As promised we are dedicating today’s post to the New Horizons spacecraft. The unmanned robot probe (which is the size of an unwieldy motorcycle) flew past Pluto at 7:49 a.m. EST, traveling at nearly 50,000 kilometers per hour (31,000 mph). At its nearest approach, the craft was only 1200 kilometers (7500 miles) above Pluto’s surface—closer to Pluto than Brooklyn is to Botswana.
Because of the shape and size of the solar system, the telemetry of the mission, and the niceties of radio-communication, NASA did not receive the information dump from the spacecraft until 00:53 GMT Wednesday which is uh…approximately right now! So I haven’t had any time to groom the Pluto data! Today’s post is thus more of a laurel. But the information does exist—the craft survived and completed its mission. We have a trove of knowledge about Pluto to help scientists understand the nature of the solar system—or to conceive of what kinds of new questions to ask about other planetary systems. Maybe I’ll be desperately writing another post tomorrow if scientists unexpectedly find canals on Pluto or discover that Nyx is really a giant egg or something, but most likely this data will take a long time to process and understand. Such is the nature of science (and most worthwhile pursuits). So what is the purpose of this post?
I have never been unduly upset about the designation “dwarf planet” for things like Pluto, Ceres, Eris, and Haumea. However I did grow up with “My very educated mother just served us nine pizzas” (a much snappier mnemonic than “My very educated mother just served us nothing”), and the idea of Pluto as the final planet still holds undeserved weight in my subconscious. I have thus been taking NASA’s self-congratulatory PR announcements seriously when they say “we complete the initial reconnaissance of the planets.” That sounds right to me. Humankind has gathered a great deal of information about the solar system. Now it is time to brainstorm some new objectives before the fickle public loses its interest and wanders off.
There is a national consensus that we should be spending all of our money on expensive cell phones and vastly overpriced (yet disturbingly ineffectual) medical care. The space age is reckoned to be over—and space should now be left to the likes of Elon Musk and other James Bond villain-ish mega billionaires. I think this is wrong, wrong, wrong, wrong, ever so wrong. Now that we have some ideas about what is out there we should use our hard-won knowledge to do tremendous things! My favorite next step is an atmospheric mission to Venus. Let’s send some cool space blimps to sit in the high atmosphere of our sister planet and maybe launch some weird little drones and smaller balloons into the atmosphere. We could find out whether a floating colony is even feasible. Plus it would be like the Montgolfier brothers and the Wright brothers all over—on another world!
The idea of a human mission to Mars and a submarine mission to Europa also have great merit—but I see them as more difficult and with less practical purpose. What are your favorite ideas about what to do next? This seems like a good moment to at least talk about the direction we are headed, even as we sip champagne and dance joyously about what we have done.
