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. Polaris Dawn crew member and SpaceX engineer Sarah Gillis is seen during the first commercial spacewalk.

☆ SpaceX’s Polaris Dawn mission just made history. But the riskiest part is still to come

CNN —SpaceX’s Polaris Dawn mission kicked off early Tuesday, launching a four-person crew of civilian astronauts into orbit. The company confirmed that the SpaceX Crew Dragon spacecraft carrying the crew reached its peak altitude of 1,400.7 kilometers (870 miles) at 9:19 p.m. The Polaris Dawn mission also marks the farthest any human has journeyed since the final Apollo mission in 1972 — and the farthest into space a woman has ever traveled. The pre-breathe protocol the Polaris Dawn crew is undergoing is entirely unlike what is carried out on the International Space Station. In this screenshot from video, the Polaris Dawn crew sit in the Dragon capsule shortly after launching towards space on Tuesday.

☆ How the Columbia disaster changed the future of spaceflight

The CNN Original Series “Space Shuttle Columbia: The Final Flight” uncovers the events that ultimately led to disaster. The tragedy killed seven astronauts as the Columbia shuttle disintegrated upon its return to Earth on February 1, 2003, due to damage the vehicle sustained during launch. Changes at NASA were necessary, according to a formal investigation about the Columbia disaster published six months after the accident. Cultural changes: ‘Safety days,’ review boards and round tablesColumbia marked the second deadly mishap for the shuttle program after the space shuttle Challenger exploded during launch in January 1986. Following the Columbia disaster, NASA grounded its remaining fleet of three shuttles as the space agency sought to parse what went wrong.

☆ SpaceX Starship launch: Was it really a 'success?'
▼ + stars: | 2023-04-21 | by ( Jackie Wattles | ) edition.cnn.com time to read: +7 min

CNN —After the first test launch of a SpaceX Starship rocket — the most powerful launch vehicle ever constructed — ended in an eruption of flames over the Gulf of Mexico on Thursday, the company sought to frame the mission as a success. Within the space industry, Thursday’s Starship test mission wasn’t considered an outright failure, Caleb Henry, director of research at the space research firm Quilty Analytics, said. The SpaceX Starship exploded after launch for a flight test on April 20, 2023. There isn’t just one Starship vehicle that’s spent years in the development pipeline. The SpaceX rocket that flew on Thursday “was really just a bare bones,” Reisman added.

REUTERS/Joe SkipperLOS ANGELES, April 20 (Reuters) - The spectacular explosion of SpaceX's new Starship rocket minutes after it soared off its launch pad on a first flight test is the latest vivid illustration of a "successful failure" business formula that serves Elon Musk's company well, experts said on Thursday. PRACTICE MAKES PERFECTAt least two experts in aerospace engineering and planetary science who spoke with Reuters agreed that the test flight delivered benefits. "This is a classical SpaceX successful failure," said Garrett Reisman, an astronautical engineering professor at the University of Southern California who is a former NASA astronaut and is also a senior adviser to SpaceX. Reisman called the Starship test flight a hallmark of a SpaceX strategy that sets Musk's company apart from traditional aerospace companies and even NASA by "this embracing of failure when the consequences of failure are low." She said the risks of a single flight test were small in comparison to the ambitious gains at stake.
