Spacewalkers complete 4 years of power upgrades for station

first_imgCAPE CANAVERAL, Fla. (AP) — A four-year effort to modernize the International Space Station’s power grid is finally complete. A pair of NASA astronauts installed the last battery during a spacewalk Monday, and the unit checked out well. It was the second spacewalk in five days for Mike Hopkins and Victor Glover. Over the weekend, flight controllers in Houston used the station’s big robot arm to replace the last batch of old batteries with a new, more powerful one. Hopkins and Glover quickly put the finishing touches on this newest lithium-ion battery. Their work completes a series of spacewalks that began in 2017.last_img read more

Women’s soccer preps for home opener

first_imgMcAlister Field is a welcome venue this weekend for the road-weary USC women’s soccer team.After successful consecutive road trips, the Women of Troy will host the Trojan Invitational, which invites three teams—No. 25 Auburn (4-1), Northern Arizona (0-2-2) and Cal State Fullerton (2-2)—to Los Angeles. Continuing their string of nonconference play, the Women of Troy will butt heads with another nationally ranked team, Auburn, Friday at 3:30 p.m. After a one-day respite, the tournament will conclude with a 1:30 p.m. matchup against Northern Arizona (0-2-2) on Sunday.Standing tall · Junior midfielder Carly Butcher and the Women of Troy will return home this weekend for the first time in three weeks, as USC hosts the Trojan Invitational. – Daily Trojan file photo Despite the recent encouraging road trips, a theme evident in this week’s practices was the need to shoot purposefully and aim for corners. Offensively challenged so far in the early going, the Women of Troy have yet to score more than one goal in any game, and imprecise shooting has foiled many of their scoring chances.To help the team visualize its shooting targets, coach Ali Khosroshahin stacked three hula hoops vertically on each side of the net during practice, ensuring that all four corners of the net were highlighted for oncoming attackers.“We need to keep taking care of the ball,” Khosroshahin said. “We were better than we were all year [in that regard] this last weekend. However, the final third part of the field still needs work.”The fact that the Women of Troy are finally approaching full health bodes well for the rest of the season, especially since they have weathered injuries to key contributors, most notably leading scorer Ashli Sandoval. Unfortunately, as the team continues to welcome back more players from the injured reserve, it lost junior defender Chelsea Buehning for the season to an ACL injury, for which she underwent surgery this past Wednesday.Although the Women of Troy have yet to earn a top-25 ranking since the first weekend of the season, they are not overly concerned. Instead, they are using this opening deluge of nonconference games to prepare for a challenging conference schedule — a point at which one game can define a season.“I think it’s good to play all of these games before we start our Pac-10 schedule because it gives us time to work on things,” Butcher said. “We want to get that No. 1 seed in the Pac-10 [postseason] tournament.”Khosroshahin was more non-committal in his response—adhering to his philosophy of just focusing on his team.“That’s just the way it’s done,” he said.Combined with their usually stalwart defensive effort, the Women of Troy plan to put up some crooked numbers this weekend on the McAlister Field scoreboard. If their dormant offense erupts, they will begin to draw the attention of more national poll voters and even the attention of those Pac-10 teams that are discounting the unranked Women of Troy as a serious threat.last_img read more
