Just over a year ago,the venerable old Voyager I spacecraft left the solar system,although not the sun's influence entirely,and entered interstellar space,the space between the stars,NASA scientists reported this week.It is now in the transition zone just outside the solar bubble,and in the ionised gas between the stars.Some solar disturbance still obtains in this transition zone.
We believe this is mankind's histric leap into interstellar space,said Ed Stone,Voyager Project Scientist at Caltech,Pasadena.Voyager had entered the heliosphere,or solar bubble of charged particles which defines the edge of the solar system,in 2004.It first entered interstellar space on 12 August,2013,when an abrupt change in the density of energetic particles was first detected by Voyager I.
Suzanne Dodd,Voyager Project Manager at NASA's Jet Propulsion Laboratory,Pasadena,said we expect the fields and particles science instruments on Voyager will continue to send back data through at least 2020.We can't wait to see what the Voyager instruments show us next about deep space.
Voyager I's twin,Voyager II,was actually launched a few weeks ahead of Voyager I in 1977.Both spacecraft flew by Jupiter and Saturn,but Voyager II veered off to fly by Uranus and Neptune as well.Scientists talk to or receive data from both spacecraft almost every day.It takes the weak 23 watt signal of Voyager I about 17 hours to reach earth.As of its February 21,2013 radio telescope image,Voyager I was 11.5 billion miles/18.5 billion kilometers from earth.It is now about 19 billion miles away.

Santa Anas Blast SoCal;McIlroy and Quiros Lead
The San Gabriel Valley was rocked by hurricane force Santa Ana winds this week in a rare event the likes of which are seen only once in 5-10 years.The tremendous gusts decimated the urban forests of Southern California as communities lost hundreds of treasured trees,losing power and even water in the process.Pasadena was particularly hard hit,with some 450 street trees being toppled by the winds.Homes were damaged in these lands along the San Gabriel Mountains,where gusts of up to 80 mph were recorded.
The fire risk was described as explosive by a weather service official.The Santa Anas are known for the catastrophic wildland fires they often contribute to in the region.
Rumors of European progress and positive manufacturing and employment trends protected the market this week.All major averages posted gains north of 7%.For the week,the S&P 500 rose 7.39.On the year,the S&P is still down 1.06,however.
The Race To Dubai,The European Tour,made its next to last stop at the Hong Kong Golf Club.After two rounds of the UBS Hong Kong Open,Alvaro Quiros of Spain and Northern Ireland's Rory McIlroy topped the leader board.Luke Donald of England led the series going into this weekend,followed by German Martin Kaymer and McIlroy in second and third place,respectively.
Next week will be back-loaded by an important Friday summit in Brussels on changes to the EU treaty for fiscal discipline.Other influential events will include the Institute for Supply Management's service sector report on Monday and a consumer sentiment reading also on Friday.The S&P futures were basically flat at -0.10 Friday evening,while bond index futures rose.
