    SpaceX plans to make January memorable with first Falcon Heavy launch

    SpaceX is planning to make January memorable for space enthusiasts with the first launch of its giant new rocket named the Falcon Heavy. And what is its cargo? Founder Elon Musk says it will be his original red Tesla roadster with a sound system blasting David Bowie's "Space Oddity."

    It's the kind of bold and eye-catching thing Musk is famous for, and it went from plan to reality in December while most of America was looking at Christmas trees, not the SpaceX facility at Cape Canaveral, Fla.

    During December, Musk released photos of the Falcon Heavy in the assembly building and of the Tesla being fitted into the fairing - or nosecone - of the rocket. Later photos showed the rocket vertical on the launch pad awaiting further tests.

    The Falcon Heavy would be a big step for SpaceX and for modern commercial space. It has 27 Falcon 9 engines - nine each on three core stages bolted together - and It will be able to lift more than twice as much as the next-largest commercial rocket, the Delta IV heavy, SpaceX says.

    SpaceX has set Jan. 15 to open the launch window, but that window could remain open for days before launch, so booking a flight to Florida for a closeup view is a gamble. In part, that's because the launch also depends on a successful static fire test of the Falcon Heavy on the pad. That test fire is now planned Saturday.

    The SpaceX plan calls for all three Falcon Heavy boosters to return to Earth. The side boosters will return to Cape Canaveral, and the central booster will land on the SpaceX barge.

    Oops.

    The second-stage booster section of the Falcon 9 failed, said a U.S. official and two congressional aides familiar with the launch, who asked not to be named because the matter is private. The satellite was lost, one of the aides said, and the other said both the satellite and second-stage rocket fell into the ocean.

    Howevah...

    The Zuma mission was a success on at least one count: SpaceX successfully landed the rocket’s first stage for reuse in a future launch, a key step in its goal to drive down the cost of access to space.

    Wow. An important billion dollar military satellite of some kind lost, with Space X and Northrop Grumman blaming each other for the failure (N/G was responsible for building not only the satellite, but the "fairing" that surrounded it, the thingy from which the critter would be deployed - the 1st stage worked as advertised and returned as planned. 2nd stage? part of what they're fighting about). That's if it really is a failure. Could this possibly be a "stealth" satellite? One undetectable by the usual suspects on Mother Earth? It's unlikely, but I would be excited if that turned out to be the case. Assuming we ever found out, of course.

    I couldn’t help but think the story was odd in apparent lack of concrete evidence of the failure. They basically say they thought it deployed but they can’t detect it in orbit,,,”No new satellites”,,,so something must have gone awry.

    If you were to deploy a stealth satellite, kinda makes sense that you’d fake a failure, since ppl would be wondering why they can’t “see” it if you say the mission was a success.

    That said: what would be the purpose of a stealth satellite. It’s not like the whole world doesn’t already accept that we have satellites flying over everything.

    It seems odd to me as well, which is why I mentioned it. As for why a "stealth satellite" would be valuable? I can think of some reasons. Our military, China's military, and Russia's military (along with our major allies) all know where those intelligence birds, ours and theirs, are at all times. The orbits are very predictable. Because they are predictable, and because no nation, at least at this time, has the ability to look at the entire planet in extreme detail 24/7, nations that are highly advanced can schedule certain things they wish to keep secret to be timed to happen when their "opponents" birds can't see them. And they do.

    Example? Our nuclear missile subs, those carrying the heavy hitters, and the 4 Ohio class subs that no longer hold atomic weapons, but rather about 152 deadly accurate cruise missiles (that's 600+ cruise missiles we could conceivably launch at an adversary all at once, making it a bad day for someone), go on very long patrols while remaining, ordinarily (unless we badly want to frighten someone), submerged. Say a crewman gets seriously ill and needs to be in a hospital, or fresh supplies are needed for an unplanned extended mission. If we know where the intelligence satellites of our potential adversaries are, a sub can briefly surface by one of our warships, unload the sick guy, and/or take on badly needed supplies, disappear, and those other countries will have no idea that it happened.

    I was thinking more in the lines of a stealth satellite would potentially allow us to "fly" one to "enemy" satellites and attach disarming devices onto them, like maybe a tiny EMP, without anyone knowing, to use later when needed. Then at any time in the future we can bring down all key satellites as prelude to an attack or as part of a defensive response to an attack.

    I don't know the physics of how to deliver an unmanned satellite to get within touching distance of another, much less more than one target, but seems quite advanced and unlikely that a payload small enough to be put on a Falcon 9 would have the instrumentation for maneuvering like that. But it's fun to think about.

    Something like this?

    Interestingly enough, SpaceX launched one of these, the Boeing X-37, for the Air Force (yeah, right) back in September. Check the size of the guy standing by it, and then imagine the doors opening up and little arms placing one of those gizmos you mentioned on a Russian or Chinese intelligence bird. Why not? The problem is not that such a craft couldn't do a thing like that in my opinion, although it wouldn't be easy, but rather that "everyone" could see the X-37 do it. That's where the stealth would come in. Fun to speculate, anyway.

    That is not true. Not all satellite have an orbit. We can track any satellite in the sky that is transmitting RF energy back to earth. However we (not just the US) have the ability to communicate from satellite to satellite, which then allows us to maneuver these 'stealth' satellites. Whatever data these stealth satellites pick up, they transmit the data to an adjacent satellite which then transmits back down to an earth station in order to mask their location.

    The information the general public has access to is well over a decade old. What I can tell you is that if this 'stealth' satellite was anything special, we would have never heard about it, success or failure.

    I knew you space dorks would eat this up.

    Seriously, keep us posted.

    My only question is how many origami Jose Altuve's can you put inside that thing?

    Full-size or tiny origami-size?

    Huh? Please elaborate... The orbit of a a satellite can be adjusted slightly depending on it's fuel capacity, but maneuvering is very limited.

    I thought the whole definition of "satellite" was that it did orbit something.

    Most spy satellites are in geostationary orbit and only use fuel to stay in one position - an interesting point I read in book about keyhole sats in the early 90s... Imagine the Hubble Space telescope with the most cutting edge tech and billion dollar higher costs except this satellite isn't pointed out to space it's pointed at earth like a microscope. (paraphrase) Imagine the 21st century tech being launched now - they can probably tell you if you have dandruff from a 22,000 or so miles out.

    Spy sats in LEO can be boosted to a slightly higher/lower orbit so they arrive over the target at a different than expected time, but this takes years off a sats expected mission as fuel is very limited. There really isn't a 'stealth' satellite - the trajectory of all of the rockets taking them up is known so even the spy sats with vanta black and other low observability goodies can be located by amateurs. Tracking spy satellites is actually a pretty popular hobby.

    This guy Elon is a trollionaire

    Model S
    Model 3
    Model X
    Then there’s SpaceX? You can’t not say “space sex” when saying that name.

    Well, if you are deploying the Putie mind control ray, you'd want that on the down low.

    I poorly stated that satellites are not in orbit. There are those out there not in geosynchronous orbit and I dont mean to imply they are zipping all over the place. We do try to mask the identities and locations of some satellites.

    But yes, most NRO birds are in geosync orbit and while they are spy satellites, they are not a secret.

    The Army recently halted the advancement of the WIN-T program because they are finally realizing its tech is dated and unable to meet its goals. While our current network may work in theaters in the Middle East, it wont cut it against countries like China and Russia. We have been advancing our technology beyond what can be easily found on a google search or information leaked by whistle blowers.

    That said, the general public will not know the cutting edge nature of tech or secretive missions of these spy satellites.
