NASA officials gave an update Thursday on the status of the Artemis I moon rocket launch saying it likely is targeting early- to mid-June before it rolls back out to the launch pad for a wet dress rehearsal at Kennedy Space Center.

NASA Administrator Bill Nelson suggested last week that August would be the earliest for a launch attempt, and NASA's Jim Free, the associate administrator for the Exploration Systems Development Mission Directorate, confirmed that.

"As we've been saying, we'll set that official launch date after we get through wet dress," Free said. "But you know based on some of historical challenges from similar programs over the years and the schedule performance we've seen thus far, we are looking at a couple of launch periods through the August time frame."

One of the previously announced launch windows runs from July 26 to Aug. 9.

NASA rolled the Space Launch System rocket topped with the Orion spacecraft to KSC's Launch Pad 39-B back in mid-March and attempted to run through a simulated countdown along with the filling and draining the core and upper stages with 730,000 gallons of super-cooled liquid hydrogen and liquid oxygen.

Approximately a month before it begins its research flight in the stratosphere, the balloon-borne solar observatory Sunrise III has looked at the Sun for the first time from its launch site at the Arctic Circle. In June, Sunrise III will take off from Esrange Space Center, the Swedish Space Agency's (SSC) balloon and rocket base in Kiruna (Sweden), and will climb to an altitude of about 35 kilometers. During its flight of several days, it will then take unique measurements of the Sun. In this way, processes in the chromosphere, the highly dynamic layer between the visible surface and the outer atmosphere of the Sun, will become visible more precisely than ever before. In the remaining weeks until launch, the technical and scientific teams from Germany, Spain, Japan, and the U.S. will prepare all systems and the scientific instruments for their mission and rehearse flight procedures and operations.

SpaceX brought four astronauts home with a midnight splashdown in the Gulf of Mexico on Friday, capping the busiest month yet for Elon Musk's taxi service.

Humans have long dreamed of setting foot on Mars or beyond, and the advances by companies like SpaceX and Blue Origin means perhaps the dream could be closer than ever to becoming reality. But as it stands now, sending astronauts on long-duration missions to other worlds would be impossible because of the hazardous radiation levels in space, outside of Earth's protective magnetic field.

However, a new concept offers hope on the horizon, and the researchers behind it have received funding from the NASA Innovative Advanced Concepts (NIAC) program to build a prototype. Called CREW HaT, the proposal takes advantage of the latest advances in superconducting magnet technology to effectively shield spacecraft—and the astronauts inside—from harmful space radiation.

"We came up with a novel idea about how to shield spaceships from cosmic radiation and energetic solar radiation," said Dr.
