Videos: “Space to Ground” & other space habitat reports – July.3.2023

July 3, 2023 TopSpacer

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

** Expedition 69 SpaceX Dragon CRS-28 Cargo Ship Departs International Space Station June 29, 2023 – NASA Video

Loaded with scientific experiments and supplies, the unpiloted SpaceX Dragon undocked from the International Space Station June 29, completing a three-week-long mission to the outpost for the company’s 28th commercial resupply services mission for NASA. The SpaceX spacecraft undocked from the zenith port of the Harmony module, headed for a splashdown off the coast of Florida June 30 to complete its flight that delivered several tons of experiments and hardware to the station.

The SpaceX Dragon CRS-28 cargo ship undocked from the International Space Station on June 29, 2023. Full Story: https://www.space.com/spacex-dragon-c…

It [made] a parachute-aided splashdown off the coast of Jacksonville, Florida on Friday (June 30) at around 10:30 a.m. EDT (1430 GMT), NASA officials said

** Expedition 69 Space Station Crew Talks with WBTS-TV Boston, AccuWeather June 29, 2023 – NASA Video

Aboard the International Space Station, Expedition 69 Flight Engineers Woody Hoburg and Steve Bowen of NASA discussed life and work aboard the orbital outpost during an in-flight interview June 29 with WBTS-TV (NBC, Boston) and AccuWeather. Hoburg and Bowen are in the midst of a long-duration mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions. Such research benefits people on Earth and lays the groundwork for future human exploration through the agency’s Artemis missions, which will send astronauts to the Moon to prepare for future expeditions to Mars.

** What is MMOD Shielding? – Gravitics Inc

Gravitics MMOD Shielding tests were a success. In this video you can learn more about what goes into building the outer shell of a spacecraft, complete with solar cells, electrical harnessing, heat radiators, and protection against debris and radiation.

** China’s Space Station Complex to Adopt New Configurations: Agency – CCTV Video News Agency

China’s space station complex will adopt other new configurations beyond the current “three modules and three spacecraft” configuration in the coming months, according to the China Manned Space Agency (CMSA).

** Live Video from the International Space Station (Official NASA Stream) – NASA

Watch live video from the International Space Station, including inside views when the crew aboard the space station is on duty. Views of Earth are also streamed from an external camera located outside of the space station. During periods of signal loss due to handover between communications satellites, a blue screen is displayed.

The space station orbits Earth about 250 miles (425 kilometers) above the surface. An international partnership of five space agencies from 15 countries operates the station, and it has been continuously occupied since November 2000. It’s a microgravity laboratory where science, research, and human innovation make way for new technologies and research breakthroughs not possible on Earth. More: https://go.nasa.gov/3CkVtC8

Did you know you can spot the station without a telescope? It looks like a fast-moving star, but you have to know when to look up. Sign up for text messages or email alerts to let you know when (and where) to spot the station and wave to the crew: https://spotthestation.nasa.gov

** What’s Up: July 2023 Skywatching Tips from NASA – NASA JPL

What are some skywatching highlights in July 2023?

Mars and Venus start the month close together, but part ways and head lower as July goes on. Mars appears very near Regulus in Leo on the 9th and 10th. Saturn and Jupiter rule the night, along with bright star Fomalhaut. And July is prime time for viewing the Milky Way core from dark sky locations.

0:00 Intro
0:12 Mars & Venus in the evening
0:31 Mars close to Regulus
1:07 Saturn & Jupiter in the morning
1:49 Fomalhaut’s debris disk
