NASA’s Voyager Spacecrafts broke new ground during 40 years exploration

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Few missions can match the achievements of NASA’s groundbreaking Voyager 1 and 2 spacecraft during their 40 years of exploration. Here’s a short list of their major accomplishments to date. The Voyager spacecrafts made a lot of planetary firsts

Launched in 1977, the Voyagers delivered many surprises and discoveries from their encounters with the gas giants of the outer solar system: Jupiter, Saturn, Uranus and Neptune.

NASA’s Voyager Spacecrafts continue exploration after 40 Years

 

Written by Elizabeth Landau / Jia-Rui Cook
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Humanity’s farthest and longest-lived spacecraft, Voyager 1 and 2, achieve 40 years of operation and exploration this August and September. Despite their vast distance, they continue to communicate with NASA daily, still probing the final frontier.

Their story has not only impacted generations of current and future scientists and engineers, but also Earth’s culture, including film, art and music. Each spacecraft carries a Golden Record of Earth sounds, pictures and messages. Since the spacecraft could last billions of years, these circular time capsules could one day be the only traces of human civilization.

NASA’s Eclipse Balloon Project to simulate life’s ability to survive beyond Earth

 

Written by Andrew Good
NASA’ Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Steps forward in the search for life beyond Earth can be as simple as sending a balloon into the sky. In one of the most unique and extensive eclipse observation campaigns ever attempted, NASA is collaborating with student teams across the U.S. to do just that.

A larger initiative, NASA’s Eclipse Balloon Project, led by Angela Des Jardins of Montana State University, is sending more than 50 high-altitude balloons launched by student teams across the U.S. to livestream aerial footage of the August 21st, 2017, total solar eclipse from the edge of space to NASA’s website.

NASA to use Asteroid Flyby to test Planetary Defense Network

 

Written by Laurie Cantillo / Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA scientists are excited about the upcoming close flyby of a small asteroid and plan to use its upcoming October close approach to Earth as an opportunity not only for science, but to test NASA’s network of observatories and scientists who work with planetary defense.

The target of all this attention is asteroid 2012 TC4 — a small asteroid estimated to be between 30 and 100 feet (10 and 30 meters) in size. On October 12th, TC4 will safely fly past Earth. Even though scientists cannot yet predict exactly how close it will approach, they are certain it will come no closer than 4,200 miles (6,800 kilometers) from the surface of Earth. The asteroid has been out of range of telescopes since 2012.

NASA study reveals why Clouds sometimes produce a Drizzle

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A new NASA study shows that updrafts are more important than previously understood in determining what makes clouds produce drizzle instead of full-sized raindrops, overturning a common assumption.

The study offers a pathway for improving accuracy in weather and climate models’ treatments of rainfall — recognized as one of the greater challenges in improving short term weather forecasts and long-term climate projections.

The research by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California; UCLA; and the University of Tokyo found that low-lying clouds over the ocean produce more drizzle droplets than the same type of cloud over land. The results are published online in the Quarterly Journal of the Royal Meteorological Society.

NASA reports ESA’s LISA Pathfinder Spacecraft powered down

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – With the push of a button, final commands for the European Space Agency’s LISA Pathfinder mission were beamed to space on July 18th, 2017, a final goodbye before the spacecraft was powered down.

LISA Pathfinder had been directed into a parking orbit in April, keeping it out of Earth’s way. The final action this week switches it off completely after a successful 16 months of science measurements.

While some spacecraft are flashy, never sitting still as they zip across the solar system, LISA Pathfinder was as steady as they come — literally.

NASA says the Moon is Front and Center During a Total Solar Eclipse

 

Written by Elizabeth Zubritsky
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – In the lead-up to a total solar eclipse, most of the attention is on the sun, but Earth’s moon also has a starring role.

“A total eclipse is a dance with three partners: the moon, the sun and Earth,” said Richard Vondrak, a lunar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It can only happen when there is an exquisite alignment of the moon and the sun in our sky.”

During this type of eclipse, the moon completely hides the face of the sun for a few minutes, offering a rare opportunity to glimpse the pearly white halo of the solar corona, or faint outer atmosphere.
