Today, NASA's venerable Cassini craft will fall into the clouds of Saturn, sending back scientific data even as it descends to its own demise. Then, it will go quiet, and the craft's incredible 20-year odyssey will come to an epic end. Cassini's mission has set an incredible benchmark to which future NASA missions can aspire, but its accomplishments will be hard to top.
At 4:55 a.m. PDT, the Cassini probe went quiet. An hour-and-a-half before, it hit the upper cloud layers and got ripped and burned apart by the atmosphere at 9.9 degrees north. The estimated time was 3:30 a.m. PDT, but Saturn is so far away that even at the speed of light, that signal took quite some time to reach Earth. The final whispers of the craft were heard by the Canberra dish of the Deep Space Network in Australia.
For now, the Jupiter probe Juno is our lone craft in the “second zone” of our solar system, which contains the gas and ice giant planets and their approximately 170 moons. Juno is expected to meet a controlled destruction into Jupiter next year. There are rumblings of missions to Uranus and Neptune, but those are decades away. The Voyager crafts, weakly functioning but still alive, are speeding out of our solar system as fast as they can go, tasting the constituent particles of interstellar space.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Obama AND Romney or Obama + Romney.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used.) For example, search for democrat OR republican to find results that refer to
Democrats and/or Republicans.
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
