On Saturday, United Launch Alliance launched a Atlas V 401 rocket carrying NASA’s InSight Mars lander and two Mars Cube One (MarCO) miniature spacecraft known as cubesats. The pre-dawn launch from Vandenberg Air Force Base Space Launch Complex 3E in Lompoc, California was declared a success. This was the very first deep space launch from the west coast of the United States, and aimed to send a lander to the surface of the planet Mars to study its interior.

Launched alongside InSight were two MarCO cubesats, the first to be sent beyond Earth, nicknamed ‘WALL-E’ and ‘Eve’ after the protagonists of the 2008 animated science fiction film WALL-E. They were designed as a dual telecommunications relay for InSight during the spacecraft’s descent through the Martian atmosphere.

Traditionally, NASA launched interplanetary spacecraft at Cape Canaveral Air Force Station in Florida on the United States’ east coast. There, rockets were sent eastward over the Atlantic Ocean, borrowing the Earth’s rotational velocity to shoot their payloads out into the solar system. Due to congestion on the launch calendar at Canaveral, NASA chose to launch the spacecraft from from Vandenberg Air Force Base on the country’s west coast instead. A launch eastward from Vandenberg would have been dangerous due to densely populated areas being located downrange. Instead, rockets launched from Vandenberg were sent in a south-southeast trajectory. For Insight and MarCO, the spacecraft was placed in a temporary polar orbit after the launch, with the pair being shot towards Mars during a escape burn performed over the North Pole.

Despite a heavy fog settling in at the rocket’s launch pad in Lompoc, the United Launch Alliance declared a “100% chance of favorable weather for liftoff”. Spectators in Lompoc were treated to a mostly obscured view of the launch, though they were witness nonetheless to the sound and shock waves of the Atlas V’s Common Core first stage as it lifted the spacecraft off the ground on-schedule at 4:05 PDT (1105 UTC). People along the coast of southern California and northern Baja California, however, were in clear view of the Atlas V’s main engine burn and the first burn of the rocket’s Centaur upper stage. People in Orange County, California were treated to the sight of InSight and the Centaur almost eclipsing the planet Jupiter in the night sky.

The recently-inaugurated Administrator of NASA, Jim Bridenstine, congratulated the InSight team in an address televised live on NASA TV after the launch, along with the United Launch Alliance on what was their 128th successful launch in a row. The InSight mission part of NASA’s Discovery program, a class of low-cost solar system exploration missions. It was selected to launch in the program after beating the Comet Hopper and Titan Mare Explorer proposals amongst responses to a 2010 request.

Both InSight and the MarCO cubesats are en route to Mars. InSight carries eight scientific instruments, including a seismometer known as Seismic Experiment for Interior Structure (SEIS). The SEIS instrument will be recording the very first seismic measurements of Mars, which scientists hope will shed light on the structure of Mars beneath its surface. The lander was equipped with two cameras, based on the architecture of the Mars Exploration Rover’s navigation camera and hazard avoidance camera, to allow mission scientists to monitor the activity of the instruments. NASA scheduled a November 26 landing for InSight on a broad plain in the planet’s northern hemisphere, known as Elysium Planitia.

The US Food and Drug Administration (FDA) has issued proposed calorie labeling rules requiring most retail food vendors to display the calorie counts in items on their menus and menu boards. The proposed rules, issued Friday and expected to be finalized in 2012, would apply to most restaurants, snack bars, vending machines, coffee shops, drive-through restaurants, and convenience and grocery stores.

The US Congress required the rules in the health-care reform law passed in 2010. The rules proposed by the FDA must undergo a public comment period before they are finalized and take effect, said Michael R. Taylor, Deputy Director for Foods at the FDA.

The proposed regulations pertain to businesses devoting more than 50 percent of their floor space to the sale of food or that consider themselves restaurants, specifically food-selling chains with at least 20 stores nationally. Included are candy stores, bakeries, and ice-cream parlors.

The FDA’s proposed guidelines specify that chains post the calorie counts of foods and drinks on menus and menu boards or next to the food item, such as at a salad bar. The menu is to prominently exhibit the calorie content of each item in a way customers can see easily, giving them the same information packaged foods prepared at home currently provide. The information must be displayed in “clear and conspicuous” print and colors.

Many cities and states have passed laws requiring calorie labeling on menus, beginning with New York City in 2008. California implemented a similar law in January, although many counties are waiting for the release of the federal guidelines before they begin enforcement. Some fast-food chains there, such as McDonald’s and Starbucks, are displaying calorie counts on menus in some of their stores.

The rules are intended to curb the national obesity epidemic since, according to FDA estimates, one third of the calories people consume yearly come from food eaten out. In a statement issued yesterday, Kathleen Sebelius, Secretary of Health and Human Services said, “Giving consumers clear nutritional information makes it easier for them to choose healthier options that can help fight obesity and make us all healthier.”

