The daughter of the space scientist behind the Beagle 2 project has said her late father would have been pleased to "defy the critics who wanted to say that Beagle 2 is a failure".
Professor Colin Pillinger's daughter Shusanah said: "He would have loved that this shows Beagle 2 landed on Mars, it got all the way through the entry and descend and the processes. It unravelled some of its solar panels.
"This shows such an immense success and not forgetting all the other things that went on in the background of Beagle 2, all the promotion of science, all of the inspiration to children.
"He would love that this is in the news again. He would love that this could inspire that next generation to do Beagle 3."
Adding that his death last year had been tough for her family, she said: "We are trying to carry on what dad would have wanted. He was someone who wanted science to be communicated to everybody. We want everybody to be aware of Beagle 2, to be inspired by it.
"But there is a tinge of sadness that he can't be here. You can see that in the room where all his colleagues, all the people he worked with, everybody is gutted he cannot be here."
Many people have been taking to Twitter to express their sadness that Professor Colin Pillinger didn't live to see that the Beagle 2 spacecraft did successfully land on Mars after all.
The mission was led by the Professor, and he died assuming that the craft had been destroyed after it went missing in 2003.
However, the UK Space Agency today confirmed that high resolution pictures taken by Nasa's Mars Reconnaissance Orbiter spacecraft showed it actually successfully landed 12 years ago.
Utterly incredible to see that the #Beagle2 has finally been found on Mars. Sad that Prof Colin Pillinger isn't alive to see this.
Amazing news that they've found #Beagle2 intact on Mars! So sad Colin Pillinger isn't here to learn his spacecraft wasn't lost after all.
The Beagle 2 spacecraft did successfully land on Mars, the UK Space Agency has confirmed.
The craft went missing on Christmas Day in 2003, and many scientists assumed that it had been destroyed.
David Parker, the chief executive of the UK Space Agency, announced today that Beagle 2 did land on Mars, but "only partially deployed."
Beagle 2 was built in Stevenage, and the mission was led by Professor Colin Pillinger of the Open University in Milton Keynes.
On the day that the Conservative Party unveiled their election manifesto, Labour has used the east to launch its attack, criticising David Cameron's failure to include the NHS at the top of his election pledges.
Ed Miliband was in Stevenage where he made it clear that the NHS is Labour's priority.
The health care system is likely to be a big election issue after a bleak start to 2015 for our health services...
Addenbrooke's in Cambridge was named as one of the worst performing for A&E waiting times in our region.
Major internal incidents were declared at Addenbrooke's and Peterborough City Hospital, with black and red alerts at others.
The private company running Hinchingbrooke in Huntingdon pulled out of its contract for the NHS Hospital.
Today Ed Miliband said Labour would turn around the fortunes of the NHS with more resources.

Politicians who recommend leaving the European Union risk making the country more vulnerable to terrorism, Ed Miliband has suggested during a Q&A in Stevenage.
The Labour leader, who was in Paris yesterday to show solidarity after the Charlie Hebdo attacks, said cross-border co-operation over security was crucial.
Speaking at an event with voters in Stevenage, Mr Miliband reiterated that he wanted the UK to stay in the EU.
"Think about terrorism and counter-terrorism. We are much better working across borders to do that," he said.
"Think about our economy... I just think we are much, much better working within the EU than not."
Asked afterwards whether Mr Miliband thought the Paris attacks had strengthened the case for staying in the union, a senior Labour source said: "It's certainly his belief that security is one of the issues where working across the EU shows its obvious benefits.
"We all remember from 7/7 that the European arrest warrant (EAW) played a vital role in bringing those suspects back to Britain. The EAW has been a very useful tool in dealing with security issues since it was introduced."
Pressed on whether that meant politicians who wanted Britain to leave the EU were endangering people, the source said: "I wouldn't back away from that interpretation.
"I think security is an important part of what the EU does."
Ed Miliband has been taking part in a Q&A session with an invited audience in Stevenage.
The Labour leader spoke for around 80 minutes this morning, answering questions from the group of pre-selected people at Stevenage Arts and Leisure Centre.
Stevenage is a target seat that Labour wants to win back in the General Election.
Network Rail is facing a multi-million pound fine after overrunning engineering works caused thousands of trains to be cancelled on one of the busiest days of the year.
An investigation has been launched after the "unacceptable problems" which caused King's Cross to close. The East Coast mainline runs from King's Cross, through Stevenage and Peterborough to Scotland.
Network Rail's managing director Robin Gisby apologised for the mayhem saying he was "deeply sorry" for the disruption.
He added: "We've had an army of 11,000 engineers out over Christmas Day and Boxing Day at 2,000 locations nationwide.
"Over 90% have been completed and handed back to-time but I realise this is no consolation for the thousands affected today."
He said Network Rail would pay compensation to train operators, but would not say whether affected customers will be in line for pay-outs.
In July this year the firm was fined a record £53.1 million by the rail regulator for "shortfalls in performance".
The Department for Transport has called today's rail disruption "extremely disappointing" and appeared to point the finger at Network Rail for failing to meet deadlines for engineering works.
A spokesman for the Government department said passengers will be "rightly annoyed" by the delays and cancellations to services including East Coast, First Hull Trains, Grand Central and Great Northern.
"This was essential work but passengers need to be able to plan and rely on Network Rail meeting its deadlines for having the network back in service.
"The department is in contact with Network Rail to understand what went wrong and if lessons can be learned for the future."
Thousands of rail passengers in our region faced disruption after one of the country's busiest train terminals ground to a halt.
East Coast trains which runs from King's Cross through Stevenage and Peterborough to Scotland cancelled dozens trains due to overrunning engineering works.
As King's Cross came to a standstill it led to a quieter scene at Peterborough this morning with a reduced to and from the station. Passengers were advised to delay travelling until Sunday or Monday.
Network Rail has apologised to customers for the delays.
