Study Looks More Closely at Mars' Underground Water Signals
Friday, 25 June 2021 05:24
A new paper finds more radar signals suggesting the presence of subsurface 'lakes,' but many are in areas too cold for water to remain liquid.
In 2018, scientists working with data from ESA's (the European Space Agency's) Mars Express orbiter announced a surprising discovery: Signals from a radar instrument reflected off the Red Planet's south pole appeared to reveal a liquid subsurface la Collection of starshade research helps advance exoplanet imaging by space telescopes
Friday, 25 June 2021 05:24
The open access Journal of Astronomical Telescopes, Instruments, and Systems (JATIS) has published a special section on the latest science, engineering, research, and programmatic advances of starshades, the starlight-suppression technology integral to extra-solar and exoplanet detection.
Section topics range from starshade programs and missions, to various aspects of related technologies, AiRANACULU wins second NASA contract for advanced space communications system
Friday, 25 June 2021 05:24
AiRANACULUS, a private, Massachusetts-based technology company providing early stage research, development, prototyping and consulting services, announced it has been awarded a second NASA Small Business Innovation Research contract for development of an advanced space communications system to support upcoming missions to the Moon and Mars.
Under the new contract, AiRANACULUS will develop NASA to send mannequins to moon to prepare for crewed missions

NASA's upcoming Artemis I mission to the moon, planned for later this year, won't have a human crew, but the space agency is preparing three inanimate occupants of the Orion capsule to measure radiation and vibrations.
The Artemis I "crew" members, mannikins, will help NASA test radiation, vibration and impacts from landing before the space agency plans to send astronauts in an Orion ca Technical snags make US Astronauts' lunar landing in 2024 'less likely', GAO Says
Friday, 25 June 2021 05:24
NASA's 2024 deadline to return humans to the Moon looks increasingly unlikely due to reliance on technology that has yet to be fully developed, the General Accountability Office (GAO) said in a report on Thursday.
"A fast-tracked schedule to meet this ambitious date - along with some technical risks - mean that it's less likely a lunar landing will happen in 2024," a GAO press release expl Cosmic dawn occurred 250 to 350 million years after Big Bang
Friday, 25 June 2021 05:24
Cosmic dawn, when stars formed for the first time, occurred 250 million to 350 million years after the beginning of the universe, according to a new study led by researchers at University College London (UCL) and the University of Cambridge.
The study, published in the Monthly Notices of the Royal Astronomical Society, suggests that the NASA James Webb Space Telescope (JWST), scheduled to British-built satellites will help fight climate change and save wildlife
Friday, 25 June 2021 05:24
Monitoring and tackling climate change and tracking endangered wildlife are among the exciting features of three UK-built satellites set to launch on a SpaceX rocket on Friday 25th June.
UK companies have received nearly 15 million pounds from the UK Space Agency, through the European Space Agency's Pioneer Partnership Programme, to develop the trio of satellites due to lift off from NASA' Solar System samples touch down in Leicester
Friday, 25 June 2021 05:24
Samples from other worlds will be examined by space scientists at the University of Leicester as they continue to study the building blocks of the Solar System.
Some of the first particles from asteroid Ryugu - returned by Japan Aerospace Exploration Agency (JAXA) probe Hayabusa2 in 2020 - and samples from the Winchcombe meteorite, which fell to Earth earlier this year, will be scrutinised The fifth quartet: Excited neon discovery could reveal star qualities
Friday, 25 June 2021 05:24
Scientists from the Department of Physics and the Research Center for Nuclear Physics (RCNP) at Osaka University, in collaboration with Kyoto University, used alpha particle inelastic scattering to show that the theorized "5a condensed state" does exist in neon-20. This work may help us obtain a better understanding the low-density nucleon many-body systems.
All elements besides hydrogen a NASA studying larger Mars helicopters
Thursday, 24 June 2021 21:44
WASHINGTON — With the Ingenuity helicopter continuing to demonstrate its abilities on Mars, NASA engineers are examining concepts for larger, more capable rotorcraft that could be flown on future missions.
Ingenuity performed its eighth flight on Mars June 21, traveling 160 meters and landing at a new site 133.5 meters from the Perseverance rover.
U.S. Army selects Iridium to develop payload for low Earth orbit satellite navigation system

Research looks to outer space to learn about human health on Earth
Thursday, 24 June 2021 15:49
As an oncologist, Adam Dicker has seen how cancer treatments can pummel the body to knock out tumors, sometimes leading to deteriorating bones, more infections, and haywire sleep cycles. But others have observed similar ailments in a group of healthy people: astronauts who spend time in space.
Next year, Dicker and fellow researchers at Sidney Kimmel Medical College at Thomas Jefferson University in Philadelphia will launch three studies of how space travel affects aspects of the human body—immunity, microbes in urine, and stress—as part of the first private mission to the International Space Station. Researchers believe that the unique environment in space can also shed light on human health on Earth.
"I never thought I'd ever do a project in space," said Paul H. Chung, assistant professor of urology at Sidney Kimmel Medical College,who is involved in one of the space studies. "Most people don't even know the logistics of how someone would do a project in space."
The eight-day mission is the first of its kind to be approved by NASA. Organized by Axiom Space, on Jan. 22, 2022 a SpaceX rocket will ferry four paying passengers to the International Space Station along with 44 scientific experiments commissioned by the Ramon Foundation and the Israel Space Agency.
