for NASA. Masten Space Systems Masten Space Systems Inc. of Mojave, Calif. is believed to have bid both the XEUS lander and the smaller XL-1 lander. XEUS comes in two versions. The expendable version can land about , where as the reusable version can land . Masten has signed an unfunded Space Act Agreement with NASA containing 22 Milestones to demonstrate the hardware and software for a commercial lunar lander, ending in August 2017. Milestone 16: Drop test of landing gear components has been completed. The XL-1 is being designed to soft land a payload of on the lunar surface. The 2-year extension to the NASA/Masten SAA signed September 27, 2017 has a total of 32 milestones. The additional milestones cover XL-1, XL-1T and the XEUS concept. On November 29, 2018 Masten was awarded a Commercial Lunar Payload Services contract by NASA, which makes it eligible to bid on delivering science and technology payloads to the Moon for NASA. The landing will be no earlier than 2021. Moon Express Moon Express Inc., of Moffett Field, Calif. is believed to have bid the MX-1 lander family. In early 2015 Moon Express test flew a tethered prototype lander at the Morpheus Lander test area at NASA's Kennedy Space Center as part of its entry in the Google XPRIZE. The operational spacecraft is designed to be launched as a secondary payload and to fly to the Moon from GEO. Moon Express has signed a 5-year agreement with Space Florida to perform lunar lander development and flight test operations at Space Launch Complex 36 (SLC-36), Cape Canaveral Air Force Station in Brevard County, Florida. Moon Express hopes to soft land on the Moon in 2016. The MX-1 will exit Low Earth Orbit using its hydrogen peroxide engine. Later missions plan to bring back to Earth minerals, Moon rocks and precious metals. The unfunded Space Act Agreement (SAA) with NASA contains 16 milestones ending in March 2017. the lander's tether test has been completed. On September 26, 2017 Moon Express signed an extension to its SAA with NASA lasting until September 2019. Moon Express has completed Milestone 6: MX-1 System design review. There are 17 further milestones. On November 29, 2018 Moon Express was awarded a Commercial Lunar Payload Services contract by NASA, which makes it eligible to bid on delivering science and technology payloads to the Moon for NASA.
