Whipple shield used on NASA's Stardust probe. The Whipple shield or Whipple bumper, invented by Fred Whipple, [1] is a type of spaced armor shielding to protect crewed and uncrewed spacecraft from hypervelocity impact / collisions with micrometeoroids and orbital debris whose velocities generally range between 3 and 18 kilometres per second (1.9 and 11.2 mi/s).
The sunshield component attaches to the main spacecraft, and its booms expand outward spreading out the heat shield and separating the layers. [24] During launch the shield is folded up; later, when it is in space, it is carefully unfurled. [24] When the sunshield is fully spread open, it is 14.6 meters (48 ft) wide by 21.1 meters (69 ft) long ...
First image, color images and movie of Earth from space taken by a person, by cosmonaut Gherman Titov – the first photographer from space. [25] [26] 1963 KH-7 Gambit: First high-resolution (sub-meter spatial resolution) satellite photography (classified).

Images were posted online [34] of the two SpaceX-built Space Development Agency Tranche 0 Flight 1 Tracking Layer infrared imaging satellites that launched on 2 April 2023. [35] After the launch of Starlink Group 7-16 , only 20 of a batch of 22 starlink satellites were catalogued, and the remaining two were later designated as USA-350 and USA-351.
Fred Lawrence Whipple (November 5, 1906 – August 30, 2004) was an American astronomer, who worked at the Harvard College Observatory for more than 70 years. Among his achievements were asteroid and comet discoveries, the "dirty snowball" hypothesis of comets, and the invention of the Whipple shield.

As the Impactor neared the comet's surface, this camera took high-resolution pictures of the nucleus (as good as 0.2 meters per pixel [7.9 in/px]) that were transmitted in real-time to the Flyby spacecraft before it and the Impactor were destroyed. The final image taken by the Impactor was snapped only 3.7 seconds before impact.
On July 9, 1947, the front page of The Arizona Republic featured Rhodes's photographs under the headline "Mystery 'Whatsis' Photographed over Phoenix". The newspaper characterized the object depicted in the photographs as "the shape of a heel of a shoe, with a small hole in the center".
