A Journey to Gauss

16 posts in this topic

Posted (edited)

This will be a report of how I am doing a manned mission to the Gauss system. The planet Gauss is one of the outer planets from the "Galileo Planet
Pack".

First of all I would like to introduce you to the planets and moons.

BYmq9QC.jpg

I will not be able to do much with Gauss. I will put two Relays in a polar orbit and maybe let my Lander explore the atmosphere a little bit.
On Loki I want to explore all biomes with my Lander. If necessary, the mothership will be refueled from here.
Catullus is a beast. The gravity is not very strong, but the atmosphere is 5 atm and reaches an incredible distance into space. For this reason I have
built a rocket and not an Spaceplane. Perhaps a plane could go, but I try it on another day.
Although Tarsiss has a rather thick atmosphere, the gravity is very low. Here an SSTO will be used and also all biomes shall be explored.

 

These vehicles are used:


The mothership brings the Lander and the crew.

DnaJYkW.jpg

 

The Survey probe has to explore the minerals of all bodies.

d1YE1Js.jpg

 

The Lander for Loki. Will also serve to refuel the mothership.

npYFDOq.jpg

 

The SSTO for Tarsiss. Will stay in Orbit of Tarsiss after used.

7MoioKo.jpg

 

Here ist the Ascending vehicle for Catullus. Looks a bit like an Eve Lander.:D

All vehicles have been completely built with the "stock" parts. I will like the last time (A Journey to Tellumo) describe the vehicles more precisely when
they are used.

Here is a list of the mods used

First I bring the mother ship into orbit. At this point I would like to explain a few things about the mother ship:

The maximum crew capacity is 8 Kerbals. At the top is a Sr. Docking Port to dock the Lander or my tanker. The lower tank can, if required, be coupled to
the Lander so that the Lander can bring more fuel to the mother ship.
In the Cargobay is space for a Rover that can be mounted down at the Lander, a Parachute which can be docked at the Top of the Lander and a tug to bring  
the rover and/or the Parachute to the lander, if necessary.
Furthermore, two shielded docking ports are installed on the right and left to take probes or relays. On the back of the Cargobay is another, so that a
crewshuttle or similar vehicle can dock. If nothing goes I use the claw of the Tug if I have no other possibility.
I use RTGs for power generation because Gauss is far from the sun.

The total weight of the rocket was at launch 3.828,22t and cost 1.920.653 Funds, The biggest rocket I've ever had. The rocket is reusable and will land
as close as possible to the KSC.
The mothership weighs 401.58t when it reaches the orbit and then has about 5000 m/s dV. After that, it must still be full tanked and will weigh over 870t
with Relays and Landers etc. With full loading it has a range of 7900 m/s dV. Without Lander, Relays, Chutes, Rover and Tug it comes to 10228 m/s dV.

mZgTsj4.jpg

 

Here is a picture of my first attempt to start the monster.

Tdz7Kqf.jpg

 

Unfortunately the connection rocket/mothership was not very strong and I had to experience this here.

rC09MuQ.jpg

 

After I had then installed Struts in the appropriate place, it worked perfectly. The TWR is at the start 1:1.36 and I have a dV of 3960m/s. That should
be more than enough.

X0VRxiM.jpg

InmFPGb.jpg

 

In the orbit I still have 825 m/s dV, so I used less than 3200. I always start by hand and do not use mods for it, i think the result is not bad.

T7QwnBa.jpg

 

After that I decoupled the rocket and aimed towards KSC. I use 2 foldable heat shields for re-entry.

fDRZwO9.jpg

 

Here is a picture just before the touchdown. I came quite close to the KSC. Shortly thereafter, I then separate the shields, since I must brake the last
meters with the engines.

sOybXdP.jpg

 

made it

Bwu54T9.jpg

I received 765,000 funds back. That was worth the effort.

As you may have noticed, some of the things on the mother ship are still missing. 2 relays, the lander and the crew still have to be brought up. I will have to make some starts until I have everything to go.

