Launch, Land, Repeat

Am I the only one finding the last 2 BO videos highly disingenuous ?<p>As mentioned numerous times, there&#x27;s the whole &quot;reaching space&quot; vs &quot;going into orbit&quot; before landing.<p>More important to me is the fact that SpaceX is streaming its different tries in _live_, taking the risk of crashing the rocket out in the open. How many vehicles did BO lose before achieving a vertical landing ?<p>Oh, and what about the fact that they have total control on the location and time of the launch ? Meaning they basically control weather to an accuracy no one launching anything useful into space has. For example, last failed SpaceX landing was officially linked to fog icing the leg locks. That&#x27;s not going to happen if you launch on a clear day from the desert.<p>These are more comparable to the Grasshoper tries than to anything SpaceX has done recently : no horizontal speed, full weather control, no reporting on failed attempts, very limited weight. Even the last grasshoper video seemed to have more side winds that had to be countered than this 100k altitude video.<p>Even the format of the video itself screams &quot;vaporware&quot; to me. It looks like a trailer for a bad action movie, where some spacey something goes to space, separates and lands back in 15 seconds. When the grasshoper videos left me in awe, looping over them 5 times in a row, the BO ones just make me feel like they sh&#x2F;could end with some sexual innuendo over their big rocket

Honestly just roll my eyes now at these pissing contest blogposts from Bezos. He does his team a disservice by suggesting that what they are achieving is actually more advanced than what SpaceX has done - it all looks like the approach the Soviets took in trumpeting various &quot;firsts&quot; in space in the 60s as the US methodically built capability far beyond what the Russians could sustain.<p>I am impressed by both companies&#x27; ambition, and SpaceX clearly has both the time and money advantage over Blue Origin. Let your accomplishments speak for themselves.

Impressive, but one important difference with the SpaceX rockets is that this rocket only goes up to space but it doesn&#x27;t put satellites in orbit.<p>Form: <a href="https:&#x2F;&#x2F;what-if.xkcd.com&#x2F;58&#x2F;" rel="nofollow">https:&#x2F;&#x2F;what-if.xkcd.com&#x2F;58&#x2F;</a><p>&gt; <i>The reason it&#x27;s hard to get to orbit isn&#x27;t that space is high up. It&#x27;s hard to get to orbit because you have to go so fast. </i>

I like it -- we&#x27;re starting a 21st century space race between corporations rather than nations.

This is amazing, and a pretty amazing feat that we are taking for granted. Space is super super tough, the complex coordination of manufacturing something like this is being totally written off by many, but I assure you it is non trivial.<p>A popular sentiment in that industry is that rocketry is like writing software composed of many modules and testing each module separately on mac, then deploying the entire build on linux. If it doesn&#x27;t work, you don&#x27;t just back out the conversion error or stray quotes you left in, your rocket explodes.<p>The engineering spend alone is massive, as is the damage to the company when a failure is syndicated across youtube. Taking big risks is something we should be promoting.<p>We are in a technological renaissance and it starts with lowering launch costs to achieve realtime LEO satellite blanketing and distributed communication channels to connect to the other fucking 3 billion people without internet. Bezos is accomplishing something great, and we don&#x27;t need to qualify that statement.<p>He and Musk are definitively the Jobs and Gates of the 21st century if you want to use the obvious cliche.<p>What Gates did. What Jobs accomplished. It was pretty fucking powerful. Musk and Bezos are sort of doing that, except both are working in at least 3 industries at that same scale.<p>I wish Blue Origin, Sierra Nevada, Firefly and all the other people in new space well. Nano-sats will provide realtime insight to the earth, people will be able to own a satellite in ~5-10 years because of these advancements.<p>this is good for <i>all</i> of us, and the only negative thing to say about it is that for god sakes Jeff, that rocket does look a bit like a stubby penis.

