☆ Groundbreaking telescope reveals first piece of new cosmic map

Astronomers have never detected dark matter, but they believe it makes up about 85% of the total matter in the universe. Meanwhile, the existence of dark energy helps researchers explain why the universe is expanding — and why that expansion is speeding up. A prime example is the European Space Agency’s wide-angle Euclid telescope that launched in 2023 to investigate the riddles of dark energy and dark matter. Euclid this week delivered the first piece of a cosmic map — containing about 100 million stars and galaxies — that will take six years to create. These stunning 3D observations may help scientists see how dark matter warps light and curves space across galaxies.

The Crew Dragon capsule carrying four astronauts is on track to land off the coast of Dry Tortugas, Florida, at 3:36 a.m. Already, the Polaris Dawn mission has made history as it reached a higher altitude than any human has traveled in five decades. To safely reach home, the Crew Dragon capsule will carry out what’s called a “de-orbit burn,” orienting itself as it prepares to slice through the thickest part of Earth’s atmosphere. Polaris Dawn crew member and SpaceX engineer Sarah Gillis emerges from the Crew Dragon capsule's hatch on Thursday during the first commercial spacewalk. Sunday’s anticipated return will mark the conclusion of the third trip to space for the specific Crew Dragon capsule powering the Polaris Dawn mission.

CNN —SpaceX’s Polaris Dawn crew is beginning its fifth day in orbit, having marked a few record-setting milestones on a historic journey — including the world’s first commercial spacewalk. Polaris Dawn crew member and SpaceX engineer Sarah Gillis emerges from the SpaceX Crew Dragon capsule during the first commercial spacewalk on Thursday. The Polaris Dawn mission's Crew Dragon capsule is seen Wednesday 870 miles (1,400 kilometers) above Earth — the farthest humans have traveled since the Apollo program over 50 years ago. The riskiest part of the journey may be over, but the Polaris Dawn crew still has a key milestone ahead: coming home. Polaris Dawn mission commander and Shift4 Payments CEO Jared Isaacman is seen anchored to a ladder dubbed the "skywalker" by SpaceX during his spacewalk.

Inspiration4 mission commander Jared Isaacman stands for a portrait in front of a Falcon 9 rocket at SpaceX facilities in Hawthorne, California, in February 2021. The mission was meant to demonstrate that people from all walks of life can train for and execute a mission to orbit. I don’t know — it made me a real believer.”That’s why, Isaacman said, he worked with Musk and engineers at SpaceX to build the Polaris Program. Polaris Dawn is the first mission under that umbrella, with at least two more ventures to space planned for later down the road. The Polaris Program’s goal is to develop and test technologies that SpaceX would need if it established an extraterrestrial settlement.

Editor’s note: Relive the SpaceX Polaris Dawn historic commercial spacewalk as it happened. The Polaris Dawn crew can see a sunrise and sunset about every 106 minutes. Polaris Dawn crew members are seen within the SpaceX Crew Dragon capsule. Instead, the Polaris Dawn crew will receive their life support from long hoses attached to their spacecraft.
