk | contribs) 22:50, 6 June 2020 (UTC)[reply]

All the dates in the article are wrong. Launch is planned for 2022 not 2023

From a source linked to in this very article: "The mission will be launched from Kourou with an Ariane 5. The baseline launch window is between 26 August – 15 September 2022, with a backup launch slot in August 2023"

I've seen other sources with a June launch date in 2022 as well. Not sure which is correct.

Now the article (and NASA & ESA websites) says April 2023. For years (2011...2015-2017-2020?) it was due to launch in 2022. Would be nice if article could say when and why it was delayed until 2023 (Covid-19 ??). - Rod57 (talk) 18:27, 12 April 2022 (UTC)[reply]

What delta-V from the 4 gravity assists

Could we say : What delta-V will it gain from each of the 4 gravity assists ? Would other launchers have been able to reduce the number of GA's and travel time ? - Rod57 (talk) 11:06, 21 October 2022 (UTC)[reply]

JUICE yellow book Dec 2011 says
"Launch is foreseen on an Ariane 5 ECA with direct escape with an Earth-Venus-Earth-Earth gravity assist sequence. With the baseline launch date in June 2022 (backup in August 2023), a JOI, preceded by a Ganymede gravity assist manoeuvre, would be performed in January 2030, after 7.6 years (for the backup launch in August 2031 after 8 years). The mass injected into the Earth escape trajectory would be 4800 kg (without launch adapter), with a hyperbolic escape velocity of 3.15 km/s, which increases to 9.5 km/s after the last Earth swing-by."
Is that a 6.35 km/s delta-V ? Interesting that now it is due to launch in April 2023, possibly with different planetary flyby sequence ? - Rod57 (talk) 11:51, 21 October 2022 (UTC)[reply]

What does the JUICE spacecraft and launch cost

Article should answer : What does the JUICE spacecraft and launch cost ? Initial budget ? Final cost ? - Rod57 (talk) 20:26, 8 April 2023 (UTC)[reply]

NASA budget (for instruments?) $114 M [2]
ESA, In 2012 BBC [3] say "The mission will cost Esa on the order of 830m euros (£695m; $1.1bn) over its entire life cycle. This includes the cost of manufacturing the spacecraft bus, or chassis, launching the satellite and operating it until 2033." - Rod57 (talk) 20:32, 8 April 2023 (UTC)[reply]
mmm.. the double, 1600 millions of euro[4] [5]. Kirk39 (talk) 14:09, 12 April 2023 (UTC)[reply]

Why Io?

Is there a reason why this odd phrase is being kept in the article? [6]

"The mission is not focused on the volcanically active Io, a non-icy moon."

Why the investigator and funding agency?

I feel like the fields that attribute each instrument to one or more investigators and to the corresponding funding agency come out directly from the PR kit. Can we remove it? Resincognita (talk) 22:23, 15 April 2023 (UTC)[reply]

It really does feel like the list is a bit too comprehensive for an encyclopedia; I would think that a short compiled summary on the nature of the instruments (ie. what kind of instruments does JUICE have? what do they do?) written in prose, as opposed to a list, would be more appropriate.
