Lorna Brooke s family and friends turned out to remember her at a special memorial event at Ludlow Racecourse.
Brooke, who enjoyed more winners at the track than any other venue, died last month following a fall at Taunton.
Aged 37, the talented amateur had been welcomed back into the Ludlow winners enclosure on six occasions.
On Monday afternoon, Brooke s loved ones gathered around it to cheer in Our Rockstar (6-4f), who came home first in the Lorna Brooke Amateur Jockeys Handicap Hurdle.
ZIGBEE ON MARS!

Today I learned that the Ingenuity drone copter twirling about on Mars communicates with the Perseverance rover using 900MHz Zigbee radios. Not Wi-Fi, GSM, or something exotic like fission-powered lasers or space algae, but the same consumer tech you use to turn on a Philips Hue lightbulb.
I came across the news via an incredulous tweet from Ben Bromley who discovered it on the Linux Unplugged podcast with guest Tobin Richardson, CEO of the Zigbee Alliance, recently rebranded the Connectivity Standards Alliance.
According to Richardson, Zigbee is the ideal wireless protocol to transfer telemetry data between NASA’s Perseverance rover and the semi-autonomous flying drone. “Looking at really extreme environments, like Mars, it’s good to have a very lightweight purpose-built standard,” said Richardson, “where it’s essential to get the basic information across and makes it possible for extended battery usage.”
