OTP-2 update: 21 days into the IVO tests - OTP-2 dropped 893 meters (SMA) at 45 m/day. Yesterday we had a drop of 67m probably due to Atmospheric mass density increasing the CubeSat drag. Not looking to good so far. @RaMansell @memcculloch @RogueSpaceCorp @SJuan1797 @human1961

OTP-2 Update:@RaMansell @RogueSpaceCorp @memcculloch @SJuan1797 Does OTP have onboard thrusters to do orbit keeping- Drop rate has slowed from -4m/hour to about -2m/h. Inclination is back to where we started 97.43 deg ? Trending diff from CubeSats around OTP
