CU :$20 million instrument package set for integration on Mars spacecraft
Nov 19th
A $20 million remote sensing instrument package built by the University of Colorado Boulder, which is leading a 2013 NASA mission to understand how Mars might have lost its atmosphere, has been delivered to Lockheed Martin in Littleton, Colo., for spacecraft integration.
The remote sensing package designed and built by CU-Boulder’s Laboratory for Atmospheric and Space Physics consists of the Imaging UltraViolet Spectrograph, or IUVS, as well as its electronic control box, the Remote Sensing Data Processing Unit, or RSDPU, both under contract to NASA Goddard Spaceflight Center in Greenbelt, Md.
Known as the Mars Atmosphere and Volatile EvolutioN, or MAVEN, the $670 million NASA mission set for launch in November 2013 is being led by CU-Boulder Professor Bruce Jakosky. The mission is designed to explore and understand how the loss of atmospheric gas has changed the climate of Mars over the eons, said Jakosky, also associate director of LASP.
“With the delivery of this package, we are shifting from assembling the basic spacecraft to focusing on getting the science instruments onto the spacecraft,” said Jakosky, also a professor in the geological sciences department. “This is a major step toward getting us to launch and then getting the science return from the mission.”
According to David Mitchell, MAVEN project manager from NASA Goddard, “The remote sensing package team built a system that meets all technical requirements and delivered it on schedule and on budget. I look forward to the instrument’s next level of integration onto the spacecraft and ultimately the science it will provide.”
The IUVS collects UV light and spreads it out on a spectra that is recorded using imaging detectors, said Mitchell. As the “brains” of the instrument package, RSDPU receives and executes commands telling the IUVS when and where to point.
“As the ‘eyes’ of the remote sensing package, the IUVS allows us to study Mars and its atmosphere at a distance by looking at the light it emits,” said Nick Schneider, a LASP research associate and lead IUVS scientist for MAVEN. “Ultraviolet light is especially diagnostic of the state of the atmosphere, so our instrument provides the global context of the whole atmosphere for the local measurements made by the rest of the payload,” said Schneider, also a faculty member in the APS department.
The CU-Boulder remote sensing package will be turned on for its initial checkout 21 days after launch, said NASA officials. Later, in the “cruise phase” of the mission from Earth to Mars, the package will be powered on twice more for “state-of-health checks” and in-flight calibration.
MAVEN will be the first mission devoted to understanding the Martian atmosphere, with a goal of determining the history of the loss of atmospheric gases to space through time, providing answers about Mars climate evolution. By measuring the current rate of gas escaping to space and gathering enough information about the relevant processes, scientists should be able to infer how the planet’s atmosphere evolved over time.
The MAVEN spacecraft will carry two other instrument suites. The Particles and Fields Package, built by the University of California Berkeley Space Science Laboratory with support from LASP and NASA Goddard, contains six instruments that will characterize the solar wind and the ionosphere of the planet. The Neutral Gas and Ion Mass Spectrometer, provided by NASA Goddard, will measure the composition and isotopes of neutral ions.
“Three of the big milestones in an instrument builder’s life are the day you get selected to fly on a mission, the day you deliver the instrument to the spacecraft to get ready for launch, and the day that it gets where it’s going and data starts flowing back from space,” said Mark Lankton, the remote sensing package program manager at LASP. “The remote sensing team is really happy to have gotten to the second milestone, and we can hardly wait to reach the third.”
CU-Boulder also will provide science operations and lead the education and public outreach efforts. NASA Goddard manages the project and is building two of the science instruments for the mission. Lockheed Martin is building the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., provides navigation support, the Deep Space Network, the Electra telecommunications relay hardware and operations.
“Our CU-Boulder IUVS instrument will be the most capable ultraviolet spectrometer ever sent to another planet,” said LASP instrument scientist William McClintock. “Data from the IUVS will help planetary scientists rewrite the textbooks about the upper atmosphere of Mars, and we are fortunate to have a top-flight engineering team here at LASP that allowed us to design and develop such a sophisticated instrument.”
Clues on the Martian surface, including features resembling dry lakes and riverbeds as well as minerals that form only in the presence of water, suggest that Mars once had a denser atmosphere that supported liquid water on the surface, Jakosky said. CU-Boulder’s participation in Mars exploration missions goes back to 1969 when NASA’s Mariner 6 and Mariner 7 missions launched.
