Pick of the Day

Spotlight, 9.00pm, BBC One

Here’s a Spotlight special subtitled A Contested Cemetery, which should offer some insight into the mindset of those living in the Six Counties, on both sides of the unionist and republican divide.

One hundred years after the partition of Ireland, former BBC NI political editor Mark Devenport explores where Northern Ireland is headed next.

He gets the views of the Prime Minister and Taoiseach, and also speaks to some of those who suffered during the contentious past.

Devenport also presents the results of an opinion poll assessing the views of the public, on both sides of the border, on what lies ahead.

Snackmasters: Shreddies, 9.00pm, Channel 4

Can’t remember the last time I had Shredded Wheat for breakfast. Must remedy that soon.

Anyway, this week Fred Sirieix sets two chefs to the near-impossible challenge of replicating a bowl of Shreddies.

Daniel Clifford and Claude Bosi (above, with Fred) both hold two Michelin stars. Both have also previously tried and failed to win a Snackmasters trophy, so this extremely difficult challenge is their chance to earn redemption.

They have three weeks to work out the factory processes that give Shreddies their famous lattice pattern and layered structure, before a cook-off where the factory judges will decide the winner.

Lego Masters USA, 9.00pm, E4

Looking for Life on Mars, 8.35pm, PBS America

Seeing as Earth is pretty much screwed and all of that . . .

Follow along as NASA launches the Mars 2020 Mission, perhaps the most ambitious hunt yet for signs of ancient life on Mars.

In February 2021, the spacecraft blazes into the Martian atmosphere at some 12,000 miles per hour and lowers the Perseverance Rover into the rocky Jezero Crater, home to a dried-up river delta scientists think could have harbored life.

Perseverance will comb the area for signs of life and collect samples for possible return to Earth.

Traveling onboard is a four-pound helicopter that will conduct a series of test flights - the first on another planet.

During its journey, Perseverance will also test technology designed to produce oxygen from the Martian atmosphere, in hopes that the gas could be used for fuel - or for humans to breathe - on future missions.

This documentary looks at how the drug company Insys Therapeutics profited from a fentanyl-based painkiller up to 100 times stronger than morphine that has been linked to hundreds of deaths.

In a bid to sell their product to as many patients as possible, the company mislead insurers, bribed doctors, and held contests for the sales team - the higher the prescription doses they got doctors to write, the larger the cash prize - despite the known danger to patients.

But their criminal scheme soon fell apart, and Insys became the first pharmaceutical company to have its top executives sentenced to prison time in connection with the opioid crisis.
