China’s Lunar Sample Return Mission Slips

Jeff Foust (@jeff_foust) of Space News is live tweeting news from the International Astronautical Congress in Adelaide, Australia. Yesterday Tian Yulong of China’s space agency (CNSA) confirmed what many expected — the launch of the Chang’e-5 lunar sample return mission will be delayed because of the failure of China’s new Long March 5 rocket in July.

Chang’e-5 was supposed to launch in November of this year. Jeff’s tweet also says Chang’e-4 will be delayed. Originally designed as a back up to China’s lunar lander/rover Chang’e-3/Yutu, Chang’e-4 is being reformulated as a spacecraft to land on the Moon’s far side. If successful, it will be the first spacecraft to do so. Launch was expected in 2018 (preceded by a communications relay satellite to enable the lander to communicate back to Earth).

Corporate Personnel Changes at Northrop Grumman

Two top executives at Northrop Grumman will retire at the end of the year according to a company announcement. Northrop Grumman is in the process of acquiring Orbital ATK.

Northrop Grumman’s Chief Operating Officer (COO), Gloria Flach, and Corporate Vice President for Government Relations, Sid Ashworth, will retire.

Kathy Warden will become President and COO of the company on January 1, 2018. She is currently Corporate Vice President and president, Mission Systems. She will oversee the company’s three operating sectors and the integration of Orbital ATK into the company once that transaction is complete (expected in the spring of 2018).

Mark Caylor will succeed Warden as Corporate VP and president, Mission Systems.

Shawn Purvis will become Corporate VP and president, Enterprise Services.

Lesley Kalan will succeed Ashworth as Corporate VP, Government Relations.

Wes Bush, chairman, CEO, and (currently) president of Northrop Grumman thanked Flach and Ashworth and welcomed the others to their new roles “as we continue to focus on driving top performance for our customers, shareholders and employees.”
