Examples

  • An intricately designed opening in the starshade would theoretically allow a space-based telescope some thirty-five thousand miles away to peek through and see only the tiny planets and, with an attached spectroscope, learn about its component parts.

  • The telescope would be 35,000 to 50,000 miles away from the starshade, but its aperture would be shaded by the distant barrier petal.

    First Contact

  • As proposed, the starshade would be launched wrapped tight and then would be opened like a travel umbrella using newly declassified technology at its outer-space destination to a size of 170 or even 250 feet in diameter.

  • Though a starshade could significantly complicate JWST's mission, JWST's project scientist,

  • Cash's starshade would resemble a many-petaled sunflower-if sunflowers were matte-black and about half a football field in diameter.

  • Polidan's team has built a scale model of Cash's starshade and tested its light-suppression capabilities in a long vacuum chamber, but most of the work remains theoretical, locked inside relatively inexpensive computer simulations.

  • Cash has spent the last five years designing a starshade that could augment JWST.

  • Two support engineers inspect the starshade prototype testbed at Northrop Grumman's facilities in Redondo Beach, California.

  • Cash has submitted his starshade concept to the committee; other researchers, notably David Spergel and Jeremy Kasdin at Princeton University, are promoting a competing starshade-related proposal.

    SEEDMAGAZINE.COM

  • Kasdin says his team agrees with Cash's about the basic concept of an external occulter, but points out that trying to integrate a starshade into JWST's established program could introduce unnecessary risks: JWST's launch date could slip, pushing up costs on the starshade, and the telescope simply isn't optimized to work with a starshade or to image planets.