Excluded from the rules are businesses whose primary product is not food sales but that sell it, such as bowling alleys, airports and airplanes, amusement parks, hotels and movie theaters. Alcohol is also excluded.

London, England — Yesterday at London’s Basketball Arena, the Canada women’s national wheelchair basketball team earned their first victory of the London Paralympics when they defeated the Australia women’s national wheelchair basketball team 57–50.

Canada took a one point lead into the second half, when the scores were 33–32 because of a last minute foul that sent Canada to the free throw line where they capitalized by making one of their shots. 4.5 point player Janet McLachlan and 2 point player Katie Harnock dominated in minutes played for Canada during the first half, playing all 20 minutes and leading their team in scoring with 11 first half points for McLachlan and 12 for Harnock. The Canadian team was loudly supported by spectators, earning more cheering from the largely Great Britain supporting fans than the Australians.

The second half saw Canada slowly increase their lead, keeping tied with Australia 4–4 in the first half of third, 6–4 in the last half of the third, 6–4 in the first half of the fourth, and 8–6 in the last half of the fourth. McLachlan finished the game as Canada’s leading scorer with 28 total, 17 in the second half. Harnock had a quieter second half only scoring 2 points to finish with 14. Cindy Ouellett was the team’s third leading scorer, finishing the game with ten.

The Canadian team supported their team from the bench, chanting “Get it out! Get it out!” when on defense and “Let’s go Canada” when on the offense. Other times, one player led the team in chanting support for their players on the court. The team was consistently louder than the Australian bench.

Throughout the game, the Canadians tipped themselves over more in their chairs than the Australians. Ouellett tipped once, and bounced in her chair, with a wheel leaving the ground as she attempted to block shots and steal the ball. Ouellett and Australian Cobi Crispin locked wheels, and required a break in the game where Australia’s coach came on to the court and removed Ouellett’s wheel to detach the pair before putting it back on again.

Following the game, Australia’s Amber Merritt said of playing Canada, “I have the utmost respect for Canada. They’re a great team, but we’ll refocus on the game tomorrow [against the Netherlands] and go out and play like we know we can, the Australian way.”

Prior to the start of the game, McLachlan was the team’s dominating player in the competition. She was ranked eighth in the competition in field goal percentage, and was Canada’a highest ranked player in this category. She ranked second in the tournament in total field goals made per game, with 12. Teammate Katie Harnock ranked eighth. Tara Feser ranked fourth in the tournament for 2 point field goal percentage at 57.1%, while McLachlan ranked ninth with 50.0%. McLachlan was second in 2 point field goals made per game, at 12. Harnock was tied for first with Mexico’s Floralia Estrada Bernal in the competition for 3 point field goal percentage at 20%, and was ranked second in the tournament for most 3 point field goals made with one.

As a team coming into the game, Canada was ranked sixth in total field goal percentage, eighth in free throw percentage, sixth in average rebounds per game, second in fouls, and last in turnovers.

Coming into this game, Canada had lost their first game 70–59 to the Netherlands. They are scheduled to play Brazil today.

This year’s Leisure Taiwan trade show (a.k.a Taiwan Sport Recreation and Leisure Show) started yesterday, with 131 companies participating including sports media companies such as ESPN and VideoLand Television, businesses selling sports equipment and fitness clubs.

There were also a variety of sports being played in the arena built for the trade show. The events included a 3-on-3 basketball tournament, free style shooting, and bicycle test-riding. In addition, conferences discussed issues related to sports and physical education.

A major topic in the trade show was energy-efficiency and, as a result, bicycles and similar sports equipment were being heavily promoted.

Next Tuesday, companies from the electronics industry plan to promote their industry at “2008 Digital E-Park.” In previous years, organizations from the electronics industry have showcased their products at Leisure Taiwan instead of at the Digital E-Park, so this move has reduced the number of markets covered by Leisure Taiwan.

In May, periodical cicadas with 17 years life cycle emerged on the East Coast of the USA after underground development as juveniles since 1996. Researchers and scientists worked to map and study the rare wave, and the locals prepared for the noisy event. First recorded in 1666, the Magicicada septendecim species recently emerged in 1979, 1996, this year, with a next wave due in 2030.

This week, Wikinews interviewed Chris Simon, an ecology and evolutionary biologist at University of Connecticut, about the cicadas.

((Wikinews)) What caused your initial interest in periodical cicadas?

Chris Simon: As an undergraduate student, I was interested in the formation of species so when I went to graduate school I looked for a study organism that was likely to be in the process of forming new species. I chose periodical cicadas because they are broken up into reproductively isolated broods (or year classes). Reproductive isolation leads to speciation so I planned to study biochemical differences among the broods.

((WN)) You study the emergence of the periodical cicadas. What do you study? What observations are you making?

