To send Red Dragon spacecraft to Mars, SpaceX is building a mega-rocket called Falcon Heavy. Based on the company’s successful Falcon 9, Falcon Heavy consists of three core rocket stages, each of which is equipped with landing legs for reusability. They would use the capsule’s thrusters to make a landing.
This artist’s illustration shows how the capsule could enter Mars’ atmosphere. SpaceX has successfully returned their capsules to Earth during space station resupply missions for NASA.
The Dragon can carry seven astronauts to and from destinations like the International Space Station (not yet a manned mission to Mars I’d guess 😄). Here’s an illustration of the Dragon Version 1 (the new version has some differences), to get the idea:

On April 21, 2014, the Hubble telescope captured what looks like a black hole in Jupiter’s Great Red Spot — but really, it’s the shadow of the Jovian moon Ganymede. (Source)
We’ve studied life on Earth extensively, but we still have no idea where it came from. Some scientists think it may have spontaneously arisen on Earth by some unknown process. Others think the ingredients for life were delivered here by comets crashing into Earth in the early days of the solar system. The latter theory just got a huge boost.

Comet Panstarrs captured in gorgeous time-lapse above the skies of Boulder, CO by Patrick Cullis. Lovely stuff.
Comets are mysterious frozen chunks of stellar and planetary debris, these dirty snowballs that wander in darkness until their tails are blown bright and wide by solar winds. Some follow paths so random and eccentric that they may pass a star only once, or perhaps not at all, instead floating through interstellar space, never to be known. But for those fleeting moments, like Panstarrs’ current passage, they are like icy candles lit for our enjoyment by the breath of the sun.
A song of ice and fire, indeed.
