NASA’s Newest Mars Mission Spacecraft Enters Orbit around Red Planet

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit on September 21, where it now will prepare to study the Red Planet’s upper atmosphere as never done before.  MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.

“As the first orbiter dedicated to studying Mars’ upper atmosphere, MAVEN will greatly improve our understanding of the history of the Martian atmosphere, how the climate has changed over time, and how that has influenced the evolution of the surface and the potential habitability of the planet,” said NASA Administrator Charles Bolden.  “It also will better inform a future mission to send humans to the Red Planet in the 2030s.”

After maneuvering into its final science orbit and testing its instruments and science-mapping commands, MAVEN will begin its one Earth-year primary mission, taking measurements of the composition, structure and escape of gases in Mars’ upper atmosphere and its interaction with the sun and solar wind.  The primary mission includes five “deep-dip” campaigns, in which MAVEN’s periapsis, or lowest orbit altitude, will be lowered from 93 miles (150 kilometers) to about 77 miles (125 kilometers).  These measurements will provide information down to where the upper and lower atmospheres meet, giving scientists a full profile of the upper tier.

MAVEN launched November 18, 2013, from Cape Canaveral Air Force Station in Florida, carrying three instrument packages. 

Orionid Meteor Shower

Each year, October brings us an entertaining celestial light show in the form of the Orionid meteor shower.  The Orionids are named, as is customary with meteor showers, after the point in the sky called the shower's "radiant" from which the meteors appear to fan out (in this case, the radiant lies within the constellation Orion).  Several well-known meteor showers occur around the same dates each year, for these showers mark the points in Earth's orbit where our planet passes through the dusty debris from some comet.  The Orionids are one of two showers that mark our planet's passage through the dust trail left behind by Halley's comet!

This year, October 21 is estimated to be the peak of the Orionids.  The shower will be most active between midnight and the wee hours before dawn, averaging around 20 meteors per hour to a maximum of 60 meteors per hour.  Luckily, this year, the moon phase will be close to new, so the sky should be wonderfully dark!

Be a Scientist for Halloween!

Were your students planning to be princesses, vampires, or characters from Minecraft this Halloween?  They can try something different this year and dress up as famous scientists!  Here are some ideas:

Albert Einstein - That's easy!  You can get an Einstein wig and moustache in any costume store.  Wear a white lab coat and dark pants, and put a few pens and a ruler in your lab coat pocket.

Sir Isaac Newton - You will need long blonde hair or a wig for this one.  A velvet jacket and a long white scarf (borrow from Mom!) will make you look just like the famous portrait of Newton.  Don't forget the apple!

Galileo Galilei - Wear a long, dark, belted jacket and dark stockings with a large, white collar.  Glue on a beard and carry a telescope.

Socrates (Euclid, Archimedes, Aristotle, or any other ancient Greek philosopher!) - Drape a white sheet around your body and over your shoulder.  Wear a white t-shirt underneath.  Glue on a beard and hold a sheet of paper with some geometrical drawings rolled to look like a scroll.

You can also try other fun science-related costumes  - an astronaut, a robot, an explorer, or an animal.  Have a great Halloween!

Daylight Saving Time

Daylight Saving Time (DST) ends on November 2nd this year in most of the U.S.  Don't forget to turn your clocks one hour back.  Daylight Saving Time (or Summer Time as it is called in many countries) is a way of getting more light out of the day by advancing clocks by one hour during the summer.

Ancient civilizations had to adjust daily schedules to the sun more flexibly than we do.  Romans divided daylight into 12 equal hours, so the length of each hour was longer during summer.  In 1784, Benjamin Franklin, then an American envoy to France, anonymously published a satirical letter suggesting that Parisians economize on candles by rising earlier to use morning sunlight.  The New Zealand entomologist, George Vernon Hudson, first proposed modern DST in 1895.  English builder, William Willett, independently conceived of DST in 1905 when he noticed during an early summer morning ride that many people were still sleeping.  He became an advocate of DST but didn't live to see it adopted.  Many European countries started to switch their clocks in 1916, in an effort to conserve fuel during World War I.  The United States adopted DST in 1918, but it was inconsistent till 1966, when President Johnson signed The Uniform Time Act.

Different nations start and end DST on different dates.  In the Southern hemisphere, beginning and ending dates are reversed.  Some nations shift time year-round, and some do not observe DST at all.  And just to keep you on your toes, sometimes different areas of one country have different time shifts!

Surface Ocean Currents - A Resource for the Upper Elementary Classroom

Check out our resource on surface ocean currents for the upper elementary classroom!  The Ducks in the Flow module is intended for grades 3-5 and includes a storybook and three classroom activities.

In the storybook, three kids work collaboratively to explore and investigate surface currents found in the ocean and the Great Lakes while learning about the journey of a seafaring plastic duck.  Three hands-on activities for the classroom further explore the science content and provide instruction in basic science process skills.

Learn about Reptiles!

