After resuming drilling in Seattle — and only going four feet — Bertha has been stopped again.

After resuming drilling in Seattle — and only going four feet — Bertha has been stopped again.

High temperatures near the machine’s cutting face prompted contractors to stop mining after the drill advanced a total of 4 feet in test runs Tuesday and Wednesday. And that ended Bertha’s attempt to resume mining after an eight-week layoff.

The earlier stoppage remains unexplained. They found some concrete chunks and steel pipe sections in the way, but nothing that could have explained why the drill was blocked. Now the high temperatures pose a more significant problem, as they suggest there is something technical wrong with the giant drill.

A new harvest of vegetables in space!

A new harvest of vegetables in space!

Notice that this research is a partnership of the Russians and an American university. NASA is not included. When I wrote about this subject for Air & Space a few years ago, the American researcher explained that there was too much bureaucracy working with NASA. Moreover, the Russians were much more knowledgeable about crop research in space, as they had been doing it for decades already on their Salyut and Mir stations.

What life has been like for one engineer who works at SpaceX.

What life has been like for one engineer who works at SpaceX.

Key quote:

According to Pearce, the best and the worst things about working for Musk are actually the same. “He doesn’t feel the need to make reasonable requests,” Pearce says. “The whole idea of SpaceX is not reasonable. The idea that a dot-com millionaire could take [US] $100 million and start a rocket company that within 13 years would be taking supplies to the International Space Station, that’s on track to take crew to the International Space Station — that’s not reasonable.”

But SpaceX did it.

Better medicine through engineering

3:26 pm

For me, the last eight months have been very interesting when it comes to medical treatment. I have had my left hand rebuilt to eliminate chronic pain, I had my heart inspected to make sure it was working properly, and this week I had the retina in my right eye re-attached using some very clever engineering.

For once, this essay will not be about the politics of medicine and the disaster of Obamacare, which is still ongoing. Instead, I will outline how freedom and human creativity has now made possible a whole range of modern medical techniques that are either improving the quality of life for patients or literally saving their lives.

The National Science Foundation wants to get rid of some of its older big telescopes, and you can buy them!

The National Science Foundation wants to get rid of some of its older big telescopes, and you can buy them!

We are not talking small here. The biggest is the Green Bank Radio Telescope in West Virginia, which though only fourteen years old is unable to compete scientificially with the new large radio telescope arrays. In truth, when it was mostly built to satisfy the pork ambitions of the late Democratic Senator Robert Byrd.
