<div dir="auto">Phase I studies are studies of how and if it could be done. Almost certainly, these will show how long the program must be kept in operation with active input, which will be a deciding factor in preventing the proposed mission from happening.<div dir="auto"><br></div><div dir="auto">The Voyagers have only lasted as long as they have because they have needed little maintenance: just some occasional software updates and coaching through certain problems. Also, no commitment was required decades in advance: if the Voyagers shut down or broke up once they reached the Kuiper belt, the primary science mission would still have been declared a success, especially if any useful data could be obtained about why that termination event happened. Maintaining an active laser feed for decades before obtaining much useful science seems beyond NASA's ability.</div><div dir="auto"><br></div><div dir="auto">(But note that "before" qualifier! A probe to study the interstellar medium, that happens to be able to reach and study Proxima Centauri if it lasts that long, is another story entirely. The primary science mission, and thus the initial commitment, would only have to last until shortly after the probe crossed our system's heliopause. Once that is accomplished, the laser can be kept on until funding dries up, something malfunctions, or - somehow - nothing goes too horribly wrong for decades and the probe reaches Proxima Centauri. However, that is not what is being proposed here.)</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jan 6, 2024, 3:30 AM BillK via extropy-chat <<a href="mailto:extropy-chat@lists.extropy.org">extropy-chat@lists.extropy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Swarms of laser-flown bots visiting a planet light years away – and<br>

Quotes:<br>
NASA is funding 13 ambitious projects that could potentially lead to<br>
space missions one day, ranging from scanning for signs of life on<br>
Mars to exploring a nearby exoplanet with thousands of swarming<br>
spacecraft.<br>
<br>
Under the NASA Innovative Advanced Concepts (NAIC) program, the US<br>
space agency supports seemingly wacky ideas put forth by industry and<br>
academia that go beyond its near-term game plans. On Friday, it<br>
announced the 2024 Phase I awardees, who will each receive up to<br>
$175,000 to flesh out their designs, and draw up roadmaps for how<br>
their proposed technologies will or could be used.<br>