CS: We record exactly where each cicada population emerges (using GPS automated mapping and crowd sourcing). We record the presence or absence of each of the three morphologically distinct species groups of periodical cicadas (Decim group, Cassini group, and Decula group). We collect specimens for DNA analysis. We look for cicadas coming up one and four years early and late. We dig up cicada nymphs and monitor their growth rates.

((WN)) What equipment do you use?

CS: Nets, shovels, automated GPS recorders, cameras, laptop computers, automated DNA sequencers.

((WN)) Do you study the periodical cicadas with anyone else? What is their role?

CS: Yes, there are a large number of people studying periodical cicadas in my lab and in other labs. My lab is made up of Research Scientists, Postdoctoral Researchers, a technician, graduate students, and undergraduates. Research Scientist John Cooley is the leader of the GPS mapping project; he invented the automated GPS recorder; he built our crowd-sourcing website, and he is instrumental in public outreach. Postdoctoral research David Marshall also participates in the mapping project and leads the part of the research related to the mapping of stragglers. John and Dave and Technician Kathy Hill all study periodical cicada mating behavior and conduct mating and hybridization experiments. One of my graduate students Beth Wade has participated in the nymph collections and will soon start genetic work involving genome wide association mapping designed to locate genes related to life cycle. My graduate student Russ Meister is studying the genes of the bacterial endosymbionts of cicadas. My current undergraduate honors student Erin Dwyer is also studying the development of Magicicada nymphs and is helping to design a lab exercise for college students around the eastern US to do the same. Many of my past undergraduate students have studied the biochemical genetics and development of periodical cicadas. See the Simon Lab website.

CS: We are collaborating with Teiji Sota at the University Kyoto and Jin Yoshimura at Shizuoka University in Japan. They are studying the phylogeography of Magicicada. We are collaborating with John McCutcheon of the University of Montana who is studying the endosymbiont genomes.

CS: We are also collaborating with ecologists Rick Karban and Louie Yang, both professors at UC Davis who have an interest in cicada population dynamics and nutrient cycling in the ecosystem.

((WN)) You studied the periodical cicadas in 1979 and 1996 too. What changes with time?

CS: I have studied periodical cicadas since I was a student back in 1974. What changes with time is increased human development constantly shrinking the patch size of cicada populations.

((WN)) What are your thoughts on the long life span of the periodical cicadas? Why could it be so? What advantages and what disadvantages does it have?

CS: Most or all cicadas have long life cycles compared to your typical annual insect. Examples have been found of two-year to 9-year cycles in different species. Periodical cicadas evolved an even-longer life cycle and I think that part of this relates to the evolution of their synchronized life cycles and peculiar safety-in-numbers strategy for survival. To become synchronized, periodical cicadas had to evolve an exact length life cycle and all adults would have to appear in the same year. Because the nymphs grow at different rates underground, a longer life cycle and a way of counting years must have evolved so that the individuals that get to the last nymphal (underground juvenile) stage first would wait long enough for all other individuals in the population to become ready to emerge.

((WN)) News reports mention this is ‘Brood II’ of the periodical cicadas. What are the distinctive features of this specific species and what is its full scientific name?

CS: The same species exist in multiple broods. No species is restricted to Brood II. The three species present in Brood II are: Magicicada septendecim, M. cassini, and M. septendecula. These same three species are found in every 17-year brood (except the farthest north which only has M. septendecim).

((WN)) At what depth do the cicadas juveniles live underground?

CS: Most live within the top foot of soil but some have been found deeper. We do not know if they go deeper in winter. We need to do much more digging to understand the nymphs.

((WN)) How do people prepare for the cicada emergence?

CS: Of course various people prepare in different ways. Ideally, everyone prepares by studying information available on the web (especially on our websites Magicicada Central and Magicicada.org).

((WN)) Do cicadas affect transport in the local area?

CS: No, not really. Occasionally individuals can be seeing flying across highways and sometimes they smash into cars.

((WN)) Do cicadas usually stay outside or do they also invade houses too?

CS: They stay outside. One might accidentally fly in through an open window but that would be rare.

((WN)) What do the cicadas eat?

CS: Cicadas suck xylem fluid (the watery fluid coming up from the roots of plants) in deciduous forest trees and herbs. Essential amino acids in the cicada diet are supplied by their bacterial endosymbionts. There are two species of endosymbionts. One makes 8 essential amino acids and one makes two essential amino acids.

((WN)) Do cicadas damage crops or city vegetation? What damage?

CS: Cicadas do not chew leave so they do not damage crops like other insects. They can inflict some damage by their egg laying. Cicadas lay eggs in pencil-sized tree branches. If there are not enough branches available, too many female cicadas may lay eggs in a single branch weakening it and making it susceptible to breakage by wind. This can sometimes cause damage in fruit orchards. If the branches break, the eggs die so this behavior is selected against by natural selection.

((WN)) Thank you.

CS: You’re welcome. I am happy to have this opportunity to communicate with your readers!
