UA's Latest Space Robot Stops By Earth, Sends Snapshot of the Planet

OSIRIS REx, Tucson’s favorite space bot, swung by the earth last Friday to say hello, take some pics, and to borrow some of the planet’s gravity in order to launch off toward the asteroid Bennu, the spacecraft’s destination site.

“We made the decision to to use nature to help us to get us to our destination,” said Heather Enos, deputy principal investigator of the OSIRIX REx mission. “What that means is we actually used the earth’s gravity in order to propel us onto our destination into the orbital plane necessary to match our target, Bennu."

While it was nearby, the OSIRIS REx team used the opportunity to recalibrate the spacecraft’s instruments, including the MapCam camera. MapCam captured this image on Sept. 22, from a vantage point 170,000 kilometers (or 106,000 miles) away from the earth. It's largely of the Pacific Ocean, but you can see Australia in the lower left and Baja California in the upper right.

Dante Lauretta, the principal investigator of the UA-led NASA mission, said the photo represents one of his favorite new angles of the earth.

"What if we were an alien species and we sent a flyby spacecraft to the earth and they took this picture?" he asked "It really looks like it is an ocean world... It is a nice reminder of how beautiful and important the oceans are, and our planet is."

The black marks at the top of the photo—the OSIRIS REx team calls them "icicles"—are the result of a camera designed to take pictures of a very dark (darker than coal) asteroid trying to take pictures of a very bright earth.

"[This] meant we had to take the images as fast as possible, and as a result of that very fast data acquisition rate, there [were a few] readout issues," Lauretta said.

Lauretta described Friday and Saturday as the second most exciting days of the mission so far—besides, of course, the day of the launch. The team spent Friday evening huddled around their monitors and waiting for the images to arrive. When one of the team members finally pulled it up, a mad scramble ensued to get the image up on the big screen, and the whole team was left in awe.

"It felt like I was actually in space and I was looking at that image," Lauretta said. "Because OSIRIS REx is us. We built it, and we own it and we really feel like it's a projection of ourselves that's out there exploring the solar system."

Follow OSIRIS REx on Twitter or Instagram, and see the OSIRIS REx website to learn more about the mission.

  • The vista seen while walking up Tumamoc Hill.

The climb up Tumamoc hill has historically been closed to the public from 7:30 a.m. to 5:30 p.m. in order to help preserve resources and, presumably, to prevent the trail from turning into a waterfall of sweat from people attempting the hike in the middle of the day.

Until now! Starting Sept. 5, the UA will be extending public access hours from 4 a.m. to 10 p.m. for a solid 18 hours of available hiking time a day. Fencing will be installed at the top to mark the end of the trail and to continue preserving surrounding areas.

In addition, a new app, the Tumamoc Tour, will soon be available in both English and Spanish and for both iOS and Android devices. Narrators David Yetman and Alberto Burquez (English and Spanish, respectively) will tell the story of Tumamoc Hill and its place in the Sonoran Desert. Accompanied by the music of Calexico and Gabriel Naim Amor, the app’s six sections and 16 YouTube video will help listeners understand the significance of the reserve and the research, education and preservation missions it is a part of.

Museums

Space Night 2017. Sleepovers at friends’ houses are fun, but are they educational? Are there opportunities to use state-of-the-art telescopes? Are there real meteorites available to be touched? We didn’t think so. The Children’s Museum Tucson will be showing sleepover guests how to get a party started with pizza, pajamas, binoculars, thermal cameras, and even meteorite-touching ops. Families are welcome to pitch tents in designated areas in the museum and in the main courtyard, for that highly sought after “pitch-a-tent-in-the-living-room-or-backyard-but-still-be-surrounded-by-fascinating-artifacts-and-unique-educational-opportunites” feel that many a sleepover party host has strived for and not attained. 6 p.m. to 9 a.m. Saturday, Aug. 26 to Sunday, Aug. 27. Children's Museum Tucson 200 South Sixth Ave. $50, $45 for museum members.

Music and Healing: Since Pursuing Music, Arizona Teenager Hasn't Missed a Beat

Posted By on Wed, Mar 15, 2017 at 9:30 AM

Marthajane and Trey Vincent stand outside of The Berger Performing Arts Center  on Sunday, Feb. 26. This was Trey's first opportunity to play a full set list of his choosing. - HAILEY FREEMAN

  • Marthajane and Trey Vincent stand outside of The Berger Performing Arts Center on Sunday, Feb. 26. This was Trey's first opportunity to play a full set list of his choosing.
Music has the power to stir up vivid memories, unlock creativity, inspire the unmotivated, and evoke within us the entire spectrum of human emotion. It connects people across cultures and eras and helps us celebrate, mourn, and entertain. On occasion, it aids us in showcasing subpar dance moves.

In certain instances, music facilitates healing. Such is the case for 13-year-old Trey Vincent.

Trey’s life was filled with music even before his autism diagnosis at age two. Right around the time Trey’s mother, Marthajane Vincent, began noticing her son’s atypical development, she also observed his natural inclination toward music.

Trey did not make eye contact, became stiff when comforted, remained nonverbal and ignored others speaking to him. But he paid attention to The Wiggles and Baby Einstein videos.

“One thing we hit on that he really engaged with was music,” Marthajane said. “He would clap his hands and do normal baby things while listening.”

