A year ago they weren't even certain it could be done, but now they're increasingly confident."We've looked at most of the things that used to really bother us," said Dara Sabahi, a lead engineer on the project. "There were a lot of gotchas, but today I can say that — and I don't say this lightly — we are confident we can make this work. I believe the technologies are in reach, and the risks that bothered us are manageable."...during the briefings at JPL, Culberson brought a friend with him, the famed Director James Cameron. The two men share an interest in exploring the depths of oceans, and periodically Cameron peppered the JPL presenters with questions about batteries, the chemistry of Europa's ocean, and so forth. But mostly, he came as Europa's storyteller-in-chief. "If you want to talk to the world, this man knows how to do it," Culberson said of his friend.</BLOCKQUOTE></TD></TR><TR bgcolor="#494949"><TD valign=top>Robert Pearlman</TD><TD>From NASA <A HREF="https://twitter.com/NASAEuropa" TARGET=_blank>on Twitter</A>: <BLOCKQUOTE>It's official!

The fiscal year 2019 appropriations bill required that the mission launch by 2023 on an SLS."[W]e urge Congress to consider removing the requirement that NASA launch the Europa Clipper on an SLS and allow the Agency to decide whether to use an SLS or a commercial vehicle based on cost, schedule, vehicle availability, and impact on science requirements," he added.</BLOCKQUOTE></TD></TR><TR bgcolor="#333333"><TD valign=top>Robert Pearlman</TD><TD>The U.S. House of Representatives Appropriations Committee <A HREF="https://appropriations.house.gov/news/press-releases/appropriations-committee-releases-fiscal-year-2021-commerce-justice-science" TARGET=_blank>today released</A> its draft fiscal year 2021 Commerce, Justice, Science, and Related Agencies funding bill, which includes NASA.

Hurricane Milton is expected to move from the Gulf of Mexico this week moving east to the Space Coast. High winds and heavy rain are expected in the Cape Canaveral and Merritt Island regions on Florida's east coast. Launch teams have secured NASA's Europa Clipper spacecraft in SpaceX's hangar at Launch Complex 39A at the agency's Kennedy Space Center in Florida ahead of the severe weather, and the center began hurricane preparations Sunday."The safety of launch team personnel is our highest priority, and all precautions will be taken to protect the Europa Clipper spacecraft," said Tim Dunn, senior launch director at NASA's Launch Services Program.On Oct. 4, workers transported NASA's Europa Clipper spacecraft from the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center to the SpaceX Falcon Heavy rocket in the hangar as part of final launch preparations ahead of its journey to Jupiter's icy moon. While Europa Clipper's launch period opens Oct. 10, the window provides launch opportunities until Wednesday, Nov. 6.Once the storm passes, recovery teams will assess the safety of the spaceport before personnel return to work. Then launch teams will assess the launch processing facilities for damage from the storm."Once we have the 'all-clear' followed by facility assessment and any recovery actions, we will determine the next launch opportunity for this NASA flagship mission," said Dunn.</blockquote></TD></TR><TR bgcolor="#333333"><TD valign=top>Robert Pearlman</TD><TD>The Europa Clipper launch team is working to protect launch opportunities for no earlier than Sunday, Oct. 13 through Wednesday, Nov. 6.</TD></TR><TR bgcolor="#494949"><TD valign=top>Robert Pearlman</TD><TD>NASA update <BLOCKQUOTE>NASA and SpaceX are now targeting no earlier than Monday, Oct. 14, for the launch of Europa Clipper.

Next stop, Mars.

Europa Clipper is set to arrive at the red planet on March 1, 2025 for a gravity assist, sending it back towards to Earth for another slingshot maneuver before heading outwards to Jupiter for an April 11, 2030 arrival.
