This graphic shows the route that NASA's Mars Exploration Rover Opportunity drove in its final approach to 'Perseverance Valley' on the western rim of Endeavour Crater. The map covers an area about four-tenths of a mile (two-thirds of a kilometer) wide, with the interior of the crater on the right. Opportunity entered this mapped area from the north along the gold traverse line on March 21, 2017, approaching the southern tip of the "Cape Tribulation" segment of Endeavour's rim. It reached the top of "Perseverance Valley" with a drive on Sol 4720 (the 4,720th Martian day) of the mission, on May 4, 2017. https://photojournal.jpl.nasa.gov/catalog/PIA21496
Wheels are installed on NASA’s Mars Perseverance rover inside Kennedy Space Center’s Payload Hazardous Servicing Facility on March 30, 2020. Perseverance will liftoff aboard a United Launch Alliance Atlas V 541 rocket from Cape Canaveral Air Force Station in July 2020. NASA’s Launch Services Program based at Kennedy is managing the launch. The rover will land on Mars on Feb. 18, 2021.

Credits: NASA/Chris Gunn More: Since December 2015, the team of scientists and engineers have been working tirelessly to install all the primary mirror segments onto the telescope structure in the large clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The twelfth mirror was installed on January 2, 2016. "This milestone signifies that all of the hexagonal shaped mirrors on the fixed central section of the telescope structure are installed and only the 3 mirrors on each wing are left for installation," said Lee Feinberg, NASA's Optical Telescope Element Manager at NASA Goddard. "The incredibly skilled and dedicated team assembling the telescope continues to find ways to do things faster and more efficiently." Each hexagonal-shaped segment measures just over 4.2 feet (1.3 meters) across and weighs approximately 88 pounds (40 kilograms). After being pieced together, the 18 primary mirror segments will work together as one large 21.3-foot (6.5-meter) mirror. The primary mirror will unfold and adjust to shape after launch. The mirrors are made of ultra-lightweight beryllium. The mirrors are placed on the telescope's backplane using a robotic arm, guided by engineers. The full installation is expected to be completed in a few months. The mirrors were built by Ball Aerospace & Technologies Corp., Boulder, Colorado. Ball is the principal subcontractor to Northrop Grumman for the optical technology and lightweight mirror system. The installation of the mirrors onto the telescope structure is performed by Harris Corporation of Rochester, New York. Harris Corporation leads integration and testing for the telescope. While the mirror assembly is a very significant milestone, there are many more steps involved in assembling the Webb telescope. The primary mirror and the tennis-court-sized sunshield are the largest and most visible components of the Webb telescope. However, there are four smaller components that are less visible, yet critical. The instruments that will fly aboard Webb - cameras and spectrographs with detectors able to record extremely faint signals — are part of the Integrated Science Instrument Module (ISIM), which is currently undergoing its final cryogenic vacuum test and will be integrated with the mirror later this year.
