No Upper-stage Explosion after Falcon 9 v1.1 Launch, SpaceX Says

  By Dan Leone | Oct. 1, 2013  
 
   WASHINGTON — Space Exploration Technologies Corp. (SpaceX) issued a statement Oct. 1 denying speculation that the upper stage of its Falcon 9 v1.1. rocket exploded on orbit following the rocket's successful demonstration launch Sept. 29 from the Vandenberg Air Force Base in California.
The speculation was spawned in part by the fact that the U.S. Space Surveillance Network is currently tracking more orbital objects associated with the launch than expected.
In its maiden launch, the Falcon 9 v1.1 carried the Canadian Space Agency's Cassiope space weather satellite and three secondary payloads to low Earth orbit. The launch was a trial for the upgraded rocket — the Falcon 9 v1.1 features a stretched fuel tank, new engines and a 5.2-meter-diameter fairing — that SpaceX now hopes to use to launch commercial communications satellites to geostationary orbit.
The SES-8 satellite owned by SES of Luxembourg, would be the first of these. It is tentatively scheduled to launch in October from the Cape Canaveral Air Force Station in Florida. However, that launch may be delayed as SpaceX investigates why a planned reignition of the second stage following deployment of the payloads could not be completed.
"Regarding the rumors you may have heard about the Falcon 9 second stage, in short, our data confirms there was no rupture of any kind on the second stage," SpaceX spokeswoman Emily Shanklin wrote in an Oct. 1 email. "Following separation of the satellites to their correct orbit, the Falcon 9 second stage underwent a controlled venting of propellants ... and the stage was successfully safed. During this process, it is possible insulation came off the fuel dome on the second stage and is the source of what some observers incorrectly interpreted as a rupture in the second stage."
SpaceX attempted to reignite the upper stage after payload separation in a demonstration of a capability it will need to place satellites into the proper geostationary transfer orbit. However, the reignition sequence was aborted after a problem was detected, SpaceX Chief Executive Elon Musk told reporters in a postlaunch teleconference.
Following the launch, an eyewitness in Reunion Island off the eastern coast of Madagascar posted a photograph on the website Reddit of what amateur astronomers later determined was a cloud of rocket propellent surrounding the spent Falcon 9 1.1 upper stage. By Sept. 30, the U.S Air Force-run Space Surveillance System was tracking 20 objects associated with the launch in low Earth orbit. Experts were expecting to see 11 objects, including Cassiope; the three secondary payloads, one of which released seven independently flying objects; and the upper stage.
SpaceX's explanation of events is copied below:
Following separation of the satellites to their correct orbit, the Falcon 9 second stage underwent a controlled venting of propellants (fuel and pressure were released from the tank) and the stage was successfully safed. During this process, it is possible insulation came off the fuel dome on the second stage and is the source of what some observers incorrectly interpreted as a rupture in the second stage. This material would be in several pieces and be reflective in the Space Track radar. It is also possible the debris came from the student satellite separation mechanisms onboard.
SpaceX will continue to review to help identify the source of the extra debris, but our data confirms there was no rupture of any kind on the second stage.

изоляция обрывалась каждый раз при вентиляции? это возможно?
и при этом не оторвалась при работающем двигателе?

It is also possible the debris came from the student satellite separation mechanisms onboard.

более вероятно, мне кажется... там есть чему отвалиться достаточного размера?

[Ну-и-ну]

Что-то апогей у "отвалившейся изоляции" изрядно различен. Что там - 200 км разницы? Нефигово она "отваливалась", разве что - в процессе разгона, по пути.

Вот про студенческий спутник верю. Что они там наструячили - вопрос.

FAA или кто там, с ними разбираться будут...
Либо лицензии лишат, либо таких исков навыкатывают, что очень долго расплачиваться будут...Хотя одно другому и не мешает.

SES Reviewing Falcon 9 Upper Stage Reignition Abort Ahead of SES-8 Launch
 
 Posted by Amy Svitak 1:38 PM on Oct 02, 2013  
  SpaceX says its Falcon 9 v1.1 upper stage aborted an attempted reignition of the new Merlin vacuum engine during Monday's debut of the upgraded rocket. Second-stage reignition is necessary for Falcon 9 to deliver payloads to geostationary transfer orbit (GTO). 

"The second-stage engine initiated ignition, got up to about 400 psi, encountered a condition it didn't like and initiated an abort," SpaceX spokeswoman Emily Shanklin said Oct. 2. "We need more time to review the data before we come to any sort of definitive conclusion, but we are confident we will be able to address it before the next flight," she said, adding that the abort "wasn't anything fundamental" and that a planned late-October launch of the SES-8 satellite for Luxembourg fleet operator SES "is still on track to launch in about a month."

SES says it is now discussing the reignition abort with SpaceX ahead of the launch, which could also be delayed by the U.S. government shutdown as it affects operations at Cape Canaveral AFS, where the Orbital Sciences Corp.-built SES-8 spacecraft is to be launched.

