By STEPHANIE SALMONS Hawaii Tribune-Herald | Monday, October 29, 2018, 12:05 a.m. Aaron Roth is shooting for the stars. Literally. When the 2015 Waiakea High School graduate earns his diploma from Ariziona State University next spring, the computer science major already has a job lined up — with NASA’s Jet Propulsion Laboratory in California. According to its website, the Jet Propulsion Laboratory is the leading U.S. center for robotic exploration of the solar system. It has 19 spacecraft and 10 major instruments carrying out planetary, Earth science and space-based astronomy missions. Roth, who was raised in Hilo, said he has always liked computers, but Waiakea High’s robotics program was a “huge, contributing factor that got me interested in everything.” He did well in robotics and even took first place in an international competition. “Robotics was, like, behind my passion then PISCES got me really into space.” Roth interned for the Pacific International Space Center of Exploration Systems, a state-funded aerospace agency based in Hilo, during the summers of 2016 and 2017, where he worked on a stereoscopic camera system for the Helelani rover. With that work, Roth said he was able to help provide anaglyphs of the things the camera captured and disparity maps, which help better gauge the distance of an object. “Aaron interned with PISCES during two consecutive summers and completed some great work on our analog planetary rover,...
Hikianalia and Hokulea Arrived In Tahiti and Coming Home Soon!

Hikianalia and Hokulea Arrived In Tahiti and Coming Home Soon!

The Hikianalia departed Hilo March 26th (shown in photo) with one of PUEO’s founders and Keaukaha Community leader Uncle Pat Kahawaiola’a blessing their departure.  Their goal was to meet up with Hōkūleʻa and bring them some materials for repairs before they had back to Hawaii. They arrived safely in Tahiti following the stars and waves to join up with Hōkūleʻa on their round the world trip to bring them some repair materials and accompany them on the final legs of the voyage back home.  After sailing about 100 miles from Papeete, Tahiti, the canoes arrived at Taputapuatea on the morning of April 25, 2017 following the historic protocol of entering via the sacred pass of Teava Moa.  You can follow Hikianalia’s activities here: http://www.hokulea.com/crew-blog-kalepa-baybayan-follow-wind/ and Hokulea’s here http://www.hokulea.com/blog/ The should be back in Hawaii in June!...
Mars Simulation Ends after 1 Year on Mauna Loa

Mars Simulation Ends after 1 Year on Mauna Loa

By TOM CALLIS Hawaii Tribune-Herald Six scientists will become the first to complete a yearlong Mars simulation in the United States when they exit a small dome Aug. 28 on Mauna Loa. For nearly 365 days, the crew has seen the outside world only through a small porthole or through the lens of their spacesuits, which they must wear to venture outside. At 8,200 feet above sea level, the landscape mimics Martian soil somewhat, with hardly any vegetation to be found. “They’re doing OK as far as we can tell,” said Kim Binsted, principal investigator for the Hawai‘i Space Exploration Analog and Simulation. The University of Hawaii runs the NASA-funded study. Three other simulations have been held in the dome, located in a former quarry, for four- and eight-month durations. Each scientist works on research projects during their stay and learns how to manage limited resources while avoiding personal conflicts in isolation. Any communication with the outside world is put on a 20-minute delay, the length of time it would take to relay messages to and from the red planet. Binsted said the only longer simulation held was a 520-day mission in Russia that mimicked a trip to Mars. HI-SEAS is more focused on what a crew will do once they get there. The crew will be provided fresh fruit and other food not available during the simulation after they leave the dome. “They are clamoring to get into the ocean,” Binsted said. “I think they will enjoy having a beer as well.” Binsted said HI-SEAS will host two more eight-month simulations, with the next one starting in January....
Maunakea Skies: Future of UH Hilo Astronomy Program Talk Aug 19th

