Unlike Daedalus, which used an open-cycle
The reactor would also be used to power a laser for communications back to Earth, with a maximum power of 250 kW. For most of the journey, this would be used at a much lower power for sending data about the interstellar medium; but during the flyby, the main engine section would be discarded and the entire power capacity dedicated to communications at about 1 kilobit per second.
Longshot would have a mass of 396 tonnes (873,000 lb) at the start of the mission including 264 tonnes of
A difference in the mission architecture between Longshot and the Daedalus study is that Longshot would go into orbit about the target star, while the higher-speed Daedalus would do a one shot fly-by lasting a comparatively short time.
A travel to Alpha Centauri with a Longshot spacecraft would take about one century.
