Launched on April 28, 2006, CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation) studies the role that clouds and aerosols play in regulating Earth's weather, climate and air quality. 3D Model created by Christopher M. Garcia at NASA/JPL-Caltech. Learn more about CALIPSO here
Launched in April 2006, CloudSat monitors the state of the Earth's atmosphere and weather with a sophisticated radar system. The instrument, jointly developed with the Canadian Space Agency, can predict which clouds produce rain, observe snowfall, and monitor the moisture content of clouds. 3D Model created by Kevin Lane at NASA/JPL-Caltech.

NASA's Hubble Space Telescope was the first astronomical observatory to be placed into orbit around Earth with the ability to record images in wavelengths of light spanning from ultraviolet to near-infrared. Launched on April 24, 1990, aboard the Space Shuttle Discovery, Hubble is currently located about 340 miles above Earth's surface where it completes 15 orbits per day approximately one every 95 minutes. 3D model by DigitalSpace Corporation for NASA.

The space station orbits low Earth orbit. It was first launched in 1998, and is now the largest artificial body in orbit and can be seen from Earth with the naked eye. The ISS consists of pressurized modules, external trusses, solar arrays and other components. The ISS serves as a space environment research laboratory where crew members conduct experiments in biology, physics, astronomy, meteorology, etc. The ISS maintains an orbit with an altitude between 330 and 435 km and completes 15.54 orbits per day.

Landsat 7 was successfully launched on April 15, 1999, from the Western Test Range of Vandenberg Air Force Base, California, on a Delta-II expendable launch vehicle. This joint NASA/USGS program provides the longest continuous space-based record of Earth’s land in existence. Every day, Landsat satellites provide essential information to help land managers and policy makers make wise decisions about our resources and our environment. 3D model created by Christopher M. Garcia at NASA/JPL-Caltech. Learn more about Landsat here.
Launched on October 28, 2011, Suomi NPP carries five science instruments and test key technologies for the JPSS missions. Suomi NPP is the first satellite mission to address the challenge of acquiring a wide range of land, ocean, and atmospheric measurements for Earth system science while simultaneously preparing to address operational requirements for weather forecasting. 3D Model created by Brian Kumanchik and Christian Lopez at NASA/JPL-Caltech. Learn more about Suomi NPP here.
Launched on June 20, 2008, the Ocean Surface Topography Mission (OSTM)/Jason-2 is an international satellite mission collects sea surface height measurements. Jason-2 high-precision ocean altimetry measures the distance between a satellite and the ocean surface to within a few centimeters. Accurate observations of variations in sea surface height-also known as ocean topography-provide scientists with information about the speed and direction of ocean cur-rents and heat stored in the ocean. This information, in turn, reveals global climate variations. 3D Model created by Kevin Lane at NASA/JPL-Caltech. Learn more about Jason-2 here.
Launched on July 2, 2014, Orbiting Carbon Observatory (OCO)-2 is dedicated to studying atmospheric carbon dioxide from Space. OCO-2 collects space-based global measurements of atmospheric CO2 with the precision, resolution, and coverage needed to characterize sources and sinks on regional scales. 3D Model created by Chris Meaney at NASA.
