The rover Curiosity and other NASA spacecraft at Mars are now in a radio blackout, as the sun is interfering with transmissions. Curiosity took this self-portrait by combining 66 exposures in February.
Communications between the Earth and Mars are on hiatus for several weeks, thanks to interference from the sun. That means NASA's orbiters and rovers that study Mars will be left to their own devices until radio signals can once again travel between the two planets.
Known as "solar conjunction," the problem arises when the orbit of planets places the sun directly between them.

This is SCIENCE FRIDAY, I'm Flora Lichtman, filling in for Ira today. You know the phrase you are what you eat? Well, new research suggests a slight modification: Your gut bacteria are what you eat. And if you eat more red meat, for example, you'll nurture populations of microbes that like to eat red meat, too, which might not seem like a bad thing except that researchers have pinpointed a compound in red meat called L-carnitine that when broken down by gut bacteria might contribute to heart disease.
This is SCIENCE FRIDAY. I'm Flora Lichtman. Later in the hour, a teenage science activist and the plight of the monarch butterfly. But first, researchers have developed a new way to fight antibiotic-resistant microbes by borrowing a trick from a longtime foe of the bacteria, the bacteria phage.
