Just the opposite. Manipulation requires effort.

I'm not sure what improvement they're anticipating over current levels, but the newer rocket engines are much simpler than the previous version, and more powerful & efficient. I think with the Falcon series, it's the turn-around time that can be most improved. AIUI, the Falcon core can do a controlled return & landing for some orbits but not for others. When Starship gets going properly some time this year, the aim is for full reusability, but I'd expect a few failures before all the bugs are sorted out.Not sure how much more they can squeeze out. Perhaps a factor of 2 or 3 (which would be fantastic, but still not "cheap").
The smaller, Falcon9 is basically fully reusable and the same rocket is used as a reusable booster on the Falcon Heavy. (I'm sure they'd like to extend the number trips made by each rocket and reduce ground turn around time and cost, but I suspect we are a ways a way from when rocket reuse looks like the check process used between car rentals. They may already be ahead of the Space Shuttle program in terms of require inter-flight maintenance. ) The manned capsule is also multi-mission.
The core stage of the Falcon Heavy is a bit harder to deal with given how high up and down range it must go. I don't know their plans but perhaps they want to replace it largely with Starship launches using its Superheavy booster. We'll see how that works out.
(I continue this sub-thread, since rocketry is at least board on-topic.)
Exactly so. Your statement supports my contention that "The abusive use of the "Survival of the fittest" meme to justify indifference to human suffering is as unattractive today as it was when first introduced."A lot of downs syndrome babies are aborted because there are doctors who feel they do not have the right to live.
Many hundreds of times I have tried to explain that to people. Sometimes they get it, sometimes they don't. It can be very scary when we realize that people have to live up to the standards they set for others. God is going to hold them accountable.Which to me means, that when you're part of the problem, it's easier just to blame someone else.
There is going to be a bit of a delay. China is threatening to blow them out of their obit into a lot of pieces. So Musk is working on a "shield" to protect them. I use to talk to my older son about this all the time. He was an electronic engineer and said it was pretty easy to defend against these sorts of attacks. Even in Martial Arts, it is pretty easy to defend yourself by deflecting the attack of an aggressor without doing any harm. Although they may harm themselves. They teach that in Basic in the Army. It is your choice, you can just disarm them. Or you can disarm them and mess them up pretty good. Only they do it to themselves. Even my son had a training film where the instructor was 80 years old and he could still take on 5 of his student at the same time.When Starship gets going properly some time this year,
Some studies have reported that more than 90% of babies with Down Syndrome are aborted in some countries where prenatal testing is widely available, while in other countries the number is much lower. My brother is a specialist in Down Syndrome. So it is putting him out of a job.Exactly so.

Yeah, and curing cancer will put oncologists out of a job.Some studies have reported that more than 90% of babies with Down Syndrome are aborted in some countries where prenatal testing is widely available, while in other countries the number is much lower.

You seem to think you are disagreeing with something I said. I just see you making unrelated statements. Do continue if it feels satisfying.Some studies have reported that more than 90% of babies with Down Syndrome are aborted in some countries where prenatal testing is widely available, while in other countries the number is much lower. My brother is a specialist in Down Syndrome. So it is putting him out of a job.
I have always been this way. The doctor thought it was brain damage when I was in a coma but my brother said he has always been that way all his life. So there does not seem to be much anyone can do about it.I just see you making unrelated statements.
I was talking about Starship, not Starlink. It's Starlink that China sees as potentially threatening.There is going to be a bit of a delay. China is threatening to blow them out of their obit into a lot of pieces. So Musk is working on a "shield" to protect them.
There are shields for that. We have the technology to disable a car if we wanted to zap it's computer. But they do not want to let the genie out of the bottle or everyone would be doing it.They might be able to sabotage them electronically,
The problem is that you can't retrospectively shield a satellite, and LEO satellites like Starlink have a 5 year lifespan, so there's a minimum 5-year lag time between deciding to shield and having all satellites shielded (assuming you can launch the full complement within 5 years). But given the significant extra cost involved, you're unlikely to do it unless you're convinced there's a credible threat. So it's not an easy or a cheap decision to make.There are shields for that.

I doubt that will be a serious problem - Musk is already contracted to produce the secure StarShield system for the US military, so expect that technology to filter down into the standard Starlink as they begin to be replaced.I think the real problem Musk is going to have is people hacking his system to steal it for their use like GPS.
Yes, my older son was an electronic engineer. I use to talk to him a lot about building a shield to protect against E-bombs and he did not think it would be a problem. It is going to cost Musk some money to protect his interests but he does not seem to think it will be a problem. He is worried about AI though because it is so powerful.I doubt that will be a serious problem - Musk is already contracted to produce the secure StarShield system for the US military, so expect that technology to filter down into the standard Starlink as they begin to be replaced.

Thank you for sharing that. It will make it easier for me to absorb your posts. As I remarked, they are clear and informative, they just don't always seem to connect to the flow of the conversation.I have always been this way. The doctor thought it was brain damage when I was in a coma but my brother said he has always been that way all his life. So there does not seem to be much anyone can do about it.
I did take four teacher training classes at the Bible college so I could be more coherent and better communicate with people. A few more classes and I would qualify as a superintendent. Now I am letting the chatbots do more for me to organize my thoughts and make them easier for people to understand.
Originally, the Hubble Space Telescope was designed to operate for 15 years, but its longevity and continued success have led to several servicing missions, which have kept it operational for over 30 years. The latest and final servicing mission was carried out in 2009, and it is expected to continue operating until at least 2029, when its replacement, the James Webb Space Telescope, is expected to become operational.This makes me feel better about this orbital menace. The atmosphere will scrub them out of existence within a decade.
JWST is operational now.Originally, the Hubble Space Telescope was designed to operate for 15 years, but its longevity and continued success have led to several servicing missions, which have kept it operational for over 30 years.
