NASA is ready to launch the “first step back to the Moon” - LRO/LCROSS - this afternoon. The unmanned probes will share a ride atop an Atlas V rocket from Cape Canaveral’s LC-41. NASA reports:

LRO, LCROSS at the Pad for Today’s Launch

Mission Overview
NASA’s Lunar Reconnaissance Orbiter and Lunar Crater Observation and Sensing Spacecraft will fly to the moon atop the same Atlas V rocket, although they will use vastly different methods to study the lunar environment. LRO will go into orbit around the moon, turning its suite of instruments towards the moon for thorough studies. The spacecraft also will be looking for potential landing sites for astronauts.

LCROSS, on the other hand, will guide an empty upper stage on a collision course with a permanently shaded crater in an effort to kick up evidence of water at the moon’s poles. LCROSS itself will also impact the lunar surface during its course of study.

Liftoff currently is scheduled for June 18 at 5:12 p.m. EDT. There are two more launch opportunities that day at 5:22 p.m. and 5:32 p.m.

After lightning delayed Shuttle Endeavour’s fueling by almost 3 hours, the old gaseous hydrogen leak issue surfaced again. Mission managers declared a scrub at 1:55 EDT this morning. NASA reports:

Endeavour Launch Now Targeted for July 11

Space shuttle Endeavour’s STS-127 second launch attempt was cancelled early Wednesday, June 17 due to a liquid hydrogen leak associated with the ground umbilical carrier panel. It’s the same location where a similar leak scrubbed Endeavour’s first launch attempt on June 13.

Endeavour’s next launch attempt is targeted for July 11 at 7:39 p.m. EDT.

It looks like 5:40AM Wednesday for Shuttle Endeavour’s liftoff to the International Space Station - if they can get her fueled up. Weather concerns have delayed the scheduled start of tanking, but mission managers have until about 10PM tonight to start loading the giant External Tank. NASA reports:

Endeavour ‘in Good Shape’ for Wednesday Launch

With the hydrogen leak repair scheduled for completion Tuesday afternoon, and some schedule shuffling for range clearance, Endeavour is now set for launch early (ugh!) Wednesday morning. The LRO/LCROSS moon mission will now launch Thursday at 5:12PM. NASA reports:

Endeavour, Crew to Launch June 17

NASA managers have scheduled the next launch attempt of Endeavour’s STS-127 mission for 5:40 a.m. EDT on Wednesday, June 17. The flight’s seven astronauts remain at NASA’s Kennedy Space Center in Florida.

Technicians at Kennedy are working to fix a leak associated with the gaseous hydrogen venting system outside Endeavour’s external fuel tank. The leak postponed Endeavour’s Saturday morning scheduled launch to the International Space Station. Teams on Kennedy’s Launch Pad 39A are in the process of changing out internal seals in the Ground Umbilical Carrier Plate, or GUCP, which is attached to the external tank. The vent line runs from the GUCP, away from the launch pad to a “flare stack” where excess hydrogen is safely burned off.

Ground personnel are working on the solution to the gaseous hydrogen leak that scrubbed Endeavour’s launch Saturday morning. Mission managers say the flight could go on as early as Wednesday, but that is the day that the LRO/LCROSS moon probes are scheduled to launch. NASA reports:

Launch Delayed for Endeavour and STS-127 Crew

Technicians at NASA’s Kennedy Space Center are working to fix a leak associated with the gaseous hydrogen venting system outside Endeavour’s external fuel tank. The leak postponed Endeavour’s Saturday morning scheduled launch to the International Space Station. Teams on Kennedy’s Launch Pad 39A are in the process of changing out internal seals in the Ground Umbilical Carrier Plate, or GUCP, which is attached to the external tank. The vent line runs from the GUCP, away from the launch pad to a “flare stack” where excess hydrogen is safely burned off.

Managers met Sunday afternoon to evaluate how repairs are going and assess when Endeavour’s next launch attempt will be. The earliest the shuttle could be ready for liftoff is June 17, however there is a conflict on that date with the scheduled launch of NASA’s Lunar Reconnaissance Orbiter/Lunar Crater Observation and Sensing Satellite from Cape Canaveral Air Force Station, Fla.

The 16-day mission will feature five spacewalks as the crews of Endeavour and the International Space Station work to install the Kibo Japanese Experiment Module Exposed Facility and Experiment Logistics Module Exposed Section on the orbiting outpost.

A hydrogen leak has forced a delay in Endeavour’s launch. We are looking at a minimum 4-day turnaround. Mission managers declared the scrub at 12:26AM EDT Saturday morning, before the crew had boarded. The issue is the same as the one that had delayed Discovery’s STS-119 launch in March. NASA reports:

Endeavour Launch Delayed

At NASA’s Kennedy Space Center in Florida, the launch of space shuttle Endeavour’s STS-127 mission to the International Space Station is on hold due to a leak associated with the gaseous hydrogen venting system outside the external fuel tank. The system is used to carry excess hydrogen safely away from the launch pad. At 12:26 a.m. EDT Saturday, June 13, shuttle managers officially scrubbed the launch for at least 96 hours.

Shuttle managers will meet Saturday morning to discuss what steps to take next, including targeting a new launch date.

The 16-day mission will feature five spacewalks as the crews of Endeavour and the International Space Station work to install the Kibo Japanese Experiment Module Exposed Facility and Experiment Logistics Module Exposed Section on the orbiting outpost.
