TL;DR: The Lander Philae, part of the ESA Rosetta mission successfully landing on comet 67P/Churyumov-Gerasimenko on November 12th, 2014, performed a First Scientific Sequence (FSS) based on the energy stored in its on board batteries as mentioned in this paper.

TL;DR: In this article, the authors proposed a mission called GETEMME (Gravity, Einstein's Theory, and Exploration of the Martian Moons' Environment), a mission which is being proposed in ESA's Cosmic Vision program, shall be launched for Mars on a Soyuz Fregat.

TL;DR: The Triple F ( Fresh From the Fridge) mission as mentioned in this paper was proposed to extract three sample cores of the upper 50 cm from three locations on a cometary nucleus and return them cooled to Earth for analysis in the laboratory.

TL;DR: The MASCOT lander was deployed successfully on October 3, 2018 by the Hayabusa2 spacecraft onto the C-type near-Earth asteroid (162173) Ryugu.

TL;DR: In this article, the authors introduce several mission concepts that might address the open questions about the feasibility of a sample return mission to the cometary nucleus and its immediate environment, and discuss the suggested main outstanding scientific goals.
