Yeah it's pretty late for me too... You will always be able to watch it later on the Arianespace website anyway Livestream starting in 10 minutes

Right there !

Cool, thanks ! Actually, i have another problem... I decided to install RT on a non-RSS save, but i can still launch probes without antennas and without connection... i could control a stayputnik probe core with no antenna on the other side of Kerbin, at 300km... The RT connection tab under the MET shows a red calculator, as if there was no connection, and the delay tab shows N/A What did i do wrong ? EDIT : updated the problem here and in the OP

UPDATE : Ariane 5 was succesfully transferred from the BAF (it's like the VAB) to the launchpad ELA-3 on July 13th (the pictures only arrive now) In the BAF, preparing to roll out, view of the crawlerway : Roll-out On the pad : The sky looks very overcast... i hope the weather is still "GO" for tonight

The single SRB configuration works in KSP, too ! you may need a little bit of effort to adjust the thrust and gimbals/tilt of the engines, though EDIT : nice picture :

Okay that's what i was thinking ! thanks for the help ! I'm not sure i want to install RO... i tried it before and was overwhelmed with all the features/content/bugs. I'll just stick with RSS. So maybe i'll use remote tech in another non-RSS game EDIT : i'm not changing the thread to Answered in case someone has another solution

Hi, i just installed remote tech for the first time, and i also have RSS installed. Weirdly the red dot wich (i suppose) is the point supposed to be the KSC where the communications come from is not situated near the launchpad (that is in florida in RSS) but in south america... : as a result my probes on the launchpad have no connections and can not be controlled. Is that a bug or did i go wrong somewhere ? Can you guys help me ? or is Remote tech not compatible with RSS and i have to go back to the original downscaled Kerbin ? Thanks EDIT : Actually, i have another problem...

Welcome to the forums I'm pretty sure you can overcome this problem by just putting your periapsis higher when returning from the Mun... it will ensure you re-enter the atmosphere at a more friendly angle and will let you plenty of time to slow down before you get too low for parachute deployment. Try putting the periapsis at something like 30 km. By the way, that planet is called Kerbin ! Tell us if you make it

Oh hey i guess we live in the same place then what a coincidence let's keep it in english though. I went to the "cité de l'espace" (this space themed park) as a kid and the rocket always felt huge to me. Maybe it wouldn't anymore if i came back there now... EDIT : updated the OP and added a bunch of pictures. Roll of the booster from the BAF (bâtiment d'assemblage final=final assembly building) to the launchpad scheduled today (July 13rd) Funny to see that while the payloads were adapted on the VA224 booster, the core and EAP of the VA225 arrived and were installed in the BIL (it's like the VAB) ! there is a lot going on at Kourou

I meant them ! In France we use commas for decimals... wait there's no one next to it in the pictures...

This is pretty much the whole second stage with an interstage fairing skirt (but i'm not 100% sure on this you may want to check it up). the interstage is big because the second stage engine, the HM-7B, is very long. IIRC the interstage stays attached to the first stage during staging and falls off with it. Yes the ESC (second stage) is very small compared to the EPC (first stage) because Ariane 5 is basically a oversized first stage with a small second stage. Just so that you get the idea : MECO and staging happen when the booster is already flying at around 6900-7000 m.s^-1 and is at about 170km above the surface !! why more struts ? there are 6 of them here for such a small engine !

Hmm with 200k advance funds and 460k completion funds, you probably can make it worth it with ion, but you'll really have to stretch it... I would never pick that contract !

It's probably just an optical illusion... in fact there is nothing for scale on that picture, so it's hard to tell. Ariane 5's EPC (the main core) is actually 5,458m in diameter and 30,525m tall (not counting second stage and fairing). It's very big in reality, much bigger than any KSP rocket !

Yeah obviously, but the main heating factor is the superheated air in contact with the capsule, and anyway when i wrtoe air compression, the teacher saying "no it's not" is wrong...

Pictures : (because we all like pictures) (if anyone is kind enough to teach me how tu use spoilers, i will "spoiler" the huge pictures. Ariane 5's second stage before assembly : And after assembly : (note that the EAP are already assembled !) Transfer to the payload assembly hangar : MSG-4 : (huge pictures !) it's a spinning satellite, by the way, for extra stability Star One C4 : (hey i found a real picture!) UPDATE : Both payloads enclosed in the fairing with the SYLDA (system for double launch) : Star One C4 under the SYLDA bell : And MSG-4 on top : And mating the fairing to the booster : Tell me if you want me to update more pictures of this launch preparation (and actual launch after it will have happened) ! All these pics are from the CNES, obviously

This is flight VA224, Ariane 5's sixth launch this year. Watch it Here ! Launch window is 37 minutes long : -18h42-19h19 Kourou time, July 15th -21h42-23h19 GMT, July 15th -23h42-00h19 Paris time, July 15th-16th Star One C4 is riding the rocket on top, and MSG-4 is under the SYLDAb bell. Star One C4 will be released first, 28 minutes after liftoff. MSG-4 will be released later, at around 40 minutes into the flight. -MSG-4 is a 2ton meteo satellite wich is part of the ESA's EUMETSAT satellite constellation. it is in the white room in this picture. It is normally surrounded by static solar cells (they are covered here.) -Star One C4 is a 5.6ton telephone, television and radio satellite part of the Embratel Star One satellite constellation. Will cover Brasil and relay data in most Latin america and USA. It will be launched on a 70° inclination GEO. (no actual pics found... ?) MSG-4 arriving at Kourou : Arrival of Ariane 5's main core at Kourou : Will update other pics later

for (2) : as i understand it, yes the distance is decreasing at 2*c, but since it is not an object or a physical point it's perfectly possible. It's like a shadow : imagine having a very powerful light source that would light the whole moon from the earth. if you put your hand in front of it it would create a huge shadow on the Moon (assuming the sun is not there). now if you wave your hand very quickly in front of the light source, the shadow on the moon would travel" at several times the speed of your hand... i used the moon as an example but if you take some large object very far away the shadow will be moving on the surface at several times the speed of light... but a shadow is nothing so it's totally OK

Wow ! the cracks on the surface make me think of Eeloo ! Who knows, perhaps SQUAD nailed it and Pluto looks just like Eeloo (except for the color of course)

they would probably break apart.

Physics (thermodynamics) test (highschool) : "the total energy of a capsule re-entering the atmosphere is Q=x J and does not change throughout re-entry. The capsule radiates away -y J during re-entry." And the question was about work, and energy received by the capsule. (i know it's a rather stupid exercise but you know) Then the last "easy" question : what is causing the capsule to heat up ? Me : "air compression in front of the capsule." 2 weeks later---> Teacher gives back copies : i got 0 at that last question. Physics teacher : "no it's friction" Me : intense facepalm. I couldn't convince him.

just wondering, btw : how long does a Mars transfer window last IRL ?

Yeah but lasers seem to be the best choice... Certainly not the only viable option, but probably the only affordable one

Just wondering since this thread was brought up, when is Vulcan's first launch planned to happen ? like 2020 ? or sooner ?

But it's still disproportionally exagerated (1 or 2 "g"s ? no idea)

Pro tip : Just set the mun as target, its orbit is perfectly equatorial. You could try a bi-elliptic transfer to save some deltaV.
