University of New Brunswick group tracks astronaut Jeremy Hansen’s progress within the heavens

For many house lovers, following the Artemis II mission has meant tuning into NASA’s on-line livestream and watching the 4 crew members, together with Canada’s Jeremy Hansen, work of their minivan-sized capsule.

But one group on the University of New Brunswick has had a extra direct connection to the mission this week that they first demonstrated earlier than daybreak final Saturday.

On that morning, with assistance from a repurposed satellite tv for pc dish atop the college’s engineering constructing in Fredericton, the group was in a position to efficiently choose up the radio sign broadcast from the spacecraft, permitting them to find out its place whereas it was nonetheless on its method to the moon.

“I was very excited immediately,” mentioned Megan MacDonald, a grasp’s scholar in electrical engineering, describing the second when the sign got here in. “It was so clear on the graph and so visible that I wondered for a second if we were pointed at a satellite much closer.”

However, the sign was at precisely the frequency and elevation anticipated from Artemis II, “so it couldn’t be anything else,” she added.

The frequency was additionally reducing over time, an impact known as the Doppler shift, due to the capsule’s speedy movement away from Earth at that time within the mission.

Since then, the group of half a dozen volunteers, together with college students, has been following the progress of the spacecraft by way of the heavens. They made one closing detection on Friday morning, forward of the crew’s anticipated return at 8:07 p.m. ET, and adopted the spacecraft’s sign earlier than it disappeared over the horizon, as Earth rotated it out of view.

Data that have been gathered by the group over the course of the week will likely be despatched to NASA for evaluation.

The University of New Brunswick was certainly one of 34 floor stations in 14 international locations chosen by NASA earlier this 12 months to help with monitoring the lunar mission, which launched on April 1.

NASA depends on its Deep Space Network – a sequence of a giant receivers at areas that wrap across the globe – to keep up communication with Artemis II. But monitoring knowledge gathered by volunteer teams can present added precision on the situation of the spacecraft on numerous factors through the mission.

“They’ll use all of that information from all the other observing stations to help characterize or to check if we’re doing things okay, and it’s an additional verification of their existing Deep Space Network,” mentioned Brent Petersen, a specialist in digital communications and a professor in UNB’s division {of electrical} and pc engineering.

NASA has mentioned the initiative is meant to assist business and tutorial teams develop capabilities that could possibly be utilized sooner or later when the tempo of flights to translunar house is predicted to extend.

In its unique name for contributors, NASA really useful that every station have a receiver dish measuring at the very least 9 metres throughout. However, the UNB group has managed to choose up the sign with a repaired 1.8-metre diameter dish that had as soon as been used to choose up TV alerts from satellites in geostationary orbit.

“Ours is the little dish that could,” mentioned Richard Langley, a professor in geodesy and geomatics who, together with Dr. Petersen, has supplied school help for the challenge.

He mentioned the problem of efficiently pinpointing and choosing up the Artemis II sign supplied college students with a superb real-world instance of apply communications expertise.

“It was pretty cool to share in the excitement,” mentioned Olivia Gerry Rice, a pc science undergraduate who helped to interpret the incoming sign and its behaviour.

Ms. MacDonald mentioned she felt lucky that the mission was beneath manner at simply the best time for her to take part whereas engaged on her graduate diploma.

“From my perspective as a younger person, I feel like interest in space kind of ebbs and flows,” she mentioned.

She added that Artemis II – and hopefully different lunar missions to come back – have supplied college students with an opportunity “to feel so connected and involved in a hands-on way with something that’s going on right now.”
