Prepping for a spacewalk usually means diving underwater to rehearse and fine-tune operations.
In 2016, ESA astronaut Alexander Gerst carried out such an underwater rehearsal for the Colka excessive velocity radio, the brown field imaged above, that will probably be put in this month on the Worldwide House Station.
NASA astronauts Mike Hopkins and Victor Glover will combine the small fridge-sized gadget exterior the European Columbus module throughout a spacewalk scheduled this 12 months. ESA astronaut Andreas Mogensen will probably be at NASA’s mission management directing the spacewalkers as Capcom. The Columbus Ka-band terminal, nicknamed ‘Colka’, will allow sooner communication with Europe.
Orbiting the planet each 90 minutes means the House Station is continually making and breaking quick hyperlinks with floor stations on Earth because it passes over them at a top of 400 km.
With Colka, a European telecommunications satellite tv for pc in geostationary orbit can choose up knowledge despatched from the Columbus module. This satellite tv for pc is a part of the European Information Relay System and can have the ability to instantly relay the indicators from Columbus to European soil through a floor station in Harwell, within the UK.
The present knowledge relay system routes through USA, which ends up in longer knowledge switch instances. The Colka improve will guarantee sooner communications between Columbus and Europe, speeds of as much as 50 Mbit/s for downlink and as much as 2 Mbit/s for uplink. It will enable astronauts and researchers to profit from a direct hyperlink with Europe at house broadband speeds – delivering an entire household’s value of video streaming and knowledge for science and communications.
Colka will probably be put in simply weeks after the announcement that Europe will begin constructing a communications module in help of the Gateway, the following spaceship to be assembled and operated within the neighborhood of the Moon by Worldwide House Station companions. The ESPRIT Excessive-speed Lunar Communication System will probably be launched on NASA’s Gateway residing quarters, in 2024.
As humankind ventures farther from Earth and goes ahead to the Moon, a sturdy communications infrastructure is critical for the lunar financial system and to return information and advantages to Earth. ESA is engaged on this with the Moonlight venture, a system for lunar telecommunications and navigation to cut back design complexity, liberating missions to focus on their core actions.
ColKa was designed and constructed by British and Italian corporations, utilizing merchandise from Belgium, Canada, France, Germany and Norway, a few of which have been certified below the ESA’s programme of Superior Analysis in Telecommunications Methods (ARTES).