I'll be keeping track of this thread. Good luck with Catullus in particular, that one looks like Eve but worse.

As long as there's a break in the action, nice use of colored lighting. I really like the aesthetic!

@eloquentJane

I found Eve worse. This is certainly because I was still inexperienced. I needed a very long time until I had something useful. At Catullus I already had a basic vehicle - the Eve Lander. But I still do not want to tell too much now.

 

@Cunjo Carl

Thank you for the compliment. I've been inspired by eddiew. I also wanted to have a nice spaceship. Before, I've only ever put something together.

 

 

 

So...what do we still need?

The Lander.
He has space for 3 Kerbals, is able to refuel himself and the mothership and has all scientific equipment (except for the Survey scanner). At the top one
can put the parachutes from the Cargobay of the mothership. Below is the Sr. docking port for docking the mothership or to attach the rover. I also added some ladders to explore the surface and pack the parachutes again.
Without equipment he has a dV of 3.545m/s, a TWR of 2.25 and weighs 97,755t. With Rover and Chute he has 3.313 m/s dV, a TWR of 2.17 and weighs 101,630t.

(How is this actually in the forum with the separators? In Germany we use the "." To separate the thousands and the "," by fractions of a number. Is this
done differently in the forum? Then I would adjust.)

CLtpTkq.jpg

 

Here is a picture just before the start. I've used a reusable rocket again. It is able to bring approximately 110t into the orbit. Unfortunately, I
forgot to document the re-entry.

yYVlUXE.jpg

 

Disconnect the rocket after reaching the orbit. Then I planned a rendezvous with the motherhip...

Jxr0sQX.jpg

 

....and docked the lander to the bottom of it, because the mothership needs the free Sr. docking port for the tanker. The mothership is in a high orbit of 5,000km, otherwise the tanker will always burn a lot of fuel to reach a low orbit. Unfortunately, I can make no use of Obertheffects. There are still 2 probes and a lot of fuel to be delivered.

8R7hFUu.jpg

 

Now comes the Survey probe.
It is equipped with ion engines, since it will probably need a lot dV to explore all bodies. If there is still enough fuel left, it can travel to the
next system. It owns 12 RTGs, as solar cells are no longer particularly effective so far away from Ciro. The dV is 12.151 m/s and two ejectable tanks.
How much I can use at once until the batteries are empty I still have to test.

5rSFcFn.jpg

 

A picture of the start. This time without reusable rocket.

RngGyRx.jpg

 

After reaching an orbit of 100km, the orange tank remains. Together with the Poodle I have then almost 2693 m/s dV available before I need the ion
engines. Here I have already planned the maneuver to Gauss - 2358 m/s. This is enough to make corrections. I have to do so, because I certainly can not burn so much dV in one piece with the ion engines. 

And split the maneuver - Oh no!:P

p6n6wsY.jpg

 

In the next part I will launch the Tarsiss SSTO.

Now comes the Tarsiss SSTO.

It has room for 3 kerbals and has all the scientific instruments on board. The ISRU equipment is located in the Cargobay. For drilling, the rear landing
gear must be retracted. The main engine consists of 2 LVN. However, these have a terrible ISP on the surface of Tarsiss. That's why I have 2 Spark
engines to get higher before I use the LVN.
The range is about 5900 m/s dV. To get it into the Gaelorbit I will still use Rapier engines, which are then discarded. Fully fueled it weighs 44,535t,
empty 19,735t. The wings have an angle of incidence of 2 degrees.

IRXlXam.jpg

 

And here we are already on the runway. Unfortunately, I had no experienced pilot and so had to take a newbie. This is his very first flight and he can
fly to Gauss immediately.

XNjBCYV.jpg

 

Here is a picture shortly before the rapiers switch into the closed circle. The settings of the fuselage I have chosen so that the fuselage attached to the
rapier are emptied first. So I can throw them off soon and have more range.

nJtTyZy.jpg


And here it is. No more oxidizer and the tanks are empty. The rest have to do the LVN.

