Sorry, I wasn’t exactly bee-ing nice last night.
SLS takes off from Earth, but that doesn’t mean successor Hydrogen rockets will, and that doesn’t mean that the Hydrogen has to come from Earth once space infrastructure is in place.
By tackling challenges with hydrogen storage and transport, SLS is an investment in our future and in other parts of the green hydrogen economy. Hydrogen is very small and leaks. This is one of the biggest technical challenges wherever hydrogen is used. NASA overcomes technical and engineering challenges on large scales. Investment in hydrogen rockets is investment in green energy for the future.
Major benefits of NASA and space travel come from challenging ourselves to do things the “right” and “hard” way. Tackling these hard challenges provides technology that improves life and jumpstarts the economy across many sectors.
Going cheap-and-dirty and cutting corners is potentially dangerous for those using the cheap rockets, uses up underground organic reserves that are vital to ecosystems, and promotes a “throwaway” culture.
I should have challenged myself to reply to you the “right” and “hard” way instead of being dismissive and rude.
The good news about SLS is that it’s not burning fracked natural gas like Elon’s rockets… it’s burning Hydrogen that was produced from fracked natural gas. It’s not green now, but it has the potential to be in the future. Cryogenic H2 requires some expense compared to cheap-and-dirty methylox.
The other advantage of SLS is that these rockets are owned by the people, not private companies. If we want an equitable future in space, we need NASA rockets. Right now the SLS is that rocket.
It’s the new space race. Japan, Russia, Israel, and India were racing to be country 4 on the moon after USSR, USA, and China. India won the number 4 slot, and now the other three are shooting for 5. With SLS and Artemis paving the way for a lunar colony, everyone wants to be able to participate.
What do you want that to look like?
I agree that what you propose in abstract would be a good thing! How do we do it?
Would you like to see people posting pictures and stories of ways that they have mitigated the climate impacts of their own lives? Kind of like /r/zerowaste? This would be cool and good! But real change comes not at the individual level, it comes from organizing communities at the local level.
Maybe you’d like to see more of that local-level organizing happening here? Well, this isn’t a local community. Where and how could such a disparate group of individuals make meaningful change?
Perhaps you’d like to see a meeting space where local groups communicate and coordinate larger-scale action? Cool! However, we kind of need local groups to get organized before that’s really possible. Don’t forget that organizing in a public and easily-scrapable space makes it easy for those we are organizing against to know our plans and work to counter them. However, having an easily accessible public face for people to get started and involved is also important!
Lemmy is a website for sharing and discussing news and memes. If there are ideas you want to spread or need you want to share, do it here. If you think that people are approaching a problem wrong, make a meme pointing it out. If you want to spread an interesting perspective, share it here for discussion. If you are looking for political action or to make meaningful change, find allies in your local community.
Lemmy is a place for ideas, not action. If you want action, find some comrades.
Once you have a local group taking action and making changes, share it here to inspire and support others doing the same.
Nice to meet everyone!
I love space, the stars, and observing our place in the universe.
There is little that I love more than going outside and keeping track of our celestial neighborhood. I spent much of my adolescence nocturnal to avoid the heat and people of Florida. I'm still rather nocturnal.
For my research I focus on our solar system, the outer solar system in particular. I'm working on a PhD thesis studying Saturn's carbon cycle using data from the Cassini mission (2004-2017). I am reading a lot about our current state of knowledge for Uranus in preparation for the next major mission which I am hoping will provide a career trajectory for me if/when Congress starts funding it next year as promised.
The biggest thing that we know about the outer solar system is that we really don't know that much about it. The past few decades have shattered our previous models of the outer solar system, and the scientific community still has not settled on a new paradigm. One thing is obvious, however: the planet that we know the least about is Uranus, and until we have better data it's nearly impossible to narrow down the list of potential theories. In other words, these theories require better constraints on the properties of Uranus to be tested (Neptune is a close-ish second). Yes, I want to probe Uranus. It's due for a check-up. I believe that the outer solar system has an under-appreciated and under-researched astrobiological potential. The elements of life (HCNOPS) are much more abundant in the outer solar system than the inner solar system. I am fascinated that our models of Uranus are so unconstrained that it is still possible that Uranus has an ocean whose surface is buried under all of those clouds we can't see past. Clouds of CH4, NH3, H2S, PH3, H2O; clouds of the simplest biological precursor molecules: the volatile ices. We simply don't know what's going on out there, and we have poor constraints on the possibilities.
I am intersex and grew up in Florida. I have since escaped, if only just barely with my life and sanity. I've been taught about the many diverse carpentry techniques that American slaveowners allowed their slaves to practice, and that such skilled and creative labor can only occur under humane and fulfilling conditions. I've been taught that Woodrow Wilson was a great progressive devoted to civil rights who could have prevented WWII if people took him more seriously. I'm sure I've been taught many other things that need correction, but which I have yet to identify. I'm eager to learn and be corrected. My 11th grade US history class was taught under a 30 foot Gadsden flag that blocked the southern-facing windows so that it was backlit by the Florida sun. I am a socialist with a strong rebellious streak. I tend to hold unusual positions: rebelling against misinformation can lead you down strange paths to find the truth. I believe that non-standard interpretations of available data (when done in good faith, and when new data is welcomed to update or challenge these interpretations) are a healthy and important part of maintaining a diversity of viewpoints and keeping a perspective on the subjectivity of truth.
I am a big supporter of freedom and liberty, in software and in politics. I see computers as extensions of our brains, and the software that connects us as a new iteration of social institution connecting our minds and ideas. I believe that our minds deserve a certain amount of freedom and privacy. I believe that we should have the right to decide how our minds work and interact with the great internetworked collaboration of minds. We have a right to know how our minds make decisions, who our minds are talking to, and who is reading our minds. I am a big supporter of free/libre software, gnu+linux operating systems, and free and respectful means of communication and collaboration. We deserve to communicate using media that respect the users. If a platform does not respect its users, its users will not respect each other.
I see here a community that claims to be based on respect. I have been lurking for several months without an account. I am satisfied enough with that claim to make an account. I hope to get to know you people better; I hope to learn and discuss current events together, and I hope to share cool developments in our understanding of the outer solar system as they arise.
