The AP reports that NASA announced Tuesday the Parker Solar Probe in April ¡°officially ¡®touched¡¯ the sun, plunging through the unexplored solar atmosphere known as the corona.¡± According to the AP, ¡°Scientists said it took a few months to get the data back and then several more months to confirm.¡±
CNN reports that the Parker Solar Probe ¡°made another intriguing encounter as it passed 6.5 million miles from the sun¡¯s surface. It passed through a feature called a pseudostreamer, a large structure rising above the surface of the sun that has been observed from Earth during solar eclipses.¡±

3) Daily Updates for NASA Artemis: News

Artemis I Successfully Completes Test Mission
The Washington Post (12/11) reports, ¡°NASA completed a significant step Sunday toward returning astronauts to the lunar surface with the successful completion of a test mission that sent a capsule designed for human spaceflight to orbit the moon and return safely to Earth.¡± NASA¡¯s unmanned Orion spacecraft ¡°splashed down in the Pacific Ocean off the Baja California peninsula of Mexico under a trio of billowing parachutes at 12:40 p.m. Eastern time.¡± The mission ¡°heralded, the space agency said, a series of upcoming missions that are to be piloted by a new generation of NASA astronauts as part of the Artemis program.¡±

https://www.washingtonpost.com/technology/2022/12/11/orion-splashdown-artemis-mission/

The New York Times (12/11) reports, ¡°During the 26 days of Artemis I, glitches popped up as expected, but the flight appeared to be devoid of major malfunctions that would require a lengthy investigation and redesign.¡± American Institute of Aeronautics and Astrnautics Executive Director Daniel L. Dumbacher said, ¡°It¡¯s a great demonstration that this stuff works.¡± According to the Times, ¡°Dumbacher oversaw early work on the Space Launch System more than a decade ago when he was a top human spaceflight official at NASA.¡± Further Artemis missions will aim to put astronauts back on the surface of the moon, facilitated by a SpaceX lander and Starships; ¡°for Artemis III, the lander will dock with the Orion spacecraft above the moon.¡± One of the three Starships ¡°will essentially serve as a gas station in orbit,¡± and while ¡°the idea of refueling in space dates back decades,¡± it ¡°remains largely untested.¡± Mr. Dumbacher said, ¡°Knowing what I think I know about the state of our research into microgravity propellant transfer, we have a long way to go.¡±

Space News (12/11, Subscription Publication) reports that following the conclusion of Artemis I, ¡°U.S. Space Command is using the mission to highlight its role in supporting NASA, even as the space agency considers alternatives to some of those services.¡± That branch of the military coordinated the recovery of the Orion spacecraft. U.S. Army Gen. James Dickinson ¡°said...that discussions have already started for the Artemis 2 crewed mission, scheduled for no earlier than late 2024.¡±

https://spacenews.com/space-command-promotes-role-in-artemis-1/

Space News (12/10, Subscription Publication) reported the European Space Agency ¡°praised the performance of the Orion spacecraft¡¯s service module, which some see as a step towards a European crewed spacecraft.¡± David Parker, ESA¡¯s director for human and robotic exploration, said, ¡°We are coming towards the end of what you might think of as a 100-meter race that¡¯s followed a marathon. The marathon was the 10 years of effort and preparation needed to build and prepare the first European Service Module for its journey to the moon and back again, and 100-meter race has been that actual mission itself.¡±

Spaceflight Now (12/9) reported, ¡°The mobile launch platform for NASA¡¯s Space Launch System moon rocket rolled back into the Vehicle Assembly Building at Kennedy Space Center Friday for inspections and repairs after liftoff of the Artemis 1 moon mission last month, setting the stage for upgrades to the 380-foot-tall structure before the first crewed Artemis moon flight scheduled for 2024.¡± Inspections have revealed the launcher incurred ¡°relatively minor damage¡± during the course of Artemis I¡¯s liftoff. While ¡°most of the damage was predicted,¡± NASA ¡°discovered the blast of the rocket¡¯s 8.8 million pounds of thrust blew the doors off elevators that run up and down the structure,¡± which ¡°wasn¡¯t expected¡± and could result in a longer repair time than initially thought.

NASA Administrator Bill Nelson appeared on CNN (12/9) ¡°to discuss what the next steps are for Artemis¡± following its successful first mission.