0fylExO.jpg


I chosed an orbit of 300km. We still have 5276 m/s dV and need 2371 m/s for the initial maneuver to Gauss. I think this is enough to get to Tarsiss. 
For over six years, the poor fellow must now sit alone in his cabin.

It's not really a single stage to orbit if it jettisons those rapier engines. It looks like a pretty good spaceplane though.

The only thing missing is the Catulluslander.
When reading the description of Catullus, I had the feeling that a kind of Eve Lander would be necessary. The first test looked very good but I had much
too much thrust and so I exchanged 2 vectors for 2 darts. Due to the weight reduction I was able to make room for 2 more kerbals and bring a little more
fuel. The performance was incredibly good. Due to the loss of Gimbal because of the missing Vector, I had to install a Reaction wheel. This could be a
bit difficult when starting.

Here is a more detailed description:

The core consists of a dart engine with an upper stage consisting of a terrier engine. Around the core are 6 more dart engines arranged in an Asparagus
design.
These are attached to the core with small hardpoints, since the TT-38 radial decoupler was too close to the core and something often exploded. The TT-70
radial decouplers were too draggy. That's why I had to use Fuel Ducts. To be sure, I then attached Sepratrons, which together with the Decouplers
trigger.
All ladders, parachutes, landing legs and scientific instruments are attached to decouplers and are separated shortly before or after take-off. The
parachutes I have turned something, so that they do not destroy the landing legs when falling down.

The whole thing weighs 62,485t. Stage 1 has a surface TWR of 1.55, Stage 2 TWR is 1.51(Surface), Stage 3 TWR 1.41(Surface) an the last Stage has 0.99
(Vacuum)). Total dV is 7522 m/s (Vacuum). The Lander has room for 3 Kerbals and they should be able to walk on the surface an collect the science from the equipment, if the ladders are
mounted correct.

xN21omR.jpg

 

Below, I have built a transfer stage with 8 LVN, which has 5024 m / s dV. And underneath that my tried and tested 200t SSTO Rocket.

Ct2v9Qk.jpg

 

So it looks all together when it is on the launchpad.

uaoUXUS.jpg

 

After reaching the AP of over 70km I open the fairing.

dvHPX2i.jpg

 

Since the payload weighs only 130 tons and my SSTO rocket can do 200 tons, I have brought the Lander to a 200 km orbit before I separated it.

EZeeEJU.jpg

 

After that, the rocket returned to the surface.

xnLsDwf.jpg

 

Here is a picture just before the surface.

5spplKQ.jpg

 

Just 3.2 km before the launchpad, that's fine.

hzvpvut.jpg

 

293,000 Funds Cashback

43NHbUW.jpg

 

Then I increased the orbit of the Lander to 500km and planned the initial maneuver. The transfer stage has 4,718 m/s dV and after the burn there remains
around 2,400 m/s.

VNxnEFx.jpg

But now we have everything, right?
Noooooo.....
The mothership still needs 2 probes and must be refueled. Does not that end at all?

Ohmmmmm ...
Yes. I mean, actually, that it's getting away from Tarsiss in one piece. But I'll call it Spaceplane in the future.

Ah I see. So it is an SSTO just not at the homeworld. In that case I think the terminology is accurate (similar to how a Laythe SSTO in the stock system wouldn't necessarily be an SSTO at Kerbin but would still be an SSTO where it's supposed to be one).

Since the mothership still needs two Relays and crew, I have thought of bringing the stuff with a SSTO into the orbit. To this I have developed a brand
new one. It should have enough space to load a rover and 2 Relays to refresh the equipment of a returned mothership. Also place to exchange the team. In
the picture are now only 2 Relays, since a rover is already in the mothership.

xZUOaHR.jpg

 

It actually worked quite well (Apart from the fact that the runway was not enough. 3 times it still bounced in the grass until finally it was in the air)
and already on the first flight I reached the orbit. Unfortunately, I did not have enough fuel to reach the high orbit of the mother ship. This is not
going as planned. So the mothership had to go to the SSTO, since I have to refuel anyway that does not matter. But the Lander I left in the parking
orbit. Otherwise, I may have to refuel 3 times.