Entering neurologic music therapy as a toddler strengthened Trey’s social functioning and cognitive skills, according to Marthajane. In Trey’s program, the music therapist’s guitar playing gave the children something to interact around. Through peer modeling, Trey learned how to pick up on social cues. While playing the percussion in music therapy, Trey worked on crossing the midline. By following certain rhythms and instructions, Trey developed his motor skills and improved his left-right brain connections. Music therapy can help individuals across the autism spectrum.

Learn How To Save the Bees

Posted By on Mon, Mar 6, 2017 at 2:30 PM

No, the buzzing you hear isn't the iPhone in your pocket. It's a honey bee—and the impact it has on pollinating the crops you eat is worth its slightly obnoxious presence.

The importance of bees to our ecosystems and to the development of food we eat is no secret, but the preservation of the insects gained an increase in support recently since six species of yellow-faced bees joined the U.S. Fish and Wildlife Endangered Species List. The Southern Arizona Work Space will be hosting a class, The Basics of Beekeeping, on Saturday, March 11 from 1-3 p.m. to teach people the craft of beekeeping or what to do if they find a swarm or hive in their own backyards. Admission is $20. As a sweet incentive, there will also be a honey tasting.

  • RVC Outdoor Destinations
Beekeeping may be becoming a lost art—and an important one too. If anyone needs more convincing of why saving honey bees is important, check out these fun facts according to RVC Outdoor Destinations:

-Their tiny wings can flap up to 200 times a second, allowing them to buzz around up to 15 mph.

- Much like a last call might look like in a downtown club, communication takes form in a frantic "dance" called a "waggle."

- Bees can recognize a human face. So yes, they can actually see your terrified expression as you run away squealing.

If you still need encouragement to push aside your fears, just look up #savethebees on Twitter and read what much funnier people have to say about the issue.

Ticket Giveaway: Brujeria with The Casualties, Pinata Protest, Flying Donkey Punch, Maldad, Napalm Strike

Posted By on Thu, Jan 12, 2017 at 11:12 AM


Brujeria is a frighteningly punchy all-star death metal/grindcore combo that passes itself off as a murderous, truly evil drug cartel, one into Satan worship and Donald Trump. (Brujeria is Spanish for “witchcraft.”) Yes, they’re lampooning the form, but the music absolutely holds up as some of the heaviest shit ever recorded this side of Scandinavia. So let’s not confuse such skull-splitting din with lightweights like Spinal Tap or Gwar, OK?

It’s no surprise members of Carcass, Cradle of Filth, Dimmu Borgir and Napalm Death fill out the lineup. They’ve been together in one form or another since 1989 and their long-awaited fourth album, Pocho Aztlan, dropped a few months back.

Catch them with The Casualties, Piñata Protest, Flying Donkey Punch, Maldad, and Napalm Strike. at 6 p.m. on Friday, Jan. 13 at The Rock, 136 N. Park Ave. You can buy tickets for $23 a piece or enter to win a pair of tickets from us. Just fill out the form below and keep checking your email—we'll be in touch with winners around noon the day of the show.

Three (Maybe Four) Energy Stories From the News

Posted By on Wed, Jan 11, 2017 at 9:06 AM

PHOTOSPIN
  • Photospin
If you go to to Friday's New York Times and AZ Star, you'll find these three energy-related articles:

Sensing Gains Ahead Under Trump, the Kochs Court Minorities. The Koch Brothers have begun a well-funded, new nonprofit business association, Fueling U.S. Forward, which is spreading the fossil fuels gospel to minority communities — almost literally, by funding gospel concerts where Hosannas are sung in praise of God, Coal, Oil and Natural Gas.

Arizona Corporation Commission urged to fix solar net metering 'grandfathering' issue. The ACC slashed the compensation rooftop solar owners will receive for excess energy generation that makes its way onto the grid. The ACC is being asked to improve one small part of a very bad decision by amending the grandfathering rules so people who submit their energy interconnection applications before the deadline will receive the current net metering compensation, as well as people who have their interconnections completed by the deadline. [Note: On Tuesday the ACC amended the rules to include those who submit applications before the deadline.]

China Aims to Spend at Least $360 Billion on Renewable Energy by 2020. China is funding a huge push to add renewables to its energy grid, both to lower its ridiculously high pollution levels and to try and dominate the world's growing renewable energy markets.

To sum up: U.S. cities have less pollution than they had decades ago and far less pollution than China's smog-choked cities, but courtesy of the expected pro-fossil-fuels, anti-regulation push from the Trump administration, we may slide backwards while China pushes forward. The Brave New Trump Era could harm our environment and our health while it slows our technological advances in the renewable energy arena and loses us potential business worldwide.

The headline for a fourth story from a few days ago reads, Arizona still a force in solar power, despite other states' gains. It's about our growing solar energy sector, which is second in the nation to California. Apparently, we're OK with private businesses setting up vast solar power arrays so they can make lots of money off our abundant sunshine, but we're not so OK with encouraging individual homeowners to fill unused space on their rooftops with solar panels by giving them fair compensation for the energy they produce. Corporate and home solar both reduce our dependence on fossil fuels, but home solar can also reduce corporate profits, and that's just not the Arizona way.
