NSW software program engineer forges area trade profession capturing satellite-to-satellite pictures
An Australian software program engineer says “complicated” new area expertise, of which she is among the many first on the earth to work with, will assist handle the large quantity of objects orbiting in area.
Samantha Kirkwood, 24, is employed as a analysis and growth engineer with an Australian area trade startup.
“We are able to truly take diagnostic pictures of issues in orbit, from orbit, so we’ve cameras which are orbiting round Earth,” she mentioned.
“From the photographs, we will work out of there may be harm to satellites or if every part up there may be working appropriately.”
Satellites watching satellites
Ms Kirkwood’s position could be very new.
Her Sydney-based employer’s satellite tv for pc software program inspection expertise solely grew to become operational in August 2022.
“We are the first personal firm on the earth to offer in-orbit inspection commercially,” Excessive Earth Orbit (HEO) Robotics co-founder and chief government Dr Will Crowe mentioned.
The corporate makes use of its software program with satellites already in orbit and now has entry to a community of 35 high-quality cameras in area.
Ms Kirkwood mentioned having the capability to evaluate orbiting satellites, in addition to area junk and unknown area objects, was changing into more and more essential.
“Lots of people do not realise how a lot we do depend on the satellites which are in area — GPS satellites and climate evaluation for instance — and there are increasingly satellites going into orbit,” she mentioned.
“Issues in orbit are fairly arduous to troubleshoot when they’re a whole lot of kilometres above your head and travelling in a short time.”
“There are hundreds upon hundreds of items of area junk in orbit and sometimes bits of particles can collide with operational satellites as nicely.”
Capturing in-orbit pictures
The cameras seize “fly-by” pictures of objects and satellites, together with the Worldwide House Station (ISS) as they zip previous in nanoseconds.
Ms Kirkwood mentioned it was a “complicated” activity.
“The satellites are travelling at a velocity of about 7 kilometres a second, relative to Earth, so it’s totally, very quick, and since we’re imaging from different satellites, that is as much as a relative velocity of 15 kilometres a second,” she mentioned.
“We additionally take pictures from about 100 kilometres away … so issues are shifting very quick and fairly far-off and we have to inform our cameras precisely the place to level.
“There’s a whole lot of modelling that goes into that and a few software program we’ve constructed to do all these calculations for us.
“It is a actually nice feeling after we do all that work after which get a improbable image of the Worldwide House Station, for instance.”

Constructing from the bottom up
Ms Kirkwood grew up on the Mid North Coast of NSW with desires of changing into an astronaut.
She found her ardour for science and area whereas on the Camden Haven Excessive College, close to her hometown of Laurieton.
“I bear in mind recommendation I bought in highschool, that the job which you can have in 10 years would not exist proper now,” she mentioned.
“It is arduous to think about while you’re a teen, however it’s positively true.”
Ms Kirkwood graduated in 2021 with a Bachelor of Superior Science (Physics) and Bachelor of Laptop Science and additionally did an honours challenge in astrophysics.
She mentioned it was “very thrilling” to now be a part of the small however rising area trade in Australia.
“We solely established the Australian House Company right here in 2018,” she mentioned.
“We’re actually constructing this trade right here from the bottom up in the intervening time.”
HEO Robotics has additionally been steadily increasing and now employs 20 individuals, the bulk in Australia with a small staff within the UK and US.
House desires
In the meantime, Ms Kirkwood hasn’t misplaced her dream of at some point travelling to area.
She mentioned Australia had “thrilling plans” to be concerned in NASA’s Artemis program to return astronauts and ship the primary feminine astronaut to the moon.
“Like many individuals, I might like to go to area, so we are going to see the place that highway goes for me,” she mentioned.
“It is positively no simple feat to grow to be an astronaut … a far-out dream of mine, however we’ll see.”
