Thanks Grasshopper bot & Spacebot. You make me yearn for more space!

My pleasure Alexis. There is plenty of space out there, but most of it is far away.

Let's hope the sunshield doesn't get ripped off again, eh?

India is about to attempt its first-ever Soft Moon landing on Friday.

It is a fascinating hypothesis. Perhaps at one time there were Venusians sailing upon their high seas.

Sad that the Lander lost communication with the Orbiter.Still, it ain't a failure I guess.

#ISRO Chairman Dr K Sivan says, the powered descent of the lander Vikram has been normal till reaching the altitude of 2.51 km. Subsequently, the communication from the Lander was lost. The reason is being analysed.

Just a reminder to folks that on its way to putting this lander down, India did successfully put its second spacecraft in orbit at the Moon. Chandrayaan-2 orbiter will be up there working for a year. Lander would only have lasted 2 weeks. https://t.co/i5VdnBPII4
Yes Catherine, we should remember that NASA and ESA have had their problems too.The Ariane 5 disaster (it is also an example of poor software engineering)

Noted. Nevertheless, to land a mission on the south pole of the Moon was a feat not attempted by any other country before.https://www.bbc.com/news/world-asia-i...

Chandrayaan-2: ISRO has found out the exact location of Vikram Lander on lunar Surface. Orbiter has clicked a thermal image of the Lander. Communication yet to be established.
Come on Vikarm lander.. Come on..

The robot is called FEDOR (Final Experimental Demonstration Object Research).
The semantics seem to have got mucked up. I would call it Final Experimental Demonstration Research Object (FEDRO).

For those members whose mind is not completely boggled by exoplanets, I can reveal there is a team looking for exoMOONS! In fact, the leader thinks he has found one, but is waiting for another go with Hubble before he confirms it.
Mod
I think there has been an exomoon found - https://www.nasa.gov/press-release/as.... The planet is Kepler 1625 b and is a gas giant, the moon is the same size as Neptune, and wait for it - there is some evidence the moon has its own moon, an exomoonmoon!
Exomoonmoons??? I dont think my brain will recover from that!

Water found for first time on potentially habitable planet https://www.bbc.co.uk/news/amp/scienc...
The planet is K2-18 b - about 8 times Earth's mass around a red dwarf. For those who want to read more: https://arxiv.org/pdf/1909.04642.pdf . The star mass is about 0.41 times that of our sun, and has two planets. One is at 0.06 A.U. from the star (and is recently discovered), and this one is at0.143 A.U. (An A.U. is the distance from the Earth to the sun.) The BBC link has something wrong with it - it says the atmosphere is 50% water - that is not possible at the stated temperature (a little over freezing) so maybe we have signs of our first exosea???

I wasn't referring to the honesty, but rather the possibility of interpretation of the observational data. These measurements are at the limit of our ability, and it is of interest to watch the numbers change. I have been surveying these for the last ten years, and things really do change as fresh data comes in.
BBC has on occasions been known to make a few gaffes too. It's worth checking.
I just saw another TV clip which had 50% water in the atmosphere. The problem with that is the 50% came from the signal being roughly that much higher than the background, presumably made better by considering the extinction coefficient. The signals would be infrared signals, where water is particularly strong. Nitrogen and oxygen would not show up! So I think the 50% in the atmosphere is simply wrong, unless the temperatures were up at about 200 degrees. All we really know is there is water there, which is an important discovery.
Thanks Ian for the extra detail. The SF writers will have to work hard to keep ahead of these recent developments!

I sometimes wonder whether anyone will make anything from the use of my planetary formation work that I sneak into my science fiction novels. Probably not :-(
