NASA's upcoming space telescope, the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, or SPHEREx, is one step closer to launch. The mission has officially entered Phase C, in NASA lingo. That means the agency has approved preliminary design plans for the observatory, and work can begin on creating a final, detailed design, as well as on building the ha Deep Dive into a Galaxy Cluster

Astronomers refer to observations as "deep" when they are taken with very long exposure times. Just as with photography, this gathers more light, revealing distant, fainter objects. Deeper exposures let astronomers look deeper into the Universe - hence the name. This particular deep image was taken with a 70-minute exposure with the Nicholas U.

Sea ice is a critical indicator of changes in the Earth's climate. A new discovery by Brown University researchers could provide scientists a new way to reconstruct sea ice abundance and distribution information from the ancient past, which could aid in understanding human-induced climate change happening now.

NASA's first mission to the Trojan asteroids integrates its second scientific instrument
Monday, 04 January 2021 21:07 Write a comment
NASA's Lucy mission is one step closer to launch as L'TES, the Lucy Thermal Emission Spectrometer, has been successfully integrated on to the spacecraft.
"Having two of the three instruments integrated onto the spacecraft is an exciting milestone," said Donya Douglas-Bradshaw, Lucy project manager from NASA's Goddard Space Flight Center in Greenbelt, Maryland. "The L'TES team is to be commended for their true dedication and determination."
Lucy will be the first space mission to study the Trojan asteroids, leftover building blocks of the Solar System's outer planets orbiting the Sun at the distance of Jupiter. The mission takes its name from the fossilized human ancestor (called "Lucy" by her discoverers) whose skeleton provided unique insight into humanity's evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the birth of our solar system more than 4 billion years ago.
L'TES, developed by a team at Arizona State University (ASU), is effectively a remote thermometer.
Delta Air Lines adds Viasat in-flight connectivity service

SAN FRANCISCO – Delta Air Lines announced plans Jan. 5 to turn to Viasat for in-flight Ka-band connectivity for passengers flying in more than 300 of the carrier’s mainline narrow-body aircraft.
The announcement, which Delta says will lay the groundwork to make in-flight internet fast and free, covers new deliveries and retrofits of Airbus A321ceo, Boeing 737-900ER and select Boeing 757-200 aircraft.
Remote sensing data sheds light on when and how asteroid Ryugu lost its water
Monday, 04 January 2021 17:43 Write a comment
Last month, Japan's Hayabusa2 mission brought home a cache of rocks collected from a near-Earth asteroid called Ryugu. While analysis of those returned samples is just getting underway, researchers are using data from the spacecraft's other instruments to reveal new details about the asteroid's past.
In a study published in Nature Astronomy, researchers offer an explanation for why Ryugu isn't quite as rich in water-bearing minerals as some other asteroids. The study suggests that the ancient parent body from which Ryugu was formed had likely dried out in some kind of heating event before Ryugu came into being, which left Ryugu itself drier than expected.

SAN FRANCISCO – AAC Clyde Space subsidiary Hyperion Technologies won a 150,000 euro ($185,000) contract to perform an in-orbit verification flight for CubeCAT, the company’s small satellite laser communications terminal.
Hyperion announced plans Jan. 5 to launch CubeCAT in early 2022 onboard NorSat-TD, a technology demonstration mission coordinated by the Norwegian Space Agency.

NASA astronaut Mike Hopkins performs the Grasp experiment in the Columbus module of the International Space Station ahead of the New Year. The experiment studies how the central nervous system, specifically hand-eye coordination, adapts to microgravity.
Grasp stands for Gravitational References for Sensimotor Performance and seeks to better understand how the central nervous system integrates information from different senses, such as sight, sound and touch, to coordinate hand movements and determine what role gravity plays.
How does the experiment work? Mike dons virtual reality (VR) gear that is coupled with a laptop and driven by an audio/graphics system. The VR

Making methane on Mars
Monday, 04 January 2021 12:56 Write a comment
Among the many challenges with a Mars voyage, one of the most pressing is: How can you get enough fuel for the spacecraft to fly back to Earth?
Houlin Xin, an assistant professor in physics & astronomy, may have found a solution.
He and his team have discovered a more efficient way of creating methane-based rocket fuel theoretically on the surface of Mars, which can make the return trip all more feasible.
The novel discovery comes in the form of a single-atom zinc catalyst that will synthesize the current two-step process into a single-step reaction using a more compact and portable device.

WASHINGTON — SpinLaunch expects to perform the first suborbital tests of a prototype of its centrifugal system for launching small satellites later this year from New Mexico.
The company, based in Long Beach, California, has said little about its efforts to develop a mass accelerator that would, in effect, serve as the first stage of a smallsat launch system, an approach the company argues will allow it to launch payloads at lower costs and higher frequencies than traditional launch vehicles.
