What are 
Solar System Treks?

The Solar System Treks are online, browser-based portals that allow you to
visualize, explore, and analyze the surfaces of other worlds using real data
returned from a growing fleet of spacecraft. You can view the worlds through the
eyes of many different instruments, pilot real-time 3D flyovers above mountains
and into craters, and conduct measurements of surface features. The portals
provide exciting capabilities for mission planning, planetary science, and
public outreach.

VIRTUAL REALITY LIBRARY

You can use the “Experience TrekVR” tool in many of the Trek portals to create
your own virtual reality flyovers of terrain that interests you. We’ve also
created a list of pre-made VR flyovers of some of the more popular sites to help
get you started in your VR explorations. Use your smart phone to scan the QR
code associated with each flyover, put your phone in a pair of
cardboard-compatible goggles, and start flying. Keep an eye on this page! We’ll
be updating it with new flyovers.


Apollo Landings | Possible Landing Sites on the Moon | Great Landscapes of Mars
| Views of Vesta | Active Geology on Ceres | Great Landforms of Mercury

These flyovers use data from the Wide Angle Camera aboard the Lunar
Reconnaissance Orbiter to provide a broad view of the fascinating geography that
led to these sites being selected for the first stages of human exploration on
the Moon. For each site, we provide a screenshot map from Moon Trek showing the
flyover path marked in yellow and a red X marking the landing site. We also
include a QR code or browser link for you to use in viewing the flyover.

In January 2018, NASA conducted a workshop to discuss and identify potential
future landing sites on the Moon for future missions. For more information see
https://lunar-landing.arc.nasa.gov. Here are VR flyovers for some of the
highlighted sites. For each site, we provide a screenshot map from Moon Trek
showing the flyover path marked in yellow. We also include a QR code or browser
link for you to use in viewing the flyover.

From the solar system’s tallest mountain to its deepest canyon, Mars is a world
of epic landforms. We explore some of them here. For each site, we provide a
screenshot map from Mars Trek showing the flyover path marked in yellow. We also
include a QR code or browser link for you to use in viewing the flyover.

Vesta is the second most massive object in the asteroid belt, after the dwarf
planet Ceres. It is considered to be a protoplanet, a kind of planet embryo and
an example of one of the building blocks for larger planets. Its shape is not at
all spherical, after massive impacts by smaller asteroids blasted away much of
the southern part of the world. Vesta was studied in detail by NASA’s Dawn
robotic spacecraft. For each site, we provide a screenshot map from Vesta Trek
showing the flyover path marked in yellow. We also include a QR code or browser
link for you to use in viewing the flyover.

Located within the asteroid belt between the orbits of Mars and Jupiter, the
dwarf planet Ceres measures 945 km across. Ceres seems to have a rocky core
surrounded by a thick mantle of ice (and perhaps even some liquid water, beneath
a crust rich in clay and carbonates. There are many signs of active geology on
Ceres. The role of lava on Ceres was played by water, erupted as liquid from
below and building mountains of ice. Ceres was studied in detail by NASA’s Dawn
robotic spacecraft. For each site, we provide a screenshot map from Vesta Trek
showing the flyover path marked in yellow. We also include a QR code or browser
link for you to use in viewing the flyover.

Mercury is the smallest and innermost of the major planets in our Solar System.
Its close proximity to the Sun results in scorching daytime temperatures of 700
degrees Kelvin. Yet permanently-shadowed craters near the pole contain deposits
of ice! In some ways, the surface of Mercury resembles that of our Moon. But
Mercury also has many unique and spectacular landforms. Using data from NASA's
MESSENGER mission, which studied Mercury from orbit in 2011-2015, we will
explore some of these amazing features. For each site, we provide a screenshot
map from Vesta Trek showing the flyover path marked in yellow. We also include a
QR code or browser link for you to use in viewing the flyover.

 * Calculate Distance
 * Calculate Elevation
 * Calculate Sun Angle
 * Trek Map Services

Virtual Reality

Have Google Cardboard or a set of VR goggles? Open the Tools panel to draw a
path to float along with full 360 views, or get started with some of our
favorite fly-alongs in our Virtual Reality Library. If you are unfamiliar with
QR codes, watch the short video below to see how it works with Trek Virtual
Reality.

Currently not available in Titan or Icy Moons Trek.



3D Printing

Pick a feature or area that you would like to 3D print, and we'll give you the
file! A few of the portals - Bennu, Ceres, Ryugu, and Vesta - have pre-generated
3D print files of the entire globe. Just go to the Menu situated in the
top-right corner of the Trek portal and select "Download 3D Globe Print
File(s)".

3D Visualization

Explore the Moon, Mars, and Vesta in 3D. Spin our moon, the Red Planet or the
huge asteroid around its axis, orient it whichever direction you want, and
approach from any angle. Change the projection or view by clicking the globe or
'3D' button located at the bottom-left of any Trek.

Calculate Distance

Draw a straight line, a polyline, or freehand your own proposed rover traverse,
and we'll give you the distance. It may look tiny on the map, but you'll be
amazed how huge (or small) these celestial bodies are. Draw your line, polyline,
or freehand polyline and let us do the calculation.

Calculate Elevation

Draw a line, polyline, or freehand polyline and see how the elevation changes.
We extract the elevation profile from a digital elevation model (DEM) of the
terrain and give you the results in an interactive graph. If you would like to
see numbers in a convenient format, simply export the elevation profile to a
.csv file.

Note: The GIF shows an older version of our elevation profiler. The current one,
which you can access on the respective Trek sites, works in the same way AND has
a nifty zoom feature. Try it out and let us know what you think in the Feedback
link below.

Calculate Sun Angle

Select 'Calculate Sun Angle' from the Tool menu then place your marker. Choose
the start and end dates and times, set your interval and submit. (The default
interval is set to 50 and will display 50 data points interspersed equally
between the start and end time. The lower the number, the less accurate the
results because the less frequent the readings.) The results are given in a
graph showing the Elevation and Azimuth of your placed marker to the sun.

Trek Map Services

Most of the map layers shown from Treks are available through OGC RESTful Web
Map Tile Service (WMTS). Through this service, you can display map layers from
Treks on your software system. Read through our documentation at WMTS Layer
Services.
