Weather paying respect to Apollo 11 (-1, Troll)

damn_registrars (1103043) | about 2 years ago | (#41125025)

With Armstrong's passing today, the weather is holding up NASA to get them to reflect on their priorities.

Not sure what you're saying, and obviously I don't know the guy, but I'd imagine he wouldn't want NASA to stop their work on his account.

Really, we should fire off a 21 rocket salute to the man.

And this is another reason to start a lunar base/launch facility. Very few weather problems, other than solar flares.

Weather may also be affecting the birds.

The question is, which kind of weather affects them more?

"Susceptibility to Weather": Today's Disconnetion (2, Interesting)

reallocate (142797) | about 2 years ago | (#41125157)

"Susceptibility to weather delays" is a problem for many things, like high school baseball games, outdoor weddings, parades, the morning run, fastidious hair styles. That's especially true when, you know, a hurricane is in the neighborhood.

Here's the thing: Real space travel needs to begin and end in space. Low Earth orbit is the equivalent of tooling around the harbor.

Re:"Susceptibility to Weather": Today's Disconneti (0)

Anonymous Coward | about 2 years ago | (#41125249)

Yes. The ISS is great, but we need a "moveable" ISS next -- a constantly running "ferry" if you will -- that never lands back on a planet but just steadfastly carries people/cargo between low earth orbit and low mars orbit.

Re:"Susceptibility to Weather": Today's Disconneti (1)

Dan East (318230) | about 2 years ago | (#41125851)

I thought that comment was a bit off as well. There are usually multiple launch windows to reach whatever orbit / planetary alignment the payload requires, and on rare occasions things do come down to the wire, but usually there is ample cushion to work around the weather. The only other issue is if a launch area had so many launches lined up that they would get backed up, but I really don't think that's a problem. Actually there are lots of facilities vying for launches, especially since NASA is using more commercial providers and disseminating what was pretty much a monopoly at Cape Canaveral.

Regardless, even if the launch system could fly through a hurricane, it is best to have good weather for multiple visual and radar observations of the launch in case anything goes wrong.

"Low Earth orbit is the equivalent of tooling around the harbor." Funny thing. None of the people who say that have even made it out into the harbor.

First delay not water (0)

Anonymous Coward | about 2 years ago | (#41125295)

RTFA, the first delay was due to people violating the launch safety zone in boats. I don't mind weather interfering occasionally, but people ignoring warnings is a big problem.

I think they should have launched even with the clear zone violations. Serves them right if a rocket landed on them. Think of it as evolution in action.

Terrier-Improved Malemute (-1)

I'm trying to imagine how mating dogs this way produces sounding rockets, but I got no clue. On the other hand, if I mate my dachshund with my neighbor's German shepherd, perhaps I'll get an iPad out of it

Launch requirements factoid (4, Informative)

dtmos (447842) | about 2 years ago | (#41125373)

There are lots of reasons for weather delays of rocket launches, but one of them is wind. I've been told (by actual rocket scientists, with only a few Green Martians* in them at the time) that there are two critical factors related to wind -- the wind speed itself and its variability, i.e., gusts -- and that the reasons both trace back to the limitations of the directional-control system of the engines (i.e., the gimbals) and the guidance system of the rocket.

The limitation on maximum wind speed is related to the range of control of the engines (i.e., how many degrees off the axis of the rocket the engines can point), since that eventually works back to how large a wind-compensating vector is available to the guidance system. The gust limitation is related to the response speed (slew rate) of the engine gimbals, since that eventually works back to how fast the guidance system can respond to changes in wind speed and/or direction.

Can someone parse this sentence?

cratermoon (765155) | about 2 years ago | (#41127443)

Silly answer: It's a Terrier Malemute with an improve Malemute upper stage.

Serious answer: it's a sounding rocket [astronautix.com] based on the US Navy RIM-2 Terrier surface-to-air missile from the 1950s as the first stage, with a Thiokol Malemute upper stage. The Terrier is used as a first stage for a variety of small rockets.

A recent launch of note that used Terrier-Malemute variants was ATREX [nasa.gov] .

Rumour is this is because they were using Linux (0)

Anonymous Coward | about 2 years ago | (#41127673)

Most computer experts now agree that Linux is, without exception, less secure and less reliable than commercial alternatives such as Mac OS X Server. However, many IT departments insist on using the "free" software, which they rationalize to management by pointing out the initial cost difference, because they have a perverse incentive to do so. A reliable operating system would mean less maintenance work and therefore cuts to IT budgets.

It's well known that Mac OS doesn't get viruses, but many Fortune 500 companies are still using the hackers' choice for operating systems (based on its open, easy to penetrate nature) because of this IT department scam.

How many more space ships have to be lost?

Re:Rumour is this is because they were using Linux (0)

Anonymous Coward | about 2 years ago | (#41128677)

Look, I know you're a troll, but someone will believe you. MacOSX (server or desktop) has terrible security. At least OSX server has a good GUI for its firewall (unlike desktop), but Apple has a track record of denying security vulnerabilities, then waiting until there's an uproar before fixing them. Even Microsoft has a maximum 1-2month wait;Apple has gone 6months+.

I really don't know what bad weather has to do with rocket launches.
These things fly very fast, basically straight up and would do so through clouds and bad weather.
So what's the issue(s)?

overconservative (1)

r00t (33219) | about 2 years ago | (#41133427)

Is there an actual problem with the weather, or are we just being wimpy? When is the last time weather destroyed a rocket in flight? We're being too careful if this isn't a decent portion (perhaps 10%) of the failures.

You're going to lose a few rockets anyway. If you don't even up the causes of failure, you're being pointlessly reckless in some areas while being pointlessly fearful in others.

Darth Snowshoe (1434515) | about 2 years ago | (#41136117)

The cost of waiting a week to launch RBSP after a hurricaine has passed is waaaaaaay less than the cost of letting RBSP crash because of weather. RBSP's development costs - I don't know for sure, but on the order of 7 or 8 hundred million dollars(?) It's not the same as "hey, let's go for it on fourth-and-long". This isn't football. Nobody's going to think its a "ballsy" decision to launch a rocket in an oncoming hurricaine (unless that what it was designed to do.) What they'll think it is, is "stupid".

Re:overconservative (1)

r00t (33219) | about 2 years ago | (#41140249)

Development costs don't get wasted unless you never succeed. Construction costs get wasted for every device that gets built but crashes or is never launched.

These delays are not free. You have the cost of an aborted launch, and you have the cost of not performing the mission for a period of time. You also create delays for other launches from the same location, causing costs that are externalized to some other program.

Re:overconservative (1)

RocketAcademy (2708739) | about 2 years ago | (#41162453)

The launch rate from Wallops Island is not so high as to be a concern. NASA only conducted 13 sounding-rocket launches in 2011, not all from Wallops.
