Hope is the first interplanetary mission from the UAE and the Arab world. Spacecraft from three nations were launched toward Mars in July: United Arab Emirates’ Hope orbiter China’s Tianwen-1 orbiter and the lander and rover it will release toward the surface and NASA’s Perseverance rover with the Ingenuity helicopter. The review will inform a down selection to compete for the 2024 landing opportunity. As of late October, NASA was reviewing the details of the proposals to determine that they meet the Human Landing System requirements ahead of the Continuation Review scheduled for December 2020. In April, NASA announced the selection of Blue Origin, Dynetics and SpaceX to compete to land the first woman and the next man on the moon in the first of NASA’s planned series of Artemis lunar missions. ![]() The spacecraft completed 33 revolutions, testing onboard equipment, before landing at White Sands Missile Range in New Mexico. Boeing, the second Commercial Crew provider, worked on assembling the Starliner crew and service modules for its next uncrewed launch, after an uncrewed Starliner could not reach the station last December due to an issue with the mission clock. The Demo-2 mission marked final certification of the Dragon design, and cleared the way for the November launch of the Crew-1 operational mission. Design engineers carried out these simulations whereas typically the operations staff are a different group. ![]() SpaceX utilized an innovative approach to the mission design by relying on ground-based simulations to determine where significant events and phases should start and end. In space transportation, the uncrewed SpaceX Dragon In-Flight Abort Test in January verified performance of the Super Draco abort engines, clearing the way for the May launch of astronauts Bob Behnken and Doug Hurley to the International Space Station in the Demo-2 mission. DARPA has equipped the demonstration vehicles with parachutes for purposes of the test flights, but operational versions would not require recovery parachutes. The first Gremlin flight, in November 2019, met its test objective of proving the aircraft could be released from the wing of a C-130, but the vehicle crashed at the conclusion of the test when its main parachute did not deploy. In July, a Gremlin vehicle flew in formation with a C-130, approaching to within 38 meters of the C-130 before parachuting to the ground. The FAA in November lifted the grounding order so airlines could begin the changes to software and pilot training required to clear the planes to resume commercial service.Īs of November, DARPA was working to resume flights over the Utah desert with one of the four remaining Dynetics-built X-61A Gremlin Air Vehicles, the objective for this round being to grasp and hoist a Gremlin onto a C-130, followed by two Gremlins on a subsequent flight. Boeing resumed production of 737 MAX aircraft in May and in June conducted recertification flight tests after design changes. The jets were grounded worldwide in March 2019 following the second fatal crash in a span of four months. The FAA in November lifted the grounding order on the Boeing 737 MAX aircraft so airlines can begin making the changes to software and pilot training required to clear the planes to resume commercial service. ![]() The Atmospheric Flight Mechanics Technical Committee addresses the aerodynamic performance, trajectories and attitude dynamics of aircraft, spacecraft, boosters and entry vehicles.
