Good luck Juno

Another update for Solar Explorer, and I’ve been extra busy this time.

Apart from a minor fix, I’ve added some more planet structures for Mars and Jupiter and tweaked the update I did last week for low resolution phones.

While adding the extra detail to Jupiter, I found out that we really don’t know much at all about the almost-red-dwarf in our Solar System.

NASA is planning to launch the Juno probe to Jupiter on the 5th of August to fill in the blanks, so I decided to pre-empt the launch and put Juno into space early, in Solar Explorer.

Juno has quite an interesting design with the three solar panels making it very distinctive, though I do have to wonder why solar power was chosen since Jupiter is so far from the sun.

As usual I’ve done my best to peel the thermal foil off the spacecraft so you can see what it looks like underneath.

For a spacecraft, Juno is also a 3D modeller friendly shape, unlike Voyager and Dawn which have bits poking out everywhere. The more shapes in a model, the slower it runs on the device, so it’s a lot of hard work for me to work out what to simplify to keep the speed up while keeping the overall appearance of the spacecraft intact. It would almost be easier to accurately model the spacecraft down to the smallest detail, but then if I did that, Solar Explorer would be all but unusable on the typical device.

In a future release I plan to include labels on various parts of the spacecraft to make Solar Explorer more informative, but for now it’s enough to push ahead with more spacecraft for the full version and expanding the detail on the planets and moons.

I also see that we’re starting to get more images from Vesta. Once we’ve got it photographed from all sides, I’ll update the Vesta model to look more realistic, but it may be a little while yet before we get the full picture.

In closing, I’d like to ask NASA to do me a favour and make sure Juno gets off the ground safely, or the only space it’ll ever see will be inside my model Solar System!

Dawn’s at Vesta, where’s the pics?

It was great to hear that Dawn successfully arrived in orbit around Vesta, however there’s one thing missing… the photos!

So far, all we’ve had is a couple of blurry shots as Dawn approached Vesta, and a single shot now that it’s in orbit.

According to the NASA watch, even though Dawn’s been captured by Vesta, it’s not in it’s final orbit. To get there, it’s using it’s ion thrusters and since since the communications dish is fixed, if Dawn turns away from the Earth, we can’t receive any pictures.

Dawn won’t be in it’s final orbit till mid August, so I guess we’re just going to have to wait until Dawn is good and ready to start sending back postcards.

I’m probably a little more eager than most to get the photos as I’m keen to update the preliminary Vesta model I put into Solar Explorer last week.

Dawn’s arrival

We should hear a bit later today whether Dawn has successfully entered orbit around Vesta. The reason for the delay is that the ion engines have been in use for some time as Dawn made it’s approach to Vesta, which has resulted in the communications dish being pointed away from Earth.

Continuing my personal celebration of Dawn’s arrival at Vesta, I’ve now updated Solar Explorer to include a model of Dawn, to complement the model of Vesta I released a couple of days ago.

 

 

Dawn over Vesta

There’s certainly a lot happening in space lately. The shuttle reitring, the Chinese talking about putting up a space station soon and Virgin Galactic’s first commercial flight getting closer.

One which interests me in particular is the arrival of NASA’s Dawn probe at Vesta, the second largest asteroid in the belt.

As it stands we have very little information about the Asteroids, just blurry telescope shots. Dawn will rectify that when it spends one year at Vesta before moving off to orbit Ceres, the largest Asteroid.

To celebrate Dawn’s arrival at Vesta, I have added a preliminary model of Vesta to Solar Explorer. It’s preliminary because it’s based on what data we have available, which is a rough shape estimate, which I’ve textured to look a bit like Deimos until we get better photos of Vesta from all sides.
