Which microbes should we bring to Mars?

…and how do we decide that? Is it even possible to “choose” exactly which bacteria, viruses, fungi and so on will accompany us to Mars? I don’t recall hearing much discussion about this and I’m curious. Is it possible, or even desirable, to try to stop certain microbes from gaining a foothold in a new Martian outpost?

Hydrogen Starship would've been an even bigger monster. Ultimately it lost out on the trade to Methane 🛰️

What are the bad things private space has introduced to the industry? Its not all roses and rainbows so I would like really honest answers here.

Lets answer this question in the context of these categories:


Economics in the nearby communities that host either the east or west space coast

Job market (private space)

Pay grades

Adjacent Opportunities (organizations, groups, public events, open houses)

Rocket enthusiasts

Curating new interests in space

Space junk


If no one can think of anything, I will follow up with one and you can bite on it. Please if answering something like x number of jobs have been added, please source and prove this.

Any idea why spaceflight rookie Zena Cardman is the CDR of Crew-9? Especially with Nick Hague (veteran of 2 flights) and Stephanie Wilson (veteran of 3 flights) on board?

Poll time - Which of these commercial space station designs do you like best?

I ran similar polls in August 2022 and in May 2023 to get an idea of what this community thinks of the current offering of private commercial space stations. Since then there have been some major changes such as Northrop Grumman’s proposed station being cancelled due to lack of private funding and HALO cost overruns.

Please provide your reasoning for you choice in the comments and even a ranking of the designs if you like.

For those unfamiliar with any of the designs below I have added in the basic specs(crew size, stated launch year, unique selling point) as well as including links to the videos put out by the companies building them and company websites with information on the designs.

Axiom Space Station Specs(based on when detached from ISS): Crew: 8 Launch year: 1st module to ISS in 2026 and will be independent from ISS before its decommissioning. USP: modules individually attached to ISS allowing for steady build up, inflatable module. Videos: https://youtu.be/vHMrYYIXxqE https://youtu.be/Mf7vPy_H94Q?si=X8OOH0b7LqoKzFGC Info: https://www.axiomspace.com/axiom-station https://www.seespacearena.com/

Orbital Reef Specs(Baseline - Growth configurations): Crew: 10 - up to 40 Launch year: 2027 - 2030s(TBD) USP: flexible growth of station, inflatable modules, large diameter modules(9m or 11m), single person spacecraft. Videos: https://youtu.be/SC3ooNXfcGE https://youtu.be/xfBex09190M?si=Dpo-qPAP6gB97cBy Info: https://www.blueorigin.com/destinations https://www.blueorigin.com/news/orbital-reef-commercial-space-station/ https://www.sierraspace.com/space-destinations/ https://genesisesi.com/projects/sps-orbital-reef/

Starlab Specs(current design is based on Airbus LOOP): Crew: 4 Launch year: 2028 USP: Artificial gravity, large diameter station (8m) single launch to deploy station. Video: https://youtu.be/RXfNJdpb8wU Info: https://starlab-space.com/ https://www.airbus.com/en/airbus-loop

Haven-1 Specs: Crew: 4 Launch year: 2025 USP: Lunar artificial gravity, single launch to deploy space station. Video: https://youtu.be/fwR5sSOSYhk?si=wruB-MJffLhjs8br Info: https://www.vastspace.com/ https://www.spacex.com/updates/

ThinkPlatform-3 Specs: Crew: 40 Launch year: TBD USP: large diameter station(20m), single launch to deploy space station. Video: https://youtu.be/Z3GBE_NS6Y8?si=u3U5WFt1QhLZcwqe Info: https://thinkorbital.com/space-infrastructure/

Also below is a great comparison video of Orbital Reef, Starlab, Axiom Space Station and a SpaceX Starship space station concept.

Spaceflight Communications Chain of Command

Hello r/spaceflight. I'm doing research on Safety-II and Resilience Engineering for commerical Human spaceflight and currently am looking at risk control and management in current spaceflight industry. At this time, I am specifically looking for the chain of command for spaceflight communications. For example, with aviation, you have various controllers: ground, tower, departure, approach, all depending on which phase of flight you are in.

What I'm trying to figure out is who do the astronauts/pilots talk to during the various phases of spaceflight (launch, cruise, encounter, no line of sight {ex: behind a planetary body}, landing). I've taken a look at NASAs spaceflight texts, and have a general overview, but not quite specific enough.

Any resources or fingers pointing me in the right directions would be appreciated.

Starship Centaur?

I had recently watched a video about a proposed interim stage for the space shuttle to bring payloads to higher energy orbits called the Shuttle Centaur or Centaur G. That logic would probably apply to Starship, since it also has to carry the weight of all that stainless steel. So, what if there was a 3rd stage that can take lighter payloads to high energy orbits in a single mission? It would save a lot of money and time since you dont need to launch seperate tankers.

Pilot license + career questions!

Im a 24yo female graduating from my masters BME program this spring and am currently unemployed. I have spare time so my family says they will pay for my pilots license which I could complete upon my graduation. Although, my long term goal is to work in Mission Control for crewed missions as a flight controller. Is it unnecessary to obtain my pilots license? Is having this certificate useful in anyway as an engineer?

I do not have internships under my belt but 2 research experiences (one ongoing and related to astronauts). I want this license to add edge. FYI- I went the BME route bc I like to work with people, I have the option of going to med school later (for space), and want to work with crewed missions.

Some other hobbies that have interested me, regardless of my job, that I want to obtain are my skydiving and scuba certifications.. are these beneficial at all to a job in Mission Control at NASA?

..or do you have any job suggestions from this chaotic list that I drew up?
