This figure shows an example spectrum plot generated using PyHAT. The black line is a laser induced breakdown spectroscopy (LIBS) spectrum of a basalt sample. The colored lines show the baseline estimated using several different algorithms.

Computer simulation of two planets undergoing a giant impact that results in a merger (accretion). The larger (target) body is one tenth the mass of the Earth and the smaller (impactor) body is 70% the mass of the target. The planets are colliding at 1.08 times their mutual escape velocity, which equates to 3.63 km/s.

Computer simulation of two planets undergoing a hit-and-run giant impact. This style of collision comprises around half of the giant impacts expected to occur during the latter stages of Solar System formation. The larger (target) body is one tenth the mass of the Earth and the smaller (impactor) body is 70% the mass of the target.

Computer simulation of two planets undergoing a disruptive giant impact. Disruptive collisions are not expected to be common in Solar System formation and due to numerical effects, the amount of disruption shown here is likely overestimated. The larger (target) body is one tenth the mass of the Earth and the smaller (impactor) body is 70% the mass of the target.

Flyover of Valles Marineris, the "Grand Canyon" of Mars, highlighting two analysis-ready datasets provided by USGS. The canyon is more than 4,000 km (2,500 miles) long and up to 7 km (23,000 ft) deep.

In this demo, you will learn how to create a custom projection in ArcGIS Pro, using data that is not located on Earth. For this example, we will use the Lunar Reconnaissance Orbiter (LRO) Wide Angle Camera (WAC) mosaic of the Moon, and create custom polar and equatorial projections.
