2. Emergency Messaging Demonstration for Red Cross, FEMA is a Success

With Red Cross and Federal Emergency Management Agency (FEMA) officials monitoring, dozens of radio
amateurs along the US east coast on May 23 demonstrated Amateur Radio’s ability to deliver messages
without commercial power, infrastructure, or permanently established stations.
The demonstration was a mock response to a simulated disaster scenario — a major hurricane with mass
casualties. During the event, radio amateurs at portable stations from New England to the Carolinas
delivered message traffic to W1AW, which coordinated and delivered the information to officials
attending a joint Red Cross-FEMA meeting in Baltimore.

Red Cross officials were on-site at W1AW and at the receiving station in Baltimore. At both sites,
they indicated that were impressed with Amateur Radio’s ability to deliver messages digitally that
could be displayed on a computer screen and in a format that matched the format for messages that
the Red Cross uses.

Amateur Radio operators and the partner agencies they serve are getting ready for 2018 Hurricane
season. Hurricane Season begins on June 1 and continues through November 30.

W1AW Station Manager Joe Carcia, NJ1Q, said the exercise went well overall. “Conditions were a bit
tepid at best, but we were able to establish voice contact first, and then proceed with the digital
traffic (MT63-1KS) during the roll call,” Carcia said. “Digital signals were good. I needed just
one retransmit. We used fldigi with flmsg. This made life so much easier.”

3. Lightsail-2 scheduled for launch June 22 - Beacon on 437.025 MHz

LightSail is a citizen-funded project from The Planetary Society.
This cubesat will be propelled solely by sunlight, to Earth orbit. LightSail 2 is scheduled to launch
aboard a SpaceX Falcon Heavy on June 22, 2019, and attempt the first, controlled solar sail flight in Earth orbit.

LightSail 2 will ride to space aboard the Department of Defense STP-2 mission which will send 24 spacecraft
to 3 different orbits. LightSail 2 itself will be enclosed within Prox-1, a Georgia Tech-designed spacecraft
originally built to demonstrate close-encounter operations with other spacecraft.
Prox-1 will deploy LightSail 2 seven days after launch.

After a few days of health and status checks, LightSail 2's four dual-sided solar panels will swing open.
Roughly a day later, four metallic booms will unfurl four triangular Mylar sails from storage.
The sails, which have a combined area of 32 square meters [344 square feet], will turn towards the sun for
half of each orbit, giving the spacecraft a tiny push no stronger than the weight of a paperclip.
For about a month after sail deployment, this continual thrust should raise LightSail 2's orbit by a measurable amount.

LightSail 2 will fly in a 24-degree inclination, 720 km, circular orbit.
At latitudes of 42 degrees north it will reach a maximum elevation of 10 degrees above the horizon.

Lightsail-2 has been issued an experimental radio license WM9XPA and transmit on 437.025 MHz.
A morse beacon will transmit the callsign every 45 seconds. A packet beacon will transmit AX.25, FSK 9K6 bps data.
