Roman's Sunshade
NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s deployable aperture cover — a visor-like sunshade that will help prevent unwanted light from entering the telescope — to the outer barrel assembly, another structure designed to shield the telescope from stray light.

Earth Information Center
For more than 50 years, NASA satellites have provided data on Earth's land, water, air, temperature, and climate. NASA's Earth Information Center allows visitors to see how our planet is changing in six key areas: sea level rise and coastal impacts, health and air quality, wildfires, greenhouse gases, sustainable energy, and agriculture.

A Rainbow-colored “Feather” in the Martian Sky
NASA’s Curiosity Mars rover captured this feather-shaped iridescent cloud just after sunset on Jan. 27, 2023, the 3,724th Martian day, or sol, of the mission. Studying the colors in iridescent clouds tells scientists something about particle size within the clouds and how they grow over time. These clouds were captured as part of a follow-on imaging campaign to study noctilucent, or “night-shining” clouds, which started in 2021. This scene made up of 28 individual images captured by the rover’s Mast Camera, or Mastcam.
