Working towards the achievement of interstellar flight through knowledge to the stars — Starships in our lifetime.

1I/2017 U1 (‘Oumuamua) was discovered in October 2017; shortly after, it was determined to be the first object ever seen inside the solar system that had come from beyond it. But by the time its origins had been discerned, the interstellar interloper had already rounded the Sun and was speeding away at some 85,700 mph (138,000 km/h). Just an estimated 1,300 feet (400 meters) across, it faded from view of even the most powerful telescopes within weeks.

The only way to gather more data and uncover its true nature would be to send a spacecraft to study it up close. But uncertainties in ‘Oumuamua’s exact trajectory, the difficulty of detecting its ever-dimming light, and its rapid retreat make the idea of designing, building, and launching a mission in time to catch up to it seem utterly impossible.

Want to go on an unforgettable trip? Abstract Submission closing soon! Exciting news from SnT, Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg! We are thrilled to announce the 1st European Interstellar Symposium in collaboration with esteemed partners like the Interstellar Research Group, Initiative & Institute for Interstellar Studies, Breakthrough Prize Foundation, and Luxembourg Space Agency. This interdisciplinary symposium will delve into the profound questions surrounding interstellar travel, exploring topics such as human and robotic exploration, propulsion, exoplanet research, life support systems, and ethics. Join us to discuss how these insights will impact near-term applications on Earth and in space, covering technologies like optical communications, ultra-lightweight materials, and artificial intelligence. Don’t miss this opportunity to connect with a community of experts and enthusiasts, all united in a common goal. Check out the “Call for Papers” link in the comment section to secure your spot!

A big thank you to Maciej Rebisz for the images and the entire Project Lyra team for the research work!

Project Lyra develops concepts for reaching interstellar objects such as 1I / ‘Oumuamua and 2I / Borisov with a spacecraft, based on near-term technologies. But what is an interstellar object?

On October 19th 2017, the University of Hawaii’s Pan-STARRS 1 telescope on Haleakala discovered a fast-moving object near the Earth, initially named A/2017 U1. It is now designated as 1I/’Oumuamua. This object was found to be not bound to the solar system. It has a velocity at infinity of ~26 km/s and an incoming radiant (direction of motion) near the solar apex in the constellation Lyra. Due to the non-observation of a tail in the proximity of the Sun, the object does not seem to be a comet but an asteroid. More recent observations from the Palomar Observatory indicate that the object is reddish, similar to Kuiper belt objects. This is a sign of space weathering.

When will such an object visit us again? End of 2019, a second interstellar object, 2I/Borisov was discovered, which is a comet. As 1I/‘Oumuamua and 2I/Borisov are the nearest macroscopic samples of interstellar material, the scientific returns from sampling the object are hard to overstate. Detailed study of interstellar materials at interstellar distances are likely decades away, even if Breakthrough Initiatives’ Project Starshot, for example, is vigorously pursued. Hence, an interesting question is if there is a way to exploit this unique opportunity by sending a spacecraft to 1I/’Oumuamua to make observations at close range.

Asteroid starships are built by hollowing out an asteroid and creating a habitat inside plus adding a propulsion system.
