Did the ExoMars Mission Narrowly Escape a Launch Disaster?

- dbpokorny 11y agoThe extent to which the space programs of nation states are little more than fig leafs over what are in reality a bunch of maladjusted homicidal maniacs, and the extent to which the average person has absolutely no concept of this can be really frustrating at times. The whole notion that it is "noble" to "reach for the stars" when in reality everybody can see you're trying to develop ICMBS so you can extract resources from competing nation states over threat of nuclear annihilation...makes me want to kick their children's genitals until they become bloody pulp.
- dang 11y agoWe've banned this account for repeatedly breaking the HN guidelines. It's a pity, because some of your other comments are good. That's why we warned you before and even sent an email asking you not to do this. But no one gets to comment like this on HN.
- dang 11y agoPlease don't do this here.

- ohitsdom 11y agoSome better info here on the incident and more details on the venting issue with the Briz-M stage: http://www.popularmechanics.com/space/rockets/a20044/exomars-narrow-escape-launch-disaster/ http://www.popularmechanics.com/space/rockets/a20044/exomars...
- dang 11y agoOk, we changed the URL to that. Thanks! It isn't obvious which is better, but since the other URL (http://russianspaceweb.com/exomars2016-eop.html http://russianspaceweb.com/exomars2016-eop.html) triggered a useless discussion, perhaps we'll have better luck with this one. Hint: everything in the current thread is marked off-topic, so if anyone would care to seed a new discussion with something substantive, that'd be grand.
- kartikkumar 11y agoI wonder if there's enough data to reconstruct the demise of the upper stage. Re-entry physics is extremely interesting and complex. ESA has a number of articles on the analysis of the re-entry of the GOCE satellite [1]. There are a couple of tools that are considered the defacto standards for computing high-altitude re-entry physics like SCARAB and ORSAT [2]. A colleague of mine working in the same EU project as me [3] is developing an open-source tool that can switch between low- and high-fidelity computations [4]. Wonder if any of the observations recorded are valuable to calibrate these models.

- LoSboccacc 11y agoIsn't that stage on a escape trajectory?
- kartikkumar 11y agoThe upper stage gets left behind in Earth orbit. The Briz-M stage provides the kick to propel the payload to a higher orbit and then usually there's a kick motor that follows up, in this case, delivering a Trans-Mars Injection maneuver to set the spacecraft on its way to Mars. EDIT: Actually realised I'm wrong since the Briz-M is the 4th stage, not the 3rd. The 3rd stage remains in orbit and then splashes down and the 4th stage actually provides the entire kick for TMI [1] [1] http://blogs.esa.int/rocketscience/2016/03/13/why-exomars-ride-to-space-takes-the-time-it-does/ http://blogs.esa.int/rocketscience/2016/03/13/why-exomars-ri...
- LoSboccacc 11y agoSaw some diagram and it seems after the kick it has an additional burn to get it into a graveyard orbit instead of goong to mars along the payload. Maybe that burn which failed
- giomasce 11y agoIt always impress me how much it is difficult to track things in space, so that still in 2016 we may not have an idea of what is happening up there...
