QB50 Challenger

Also, a huge thank you to all the radio operators out there that sent data to us and helped keep it fun. You are awesome!

We are saddened that @QB50Challenger is now gone, but look forward to the CU-E3 cubesat and the @maxwellcubesat coming out of @CUEngineering in the near future. MAXWELL will be built directly from Challenger hardware so check them out! Officially signing off. 🛰️ #CubeSat #QB50

@JA0CAW @QB50Mission Looks like she is finally gone!

@QB50Challenger @QB50Mission 21:53 UTC nothing heard over Japan 😂

Signs that @QB50Challenger might be gone. Let us know if you hear anything! @QB50Mission #QB50

Date: 10/8/18 12:19 Apogee: 222.6729 km Perigee: 204.6325 km Place your bets! Getting more eccentric and may be gone in a day or two! Listen closely for me! @QB50Mission #QB50

229.15 km and falling! 7 km in one day! Just a few days left potentially.

Getting close now! Current Challenger Altitude Date: 31/7/18 20:15 Apogee (km): 260.7301 Perigee (km): 255.2977

Dropping fast now. Apogee has gone down 6 km in 4 days. Keep listening as it will not be long until deorbit. @QB50Mission #QB50 Date - 18/7/18 10:14 Apogee (km) - 285.2996 Perigee (km) - 277.8487

Current Altitude of Challenger. It will not be long now until de-orbit!

MAXWELL earns top scores from the Air Force. A CU Boulder aerospace CubeSat project has been selected as a winner in the @USAirForce University Nanosatellite Program Flight Selection Review. colorado.edu/aerospace/2018…

Challenger will be entering a low beacon rate for the next few days. We are currently in a weird attitude state and not charging as quickly.

@JA0CAW @QB50Mission Received! Thank you!

@JA0CAW @QB50Mission Thank you! You can send all data/information to Andrew.dahir@Colorado.edu

@JA0CAW @QB50Mission Thank you! We're these one second beacons you were receiving? Our radio is currently not accepting commands.

@JA0CAW @QB50Mission I'll check the beacon rate and get back to you! Thanks for continuing to check telemetry!

@JA0CAW @QB50Mission Thank you! Our radio has been doing some weird things lately. We have not been able to decode/command either. Waiting for reset tomorrow.

@JA0CAW @QB50Mission Thank you! We have not been able to detect a signal for the last two days. Believe SAA messed us up. Waiting for Auto Radio Reset

@JA0CAW @QB50Mission Great question, let me check on that.

Still going strong! Nearly fully charged to begin further commissioning!

@INSPIRE_2_SAT @ACSERUNSW @QB50Mission Can confirm, the TLEs are swapped. We are using UNSW to locate Challenger.
