The recent Falcon Heavy launch was delayed a day due to upper level winds -- windshear can cause a long, skinny tube like the Falcon to crumple/snap. Flying above clouds does nothing to avoid this, although the max altitude of the Stratolaunch should put a rocket just above these, assuming it can actually reach that.
OTOH, planes have air-breathing engines that run on relatively cheaper fuel, so have a higher ISP and lower cost/KG. The real question is how heavy of rockets it can carry and if it'd end up being cheaper to do that than just using a bigger rocket. The plane will pretty much necessitate a flat launch trajectory, unless it does a steep climb just prior to release.
Section 230 is about legal liability. If someone infected with measles wants to sue Facebook in civil court because they didn't shut down antivaxx posts, Section 230 protects them from that. If someone posts hate speech/death threats/whatever to Facebook, that prevents Facebook from being legally liable for hosting it. It's not about preventing the Attorney General from fining Facebook or throwing Zuck in jail over posts some rando made on Facebook.
Google would be a-ok with Section 230 getting the axe. That'd mean that advertisers and other corporate partners would have an even greater portion of the Internet's presence, on Youtube and Google Search. They'd heavily restrict who can post to Youtube, saving them tons of money, and being able to blame the government, just like how Microsoft was able to blame the government when they were allowed/forced to turn over data stored in other countries. Twitter and Reddit would be reduced to verified accounts, with so few posts it's feasible to have moderators pre-approve all posts. Twitter is about the only social media site that'd be able to survive this transition, as it could easily turn into a 'read-only' website for the plebes to read announcements by VIPs. Twitch would be reduced to a couple dozen known quantities being streamed, everyone else being muted and only allowed to stream whitelisted unmodded games.
It's not just the USA talking about this -- New Zealand, Australia and the UK are also talking about it. Just waiting for the fifth eye now...
333,519 of them were iPhones deemed by the company to be "reusable." And of those, 33,000 of them were iCloud locked... the Wireless Alliance found that more than 90 percent of them had not been reported lost or stolen
The prior Crew Demo 1 mission had more impact on the ISS than this flight did. Sure, if we were still hoisting ISS parts into orbit, then the Falcon Heavy might be relevant. The Crew Dragon 2 capsule ends dependence on Soyuz, assuming it passes its next tests ok (which it should).
If anything, the Falcon Heavy ends dependence on the Delta IV Heavy and Atlas V, which have a ~18 month lead time due to how long it takes to build a new one just for your launch.
I'd probably rather risk doing a few years in a Swedish prison than go into self-imposed exile in an embassy for several years. So he probably was actually worried of deportation to a black site.
The case was suspended, since he was inaccessible. The one who did this indicated that they could quickly reopen the case if he were to ever become available. It's as meaningful as reprogramming your ICBM targeting computer to no longer point at your enemy.
Microbes stuck to surfaces wouldn't all be pushed out into the vacuum, because there's no air in-between them and the surface, and they may hide in a crevice/scratch that air rushes past. Furthermore, there are plenty of surfaces that move and are only exposed when in certain positions (say, a headphone jack when not plugged in).
A more effective solution might be to have moveable radiation shielding, have the crew move to a shielded section and fry the other sections enough to kill the microbes, then repeat for the section they were holed up in.
The idea that the new testament overturns the old testament is controversial to this day. In particular, a quote from Jesus contradicts that idea: (para.) "I have come not to overturn the old teachings, but to fulfill them."
The average Christian is miles away from what modern Biblical scholars believe; or any Biblical scholars, for that matter.
Interestingly, OneWeb has bad blood with SpaceX and refuses to use their rockets to get their own satellites up. I wonder if something similar might happen now with Amazon.
The question is: once you have full reusability, how do you cut rocket launch costs further? New engines/fuels/drop rockets... BFR is only 2.5 of the 4 orders of magnitude cost reduction that Musk wants.
It'd help an interstellar spaceship if it were doing a propulsive landing on a planet with atmosphere. But I concede it wouldn't be an important consideration for a first trip when we know nothing about what's there aside from maybe a couple gas giants.
If the Sun is inbetween Earth and and the starship, then that'd make telemetry a problem. So we'd want relays in other orbits/lagrange points/interstellar space. If you mean the signal being too weak, then you'd want to use auto-tracking line-of-sight communications (e.g. lasers).
Unless aiming for a flyby, I imagine the 'slowing down' part would be built into the mission specs, just save ~1/3 of your fuel for slowing at the destination. Solar sails can be turned around so that the target star slows them (although AFAIK this has never been demonstrated.)
I'd be more worried about miscalculating the relative velocity of our solar system and the target star, and ending up where the star was a few years ago, too far away from it to capture decent images.

Walled garden in one ecosystem, pervasive spying in the other. Hmm...

Strike that, seems Canada is getting in on the act too.

Project Zero thanked them for their efforts and promised a fix in the next build.

It doesn't, but 'sample error' does.
It was written by a muppet, obviously.
Skynet's efforts at character assassination were once again successful.
Everything is going according to plan.
You've been here 20 years, so clearly you deserve to be modded up for your opinion.
Oh, wait...
