FEATURES Autonomous Mission for On-Orbit Servicing: Promoting a Sustainable Space Environment 4 The amount of tracked debris objects has increased by more than 50% for all Earth orbits in the past decade. Action is needed to stem the debris population increase and foster a sustainable Low Earth Orbit environment. byPaulLemon,RoxanneCote-Bigras,andPatrickGavigan My Transatlantic Teatime with Venetia: Remembering a Conversation with the Girl Who Named Pluto 10 As New Horizons nears its close encounter with Pluto and provision of Earth images to millions, let us be reminded of the retired English schoolteacher who decades ago at age 11 named this distant planetary body. byEdwardGoldstein Aerojet Rocketdyne Employees Bid Farewell to MESSENGER The end of NASA MESSENGER’s decade long mission is bittersweet to Aerojet Rocketdyne 14 employees.

NASA MaterialsLab Changes Materials Research on the International Space Station 15 A new approach to materials science research called MaterialsLab provides an unprecedented level of collaboration among stakeholders performing research on the International Space Station, a unique orbiting laboratory where advanced materials can be studied and used to stimulate the U.S. economy.
