Altair lunar lander

Target entity: Altair lunar lander
Context triple: [Constellation program, component, Altair lunar lander]

• A. SLIM lunar lander
  The SLIM lunar lander is a Japanese spacecraft designed by JAXA to demonstrate high-precision, lightweight landing technology on the Moon’s surface.
• B. Apollo Lunar Module
  The Apollo Lunar Module was the two-stage spacecraft used by NASA during the Apollo missions to land astronauts on the Moon and return them to lunar orbit.
• C. Luna spacecraft
  The Luna spacecraft were a series of Soviet robotic probes launched between the late 1950s and 1970s that achieved many lunar exploration firsts, including the first human-made object to reach the Moon and the first soft landing on its surface.
• D. Gemini spacecraft
  The Gemini spacecraft was NASA’s two-person capsule used in the mid-1960s to develop critical spaceflight techniques such as orbital rendezvous, docking, and extended missions in preparation for the Apollo Moon landings.
• E. Orion spacecraft
  The Orion spacecraft is NASA’s next-generation crewed space vehicle designed to carry astronauts beyond low Earth orbit on deep-space missions, including journeys to the Moon and eventually Mars.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