SpaceX = Space launch.<p>Blue Origin = Rollercoaster.<p>I really don&#x27;t see why these companies are competing. They are in totally different markets. Sure, there is some technological crossover in that they both use rockets, but this is like comparing a prius to a locomotive.

It sounds like Blue Origin rockets are only capable of sending payloads to space for just an instant, before gravity pulls them back down to earth. They&#x27;re nowhere near close to capable of putting anything into orbit.<p>Is that correct? If so, what are they good for?

&quot;Our vision: millions of people working and living in space&quot;<p>When you have only a few seconds above the &quot;official&quot; space altitude on a parabolic trajectory, I wouldn&#x27;t say&quot; working and living in space&quot;, and specially not &quot;millions&quot; at the same time..<p>Is it me or this is primarily a pitch video ?

I think its great that New Shepard is coming along, I don&#x27;t get how Bezos feels he is helping his cause when he says &quot;people living and working in space.&quot; when he doesn&#x27;t come close reaching orbit. The difference between an orbital mission and a sounding rocket.<p>Now, that he is getting closer to having tourist flights outside the atmosphere than Virgin Galactic? That is pretty cool and a fair comparison. Being able to out execute Burt Rutan? That counts for a lot, but don&#x27;t try to compare yourself to SpaceX until you&#x27;re putting things into LEO and getting back the hardware to use again.

Here is an animated video that shows what space tourism will be like. You will be in space for a few minutes. the view of the world from space will be amazing. plus you will be weightless. not sure how long you will be up there or the cost but it looks awesome.<p><a href="https:&#x2F;&#x2F;www.blueorigin.com&#x2F;astronaut-experience#youtube-YJhymiZjqc" rel="nofollow">https:&#x2F;&#x2F;www.blueorigin.com&#x2F;astronaut-experience#youtube-YJhy...</a>

I wonder SpaceX opening an office in Seattle was just to make it easier to hire away engineers from Bezos?
sailfast超过 9 年前
This looks like a very complicated engineering achievement that undoubtedly will lead to advances in space travel and tourism.<p>That said, I didn&#x27;t get to watch the launch and join in its success or failure, so I&#x27;m finding it difficult to actually care as much as other launches.

Is there a significance for ~100km? Is this, roughly speaking, space -- where the atmosphere is so thin to be almost negligible? Clearly atmosphere thins gradually so how do we define where space starts? Is the significance of ~100km something to do with the effects of gravity at that altitude from the Earth&#x27;s surface? Does ~100km give you weightlessness? Or is Blue Origin going up to ~100km because it&#x27;s a nice round number that is roughly (whatever that means) in space. But aren&#x27;t kilometres completely arbitrary?<p>Also, can people please stop knocking Blue Origin. We get it at this point, okay? I&#x27;m a huge fan of SpaceX and Elon Musk but does Blue Origin have to lose for SpaceX to win? No. There&#x27;s nothing in this post from Bezos bashing SpaceX as far as I can see. There&#x27;s simply saying, look, we did it again with the same refurbished rocket. Good on them. May they do it again and again. And so may SpaceX. The next space race is on, happy days!

Is Blue Origin landing a booster that SpaceX is letting crash? Would their forces combined result in total re-use? I&#x27;m not sure what all the parts and roles are. Sorry for the dumb question.

What I am really looking forward in the bigger rocket from Blue Origin that will be able to achieve orbital velocity.

This is awesome. A great compliment to the work SpaceX is doing. To put it in perspective this rocket went about 100x as high as an average international airline flight but would still need to go about 4000x as far to reach the moon. Not sure about the 3 mile per hour impact with the ground on my way home from work. I suppose with a nice soft seat it would be fine but by the time United Airlines gets done with it you&#x27;ll be packed in like an NYC cross town bus with a seat just as hard.<p>edit: got my facts straight

One would think that using fuel to touch-down slowly is wasting fuel since they could use some kind of capture scheme with a parachute instead. I&#x27;ve read many times that the weight of the fuel is a big problem in spacecraft.
