are so many, and come so rapidly, one after another, that it's easy to become a little blasé about them.

I'm probably right at the head of the queue where that's concerned, but just occasionally something happens that brings home to me how astonishing some of our advances are. That happened just now, when I read about how Nasa's Curiosity Mars rover has calmly drilled a hole in a rock on a planet that's currently around 60 million miles from earth, and sent us a high-definition image of the hole to prove it.

The technologies leading up to this seemingly simple act are even more amazing when you remember that it is just over 100 years since the first flight of a heavier than air machine.

The dust from the hole is now being analysed, and soon we'll know how that rock was formed, and when.

Something to wonder at over the Sunday morning bacon and eggs.

"It is amazing what they can do now and yet they still can't cure cancer."

That's not true.

Some forms of cancer such as acute leukemia and some types of lymphoma can be curable with chemotherapy, and certain lymphomas, such as Hodgkin's disease, are cured with radiotherapy. Other common cancers such as colon cancer, pancreatic cancer, breast cancer, lung cancer, and prostate cancer are all curable, but only if they are caught in one of the first two stages.

Advances in cancer treatments over the past 30 years have been amazing, and I have no doubt that equally amazing advances will be made in the next 30.

As FE points out, there have been a considerable number of advances in the methods of Treating Cancer.

However, a common misconception is still prevalent which needs to be cleared up.

Cancer is not a "Single" Condition. ~~~~~ It is a multitude of dfferent Conditions, each requiring to be addressed separately.

The escape velocity of Mars will be akin [slightly less] to that of the Earth's ... so a substantially powerful rocket system would be required for a homeward journey back to Earth, from the surface of Mars.

"The escape velocity of Mars will be akin [slightly less] to that of the Earth's"

Actually it's less than half. The escape velocity for earth is 11.2 kilometres per second, and that of Mars is 5 kilometres per second.

Forum Editor - a hop, skip and a jump would get you off [escape] from either of these 2 little moons of Mars:-

... as long as you've not got a dodgy foot [or knee], of course!