It turns out that snakes are the most feared of any animal on Earth. Reptiles have had a consistently bad rap for a long time - from the serpent in the Garden of Eden to the basilisk of Lord Voldemort. Reptiles are seen as sinister, scaly, deceitful and more than a bit threatening.

But did you know that rattlesnakes, some of the most feared snakes of North America, bear live young and some actually stay with their young after birth to teach them life habits? That sounds more maternal than threatening! Rattlesnakes (and many other reptiles) are responsible for controlling the population of rodents and insects whose populations would otherwise grow uncontrollably. Snakes serve as a food source for birds, other reptiles, and mammals, thus supporting the natural ecosystem that is home to many plants and animals. Rattlesnakes are actually docile snakes that will try to escape rather than fight. They will, of course, famously shake their rattle as a warning sign to let humans and other creatures know to stay clear. Like any wild animal, snakes should be treated with respect - and it's always best to leave handling to the experts.

When out hiking in mid-Maryland this past June, a friend and I (and my two young children) came across a copperhead in the wild. He was basking in the dark earth of the path we were hiking. We walked around the snake and not over it. My friend dared to take this close-up shot of its head. The photo makes the copperhead, a native venomous snake to Maryland, look menacing, but the snake couldn't have been more docile! An hour later, on our return hike, the snake sat in the same spot it had been, soaking up warm summer rays. We walked around it and marveled at its camouflage and its beauty.

There is a lot to learn about reptiles and probably some misconceptions to clear up! You can use our Changing Planet: Disappearing Lizards page and classroom lesson to review reptile basics in your classroom and to learn about how lizards populations are struggling with warming global temperatures.

Enjoy these additional resources and remember, that it's not fair to judge a reptile by its "wrap" - scaly though it may be!

Shorter Days Bring Autumn Colors

Did you know that trees in temperate forest ecosystems sense the onset of shorter days and longer nights in the fall?  This change of seasons triggers the development of a weak zone of tissue at the base of each leaf in deciduous trees.  Stems will eventually snap in the breeze, releasing leaves to the ground.

The bright side of this story is that some leaves may become brilliantly colored before they fall, thanks to their pigments—green chlorophyll, orange carotenoid, and yellow xanthophyll.  Leaf pigments sustain plants by means of photosynthesis throughout spring and summer by capturing visible light energy in the blue, violet, and red wavelengths of the Sun’s electromagnetic spectrum.  This chemical reaction enables plants to grow, flower, and produce seeds by harnessing light energy to transform carbon dioxide and water into sugar, releasing the byproduct, molecular oxygen.

As transport of water and nutrients to the leaves decreases in autumn, chlorophyll production ceases.  The green color fades, and the more stable carotenoid and xanthophyll pigments become visible, delighting our eyes with shows of gold and orange foliage.  In plant species such as maple and sumac, sugars trapped in autumn leaves are turned into anthocyanin pigments.  They appear to set forests ablaze with breathtaking hues of red and purple.  The best autumn colors can be expected when a moist growing season is followed by dry, cool, and sunny fall days with no nighttime frost.

The Many Names of the Full Moon

You've probably heard a Full Moon in the autumn called a "Harvest Moon" or a "Hunter's Moon".  You may even realize that farmers can work late, after sunset, by the light of the Full Harvest Moon; hence the name.  But did you know the Moon has ten other aliases, one for each month of the year?  And that the names of the Full Moon come from Native Americans, the Algonquian tribes of eastern and northern North America?  Learn more at "Full Moon Names".

The small image shown here was taken on September 19, 2013, by NASA and shows the Harvest Moon rising over Washington D.C.

Florence Bascom Paved the Way for Women in the Geosciences!

Imagine searching for rock and mineral samples in remote areas dressed in a long skirt and broad, fancy hat.  Towards the end of the Victorian era when Florence Bascom began her career as a geologist, that was what she wore in the field.  She was hired by the U.S. Geological Survey in 1896, the first woman on the staff, after completing her Ph.D. in geology at Johns Hopkins University, the first woman to do so.

At the time, very few women were allowed to earn advanced degrees in any field.  But today women can be found in every corner of the geosciences – from atmospheric science to volcanology.  This Earth week, spread awareness about women who do geoscience research, and energize girls to consider geoscience as a career.  Who knows, a modern-day Florence Bascom may be sitting in your class!

NOAA's Climate Stewards Education Project Presents Webinar Discussing Ice Core Records and Climate Change

Join us on Monday, October 6, 2014, at 7:30 PM Eastern Time.  Space is limited.  Reserve your Webinar seat now at:  https://www2.gotomeeting.com/register/687917538

After registering you will receive a confirmation email containing information about joining the Webinar.  Our Featured speaker is Dr. Richard Alley, Evan Pugh Professor of Geosciences and Associate of the Earth and Environmental Systems Institute at Pennsylvania State University.  He will be giving our main presentation Bungy Jumping off the Ice-Core Roller Coaster: Ice-Core Records of Global Warming and Abrupt Climate Change.

