Camino del Rey
An evening pause:El Camino del Rey (The King’s Road) is a crumbling walkway high on the cliff walls of El Chorro canyon in Andalusia, Spain. The hike is not for the faint-hearted.

Spacewalk a complete success, old pump removed
Today’s spacewalk on ISS was a complete success. The astronauts successfully removed the failed coolant pump and made preparations to install the replacement pump on their next spacewalk.
NASA narrows asteroids to visit to three
NASA officials have reviewed the list of Near Earth Objects and found only three that meet all the constraints for a manned mission. Key quote:
Out of the 44 reachable asteroids, 27 were too small, and only 15 have orbits that allow for exploration between 2020 and 2050 — the timeframe NASA wants to pursue for NEO missions. The 180-day mission constraint further cuts the list to three.
It must also be noted that none of these asteroids are reachable without a heavy-lift rocket like the Ares V.
Rebuilding the American space program — the right way
In reading my post, Both for and against the Obama plan, reader Trent Waddington emailed me to say that this “is so fatalistic that it seems you don’t think it is worthwhile even spending a few minutes explaining why the policy is good. It’s easy to dismiss something a politician says as the stopped clock that is right twice a day. It’s harder to set aside your skepticism and explain why something is good policy.”
Trent is absolutely correct. What I wrote was very depressing and fatalistic. However, I think it very important to be coldly honest about things, no matter how bad they look. Once you’ve done that, you then have the right information necessary for fixing the situation.
My problem with most of the debate about the future space policy of the United States, — as well as innumerable other modern issues faced by our government — is that people don’t seem to want to face up to the reality of the problem. In the case of space and Obama, I doubt any advice, gentle or otherwise, is going to move him into putting forth a plan for NASA that has any realistic chance of getting passed by Congress. As I noted in a different post, he doesn’t play the game. He acts like the worst sort of autocrat, convinced that if he simply says what he wants to do, everyone must agree.
The reason the good part of his plan (commercial space) is not passing Congress is not because people think it is a bad idea. It is being rejected because » Read more

The great disconnect, part 2,345: In July, the first month of California’s fiscal year, the state spent $1 billion dollars more than had been forecast. Meanwhile, the state legislature has not yet passed a budget.
Diversifying your research portfolio
In this paper [pdf] adapted from a lecture he gave at an astronomy conference, Harvard researcher Abraham Loeb warns young scientists that their tendency today to take on safe research projects is unwise. Moreover, he notes the increasing “herd mentality” due to “stronger social pressure”, “more competition in the job market,” and the “growing fraction of observational and theoretical projects . . . done in large groups with rigid research agendas and tight schedules.” Key quote:
It is always prudent to allocate some limited resources to innovative ideas beyond any dogmatic “mainstream,” because even if only one out of a million such ideas bears fruit, it could transform our view of reality and justify the entire effort. This lesson is surprisingly unpopular in the current culture of funding agencies like NSF or NASA, which promote research with predictable and safe goals.
Hubble image of face-on galaxy
Another spectacular Hubble Space Telescope image was released today, showing a face-on spiral galaxy in the Coma cluster, located about 320 million light years away. Key quote:
The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes.
