  • A. Landsat satellites
    Landsat satellites are a series of Earth-observing spacecraft that provide long-term, continuous multispectral imagery used worldwide for environmental monitoring, land-use mapping, and resource management.
  • B. Deep Space Climate Observatory
    The Deep Space Climate Observatory (DSCOVR) is a NOAA and NASA satellite positioned at the Sun–Earth L1 Lagrange point that continuously monitors solar wind conditions and provides real-time space weather and Earth observation data.
  • C. Magellan spacecraft
    The Magellan spacecraft was a NASA robotic probe launched in 1989 that used radar mapping to produce the first detailed global images of the surface of Venus.
  • D. ALOS Earth observation satellites
    ALOS Earth observation satellites are Japanese remote-sensing spacecraft designed to collect high-resolution imagery and data for mapping, disaster monitoring, and environmental observation.
  • E. Vanguard 1 satellite
    Vanguard 1 satellite is an early American artificial Earth satellite launched in 1958 that became the fourth human-made object in space and the oldest still in orbit, used primarily for geophysical and atmospheric research.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
