  • Mars Clock, by SunlightAndTime, is a 99-cent app that displays Mars time and a host of other Mars time goodies
  • for your Apple device
  • Features include local mean solar time for the rover, coordinated Mars time, sunrise and sunset times for the Curiosity landing site (I think this might be the coolest feature), current season, a countdown to landing feature (which is counting up since MSL landed on Mars on August 5th), current Earth time, a distance calculator between the Earth and Mars and radio communications delay estimate.

  • who are also deaf, signed up for the project just as the national Science Foundation funded the research
  • The team tested their system during a field trip visit to the Jean Messieu School for the deaf
  • Research from one of the tests revealed that the signer should be displayed in the center of the lens
  • deaf participants could look straight through the signer as they focused on a planetarium show.
  • This was particularly surprising for researchers as they believed that deaf students would prefer to have a video displayed at the top, as Google Glass normally presents itself
  • Researchers hope that with further studies, this tool can also be used for literary guidance

shared by Mars Base on 04 May 13 - No Cached
  • Researchers from the German "Loss of the Night" project have developed an app for Android smart phones, which counts the number of visible stars in the sky
  • The data from the app will be used by scientists to understand light pollution on a world wide scale.
  • The smartphone app will evaluate sky brightness, also known as skyglow, on a worldwide scale
  • ...7 more annotations...
  • This data can be used to map the distribution and changes in sky brightness, and will eventually allow scientists to investigate correlations with health, biodiversity, energy waste and other factors
  • The app works by interactively asking users to say whether individual stars are visible. By determining what the faintest visible star is, the researchers learn how many stars are visible at that location, and by extension how bright the sky is
  • With this app, people from around the world can collect data on skyglow without needing expensive equipment
  • some of the testers found that without intending too they learned the names of several stars and constellations
  • is based on the widely used Google Sky Map application
  • development of the app was sponsored by the German Federal Ministry of Research and Education,
  • satellites that observe Earth at night measure the light that is radiating into the sky, not the brightness that is experienced by people and other organisms on the ground

  • Just a week after a huge fireball streaked across the skies of the Chelyabinsk region of Russia, astronomers published a paper that reconstructs the orbit and determines the origins of the space rock
  • University of Antioquia in
  • Colombia used a resource not always available in meteorite falls: the numerous dashboard and security cameras that captured the huge fireball
  • ...9 more annotations...
  • Using the trajectories shown in videos posted on YouTube, the researchers were able to calculate the trajectory of the meteorite as it fell to Earth and use it to reconstruct the orbit in space of the meteoroid before its violent encounter with our planet.
  • The results are preliminary
  • and they are already working on getting more precise results
  • But through their calculations, Zuluaga and Ferrin determined the rock originated from the Apollo class of asteroids
  • due to variations in time and date stamps on several of the videos
  • some which differed by several minutes
  • they decided to choose two videos from different locations that seemed to be the most reliable
  • used this data and Google Earth to reconstruct the path of the rock as it entered the atmosphere and showed that it matched an image of the trajectory taken by the geostationary Meteosat-9 weather satellite.
  • From triangulation, they were able to determine height, speed and position of the meteorite as it fell to Earth

  • a Grade 10 student
  • designed a flashlight that provides bright light without batteries or moving parts
  • and only needs a five degree temperature difference to work and produce up to 5.4 mW at 5 foot candles of brightness
  • Using four Peltier tiles and the temperature difference between the palm of the hand and ambient air
  • bought Peltier tiles and tested them to see if they could produce sufficient power to light an LED
  • power was no problem but getting the needed voltage was, as the tiles did not generate enough of the voltage needed
  • some changes to the circuit design
  • used the Internet for information, experimented with different circuits
  • finding an energy-harvesting article
  • that made note of a circuit that could provide enough voltage when used with a recommended transformer
  • The final design included mounting the Peltiers on a hollow aluminum tube which was inserted in a larger PVC pipe with an opening that allowed ambient air to cool the tube
  • The palm wrapped around a cutout in the PVC pipe and warmed the tiles.
  • The result was a bright light at 5 degree Celcius [sic] of Peltier differential
  • Materials for the flashlight project cost her $26
  • The top winner gets a $50,000 scholarship and trip to the Galapagos Islands
  • The prize ceremony takes place in September. Winners will be chosen in different age categories—13-14, 15-16, 17-18.