Falcon 9 Explosion – Upd ate
             
          Posted on 2013 October 7      
                     AS of October 7, SpaceTrack had provided element sets for twenty objects. All of which had their first data issued shortly after the September 29 launch. Ten of them only appeared once or twice during the first 24 hours and are no longer being upd ated, the remainder have received updated se ts during the week that has followed since.
Of the updated items, two are exhibiting rapid orbital decay and will probably have re-entered by the time this article appears. Another three are decaying nearly as quickly but will probably last about another week before re-entry (the missing ten may have decayed too quickly for Space Command to find them a second time). The other five are maintaining their orbits but the spread of data on three of them indicates that tracking sensors do not have a particularly good 'lock' on them.
At the start, they showed a scatter in apogee between 1350 and 1654 km and in perigee between 235 and 415 km. Inclinations varied between 80°.94 and 81°.04. Obviously, with the rapid orbital decay rates of some, the spread is now significantly greater.
Falcon 9
SpaceTrack has catalogued 2013-055G/39271 as the Falcon 9 rocket body and latest data show it in an orbit of 319 x 1489 km, 81°.0 inclination, very close to the 325 x 1500 km, 81° target orbit issued by SpaceX prior to launch.
The Payloads
The Catalogue does not yet contain separate identities for the payloads and, most unusually, they are not represented individually by any of the highly-scattered objects listed so far! There are more Objects to come.
SpaceTrack has issued Radar Cross Section measurements for all the fragments. Most values indicate that the objects are quite small with current values generally less than 1. They will change with time as the tracking systems get more readings.
There is a single, very obvious exception (2013-055B/39266) currently shown in an orbit having parameters within 1 km of the rocket body. Its RCS value is a massive 42.
At the moment, it seems to be a single entity that represents the payloads and their support equipment as one object. They are so close together that Space Command is not yet prepared to pass individual orbital datasets to SpaceTrack for publication. One thought process says that maybe they are too close together for them to be distinguished by tracking sensors. An alternative reason might be that the US military does not want to reveal precisely how good its sensors are. Either way we have to wait for Spacetrack to publish element se ts before we see actual orbits for the individual satellites.
Or do we.......
In the Seesat-L discussion forum, amateur satellite observer Greg Roberts of South Africa is providing a steady stream of observations that show the six individual payloads and just how close together they are.
The Fragments
The scattered nature of the objects catalogued so far indicates that they have arrived in their individual orbits as the result of an explosive event. Whether by it was a conventional explosion or caused by rupture of a pressurised object can probably only be answered by SpaceX, the rocket manufacturer, because the Falcon 9 is highly likely to be the culprit. Of the debris, most of it is in orbits with a lower inclination than the Falcon 9 upper stage indicating that it was blasted sideways. The up and down distribution would have been caused by the debris spreading in a fan of sideways directions as it was ejected.
The Falcon 9 was to have executed a sideways manoeuvre after it released the payloads but the rocket firing was aborted. SpaceX says simply that the rocket motor ceased its ignition routine when the chamber pressure reached 400 pounds per square inch (apologies for the units). Combined with the evidence of an the orbital debris, it leads to the question of whether there was an explosive loss of pressure. SpaceX's next customer is slightly worried by events.
SpaceX
After the original zary.info Blog entry was published, the SpacePolicyOnline.com website asked a question of SpaceX concerning the possible explosion. The response was "....Following separation of the satellites to their correct orbit, the Falcon 9 second stage underwent a controlled venting of propellants (fuel and pressure were released from the tank) and the stage was successfully safed. During this process, it is possible insulation came off the fuel dome on the second stage and is the source of what some observers incorrectly interpreted as a rupture in the second stage. This material would be in several pieces and be reflective in the Space Track radar. It is also possible the debris came from the student satellite separation mechanisms onboard....."
If this were true then the "insulation material" would initially in a similar orbit to the rocket but the orbits would decay rapidly because of the low density of the material. The statement makes no reference to the failed rocket ignition as a possible factor and given the closely bunched nature of the payload orbits, their separation mechanisms are probably still to be catalogued and are not likely to be among the debris.
Some of the material is in rapidly decaying orbits but the starting point was a spread of orbit heights averaging 100km either side of the rocket, indicating that they were blasted away at up to 50 metres per second – not exactly a gentle separation. Four items are in relatively stable orbits indicating something more dense, maybe pieces of dense plastic, metal or ceramic.
Futures
SpaceX may release more information as time goes on but it will probably be in response to pressure from potential customers. Zarya.info has on several occasions posed direct questions via e-mail to SpaceX about discrepancies in earlier missions' detail it has never once responded. As a result, those discrepancies remain on file and suspicions grow of cover-ups.
The company has a loyal and appreciative fan base among the public and it is not treating them as intelligent people by feeding them only the good news, hoping they wont spot the problems!

Дык там два спутника в состыкованном состоянии, потом они должны расстыковаться и начать хоровод - как у FASTRAC в свое время было.
