CU president pushing for completion of US 36 bus rapid transit
Sep 12th
President Benson met with 36 Commuting Solutions and members of the US 36 Mayors & Commissioners Coalition on September 7 to discuss the delays in completing the corridor investments, including the RTD Bus Rapid Transit and Northwest Rail systems.
Due to the delay in completion of Northwest Rail for the foreseeable future, President Benson and the coalition believe that it is critical to complete true Bus Rapid Transit (BRT) as soon as possible. The President has pledged his help to engage corridor executives and our transportation partners to ensure the BRT system is in place by the opening of the managed lanes in 2015, including a dedicated vehicle fleet, greater service frequency, real-time travel info and station area improvements.
Benson said that success will only come through collaboration and stressed the importance of working with RTD, CDOT, businesses, communities and groups such as 36 Commuting Solutions to collectively solve the problem. “We all have a vested interest, and working together will help us all meet our common goal,” said Benson.
“We understand RTD’s cash flow to complete their remaining FasTracks investment to the corridor is delayed, but we believe there are other federal and state funding opportunities we need to collectively pursue,” said President Benson. “The corridor has my full commitment to keep these highly important projects moving forward in order to make US 36 the multi-modal corridor we truly need for it to be.”
DRCOG Approves $15 million for Phase 2 of the US 36 Express Lanes Project
<during their August board meeting, the Denver Regional Council of Governments (DRCOG) committed $15 million for Phase 2 of the US 36 Express Lanes Project, which will extend the express lanes from 88th Street to Table Mesa.
“This new funding from DRCOG brings us closer to completing Phase 2 of the project,” said 36 Commuting Solutions Chairperson, George Gerstle. “Though progress has been made, it is imperative that we secure the remaining funding needed to finish Phase 2 in order to make US 36 a truly multi-modal corridor.”

CU led mission to study past climate on Mars enters final phase before slated 2013 launch
Sep 11th
A University of Colorado Boulder-led mission to explore and understand how the loss of atmospheric gas has changed the climate of Mars over the eons has been authorized by NASA to proceed to system delivery, spacecraft integration, testing and launch, which is slated for November 2013.
The mission, NASA’s Mars Atmosphere And Volatile EvolutioN, or MAVEN, passed the critical agency milestone known as Key Decision Point-D, or KDP-D on Monday, said NASA officials. The key decision meeting moving MAVEN forward was held at NASA Headquarters in Washington and was chaired by NASA’s Science Mission Directorate.
“The spacecraft and instruments are all coming together at this point,” said CU-Boulder Professor Bruce Jakosky, the MAVEN principal investigator and associate director for science at the university’s Laboratory for Atmospheric and Space Physics, or LASP. “Although we’re focused on getting everything ready for launch right now, we aren’t losing sight of our ultimate objective — getting to Mars and making the science measurements.”
NASA’s $670 million MAVEN mission will be the first devoted to understanding the Martian upper atmosphere. The goal of MAVEN is to determine the role that loss of atmospheric gas to space played in changing the Martian climate through time. 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.
“I’m incredibly proud of how this team continues to meet every major milestone on schedule on its journey to Mars,” said David Mitchell, MAVEN project manager at NASA’s Goddard Space Flight Center in Greenbelt, Md. “Being ready for the start of system level integration and test is critically important to ultimately being ready for launch on November 18, 2013.”
KDP-D occurs after the project has completed a series of independent reviews that cover not only technical health of the project but also programmatic health, including schedule and cost. KDP-D represents the official transition from the Phase C development stage to Phase D in the mission life cycle. During Phase D, the spacecraft bus is completed, the science instruments are integrated into the spacecraft, spacecraft testing occurs and the MAVEN mission launches late in 2013.
Signs of water on Mars
The huge amount of public interest in NASA’s Curiosity Rover, which landed on Mars Aug. 6 and is currently being driven remotely around the planet, is no surprise to Jakosky. “Mars has a lot of similarities to Earth,” he said. “It’s the closest planet, it has similar day lengths, and it has an atmosphere, weather and geologic processes similar to those on our own planet.
“But the real kicker is the potential for life,” said Jakosky, who also directs the Center for Astrobiology at the University of Colorado. “Because of that, I think Mars has always held a special place in the hearts and minds of the public.”
Jakosky, also a professor in CU-Boulder’s geological sciences department, cautioned that there is much more work to be done before launch. “This decision by NASA marks the start of integration of all of the instruments on the spacecraft. It’s cool to see the spacecraft coming together, but there is a lot of work still to go and a lot of challenges to solve between now and when the spacecraft is ready for launch.”
The next major review for the MAVEN team is the Mission Operations Review in November 2012. This review assesses the project’s operational readiness and its progress towards launch. The project will continue to work with partners to deliver all instruments in the next four months.
“CU-Boulder’s participation in Mars exploration missions goes back decades, beginning with NASA’s Mariner 6 and Mariner 7 missions launched in 1969,” said Vice Chancellor for Research Stein Sture. “LASP is a proven training ground for students seeking hands-on experience in building, testing and flying space hardware and is the only institute in the world to have designed and built instruments that have been launched to every planet in the solar system.”
The MAVEN spacecraft will carry three instrument suites. The Particles and Fields Package, built by the University of California at Berkeley with some instrument elements from CU’s LASP and NASA’s Goddard Space Flight Center in Greenbelt, Md., contains six instruments that will characterize the solar wind and the ionosphere of the planet.
The Remote Sensing Package built by LASP will determine global characteristics of the upper atmosphere and ionosphere, while The Neutral Gas and Ion Mass Spectrometer, provided by NASA Goddard, will measure the composition and isotopes of neutrals and ions.
