Hayley Arceneaux, a 29 year-old physician's assistant and childhood cancer survivor, today was named the second crew member for Inspiration4, which is set to be the first-ever all-civilian space flight.

Axios Re:Cap digs into the story behind the flight, Arceneaux's selection and what Inspiration4 means for the future of space tourism, with Axios Space editor Miriam Kramer.

When NASA's Perseverance rover landed on Mars Thursday, a set of cameras captured the car-sized spacecraft's descent and landing on the Red Planet.

Why it matters: This is the first time this type of high-quality footage has been captured.

Developers for COVID-19 therapeutics, vaccines and testing do not need to conduct large and lengthy clinical trials to address new coronavirus variants, new guidance from the Food and Drug Administration said Monday.

Why it matters: Mutated versions of the coronavirus threaten to prolong the pandemic, possibly for years to come — especially if current treatments are rendered less effective. The FDA's updated recommendations could greatly accelerate the emergency authorization process to address these concerns.

St. Jude physician assistant and childhood cancer survivor Hayley Arceneaux has been selected as the second crew member for an all-civilian mission to space expected to launch later this year.

Why it matters: The mission is a marker of a new age of commercial spaceflight, one in which private citizens and companies are able to go to space without government backing.

U.S. vaccine trials over the past decade have not included enough seniors and Hispanic and Black adults, and show a failure to report needed demographic details, according to a study published in JAMA Network Open Friday looking at a large sample of trials.

Why it matters: By not capturing a representative sample of Americans, vaccine trials cannot fully demonstrate the safety and effectiveness for all people and miss out on an opportunity to build trust within underrepresented communities — something vitally important in the COVID-19 pandemic, two experts tell Axios.

Fitbit started out trying to make us healthier by making us take a few extra steps. Now such wearables can help detect diseases like COVID-19 and even spot signs of depression, CEO James Park told "Axios on HBO."

The Federal Aviation Administration (FAA) said Sunday there must be "stepped up" inspections of Boeing 777 aircraft that contain the same engine model that failed on a United Airlines flight over Denver this weekend.

Why it matters: United, Japan's two main airlines and Korean Air have grounded Boeing 777s with the same Pratt & Whitney PW4000 engines as the jet involved in the Denver incident.

Officials in Texas announced Saturday investigations into the causes of the state's widespread power outages and an energy bills spike following the state's winter storms.

Why it matters: Millions of Texans lost power and water during last week's storms. In the aftermath, wholesale power prices rose from roughly $50 per megawatt hour to $9,000, WFAA reports — noting some Texans faced bills of up to $17,000 so far this month.
