SkyTour Radio Presents: Oh Canada! The Canadian Connection
Sunday July 1st, 2018
In this week’s special episode of SkyTour Radio, and in honor of it being Canada day, we take a closer look at the contributions Canada has made to space, the space program and bringing understanding of space closer to home.
In our weekly exoplanet roundup, we look at K2-18 b and c, both discovered by Canadians from the University of Toronto, where the confirmation of one lead to the discovery of the other!
Then, we discuss one of Canada’s most famous robotic and technological achievement, the Canadarm 1 then later followed by the Canadarm 2.
K2-18 b is an exoplanet orbiting the red dwarf star K2-18 every 33 days, found in the constellation Leo. K2-18b is within the habitable zone of its star and could haveoceans of liquid water on its surface, and may have a rocky surface and an atmosphere providing similar insulation to Earth’s.
The discovery of K2-18 b provided strong evidence for a second, warm super-Earth K2-18c.The discovery of the inner planet K2-18c further emphasizes the prevalence of multi-planet systems around M dwarfs.
The Shuttle Remote Manipulator System (SRMS), also known as Canadarm (Canadarm 1), is a series of robotic arms that were used on the Space Shuttle orbiters to deploy,maneuver and capture payloads.
The basic Canadarm configuration consists of a manipulator arm, a Canadarm display and control panel, including rotational and translational hand controllers at the orbiter aft flight deck flight crew station, and a manipulator controller interface unit that interfaces with the orbiter computer.
The Canadarm can also retrieve, repair and deploy satellites, provide a mobile extension ladder for extravehicular activity, crew members for work stations or foot restraints, and be used as an inspection aid to allow the flight crew members to view the orbiter’s or payload’s surfaces through a television camera on the Canadarm.
Canadarm2 is part of Canada’s contribution to the International Space Station (ISS) and is a 17-metre-long robotic arm and was extensively involved in the assembly of the orbiting laboratory. It also performs Station maintenance, moves supplies, equipment, Dextre and even astronauts and perform “cosmic catches” by grappling visiting vehicles and berthing them to the ISS.
Each end of Canadarm2 features an identical “hand,” known as a Latching End Effector. These pieces contain cables that tighten to ensure a strong grip. They allow the robotic arm to firmly grasp objects or latch itself to the Station. Each of its end scan be used as an anchor point while the other carries out various tasks.
So, join us as we celebrate Canada and all the helpful contributions the country has made in pursuit of finding the answers that space holds for all of humanity.
SkyTour Radio explores the Universe in a down to Earth manner explaining the science we know in fun and bite-sized terms. Science is for everyone and people shouldn’t require an advanced degree to understand as long as it is delivered in an easy to follow way. From Black Holes to Extraterrestrial Life, we will explore the Universe like never before. Join us to check out such things as how stars form, how they live and, how our fate is intertwined with theirs. On the extraterrestrial life front, we will be speaking to the UFO and science arena’s top researchers and bring UFOlogy into the 21st century.