IHF78cp.jpg

 

The Relays I have equipped with RCS so that they can come alone to the docking ports without having to use the Tug. In the picture you can see that the
first Relay is already hanging on the mothership and the second is straight on the way. After docking to the mothership, I detach the RCS from the
Relays, which we no longer need.

mqzKw6Z.jpg

 

Now the mothership can return to the Lander. Then the tanker arrives and gets the mothership just two-thirds full. I need to bring over 100,000 units of
liquid fuel, but the tanker has only about 60,000 units. That thing is quite thirsty.

SkwWNRA.jpg


And so the tanker goes back to Iota.

qtUT717.jpg


While the tanker produces fuel, I want to land my brand new SSTO. Oh boy, I should have tested it before - of course, it is not at all stable at the re-
entry and I can not slow down early enough. I have flown too far and have to turn around to get to the runway. At least the landing approach now looks good.

hvcXzDj.jpg

 

Thank god I have pressed F5 before, the tail has touched the runway. 6 times the same until I had it down.

aYhWYNn.jpg

 

Here you can see why. The main gear is too far forward. This SSTO I need to revise and without test I run no longer the thing.

d4gh8HE.jpg

Once I have to refuel and then I can go.

Where were we? Oh yes, we still need fuel, a lot of fuel.

The tanker filled his stomach on Iota and is about to burst. That should be enough to get the mother ship full.

UdfCZKi.jpg

 

I have to be careful not to forget one of the many tanks.

XxuvCr0.jpg

 

After the undocking, I check again that all tanks are full?
Check.
All Relays docked?
Check.
Rover on board?
Check.
Tug too?
Check.
The lander at the front of the mother ship?
Check.
Shut off the lander's engines?
Check.

r8EZIvw.jpg

 

Then it can finally go. I plan the course to Gauss and carry out the maneuver. 21 minutes burning time - Urgh .....:confused: During the burning process the two
upper LVN engines fall out - argh.:/ Through the hardpoint there is no supply and I have to refill by hand. Hopefully I will not miss Gauss.

opyqN4P.jpg

 

Next is the Survey probe. Because of the Poodle engine, burning is faster. No failures or other dung. I meet Gauss very well.

N65dB5w.jpg

 

Then comes the Catullus Lander. This time it is almost 14 minutes of burning time - well, it will be finished sometime.;.;

w6Z7ZLJ.jpg

 

The Tarsiss SSTO also takes almost 11 minutes - I do not like anymore.:huh:

2THPCAh.jpg

 


Somewhere in the middle between Gael and Gauss, I then make corrections. Basically, I change the inclination only when I have left the sphere of
influence of Gael. This costs considerably less fuel. The individual maneuvers follow in detail.

The Survey probe still has 300 m/s dV in the transfer stage. 
I need 6 m/s to adjust the inclination roughly. This does not have to be so exact, because I have to go anyway at Gauss still 90 degrees. Important is
only a low periapsi to break cheap - here I have 600 km. The remaining 294 m/s I will use to slow down when I am at the Periapsis. That fits quite well -
I should reach a nice high apoapsis. The inclination changes then becomes nice cheap. Only then will I need the ion engines.

LXUJO5U.jpg

 

With the Catullus Lander it becomes more difficult. 
If possible, I want to enter the sphere of influence of Gauss so, that the trajectory is so diverted that I then arrive at Catullus. With as little
inclination as possible. After getting back and forth I managed to reach this with 15.1 m/s a periapsis of 288km at Catullus and almost 0 degrees of
inclination. The atmosphere starts at 280km - I am very satisfied with it. When the Lander arrives at Catullus there are still over 2150 m/s dV available
to slow down, which should be enough.

Ryf2etc.jpg

 

The maneuver for the mothership is getting slightly easier again. 
I set Loki as the target to see the mark for the AN/DN Node. Then the periapsis is placed as far as possible on this mark. Now, if the braking maneuver
has been performed, one of the AN/DN marks is near the apoapsis. There the inclination can then be adjusted cheaply. Then I see further where I should go
first.

