And Then There Were Two: MTU’s Next Student-built Satellite Set to Launch in 2021

5 min read

NASA has slated Michigan Technological University’s 2nd college student-crafted satellite
for a March 2021 deployment from the Intercontinental Place Station (ISS).

Stratus, named for its cloud-imaging mission, will be carried to the area station,
two hundred miles above Earth, in a SpaceX Dragon cargo capsule on a Falcon nine rocket. The
Dragon will dock to the ISS.

“Stratus will be unloaded by the crew, then placed in the Kibo Module’s airlock, where
the Japanese Experiment Module Remote Manipulator Method robotic arm will move the
satellite into the right place and deploy it into area,” mentioned Brad King, Michigan Tech’s Henes Endowed Professor in Place Systems, who has served as Aerospace Business advisor since students arrived to him with the
idea to variety a group nearly two a long time ago.

Not tricky to see how CubeSats get their identify. Stratus is a 3U spacecraft, which indicates it’s composed of three units. This photograph was
taken in tumble 2019.

The moment effectively deployed, Stratus will be the University’s 2nd orbiting nanosatellite. The initially, Oculus-ASR, was introduced from Cape Canaveral in June 2019. A different satellite, Auris, created to keep track of communications emissions from geostationary satellites, has
cleared method notion overview in the design and style and growth phase of the Air Power
Research Lab University Nanosatellite Plan (AFRL UNP). 

Monthly bill Predebon, J.S. Endowed Chair of the Department of Mechanical Engineering-Engineering
Mechanics in the Higher education of Engineering, welcomed the information of a 2nd satellite launch with praise for King and Aerospace
Business group associates. “It is awesome that Michigan Tech will have a 2nd college student-crafted
satellite in area up coming calendar year.”

“It is a testament to the creativeness, ingenuity, and arms-on ability of our students.
I am so happy of them.”Monthly bill Predebon

Stratus will use infrared imagery to obtain cloud facts that can validate and boost
numerical climate designs.
Michigan Tech Aerospace Group Plan Manager Troy Maust, a fourth-calendar year computer engineering key, has been working on the CubeSat job for about a calendar year. 

This mission has been in the works for significantly for a longer time,” he mentioned. “As with Oculus, I estimate
more than two hundred students and alumni have been part of this mission it would not be attainable
devoid of them. I am delighted to see these yrs of tricky do the job pay back off.”

The ten-by-ten-by-thirty-centimeter, 4.4-kilogram Stratus CubeSat is substantially lesser
than the 70-kilogram Oculus-ASR, a microsat which actions fifty-by-fifty-by-80 centimeters.
But the two, as well as Auris, are classed in the broader classification of nanosatellites,
the craft that signify an important growth in area sector developments. 

“In the past, satellites have been substantial, multimillion-greenback jobs,” Maust mentioned.
“While substantial satellites are nonetheless currently being crafted, there is a change towards applying various
lesser spacecraft in a constellation. Aside from decreasing the over-all price, constellations
can offer protection unfold around a greater location. Stratus is an illustration of applying this
mindset for climate satellites.” 

Upcoming Measures for Stratus: FlatSats and Day in the Existence

“All of this will keep us active until our December 2020 handover date.”Troy Maust

The COVID-19 international pandemic has afflicted college accessibility all around the planet, and
Michigan Tech is no exception. Maust mentioned significantly remains to be performed. But as Huskies
who relentlessly labored to
prepare Oculus-ASR for its launch can attest, this is not the initially time the Aerospace Business has contended with
unexpectedly condensed timelines.  

Method degree screening will just take spot as shortly as campus is ready to reopen. “We’ll continue on
with FlatSat 1 and two,” Maust mentioned. The names are explanatory and the techniques are vital
right before the CubeSat is entirely assembled. Spacecraft factors are laid flat on the
workbench and linked to the CubeSat’s subsystems to validate that the method works
with each other as a total.

“Next comes DITL 1 and two, or Day In The Existence,” mentioned Maust. Yet again, the identify is apt.
“The tests simulate the actions our assembled spacecraft will complete in a working day, with
the closing take a look at running for a complete 24 several hours,” Maust mentioned. “Vibration and thermal vacuum
screening will also be executed to make sure the spacecraft can withstand the severe problems
of launch and area.”

The process of creating, setting up and flying a spacecraft is multifaceted, which
is why the Aerospace Business, 1 of the major at Michigan Tech, welcomes
associates from disciplines across campus and is arranged into many subteams. Even though Stratus method-degree screening is using
spot, one more subteam will be working on procuring any vital Federal Communications
Fee (FCC) and National Oceanic and Atmospheric Administration (NOAA) licensing.
“This can be a very long process and need to be commenced well in progress of launch, as we will
not be permitted to continue on devoid of the right licensing,” Maust mentioned.

In 2016, Michigan Tech was picked to fly Stratus as an auxiliary payload. In early
December 2019, a
NASA-Goddard Spaceflight Center group done a comprehensive critical design and style overview,
or CDR. “While we experienced a several nicks and dings from the occasion, as is widespread for the duration of
CDR, we passed and had been ready to move on to method integration in planning for an
impending launch,” King mentioned. 

“Winning the NASA launch was wonderful information, but our celebration was quick. Out of the blue our
’to-do’ listing has gotten a great deal for a longer time and the stakes have gotten a great deal greater.”

“I know these students can handle whatsoever troubles lie waiting amongst here and
orbit. Like it was with Oculus, we will have our huge celebration when we see the rocket
heading skyward.”Brad King

Michigan Technological University is a community research college, home to more than
7,000 students from fifty four countries. Launched in 1885, the University features more than
a hundred and twenty undergraduate and graduate degree systems in science and know-how, engineering,
forestry, business enterprise and economics, wellbeing professions, humanities, mathematics, and
social sciences. Our campus in Michigan’s Upper Peninsula overlooks the Keweenaw Waterway
and is just a several miles from Lake Remarkable.
