Hubble to Use Moon as Mirror to See Venus Transit

This mottled landscape showing the impact crater Tycho is among the most violent-looking places on our moon. Astronomers didn’t aim NASA’s Hubble Space Telescope to study Tycho, however. The image was taken in preparation to observe the transit of Venus across the sun’s face on June 5-6.

Hubble cannot look at the sun directly, so astronomers are planning to point the telescope at Earth’s moon, using it as a mirror to capture reflected sunlight and isolate the small fraction of the light that passes through Venus’s atmosphere. Imprinted on that small amount of light are the fingerprints of the planet’s atmospheric makeup.

As the transit of Venus approaches, have your students use transit light curve data gathered by the Kepler mission to calculate the size of planets in other solar systems. To complete this lesson, students determine if these planets are in habitable zones. To gain access to Algebraic Equations: Transit Tracks—Finding Habitable Planets, visit the NES Virtual Campus.

Astronaut Don Pettit and the ISS Transit of Venus

In 1768, when James Cook sailed out of Plymouth harbor to observe the Transit of Venus in Tahiti, the trip was tantamount to a voyage through space. The remote island had just been “discovered” a year earlier, and by all accounts it was as strange and alien to Europeans as the stars themselves. Cook’s pinpoint navigation to Tahiti and his subsequent observations of Venus crossing the South Pacific sun in 1769 have inspired explorers for centuries.

One of those explorers is about to beat Cook at his own game. High above Earth, astronaut Don Pettit is preparing to photograph the June 5th Transit of Venus from space itself.

Partial Eclipse of the Strawberry Moon

On June 4, 2012, there’s going to be a full moon. According to Native American folklore it’s the Strawberry Moon, so-called because the short season for harvesting strawberries comes during the month of June.

This Strawberry’s going to have a bite taken out of it.

At 3:00 a.m. PDT, not long before sunrise on Monday, June 4, the moon passes directly behind our planet. A broad stretch of lunar terrain around the southern crater Tycho will fall under the shadow of Earth, producing the first lunar eclipse of 2012. At maximum eclipse, around 4:04 a.m. PDT, 37% of the moon’s surface will be in the dark.

NASA Now: Model Aircraft

NASA NowIn this episode of NASA Now, Sam James explains why NASA engineers build model aircraft. James talks about how models are tested in wind tunnels and why it’s important to create models that are proportional to full-scale aircraft. He discusses why models are an inexpensive alternative to full-scale aircraft during the redesigning stage of the engineering design process.


This program is available on the Virtual Campus beginning May 30.

My American Landscape Contest: A Space Chronicle of Change

To celebrate the fortieth anniversary of the United States’ Landsat Earth-observing program — which first rocketed into space on July 23, 1972 — NASA and the U.S. Geological Survey are giving something special to a few members of the American public. We will create customized Landsat chronicles of changing local landscapes for six U.S. citizens who enter the “American Landscape” contest.

To enter, all you have to do is send an e-mail and tell us about the local landscape changes you are interested in where you live and what you hope to learn about them from Landsat’s four-decades of observations from space.

Deadline for submissions is Wednesday, June 6. Contest winners will be announced live on NASA Television at a Landsat 40th anniversary press briefing in Washington on Monday, July 23.

June 5 Transit of Venus

On June 5, 2012, Venus will transit the face of the sun in an event of both historical and observational importance. The best places to watch are in the south Pacific, but travel is not required. The event will also be visible around sunset from the USA. The next transit of Venus won’t happen again until December 2117, 105 years from now. (Note: The pattern is + 8 + 105.5 + 8 + 121.5 +…)

NES Re-enrollment for 2013 School Year

NASA Explorer Schools
NASA Explorer Schools has officially kicked off enrollment for the 2012-2013 school year. Current participants can re-enroll for the upcoming year to ensure continued access to NES’s engaging and exciting classroom materials. 

Re-enrollment is simple and painless.  When you next log onto the Virtual Campus, you will receive a prompt to fill out a brief re-enrollment form where you can update your personal, school and classroom information. Fill out the form, click “submit”, and you’ll have full access to NES’ exciting and engaging educational resources and opportunities for the upcoming school year. The information you provide on the form can always be updated at any time through your profile.


Anyone enrolling for the first time in the NES project after May 17 will automatically be enrolled for the 2013 school year.
If you have any questions, contact the NES Help Desk.

Solar Eclipse in the USA

On Sunday, May 20th, the Moon will pass in front of the sun, transforming sunbeams across the Pacific side of Earth into fat crescents and thin rings of light.

In the United States, the eclipse begins around 5:30 pm PDT. For the next two hours, a moon-shaped portion of the sun will go into hiding. Greatest coverage occurs around 6:30 pm PDT.