Maunakea Skies: Future of UH Hilo Astronomy Program Talk Aug 19th

[source] University of Hawai‘i at Hilo astronomy majors will receive more hands-on telescope time than ever before as the result of a recent agreement between the Institute for Astronomy at UH Mānoa and the Department of Physics and Astronomy at UH Hilo. These students have a unique opportunity afforded to few other programs in the country—the opportunity to study the universe in the world’s largest observatories for optical, infrared and submillimeter astronomy on the 13,000-foot-high summit of Maunakea. Dr. Marianne Takamiya, associate professor of astronomy and chair of the Department of Physics and Astronomy at UH Hilo will present an update on these and other developments in UH Hilo’s astronomy program at ‘Imiloa Astronomy Center’s Maunakea Skies talk on Aug. 19 at 7 p.m. ‘Imiloa Astronomy Center photo. “I will present the latest results of the research of faculty and students in astronomy, how our academic program has developed in the last five years and what we envision for the future,” stated Takamiya. “UH Hilo has unique elements that can make ours a novel astronomy program that produces not only astronomers, but also skilled professionals who are able to work in complex systems.” ‘Imiloa Astronomy Center photo.

Gemini Telescope finds Jupiter Moon Io’s Atmosphere Collapses and Reforms

Gemini Telescope finds Jupiter Moon Io’s Atmosphere Collapses and Reforms

Gemini observations show that the thin atmosphere of Jupiter’s moon Io undergoes dramatic changes during frequent eclipses with the giant planet. The following press release, issued by the Southwest Research Institute, explains how the dramatic changes in temperature cause the moon’s atmosphere to collapse. Research reveals freezing effects of Jupiter’s shadow on moon’s volcanic gases San Antonio – Aug. 2, 2016 – A Southwest Research Institute-led team has documented atmospheric changes on Io, Jupiter’s volcanically active satellite, as the giant planet casts its shadow over the moon’s surface during daily eclipses. A study led by SwRI’s Constantine Tsang concluded that Io’s thin atmosphere, which consists primarily of sulfur dioxide (SO2) gas emitted from volcanoes, collapses as the SO2 freezes onto the surface as ice when Io is shaded by Jupiter. When the moon moves out of eclipse and ice warms, the atmosphere reforms through sublimation, where ice converts directly to gas. “This research is the first time scientists have observed this phenomenon directly, improving our understanding of this geologically active moon,” said Tsang, a senior research scientist in SwRI’s Space Science and Engineering Division. The findings were published in a study titled “The Collapse of Io’s Primary Atmosphere in Jupiter Eclipse” in the Journal of Geophysical Research. The team used the eight-meter Gemini North telescope in Hawai’i with the Texas Echelon Cross Echelle Spectrograph (TEXES) for this research. Data showed that Io’s atmosphere begins to “deflate” when the temperatures drop from -235 degrees Fahrenheit (-148 ℃) in sunlight to -270 degrees Fahrenheit (-168 ℃) during eclipse. Eclipse occurs 2 hours of every Io day (1.7 Earth days). In full...
The Science Behind Hawaii’s ‘Smiley Face’ Volcano

The Science Behind Hawaii’s ‘Smiley Face’ Volcano

[source] A “smiling” volcano has gone viral. Hawaii’s Kilauea volcano has been actively erupting since 1983, and it’s one of the most active volcanoes in the world, according to the U.S. Geological Survey (USGS). But the volcano received more attention recently when the volcano’s lava formed what looks like a smiley face. The smiley face appeared in a lava lake crater on the west flank of Pu’u ‘O’o, on Kilauea’s East Rift Zone, according to Janet Babb, a geologist with the USGS’ Hawaiian Volcano Observatory. [Explosive Images: Hawaii’s Kilauea Erupts for 30 Years] Pu’u ‘O’o also recently made headlines when the lava flow reached the ocean for the first time in three years. While it may seem like Kilauea was smiling for the cameras, the “face” has a more scientific explanation: The bright spots and incandescent line that created the face shape were produced by normal volcanic activity. As a lava lake circulates, lava upwelling and downwelling will occur on opposite sides of the lake, according to the Hawaiian Volcano Observatory. This often results in a spattering of molten lava, which creates bright spots on the dark-colored, semi-solid lake surface. Circulation can also cause sections of the surface to pull apart, revealing the lava beneath and creating lines. By chance, these processes occurred in a pattern that created the smiling image, Babb said. “The Pu’u ‘O’o lava lake just happened to produce two spattering sources (bright dots) that have been interpreted as ‘eyes’ and an incandescent line that has been interpreted as a ‘mouth’ — with the two lake surface features located relative to each other to produce the...
