NASA still aiming for 2020 first launch of SLS
SpaceNews.com (5/29): In briefings before the NASA Advisory Council’s Human Exploration and Operations Committee, NASA managers stress they are keeping alive a possible first test launch of the Space Launch System (SLS) and Orion capsule by the end of 2020. The uncrewed Artemis-1 mission would launch Orion around the Moon and back to Earth. Once planned for mid-2020, Artemis 1 flight faces SLS core stage development and pre-launch test challenges. The third in the series of SLS/Orion test flights is to place human explorers on the surface of the Moon in 2024.

Without a champion, Europa lander falls to NASA’s back burner
Sciencemag.org (5/29): Despite early political and funding support from Congress, a challenging NASA mission intended to investigate whether Europa, the ice and ocean covered moon of Jupiter, hosts a habitable environment, faces significant technical and cost challenges that could disrupt other planetary science missions assigned a high priority, according to an audit by the space agency’s inspector general.

A new view of exoplanets with NASA’s upcoming Webb Telescope
NASA/Goddard Space Flight Center (5/29): NASA is preparing the James Webb Space Telescope (JWST) for a 2021 launch, as a successor to the Hubble Space Telescope. One of Webb’s assignments is to look close at recent extra solar planet discoveries for signs of biomarkers, or atmospheric evidence of habitable environments on distant worlds.

China’s first Mars spacecraft undergoing integration for 2020 launch
SpaceNews.com (5/29): China plans to join NASA and a European/Russian partnership in launching independent landers and rovers to Mars in mid-2020, timing that marks a favorable alignment between the Earth and the Red Planet. China plans an orbiter and a rover, which will be equipped with a ground penetrating radar and environmental sensors. China has two landing sites are under evaluation, one in the neighborhood of NASA’s Viking 1 and Pathfinder mission lander and rover of old, and a second near where NASA’s Curiosity rover is currently exploring.
