The quantity of fentanyl seized by Customs and Border Protection agents along the U.S.-Mexico border has increased from 2,633 pounds in fiscal year 2019 to 10,586 pounds two years later, and to 14,104 pounds in FY 2022. Using six motors that deploy each segment approximately half the length of a paper clip, these actuators clear the mirrors from their launch restraints and give each segment enough space to later be adjusted in other directions to the optical starting position for the upcoming wavefront alignment process. The team also commanded actuators that guide Webbs fine steering mirror to make minor movements, confirming they are working as expected. during 2021's two lunar eclipses. Therefore, Webb requested just enough energy from the Ariane rocket to ensure that we would never have to do a retro burn, but would always require a burn from the observatory to precisely make up the difference and place it in the desired orbit. After two weeks of complex structural deployments, Webb has passed a major milestone and is now fully unfolded in space. After revealing a trove of details about the moons Ganymede and Europa, the mission to Jupiter is setting its sights on sister moon Io. Saturn's two-faced moon tilts and rotates for Cassini in this mesmerizing movie sequence of images acquired during the spacecraft's close encounter with Iapetus on Nov. 12, 2005. So, why did the Ariane not give Webb more energy and why did Webb need course correction? Comets are typically brightest around perihelion, and the . Ground teams have now begun instructing the primary mirror segments and secondary mirror to move from their stowed-for-launch configuration, off of snubbers that kept them snug and safe from rattling from vibration. } New year, new Moon; midnight meteors; and Mars rises. Comet Leonard will round the sun at perihelion on January 3, 2022, at a distance of about 56 million miles (0.6 AU, or 90 million km). Well be updating it.
