Space X Docks with International Space Station Live on YouTube
While the 4th quarter ran down on Monday Night Football, I was consumed by YouTube's live feed of Space X's Dragon docking with the International Space Station. Incredibly, NASA supplied a multi-camera live feed of the entire operation.
It was amazing. to watch!
NASA's SpaceX Crew-1 Mission on the “Resilience” Crew Dragon is carrying Mike Hopkins, Victor Glover, Shannon Walker, and Soichi Noguchi, to the International Space Station.
The docking was scheduled for approximately 11:00 p.m., about 28 hours from the time they launched from Kennedy Space Center. At 10:50 p.m. ET, the Space X Dragon crew decided to delay docking by six minutes because the sun was setting, causing distracting shadows making visibility difficult. The crew was waiting for the sun to completely set, allowing for night vision technology to accurately dock with the station. The space station circles Earth every 45 minutes so the space station gets a sunrise or sunset every 45 minutes. At the time of docking, the sun was beginning to set. Both the Dragon and the International Space Station were traveling approximately 17,500 miles an hour above Earth. The crew was not performing the docking mission, as the Dragon was being flown via auto-pilot (autonomous).
The docking occurred at 11:01 p.m. ET about 252 statute miles over Idaho. They first made what is called a "soft capture" which allows the Dragon to connect with the docking mechanism, which is followed by a "hard capture" which secures the Dragon with hooks for an "air tight" fit with the International Space Station. It will take about an hour for the hatch to open, allowing the passengers to enter the space station. A welcoming ceremony is scheduled for about 1:40 a.m.. A spacewalk is scheduled for Wednesday.
Once the astronauts enter the space station, it will be like walking into a house the size of a six-bedroom house. It has six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window, according to NASA.
NASA streams live programming from the space station regularly from their website. I have to say, it's amazing how much you can see just by logging on to the NASA website. It's also pretty amazing to see how 7 people from different countries can all live in one place and work together with one common purpose. It would be nice if we could do that in Earth.
Interesting Facts About the International Space Station (according to NASA.gov)
- 241 individuals from 19 countries have visited the International Space Station
- The space station has been continuously occupied since November 2000
- An international crew of six people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes.
- In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets
- Peggy Whitson set the record for spending the most total time living and working in space at 665 days on Sept. 2, 2017
- The acre of solar panels that power the station means sometimes you can look up in the sky at dawn or dusk and see the spaceship flying over your home, even if you live in a big city. Find sighting opportunities at http://spotthestation.nasa.gov
- The living and working space in the station is larger than a six-bedroom house (and has six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window).
- To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day.
- Astronauts and cosmonauts have conducted 230 spacewalks (and counting!) for space station construction, maintenance and upgrades since December 1998.
- The solar array wingspan (240 feet) is about the same length as the world’s largest passenger aircraft, the Airbus A380.
- The large modules and other pieces of the station were delivered on 42 assembly flights, 37 on the U.S. space shuttles and five on Russian Proton/Soyuz rockets.
- The space station is 357 feet end-to-end, one yard shy of the full length of an American football field including the end zones.
- Eight miles of wire connects the electrical power system aboard the space station.
- The 55-foot robotic Canadarm2 has seven different joints and two end-effectors, or hands, and is used to move entire modules, deploy science experiments and even transport spacewalking astronauts.
- Eight spaceships can be connected to the space station at once.
- A spacecraft can arrive at the space station as soon as four hours after launching from Earth.
- Four different cargo spacecraft deliver science, cargo and supplies: Northrop Grumman’s Cygnus, SpaceX’s Dragon, JAXA’s HTV, and the Russian Progress.
- Through Expedition 60, the microgravity laboratory has hosted nearly 3,000 research investigations from researchers in more than 108 countries.
- The station’s orbital path takes it over 90 percent of the Earth’s population, with astronauts taking millions of images of the planet below. Check them out at https://eol.jsc.nasa.gov
- More than 20 different research payloads can be hosted outside the station at once, including Earth sensing equipment, materials science payloads, particle physics experiments like the Alpha Magnetic Spectrometer-02 and more.
- The space station travels an equivalent distance to the Moon and back in about a day.
- The Water Recovery System reduces crew dependence on water delivered by a cargo spacecraft by 65 percent – from about 1 gallon a day to a third of a gallon.
- On-orbit software monitors approximately 350,000 sensors, ensuring station and crew health and safety.
- The space station has an internal pressurized volume equal that of a Boeing 747.
- More than 50 computers control the systems on the space station.
- More than 3 million lines of software code on the ground support more than 1.5 million lines of flight software code.
- In the International Space Station’s U.S. segment alone, more than 1.5 million lines of flight software code run on 44 computers communicating via 100 data networks transferring 400,000 signals (e.g. pressure or temperature measurements, valve positions, etc.).
