This is a log of my Grand Tour style journey which is in progress. I did it in the DCIV vessel I made, which is available on OrbitHangar, [ame="http://www.orbithangar.com/searchid.php?ID=3849"]here[/ame].
Feel free to comment on what I've got so far - it -is- a mission in progress.
I'll grant, the times are a bit off - I started the mission from a standard .scn, so it's in 2001, instead of 2070-ish, which is the technical timeframe I'm sort of working with as far as my ships go. Nonetheless, take it at face value, and enjoy!

Captain's Log:
MJD 52056.4041
Started burn for Venus today, Sunday May 27th, 2001. Current loadout is 99.8%
main fuel in the water tanks, three XR2s of the IC series, 640t Naquadah fuel

Final insertion burn completed. Fuel remaining is 75%, PeA is now 1.9Mm,
Altitude is 4.125Mm, Orbital Ecc is .4056. Current plan among command staff is
to follow orbit to apoapsis, complete a final burn using translational
thrusters, and move the periapsis into the atmosphere to allow for a slow
aerobraking.
MJD 52176.4583
Initial circularization burn begun near apoapsis of 12751km. Burn is expected
to bring periapsis down to 110km altitude to take advantage of the Venusian
atmosphere for aerobraking.
MJD 52176.4711
Initial circularization burn completed. Current PeA is 110km. 74.5% fuel
remaining. Current ApA 12733km.
MJD 52176.5466

MJD 52176.9516
Fifth atmospheric interface at 200km.
MJD 52176.9862
Apoapsis reached. Fifth aerobraking pass brought our apoapsis down to 549.1km.
Orbit will be circularized at 550km.
MJD 52177.0529
Orbit circularized. Orbital inclination is near polar, 85.39 degrees. This will
allow a detailed survey of Venus' surface using long-wave scanning.
Eccentricity is 0, SMa is 6602km, LAN is 295.22 degrees, LPe is 295.22 degrees,
AgP is 0 degrees. Crew will take a day of celebration and rest before beginning
outfitting of IC-02 for its mission to the Venusian surface. Total time for
Venusian rendezvous is 120:15:34:16.
MJD 52177.0529 Notes
The IC-02 is a specially outfitted XR2, designed to withstand the heat and
atmospheric pressure on Venus. Its SCRAM engines have been modified to operate
at significantly lower speeds, though this cuts their effectiveness at higher
Mach numbers. The engines are also injected with an oxidiser (carried in a
tank in a sealed and pressurized hangar bay), to allow the atmosphere to be
used as reaction mass for the engines. This means that the normal issues with
a Venus landing, i.e. ineffectiveness of standard rocket engines, is strongly
mitigated. The modified SCRAM engines can produce enough thrust for the XR2 to
take off from the surface of Venus and reach the higher atmosphere, at which
point rocket engines can be engaged to normal effect. All surfaces except the
engines exposed to outside air are coated with an acid-resistant polymer.
This polymer can withstand temperatures up to 1000C, which means that the entry
of the ship will have to be shallower than the normal, and the pilot is
encouraged to abort the mission to orbit if any deterioration of the coating
occurs. The engines themselves are coated with a heat and acid resistant alloy,
which is unfortunately too dense to be used in normal operations. The pilot is
protected by a cockpit and life support system at a slightly higher than normal
pressure of 1.5atm. While the pilot will be unable to leave the ship to permit
setting foot on the surface, they will still be one of the first humans to land
on the surface of Venus and take off again.
MJD 52177.6721
IC-02 outfit has been completed. All seals except for the crew cabin are
prepared, and the ship is ready for pressurization.
MJD 52188.2494
IC-02 pressurization begun. Undocking and deorbit burn will occur on the next
orbit. The crew is inside the IC-02, all instruments are activated and ready
to be powered by the IC-02's APU. A second load of APU fuel has been put on the
ship to allow for a longer running of the instrumentation. Bay area 1 has been
loaded with an extra 3000kg of coolant, to allow venting since radiative heating
will be far less effective due to the dense atmosphere and surface temperature.
MJD 52178.2971, 07:07:06 UT
IC-02 undocks. Ship will bring periapsis down to 200km and circularize at that
point. Commander Toma Feodor reports all systems normal. Pilot Ilse Vita is at
the helm, and science officer Pavel Matej is on board as the third crew member.
