Delta 3 Missed its Target But Within Margin of Error.

Further Evidence of Europa's Oceans
Delta 3 Missed its Target But Within Margin of Error
Powerful, But Tiny Black Hole
FURTHER EVIDENCE OF EUROPA'S OCEANS
Data gathered by the Galileo spacecraft support the theory that Jupiter's Moon Europa has a liquid ocean beneath its icy surface. The data came from magnetic readings taken on the moon's internal magnetic field - it strongly indicates the presence of a salty ocean. NASA has future missions in the planning stages which will help determine, once and for all, if Europa does have a liquid surface.
DELTA 3 MISSED ITS TARGET BUT WITHIN MARGIN OF ERROR
After hailing yesterday's Delta 3 launch as a "complete success", Boeing admitted that the rocket with its dummy cargo ended up a thousand kilometres off its planned orbit. Although it ended up off-course, Boeing considers the trajectory to be within an acceptable margin of error. The Delta 3 carried a simulated satellite cargo to demonstrate to potential clients that any problems with the booster have been repaired - after its previous two launches ended in failure. Boeing has 18 more Delta 3 launches planned.
POWERFUL, BUT TINY BLACK HOLE
Astronomers have found a relatively tiny "supermassive" black hole pulling in as much matter and radiating as many X-rays as much larger holes. Located at the core of Galaxy NGC 4395, this black hole is part of a new classification of mid-mass black holes. It's suspected that this hole contains the mass of 10,000 to 100,000 Suns.