HPpbw4u.jpg

 

The Tarsis SSTO will be the last one, and it will be difficult again. 
Just like the Catullus Lander, I would like to slow down at the periapsis of Gauss and then reach Catullus with a small inclination and low periapsis.
The first maneuver costs 7.8 m/s dV. At the periapsis of Gauus I have to brake then 327,48 m/s, so that I reach a periapsis of 280km at Catullus. Next I
have not planned yet, which becomes too inaccurate. Anyway, then at Catullus is planned a breaking to reach an orbit at Tarsiss.

I7JPO0d.jpg

Now I'm finally up to date, In six years it continues.:D 

It is possible that the reports are now slower and/or shorter because I do not know how quickly I will progress.

So fast 6 years go by and the mothership with the fat-headed little green people has arrived at Gauss.

First, I get the science for the High Orbit of Gauss.

oVX5E99.jpg

 

Then I brake the mothership around 300 m/s to reach a high AP. The PE lies easily in the atmosphere of Gauss, so I get at least some data from the
planet. Don`t forget the low Orbit science.

8QnksnG.jpg

 

Actually, I wanted to first explore Loki, but while watching the orbit I noticed that I am very close to Catullus. And so I decided to go straight to
Catullus - Loki has to wait. For just 46 m/s I reach a PE of 296km at Catullus.

dWUZUrs.jpg

 

Before I reach Catullus, I set off the two relays. The two have then increased the AP to 100.000km, so they are not caught by Catullus. At the AP, I
then turned the two into a 90 degree inclination - each 250 m/s costs the maneuver. The relays will be sent to a high northern and southern polar orbit around
Gauss. I have to split the maneuvers, because I can only burn 240 m / s at a time (Ions). At the first braking I lower the orbit from 100,000km to 25,000km,
then 12,000km, etc. It is planned then a PE of 1,000km and a polar AP of at least 1,000,000km.

je91kJR.jpg

 

Here I had the opportunity to make some beautiful pictures of Gauss, Catullus and Tarsiss. 

h0in8ei.jpg

VxXr147.jpg


In the last picture, you can see that Catullus just throws his shadow on Gauss. At the edge of the shadow, Loki also just appears behind the planet.H32tm3y.jpg

 

But let us now continue with the mother ship. At Catullus I brake for 230 m/s and get an AP of 20.000km. I will try to get a lower orbit with aerobraking. Since I
am at the PE over 4000 m/s fast I can not dive very far into the atmosphere, just 260km at an atmosphere hight of 280km. Everything gets hot very quickly.
I start with an AP of 10,000 km. After the first brake maneuver I have 8.700km, it follows 7.980km, 7.232km, 6.637km, 6.030km, 5.407km, 4.864km, 4.385km,
3.962km and 3.574km. This is enough to not be caught by Tarsiss. I now increase the PE to 290km.

znX7Pt5.jpg

 

Finally, I put the claw on top of the lander to capture the unmanned Catulluslander.1wDt5Gu.jpg

Q8wht9l.jpg

Now it is waiting for the other vehicles to arrive. Meanwhile, I will bring the relays to the final orbit.

Today there are many pictures and boring maneuvers.

Soon it gets serious - we are slowly approaching the interesting part of the story. But one after anonther:

While waiting for the arrival of the other vehicles, the relays are brought to their final orbit. PE at 1.000km, AP at 2.000.000km. For an orbit they need 1 year and 155 days.

The Catulluslander is the first vehicle after the mothership arriving in the Gauss Sphere of Influence.
The trajectory fits quite well, I burn a small correction maneuver for 2.4 m/s to lower the PE at Catullus to 280km. For this maneuver I turned off 8 of the 10 LVN and the last two throttled to 10%. This way you can maneuver very precisely.

JGUgf2K.jpg

 

Then I planned a maneuver in the orbit of Catullus to slow down and adapt the orbit to the mothership. The brake maneuver needs 1.441m/s.

