The microsatellite Hypso-1 is a rarity because it has a mainly Norwegian-developed payload to be used for research. The satellite will be launched as part of Spacex’s Transporter 3 launch with the Falcon 9 rocket. This is the company’s recycling rocket .
The launch will be according to plan take place on Thursday at 16.25 Norwegian time (see video at the bottom of the case). If they are not allowed to launch the rocket within the 29-minute time window they have sat down, they have the opportunity to try again on Friday at the same time.
There is a group of researchers at NTNUs Smallsat lab that has developed the satellite. Roger Birkeland and Sivert Bakken, two of the developers, tell TU that the launch is an important milestone.
– It is important that Norwegian players can help build payloads in small satellites. Hopefully there will be more of this, says Birkeland.
Will follow algae
The payload is a hyperspectral camera that was developed for, among other things, Northern Lights research. The microsatellite developers have adapted the camera to withstand the extreme environment in the room.
The camera will be aimed at the earth and especially the Norwegian coast where it will help to follow algae blooms. This can, among other things, contribute to research on the connection between algae blooms and sea temperature.
The satellite will also be part of research on how satellites and unmanned surface craft can collaborate on ocean monitoring.
After launch, it will take about one month for developers to know if the satellite is working properly or not. First the launch must go well, then the satellite must deploy properly and finally all the functions must be tested.
Excited
– I’m excited about whether the components work properly – especially how the degradation of the sensitivity of the cameras will be. It is a harsh environment up there, so it will be exciting to see how the examiners do, says Bakken.
He and Birkeland are in the process of preparing the recipient on the roof of the university, while the project manager Evelyn Honoré-Livermore will follow the launch from Florida.
There are a number of satellites that use hyperspectral cameras for Earth observation from before, but few that have cameras that are sensitive enough to observe algae in the ocean , according to the developers.
Hypso-1 will be launched in an orbit between 500 and 600 kilometers above the earth. It must go in polar and solar synchronous orbit. The former means that it passes both poles. The solar-synchronous orbit means that the light from the sun hits the earth in the same way when the satellite takes pictures in a given place, which makes the light conditions comparable on several observations.
Starting with the next version
The Transport 3 launch is a so-called rideshare launch where many small satellites will be launched, but it is not a large satellite as the main load.
Hypsy-1, which stands for hyper spectral satellite for ocean observation, is 10x20x30 centimeters large. It will be part of the larger microsatellite package M6P multi-purpose nano-satellite bus from the company Nanoavionics.
Initially, the satellite was to be launched in 2019 or 2020, but it was postponed.
Work on the follow-up satellite Hypso-2 has already begun. It will also carry a hyperspectral camera, the developers say.
In 2018, Bakken explained
