NASA's 1st Manned Flight of Orion Space Capsule May Slip to 2023

The first manned flight of NASA's Orion spacecraft, which is being built to help humanity explore Mars and other distant destinations, may be delayed by two years, until 2023, agency officials announced today. Orion's first crewed sojourn, known as Exploration Mission 2 (EM-2), is officially targeted for launch in August 2021. Engineers and technicians are still working toward the August 2021 goal, but hitting that target is unlikely, said NASA Associate Administrator Robert Lightfoot.

NASA's Curiosity Rover Finds Petrified Sand Dunes on Mars (Photo)

A sweeping new panorama from NASA's Curiosity rover shows petrified sand dunes stretching across the jagged terrain of Mount Sharp on Mars. Curiosity's science team says the newly imaged dunes look similar to "crossbedding," structures formed by wind-deposited sand dunes such as those in the U.S. southwest. By looking at the sand dunes' geometry and orientation, scientists can get information about the winds that created the dunes.

An Ocean Flows Under Saturn's Icy Moon Enceladus

Saturn's moon Enceladus is an active water world with a global body of water sloshing around deep below its icy crust, scientists have confirmed. The smoking gun is the very slight wobble that Enceladus displays as it orbits Saturn. Instead, the moon must contain a complete ocean layer, according to new research that relied on more than seven years of images taken by NASA's Cassini space probe.

First manned test flight of new deep-space capsule likely delayed: NASA

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - The first manned test flight of NASA's new deep-space Orion capsule faces a likely two-year-year delay until 2023 due to development and budget concerns, officials with the U.S. space agency said on Wednesday. The capsule, along with its multibillion-dollar heavy lift launcher, are the most expensive parts of a long-term U.S. human space exploration initiative leading toward a crew landing on Mars in the mid-2030s. NASA had been aiming for its first crew test flight of Orion in August 2021.

Whoa! Sun-Watching Spacecraft Finds 3,000th Comet

A spacecraft that launched in 1995 to study the sun has discovered its 3,000th comet, further bolstering its credentials as history's greatest comet hunter. The Solar and Heliospheric Observatory (SOHO), a joint effort of NASA and the European Space Agency (ESA), spotted comet number 3,000 on Sunday (Sept. 13). The landmark discovery was pulled out of SOHO's database by Worachate Boonplod of Thailand, NASA officials said.

'The Martian' Lands at NASA: Actors Meet Real-Life Counterparts in Houston

Sebastian Stan and Mackenzie Davis visited the agency's Johnson Space Center in Houston, where the actors met with their characters' real-life counterparts, took a spin in a prototype rover and spoke with the astronauts aboard the International Space Station. The day was capped by a preview screening of the Ridley Scott-directed film, which opens in theaters on Oct. 2. "I think you can go back and tell the other cast members that you got closer to Mars than any of them have done," said Ellen Ochoa, a shuttle-era astronaut and the director of the Johnson Space Center, referencing Stan and Davis' visit and a Martian meteorite brought out for display.

Some Apollo Moon Samples 'Crumbling to Dust'

Some of the moon soil collected by Apollo astronauts has deteriorated significantly during its four-plus decades on Earth, a new study reports. Scientists found that the median particle size in a set of 20 different Apollo soil samples held in laboratories for research use has decreased by more than half since the samples were first measured 40 years ago. "It might be accurate to state that the Apollo lunar soils are literally crumbling to dust," the scientists, led by Bonnie Cooper of Hanyang University in South Korea, wrote in the new study.

Flower Power: Giant 'Starshades' Prepped for Exoplanet Hunting

"The unique architecture of the starshade — namely, the size and separation needed — make it difficult to test cheaply," Anthony Harness, a graduate student at the University of Colorado, Boulder, told Space.com. Harness works with Tiffany Glassman and Steve Warwick, of the aerospace company Northrop Grumman, to test starshades on Earth in dry lake beds and on mountaintops. Harness presented some of the test results at the Emerging Researchers in Exoplanet Science (ERES) Symposium at Pennsylvania State University in April.

Energy Drinks Tied to Brain Injuries in Teens

Teens who drink energy drinks a lot are more likely to get head injuries than those who don't consume the highly caffeinated beverages, a new study from Canada suggests. Students were asked about their energy drink consumption, as well as whether they had experienced a traumatic brain injury (TBI), meaning they had sustained a blow to the head that left them unconscious for at least 5 minutes, or resulted in an overnight hospital stay. About 22 percent of students said they had experienced a traumatic brain injury (TBI) in their lifetimes, and 6 percent said they'd had a TBI in the last year.

Caffeine Confuses Your Body's Internal Clock, Study Suggests

Drinking a cup of coffee at night may mess up your sleep in more ways than one: Caffeine not only keeps you awake but also affects your body's internal clock, which tells you when it's time to sleep and wake up, a new study suggests. The finding shows that caffeine "affects our physiology in a way that we hadn't really considered in the past," said Kenneth P. Wright Jr., a co-author of the study and director of the Sleep and Chronobiology Laboratory at the University of Colorado. In the study, five healthy people spent a night in a laboratory, where researchers monitored their levels of melatonin, a hormone that increases at night and is an indicator of the body's internal clock, also known as circadian rhythm.