MAVEN is slated to slide into orbit around Mars in September 2014, and, after a one-month checkout period, will make measurements from orbit for one Earth year. The MAVEN science team includes three LASP scientists from CU-Boulder heading instrument teams — Schneider, Frank Eparvier and Robert Ergun — as well as a large supporting team of scientists, engineers and mission operations specialists.
MAVEN also will include participation by a number of CU-Boulder graduate and undergraduate students in the coming years. Currently there are more than 100 undergraduate and graduate students working on research projects at LASP, which provides hands-on training for future careers as engineers and scientists, said Jakosky.
Brooks: Young Buffs Bring Home Charleston Championship
Nov 19th
By B.G. Brooks, CUBuffs.com Contributing Editor
CHARLESTON, S.C. – If some of the Colorado Buffaloes are still wet behind the ears, they are also gritty beyond their years. The young Buffs capped a rugged three-game run with an 81-74 win against Murray State here Sunday night to win the Charleston Classic, giving CU its first in-season tournament title since the 2002-03 team won the Pepsi Classic in Charlotte, N.C.
It was a good week for CU in the dank, drizzly Old South for a number of reasons, starting with:
Askia Booker was high scorer for the Buffs
- Sophomore Askia Booker compiled 58 points in three games – a 19.3 average and a career-high 23 in the championship game – and was named the tournament’s MVP. No other Buffs were chosen to the all-tournament team, more of a testament to the strong and individually talented field than a CU slight.
- After successfully defending three premier point guards – Dayton’s Kevin Dillard, Baylor’s Pierre Jackson, Murray State’s Isaiah Canaan – CU sophomore Spencer Dinwiddie might return to Boulder with a lock-down rep. He was into them like a virus. “He did a great job . . . he took on the responsibility of their guards,” Booker said. “I give all the praise to him. He took all the pressure off of me.” But Dinwiddie also found time to score: He finished the championship game with 13 points.
- Freshmen post Josh Scott and Xavier Johnson and freshmen guards Eli Stalzer and Xavier Talton did what was asked of them in their roles. Scott scored nine of his 13 points in Sunday night’s decisive second half, when CU wanted to take the battle to Murray State in the low block. He also snagged six rebounds. Stalzer and Talton spelled Booker and Dinwiddie. Johnson, said coach Tad Boyle, let a couple of fouls diminish his aggression.
- Junior Andre Roberson scored for the first time in double figures (16) this season and finished one rebound short (nine) of his first double-double this year. Even though it was waved off because of an alleged charge, he had a thunderous dunk in the second half that Boyle called an energy boost for his team.
- The Buffs discovered that, yes, they can shoot free throws when a game is on the line. After clanking and clunking them in the first two games – including missing 14 of 18 against Baylor – they sank 27 of 36 Sunday night. In the game’s final 7:58, CU hit 18 of 20. Dinwiddie stuck 11 of 12.
- And Boyle went to 4-0 for the first time in his three seasons as CU’s head coach and now must find room for the Charleston Classic trophy along the Pac-12 Conference tournament hardware his team claimed last March. Boyle also got a congratulatory handshake Sunday night from Bill Murray – no relation to Murray State – and promised he “didn’t throw any Caddy Shack lines at him. He probably gets that all the time. It was good to meet him and he said he liked our team.”
What wasn’t to like about the Buffs in their three games here, particularly Sunday night? CU advanced to the championship game with a 67-57 win against Dayton, then by edging No. 16 Baylor 60-58. Murray State started four seniors and a junior from a team that went 32-2 last season.
Booker called winning the tournament “a confidence booster for everybody. We played three good teams . . . we can play with anybody. There’s nobody in the country we can’t compete against and win. We play team ball and it comes down to defense and rebounding at the end of the day. Coach tells that to us every day.”
Shooting 45.2 percent from the field, the Racers are the only team this season the Buffs haven’t held below their goal of 40 percent. But CU outrebounded Murray State 35-30 and won the board battle in two of the three games here.
Boyle was particularly proud of his team’s ball screen defense against the high-profile three point guard the Buffs faced. “It was a team victory, offensively and defensively, and I couldn’t be more proud of our team and players,” he said.
