Minerals point to martian oceans
The discovery of certain soil chemicals by NASA's rovers suggests an ocean of water was once quite abundant on Mars. But the same chemicals also indicate that life was not widespread on the planet at that time. Some researchers argue that the broad, flat area in Mars's northern hemisphere is the remains of a once massive ocean. The uniform phosphorus-to-sulphur ratio detected by both Mars rovers is the first chemical evidence that such a large body of water could have existed. Sadly, the large amounts of phosphates point to a rather small biosphere for Mars because, on Earth, phosphates are quickly used up by biological processes.

People have spoken of using orbital mirrors to warm the surface of Mars for a long time. Well, Rigel Woida, an engineering student at Arizona State University in Tucson, US, has recieved $9000 from the NASA institute for Advanced Concepts (NIAC) in Atlanta, Georgia, to explore the possibility of using mirrors to "terraform" a small portion of the martian surface so astronauts don't need heavily insulated materials to preform their day-to-day functions. The mirror would focus sunlight onto a 1-kilometre-wide patch of the planet's surface. This focused sunlight would raise the temperature in this patch to a balmy 20° Celsius (68° Fahrenheit) from Mars's typical surface temperature of between -140° C and -60° C (-220° and -76° F).

1000 Sols of Spirit
The most detailed panorama ever released by the MER mission comes on Sol 1000 of Spirit's life on Mars. This comes after several months spent with Spirit perched facing north to maximize energy from the solar panels. Congratulations to the MER team!

dreammaker has submitted a short review of his experience at the XCup. You can read it here.
From Announcing the Wirefly X Prize Cup page, describing some of the:
The Vertical Rocket Challenge is another lunar-landing-technology-focused competition
The primary differences between the Vertical Lander Challenge and the Lunar Lander Challenge are the minimum time of flight (90 vs. 180 sec.), the surface terrain at the landing sites (flat vs. rocky) and the degree of difficulty presented for precision landing.
During the Space Elevator Games, more than 20 teams will face the challenge to use light to power a vehicle along a tether -- this year up about 50 meters, but eventually hundreds and thousands of miles.
