Project Lyra: Catching 1I/\textquoteleftOumuamua \textendash Mission opportunities after 2024
In October 2017, the first interstellar object within our solar system was discovered. Today designated 1I/\textquoterightOumuamua, it shows characteristics that have never before been observed in a celestial body. Due to these characteristics, an in-situ investigation of 1I would be of extraordinary scientific value. Previous studies have demonstrated that a mission to 1I/\textquoterightOumuamua is feasible using current and near-term technologies, however, with an anticipated launch date of 2020-2021. This is too soon t ...

Project Lyra: Sending a spacecraft to 1I/\textquoterightOumuamua (former A/2017 U1), the interstellar asteroid
The first definitely interstellar object 1I/\textquoterightOumuamua (previously A/2017 U1) observed in our solar system provides the opportunity to directly study material from an other star system. Can such objects be intercepted? The challenge of reaching the object within a reasonable timeframe is formidable due to its high heliocentric hyperbolic excess velocity of about 26 km/s; much faster than any vehicle yet launched. This paper presents a high-level analysis of potential near-term options for a mission to 1I/\tex ...
