Lidar Measurements of Snow Falling from Martian Clouds
This image is of the Canadian-built lidar in operation with the cover open was acquired at the NASA Mars Phoenix Lander landing site on Sol 3.

The High Altitude Lidar Observatory (HALO) instrument head, which houses the lidar instrument, is installed onto the DC-8 airborne science laboratory at NASA Armstrong Flight Research Center in Edwards, California. The gold and blue casing holds the laser, optics, detectors, and electronics, which are at the heart of the lidar.

Aerosol data from the High Altitude Lidar Observatory (HALO), pictured here, will give mission scientists a better sense how Doppler Aerosol Wind Lidar (DAWN) is working and what its strengths and weaknesses are.

This image from NASA Phoenix Mars Lander of the Canadian-built meteorological station lidar, which was successfully activated on Sol 2 by first opening its dust cover, then emitting rapid pulses of light.

The High Altitude Lidar Observatory (HALO) system electronics and diagnostic tools are integrated onto the DC-8 airborne science laboratory at NASA Armstrong Flight Research Center in Edwards, California. The lidar system control electronics are on the right hand side of the rack. The large monitors on the left are used to display real-time images of water vapor and aerosol profiles, which are used by the science team to guide in-flight decisions and navigation. The compact HALO instrument head can be seen directly behind the electronics rack.

Researchers Anna Noe and Eric Altman check out the Doppler Aerosol Wind Lidar (DAWN), an airborne instrument that uses pulsed lasers to detect the movement of atmospheric aerosols such as dust or sea salt. In detecting those movements, it can profile wind vector — both speed and direction. Researchers are testing DAWNs capabilities during flights over the eastern Pacific.
A laser beam from the Canadian-built lidar instrument on NASA Phoenix Mars Lander can be seen in this contrast-enhanced image taken by Phoenix Surface Stereo Imager on July 26, 2008, during early Martian morning hours of the 61st Martian day.

Hrybyk More: A team of NASA scientists and engineers now believes it can leverage recent advances in a greenhouse-detecting instrument to build the world’s first space-based sodium lidar to study Earth’s poorly understood mesosphere. Scientist Diego Janches and laser experts Mike Krainak and Tony Yu, all of whom work at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are leading a research-and-development effort to further advance the sodium lidar, which the group plans to deploy on the International Space Station if it succeeds in proving its flightworthiness.

New maps of two recent California megafires that combine unique data sets from the U.S. Forest Service and NASA's Jet Propulsion Laboratory in Pasadena, California, are answering some of the urgent questions that follow a huge wildfire. These before-and-after USFS LIght Detection And Ranging (LIDAR) images from the 2014 King fire region in El Dorado National Forest, California are among new maps. They show a small section of the Rubicon River drainage basin, where fire damage was severe. Blue indicates ground level; lighter colors are higher. A road -- bordered by dense trees in the before image at left -- and part of a bridge are in the center, with the bridge appearing green. http://photojournal.jpl.nasa.gov/catalog/PIA19360

During their August 2023 Iceland field campaign, international science team members of NASA's VERITAS (Venus Emissivity, Radio science, InSAR, Topography, And Spectroscopy) mission prepare for lidar (Light Detection and Ranging) imaging of rocks at a study area. Lidar measurements of rocky terrain can provide information about the material, such as surface roughness. While the science team led by NASA's Jet Propulsion Laboratory gathered lidar data on the ground, their partners from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt, or DLR) carried out overflights to gather radar observations of the same study areas. By doing this, the team was able to ground-truth the radar data that will be used to help inform the science that VERITAS will do at Venus. VERITAS will peer through the planet's thick atmosphere with a suite of powerful science instruments to create global maps of Venus' surface – including topography, radar images, rock type, and gravity measurements – as well as detect surface changes. VERITAS is designed to understand what processes are currently active, search for evidence of past and current interior water, and understand the geologic evolution of the planet, illuminating how rocky planets throughout the galaxy evolve. https://photojournal.jpl.nasa.gov/catalog/PIA25839

CATS is used to study the atmospheric constituents that impact global climate. By gaining a better understanding of cloud and aerosol coverage, scientists can create a better model of the Earth's climate feedback processes.

The STS-64 patch depicts the Space Shuttle Discovery in a payload-bay-to-Earth attitude with its primary payload, Lidar In-Space Technology Experiment (LITE-1) operating in support of Mission to Planet Earth. LITE-1 is a lidar system that uses a three-wavelength laser, symbolized by the three gold rays emanating from the star in the payload bay that form part of the astronaut symbol. The major objective of the LITE-1 is to gather data about the Earth's troposphere and stratosphere, represented by the clouds and dual-colored Earth limb. A secondary payload on STS-64 is the free-flier SPARTAN 201 satellite shown on the Remote Manipulator System (RMS) arm post-retrieval. The RMS also operated another payload, Shuttle Plume Impingement Flight Experiment (SPIFEX). A newly tested extravehicular activity (EVA) maneuvering device, Simplified Aid for EVA Rescue (SAFER), represented symbolically by the two small nozzles on the backpacks of the two untethered EVA crew men. The names of the crew members encircle the patch: Astronauts Richard N. Richards, L. Blaine Hammond, Jr., Jerry M. Linenger, Susan J. Helms, Carl J. Meade and Mark C. Lee. The gold or silver stars by each name represent that person's parent service.
