Just to clarify - Orion is a partially reusable spaceship, developed by NASA with Lockheed Martin as the prime contractor, while SLS is a non-reusable launch vehicle, developed by NASA with Boeing as the largest contractor. SLS has been a poster child for cost overruns and delays - but so far is still intended to launch the crewed missions to Gateway, while it was never intended to launch the non-crewed Gateway launches.

NASA is looking at domestic commercial launchers powerful enough to reach lunar orbit for non-crewed elements of Gateway. As far as we know now of what will be available at the intended launch time in 2024, that will be SpaceX Falcon Heavy, ULA Vulcan, or Blue Origin New Glenn.
Falcon Heavy has the advantage that it's already in service. The other two are currently expected to make their maiden flights late this year.
It's possible that SpaceX could get Starship ready for launch by 2024 too, at their aggressive rate of development, which would be super cool, though it's early to order for launch services.
I'm super excited about returning people to the Moon. But Lunar Gateway is a bad mission architecture that really reduces the cost-effectiveness of returning to the Moon. It costs way more delta-v to reach the Gateway and then proceed to the lunar surface than just to go straight to the surface.

I really hope the new administration takes the opportunity to revise the mission architecture.
I've really come to admire Satya Nadella as a great CEO.

https://x-r.ai is applying AI to accelerate technology development - initially by applying AI to accelerate patent attorney work to reduce the time and resources required to resolve patent disputes and to shut down patent trolls.
We are developing an AI-powered work platform for patent attorneys to do all their work on which will replace the inefficient decades-old software they currently use, and make their work dramatically faster, more efficient, and more thorough. We have a handful of enterprise customers, who spend billion-dollar-scale per year on patents, in our private pro beta free trial, and they are getting rapidly more excited and asking us how quickly we can take more of their work and how soon we can expand coverage for their work in Europe and Asia.
We are targeting for x-r.ai to become the indispensable platform that all patent attorneys need to work competitively. Under our anti-troll license, any non-practicing entity and their outside law firms, and anyone who sues a startup for patent infringement and their outside law firms, will be banned from using x-r.ai, while startups sued for patent infringement and their outside law firms can use x-r.ai pro for free. Once we reach our target capabilities, it will be impossible for any patent attorney to work for a troll or for someone who sues a startup and ever be able to do their job cost-effectively again.
Help us revolutionize a giant market and lift a burden from the entire tech world by fixing patents with software.
I just started x-r.ai in April and we are still a very small team; all positions currently come with significant equity. We're based in beautiful, affordable Portland, Oregon and will also be doing in-person interviews in the Bay Area and Seattle/Redmond regularly, including in SF, SV, and Berkeley before and after the Deep RL bootcamp at Berkeley in late August. Work in-person in Portland at least occasionally is preferred, but we will evaluate case-by-case for the right people. Successful applicants should show evidence of high levels of drive, intelligence, and team fit, and interesting machine learning applications they've developed. So far our back-end is all python ML ecosystem but we're starting to get into lua as well. We're working to incorporate bleeding-edge deep learning architectures just released in the past few weeks, and to build a great AI engineering team ready to go after more verticals to accelerate development of new technology and to work toward artificial general intelligence. Apply via email on https://x-r.ai/careers and/or via scoutsavvy.co. Thanks much.
you can sign up for updates at http://x-r.ai & be notified when it launches. thanks.
http://x-r.ai/ is working on a patent attorney AI to automate a lot of patent attorney work to resolve patent disputes more quickly and cheaply.
Patent owners could use it too, but overall it would make invalidating patents and resolving patent disputes faster, easier, and cheaper.
Most patents are probably not valid, and most patents used in licensing offers / threats are probably not strong enough to avoid being invalidated or found not infringed if litigated, but the would-be licensor / troll counts on the threatened party to settle rather than pay millions of dollars for litigation.
While there aren't any easy tactical solutions and a policy fix is a dim hope, we should be able to at least partly solve the problem by training an AI to do automated and thorough prior art search and analysis relevant to a patent, so a lot of the legwork of a patent litigation threat becomes orders of magnitude faster and cheaper, and it becomes vastly easier and less intimidating for a trolling target to respond to a patent threat like this, and quickly get their focus and resources back to developing their technology. Software eats patent attorneys, and reduces the burden of patents on the technology community.
(disclaimers: I am a patent attorney and I'm currently working full-time on coding a patent search & analysis AI service, this is not legal advice, etc.)
Thanks, this looks great.

Looking for more, Paul. This from a Swiss news site says he had previously reported threats to the police, S3's data center was broken into and flooded with a fire hose, and that he remained in the hospital in serious condition with burns on his torso, arm, neck, and face, and would likely need transplants:

Swiss Space's web page's last press release is from 2014. There are threads on reddit and nasaspaceflight also just with speculation and no new info:

The breakout-success rate thus far is also skewed low by YC's growth curve. Things have still just begun.
This site was built as a side project by one guy who got it acquired by Planetary Resources.

Yes, brief sitting meditation and running meditation every day. There's evidence of physical and mental health benefits. It seems to help bring calmness, focus, and new ideas.
This stylometry analysis is 95% of a stylometry obfuscator/homogenizer.
More generalized, compassion and integrity seem to be in a positive feedback loop with drivers of technological and economic growth.
Gov't contracts are only something like one-third of SpaceX's revenues.
Yes -- even a breakeven on the satellite business that pays for more launches would be a big win, though I don't think SpaceX would do this without having good ideas for a niche with decent margins. But I wonder if this might mean foregoing potential future launch business with other satellite providers who would see SpaceX as a competitor instead of just launch service provider.
Me too. Add fires to energy consumption among the perverse results skeptics will harp on for the arbitrary constraints imposed by bitcoin.
Fitting that this comes just after Bezos also finally does something overtly public with Blue Origin (last month's ULA deal press conference), and that both efforts still seem, relative to time invested & return at stake, remarkably lame.
Progress on all fronts is driving the progress in exoplanets. The Kepler space telescope has been a huge driver, and Hubble, Spitzer, and big ground-based telescopes have played a big role; this new discovery is based on Hubble and Spitzer data runs plus comparison with Kepler data. Exoplanet search will take a giant leap with the planned launch of the TESS space telescope in 2017.
But this exoplanet was first discovered by a small network of at the time 6 extremely modest telescopes (just 110mm / ~4.3 inch objective diameter) automatically controlled by one Linux box in a project built by Gaspar Bakos when he was a student in Hungary.
Still, modern launch vehicle human ratings were only developed after the second Shuttle disaster, and are far beyond 1965 standards.

Falcon 9 v1.1 is almost certainly safer than the Titan II Gemini Launch Vehicle. As with prior Dragon flights, humans could have flown and been just fine.
It's Lockheed Martin that still insists on using imperial units instead of SI, even after the loss of mission that confusion caused in their work with metric-using JPL on Mars Climate Orbiter.
This 14-day interval between Falcon 9 launches was the fastest consecutive launch since Gemini 7 & 6A in December 4 & 15, 1965.
SpaceX plans to beat that record soon with launches a week apart becoming routine.
Given sama's enthusiasm for SpaceX, including as a "great example" in his blog post on the original new RFS, it seems unambitious for the RFS to mention space only in the context of robots and science.
"What comes after programming languages?"
Maybe somewhere in the direction Meteor and Light Table are heading?
"That's mostly a policy problem, not a technology problem."
That's the point though: the right insight might provide a technology solution to what everyone could only think of as a policy problem.
Landing is also a way less serious range safety concern than taking off because the rocket is essentially empty of fuel, rather than full of fuel.