25X1DVP.jpg

fG6vVOX.jpg

 

After this maneuver, I changed the inclination by 0.9 degrees and accelerated at the AP for 84 m/s to reach an intercept with the mothership.

7voEncP.jpg

yoITwth.jpg

 

With the claw monuted on the mothership I have then catches the Catulluslander. Now the Catulluslander can be manned and everything is prepared. But I can not land yet, because the other vehicles have already arrived and first have to be brought to their Orbits.

(Thre are 2 solar eclipses simultaneously on Gauss)

v9BZfcs.jpg

peJh7eo.jpg

 

The Survey probe is next.

LChV8Lr.jpg

 

In the transfer stage are still 294 m/s left. This I use to slow down at Gauss and get an orbit with an AP of 108.000km.

eNWWAnh.jpg

 

Then I dropped the burned out stage. From now I have still ion drive available.

JQoxQZd.jpg

 

At the AP, I then planned a maneuver for 405.9 m/s to reach a polar orbit at Catullus. There I then lowered the AP to 1.500km to make an Orbital Survey.

hNsh5SD.jpg

(Again 2 solar eclipses on Gauss, which does not seem as rare as I thought)HU8Q6F3.jpg

 

Meanwhile the Tarsiss SSTO has already arrived.

mBGydz8.jpg

 

It has braked at the PE of Gauss for 326.4 m/s and had then also at Catulluss a PE of 280 km.

MJYrwbA.jpg

upVXKwF.jpg

 

At Catullus, the inclination was adjusted (36 m/s) and braked for another 560 m/s to reach a stable orbit. 

bTWOijb.jpg

The Tarsiss SSTO remains here in a parking orbit until I was on Catullus.

All vehicles have now arrived and in a stable orbit. When I wanted to finish the game, I once again checked if interesting offers are available.

God has that guy luck. Of course, I take him with me.

Now we will land, nothing can stop us now.

I am separating the lander from the mothership...

wCTef1o.jpg

 

... lower the AP, aim to a nice spot and lower the PE to 100km. Then I release the transfer stage, unfold the heat shield and activate the airbrakes.

iDJB5Ja.jpg

(I have been waiting extra with the landing to I have all the bodies in the background)

eAGyVT7.jpg

 

Shortly before entering the atmosphere, the lander still has a surface speed of 3120 m/s.

WnC9eJe.jpg

 

Somewhere at 200km then the entrance effects come. Everything remains beautifully stable. The entry into the atmosphere is by far not as extreme as with Eve. At 115km the speed has already decreased to 1524 m/s. The maximum negative acceleration is 1.8 G. Here I have already done some scientific research.

BCooi58.jpg

 

At about 45km the parachutes release and I slow down to 223 m/s.

HXSbq8U.jpg

 

Now the atmosphere really becomes a soup. The planets disappear in the fog.

boJoL5R.jpg

 

At 7000m the weather clears up again. The Lander has reduced its speed to 100 m/s.

O7b2skr.jpg

 

At 2750m the parachutes then open completely and the lander reaches its landing speed of 6 m/s.

4VGfASu.jpg

 

LANDED

ncxVo1w.jpg

 

Science is first collected, then the devices are reset, and investigations are started again. Collect all and...

2JJygrh.jpg

 

...say CHEESE...(In the background are Gauss, Tarsiss and the small moon is Loki)

DQIHWA8.jpg

 

All Kerbals go back on board and then ... Oh my God!

Ah01N4Q.jpg

 

No panic. The fireworks were planned (Jeb insisted on a firework). I have attached all the ladders, parachutes, the airbrakes and scientific instruments to
decouplers. Before the start, these must be discarded in order to save weight.

gRXpbNS.jpg

 

Here I save first, it can always go something wrong. Before the launch I put the SAS on Surface and Radial out. So that I can see better
if the tanks are empty, I have also brought them to the screen. Shortly after the start, the landing legs are still decpoupled.

dosBLVb.jpg

 

