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

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.

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.

I know this may seem for the gaming thread, and I very rarely post on here. But... as I'm sure most will know, Surviving Mars is out and whilst I have never really been one for astrology, meteorology, cosmology... I don't know. I grew up watching and playing the usual stuff that most fans of space exploration do.

But I can't believe how way behind time I am with space exploration. I saw that Elon Must documentary recently and it is probably the most inspiring documentaries I've seen in years. Obviously, I moved onto the game, and have played most space sims (if not all), and watched most space/science films docs.

I had no real idea how much movement there was and in a strange kind of way, both together (the doc and the games), you can see how private enterprise is forming and I have kicked myself for not following the Elon Musk story sooner. Having not read this thread, he is an inspiring bloke, but him along with Richard Branson, could potentially see the first landings  (of some sort) on Mars in our lifetime.

It's blue sky thinking of course, but the whole enterprise perfectly represents the capitalist model/ideology (as well as many others), but it got me thinking about the vertical take-off, landing thing (I don't know the correct term). But those two I mentioned seem to be going about it in different ways and whilst tourism and exploration is the obvious end goal, (as well as... many others), surely the future is some kind of synthesis of Elon Musk's SpaceX engine, and Richard Branson's VSS would eventually be a way of mitigating huma risk, whilst able to somehow eventually merge to the soundtrack of Interstellar.

I'm far from knowledgeable on the subject, but know enough that the joint-effort may go against that ideology and potentially harbour genuine competition. However, when you think of the two techs, the two ideologies, it is surely a perfect match is it not?

I get my science from Hollywood, and I'm one of those "if you can visualise it, you can do it" people who think with their skin. But it is all terribly exciting, and again, we get most of our taste of space via film and TV. So it is very inspiring to see someone literally just burning money away to fulfil that ambition of man.

Yet when you cross the experience of film and TV with a game like Surviving Mars, it is actually very interesting how thinking as to how capitalism and industry may in fact be the overiding formula to a future societal structure. That's all obvious to many on here I'd suspect, but I've never really thought of it in the way Surviving Mars proposes.

I imagine a lot of SM, is of course, guesswork and theoretical physics at its finest and most digestible... But at this moment in time, I think most of us if we had the cash, would like to just fuck the world off and go and explore. A-to-B, mass and propulsion.... etc... being the obvious problem of... and scientific words that I can't be arsed to google.

It's weird how the tech and subject crosses over into many other interests, but stops short of your thoughts because you'd think the media would be ALL over it. I know SpaceX has received coverage, and SpaceX do a good job on their media output (as well as having to keep a lot secret). Yet, I imagine that most of the media coverage is stateside, as well, the ESA looks years behind, but I always got the impression they were years behind, and had other agendas to follow (i.e communication and network).

The network EM is proposing with satellites was interesting, and I found it particularly interesting how they explained how the satellites could look like lights or planets in the night sky... but then fell short of saying they could look like UFO's or other phenomena.

Looked back over a few pages, but I am hoping to binge on some documentaries and read-up as I have a cough and plan to vegetate over the weekend.

Space X launched Falcon heavy for STP-2 mission this morning. Their 1st night launch. This is another Satellite deployment run for the company. But as a side mission, they are also taking up the cremated remains of 100 people including Apollo 11 astronaut Bill Pogue.

The side boosters made yet another perfect landing (watching those land in sync never gets old)

Unfortunately the centre booster missed the landing barge. Though it should be noted that this landing was over 700 miles away from launch so this was considered very difficult

But both the side and centre boosters had already been used on previous missions for Space X so when talking about the sustainability and cost savings it's a huge leap forward. The cost savings up to $100 million just reusing those boosters from the previous mission. If the side boosters can be used again then thats a further saving.

Very significant news today. Kept popping on my news feed. Especially the 120m pounds. Thats cheaper than Phil Coutinho.

Chandrayaan-2: India launches second Moon mission

https://www.bbc.com/news/world-asia-india-49032603

India has successfully launched its second lunar mission a week after it halted the scheduled blast-off due to a technical snag.