MAVEN will launch during a 20-day period in November-December 2013. It will go into orbit around Mars in September 2014, and, after a one-month checkout period, will make measurements from orbit for one Earth year.
In addition to leading the mission and providing instrumentation, CU-Boulder will provide science operations and direct education and public outreach efforts. NASA’s Goddard manages the project. Lockheed Martin of Littleton, Colo., is building the spacecraft and will perform mission operations. NASA’s Jet Propulsion Laboratory in Pasadena provides program management via the Mars Program Office, as well as navigation support, the Deep Space Network and the Electra telecommunications relay hardware and operations.
The MAVEN science team includes three LASP scientists from CU-Boulder heading instrument teams — Nick Schneider, Frank Eparvier and Robert Ergun — as well as a large supporting team of scientists, engineers and mission operations specialists.
MAVEN 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.

CU Boulder sends high school students experiments into space
Sep 11th
Space experiments dreamed up by three teenage winners of an international contest that will be streamed live on YouTube from the International Space Station Sept. 13 were made flight-ready by a University of Colorado Boulder space center.
The two winning experiments — one of which tests the ability of spiders to learn how to catch prey in the low-gravity of space, and the other which investigates how nutrients and compounds affect virulent bacteria growth in space — were announced in March. The contest is sponsored by YouTube, Lenova and Space Adventures with the involvement of NASA, the European Space Agency and the Japanese Space Agency.
“We took the ideas of the two winning experiments and transformed them into actual experiments that could be conducted in space,” said Stefanie Countryman, the business manager and outreach coordinator for BioServe Space Technologies, a NASA-sponsored center located in CU-Boulder’s aerospace engineering sciences department. The CU team also manifested the payload on an unmanned Japanese HTV rocket, conducted safety verifications and trained the astronaut flight crew on using BioServe hardware aboard the International Space Station, or ISS, for the project.
The global initiative sponsoring the contest is a new program known as YouTube Space Lab. YouTube Space Lab is one component of YouTube for Schools, a program that allows educators to access YouTube’s broad library of educational content from inside their school network. The contest generated more than 2,000 entries.
The student winners are Amr Mohamed, 18, of Alexandria, Egypt, who developed the idea for the spider experiment, and Dorothy Chen and Sara Ma, both 16, of Troy, Mich., who created the idea for the bacteria study. BioServe completed all of the mission integration and operations work for the two experiments and hand-delivered the loaded space flight hardware to the Tanegashima National Space Flight Center in Japan for launch to ISS on July 21.
The live, 45-minute YouTube Space Lab program stream from ISS, slated for 8:30 a.m. MDT on Sept. 13 will be hosted by Bill Nye “The Science Guy” and will include Mohamed, Chen and Ma. The winning experiments — selected by a panel that included British theoretical physicist Stephen Hawking, two NASA administrators, European Space Agency and Japanese Space Agency astronauts and Cirque de Soleil founder Guy Laliberte — will be performed by NASA astronaut Sunita Williams.
Countryman, who also will be part of the YouTube Space Lab live stream as she describes the role of BioServe in the project to Nye, said she was surprised by the sophistication of some of the experiments entered in the contest. “Seeing the level of intellect, not only from the top two winners but from six regional winners, makes us feel confident in the next generation of scientists and engineers,” she said.
Countryman said BioServe worked closely with Paula Cushing at the Denver Museum of Nature and Science and MaryAnn Hamilton of the Butterfly Pavilion in Westminster, Colo., to obtain the jumping spiders and analyze their behavior. BioServe designed, developed and built the flight habitat for the spiders. Once aboard ISS, the habitat will be placed inside a BioServe-built device known as a Commercial Generic Bioprocessing Apparatus, or CGBA.
In addition, BioServe worked with AgraQuest in Davis, Calif., a company that manufactures and sells the bacteria strain B. subtilis, which will be used in the experiment by Chen and Ma. BioServe researchers worked with the students to design the experiment, which included 48 fluid processing devices carried in six Group Activation Packs built by BioServe and which have flown on dozens of space missions.
BioServe also developed an HD camera system to record high-resolution still images and HD video of the spider habitat, which included both the arachnids and their food, fruit flies, Countryman said. One of BioServe’s CGBA devices on board ISS is providing power for the lighting system of the spider habitat and thermal control for both experiments, said Countryman.
As part of the contest, 14- to 18-year-olds, either alone or in groups of up to three, submitted videos describing their experiments to YouTube. All experiments submitted to the contest had to involve either biology or physics. People tuned into the YouTube Space Lab event can vote for their favorite experiments, Countryman said.
“For decades, one of our major thrusts at CU-Boulder’s BioServe Space Technologies has been to provide educational opportunities for hundreds of thousands of K-12 students around the world,” said Countryman. “This has been another opportunity for us to work with students on space payloads, a unique project that we hope will help steer many students from around the world into careers in the sciences.”
BioServe is a nonprofit, NASA-funded center founded in 1987 at CU-Boulder to develop new or improved products through space life science research in partnership with industry, academia and government, said BioServe Director Louis Stodieck. Since 1991 BioServe has flown payloads on 40 NASA space shuttle microgravity missions and additional payloads on several Russian and Japanese space vehicles.
YouTube, a video-sharing website, is a subsidiary of Google. Lenovo, a global company headquartered in Morrisville, N.C., is the world’s third-largest PC maker. Space Adventures, headquartered in Vienna, Va., provides flights for private citizens into space, including trips to the ISS.
