The JUNO probe reaches Jupiter - *www.bbc.com/news/science-environment-36710768
Also, the name Juno is a joke with a 400 year old setup - When Galileo discovered Jupiter had moons each was named for one of Jupiter's mistresses. In an hour the Juno spacecraft, named for his wife, will arrive. A joke scientists have setup over 400 years. : spac

yes, we have been overlooking this important mission to the big jupiter here, even though this mission is a first of its kind.
to start with, whats going to happen, we may check out the juno trailer :

# this spacecraft is first one thats powered by solar panels, on a mission to exo-solar orbits. previous ones were powered by plutonium rod or something, but, scarcity of suitable radioactive stuff & advancement in solar cell technology made this happen.
the 3 tennis court long panels could have produced 14-15 kilowatts of power on earth, powering an entire office/school building (non-ac) or a few residential homes. but the same will make 400-500 watts @ jupiter's orbit, to power its instruments adequately.
# the mission orbit will be an elliptical orbit, designed to get into very close poisonous fields of jupiter for a relatively short period of time (14 hrs i guess), to collect the data, then rush out from the field by firing up the engine to a greater distance, to save itself from the radiation and transmit the data back to earth. it's described here :

nasa youtube channels have already started uploading information, science data and live streams, to keep us fans up to date (i wish isro did share science data and findings like nasa does, but all isro does, is share some pretty pictures and keep the science data mostly private, no matter what they find). we can have an audio visual experience of one of those here :
[YOUTUBE]8CT_txWEo5I[/YOUTUBE]
finally, as juno approaches, more and more pictures start to show up, here the approach video from junocam, over a time span of 48 hrs (fast forwarded ofc) : callisto is the farmost & dimmest, io is the closest fast mover, in between are gaynemede & europa :

i also hope, while moving so fast near jupiter, juno doesn't collide with some weird interplanetary objects.

Path to be taken by Cassini before it will plunge into Saturn.

I didn't know NASA planned to dump it into the planet.

The probe will get destroyed pretty quickly due to all the pressure.
Saturn does not have any hard surface that you can stand on. Its basically a huge mass of gas. It is said that if Saturn were to be placed on a large body of water, it will float, so low is its density.
There might be a solid surface deeper, but there is no evidence so far.

and we are still struggling with a proper GSLV launch. *sigh*
on an other side, furthest star discovery by hubble scope happened after 900 crore years of light travel. thanks to some kind of galactic lens thing.
Hubble images farthest star ever seen
Hubble Uncovers the Farthest Star Ever Seen

Rest assured no other nation in this world made as much space mission progress as India per dollar spent.It will take at least a dozen GSLV failures consecutively to justify the above statement.Space mission & Atomic program are the only two things done by India which are recognized by the world(as real scientific achievements).
Voyager and Hubble are awesome missions no doubt. However, the GSLV did not fail. The satellite failed to achieve the target altitude, the launch vehicle performed flawlessly. In the previous IRNSS launch, the deployment mechanism of the heat shield or nose cone failed. Despite these failures, ISRO rocket launches are the cheapest and most reliable in the world.

^ those may be true, but after 40 years of working in the field, the only reliable launcher is our hand is the 25 yrs old low payload launcher psalv. it has been long, and should have mastered medium payload launching by now and should have started planning for heavy launchers.
sometimes cost effectiveness is not the only measure to success, we need to run against the time too.

^^What you are saying holds true for a rich/developed nation,not India which is neither rich(like China) nor developed(like many EU nations). Nations like USA,Russia,China need to race against time because of their strategic & commercial goals.In India where almost half billion people are not even considered "properly literate"(in India definition of literate incl able to write own name & few other basic things) even a world class PSLV is a real achievement.Btw out of last 40 years only the period from 1995 onwards count as before 1991 economic reforms India was essentially a poor country.

Few days ago, japan landed rovers / landers / hoppers on asteroid ryugu, that can hop, float & move around on the asteroid surface.