SciO Matej will be conducting the experiments remotely once on the surface,
taking some of the most accurate measurements of Venus' surface ever as well
as taking real color pictures. A specially-designed UAV mounted to the top of
the IC-02 will do exploration of the surface in a 30km radius to allow for a
wider range of measurements. Planned landing location is near the south pole
of Venus, but Feodor has been instructed to choose his landing spot based on
the amount of sunlight on the surface.
MJD 52178.2971, 09:31:50 UT
Cmdr. Feodor has reported that the IC-02's orbit has been circularized at
199.9km. SciO Matej reports that the terminator is closer to the south pole,
therefore the landing will be planned near there.
MJD 52178.4274, 10:15:23 UT
Deorbit burn. PeA will be dropped to 90km. This is calculated to allow for
sufficient drag to bring the ship the rest of the way down.
MJD 52178.4277, 10:15:53 UT
Deorbit burn completed. PeA is 90km, orbital speed is 7177m/s.
MJD 52178.4443, 10:39:51 UT
Entry interface at 140km. Attitude hold program set to +40 degrees. APU will not
be engaged until necessary, to conserve fuel.
MJD 52178.4525, 10:51:37 UT
Pilot Vita reports all systems nominal. APU engaged, attitude hold program
operating within specified parameters. Radiator is expected to be stowed for
the remainder of the mission, until orbit is achieved again.
MJD 52178.4544, 10:54:17 UT
Pilot Vita reports all systems nominal. Thermals on the skin of the ship are
being held at 550C on the nosecone, 455C on the wings. Coolant temp 33.2C,
deceleration is -6.4m/s and rising, DynP is 11.8kPa, altitude 91.22km.
MJD 52178.4586, 11:00:22 UT
Pilot Vita reports all systems nominal. Thermals on the skin of the ship are
being held below 600C on the nosecone, below 500C on the wings, well within
operational parameters. Coolant temp 39.0C, deceleration is -5.81m/s and steady
within .1m/s, DynP is 16.6kPa, altitude 86.43km. Convection currents have
already caused a far longer glide time than originally expected, and ship's
SciO, Lieutenant Commander Fulton Reyes is studying the possibility of an
equatorial landing rather than a polar one, as consumables on IC-02 would
not last a glide to the North pole of Venus as well as a full duration mission.
MJD 52178.4635, 11:07:25 UT
Pilot Vita reports all systems nominal. Thermals on the skin of the ship are
being held well below previous readings, and speed is being bled off. Current
orbital speed 2983m/s, current altitude is 85.81km. Coolant temperature 45.8C.
MJD 52178.4651, 11:09:48 UT
Pilot Vita reports all systems nominal. Coast phase is entered at a constant
15 degree AoA. Radiator will be deployed with a close eye on the dynamic
pressures on the ship. Crew concurs with the analysis that the radiator can
be safely deployed at this altitude and speed, and that the acid content of the
atmosphere is not significant at this altitude to warrant caution against a
breach of the protective coatings.
MJD 52178.4671, 11:12:41 UT
RCS fuel at 75%, 200.9kg APU fuel remaining. Pilot Vita reports all systems
nominal.
MJD 52178.4738, 11:22:17 UT
RCS fuel at 72.8%, 196.2kg APU fuel remaining. APU was shut down to conserve
fuel after the radiator was deployed and it was ascertained that minimal RCS
thrust would be all that would be required to maintain attitude. Pilot Vita
reports that she will be taking manual control of the ship to begin turning
back to proper course. Thermals are still well within tolerances, and the
current speed of 1800m/s is not expected to heat the skin of the ship beyond
what has been experienced thus far as long as a slow descent rate is maintained.
MJD 52178.4809, 11:32:33 UT
Pilot Vita reports all systems nominal. Thermal convection currents in the upper
atmosphere were far higher than originally expected and measured. As such, glide
distance was longer than expected, and the mission profile has changed to an
equatorial landing site near Ilithyia Mons with approval of ship's head SciO.
Radiator stowage begun. Coolant temperature is 38.6C. Once on the surface, IC-02
will use its stowed coolant to keep its systems cooled properly.
MJD 52178.4945, 11:52:01 UT
Pilot Vita reports all systems nominal. Current airspeed is 100m/s, altitude
50.22km. Atmospheric density at this altitude reads 1.405kg/m^3, which is close
to Terran sea level.
MJD 52178.5291, 12:41:56 UT
Pilot Vita reports all systems nominal. Current airspeed is 75.5m/s, altitude
25.22km. Atmospheric density is 14.33kg/m^3 and rising.
