Solar sailcraft are due to their high ΔV-capability especially capable to perform multiple rendezvous and sample return missions to near-Earth objects. Even with moderate-performance solar sails of the first generation, challenging scientific missions are feasible at relatively low cost. Within this paper, it will be shown that a 300 kg-spacecraft (including a lander and a sample return capsule), propelled by a (70 m)<sup>2</sup> solar sail with an additional mass of about 110 kg (specific weight 23 g/m<sup>2</sup>), is capable to return a sample from a near-Earth asteroid to Earth within 10 years from launch. In another scenario, a solar sail of the same size and weight is able to propel a 75 kg-spacecraft to rendezvous three near-Earth asteroids subsequently within 7.6 years from launch (with about 200 days of operations at each asteroid). A larger solar sail of about (140 m)<sup>2</sup> would even be capable to transport a spacecraft that returns samples from the three near-Earth asteroids to Earth within about 10 years from launch.
