The Last of the Great Observatories: Spitzer And the Era of Faster, Better, Cheaper at NASA
The Spitzer Space Observatory is the last of the four “Great Observatories”, which also include the Hubble Space Telescope, the Chandra X-ray Observatory, and the Compton Gamma Ray Observatory. George Rieke played a key role in Spitzer and now relates the story of how that observatory was built and launched into space. Up to its official start and even afterward, Spitzer was significant not merely in terms of its scientific value but because it stood at the center of major changes in space science policy and politics.

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. The following activity is the second in a series of activities on the Moon. All activities in Becky Recommends! are designed for tight budgets and tight spaces, and are always educational and fun!
I think edible activities rock, and this fun activity is both educational and delicious! What better way to familiarize children with lunar phases or reinforce prior learning?!
Materials for each child:
8 Oreo® cookies (4 for younger children)
½ sheet of poster board
A plastic spoon and/or a plastic knife
Halve and scrape Oreo® cookies to illustrate Moon phases. Then arrange cookies on the poster in linear fashion beginning with the New Moon and ending with the Waning Crescent Moon.You may be familiar with other activities that place the phases in a circular formation. We feel this could, however, confuse young children if they attempt to conceptualize the location of the Sun or Earth in relation to the Moon’s orbit. We, therefore, recommend that first children simply learn to correctly match the names with the appearances of each phase. For children younger than 8, you may want to model only 4 Moon phases, i.e. New Moon (completely dark), Crescent Moon, first Quarter (or Half) Moon, and Full Moon. Older children should be able to model all 8 phases, as shown below:
New Evidence Water Still Flows on Mars
Modified from Jet Propulsion Laboratory News Releases
NASA photographs have revealed bright new deposits seen in two gullies on Mars, suggesting that water carried sediment through them sometime during the past seven years. Liquid water is considered necessary for life, so the new findings heighten intrigue about the potential for microbial life on Mars.The Mars Orbiter Camera on NASA's Mars Global Surveyor provided the new evidence of the deposits in images taken in 2004 and 2005.
The atmosphere of Mars is so thin and the temperature so cold that liquid water quickly evaporates or freezes. Scientists propose that water could exist in an underground source and break out through the walls of a crater, carrying debris downslope before totally freezing. Mars Global Surveyor has discovered tens of thousands of gullies on slopes inside craters and other depressions on Mars. Scientists first reported the discovery of the gullies in 2000. To look for changes that might indicate present-day flow of water, they repeatedly imaged hundreds of the sites. The two fresh deposits are each several hundred yards long. The light tone of the deposits could be from surface frost or a salty crust. This is the first evidence of newly deposited material apparently carried by fluids after earlier imaging of the same gullies.
Mars Global Surveyor began orbiting Mars in 1997. The spacecraft is responsible for many important discoveries. NASA has not heard from the spacecraft since early November. Attempts to contact it continue. Its unprecedented longevity has allowed monitoring Mars for over several years past its projected lifetime.
Early Bacteria Protected from Poisonous Oxygen
Modified from CALTECH Media Relations
Two and a half billion years ago, the process known as photosynthesis suddenly began, releasing molecular oxygen into Earth's atmosphere and causing one of the largest environmental changes in the history of our planet. The organisms assumed responsible were the cyanobacteria, which evolved the ability to turn water, carbon dioxide, and sunlight into oxygen and sugar, and are still around today as the blue-green algae and the chloroplasts in all green plants. But researchers have long been puzzled as to how the cyanobacteria could make all that oxygen without poisoning themselves. To avoid their DNA getting wrecked by a hydroxyl radical that naturally occurs in the production of oxygen, the cyanobacteria would have had to evolve protective enzymes. But how could natural selection have led the cyanobacteria to evolve these enzymes if the need for them didn't even exist yet?
Now, two groups of researchers at the California Institute of Technology offer an explanation of how cyanobacteria could have avoided this seemingly hopeless contradiction. Reporting in the December 12 Proceedings of the National Academy of Sciences (PNAS), the groups demonstrate that ultraviolet light striking the surface of glacial ice can lead to the accumulation of frozen oxidants and the eventual release of molecular oxygen into the oceans and atmosphere. This trickle of poison could then drive the evolution of oxygen-protecting enzymes in a variety of microbes, including the cyanobacteria. According to Danie Liang, a serious freeze-over known as the Makganyene Snowball Earth occurred 2.3 billion years ago, at roughly the time cyanobacteria evolved their oxygen-producing capabilities. During the Snowball Earth episode, enough peroxide could have been stored to produce nearly as much oxygen as is in the atmosphere now. Cyanobacteria would have evolved enzymes to protect themselves from the oxygen, which then would have been used to protect them when they began to photosynthesize and release additional oxygen into the oceans and atmosphere.
Evidence that Dark Energy Was Present in Early Universe
Modified from NASA News
Scientists using NASA's Hubble Space Telescope have discovered that dark energy is not new, but rather has been present for most of the universe's history. Dark energy is a mysterious repulsive force that causes the universe to expand at an increasing rate. Investigators used Hubble to find that dark energy was already boosting the expansion rate of the universe as long as nine billion years ago. This data will allow scientists to begin ruling out some competing explanations for dark energy that predict that the strength of dark energy changes over time.
To study the behavior of dark energy of long ago, Hubble had to peer far across the universe and back into time to detect supernovae. Supernovae can be used to trace the universe's expansion. Over the past eight years astrophysicists have been trying to uncover two of dark energy's most fundamental properties: its strength and its permanence. These new observations reveal that dark energy was present and obstructing the gravitational pull of the matter in the universe even before it began to win this cosmic "tug of war." Previous Hubble observations of the most distant supernovae known revealed that the early universe was dominated by matter whose gravity was slowing down the universe's expansion rate. The observations also confirmed that the expansion rate of the cosmos began speeding up about five to six billion years ago.
