A whole bunch of post-secondary college students in New Brunswick are patiently ready for a name from Satellite tv for pc Violet. The scholar-built challenge took greater than 5 years to develop at campuses throughout the province and isn’t speaking as anticipated.
The satellite tv for pc was delivered by a rocket to the Worldwide House Station in early March and despatched into Earth’s orbit on Apr. 18. Satellite tv for pc Violet, named after the provincial flower, is the primary New Brunswick-built satellite tv for pc to be blasted into area.
Whereas these long-distance calls proceed to go unanswered, Troy Lavigne, one of many program’s challenge officers, stated it’s not a “big” shock that the satellite tv for pc hasn’t responded instantly.
“There’s a reasonably sophisticated system in place for us to speak with Violet,” he stated.
The bread-loaf-sized satellite tv for pc was a joint effort amongst greater than 300 college students and college on the College of New Brunswick, the Université de Moncton, and New Brunswick Group Faculty as a part of the bigger Canadian CubeSat challenge, involving 15 instructional establishments all through the nation creating satellites.
Lavigne stated Violet’s remoted behaviour might be defined by its antennas not deploying but. If that’s the case, a fishing wire that’s holding the antenna down is anticipated to soften in just a few weeks.
“We chosen that fishing line as a result of we all know it should degrade naturally after a few weeks in outer area…then we can talk with Violet,” he defined.
The challenge’s goal is to check and acquire information surrounding the uppermost a part of the earth’s ambiance, generally known as the ionosphere, for between three months to 2 years.
Lavigne added that some recognized points at a newly constructed floor station in New Brunswick may have additionally performed a task, which has since been resolved.
“We’ve obtained radio receptions from different satellites, so we’re working by way of the potential that we’re sending a command to Violet however we’re not in a position to decide (a response) up,” he stated.
If the satellite tv for pc’s radio silence hasn’t been attributable to both state of affairs talked about, there’s one remaining choice that would lead to Violet lastly transmitting info again to Earth — or present an abrupt ending to its long-awaited journey into outer area.
Researchers hope Violet will ship details about the ionsphere, the place “ultraviolet gentle and x-ray photo voltaic radiation trigger electrons to pop freed from their atomic and molecular bonds leaving ions behind,” as famous in a UNB launch.

“If the antenna is stowed, then (info) received’t transmit as a result of it’s broken,” Lavigne continued, including {that a} secondary “transmit whether or not the antenna is deployed or not” command may be despatched after just a few extra weeks of ready.
“Though that would trigger injury to Violet, that’s a threat we’re keen to take somewhat than not know if Violet’s ever in a position to reply. We’ll solely try this after just a few weeks have handed and we’ve determined it’s price that threat.”
Regardless of the preliminary lack of communication so far, Lavigne stated his group isn’t giving up.
“Violet may’ve been broken and should by no means reply. We’re hoping that’s not the case and we’re working by way of all these prospects.”
Both manner, he stated the challenge will probably be thought-about an awesome success, because the objective was at all times to adequately put together the subsequent technology of area business professionals for careers inside the discipline.
Scholar stays hopeful
Samiha Lubaba, a grasp’s scholar on the College of New Brunswick, was recruited to the Violet group in August 2023 and remains to be aiding with the communication efforts on the bottom.
Though all the things appeared to reply accordingly when Violet was nonetheless inside the group’s possession on Earth, Lubaba stated troubleshooting is a extra sophisticated course of as soon as the satellite tv for pc is hovering above.
“There may be so many issues concerned within the communication,” she stated, including that her group will proceed making an attempt regardless of not receiving the response that they have been anticipating.
Though the dearth of communication is demanding, Lubaba stated her group of researchers nonetheless has about “seven or eight” alternate options that would lead to Violet transmitting the primary bit of knowledge that the bottom station crew is so determined to listen to.
“I imagine it should work,” she stated. “Perhaps it’s taking a while, however I’m not hopeless. Perhaps it should take two weeks, three weeks, or extra.”
If the Violet crew is ready to overcome the communication dilemma and make contact with its orbiting good friend, Lubaba stated she will probably be very relieved.
