Study Looks More Closely at Mars' Underground Water Signals
Write a comment
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 Research looks to outer space to learn about human health on Earth

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.

The duo performed the second extra vehicular activity to bolt in place and unfurl an IROSA, or ISS Roll-Out Solar Array, on Sunday 20 June.
The series of spacewalks last week was not without some challenges. During the first spacewalk on 16 June, Shane experienced a small technical problem in his spacesuit that required him to return to the airlock and restart his Display and Control Module. This module provides astronauts with continuous information on pressure, temperature and other vital data during a spacewalk.
Though the restart was successful and Shane was in no danger, it delayed the duo's work, preventing them from completing installation of the first new solar array as planned.
The duo succeeded in taking the IROSA panel out of its storage area outside the Space Station and passed from spacewalker to spacewalker to the worksite. There the rolled arrays were secured. The spacewalk lasted 7 hours and 15 minutes.
During the second spacewalk, the duo unfolded, bolted and connected the wires.

The Federal Aviation Administration (FAA) and the Department of the Air Force signed an agreement June 15 aimed at eliminating red tape while protecting public safety during commercial space activities at ranges operated by the U.S. Space Force.
The agreement recognizes common safety standards for FAA-licensed launch and reentry activities that occur on, originate from, or return to Cape C NASA balloon detects California earthquake, next stop, Venus?

The technique is being developed to detect venusquakes. A new study details how, in 2019, it made the first balloon-borne detection of a quake much closer to home.
Between July 4 and July 6, 2019, a sequence of powerful earthquakes rumbled near Ridgecrest, California, triggering more than 10,000 aftershocks over a six-week period. Seeing an opportunity, researchers from NASA's Jet Propulsi Using visible light to decompose CO2 with high efficiency

Carbon dioxide (CO2) emissions from human activities have risen drastically over the last century and a half and are seen as the primary cause of global warming and abnormal weather patterns. So, there has been considerable research focus, in a number of fields, on lowering our CO2 emissions and its atmospheric levels.
One promising strategy is to chemically break down, or 'reduce,' CO2 us European system speeds data flow with 50 000 links

Following recent successful experimentation with Marines at Camp Lejeune, North Carolina, DARPA's Prototype Resilient Operations Testbed for Expeditionary Urban Scenarios (PROTEUS) will transition to the Marine Corps Warfighting Laboratory (MCWL) in Quantico, Virginia.

Modern weather forecasts rely heavily on data retrieved from numerical weather prediction models. These models continue to improve and have advanced considerably throughout more than half a century. However, forecast reliability depends on the quality and accuracy of initialization data, or a sample of the current global atmosphere when the model run is started.
