|Mission: A multi-instrument airborne campaign to monitor the shallow reentry of ESA's 5th, and final, Automated Transfer Vehicle over the south Pacific ocean to better understand the physics of the end of life International Space Station de-orbit and the physics of shallow uncontrolled reentries.

February 20, 2015 - ESA said today that the breakup recorder that was inside ATV-5 during the reentry failed to transmit images from inside the vehicle during its breakup on February 15. [More]
February 15, 2015 - ATV-5 entered the Earth's atmosphere over the South Pacific ocean early this morning at 18:04 UT. [More]

February 12, 2015 - As a final effort to be prepared for the next shallow reentry opportunity, our team met at 4 am this morning to perform instrument checks, using calibration lamps at the far end of the darkened hangar. Later that morning the instruments and their racks were unloaded and readied for shipment home. It was a very sad moment to walk one last time through the DC8 aircraft, making sure nothing was left behind. The last item to collect was our mission logo sign at the bottom of the stairs.
February 11, 2015 - Our flight has been postponed. This morning, we investigated the possibility of performing a daytime reentry observation campaign to Tahiti on Sunday February 15. Jim calculated the new observation point and found it was not far from where we would have been on Feb 27, even closer to Tahiti. We made sufficient progress with the DC8 preparations to not have a significant show stopper there either.
However, the objective of the ATV5 Reentry Observation Campaign was to study the physics and dynamics of shallow reentries relevant to the ISS de-orbit and it was decided this morning that the remaining funds for such a study be better saved for a next observation attempt during a future controlled reentry of another (necessarily smaller) spacecraft. Those already arrived at AAOF are finishing work today and tomorrow to improve our instrument installations so we are ready for this next opportunity.
February 11, 2015 - Niel Murray of ESA reports that ESA's breakup recorder (BUC) was successfully installed on ATV5 by Samantha on Monday evening (GMT). Jack Bacon reports that NASA's REBR has been returned to the ISS and will be available for a future reentry.
February 10, 2015 - The shallow reentry was cancelled today. The ATV5 spacecraft had a power chain failure on February 3, which has forced ESA to reenter the vehicle immediately after undock on Saturday. For safety reasons, it would not be possible to execute a shallow reentry. ATV will be reentered on a steep trajectory Sunday February 15 during daytime.
February 10, 2015 - Images above show the TERAS install, the OMIT and AHI instrument fit-check at the window, and instrument principal investigator David Buttsworth, who arrived today from the University of Southern Queensland in Australia.
February 10, 2015 - NASA Armstrong conducted the Flight Readiness Review and Operational Readiness Review this morning. Pending the open items, such as completion of the instrument upload, the DC8 team and researchers are ready to observe the reentry. There are no remaining hurdles that can not be overcome, assuming the reentry happens as planned reachable from Tahiti in the morning of February 27. We are waiting for the final decision by ESA on when and how ATV-5 will be re-entered following the February 3 ATV5 power chain failure (one of four redundant systems).
February 9, 2015 - Today, we finally made some progress with the installation of TERAS, which will hopefully be completed tomorrow. Next up are the OMIT and AHI installations, with Ron Dantowitz as Instrument Principal Investigator. The Dexter Southfield team arrived from a snowy Boston this afternoon with about a third of their equipment in tow. Ron Dantowitz (foreground with telephone), Marek Kozubal and Forrest Gasdia (now at Embry-Riddle Aeronautical University) immediately started unpacking.
February 8, 2015 - Allocated funding has started to flow to the participating researchers and aircraft operators. Stefan Loehle reports that contract negotiations with ESA have been completed and ESA issued the first contract number for the ATV-5 Reentry Observation Campaign to the University of Stuttgart to support the mission science teams that will deploy onboard NASA's DC8. NASA supports the deployment of the aircraft in this ESA-NASA airborne observation campaign.
