Video: NI couple Lynne and Noel Hanna begin record-breaking Mount Everest quest
Check out our gallery of incredible pictures from their journey so far
It's a challenge like no other as a Northern Ireland couple have embarked on their bid to become the first husband and wife team in the world to climb Mount Everest from both sides.
Lynne (54) and Noel (49) Hanna from Dromara are at the beginning stages of their gruelling 8,700 metre, seven-week ascent of the treacherous north side of the mountain.
The Belfast Telegraph featured the couple's quest at the beginning of April.
In 2009 the adventurous couple stood on the summit of Everest for the first time after climbing the south side from Nepal and are now attempting to scale the north side in Tibet, hoping to reach it by the end of May.
The seasoned climbers first attempted the north side of the mountain in 2005 but had to abandon it when Noel experienced retinal haemorrhaging in his eyes at 7,000 metres.
And this time they will be carrying with them the ashes of their beloved pet dog Babu - who they bought just after their last attempt at climbing Everest from Tibet.
Babu ran and trained in the mountains with Lynne and Noel throughout his 10 1/2 years, before passing away in December 2015.
And if the gruelling physical challenge wasn't enough - they are also documenting their journey for everyone following their expedition. Check out our gallery to see the incredibly pictures of their experience so far.
The couple, who now live in South Africa, left on April 18 and arrived at Everest Base Camp on April 21 where they provided their first update.
Lynne wrote how they would not be able to shower for at least four days in case they got a chill, so instead they had to opt for a baby wipe body shower instead.
They have documented their acclimatization process which involved them travelling to Intermediate Base Camp and back again.
The traditional Puja Ceremony was held at base camp to bless the expedition teams for a successful and safe ascent up Everest.
The local monk from the Rombuk monastery comes into Base Camp and performs this ceremony to request a safe passage for climbers on the mountain.
Posting on their Facebook page Lynne said whether it is your belief or not, in her opinion, if the Sherpa’s who have been climbing Everest for a lifetime believe in this blessing, then she is more than happy to take part in the process.
She said: "I found the ceremony very emotional with juniper and incense burning, it's hard not to be moved and think of the days ahead and the dangers of this very daunting mountain.”
On May 7 they finished their final acclimatization process and were resting up waiting for a suitable weather window to begin their summit.
They posted a video update from 7,000 metres above sea level.
They said: "We are still alive after two nights at 7,000 metres above sea lvel. This is the last part of our acclimitization. We are a bit short of breath up here and even the smallest things can wear you out. We are heading down today to advanced base camp and then down to middle camp.
"We have about two hours work heading down today no climbing up today. which I'm delighted about, no climbing up today. So far so good."
