Although the space between the sun and Earth appears empty to human eyes, it is actually full of particles and energy from the constant flow of solar wind emitted by the sun. Heliophysics, the study of the sun and its influence on the planets and space surrounding them, has important implications for our day-to-day lives. Credit: NASA’s Goddard Space Flight Center Observing plasma blasts and solar flares can help us better understand and mitigate the impact of such eruptions on technology in space.
Sunspots, coronal holes and coronal loops, for example, can reveal how those magnetic fields dance through the Sun and its atmosphere. The stamps highlight different features on the Sun that help scientists learn about how our star works and how its constantly churning magnetic fields create the solar activity we see. Each black-and-white image is colorized to the bright hues seen here. The Solar Dynamics Observatory lets us see the Sun in wavelengths of ultraviolet light that would otherwise be invisible to our eyes. The Sun is the only star that humans are able to observe in great detail, making it a vital source of information about the universe. These images come from NASA’s Solar Dynamics Observatory, a spacecraft launched in February 2010 to keep a constant watch on the Sun. Postal Service illuminates the light and warmth of our nearest star by highlighting these stunning images of the Sun on stamps. One of the stamps highlights sunspots, two feature images of coronal holes, two show coronal loops, two depict plasma blasts, one is a view of an active sun that emphasizes its magnetic fields, and two show different views of a solar flare. Instead, each image is colorized by NASA according to different wavelengths that reveal or highlight specific features of the sun’s activity. The striking colors in these images do not represent the actual colors of the sun as perceived by human eyesight. Inside they found Ham in good spirits, and he excitedly accepted an apple and half an orange.Printed with a foil treatment that adds a glimmer to the stamps, the images on these stamps come from NASA’s Solar Dynamics Observatory, a spacecraft launched in February 2010 to keep a constant watch on the sun from geosynchronous orbit above Earth. It landed out of sight of the recovery forces, but they found the ship within a half hour and airlifted it to the nearby USS Donner. Then 16 minutes and 39 seconds after the launch, the craft splashed down in the Atlantic. The rocket also reached a higher speed than expected and Ham was weightless for 6.6 minutes instead of the expected 4.9 minutes.ĭespite the issues that arose, Ham successfully went about completing his tasks, which included pushing levers about 50 times. There were also cameras onboard that showed how Ham reacted to the weightlessness and also revealed a surprising amount of dust floating in the air. Additionally, the cabin pressure dropped due to an unexpected issue, but Ham was safe in his space suit. The rocket ended up on a high flight angle, which would lead to it missing its landing area by 130 miles. The launch was delayed for nearly four hours due to a few minor issues, but at 4:55 pm, the MR-2 lifted off. The craft had six new systems that weren’t on prior flights, including environmental controls, attitude stabilization, live retrorockets, voice communications, a closed loop abort sensing system, and a pneumatic landing bag. At 12:53 pm on January 31, 1961, Ham was placed into the spacecraft.