I switch the SAS to Prograde and tilt it slightly to the horizon to reach a Gravity turn. Since I must be very careful. If I
tilt her too much, she would flip around. (As a tip for all who bring a similar rocket here, I recommend elevons or winglets
to keep the course better. Vector engines would also go, but since the gravity is not so high, one does not necessarily need)
The first stage is empty and we no longer need the Balast.

jltxrcm.jpg

 

At an altitude of 20km, the next stage is empty and is discarded. The rocket also does not lean too much - does not look bad so far.

xSWZPOk.jpg

 

Here I have time to make a nice picture of the ascent.

pR9PqvO.jpg

 

Shortly after reaching the 67km mark, the next stage is empty. The flight curve is a bit too steep, I wanted to have here
about 45 degrees. Therefore, I do not load again, it will work. At an altitude of 100km and an AP of 200km I throttle the rocket to 1/3 thrust to flatten the curve.

QmQ8uNf.jpg


When the AP reached 280 km, I turn the rocket to the horizon and burn the rest of the stage and throw it off. Then I set at the AP
a maneuver to bring the PE to over 280km - 1300 m/s.

Done. Stable orbit over 280km and still 1621 m/s dV left. At my best test I still had more than 2000 m/s.

Now I can go back to the mothership.

I am planning a rendezvous with the mothership...

...and transfer all scientific experiments and the crew except of Jeb. Then I refuel the Catullusrocket and undock.

Because I still need to catch the poor stranded Kerbal.

After that, we go back to the mothership, fill the rest of the fuel into the lander, transfer the entire crew to the
mothership and discard the rest of the catullus lander forever.

Now I have to bring the Survey Probe into a polar orbit around Tarsiss. For a total of 610 m/s I get a nice polar orbit.

In the orbit of Tarsiss I lowered the PE to 110km and could thus slow down in the atmosphere very nicely. Then I increased the
orbit and performed Orbital Survey Scan.

Now I know where I can refuel the Tariss SSTO with ISRU and plan a docking maneuver with the mothership.

I take over the team and head to Tarsiss. For just 36 m/s I get an intercept. Where are my pictures? I think because I forgot to press F1.:P

In any case, I lowered the PE at Tarsiss to 115km and reached again with aerobraking an orbit. Then I increased the PE again to get a stable orbit.

The Tarsiss SSTO is now waiting for its deployment.

Before I land I mark all biomes.

Then I change the orbit to land near the biome "Atoll".

Next, I lower the PE to 100km for aerobraking.

When entering the atmosphere, I set the SAS on Surface and Radial out to effectively brake.

The descent continues forever so I set the SAS to Radial in to speed up.

The low gravity is one of the main reasons for this. Then at least we have time to take pictures.

Since I have far too much wings I can land only when I am slower than 10 m/s, otherwise, I pluck off and am back in the air. I open all cargo bays to have as much drag as possible.

Immediately after landing, I begin with scientific investigations. To reset the Mystery Goo unit, I have to move the front chassis. By the way - I do not know why I have one - at 10 m/s landing speed.:P

Then I set the flag and make a reminder photo. Tarsiss is really a gem. The crew goes back on board and I refuel again with ISRU. 14 days lasts, I only have the small Convert-O-Tron. I remember the ISP for this altitude - ISP at 3571m 160 LVN, 267 Spark. This could be important later, if I want to leave the moon again.

Since the Methanlake is nearby, I also want to join this biom. So I release the brakes, roll down the hill and take off without doing anything at 15 m/s. Much to much wings.

I glided so beautiful there for and when I reach the lake... NOOOOO!

the plane drowned. Now I have SSTU- boat:/

I quickly do all scientific experiments and activate all the engines I have. The ISP is now only 80 for the LVN. Thank goodness, the Spark here still has 250. At 13.5 m/s, I'm back out of the lake. Much to much wings ...:huh:.I'm looking for a place on the shore to refuel, this action has quite a lot of fuel consumed. At the same time I can still visit the Highland and the Midland Biome.

Here you can also see how I stowed the drill in the Cargo Bay. In order to drill, I must move however the rear chassis.
