Project Starshot: Visiting the Nearest Star Within Our Lifetime
Project Starshot: Visiting the Nearest Star Within Our Lifetime
Ζωντανή μετάδοση στις 1 Δεκ 2016
The
nearest star to the Sun, Proxima, was discovered this year to host an
Earth mass planet in its habitable zone. Proxima is only 4.24 light
years away. Can a camera fly by this planet to find out whether there is
life on it? Starshot is a new project aimed to develop the technology
that will enable to launch a spacecraft at a fifth of the speed of
light, so that it will reach Proxima within our generation. The concept
is based on a high power (100GW scale) laser beam pushing a lightweight
(gram scale) sail, attached to a chip containing a miniaturized camera,
communication and navigation devices. The feasibility study phase of the
project had just started at a funding level of $100M for the next 5-10
years, with CfA participation.
