Mars has apparently claimed another robotic explorer. Europe's Schiaparelli Mars lander is most likely dead on arrival, after something went wrong during its parachute flight and its hover-rockets didn't ignite for long enough. European Space Agency engineers are still trying to piece together exactly what went wrong at some point during the lander's descent yesterday.
Mars might have claimed another robot. After a nailbiting descent, we still don't know whether Europe's Schiaparelli Mars lander is safe on the Red Planet. The Mars Express and Mars Reconnaissance Orbiter should be able to tell us, but it will be another hour or so before they can pass overhead and beam data back to Earth.
Today on Mars, a 13-year-old American robot will look up from its crater to photograph the arrival of a new European companion. It's a solar system first: No robot on the the surface of another planet has ever been there to greet a new space traveler.
Planetary scientists sometimes joke that we know more about Mars than we do about the moon. NASA first landed a spacecraft on the surface of the fourth planet during the U.S. Bicentennial, five years before the first space shuttle ever lifted off.
Like painted kites, those days and nights went flyin' by The world was new, beneath a blue umbrella sky Then softer than a piper man, one day it called to you And I lost you, I lost you to the summer wind...
Single-exoplanet systems may be the fault of their stars. Exoplanets are abundant in the galaxy, but the systems they belong to seem to come in two distinct configurations. Some stars have multiple planets orbiting in the same plane, much like the solar system. But some appear to have only one world crossing their face.
In August, we learned that the nearest star to our solar system is likely to have a rocky, Earth-sized planet orbiting it - and now the star, too, turns out to be more like the sun than we thought. Proxima Centauri has been found to experience a seven-year activity cycle, similar to the sun's 11-year cycle.
HOW do you iron out the folds in a universe? Our most precise map of the big bang's afterglow - the cosmic microwave background (CMB) - is flawed, distorted by the gravity of giant galaxies warping the fabric of space-time.
Brace for impact. A new count of the moon's craters has turned up 33 per cent more than predicted. Bombardment by small meteors is continually churning up the surface of the moon, and the dust-up could pose hazards to future lunar settlements. Small meteors regularly impact the moon and Earth.
Astronomers have never seen anything like it: two stars, each swaddled in planet-forming discs - and then a third, larger disc around the entire lot. Named IRS 43, the system is 400 light years away from Earth. The cosmos is chock-full of stars surrounded by planets and planet-forming discs.
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
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".
