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.

It was afternoon in Florida when SpaceX launched its Falcon Heavy rocket from Cape Canaveral on its first commercial mission. The most powerful rocket in activity launched the Arabsat-6A satellite, which after about 34 minutes separated from the rocket’s last stage entering a transit orbit from where it started the maneuvers that will take it towards a geostationary orbit within a bit more than two weeks.

At a press conference, NASA administrator Jim Bridenstine announced the new version of the agency’s plans to bring astronauts back to the Moon and build the Lunar Gateway over the next decade as steps to bring astronauts to Mars during the 2030s. Jim Bridenstine referred to the NASA budget for 2020, which at $21 billion sees an increase granted also to push ahead with these new plans.

It was morning in California when SpaceX started a new record mission with the launch from the Vandenberg base of a Falcon 9 rocket whose first stage was on its third flight. Everything worked well, including the third controlled landing. In the meantime, the second stage brought a group of 64 small satellites into orbit and within about half an hour they were put into a Sun-synchronous orbit, hence the name SSO-A SmallSat Express mission. For SpaceX it was the 19th mission of the year, passing the 18 completed in 2017.

At a press conference, NASA administrator Jim Bridenstine announced the new plans for the return to the Moon with the inclusion of a number of private companies that will have the chance to provide their services to send various types of payload. The program called Commercial Lunar Payload Services (CLPS) could start as early as 2019 and represents a first step towards a long-term goal, that is to establish a permanent presence on the Moon with an eye to Mars.
