The lengthy process of putting the retired space shuttle Endeavour on display in the vertical launch position will begin this month in Los Angeles.
The California Science Center announced Thursday that the six-month process will get underway July 20 at the future Samuel Oschin Air and Space Center currently under construction in Exposition Park.
The initial step, dubbed "Go for Stack," will be installation of the bottom portion of the solid rocket boosters known as aft skirts upon which will be stacked the booster segments, the external tank and then Endeavour.
The 20-story tall display will show the shuttle as it would appear waiting on a launch pad.
Endeavour was built as a replacement for the destroyed shuttle Challenger and flew 25 missions between 1992 and 2011.
When NASA's shuttles were retired, Endeavour was flown to California atop NASA's special Boeing 747 shuttle carrier in 2012, drawing crowds as it flew over locations in the state associated with the space program.
After landing at Los Angeles International Airport, the shuttle was placed on a special trailer and then created a sensation as it was inched through tight city streets to the California Science Center over several days.
Solving the RIME deployment mystery on ESA's Juice mission
When the RIME antenna on ESA's Juice mission failed to deploy a few days after launch, the engineering teams faced the mighty challenge of understanding the fault and rectifying it. At stake was a chance to see inside Jupiter's mysterious icy moons.
The stakes were already high before the spacecraft ever left the ground. ESA's Jupiter Icy Moons Explorer (Juice) was designed by Airbus to conduct an unprecedented investigation of the Jupiter system and its family of icy moons.
A key to that investigation is the Radar for Icy Moon Exploration (RIME) antenna, which is part of Juice's comprehensive suite of ten science instruments. Once in the Jupiter system, RIME will be used to remotely probe the subsurface of Jupiter's icy moons. Its radar signals will penetrate the moons to a depth of 9 km, and reveal details of between 50 and 140 m across. This will give insight into their geology and provide unique data to understand the habitability of these remote, icy moons.

Researchers propose new method to measure cosmic expansion
In 1929, astronomers discovered that galaxies are streaming away from us and each other. They interpreted this observation that the universe is expanding. However, when they measured how fast it is expanding, they got different answers using different methods. The difference continues to be a thorn in their description of the expanding universe.
A team of researchers led by Souvik Jana at Astronomers witness energetic switch on of black hole
A team of astronomers led by researchers from the University of Birmingham, University College London and Queen's University Belfast have discovered one of the most dramatic 'switches on' of a black hole ever seen. They will present their findings, Tuesday 4 July, at the 2023 National Astronomy Meeting in Cardiff. The work will also be published in Monthly Notices of the Royal Astronomical Socie Solving the RIME deployment mystery

Secrets of pearl harnessed for stronger space structures
Pearls and seashells are made from the same basic stuff as easily crushed chalk – humble calcium carbonate – so why are they so much tougher? Researchers are taking design tips from the micro-structure of these naturally formed materials to produce stronger, more fracture-resistant ceramics for future space missions.
Radio telescope observations confirm unintended radiation from large satellite constellations
Scientists use the LOFAR telescope to observe low-frequency radio waves from satellites in large constellations for the first time. "Unintended electromagnetic radiation" emanating from onboard electronics in Starlink satellites was detected which could impact astronomical research. Further study is now ongoing.
For a study published in the Astronomy and Astrophysics journal, scientists fr
