June 24, 2015: Aurora in green and red from International Space Station. NASA Astronaut Scott Kelly captured this photo of an aurora from the International Space Station on June 23, 2015. The dancing lights of the aurora provide spectacular views on the ground, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections or CMEs.

June 18, 2015: On June 18, 1983, Sally Ride became the first American woman to fly in space when the space shuttle Challenger launched on mission STS-7 from Pad 39A at NASA's Kennedy Space Center in Florida. The STS-7 crew consisted of astronauts Robert Crippen, commander, the first two-time space shuttle astronaut; Frederick H. Hauck, pilot; and three mission specialists—Ride, John M. Fabian and Norman E. Thagard.
This high-angle view of the shuttle liftoff, showing a lengthy stretch of Florida Atlantic coastline and a number of large cumulus clouds, was photographed with a handheld 70mm camera by astronaut John W. Young, who piloted the Shuttle Training Aircraft (STA) for weather monitoring at launch and landing sites for STS missions.
One of Sally Ride's jobs was to call out "Roll program" seven seconds after launch. "I'll guarantee that those were the hardest words I ever had to get out of my mouth," she said later.

This new NASA/ESA Hubble Space Telescope image shows four of the seven members of galaxy group HCG 16. This quartet is composed of (from left to right) NGC 839, NGC 838, NGC 835, and NGC 833—four of the seven galaxies that make up the entire group. They shine brightly with their glowing golden centres and wispy tails of gas, set against a background dotted with much more distant galaxies.
This new image uses observations from Hubble's Wide Field Planetary Camera 2 combined with data from the ESO Multi-Mode Instrument, installed on the European Southern Observatory's New Technology Telescope in Chile.

- California Institute of TechnologyStaff Scientist, 2012 - presentI'm a principle mission scientist on a NASA Small Explorer mission, the Nuclear Spectroscopic Telescope ARray (NuSTAR), the world's first focusing hard X-ray telescope. I "do science" (I mostly study supernova remnants like Cassiopeia A) now that NuSTAR is up in space, but I also help to develop and maintain the software down here on the ground that turns the bits and bytes coming down from NuSTAR into pictures and spectra.
