Apparently NASA have abandoned attempts to contact Opportunity. I am very sad at this news.  :'(

Sadly, all good things must come to an end. But that bugger has been 15 years in service! The best mission we have built since I joined 17 years ago. Curiosity or Mars 2020 will never compare to that, both will be short-lived compared to Spirit and Opportunity. True, new instruments will yield better science data, but IMHO, corners have been cut to meet the schedule and the capabilities of those instruments have been compromised. They will still meet their respective science goals, which are usually set low, but we could have gotten so much better data if all went well. Maybe delaying a mission by two years is not such a bad trade-off...

Maybe it's the five pints, but I'm rather emotional.  It's like losing Patrick Moore all over again!

Opportunity has to be in the top five robotic space probes - unlike Voyager or even Cassini, it spoiled us rotten; really giving us a long lived, sol-to-sol experience of another world, and going banzai into one crater after another.  It became part of the furniture and will be sorely missed.

As Scott Manley said, of Opportunity's last message:

"My batteries are dying... and it's getting dark."

Heartbreaking!!

Ah yeah, but you're talking about a robotic rover that was meant to last 90 days but instead went on for 15 years - not sure your quote is all that accurate. ;) ;D

Nothing interesting from NASA, but there are a few interesting missions launches to look to:
2019 February 19 - Beresheet - Launch of Israeli lunar lander
2019 NET March 25 - Chandrayaan 2 - Launch of ISRO (India) lunar orbiter, lander, and rover
2019 September - OSIRIS-Rex - Sample collection from asteroid Bennu
2019 Late - Chang'e 5 - Launch of Chinese lunar sample return mission

The InSight instrument deployment phase was successfully completed two days ago. All instruments are in great shape! The hammer will soon be released and the seismometer will get a taste of real data.

I see there's a bit of a hoohaa about that Indian anti-satellite test the other day.

The debris is quite possibly extending up into the ISS orbit.

I'm not sure quite why they (India) thought it necessary other than the usual regional dick swinging and the upcoming elections.

Anyone else watch the BBC4 Doc about the Black Hole photo last night at 9pm.  Absolutely brilliant it was.

The first privately funded mission to the Moon will attempt to land on the lunar surface today.

The Israeli spacecraft - called Beresheet - will try for a soft touch down, before taking pictures and conducting experiments.

Until now, only government space agencies from the former Soviet Union, the US and China have achieved this.

The mission has cost about $100m, paving the way for future low-cost lunar exploration.

It’s a great achievement being the first private enterprise to the moon, but is it achieving much scientifically? I ask that genuinely as bbc article doesn’t provide all that much.

Damn... But that should not be a discouragement, most learning comes from failures.

It is incredible how we take successful landings for granted, even though history suggests low success rates. And landing from orbit is far easier that straight ballistic entry, descent and landing (EDL). The Viking landing on Mars was from orbit, everything else afterwards - EDL. And we still need to wear brown pants when it happens...

There's a brilliant BBC4 documentary on this they've followed the whole process and is narrated by Peter Capaldi.

You have 29days to watch it on iPlayer

How to See a Black Hole: The Universe's Greatest Mystery


Quote
For two years BBC cameras have followed, Dr Sheperd Doeleman of the Smithsonian Astrophysical Observatory and the work of the Event Horizon Telescope project team, a collective of the top scientific minds from around the world. The project combines radio observatories and telescope facilities from around the world to make up a virtual telescope with a diameter spanning the entire planet. This mega-telescope’s ultimate mission is to capture the first image ever of a black hole. Although the concept of black holes has been long assumed to be fact, the Event Horizon Telescope’s success would definitively prove the existence of this scientific phenomena for the first time – and provide clear visual evidence.

The programme brings viewers into the laboratories, behind the computer screens and beside the telescopes of what may prove to be one of the great astrophysical achievements in human history.

I love the fact the code was written in Python using numpy, matplotlib, etc, and it’s on github for anyone to review https://github.com/achael/eht-imaging

The fact the reconstructed image (not picture or photo as some papers have called it) resembles the simulations is great.
