Physicist Dr Paul Coxon has helpfully condensed the decade-long mission into a single tweet. 

It's been retweeted the European Space Agency account, too.

Ben Bagshawe was evacuated from his home on Fontmell Close on the night of 1 October last year. along with his heavily pregnant wife Gemma. Their baby boy was born a week later.

At the time they told the BBC they left their house clutching her notes and a bag that was packed in readiness for a trip to hospital.

"We were asleep when we were awoken by this awful rumbling sound like an earthquake," Gemma Bagshawe said.

"Ben jumped out of bed and got to the window, then I heard him say 'the road has gone'."

We recently caught up with them and found they have been renting a flat for the past year, with the cost covered by insurance.

"It's been frustrating but not the end of the world," Ben Bagshawe said.

"It's annoying having a kid and not being able to be in your home... but hopefully we'll be back by Christmas."

They can't drive directly down their road, having instead to negotiate a temporary road built across a nearby heath. They look out of their house onto what looks like a building site and, in a situation which normally provokes complete horror on social media forums, they can't park their car right outside their house...

But Rosemary and Derek Broom, who have used their neighbour's drive since a hole opened up outside their house in Fontmell Close, St Albans, on 1 October last year, have always said "we can't complain".  

While four households have been unable to return home, the Brooms are the closest residents to the hole who have been able to remain in their house for the past year (pictured). 

Mrs Broom said: "We have no reason to complain and everyone has really pulled together.

"The council has sent emails and put letters through the door to keep us informed, we've never complained about anybody, we can't fault anybody, they've been brilliant.

"People ask us why we're so upbeat, but we say we look at it positively, we're alright, we've been helped, everyone's rallied round and no-one's been hurt."

A couple who live next to the site in Fontmell Close, St Albans, where a large hole opened up a year ago, say their road is now "the safest place to live in the country", because so many investigations have been carried out on the ground beneath.

Rosemary and Derek Broom are the closest residents to the hole who have been able to remain in their home, and have remained positive throughout.

A full microgravity survey and exploratory drilling established the hole was caused by historic mine workings. A subsequent ground subsidence investigation report found the past mining operations were "effectively contained" within the footprint of the collapse and no evidence "indicated further significant mined voids".

Mrs Broom said: "The roads, the fields, the children's play area, everything has been so well surveyed we don't feel at all worried."

Mr Broom added: "We heard one of the test bores was 150ft deep and if you've gone down that far and found nothing, you're OK."

Work is continuing at the site of the St Albans sinkhole in Fontmell Close, to restore utilities to the houses surrounding the hole and open the road again.

Hertfordshire County Council said Thames Water had already rebuilt its sewers and Affinity Water completed mains pipe repairs this week.

The site has now been handed over to the National Grid, which will re-establish the gas supply and UK Power Networks is due to take over on Monday for two weeks to restore electricity.

BT and Virgin will then take two weeks to lay phone and cable television connections.

Once all this work is complete, the council can reinstate the roadway and pavements.  

County councillor Terry Douris said he had been "impressed by the considerable cooperation amongst all of the utility companies" and the authority "appreciates the patience of the residents" while it tries to remedy the situation.

One year on from the appearance of a large hole in a St Albans cul-de-sac, Hertfordshire County Council says it is working to re-open the road before Christmas.

The 33ft (10m) deep hole appeared in Fontmell Close, a former clay pit site, on 1 October last year.  

Four families who had to move out of their homes are still waiting to return, as investigations into the cause of the collapse meant utilities have not yet been restored, and the road has not re-opened.

Hertfordshire County Council hopes all the work will be completed by Christmas.

Councillor Terry Douris said: "It was essential we established the cause of the collapse before we started repairs.

"This has been an extremely stressful time for the residents and it would be wonderful if they can be safely back in their homes for Christmas.

"If all goes to plan, we will do everything we can to have the road re-opened by then, and we hope householders and their insurers can reach agreements to allow them to return home."

"It's been a fantastic achievement for Hertfordshire engineering."

Those are the words of Andy Jones, who was in charge of building the Rosetta spacecraft at Airbus Defence and Space in Stevenage about 12 years ago. 

Speaking to BBC Three Counties, he said today's deliberate crash will be a "sad" day for him, but it's been "fantastic" as the craft had "done its job". 

He's got mixed feelings about today as he "spent five or six years" of his life building it. 

The European Space Agency says operations are going as planned.

The Rosetta spacecraft, which was built in Stevenage and involved scientists from the Open University in Milton Keynes, will be deliberately crashed into the comet it's been tracking this morning.

It will mark the end of the mission which started in 2004 at Airbus Defence and Space in Hertfordshire.

Rosetta's mission was to explore the origins of the solar system by studying Comet 67P, which took ten years to reach. A small lander, Philae, was sent down to the surface.

Later today Rosetta will follow with a 19km descent, crashing on the surface at roughly walking pace at about 12:20.

The decision was taken because the comet is now heading so far from the Sun that soon its solar panels will not be able to generate enough power to keep it functioning.

You can follow its progress via a special BBC live feed, and we'll bring you the major updates throughout the day.

I'm in Stoney Grove in Chesham, where yesterday the body of a woman was discovered at a house in the road.

I've spoken to one eyewitness who told me there was "lots of police activity going on" all day and another, who had lived in the road for 15 years, told me this was "a very quiet road" usually and he was "astonished".    

Thames Valley Police said a 41-year-old man from Chesham is in custody and officers have called it an "isolated incident".
