insert_name 1,416 Posted December 10, 2017 (edited) There doesn't appear to be a thread for European rocket launches so I made this. This Tuesday ESA is launching Galileo 19-22 https://spaceflightnow.com/2017/12/08/galileo-navigation-satellites-buttoned-up-for-launch-on-ariane-5-rocket/ Edited April 26, 2018 by insert_name Quote Share this post Link to post Share on other sites

Canopus 937 Posted December 12, 2017 I just love the stubby look of the Ariane with the Hypergolic upperstage. Quote Share this post Link to post Share on other sites

Canopus 937 Posted January 25, 2018 So when they are talking about "all electric satellites" they only mean propulsion. Attitude control is still bipropellant? Quote Share this post Link to post Share on other sites

sh1pman 3,328 Posted January 25, 2018 Just now, Canopus said: So when they are talking about "all electric satellites" they only mean propulsion. Attitude control is still bipropellant? I think so. Why else would they fill an “all-electric” satellite with hypergolics? Quote Share this post Link to post Share on other sites
Canopus 937 Posted January 25, 2018 (edited) 30 minutes ago, sh1pman said: I think so. Why else would they fill an “all-electric” satellite with hypergolics? Thats why i'm asking. Strange to insist on calling them all electric then. Edit: the Answer seems to be that other satellites, like Al Yah 3 on this launch, use both Hypergolic and Hall Effect thrusters for Propulsion where as SES-14 uses a Hall effect thruster for circularization and stationkeeping.

GoSlash27 4,258 Posted January 25, 2018 Possible failure? There was no telemetry after S1 Sep and still waiting for confirmation of Yahsat sep. Ouch. Looks like they lost contact moments after S2 ignition and now they're looking for the sats, trying to figure out if they made it or reentered. Potentially the first Ariane failure since 2004, I believe. Quote Share this post Link to post Share on other sites

tater 20,012 Posted January 25, 2018 This is really unfortunate. Wonder if it impacts the JWST. Quote Share this post Link to post Share on other sites
Canopus 937 Posted January 25, 2018 Definitely a bad way to end a day. Say they only lost communication with the stage, would it continue its mission on it's own and still release the payloads? Quote Share this post Link to post Share on other sites