MJD 52178.5824, 13:58:37 UT
Pilot Vita reports all systems nominal. Current airspeed is 25.1m/s, sink rate
currently -3.04m/s. Outside air temperature is 438.8C at an altitude of 4.34km.
Coolant temperature is 57.4C, DynP is 15.0kPa. Atmospheric density is
51.88kg/m^3.
MJD 52178.6015, 14:26:13 UT
IC-02 has landed. All systems nominal. Crew will live inside IC-02 for the
entirety of the mission, which is expected to last 12 hours. Atmospheric
density is 64.991kg/m^3. Static pressure is 9.199MPA, OAT is 477.8C. APU is
being refuelled from internal stores, and disposable coolant is being used to
cool the ship.
MJD 52178.6066, 14:33:30 UT
SciO Matej reports that experiments are being deployed, and the ZPE UAV,
designation ZPE-22, has been undocked from the top hull.
MJD 52178.6151, 14:45:45 UT
ZPE-22 takes off from Venusian surface, beginning its automatic survey program.
Cmdr. Feodor is at the remote controls. The propellor-driven plane is noted to
be extremely efficient, beyond its original specifications.
MJD 52178.9124, 21:53:51 UT
ZPE-22 lands near the IC-02 after completing its survey mission. MET 7:08:07 to
initial wheel stop. ZPE-22 is being slowly taxiied the 1km distance back to the
IC-02. Cmdr. Feodor reports that the ZPE-22 performed well, and that a
propellor-driven ship design may be far more fuel efficient than any chemical
combustion engine which could be derived, for future Venusian exploration.
MJD 52178.9412, 22:35:20 UT
SciO Matej reports that he is beginning to stow all experiments in preparation
for takeoff. All experiments performed within tolerances, and no failures were
noted for the duration.
MJD 52178.9501, 22:48:09 UT
Experiments have been stowed. Final measurements and lockdown in preparation
for takeoff have begun.
MJD 52179.0180, 00:25:58 UT
IC-02 ready for takeoff. Soon after, Pilot Vita activates telemetry readings
from the IC-02, but cuts radio contact after a brief message that takeoff will
be very dangerous, and that callouts will only distract her.
MJD 52179.0180, 00:47:15 UT
IC-02 has achieved a 308.1x550 orbit. Pilot Vita reports in, apologizing for her
earlier statement. She stated that "it was like trying to take a rocket ship
through the ocean", and that future landings on Venus should use specialized
designs. Debriefing and future planning will occur upon docking.
MJD 52179.0251
Cmdr. Feodor reports that the atmosphere inside both the IC-02 and the pressure
hull is being slowly vented to normal pressures, to wait for the rendezvous.
In the tanks, 20% main fuel is remaining after topping off the RCS tanks via
cross-feed, and there is 8% of the LOX remaining to feed the modified jet
engines. This will allow for a slow, minimal-fuel rendezvous, and the crew of
IC-02 as well as the SPD-01 command staff agree that this fuel conservation
effort is acceptable, given the long range nature of the SPD-01's mission.
MJD 52183.4306
IC-02 Rendezvous with SPD-01. Pilot Vita reports commencement of docking
maneuvers starting at 12km out.
MJD 52183.4659
IC-02 opens its nosecone in preparation for docking.
MJD 52183.4699
Hard dock to dock 3 on SPD-01. Congratulations to the crew of IC-02 on their
mission to Venus.
MJD 52183.5229
Crew debrief of IC-02. All crew members enjoyed the mission immensely, and feels
that much was learned simply from the descent, experiments on the surface
notwithstanding. SciO Matej states that soil and atmospheric samples at pressure
were brought up from the surface, which will be transfered into the SPD-01's
laboratories for work en route to Mercury. Other valuable data included accurate
pressure readings, temperature readings, detailed survey of the 100 square
kilometers around Ilithyia Mons, and possibly most importantly, first-hand
experience on flight operations in such a thick atmosphere. Pilot Vita
recommends that a swept-wing aircraft would be a far more ideal design for
flying in the atmosphere of Venus. The mass of IC-02's environmental systems
was a boon for stability given the high winds, and the dense atmosphere gives a
large amount of lift at far lower speeds than the Earth's atmosphere. Other
recommendations include improving the durability of the acid-resistant polymer
coating, due to strong heating, and perhaps a skid-style landing gear, since
landing velocity was roughly 14m/s. The extreme temperatures on the surface
were very near the thermal limits of the XR2's landing gear despite the
resistant coating, and a skid-style landing apparatus would be more durable in
this environment than a hydraulic system such as that which the XR2 uses. Also,
given the performance of the ZPE-22 UAV, a propellor-driven design for initial
takeoff would likely be more effective than the modified jet propulsion which
was used on this mission. Potential problems include a way to permit the
propellors to survive a re-entry as well as an ascent - the heat is less of an
issue than the dynamic pressures. Of note is that while the ZPE-22 survived
ascent itself, the propellor was mangled beyond repair due to the pressures of
ascent.
