Teams expected to access Endeavour by midday

Technicians at NASA Kennedy Space Center’s Launch Pad 39A have drained space shuttle Endeavour’s external fuel tank of more than 500,000 gallons of super cold liquid hydrogen and liquid oxygen. Excess fuel was boiled off and teams are ensuring any remaining hazardous gasses are vented out. Technicians expect to begin the processes of accessing Endeavour’s aft by midday, in order to look at a fuel line heater associated with the auxiliary power unit (APU) system, which caused a scrub of yesterday’s STS-134 launch attempt. APUs generate hydraulic power to throttle and gimbal main engines and move the aerosurfaces.

2011 MELGES 32 AUDI SAILING SERIES, SCARLINO ITALY – DAY 1

Melges32-Scarlino-Day 1 Max Ranchi

Consistency Sees Jason Carroll’s ‘Argo’ Lead After Three Races

The second regatta of the 2011 Melges 32 Audi Sailing Series at Marina di Scarlino, Maremma Tuscany, Italy, saw near perfect conditions prevail on Day 1. The twenty-two boat fleet, made up of teams from seven countries, was treated to three excellent races sailed in warm sunshine and a relatively steady 8 – 12 knot breeze. As ever at Melges 32 events, consistency was the order of the day, and the solid 6,1,2 scoreline posted by Jason Carroll and his Argo team from the USA, proved good enough to put him at the top of the leaderboard at the end of the first day. In second place lies fellow American John Kilroy on Samba Pa Ti. After comfortable second places the first two races, an uncharacteristic fourteenth place in the final race of the day leaves Kilroy six points adrift of Carroll. In third place is Britain’s Stuart Robinson on Highlife. Robinson’s steadily improving 10,7,1 score is all the more impressive given that today was his first ever day of Melges 32 racing.

NASA Resets Shuttle Endeavour’s Launch for No Earlier Than May 2

STS134-EndeavourAtPad

WASHINGTON — NASA managers met Friday to discuss the status of space shuttle Endeavour’s launch to the International Space Station. The launch was postponed because of a heater issue associated with the shuttle’s hydraulic power system. The next launch attempt will be no earlier than May 2.

The shuttle has three Auxiliary Power Units (APUs) that provide hydraulic power to steer the vehicle during ascent and entry. NASA launch commit criteria and flight rules require all three APUs to be fully operational for launch.

Endeavour’s external fuel tank was drained of more than 500,000 gallons of liquid hydrogen and oxygen so engineers can access the area Saturday and evaluate the issue with APU 1.

Engineers and Managers to Assess APU Issue

Fri, 29 Apr 2011 12:14:11 -0500

Shuttle launch director Mike Leinbach stated that Endeavour’s launch will be no earlier than Monday at 2:33 p.m. EDT. Engineers need that time to troubleshoot an issue that resulted in today’s launch scrub.

During today’s countdown, engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU) 1. Heaters are required to keep the APUs’ hydrazine from freezing on orbit. Attempts to activate the heater were not successful and engineers now believe the problem might be associated with a Load Control Assembly, which is a switchbox, located in the aft end of Endeavour, or an electrical short in the wires leading into or out of the switchbox.

Endeavour’s external tank will be drained, technicians will enter Endeavour’s aft compartment overnight and by tomorrow afternoon, will put in a platform to gain access to the avionics bay where the Load Control Assembly is located. Once there, they will assess whether they need to remove and replace the switchbox, or fix an electrical wiring short.

Because of this, Leinbach said there will be a minimum 72-hour scrub turnaround.

Engineers and managers will meet this afternoon to further refine their troubleshooting plan. NASA has scheduled a news conference at 4 p.m. to discuss today’s scrub and the plan.
