Stream van 1200 kb/s is daar te vinden. Niet perfect maar veel beter dan die op de site van NASA.

NASA lanceert twee maansondes op 17 juni

Maansondes tegelijk De NASA zal op 17 juni twee onbemande sondes naar de Maan sturen, zo heeft het Amerikaanse ruimtevaartbureau bekendgemaakt. Het betreft de Lunar Reconnaissance Orbiter (LRO) en de Lunar Crater Observation and Sensing Satellite (LCROSS). Het is de bedoeling de twee Maanverkenners met een krachtige Atlas-V draagraket van Lockheed Martin te lanceren van op Cape Canaveral in Florida.


De LRO moet zoeken naar veilige landingsplaatsen, mogelijke bodemrijkdommen lokaliseren, de straling in kaart brengen en nieuwe technologie demonstreren. De sonde zal een jaar over de polen exploreren en dan een wetenschappelijke missie over verschillende jaren realiseren, zegt de NASA. LCROSS zal vier tot vijf maanden na lancering bewust op de Maan te pletter slaan, om zo baanbrekende informatie te vergaren omtrent de samenstelling van onze enige natuurlijke satelliet en de aanwezigheid te bepalen van water en van gehydrateerde mineralen.

Er zijn op 17 juni drie startmogelijkheden: 21.51, 22.01 en 22.11 uur Nederlandse tijd. Zo er een dag uitstel komt, zijn er op 18 juni gelegenheden om 23.12, 23.22 en 23.32 uur Nederlandse tijd.

STS-127 Launch Decision Expected Today

NASA managers are expected to make a final decision by this afternoon about whether to launch space shuttle Endeavour on Wednesday, June 17 or wait until later in the week.

Technicians at NASA's Kennedy Space Center continue to make progress as they work 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. Overnight, teams on Kennedy’s Launch Pad 39A completed changing out internal seals in the Ground Umbilical Carrier Plate, or GUCP, which is attached to the external tank. They’re now in the process of reattaching the vent line. The vent line runs from the GUCP, away from the launch pad to a "flare stack" where excess hydrogen is safely burned off. The reattachment is expected to be completed late tonight.

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.

NASA managers are looking to maximize launch opportunities this week for both the shuttle and the LRO/LCROSS missions. If there are no issues with Endeavour’s repair work, the shuttle would attempt to launch on June 17 and LRO/LCROSS would have launch opportunities on June 19 and 20. If Endeavour doesn’t launch on June 17 and LRO/LCROSS launches on that day, the shuttle could make a launch attempt on June 20.

Endeavour's leak is similar to what happened during the first launch attempt of space shuttle Discovery's STS-119 mission in March. Technicians are using the same repair method, which led to Discovery's successful launch on its next attempt.

Endeavour 'in Good Shape' for Wednesday Launch

At NASA's Kennedy Space Center in Florida, space shuttle Endeavour is set to launch on its STS-127 mission at 5:40 a.m. EDT Wednesday, June 17.

Endeavour's planned June 13 liftoff was postponed because of a leak associated with the gaseous hydrogen venting system outside the shuttle's external fuel tank. The system is used to carry excess hydrogen safely away from the launch pad. Technicians have removed and replaced the ground umbilical carrier panel and seal, and repair work should be complete by 3 p.m. Tuesday.

"Our teams have been working very hard over the last couple of days to get this piece of equipment fixed," said NASA Test Director Steve Payne during a briefing Monday afternoon. "Endeavour is in good shape and the teams are excited to be back to working toward a launch on Wednesday morning."

According to Shuttle Weather Officer Kathy Winters, the weather is expected to cooperate with NASA's launch plans, with an 80 percent chance of favorable weather expected.

Geen lek gevonden bij spaceshuttle Endeavour

CAPE CANAVERAL - De Amerikaanse ruimtevaartorganisatie NASA heeft de grote brandstoftank van de spaceshuttle Endeavour woensdag onderworpen aan een speciale test om te speuren naar lekken. Die werden niet gevonden, maakte de NASA bekend.

De lancering van de Endeavour moest vorige maand tot twee keer toe worden afgebroken omdat de tank waterstofdampen bleek te lekken.

Daardoor zou de spaceshuttle na de lancering kunnen ontploffen. Eerder dit jaar werd de lancering van een ander ruimteveer, de Discovery, om dezelfde reden enkele keren uitgesteld.

Derde poging
Op 11 juli wil de NASA een derde poging doen de Endeavour te lanceren. De zeven bemanningsleden brengen onder meer het laatste deel van een Japanse module naar het internationale ruimtestation ISS.

Careful Testing Under Way After Lightning Strikes

The launch of space shuttle Endeavour was postponed until Sunday evening so engineers could evaluate the spacecraft's myriad systems following 11 lightning strikes in the Launch Complex 39A area.

None of the strikes hit the shuttle or its external tank and solid rocket boosters, but there were strikes to the lightning mast and water tower. The launch pad is equipped with a lightning protection system of wires that is intended to steer bolts away from the shuttle.

"We've seen nothing so far that shows anything affected any of the systems," said Mike Moses, chairman of the pre-launch Mission Management Team.

Two of the strikes were strong enough to trigger an evaluation by engineers just to make sure all of Endeavour's systems are ready for flight. Although early evaluations showed no problems, engineers wanted more time to make sure they have checked everything correctly.

"We need to be 100 percent confident that we have a good system across the board," Moses said.

The launch time for Sunday is 7:13 p.m. EDT. The weather forecast calls for a 60 percent chance of acceptable conditions.
