SpaceX armchair quarterbacking
In article , frédéric haessig says...
"Geoffrey" a écrit dans le message de news: .com... No, it's not. Most of the early boosters did suborbital tests first. Saturn 1 did about four suborbitals before they tried an orbital, for example. Did any rocket devellopped since the 70s do so? Especially any commercial one? Ariane didn't, even for Ariane I ( which was sucessfull - the failures were on the 2nd and 5th flight ). Neither Sealaunch, nor Delta III or Delta IV, nor Atlas V did, AFAIK. Similarly, the new version of Russian rockets don't, and I don't think GSLV and PSLV did. I'm less sure about the japanese and chinese rockets. Delta III/IV and Atlas V are expressions of corporate ego on even-numbered days, attempts to feign continuity with earlier vehicles on odd days, and neither of those allows one to admit a suborbital test or three might be called for. Sealaunch uses the Zenit booster, whose first two flights were suborbital by design. All of the other new Russian rockets are ex-ICBMs, with lots of suborbital flights under their belt, except the Angara which hasn't flown at all. The PSLV's first flight was suborbital, though not by design. The Japanese H-II was orbital from the start. Same for the M-V as such, but earlier M-series rockets had a suborbital heritage. Likewise the J-1. The only operational Chinese launchers have been derived from the DF-5 ICBM, again plenty of suborbital flights there. The new Kaituozhe has flown twice and not reached orbit either time; the Chinese aren't saying much about what it was intended to do. People who aren't investing massive ammounts of ego into government megaprojects, and even some who are, seem to prefer shooting a bit lower than Earth orbit for their first test flight. We'll see how SpaceX does with their approach, but it's not the way I would go. -- *John Schilling * "Anything worth doing, * *Member:AIAA,NRA,ACLU,SAS,LP * is worth doing for money" * *Chief Scientist & General Partner * -13th Rule of Acquisition * *White Elephant Research, LLC * "There is no substitute * * for success" * *661-951-9107 or 661-275-6795 * -58th Rule of Acquisition * -- NewsGuy.Com 30Gb $9.95 Carry Forward and On Demand Bandwidth |

The flaw in this plan is that this Falcon I team have been busy on other projects. This mostly explains this five month delay until the next launch when this team has to be reassembled and work started. That has to be among the stupidest ways to run a project I've ever heard. Seems to be more or less par for the course when a system goes from development to being operational If the Falcon I was operational, you'd have a point. D. -- Touch-twice life. Eat. Drink.

SpaceX armchair quarterbacking
Blast your loved ones remains into space is already getting quite
popular it seems. Indeed they will put anything you want into space if you can pay the fee. It does seem like this market has proved viable (at least the ashes of loved ones part). Whether it will be large (either in terms of kilograms, or number of customers) is a different question. As with a lot of things in the space industry, this depends not only on whether the demand is out there, but whether anyone is trying to develop that market. How many people have bought this service to date? Some steady but relatively small number. How many people would, if it were pick your favorite choice from flying more often, marketing more widely, cheaper per gram, etc, etc? That's harder to say. |