MJD 52183.5623
Initial preparations are being made for ejection to Mercury within the next
three orbits.
MJD 52183.5698
Course to Mercury has been programmed into the flight computer. Flight time is
expected to be 65 days. Current main fuel in the SPD-01 is 71.2%.
Feel free to comment on what I've got so far - it -is- a mission in progress.
I'll grant, the times are a bit off - I started the mission from a standard .scn, so it's in 2001, instead of 2070-ish, which is the technical timeframe I'm sort of working with as far as my ships go. Nonetheless, take it at face value, and enjoy!

already caused a far longer glide time than originally expected, and ship's
SciO, Lieutenant Commander Fulton Reyes is studying the possibility of an
equatorial landing rather than a polar one, as consumables on IC-02 would
not last a glide to the North pole of Venus as well as a full duration mission.
MJD 52178.4635, 11:07:25 UT
Pilot Vita reports all systems nominal. Thermals on the skin of the ship are
being held well below previous readings, and speed is being bled off. Current
orbital speed 2983m/s, current altitude is 85.81km. Coolant temperature 45.8C.
MJD 52178.4651, 11:09:48 UT
Pilot Vita reports all systems nominal. Coast phase is entered at a constant
15 degree AoA. Radiator will be deployed with a close eye on the dynamic
pressures on the ship. Crew concurs with the analysis that the radiator can
be safely deployed at this altitude and speed, and that the acid content of the
atmosphere is not significant at this altitude to warrant caution against a
breach of the protective coatings.
MJD 52178.4671, 11:12:41 UT
RCS fuel at 75%, 200.9kg APU fuel remaining. Pilot Vita reports all systems
nominal.
MJD 52178.4738, 11:22:17 UT
RCS fuel at 72.8%, 196.2kg APU fuel remaining. APU was shut down to conserve
fuel after the radiator was deployed and it was ascertained that minimal RCS
thrust would be all that would be required to maintain attitude. Pilot Vita
reports that she will be taking manual control of the ship to begin turning
back to proper course. Thermals are still well within tolerances, and the
current speed of 1800m/s is not expected to heat the skin of the ship beyond
what has been experienced thus far as long as a slow descent rate is maintained.
MJD 52178.4809, 11:32:33 UT
Pilot Vita reports all systems nominal. Thermal convection currents in the upper
atmosphere were far higher than originally expected and measured. As such, glide
distance was longer than expected, and the mission profile has changed to an
equatorial landing site near Ilithyia Mons with approval of ship's head SciO.
Radiator stowage begun. Coolant temperature is 38.6C. Once on the surface, IC-02
will use its stowed coolant to keep its systems cooled properly.
MJD 52178.4945, 11:52:01 UT
Pilot Vita reports all systems nominal. Current airspeed is 100m/s, altitude
50.22km. Atmospheric density at this altitude reads 1.405kg/m^3, which is close
to Terran sea level.
MJD 52178.5291, 12:41:56 UT
Pilot Vita reports all systems nominal. Current airspeed is 75.5m/s, altitude
25.22km. Atmospheric density is 14.33kg/m^3 and rising.
MJD 52178.5824, 13:58:37 UT
Pilot Vita reports all systems nominal. Current airspeed is 25.1m/s, sink rate
currently -3.04m/s. Outside air temperature is 438.8C at an altitude of 4.34km.
Coolant temperature is 57.4C, DynP is 15.0kPa. Atmospheric density is
51.88kg/m^3.
MJD 52178.6015, 14:26:13 UT
IC-02 has landed. All systems nominal. Crew will live inside IC-02 for the
entirety of the mission, which is expected to last 12 hours. Atmospheric
density is 64.991kg/m^3. Static pressure is 9.199MPA, OAT is 477.8C. APU is
being refuelled from internal stores, and disposable coolant is being used to
cool the ship.
MJD 52178.6066, 14:33:30 UT
SciO Matej reports that experiments are being deployed, and the ZPE UAV,
designation ZPE-22, has been undocked from the top hull.
