AB: Well, I can"t speak for Justin, although I probably could. But my influences range from Prince to Depeche Mode. I"m a huge fan of Georgio Moroder, who did a lot of the electronic dance music in the late seventies and eighties. He did the soundtrack to Scarface, a lot of Donna Summer music . . . I really like that instrumental, dance music, but I also really like classical music: Bach, Beethoven, Bosner. Notification Area in the lower right corner of the Windows desktop can be mess quickly.

Monolith will signal the end of summer, for some of us, and what better place to throw a final "farewell summer" party than Red Rocks! With a performance roster of 40 artists and bands, and it has all summer to grow, I"m sure it will be one carousing good time. Check out the VIP ticket package, it"s got some good values and is actually fairly reasonable in price.

BEIJING -- The relay satellite for the planned Chang"e 4 lunar probe, which is expected to land on the far side of the Moon at the end of the year, has entered orbit, the China National Space Administration (CNSA) announced Thursday.

The satellite named Queqiao (Magpie Bridge) launched on May 21 and entered the Halo orbit around the second Lagrangian (L2) point of the Earth-Moon system, about 65,000 km from the Moon, at 11:06 am Thursday after a journey of more than 20 days.

"The satellite is the world"s first communication satellite operating in that orbit, and will lay the foundation for the Chang"e 4, which is expected to become the world"s first soft-landing, roving probe on the far side of the Moon," said Zhang Hongtai, president of the China Academy of Space Technology.

The concept of the Halo orbit around the Earth-Moon L2 point was first put forward by international space experts in 1950s.

While in orbit, the relay satellite can see both the Earth and the far side of the Moon. The satellite can stay in the Halo orbit for a long time due to its relatively low use of fuel, since the Earth"s and Moon"s gravity balances the orbital motion of the satellite.

"From Earth, the orbit looks like a halo of the Moon, which is where it got its name," said Zhang Lihua, project manager of the relay satellite.

He said the Halo orbit was a three-dimensional irregular curve. It is extremely difficult and complex to maintain the satellite in orbit.

"If there is a tiny disturbance, such as gravitational disturbance from other planets or the Sun, the satellite will leave orbit. The orbit period is about 14 days. According to our current plan, we will conduct orbit maintenance every seven days," Zhang said.

"Queqiao is like a little kid running wild in orbit. If there"s even the slightest negligence by our team, the satellite will be lost forever," said Guan Bin, a designer for the satellite"s control system.

"It"s a new type of orbit, we don"t have any experience. We ran a number of simulations to make sure the design is feasible and reliable," Zhang said.

In order to set up a communication link between Earth and the planned Chang"e 4 lunar probe, astrophysicists must keep the satellite stable and control its altitude, angle and speed with high precision.

Next, the team will test the communication function of the relay satellite.
