One small step

The Eagle landed 49 years ago today, and two humans walked on a celestial body for the first time.

I have a fleeting, four-year-old’s memory of my dad waking me up (I must have been napping, as we were in CDT) to watch the moon landing. I don’t remember anything about the landing itself, just my dad waking me to see it. But that’s special enough, I think.

Here’s a nifty 360 of the interior of the Command Module that carried Neil Armstrong, Buzz Aldrin, and Michael Collins to the moon that day.

Apollo source code

This article is actually a couple years old. But if you haven’t seen it, it’s a fun read.

Keep in mind that this software was literally woven into the Apollo Guidance Computer’s (ACG’s) memory by hand. Wire by wire, the 0’s and 1’s were stitched together to get us to the Moon.

Programmers, at least the ones I like to hang out with, have always had a sense of humor in the commenting of their code. It’s nice to see the programming team for Apollo was no exception.

Mariner 4

Mariner 4 was the first successful flyby of Mars. On this day in 1965, it made its closest approach and sent the first closeup images of the surface. These were also the first closeup images ever returned of another planet.

 

Learning from falling

“Part of the reason for the clumsiness is that, while you might weigh less on the Moon, your mass stays the same – and therefore inertia, which is a body’s resistance to changes in motion and is related to mass, not weight, also stays the same.”

First Man

A biopic of Neil Armstrong is coming in October, called “First Man”. It looks like the creative team is doing everything right. This could be really good.

“Jim and I have been spending a lot of time putting together an annotated script,” said Singer. “This is a book that will be published with the movie, and not only will it showcase beautiful stills from the film, which does look gorgeous, but beyond that we want to be very clear about what we fictionalized and when we diverged why it was we made that choice.”

Regarding Opportunity

The Opportunity rover has been quiet since this dust storm began. In this video, researchers discuss just how amazingly successful Opportunity has been.

We have an obligation

“Colonizing other planets will be a multicentury effort. Nobody alive today will see the end of this project. But, in a way, that’s really cool. It forces us to be farsighted, to take the long view.”

A short article that includes a longer podcast. Both are worth the time.

Dust storm

The dust storm on Mars is a global weather event.

“The last dust storm on Mars to go global occurred in 2007, five years before the Curiosity rover landed at its Gale Crater site, according to officials with NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.”
