The twice-delayed launch of the United Launch Alliance (ULA) Delta II rocket that will transport the AMSAT RadFxSat (Fox-1B) CubeSat carrying an Amateur Radio payload and other payloads into orbit now is set for Saturday, November 18, at 0947 UTC. The Joint Polar Satellite System (JPSS)-1 mission launch from Vandenberg Air Force Base, California, had […]

via the ARRL: AMSAT Poses RadFxSat (Fox-1B) Telemetry Reception Challenge

AMSAT is urging satellite enthusiasts to get their FoxTelem telemetry software up and running, in anticipation of the launch of RadFxSat (Fox-1B). It will carry a Fox-1 style FM U/V repeater with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. Satellite and experiment telemetry will be downlinked via the […]

via the ARRL: RadFxSat (Fox-1B) Launch Scrubbed Again, but More Foxes are on the Way!

The launch of the already-delayed United Launch Alliance (ULA) Delta II rocket that will transport the RadFxSat (Fox-1B) CubeSat carrying an AMSAT Amateur Radio payload and other payloads into orbit was scrubbed on November 14, with just over 15 minutes to liftoff. “The launch of a United Launch Alliance Delta II rocket carrying the JPSS-1 […]

via the ARRL: Simple 40-Meter Dipole Supports Advanced Mars Radar

The venerable HF dipole has found a new home and purpose in space. The Mars advanced radar for subsurface and ionospheric sounding (MARSIS) on Mars Express uses a simple 40-meter dipole as the antenna for its subsurface sounding radar. The dual-channel low-frequency sounder operates between 1.3 and 5.5 MHz for subsurface sounding and between 100 […]

via the ARRL: RadFxSat (Fox-1B) Launch Delayed; AMSAT Asks for Patience During Commissioning

The launch of the Delta II vehicle carrying RadFxSat (Fox-1B) and other payloads has been delayed, due to a faulty battery on the booster, United Launch Alliance (ULA) announced on November 6. The launch now is scheduled for no earlier than Tuesday, November 14. RadFxSat is one of four CubeSats making up the NASA ELaNa XIV mission, riding as […]

Zombie Satellites – Should We Fear the Graveyard Orbit of Un-dead Satellites?

If you’re prepared for ghosts, ghouls and goblins this Halloween, you might want to also consider zombies…satellites that is. Deep in outer space, where machines orbit the Earth, they share the sky with the un-dead. Can these historic satellites come back to life? HOW DO SATELLITES DIE? After a satellite completes its useful life and […]