MJD 52178.6151, 14:45:45 UT
ZPE-22 takes off from Venusian surface, beginning its automatic survey program.
Cmdr. Feodor is at the remote controls. The propellor-driven plane is noted to
be extremely efficient, beyond its original specifications.
MJD 52178.9124, 21:53:51 UT
ZPE-22 lands near the IC-02 after completing its survey mission. MET 7:08:07 to
initial wheel stop. ZPE-22 is being slowly taxiied the 1km distance back to the
IC-02. Cmdr. Feodor reports that the ZPE-22 performed well, and that a
propellor-driven ship design may be far more fuel efficient than any chemical
combustion engine which could be derived, for future Venusian exploration.
MJD 52178.9412, 22:35:20 UT
SciO Matej reports that he is beginning to stow all experiments in preparation
for takeoff. All experiments performed within tolerances, and no failures were
noted for the duration.
MJD 52178.9501, 22:48:09 UT
Experiments have been stowed. Final measurements and lockdown in preparation
for takeoff have begun.
MJD 52179.0180, 00:25:58 UT
IC-02 ready for takeoff. Soon after, Pilot Vita activates telemetry readings
from the IC-02, but cuts radio contact after a brief message that takeoff will
be very dangerous, and that callouts will only distract her.
MJD 52179.0180, 00:47:15 UT
IC-02 has achieved a 308.1x550 orbit. Pilot Vita reports in, apologizing for her
earlier statement. She stated that "it was like trying to take a rocket ship
through the ocean", and that future landings on Venus should use specialized
designs. Debriefing and future planning will occur upon docking.
MJD 52179.0251
Cmdr. Feodor reports that the atmosphere inside both the IC-02 and the pressure
hull is being slowly vented to normal pressures, to wait for the rendezvous.
In the tanks, 20% main fuel is remaining after topping off the RCS tanks via
cross-feed, and there is 8% of the LOX remaining to feed the modified jet
engines. This will allow for a slow, minimal-fuel rendezvous, and the crew of
IC-02 as well as the SPD-01 command staff agree that this fuel conservation
effort is acceptable, given the long range nature of the SPD-01's mission.
MJD 52183.4306
IC-02 Rendezvous with SPD-01. Pilot Vita reports commencement of docking
maneuvers starting at 12km out.
MJD 52183.4659
IC-02 opens its nosecone in preparation for docking.
MJD 52183.4699
Hard dock to dock 3 on SPD-01. Congratulations to the crew of IC-02 on their
mission to Venus.
MJD 52183.5229
Crew debrief of IC-02. All crew members enjoyed the mission immensely, and feels
that much was learned simply from the descent, experiments on the surface
notwithstanding. SciO Matej states that soil and atmospheric samples at pressure
were brought up from the surface, which will be transfered into the SPD-01's
laboratories for work en route to Mercury. Other valuable data included accurate
pressure readings, temperature readings, detailed survey of the 100 square
kilometers around Ilithyia Mons, and possibly most importantly, first-hand
experience on flight operations in such a thick atmosphere. Pilot Vita
recommends that a swept-wing aircraft would be a far more ideal design for
flying in the atmosphere of Venus. The mass of IC-02's environmental systems
was a boon for stability given the high winds, and the dense atmosphere gives a
large amount of lift at far lower speeds than the Earth's atmosphere. Other
recommendations include improving the durability of the acid-resistant polymer
coating, due to strong heating, and perhaps a skid-style landing gear, since
landing velocity was roughly 14m/s. The extreme temperatures on the surface
were very near the thermal limits of the XR2's landing gear despite the
resistant coating, and a skid-style landing apparatus would be more durable in
this environment than a hydraulic system such as that which the XR2 uses. Also,
given the performance of the ZPE-22 UAV, a propellor-driven design for initial
takeoff would likely be more effective than the modified jet propulsion which
was used on this mission. Potential problems include a way to permit the
propellors to survive a re-entry as well as an ascent - the heat is less of an
issue than the dynamic pressures. Of note is that while the ZPE-22 survived
ascent itself, the propellor was mangled beyond repair due to the pressures of
ascent.
MJD 52183.5623
Initial preparations are being made for ejection to Mercury within the next
three orbits.
MJD 52183.5698
Course to Mercury has been programmed into the flight computer. Flight time is
expected to be 65 days. Current main fuel in the SPD-01 is 71.2%.
