ScienceCast: Early start for noctilucent clouds

The latest NASA ScienceCast reports on noctilucent clouds, which are formed at very high altitudes (75 to 85 km) from water vapor condensing onto dust grains that apparently come from meteors:

Glowing electric-blue at the edge of space, noctilucent clouds have surprised researchers by appearing early this year. The unexpected apparition hints at a change in the “teleconnections” of Earth’s atmosphere

Update on Univ. Washington fusion propulsion project

Here’s an update on the nuclear fusion propulsion system that John Slough and his team at the University of Washington’s Plasma Dynamics Lab is developing: Scientists Testing Nuclear Fusion-Powered Rocket Engine – The Daily Fusion.

See also the descriptions of the project funded by the  NASA Innovative Advanced Concepts (NIAC) program:

The overall FDR [Fusion Driven Rocket] system ranges from relative high TRL [Technical Readiness Level] components (such as the FRC [Field Reverse Configuration] formation system) down to very low TRL components (such as the fusion compression chamber). The lower TRL components have been the focus of the NIAC phase I effort and will be developed to higher TRL throughout the phase II of this project. A Concept Validation Experiment will be conducted during the phase II effort with the possibility of demonstrating fusion gain if successful. It is expected at this point that NASA will have a strong interest in fully developing this system, and integrating it into their future space flight planning. With adequate resources a subscale ground demonstration could be realized as soon as 2017 and an in-space demonstration mission as early as 2023.

Sci-Tech: Simple, cheap infrared camera for DIY scientists

A reader points to an interesting citizen-science crowd-funding campaign: Infragram: the Infrared Photography Project by Public Lab — Kickstarter (they have far exceeded their goal and still have 26 days left) :

A simple, cheap infrared camera which can measure plant health — for geek gardeners, farmers, and open source DIY scientists.

What could farmers, gardeners, students or environmental activists do with an infrared camera that costs as little as $35?

What is Infragram?

Infragram is a simple, affordable near-infrared camera produced by the Public Laboratory community in a series of collaborative experiments over the last few years. We originally developed this technology to monitor wetlands damages in the wake of the BP oil spill, but its simplicity of use and easy-to-modify open-source hardware & software makes it a useful tool for home gardeners, hikers, makers, farmers, amateur scientists, teachers, artists, and anyone curious about the secret lives of plants.

What can you do with Infragram?

  • Monitor your household plants
  • Teach students about plant growth and photosynthesis
  • Create exciting science fair projects
  • Generate verifiable, open environmental data
  • Check progress of environmental restoration projects
  • Pretend you have super-veg-powers

NASA Sample Return Robot Challenge competition update

None of the robots fielded by 11 teams in NASA’s Sample Return Robot Challenge completed the requirements to win the $1.5M competition in this years event, which was held at Worcester Polytechnic Institute (WPI) June 5-7 in Worcester, Massachusetts. The goal is to “demonstrate a robot that can locate and collect samples from a wide and varied terrain, operating without human control.”

There was, however, considerable improvement in overall performance as compared to the event last and one team did complete the first phase and received a $5k prize for that accomplishment.

WPI is managing the contest, which has been held twice so far. There will be presumably be another competition event next year. Here are two WPI sites related to the challenge:

Here’s a local article about the competition:  Party at WPI – Worcester Telegram & Gazette – telegram.com.

And here is an official press release from NASA:

NASA Awards Sample Return Robot Centennial Challenge Prize

After two days of extensive competition, Team Survey of Los Angeles was awarded $5,000 in prize money after successfully completing Level 1 of the Sample Return Robot Challenge, a part of NASA’s Centennial Challenges prize program.

The event, hosted by Worcester Polytechnic Institute (WPI) June 5-7 in Worcester, Mass., drew robotics teams from the United States, Canada and Estonia to compete for a total of $1.5 million in NASA prize money. Eleven teams arrived to compete at WPI; 10 teams passed the initial inspection and took to the challenge field. After two rounds of Level 1 competition, Team Survey met the $5,000 prize requirements and was declared the winner of this year’s competition.

Team Survey members Jascha Little, Russel Howe, Zac Lizer, Tommy Smith, Zoe Stephenson, Scott Little, Brandon Booth, and Joanna Balme, all from Los Angeles, were presented a check June 8 by NASA’s Larry Cooper, Centennial Challenges program executive, at the opening of the TouchTomorrow technology festival. A WPI organized science and robotics festival attracted thousands of attendees, showcasing the teams and robots as well as NASA and WPI exhibits in science, robotics and space technology.

“It is evident from the level of improvements the teams have shown from last year’s event to this week’s Level 1 win that the technology has significantly progressed, and the desired results of this challenge are within reach,” said Sam Ortega, program manager of Centennial Challenges. “We are so proud of the great spirit and camaraderie the teams have shown, as well. It speaks volumes about the caliber of teams and individuals who compete in these events.”

NASA uses prize competitions to increase the number and diversity of the individuals, organizations and teams that are addressing a particular problem or challenge. Prize competitions stimulate private sector investment that is many times greater than the cash value of the prize and further NASA’s mission by attracting interest and attention to a defined technical objective.

To win prize dollars, teams were required to demonstrate a robot that can locate and collect samples from a wide and varied terrain, operating without human control. The objective of the challenge was to encourage innovations in autonomous navigation and robotics technologies.

Team Survey’s robot successfully completed Level 1 by navigating from the starting platform and locating a sample that was previously identified in the robot’s onboard computer. The robot then autonomously returned one undamaged sample to its starting platform within the 30-minute time limit. No teams made it to the second level of the competition this year.

Returning teams this year included SpacePRIDE of Graniteville, S.C.; Survey of Los Angeles; Wunderkammer of Topanga, Calif.; Intrepid of Lynnwood, Wash.; and the University of Waterloo in Ontario, Canada. New teams entering the competition this year were Fetch of Alexandria, Va.; Middleman of Dunedin, Fla.; Mystic Lake Robots of The Woodlands, Texas; Team AERO of Worcester, Mass.; the Autonomous Rover Team of the University of California at Santa Cruz; and Kuukuglur of Estonia.

NASA’s Centennial Challenges program is part of the agency’s Space Technology Mission Directorate, which is innovating, developing, testing and flying hardware for use in NASA’s future missions.

FISO: METERON and its related robotics Technologies at ESA Telerobotics & Haptics Lab

The latest presentation to the Future In-Space Operations (FISO) study group is now posted in the FISO Working Group Presentations Archive. The  slides and videos (zip) and audio (mp3) are available for the talk, METERON and its Related Robotics Technologies at ESA Telerobotics & Haptics Lab – Part 2,  André Schiele , Delft Univ of Technology & ESA/ESTEC – May 29, 2013.

A zip file is used this time since the

presentation by André Schiele includes a pdf, and a set of 8 short mp4 videos. When you open the pdf, you will be pointed to these videos (by number, as in “Video1 – EXARM / PA10 Telerobotics Workcell”) which you can open by clicking on the mp4 file by that name, OR by calling them up by clicking on the YouTube link on the page, if you happen to be internet-connected. These videos will NOT automatically launch in the pdf document.

Here are a couple of the videos from the TeleroboticsLab YouTube channel:
