Videos: “Space to Ground” + Other ISS reports – Sept.18.2020

Here is the latest episode in NASA’s Space to Ground weekly report on activities related to the International Space Station:

** Astronaut Jeanette Epps – First Operational Boeing Crew Mission to ISSSpace Snack

NASA has assigned astronaut Jeanette Epps to NASA’s Boeing Starliner-1 mission, the first operational crewed flight of Boeing’s CST-100 Starliner spacecraft on a mission to the International Space Station. Epps will join NASA astronauts Sunita Williams and Josh Cassada for a six-month expedition planned for a launch in 2021 to the orbiting space laboratory. The flight will follow NASA certification after a successful uncrewed Orbital Flight Test-2 and Crew Flight Test with astronauts. The spaceflight will be the first for Epps, who earned a bachelor’s degree in physics in 1992 from LeMoyne College in her hometown of Syracuse, New York. She completed a master’s degree in science in 1994 and a doctorate in aerospace engineering in 2000, both from the University of Maryland, College Park.

** Earth Views from the International Space StationAmericaSpace

The International Space Station’s High Definition Earth Viewing (HDEV) experiment is an external camera platform located on the Columbus module of the space station. In addition to providing beautiful views of Earth, one of the goals of HDEV is to monitor the longevity and quality of its image sensors in the space environment. HDEV operations began April 30, 2014 and only a single bad pixel has been identified. Credit: NASA

** ISS transit of Mars, September 14, 2020Tom Glenn

The International Space Station (ISS) transits Mars, as captured from San Diego, CA on September 14, 2020 at 05:15:47 PDT (12:15:47 UT). This required being positioned exactly on the line shown in the map in the video, to within less than 100m accuracy on the ground. This is complicated by the fact that the ISS orbit is inherently unstable in low Earth orbit, which causes the predicted ground path to change by small amounts leading up to the event. Even at the time of the event, the best prediction is associated with a small amount of error, on the order of one ISS diameter (~100m). At the time of this image, my telescope was sitting directly on the GPS coordinates of the predicted centerline of the transit, but you can see the center of the ISS was ever so slightly below the disk of Mars. However, it was close enough, and part of the solar arrays appear to touch the planetary disk in one frame. Still images at higher quality are available at the following links https://flic.kr/p/2jH5Dnu https://flic.kr/p/2jH6zRa

Here is the latest episode in NASA’s Space to Ground weekly report on activities related to the International Space Station:

** Students Use Ham Radio to Call an Astronaut in SpaceNASA Johnson

On May 15, 2020, Canadian students used ham radio to talk with NASA astronaut Chris Cassidy, currently aboard the International Space Station. Thanks to ham radio operators and the International Space Station program, the students were able to participate from their homes. Learn more about ham radio aboard the space station: https://go.nasa.gov/2DRPAeK Learn more about the research being conducted on station: https://www.nasa.gov/iss-science

** Tropical Storm Laura Viewed From International Space StationNASA Johnson

External cameras on the International Space Station captured views of Tropical Storm Laura from approximately 250 miles above. The station passed directly over the tropical system on Sunday, August 23 prior to the storm making landfall on Cuba. The National Hurricane Center is projecting Laura to strengthen into a hurricane once in the Gulf of Mexico with landfall expected on the Gulf coast later this week.

** Every Spacecraft Which Has Visited The Space StationScott Manley

Over the last 2 decades there have been over 200 spacecraft which have visited the space station, built by many nations and organizations, with different designs. So I thought it might be nice to make a summary of every spacecraft for comparison since we’re getting close to the 20th anniversary and 100th crew to visit the ISS.

** NASA Makes Fifth State of Matter Aboard Space StationNASA Jet Propulsion Laboratory

Solid, liquid, gas, plasma… did you know there’s also a fifth state of matter? Since 2018, NASA’s Cold Atom Lab has been using the microgravity environment on the International Space Station to help chill atoms to almost absolute zero – the coldest temperature matter can reach. At these low temperatures, Cold Atom Lab produces the fifth state of matter, called a Bose-Einstein condensate.

Experiments with this fifth state of matter could lend deeper insight into how our world works on a fundamental level. For example, scientists will be able to measure the very faint tug of gravity that is still present aboard the station, and put Albert Einstein’s theory about this fundamental force to the test. Studies of Bose-Einstein condensates aboard the station could also lead to new technologies, like better tools for navigation and more precise clocks.