But Boyle, of course, believes there can/will be improvement through November. The Buffs don’t play during Thanksgiving week, returning to the Coors Events Center on Sunday, Nov. 25 to face Air Force (6 p.m., Pac-12 Network). Boyle is looking at this week as quality practice time.
CU led 33-31 at halftime Sunday night, rallying from a pair of six-point deficits. Boyle had cautioned his team about Canaan’s long-range shooting, and it didn’t take long for the CU coach’s words to ring true. The 6-1 senior took six of Murray State’s 14 first-half three-point attempts and hit half of them – the last two appearing a couple of steps beyond NBA range.
Dinwiddie rolled his eyes in disbelief. “People just don’t do that,” he said. “Not that people can’t, but it’s just the coach never says please go and shoot a 35-footer. So I wasn’t expecting it. He’s a great player, very difficult to guard.”
Canaan finished with a team-best 21 points, but didn’t hit a trey in the second half.
The Buffs hurt themselves with a season-worst 11 first-half turnovers, exceeding their first two game totals here by two. But they continued to compensate with defense and rebounding, holding the Racers to 35.7 percent from the field (10-of-28) and outboarding them 19-14. And in the second half, CU cut its turnovers to six.
The Buffs opened the second half with a 6-2 run, getting baskets from Johnson, Sabatino Chen and Roberson to go up 39-33, with that six-point advantage CU’s largest of the game. But Boyle also had warned his players to keep 6-7 Ed Daniel off the glass, and the next two Racers possessions showed why. A put-back stuff cut the Buffs lead to 39-35 and a layup on the next trip made it 39-37.
Then Murray State’s three-point shooters switched on. Stacy Wilson hit one, giving the Racers a 40-39 lead, Dinwiddie banked in a trey to push the Buffs back in front 42-40, then Dexter Fields answered with a triple to give Murray State a 43-42 edge.
A back-and-forth half appeared to be underway until CU unleashed a 6-0 run highlighted by back-to-back stuffs by Scott on a baseline move and Booker on a breakaway. That surge opened a 48-45 Buffs lead with just under 12 minutes remaining.
Seconds later, after Murray State coach Steve Prohm was whistled for a technical, a pair of Dinwiddie free throws sent CU’s advantage to 50-45. Things were heating up. Roberson picked up his third foul when he was called for a charge on his he-man jam over Daniel.
At the 10 minute mark, a sweet baseline move by Scott resulted in a layup and capped a 10-0 run that had opened a 52-45 CU lead. Murray State was far from done, answering with a 7-0 run capped by another trey by Fields to tie the score at 52-52 with 8 minutes left.
The next 3 minutes were all Buffs; they went on an 11-1 run highlighted by free throws from Scott, Adams and Chen; another Scott field goal from the low post and a Booker trey from the left wing.
With 5:02 to play, CU led 63-53. Murray State closed to 63-58 on a conventional three-point play by Daniel – and Roberson also picked up his fourth foul on that play.
At 1:51, another trey by Fields brought the Racers to 68-65 and prompted a timeout by Prohm. CU answered with a free throw line jumper by Booker, two free throws by Chen. Wilson hit a long trey with a minute remaining (72-68), but Scott negated that with a layup and a free throw to restore CU’s seven-point lead (75-68).
Roberson fouled out with 13.4 seconds left, sending Daniel to the free throw line for a potential three-point play. But he missed and the Buffs’ lead was 77-72. Dinwiddie hit another four free throws in the final 10 seconds and this one was done.
Winning the tournament, he said, “means a lot; it gets our players used to winning. We don’t want our team ever to get used to losing. It kind of builds that pride and sense of urgency, that will to say we don’t lose. Period. That’s just what it is.”
Should the Buffs be included in this week’s Top 25? Booker said it “doesn’t matter,” Dinwiddie said, “Yes . . . keep it conservative and go like (No.) 17.”
The Buffs did their parts in Charleston, the polls are best left to others. It’s very early in a long season, but you can’t help but feel a buzz from how it’s started.

