Elon Musk’s Reddit AMA: Mars mission, upgrades to Falcon 9 and more

Published

on

Yesterday, Elon Musk oh-so-kindly reached out on reddit to curious minds in an “Ask Me Anything” (AMA) session as a follow up to his September 27, 2016 talk at the 67th International Astronautical Congress in Guadalajara, Mexico.

Thousands of questions were put forth by AMA contributors, and he provided 15 answers in true, Elon fashion. By that I mean taking fairly complicated questions and answering them in ways that make the original questions more understandable for the layperson (layperson = me). Also, one word responses to two-paragraph long questions.

General Outline of AMA Topics

Elon couldn’t put every inquiry to rest, but he did provide some interesting things to chew over. The audience, of course, actively participated every step of the way. Among the topics, there was…

  • Discussion on the types of power to be used for energy in the initial base of operations on Mars: Bets were on solar, doubts were on nuclear, and Elon seemed to play the methane card by referencing the Sabatier Reaction;
  • A clarification on upgrades to the Falcon 9, including a new naming scheme that doesn’t exactly coincide with the current semi-scheme;
  • A broad outline of steps planned for setting up the initial Martian base, Elon referring to it as “Mars Base Alpha”;
  • Discussion on the technical clarifications, details, and priorities for actualizing the missions, including perhaps even changing the name of the rocket…again.

Oh and sadly, no details on any fantastic spray parks or coffee bars in the crew cabin. We’ll have to wait a “year or two” before knowing what’s actually going to go inside the thing. He did mention geodesic domes and underground tunnels for “city” considerations, though!

Top Takeaways (IMO)

While Elon’s remarks definitely set some mental wheels in motion, these were my top takeaways:

  • Elon believes that the final Falcon 9 booster will be able to be reused indefinitely, production on that version to start in about three months;
  • Early Mars missions will be cargo-centric, twelve-passenger crews assumed;
  • The transport system booster should be able to withstand 30 to 50 g’s without breaking up (20 being the usual expected amount);
  • SpaceX will release mockups of the Mars spacecraft interior “in a year or two”;
  • The transport system booster will have an easier time landing than Falcon 9 due to mass ratio and density differences.

[Author’s note: It is going to be insane to watch those boosters land. Can you imagine the Saturn V landing itself? Wowza.]

Of course, my favorite part of reddit (no, really) is the humor. Here are a couple of funnies from this thread:

Final Words

Just a note of sympathy to anyone who’s ever felt a little overwhelmed by the technical knowledge discussions on the SpaceX subreddit (ahem, moi): I view it as akin to thinking you are a pretty knowledgeable cook and then watch an episode of Julia Child’s “The French Chef”. Just because you don’t know 182 ways to cook an egg doesn’t mean you’re not informed about cooking eggs nor are you disqualified from enjoying them. Some people just really really like knowing everything about eggs and can really get you thinking about eggs as multiple organ systems-turned gourmet meals instead of just the side that comes with your toast and home fries.

Anti-Tesla union leader ditches X, urges use of Threads instead

Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.

Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.

Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now. 

Anti-Tesla union leader exits X

In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.

“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.

Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant. 

“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.

IF Metall sees Threads as an X alternative

After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.

Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.

“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.

Elon Musk confirms SpaceX is not developing a phone

Despite many recent rumors and various reports, Elon Musk confirmed today that SpaceX is not developing a phone based on Starlink, not once, but twice.

Today’s report from Reuters cited people familiar with the matter and stated internal discussions have seen SpaceX executives mulling the idea of building a mobile device that would connect directly to the Starlink satellite constellation.

Musk did state in late January that SpaceX developing a phone was “not out of the question at some point.” However, He also said it would have to be a major difference from current phones, and would be optimized “purely for running max performance/watt neural nets.”

While Musk said it was not out of the question “at some point,” that does not mean it is currently a project SpaceX is working on. The CEO reaffirmed this point twice on X this afternoon.

Musk said, “Reuters lies relentlessly,” in one post. In the next, he explicitly stated, “We are not developing a phone.”

Musk has basically always maintained that SpaceX has too many things going on, denying that a phone would be in the realm of upcoming projects. There are too many things in the works for Musk’s space exploration company, most notably the recent merger with xAI.

SpaceX officially acquires xAI, merging rockets with AI expertise

A Starlink phone would be an excellent idea, especially considering that SpaceX operates 9,500 satellites, serving over 9 million users worldwide. 650 of those satellites are dedicated to the company’s direct-to-device initiative, which provides cellular coverage on a global scale.

Nevertheless, there is the potential that the Starlink phone eventually become a project SpaceX works on. However, it is not currently in the scope of what the company needs to develop, so things are more focused on that as of right now.

Tesla adds notable improvement to Dashcam feature

Tesla has added a notable improvement to its Dashcam feature after complaints from owners have pushed the company to make a drastic change.

Perhaps one of the biggest frustrations that Tesla owners have communicated regarding the Dashcam feature is the lack of ability to retain any more than 60 minutes of driving footage before it is overwritten.

It does not matter what size USB jump drive is plugged into the vehicle. 60 minutes is all it will hold until new footage takes over the old. This can cause some issues, especially if you were saving an impressive clip of Full Self-Driving or an incident on the road, which could be lost if new footage was recorded.

This has now been changed, as Tesla has shown in the Release Notes for an upcoming Software Update in China. It will likely expand to the U.S. market in the coming weeks, and was first noticed by NotaTeslaApp.

The release notes state:

“Dashcam Dynamic Recording Duration – The dashcam dynamically adjusts the recording duration based on the available storage capacity of the connected USB drive. For example, with a 128 GB USB drive, the maximum recording duration is approximately 3 hours; with a 1 TB or larger USB drive, it can reach up to 24 hours. This ensures that as much video as possible is retained for review before it gets overwritten.”

Tesla Adds Dynamic Recording

Instead of having a 60-minute cap, the new system will now go off the memory in the USB drive. This means with:

  • 128 GB Jump Drive – Up to Three Hours of Rolling Footage
  • 1TB Jump Drive – Up to 24 Hours of Rolling Footage

This is dependent on the amount of storage available on the jump drive, meaning that if there are other things saved on it, it will take away from the amount of footage that can be retained.

While the feature is just now making its way to employees in China, it will likely be at least several weeks before it makes its way to the U.S., but owners should definitely expect it in the coming months.

It will be a welcome feature, especially as there will now be more customization to the number of clips and their duration that can be stored.