Dr. Alley will discuss how ice cores provide remarkably accurate records of climate changes locally, regionally and globally.  Ice-core records of ice age cycles contribute to our understanding that CO2 has been “the biggest control knob” of Earth’s overall climate, and thus that if we continue burning fossil fuels and releasing CO2, we will have large impacts on climate.  But, ice-core records also show how changes in ocean circulation have had large, rapid regional impacts.  The existence of such abrupt climate changes contributes to our understanding that, if scientists are wrong about the influence of CO2 on climate, changes are likely to be more damaging than expected rather than less damaging.

Ocean Acidification Resources for Communicators and Educators (SOARCE) Webinars

Citizen Science the Focus of New Earth Science Week Site

Science teachers and students can go online to use a new educational resource of the Earth Science Week website, the "Be a Citizen Scientist" page, which features information and links for recommended "citizen science" programs focusing on Earth science.

Citizen science initiatives invite ordinary citizens to participate in scientific research by making observations and contributing to large data sets. Such projects offer great ways for young people, amateur enthusiasts, and other nonprofessional scientists to become actively involved in the scientific process.

The "Be a Citizen Scientist" page, for example, shines a spotlight on initiatives that invite students and others to participate in large-scale research on earthquakes, coastal erosion, flooding, landslides, and other geoscientific phenomena.

Such activities reinforce the Earth Science Week 2014 theme of "Earth's Connected Systems," emphasizing the interactions of the planet's land, air, water, and life systems. The new page is supported the by the U.S. Geological Survey, which sponsors or has partnerships with many citizen science programs.

International Lead Poisoning Prevention Week (October 19-25, 2014)

Lead poisoning is one of the oldest known environmental hazards, but only in the late 1900's did we begin to understand that even small amounts of exposure still impact our body’s functions.  To date, there is no known safe amount we can be exposed to that won't cause the body harm.  It is estimated that 0.6% of disease, globally, is due to lead exposure.  It is particularly a concern in developing children and is estimated to contribute to 600,000 new cases of intellectual disabilities every year.

Although awareness has risen, the vast majority of exposure is still due to lead-based paint.  Most homes built in the U.S. before 1978 have lead-based paint.  The U.S. Department of Housing and Urban Development (HUD) suggests 24 million homes in the U.S. alone have peeling and chipping lead-based paint.  Here are some steps from the HUD for decreasing risk in your own home and ways you can get involved in Lead Poisoning Prevention Week.

World Water Monitoring Challenge - October 31st Deadline

Living in the Shadow of Mauna Loa - A Silent Summit Belies a Volcano's Forgotten Fury

Earth's largest active volcano, Mauna Loa on Hawaii's Big Island, is taking a nap.  And after 30 years, no one is sure when the sleeping giant will awaken.  Scientists say it's likely to erupt again within the next couple of decades and, when it does, it will be spectacular — and potentially dangerous.

Although Mauna Loa often takes a back seat to the more famous Kilauea, which has been erupting nearly continuously since 1983, history warns us that Mauna Loa's current silence is anomalous.  Meanwhile, more people and more buildings pack into potentially hazardous areas: locations where Mauna Loa's lava has reached in the past and will likely reach again.  Read more about the steps geologists are already taking - such as upgrading their monitoring tools and talking with the public - to prepare for another eruption of Mauna Loa in the September issue of EARTH Magazine.

Virtual Water - Tracking the Unseen Water in Goods and Resources

"Virtual water" was coined in 1993 to help explain why long-predicted water wars driven by water and food security had not occurred among the arid nations of the Middle East and North Africa.  The virtual water notion refers basically to the total amount of freshwater, either from rainfall or irrigation, used in the production of food commodities, including crops and fodder-fed livestock, or other goods and services - agricultural, industrial or otherwise.  Taking root in the late 1990's across a range of disciplines, the concept has since expanded and evolved.

Today, virtual water has been cited by many as a potentially valuable tool for influencing trade and water policies to promote conservation and combat water scarcity.  Trading in virtual water between water-rich and water-poor regions has been suggested as a means to allay water scarcity.  Read more about how the virtual water concept has gained a foothold among a number of governments and multinational businesses in the October issue of EARTH magazine.

AGI Report Details Status of Geoscience Workforce

AGI, the American Geosciences Institute, recently released its latest “Status of the Geoscience Workforce Report,” showing that jobs requiring training in the geosciences continue to be lucrative and in-demand.  Despite increased enrollment and graduation from geoscience programs, data project a shortage of around 135,000 geoscientists by the end of the decade. 

The 2014 report covers the state of the geoscience workforce and education in K-12 schools, universities, and two-year colleges.  The number of graduating geoscience majors who started their degrees at a two-year college has increased, according to report author Carolyn Wilson.

“There is incredible potential for institutions to recruit from the diverse talent pools arising at two-year institutions, and many career opportunities available to students enrolled in geoscience programs, and early-career geoscientists entering the workforce,” Wilson said.  Click here for more information on the report.
