SWOT: Earth Science Satellite Will Help Communities Plan for a Better Future:-
A new Earth science mission, led by NASA and the French space agency Centre National d’Études Spatiales (CNES), will help communities plan for a better future by surveying the planet’s salt and freshwater bodies. The Surface Water and Ocean Topography (SWOT) mission will measure the height of water in lakes, rivers, reservoirs, and the oceans. As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough. SWOT data will be used to improve flood forecasts and monitor drought conditions, providing essential information to water management agencies, civil engineers, universities, the U.S. Department of Defense, disaster preparedness agencies, and others who need to track water in their local areas. In this video, examples of how SWOT data will be used in these communities are shared by a National Weather Service representative in Oregon, an Alaska Department of Transportation engineer, researchers from the University of Oregon and University of North Carolina, a NASA Jet Propulsion Laboratory scientist working with the Department of Defense, and a JPL scientist working with the Louisiana Coastal Protection and Restoration Agency. :30 - Flood Watches & Warnings - Portland, Oregon 1:08 - Water Management - Fern Ridge Lake, Oregon 2:05 - Protecting Infrastructure - Alaska 2:54 - National Security - Department of Defense 3:24 - Coastal Protection - Mississippi River Delta SWOT is expected to launch from Vandenberg Space Force Base in California in December 2022. The mission is a collaboration between NASA and CNES, with contributions from the Canadian Space Agency and UK Space Agency. JPL, which is managed for NASA by Caltech in Pasadena, California, leads the U.S. component of the project.

133 Days on the Sun
chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 133-day time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme-ultraviolet wavelength that shows the Sun’s outermost atmospheric layer: the corona. Compiling images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes as magnetic fields snap together in a process called magnetic reconnection. While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.

In this image from Sept. 5, 1983, Guion “Guy” Bluford checks out the sample pump on the continuous flow electrophoresis system (CFES) experiment in the middeck of the Earth-orbiting space shuttle Challenger.
Forty years ago today, he launched from NASA’s Kennedy Space Center in Florida, becoming the first African American to fly in space. Bluford was a member of NASA's "Thirty-Five New Guys" – the 1978 astronaut class, which had the first African American, the first Asian American, and the first women astronauts.
During the STS-8 mission, the crew deployed the Indian National Satellite INSAT-1B, operated the Canadian-built Remote Manipulator System with the Payload Flight Test Article, operated the CFES, conducted medical measurements to understand biophysiological effects of spaceflight, and activated four “Getaway Special” canisters. STS-8 completed 98 orbits of the Earth in 145 hours before landing at Edwards Air Force Base, California, on Sept. 5, 1983.

Studying the Wind with Weather Balloons
Rocky Garcia and Wesley James prepare a weather balloon to collect wind data at NASA’s Armstrong Flight Research Center in Edwards, California, on July 20, 2023. Researchers measured wind at altitudes below 2,000 feet using drones, sensors, weather balloons, and other technology during the Advanced Exploration of Reliable Operation at Low Altitudes: Meteorology, Simulation and Technology campaign. This information could fill knowledge gaps to resolve wind and weather unknowns that could hinder Advanced Air Mobility flights and to improve weather forecasts.

Crew-7 Lifts Off
At 3:27 a.m. EDT on Saturday, Aug. 26, NASA’s SpaceX Crew-7 crew members launched from NASA's Kennedy Space Center in Florida. A SpaceX Falcon 9 rocket carried NASA astronaut Jasmin Moghbeli, European Space Agency astronaut Andreas Mogensen, Japan Aerospace Exploration Agency astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov aboard SpaceX’s Dragon spacecraft. They docked to the International Space Station and joined the current space station crew on Sunday, Aug. 27.
While on the orbiting laboratory, Crew-7 will conduct new scientific research to benefit humanity on Earth and prepare for human exploration beyond low Earth orbit, including the collection of microbial samples from the exterior of the space station, the first study of human response to different spaceflight durations, and an investigation of the physiological aspects of astronauts' sleep.
Learn more about station activities by following the space station blog.

Hubble Sees a Sparkling Neighbor Galaxy
The galaxy ESO 300-16 looms over this image from the NASA/ESA Hubble Space Telescope. This galaxy, which lies 28.7 million light-years from Earth in the constellation Eridanus, is a ghostly assemblage of stars which resembles a sparkling cloud. Other distant galaxies and foreground stars complete this astronomical portrait, which was captured by the Advanced Camera for Surveys.
This observation is one of a series which aims to get to know our galactic neighbors. Hubble has observed around three quarters of known galaxies within about 10 megaparsecs of Earth in enough detail to resolve their brightest stars and establish distances to these galaxies. A team of astronomers proposed using small gaps in Hubble’s observing schedule to acquaint ourselves with the remaining quarter of these nearby galaxies.
The megaparsec – meaning one million parsecs – is a unit used by astronomers to chart the mind-bogglingly large distances involved in astronomy. The motion of Earth around the Sun means that stars appear to slightly shift against very distant stars over the course of a year. This small shift is referred to as parallax and is measured in angular units: degrees, minutes, and seconds. One parsec is equivalent to the distance creating a parallax of one-arcsecond and is equivalent to 3.26 light-years or 30.9 trillion kilometers (19.2 trillion miles). The closest star to the Sun is Proxima Centauri, which lies 1.3 parsecs away.
