ADRAS-J mission takes methodical first steps toward the commercial removal of space debris
The recent increase in launches to meet growing demands for communications and observation satellites is adding more and more spacecraft to orbit every year. This is especially true in the more congested low-Earth orbit (LEO). With a sharp focus on making space safe and sustainable for the current as well as future generations, organizations such…

Crewed missions, new modules, and orbital debris — the ISS’s busy November
November was an eventful month for the International Space Station (ISS) and its crew members. From spacecraft departures and arrivals, new modules, science experiments, and close calls with orbital spacecraft debris, the Expedition 65 and 66 crews stayed busy aboard the orbiting laboratory. The ISS and its crew kicked off November with the docking of…

Russia tests anti-satellite missile, debris disrupts International Space Station
Russia’s Kosmos 1408 satellite was destroyed in orbit earlier on Tuesday in what appears to have been a demonstration of Russia’s Nudol anti-satellite missile. While the Russian government has not yet acknowledged the cause of the satellite’s breakup, concerns about debris from the satellite have already disrupted operations aboard the International Space Station and could…

Mission Extension Vehicles succeed as Northrop Grumman works on future servicing/debris clean-up craft
With the successful docking of Mission Extension Vehicle 2, or MEV-2, to the Intelsat 10-02 satellite last month, Northrop Grumman not only repeated the task of successfully attaching one of their MEV spacecraft to a functioning satellite but also successfully proved the ability to grab a still-transmitting telecommunications satellite without disrupting service. The success of…

Orbiter related Ice liberation threat discussed ahead of STS-119
Following a run of “clean” flights during 2008 – thanks to continued progress in reducing foam liberation from the External Tanks – the Space Shuttle Program (SSP) Flight Readiness Review (FRR) focused on the threat of ice liberation during ascent for 2009’s opening mission, STS-119. This follows a near miss with a large piece of…

Risk assessment notes holddown post debris threat to shuttle
An assessment into the holddown post failure on STS-126’s launch has found that debris that is not captured by the Debris Containment System (DCS) is capable of impacting the vehicle during launch. A solution to STS-126’s anomaly is currently being certified for STS-119. The Holddown Post (HDP) #3 Debris Containment System (DCS) failure has already…
