Which one of the following is a spacecraft?

Result
Your answer: —  Â·  Correct: B
Explanation

Cassini is the correct answer (option 2). Cassini–Huygens was a robotic space probe/spacecraft sent to study Saturn and its moons and is a dedicated interplanetary spacecraft. Apophis is a near‑Earth asteroid, not a man‑made vehicle [1]. Spitzer is an infrared space telescope — a space‑based observatory rather than an interplanetary probe [2]. TecSAR (TechSar) refers to the TECSAR earth‑observation radar imaging satellite launched by PSLV, i.e., an orbiting satellite/platform rather than a deep‑space probe [3]. Thus, of the four choices, Cassini is the spacecraft (an interplanetary space probe) built and operated for exploration missions.
