How to use Solar Walk - The Missing Manual
R.A. Ross write:
Solar Walk will provide you with a landscape-view-only, realistic scale model of the Solar System. If you might enjoy manipulating these 30 celestial objects and the space-time between them as if you made the Universe, this is definitely the app for you.
The app always starts on Earth. The first step is to touch 1 of the 30 objects depicted in this app, and the name of your selection will be shown inside the button at the bottom of the screen. To zoom in close to that object, touch that button or the object itself. The second step is to either rotate around the selected object by finger-dragging, or to zoom in or out by spreading or pinching. Zoom out all the way and you will see the Sun's place among some stars created to represent our galaxy.
All 30 objects are labeled with their name and orbital path, both colored to match each object. All labels and control buttons will disappear if you touch the screen where nothing is selectable, or after 10 seconds of not touching the screen. As you approach the ecliptic plane, the 8 planetary orbits disappear. Once you can see the surface of an object, its name disappears. Get closer to Venus, Mars, our Moon, and Earth, and the names of several surface features (capital cities on Earth) become visible. Plus, there is a large arrow floating in space, pointing to you on Earth.
The app always starts with a forward clock speed of about 4.3 minutes per second. To simulate going forward (limit: 7000 AD) or backward (limit: 3001 BC) in time, touch 1 of the 5 units in the digital clock, and then swipe/drag either up or down on the little lines along the screen's right edge. The clock digits will then reflect the altered flow of time, and then you can either look around like usual, change the flow of time again, or go back to the present.
You can change the flow of time again, or even bring it to a standstill, either by swiping/dragging up or down on the little lines some more, or by touching a different unit in the clock. To go back to the present, touch the "now" button, located next to the clock. As time speeds up, objects with the smallest orbits will seem to disappear because they will be the first objects moving too fast to see. If you continue to speed up time, objects with larger orbits will disappear. Even an object you are zoomed-in on can vanish in this way.
1. Upper right corner - the "analog clock" button hides/unhides both the time and the little lines along the screen's right edge. The date can also be hidden if the digital clock is first set to "now".
2. Upper left corner - the letter "i" button zooms the viewer in toward the lit side of the selected object while pausing the time, and it opens an information box containing up to 4 vertically scrollable columns of relevant facts and images. Switching columns: iPhone/iPod touch, arrow button; iPad, scroll horizontally inside the box. To reverse the interface changes which the "i" button made: iPhone/iPod touch, "x" button; iPad, touch outside of the information box.
3. Lower left corner - the "orrery" (or model of the Solar System) button alters this fact: the planets are very small when compared to the Sun, and very far apart, so it takes time to find one. This button greatly reduces the distances between the planets while greatly increasing their sizes, and it also forces the Sun to be the center of any rotation or zooming. To reverse this change-of-scale, touch the "x" button or an object.
4. Lower right corner - the "list" button displays 3 more control buttons: Stereo, Music, and Movies. "Stereo" switches the app between 3-D (for use with red/green 3-D glasses) and non-3-D modes, while removing the "i" button. "Music" mutes/unmutes a wordless and space-y Siberian music album called "Solar Walk"; this muting is all the app remembers when you close it. "Movies" plays a 100-second video showing a size comparison of every object, excluding all moons but ours.
Included in this Russian app: the Sun, the 8 planets, Pluto (which is 1 of 5 dwarf planets), 20 (of the more than 170) moons, and 4 inaccuracies: Hyperion is not spherical (see its information box), Venus' surface is not visible because of its thick atmosphere, Pluto's surface is not identical to Ganymede's (see planetpixelemporium.com) for it is unknown, and the surface shadows of objects do not extend out into space.
Shown on Earth's surface are the locations of 124 (of the more than 250) capital cities of countries, regions, and territories, though 6 are not names of capital cities: Colombo, Dar es Salaam, Koror, Tarawa, Fongafale, and Victoria. Shown orbiting Earth are 10 (of the more than 6,500) man-made satellites: Aqua (aka EOS PM-1), CORONAS-Photon, Daichi (aka ALOS), Envisat, ERBS, Hubble (aka HST), ISS, SEASAT, Suzaku (aka ASTRO-EII), and UARS. Touch them to see their identity.
*THINGS TO TRY*
1. Check out the weird surfaces of Tethys and Miranda, and the detail of Earth, where the cities are lit at night and, whenever you speed up time, clouds move noticeably across the surface.
2. Select a distant moon. Get its planet to show up behind it. Get some of its other moons onscreen, too, or maybe some other planets and the Sun. Take a screenshot and enjoy!
3. Select an object other than Pluto. Select the orrery button. See how big you can make Pluto onscreen while using it to create a total eclipse of the Sun. Not easy!
4. Select an object other than the Sun. Speed up time so the stars are slowly moving. Zoom out all the way, view the galaxy edge-on and zoom in slowly. Watch as the dark clouds of the background galaxy image fade in where the bright stars representing the galaxy fade out. Once they fade out, stop zooming and drag your finger around. Stars will be far in front of and behind the Sun. Now zoom in until the stars begin to slowly move again, then stop zooming. The stars will be moving independently of each other far behind the Sun.
Cool...but...forgot Neptune's Moons
C'mon guys. Please add in Neptune's moons and I'll give it 5 stars. Kind of a silly oversight.
Great app with small bugs resolved
REVISION TO PREVIOUS REVIEW.
Bug was resolved after reinstalling application. No issues with display or dialog boxes.
It is obvious the developers put a lot of thought and effort into this elegant application. I love this app and use it now for "Science Night" at home with my seven year old daughter.
