Artist's concept of AcrimSat Active Cavity Irradiance Monitor Satellite The Active Cavity Irradiance Monitor Satellite, or AcrimSat, mission is a climate change investigation that measures changes in how much of the sun's energy reaches Earth's atmosphere. 12/20/1999 Earth AcrimSat The Active Cavity Irradiance Monitor Satellite, or AcrimSat, mission is a climate change investigation that measures changes in how much of the sun's energy reaches Earth's atmosphere. This energy, called solar irradience, creates winds, heats the land and drives ocean currents, and therefore contains significant data that climatologists can use to improve predictions of climate change and global warming.

The satellite's Active Cavity Irradiance Monitor III instrument, now in its third generation, has been used since the 1980s to study solar irradiance and its impacts on global warming. Scientists, using data from the instrument, now theorize that there is a significant correlation between solar radiation and global warming.

Curiosity: The Next Mars Rover (Artist's Concept) Mars Science Laboratory Curiosity Rover The Mars Science Laboratory mission's Curiosity rover, the most technologically advanced rover ever built, landed in Mars' Gale Crater the evening of Aug. 11/26/2011 Mars MSL Gale Crater, Mars The Mars Science Laboratory mission's Curiosity rover, the most technologically advanced rover ever built, landed in Mars' Gale Crater the evening of Aug. 5 PDT (morning of Aug. 6 EDT) using a series of complicated landing maneuvers never before attempted.

Voyager Spacecraft Voyager 2 The Voyager 2 spacecraft, which has been in operation since 1977 and is the only spacecraft to have ever visited Uranus and Neptune, is currently making its way beyond the edge of the solar system, where no spacecraft or human-made object has ever ventured before. 08/20/1977 Jupiter, Saturn, Uranus, Neptune Jupiter, Saturn, Uranus, Neptune The Voyager 2 spacecraft, which has been in operation since 1977 and is the only spacecraft to have ever visited Uranus and Neptune, is currently making its way beyond the edge of the solar system, where no spacecraft or human-made object has ever ventured before. During its travels through the outer solar system, Voyager 2 visited all four gas giant planets, and also discovered and photographed many of the planets' moons.

The spacecraft's flyby of Neptune in 1989 set it on a course below the elliptic plane that will eventually take it beyond the edge of the solar system. In 1998, engineers switched off the spacecraft's nonessential instruments to conserve power. Data from at least some of the six instruments still in operation should be received until at least 2025, by which time Voyager 2 is slated to be the only human-made object outside the boundaries of the solar system.

Autonomous Sciencecraft Experiment Autonomous Sciencecraft Experiment The Autonomous Sciencecraft Experiment is an experimental technology on the Earth Observer 1 spacecraft that can autonomously make decisions about what data to collect, process that data and send it back to Earth. 06/15/2004 Earth ASE The Autonomous Sciencecraft Experiment is an experimental technology on the Earth Observer 1 spacecraft that can autonomously make decisions about what data to collect, process that data and send it back to Earth.

The Autonomous Sciencecraft Experiment was created as part of Space Technology 6, a project to develop advanced systems that would let spacecraft of the future be more autonomous. It was uplinked to the Earth Observer 1 spacecraft virtually in 2004.
