BY ALICIA CHANG AP Science Writer PASADENA — Fresh off SpaceX’s historic return from the International Space Station, company founder Elon Musk said Friday that he would like to see humans settle Mars and become a “multi-planet species.” The 40-year-old entrepre- neur reiterated his vision to graduates at the California Institute of Technology, a private university 10 miles northeast of Los Angeles known for its sci- ence and engineering programs. Musk said he hoped some of the newly minted graduates would work toward Mars colo- nization, either at SpaceX or another outfit. “You guys are the magicians of the 21st century. Don’t let any- thing hold you back,” he said. “Imagination is the limit ... go out there and create some magic.” Musk made headlines last month when SpaceX became the first private company to make a roundtrip supply run to the space station — a task that had been dominated by governments. With NASA’s space shuttle fleet retired, the space agency is outsourcing the job to private industry. SpaceX’s unmanned Dragon capsule splashed into the Pacific on May 31 after a virtual- ly flawless nine-day test flight that included docking with the multibillion-dollar orbiting out- post and delivering a load of food, clothing and equipment to the astronauts aboard. Earlier this week, Musk accompanied NASA Administrator Charles Bolden on a tour of the Dragon capsule that was plucked from the ocean and trucked to SpaceX’s factory in Texas. Save for a few scorch marks from the fiery re-entry, the bell-shaped capsule weathered its maiden journey. The audience cheered when Musk recounted the historic flight, which he called a “white knuckle event.” “It’s a huge relief. I still can’t quite believe it actually hap- pened,” he said. SpaceX aimed to launch the next supply mission in September under a contract with NASA and has predicted that astronauts could hitch rides to the space station in as little as three or four years. SpaceX planned to test the next version of the Dragon — designed to carry crews — later this year. gained the most, adding 33,900. Ohio was next with 19,600. North Carolina reported the biggest loss, shedding 16,500 jobs. It was followed by Pennsylvania, which lost nearly 10,000. “It’s good to look at the year over with the way the economy has been because for a long peri- od of time our year over figures were down,” Patterson said. Between May 2011 and 2012, Nevada County payrolls advanced by 720, representing 2.6 percent job growth over the year. Before the recession began, leisure and hospitality accounted for around 4,800 jobs, which peaked in January with 5,430 positions accounted for. “We are regaining some of those jobs lost during the reces- sion in an industry important to this region,” Patterson said. In the last year, seven indus- tries grew in Nevada County, adding 740 jobs. Those indus- tries included leisure and hospitality; trade, transportation and utilities; wholesale trade; pri- vate education and health services; professional and busi- ness services; mining, logging and construction; financial activ- ities; and information. Two industries have declined in the county over the year, together cutting back 200 jobs. Government reported the largest year-over decline by shedding 140 positions. Manufacturing also lost 60 posi- tions. To contact Staff Writer Chris Rosacker, email [email protected] or call (530) 477-4236.

James had been exhibiting combative behavior at Wayne Brown Correctional Facility and jail personnel were trying to move him from his cell to a holding cell. He started to fight them, sending several officers to the hospital, one with a broken wrist and two with groin injuries. James’ sentencing was set for July 30. In other court news On Thursday, a Penn Valley man charged with multiple counts of child molestation waived his right to a preliminary hearing of the evidence against him. Kirk Iven Goodman, 36, pleaded not guilty to an amend- ed felony complaint. Nevada County Deputy District Attorney Maria Leftwich indi- cated that she has made Goodman an offer of 26 years in state prison if he pleaded to 11 counts. He is set to return to court on July 6 for formal arraignment. To contact Staff Writer Liz Kellar, email [email protected] or call (530) 477- 4229. JAMES: Continued from A1 Photo for The Union by John Hart Cal Fire's Air Attack 23, left, takes off as Air Tanker 88 taxis on the runway. Both planes were dispatched to a fire in Butte County Friday. THE UNION STAFF The air tankers are back. On Wednesday, Cal Fire’s two air tankers — 88 and 89 — landed at the Grass Valley Air Attack Base, sporting spiffy new coats of paint. The USDA Forest Service and the California Department of Forestry built the forerunner to the air base at the Nevada County Airport in the 1950s, according to The Union’s archives. The first air tankers at the Grass Valley base were converted crop dusters, but those quickly gave way to large war- surplus bombers with larger retardant capacity. Cal Fire’s tankers these days are capable of carrying 1,200 gallons of fire retardant and have turbine-powered engines to navigate through canyons safely and efficiently. The tanker’s pilots have been kept busy in the last few years and likely will be equally so this season. In 2011, the base’s air tankers flew more than 300 missions, providing sup- port to fires up and down the state and in Nevada. In 2010, the Nevada-Yuba- Placer Unit manning the Grass Valley Air Attack base responded to 227 fires in total, 72 in Nevada County.
