JamesG...idea is that it could move the panels and rotate them into the optimal direction...surely the rotational movement is just for the strolls every now and then.

Lets pretend that there were new efficient solar panels and this OBERON ship was build..how much would space geeks pay for a ticket to really fly/travel to Jupiter ..land on Callisto, Europe and Ganymedes ( + several of the 64 orbiters around Jupiter ) and Phobos for instance enroute back to Earth ?

If it took 405 days to complete it with 10 people strong team ???

If you had a change to take a 4 years long trip from there to Oberon near planet Uranus..would you go there ?

Would Neptunes Triton be of interest ? It could be made in under 5.8 years.

http://fi.wikipedia.org/wiki/Neptunus

How about Phoebe of Saturn..lot closer too; http://en.wikipedia.org/wiki/Phoebe_(moon)

Small gravity..easy to land on.

Or some of the 150 other moons; http://en.wikipedia.org/wiki/Saturn

With a good orbital techniques the Saturn would be only 220 days from Jupiter !

You may not have to pretend too much about the PV cells. Well depending on how you measure efficiency as 15% graphene solar cell printed on plastic could be a lot lighter for space purposes than 44% on a lump of heavy silicon.

I think a grand tour of the solar system as the Barclay card ads used to say would be priceless mind you have the wrong companions and be in too confined a space(especially if the loo rolls accidentally got dumped out the airlock) and it could be a new form of hell :wink: :twisted:

Right but it is work..it is not a marriage with a wrong person. They all must have a profound belief in science that something good is about to come from the voyage.

People were afraid of flying first...and some crashes scared them a lot...like a Fokker crash in Kansas where wood was banned as a building material for passenger plane. Also airline regulations were created.

Here is once more my in the orbit to be constucted " THE OBERON EXPRESS ". See how much bigger its "3rd" stage is compared to APOLLO !
When it is constructed at the orbit in LEO its already doing 28 000 km/h ...and earth rotates 30 km/s around the sun..it can propell itself to 13,2 km/s and each of the 5 pods into 2.9 km/s...so a pod after leaving orbit could be lauched to 54.1 km/s from the 51.2 km/s topspeed of the Oberon!

Pretty fast or what ?!

Feel free to ask if questions !

Here is another OBERON ship that makes the Saturn visit into just 505 days !

There are 2 moons suitable for speedy 30 km/s landing in the right time and orbit position; http://www.spacescience.org/education/e ... _1page.pdf

Prometheus and Pandora.

After some serious calculations I increased the mother ship size to 130 m spanning with 38 000 kg ( max 50 000 kg ) gross weight.

I also realized that you could make a greenhouse with oxygen and fresh vegetables producing plants in between the 8 boosters. Possibly the soil has to be netted so that a small times of weightlessness wont be throwing the dust and soil around the ship. Lotsa glass panels in between the boosters with pressure rating.

With a bigger mother ship you can also make roomier pods and reach higher cruise speed ( 50-55 km/s region ). :wink:

Pod ( STYX ) speed thus at max space carrier speed ( Oberon )reach 75 km/s in emergency.

Several doubts have been laid about mother ship being able to fly to LEO..here is a wing foil study for it. With very low RE number ( actual is 29-116 mio Re ).

Slowly ( IAS 100 km/h ) with high lift and low drag !

Intented OBERON ideas... :wink:

What if the back side of the solar panels are mirrors that project lite to solar panel that is inside the intended greenhouse..since the panels are movable that could project lotsa sun into a smaller area and provide lets say 8 m2 at 50 % efficiency at Saturn region...good enuf to keep some electronics on ?

That is 5.4 kW continuous..would it even heat the craft ?

I think you would be better off to "directly" use reflector/concentrators on both. Either using reflected light off the photo-voltaic array or otherwise capturing the "wasted" light from the likes of a solar sterling system. Going from solar photo-voltaic to whatever electric storage system to a light emitting array, all via lossy wires is probably the most inefficient scheme I can think of.

Right okay...

Here is a test model as a homebuilt of the MOTHER SHIP Solar Eagle !

QinetiQ is actually preparing to fly ( R/C model ) to 40 km with solar panels..this manned craft might just go to 12 km due to low rate panels available.

It could weigh just 60-80 kg empty.

Here is an example of the efficiency !

I had a funny idea...why not fly it to space all the way.

Could it be possible to fly a aeroplane /space ship to orbit and beyond...and come back neatly ?

In STAR WARS they fly a huge plane is space in EPISODE II.
