Deep Space One Ion Engine Restarted.
The B~Hive Cafe/Eyes on Space is a light-hearted look at the space industry. Celebrating a 3rd year online, they've come out with a special 4th of July Issue. Check it out:

NASA SUCCESSFULLY TESTS light SAIL TECHNOLOGY
NASA scientists have successfully propelled prototype light sails using beamed microwaves and laser energy. The sails in the microwave experiment were actually propelled into the air, while the laser experiment pushed the sails horizontally. These prototypes will help NASA understand the science involved in light sails, and will help them develop large enough sails to carry probes in the solar system.
HUBBLE IMAGES COSMIC SEARCHLIGHT
New photos released from the Hubble Space Telescope show a jet of electrons and subatomic particles streaming out of the centre of Galaxy M87 at near light speed. The jet is created by a massive black hole, 2 billion times the mass of the Sun, which lives at the heart of M87. Fortunately, M87 and its massive black hole are a healthy 50 million light years away from us.
SUCCESSFUL Proton LAUNCH CLEARS THE WAY FOR ZVEZDA
A Proton rocket launched from the Baikonur Cosmodrome in Kazakhstan on Tuesday evening, carrying a Geyser military communications satellite. The launch is significant, because it's the second test of the upgraded second- and third-stage boosters - the same which will carry the Zvezda service module to orbit on July 12th. The engine upgrades were made after faulty engine welds caused two Proton launch failures last year.
DEEP SPACE ONE ION ENGINE RESTARTED
NASA spacecraft Deep Space One has been in safe mode for the past seven months after its star tracker malfunctioned - an instrument that allows the probe to determine its orientation within the solar system. Engineers wrote new software that would turn the spacecraft's scientific camera into a star tracker. The new software appears to be working properly, and the ion engine has been successfully restarted, putting the probe back on course for its 2001 rendezvous with Comet Borrelly.