Chandrayaan-2 was launched at 14:43 local time (09:13 GMT) on Monday from the Sriharikota space station.

India's space chief said his agency had "bounced back with flying colours" after the aborted first attempt.

India hopes the $150m (£120m) mission will be the first to land on the Moon's south pole.

The spacecraft has entered the Earth's orbit, where it will stay for 23 days before it begins a series of manoeuvres that will take it into lunar orbit.

The lift-off was broadcast live on TV and the space agency's official social media accounts.

There was applause in the Indian Space Research Organisation (Isro) control room minutes after the launch, as the rocket took off towards the outer atmosphere.

It is the most complex mission ever attempted by the agency.

"It is the beginning of a historical journey of India towards the moon," said Isro chief K Sivan in a speech after the launch.

He thanked and congratulated all those who had worked on the mission: "It is my duty to salute all the people who have done the work."

Prime Minister Narendra Modi praised the mission for being "fully indigenous".

The countdown on 15 July was stopped 56 minutes before launch after a "technical snag was observed in [the] launch vehicle system", according to Isro. Indian media have reported that a leak from a helium gas bottle in the cryogenic engine of the rocket was to blame.

The fuel from the rocket was drained and the scientists resolved the glitch.

"It was a simple to fix [but it was] a serious problem that could have resulted in total failure," said a source at Isro.

What is this mission all about?

India's first lunar mission in 2008 - Chandrayaan-1 - did not land on the lunar surface, but it carried out the first and most detailed search for water on the Moon using radars.

Chandrayaan-2 (Moon vehicle 2) will try to land near the little-explored south pole of the Moon.

The mission will focus on the lunar surface, searching for water and minerals and measuring moonquakes, among other things.

India is using its most powerful rocket, the Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk-III), in this mission. It weighs 640 tonnes (almost 1.5 times the weight of a fully-loaded 747 jumbo jet) and at 44 metres (144ft) is as high as a 14-storey building.

The spacecraft weighs 2.379kg (5.244lb) and has three distinct parts: an orbiter, a lander and a rover.

The orbiter, which has a mission life of a year, will take images of the lunar surface.

The lander (named Vikram, after the founder of Isro) weighs about half as much, and carries within its belly a 27kg Moon rover with instruments to analyse the lunar soil. In its 14-day life, the rover (called Pragyan - wisdom in Sanskrit) can travel up to a half a kilometre from the lander and will send data and images back to Earth for analysis.

How long is the journey to the Moon?

The launch is only the beginning of a 384,000km (239,000-mile) journey - Isro is still hoping the lander will touch down on the Moon on 6 or 7 September as planned, despite the week-long delay of the launch.

The journey of more than six weeks is a lot longer than the four days the Apollo 11 mission 50 years ago took to reach the Moon- and land humans on the lunar surface for the first time.

In order to save fuel, India's space agency has chosen a circuitous route to take advantage of the Earth's gravity, which will help slingshot the satellite towards the Moon. India does not have a rocket powerful enough to hurl Chandrayaan-2 on a direct path. In comparison, the Saturn V rocket used by the Apollo programme remains the largest and most powerful rocket ever built.

"There will be 15 terrifying minutes for scientists once the lander is released and is hurled towards the south pole of the Moon," Dr Sivan said prior to the first launch attempt.

He explained that those who had been controlling the spacecraft until then would have no role to play in those crucial moments. The actual landing, he added, would be an autonomous operation dependent on all systems performing as they should. Otherwise, the lander could crash into the lunar surface.

Earlier this year, Israel's first Moon mission crash-landed while attempting to touch down.

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.

If one bothered to read non-western news sources it would have been obvious.

The three space powers of USA, China and Russia were meeting to agree on laws related to the weaponization of space, the Russians and Chinese were pushing for complete non-weaponization which most countries were behind but the Americans kept blocking it. India demonstrated it's anti-satellite tech in order to force it's way into the discussions which is what happened. Geopolitics 101.

Funny NASA condemned it but were nowhere to be seen when USA was bombing satellites and kicking of the militarization of space. Hypocrites!
