Houston, we have a problem

Some years ago, I posted the chart above, inspired by a classic XKCD cartoon. The infographic above shows the year of publication and of setting for several novels, plays, and films.

They fall into four groups. The top (white) section is literature set in our future. The upper grey section contains obsolete predictions – literature (like the book 1984) set in the future when it was written, but now set in our past. The centre grey section contains what XKCD calls “former period pieces” – literature (like Shakespeare’s Richard III) set in the past, but written closer to the setting than to our day. He points out that modern audiences may not realise “which parts were supposed to sound old.” The lower grey section contains literature (like Ivanhoe) set in the more distant past.

The movie Apollo 13 has now joined the “former period piece” category. Released in 1995, it described an event of 1970, 25 years in the past. But the ill-fated Apollo 13 mission of 11–17 April 1970 is now 51 years in the past; the movie is closer to the event than it is to us (although the phrase “Houston, we have a problem” – in real life, “Houston, we’ve had a problem” – has become part of the English language).

The image shows the real-life Apollo 13 Service Module, crippled by an explosion (left), together with a poster for the 1995 movie (right). Maybe it’s time to watch it again?

American Solar Challenge 2021

The American Solar Challenge is on again in July/August 2021, and will (per an ASC announcement) be following the Mountain Route on the Santa Fe Trail (see my previous post series). It is going to be a trifle warm.

The Mountain Route crosses the 7,840 ft (2,390 m) Raton Pass. The “big climb” at the 2018 American Solar Challenge (following the Oregon Trail) was 902 m in 35 km (2.6%). Starting from Trinidad, CO, the Raton Pass has a similar climb of 558 m in 22 km (2.5%), with a maximum grade of 6% on the steepest sections.
