SpaceX Capsule Splashes Down Off Florida After Intentional Rocket Failure Test

New Census Data Gives Hope Decline of Kids Living with Both Parents Has Bottomed Out

WASHINGTON—U.S. Census Bureau data shows that, while slightly more than 60 percent of American children live with their biological or adoptive parents, the downward trendline has flattened out and may be heading in a positive direction, according to the Institute for Family Studies (IFS). “As recently as 1960, less than two in 10 children lived apart from two married parents, a reality which was approximately stable as far back as 1850,” according to IFS Research Fellow Lyman Stone, author of the new study that was published Jan. 15. “But while the present situation leaves many children bereft of the care, attention, and material benefits of a married household, it’s actually not as bad as it has been in the past,” Stone writes, noting that “since 2014, the share of children…

SpaceX Capsule Splashes Down Off Florida After Intentional Rocket Failure Test

CAPE CANAVERAL, Fla.—Elon Musk’s SpaceX simulated a successful emergency landing on Sunday in a dramatic test of a crucial abort system on an unmanned astronaut capsule, laying the foundation for its mission to fly NASA astronauts for the first time.

A Crew Dragon astronaut capsule launched at 10:30 a.m. local time and softly splashed down about 19 miles (32 km) off the coast of Cape Canaveral in Florida roughly eight minutes later, after ejecting itself from a rocket that cut off its engines 12 miles (19 km) above the ocean to mimic a launch failure.

National Aeronautics and Space Administration administrator Jim Bridenstine called the mission a success.

“This critical test puts us on the cusp of once again launching American astronauts on American rockets from American soil,” Bridenstine wrote on Twitter. “Spacecraft recovery operations are underway.”

In a key trial for carrying humans, SpaceX was also testing its rescue teams’ response after splashdown. They scrambled toward Crew Dragon with the U.S. Air Force’s Detachment 3 emergency rescue teams in tow—a vital part of the test to practice a rescue mission to retrieve astronauts from the capsule.

Moments before the launch, Musk wrote on Twitter that it was a risky mission that was “pushing the envelope in so many ways”.

The Crew Dragon capsule, an acorn-shaped pod that can seat seven astronauts, fired onboard thrusters to detach itself from a Falcon 9 rocket less than two minutes after liftoff, simulating an emergency abort scenario to prove it can return astronauts to safety. Each stage of the test prompted loud cheers from SpaceX crew members watching the footage from back on land.

The test is crucial to qualify the capsule to fly humans to the International Space Station, something NASA expects to come as soon as mid-2020. It follows years of development and delays as the United States has sought to revive its human spaceflight program through private partnerships.

NASA awarded $4.2 billion to Boeing and $2.5 billion to SpaceX in 2014 to develop separate capsule systems capable of ferrying astronauts to the space station from U.S. soil for the first time since NASA’s space shuttle program ended in 2011. The space agency has since relied on Russian spacecraft for rides to the space station.

During the test the Falcon 9 rocket’s boosters shut down in a mock failure that triggered Crew Dragon’s so-called SuperDraco thrusters to jet itself away at supersonic speeds of up to 1,500 miles per hour (2,400 kph). The Falcon 9 booster free-fell back to the ocean, with its first stage crashing into the ocean creating a tall plume of smoke seen on the horizon.

The capsule deployed four parachutes to slow its descent to the water, and carried two human-shaped test dummies on seats fitted with motion sensors to collect data on the immense g-force—the effect of acceleration on the body—astronauts would be subjected to during abort.

The test was originally scheduled for mid-2019 but was delayed after a Crew Dragon capsule exploded in April on a test stand just before firing its launch abort thrusters, triggering a lengthy investigation.

SpaceX-led investigators in July zeroed in on a previously unknown explosive reaction between a titanium valve and a propellant used to ignite the thrusters. A SpaceX official said the company completed the investigation within the last week.

Boeing Grapples With New Software Snag on 737 MAX

Boeing said it is fixing a new software snag found last weekend during a technical review of the proposed update to the grounded Boeing 737 MAX. “We are making necessary updates and working with the Federal Aviation Authority (FAA) on submission of this change, and keeping our customers and suppliers informed,” Boeing said in a statement. “Our highest priority is ensuring the 737 MAX is safe and meets all regulatory requirements before it returns to service.” Company officials said the issue relates to a software power-up monitoring function that verifies some system monitors are operating correctly. Boeing has halted production of the 737 MAX this month following the grounding in March of its best-selling plane after two fatal crashes in five months killed 346 people. The company has been in…
