An engineer at NASA's Jet Propulsion Laboratory is shown here with the fast steering mirror, a component of the Coronagraph Instrument on NASA's Nancy Grace Roman Space Telescope. The mirror can make small movements that correct for slight wobbling of the observatory. The incoming image needs to be perfectly sharp in order for the instrument to suppress light from a star while allowing the light from planets orbiting it to pass through. Although the technologies differ, it's analogous to image stabilization in digital cameras, in which the camera lens moves to counteract the shake of your hands and keep the image sharp. The Roman Coronagraph Instrument was designed and is being built at NASA's Jet Propulsion Laboratory, which manages the…
This is one of the last images ever taken by NASAs InSight Mars lander. Captured on Dec. 11, 2022, the 1,436th Martian day, or sol, of the mission, it shows InSights seismometer on the Red Planets surface.
A disk of hot gas swirls around a black hole in this illustration. The stream of gas is what remains of a star that was pulled apart by the black hole. A cloud of hot plasma above the black hole is known as a corona.
NASAs UAVSAR airborne radar instrument imaged Hawaiis Mauna Loa volcano during three flyovers on Dec. 7, 8, and 10. This image captures lava flow thickness, which is one measure of the size of an eruption.
This image from NASAs Mars Odyssey shows an unnamed channel located in Claritas Fossae. The channel flows from the highland of the fossae down into Icaria Planum.
NASAs Perseverance Mars rover used its Mastcam-Z camera to take this image of the location where three of its 10 sample tubes will be deposited.
This map shows where NASAs Perseverance Mars rover will be dropping 10 samples that a future mission could pick up. The orange circles represent areas where a Sample Recovery Helicopter could safely operate to acquire the sample tubes.
