Surprising insights about debris flows on Mars
The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice.
SpaceX scrubs Wednesday launch attempt at Kennedy Space Center
SpaceX scrubbed a launch attempt Wednesday night with just over 2 minutes on the countdown clock. The mission was set to send up another batch of Starlink satellites from the Space Coast using a first-stage booster for a record-tying 19th time.
Warm Jupiter exoplanet orbiting distant star detected
Astronomers report the discovery of a new warm Jupiter exoplanet orbiting a distant star in the open cluster Messier 67. The newfound extrasolar world, designated S1429 b, is almost twice as massive as Jupiter. The finding was detailed in a paper published March 5 on the pre-print server arXiv.
SpaceX poised for third launch test of Starship megarocket
SpaceX plans on Thursday to attempt another launch of Starship, the world's most powerful rocket that is vital to NASA's plans for landing astronauts on the moon later this decade--and Elon Musk's hopes of eventually colonizing Mars.
Evolved adapter for future NASA space launch system flights readied for testing
A test version of the universal stage adapter for NASA's more powerful version of its SLS (Space Launch System) rocket arrived at Building 4619 at NASA's Marshall Space Flight Center in Huntsville, Alabama, on Feb. 22 from Leidos in Decatur, Alabama. The universal stage adapter will connect the rocket's upgraded in-space propulsion stage, called the exploration upper stage, to NASA's Orion spacecraft as part of the evolved Block 1B configuration of the SLS rocket.
Unraveling the origins of life: Scientists discover 'cool' sugar acid formation in space
A critical molecule for the metabolism of living organisms has been synthesized for the first time by University of Hawai`i at Manoa researchers at low temperatures (10 K) on ice coated nanoparticles mimicking conditions in deep space, marking a "cool" step in advancing our understanding of the origins of life.
Do astronauts experience 'space headaches'?
Space travel and zero gravity can take a toll on the body. A new study has found that astronauts with no prior history of headaches may experience migraine and tension-type headaches during long-haul space flight, which includes more than 10 days in space. The study was published in Neurology.
