A little while ago 60 satellites of the Starlink constellation were launched on a Falcon 9 rocket from Cape Canaveral. After about an hour they were successfully deployed into their orbit at an altitude of about 280 kilometers all together and then started slowly disperse. This is SpaceX’s second mission to put the Starlink constellation into orbit to provide a global Internet connection coverage.

A few hours ago a Vega rocket was launched from the Kourou base, in French Guiana, to deploy the United Arab Emirates’ Falcon Eye 1 satellite. About two minutes after the launch, immediately after what was supposed to be the second stage’s ignition there was an anomaly that caused the mission’s failure. This is the first failure for the Vega rocket after 14 successes.

A few hours ago SpaceX launched its Falcon Heavy rocket from Cape Canaveral on a mission involving the launch of various satellites in low and medium Earth orbit. The most powerful rocket in business launched satellites on behalf of NASA, the US Air Force and other entities, incuding CubeSat-class nanosatellites built by students. The mission required four burns for the Falcon Heavy rocket’s upper stage to place them in the various orbits required. The mass of the payloads to be taken into orbit was relatively small – around 3,700 kg – but the second stage needed a lot of fuel to carry out all the maneuvers required in this mission, therefore the initial thrust of the Falcon Heavy was needed.

NASA’s Launch Services Program (LSP) announced the conclusions of a long investigation into the failure in the launch of its OCO and Glory satellites in 2009 and 2011. In both cases, the fairing on top of the rockets that protected the satellites didn’t separate and the extra weight caused the the satellites to fall down. The investigations revealed falsifications by the contractor Sapa Profiles, Inc. (SPI) that provided defective materials with false certifications. The investigation involved the US Department of Justice.
