Spotlight On ...

Field Test Sites Needed for July!

We are looking for 12 library and after-school programs to test the latest Explore Module — Mars —Inside and Out! Through hands-on activities, children will examine Mars and Earth features and investigate the processes that formed them, explore the interior of these planets with edible models, and learn why Earth and Mars are so different! Qualifying programs must be willing to run the program twice with different groups of children between the ages 8–13. Each program must have a minimum of 20 participants and is anticipated to require no more than 10 hours of program time. Program format is flexible, but must be completed during the month of July.  Participating program providers will have evaluation forms to complete and may have a follow-up phone conversation. Each of the 12 participating programs will receive $700, chocolate, and the unending appreciation of the Explore Team!

Help us shape the next Explore Module!

If interested, contact Becky Nelson ASAP!
We are working to get programs with a diversity of audiences involved
and will confirm participation by June 10.

Becky Recommends!

As the activity designer for several of the Explore!  modules, I am always on the lookout for great ways  to engage children in Earth and space science. All activities in Becky Recommends! are designed for tight budgets and tight spaces, and are always educational and fun!
Last month’s activity, Sponge Spool Spine, was the third in a series of activities on Health in Space! This month’s activity, Beans in Space, focuses on muscle atrophy, one of the effects of microgravity. A more detailed version of the activity may be is available on the Health in Space website.

Beans in Space

What’s Needed?

The following materials are for one Beans in Space! activity set:

  • 2 opaque non-breakable containers (coffee cans work well)
  • Tape (to seal the containers)
  • 3 cups of beans (for the Earth can)  
  • Paper or foam to stuff inside the Earth can so that the beans don’t rattle
  • Labels for each can
  • Paper to cover the containers (optional)


Who?

Children ages 8–13

How Long?

1 minute per child

Overview

In Beans in Space! children ages 8–13 perform 20 arm curls with cans that simulate the weight of beans on Earth and the weight of the same number of beans in space. They explore what happens to muscles in space that do not have to fight the force of gravity.

 

Preparation

Cartoon of an Astronomer looking through a telescopeAstronomy Afterschool Program
The Beyond Einstein Explorers' Program (BEEP) is an afterschool/summer program designed to introduce basic concepts about astronomy and the Universe beyond the solar system to middle-school students. Developed by the Astrophysics Science Division at NASA Goddard, BEEP has 12 sessions with hands-on activities in each session. The program is now recruiting participants for summer 2007. A two-day training will be held at NASA Goddard on June 13–14.

Exploring Space Lecture
World-class scholars discuss current missions to the distant realm of the gas giants, the icy Kuiper Belt and beyond. This is the last in a series of free lectures that will be held at the National Air and Space Museum in Washington, D.C. It will be webcast live as well as archived for free viewing online. Mark your calendar for the June 14 lecture - New Horizons: Exploring the Solar System's Frontier by Dr. S. Alan Stern.

The National AfterSchool Association is partnering with the National Association of
Elementary School Principals to develop and present the AfterSchool Strand at the NAESP Principals' Summer Leadership Institute July 15-19. The AfterSchool Strand includes such topics as quality program standards and alignment between afterschool activities and the school day.

Mission News and Science

The Brightest Supernova Ever
Modified from SCIENCE@NASA

Artist's illustration of supernova SN 2006 gyThe brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. This explosion was a hundred times more energetic than a typical supernova, from an enormous star 150 times the mass of our Sun.  The observations indicate that the explosions of extremely massive stars in the early universe were a different, more violent type of supernova than those usually observed in the modern universe.

Astronomers think many of the first stars in the Universe were this massive, and this new supernova may thus provide a rare glimpse of how those first generation stars died. The data on the supernova SN 2006gy suggest that spectacular supernovas from the first stars that spew their remains - rather than collapsing to a black hole as theorized - may be more common than previously believed.

NASA Antenna Cuts Mercury to Core, Solves 30 Year Mystery
Modified from JPL News Releases

Diagram showing the interior structure of Mercury.Researchers working with high-precision planetary radars have discovered strong evidence that the planet Mercury has a molten core, changing our view of Mercury’s composition and how Mercury and the other planets in our Solar System first formed. The molten core explains the weak magnetic field around Mercury detected by the Mariner 10 spacecraft in 1974 and 1975.

Among Mariner 10’s discoveries was that Mercury had its own weak magnetic field - about one percent as strong as that found on Earth. This was unexpected — scientists believe that Earth’s magnetic field
is generated by a rotating molten outer core, and Mercury was believed too small to have a molten core. Scientists theorized that Mercury consisted of a silicate mantle surrounding a solid iron core. This iron was considered solid — or so the theory went — because small planets like Mercury cool off rapidly after their formation. If Mercury followed this pattern, then its core should have frozen long ago.

In 2002, scientists began pointing some of our most powerful antennas at Mercury. Using the radar echoes off of Mercury’s surface, scientists calculated Mercury's spin rate to an accuracy of one-thousandth of a percent. With these data the science team was able to detect tiny twists in Mercury's spin as it orbited the Sun. These small variations were double what would be expected for a completely solid body. This finding ruled out a solid core, so the only logical explanation remaining was that the core — or at the very least the outer core — is molten and not forced to rotate along with its shell.

Flyby of Jupiter
Modified from SCIENCE@NASA

Jupiter's "Little Red Spot".NASA has released stunning new images of Jupiter and its moons taken by the New Horizons spacecraft. Views include a movie of a volcanic eruption on Jupiter's moon Io; a nighttime shot of auroras and lava on Io; a color photo of the "Little Red Spot" churning in Jupiter's cloudtops; images of small moons herding dust and boulders through Jupiter's faint rings--and much more.

New Horizons came within 1.4 million miles of Jupiter on Feb. 28 in a gravity assist maneuver designed to trim three years off its travel time to Pluto. For several weeks before and after this closest approach, the probe trained its cameras and sensors on Jupiter and its four largest moons.

A highlight of the flyby was the first close-up color scan of the Little Red Spot.  This storm is about half the size of Jupiter's larger Great Red Spot and about 70 percent of Earth's diameter. It formed in the late 1990s when three smaller storms collided and merged. The combined storm started out white, but began turning red about a year ago. Using New Horizons data, scientists will be able to search for clues about how these great storm systems form and why they change colors.

The Tvashtar volcano and plume on Io.Of Jupiter's four largest moons, the team focused much attention on volcanic Io, the most geologically active body in the solar system. New Horizons' cameras captured pockets of bright, glowing lava scattered across the surface; dozens of small, glowing spots of gas; and several views of a sunlit umbrella-shaped dust plume rising 200 miles into space from the volcano Tvashtar, the best images yet of a giant eruption from the tortured volcanic moon.

The timing and location of the spacecraft's trajectory also allowed it to spy many of the mysterious, circular troughs carved onto the icy moon Europa. Data on the size, depth and distribution of these troughs, discovered by the Jupiter-orbiting Galileo mission, will help scientists determine the thickness of the ice shell that covers Europa's global ocean.