Colorado Women’s B-ball Team’s Front Court Dominates In 78-55 Win At UMKC
Nov 18th
Arielle Roberson scored 23 in her second CU game
KANSAS CITY, Mo. – One freshman forward started, one finished. No matter the order of appearance the recipe provided a winning combination for Colorado.
Arielle Roberson and Jamee Swan combined for 37 points on 71 percent shooting as Colorado defeated Missouri-Kansas City, 78-55, Sunday afternoon at the Swinney Recreation Center on the UMKC campus.
Colorado improved to 2-0, claiming its 15th straight win over nonconference regular season opponents dating back to 2010. UMKC drops to 2-2.
Swan, making her first career start, scored 10 of her 14 points in the first half to give the Buffaloes a good start. After picking up her third foul early in the second half, Roberson stepped in scoring 19 of her game-high 23 points in the last 20 minutes.
Roberson was 9-of-12 from the field, hit all five free throw attempts and grabbed six rebounds. Swan was 6-of-9 from the floor had three rebounds and an assist.
The freshman front court duo helped the Buffaloes dominate in the paint, outscoring the Kangaroos 42-14 inside.
“I give all the credit to my teammates,” Roberson said. “We knew coming out of the locker room we needed to push the ball and run more, really turn it up in the second half.
“I knew I had to bring defensive intensity and that led to offensive intensity for everybody.”
Roberson and Swan were the beneficiaries of a Colorado offense that picked apart the UMKC zone; putting on a passing clinic from all five positions. The Buffaloes had 17 assists on 32 made shots and overall shot 47 percent for the game.
That offense ran through forward Jen Reese and center Rachel Hargis. Playing in the high post, Reese and Hargis continually made the right pass, either finding Roberson and Swan on the low block or dishing out to continue through the guards.
Officially the two combined for six assists, but their initial reads led to plenty of good looks for the Buffaloes all afternoon.
Reese also had 10 points on 5-of-8 shooting with eight rebounds. Hargis made 3-of-4 field goals finishing with eight points.
“Our four post players, Arielle, Rachel, Jamee and Jen really dominated the game,” CU head coach Linda Lappe said. “They really understood what we were trying to do in our zone offense. I thought they did a fantastic job of being a presence on the inside.”
After Lauren Dudding put UMKC up with a 3-pointer on its initial possession, Colorado scored nine straight including two buckets from Swan.
UMKC briefly retook the lead with a 7-0 run of its own for a 10-9 advantage six minutes in. Roberson and Swan had back-to-back scores to put CU up for good.
The Kangaroos kept CU close early. Eilise O’Connor scored eight of her 10 points in the first half as UMKC pulled to within two at 18-16, but then the Buffaloes went to work. Colorado scored on five of its next six possessions during an 11-0 run to take a 29-16 lead. Hargis had a three point play and Roberson and Reese each scored on put-backs off CU misses.
“The start was important, we really needed that to kick-start our momentum,” Swan said. “Starting off great helps us finish great.”
Offensive rebounding was key for the Buffaloes, grabbing 19 which led to 22 second chance points. Overall Colorado enjoyed a 44-29 advantage on the boards.
“Offensive rebounding was a huge improvement (from the season opener),” Lappe said. “We crashed the glass against the zone and got a lot of put-backs. The effort on the offensive glass was fantastic.
Colorado led by nine at the half (36-27). UMKC’s Kim Nezianya quickly converted conventional 3-point play to cut the CU lead to six, and also gave Swan her third foul. From there Roberson shined.
The San Antonio native scored 14 points in the first six minutes of the half as the Buffaloes began to pull away. She scored six in a row as CU rebuilt a double-digit lead at 46-35. After a pair of Hailey Houser free throws, CU put the game away with a 13-0 run. Following a Reese jumper and a transition layup from Lexy Kresl, Roberson scored the next seven as the Buffaloes won their fifth straight nonconference regular season game away from Boulder.
Nezianya led UMKC with 17 points and eight rebounds.
Colorado returns home to host the 26th annual Omni Hotels Classic Nov. 23-24 at the Coors Events Center. The tournament starts with Auburn vs. San Diego State on Friday, Nov. 23, at 5 p.m. followed by Colorado and Texas A&M-Corpus Christi at 7:30 p.m. On Saturday the consolation game will be played at 5 p.m. followed by the championship at 7:30 p.m.
