NASA’s Starshade technology to aid observations of far off Planets

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says the feat of staying highly synchronized while airborne can be appreciated by anyone who’s ever seen aircraft engaged in formation flying. In work sponsored by NASA’s Exoplanet Exploration Program (ExEP), engineers at the Jet Propulsion Laboratory in Pasadena, California, are taking formation flying to a new extreme.

Their work marks an important milestone within a larger program to test the feasibility of a technology called a starshade. Although starshades have never flown in space, they hold the potential to enable groundbreaking observations of planets beyond our solar system, including pictures of planets as small as Earth.

Origami inspires NASA Engineers to unique spacecraft designs

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – An ancient art form has taken on new shape at NASA’s Jet Propulsion Laboratory in Pasadena, California.

Origami, the Japanese tradition of paper-folding, has inspired a number of unique spacecraft designs here. It’s little wonder that it fascinates NASA engineers: origami can seem deceptively simple, hiding complex math within its creases.

Besides aesthetic beauty, it addresses a persistent problem faced by JPL engineers: how do you pack the greatest amount of spacecraft into the smallest volume possible?

NASA scientists research ways to discover habitable planets

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists are getting closer to finding worlds that resemble our own “blue marble” of a planet. NASA’s Kepler mission alone has confirmed more than 1,000 planets outside our solar system — a handful of which are a bit bigger than Earth and orbit in the habitable zones of their stars, where liquid water might exist.

Some astronomers think the discovery of Earth’s true analogs may be around the corner. What are the next steps to search for life on these potentially habitable worlds?

This illustration shows the prototype starshade, a giant structure designed to block the glare of stars so that future space telescopes can take pictures of planets.

New Spacecraft being design by NASA may one day take images of Earth like Planets

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars. The prototype deployable structure, called a starshade, is being developed by NASA’s Jet Propulsion Laboratory in Pasadena, CA.

The hunt is on for planets that resemble Earth in size, composition and temperature. Rocky planets with just the right temperature for liquid water — not too hot, not too cold — could be possible abodes for life outside our solar system.
