Icy clouds could have kept early Mars warm enough for rivers and lakes, study finds
One of the great mysteries of modern space science is neatly summed up by the view from NASA's Perseverance, which just landed on Mars: Today it's a desert planet, and yet the rover is sitting right next to an ancient river delta.
The apparent contradiction has puzzled scientists for decades, especially because at the same time that Mars had flowing rivers, it was getting less than a third Star light, star bright as explained by math
Not all stars shine brightly all the time. Some have a brightness that changes rhythmically due to cyclical phenomena like passing planets or the tug of other stars. Others show a slow change in this periodicity over time that can be difficult to discern or capture mathematically. KAUST's Soumya Das and Marc Genton have now developed a method to bring this evolving periodicity within the framewo Blue Origin protests NASA Human Landing System award
WASHINGTON — Blue Origin filed a protest with the Government Accountability Office April 26 over NASA’s decision to select only SpaceX for its Human Landing System (HLS) program, arguing the agency “moved the goalposts” of the competition.
Startup and established IoT satellite operators exchange blows in regulatory battle
TAMPA, Fla. — U.S.-based startup Swarm Technologies and 28-year old Orbcomm, both pursuing the fast-growing market for connecting Internet of Things (IoT) sensors to satellites, are locked in a regulatory tussle over plans to expand overseas.
Orbcomm is challenging a letter the Federal Communications Commission (FCC) sent March 10, which aimed to clarify how it and Swarm would share spectrum in Very High Frequency (VHF) bands worldwide.
Delta 4 Heavy sends spy satellite to orbit in ULA’s first launch of 2021
WASHINGTON — United Launch Alliance launched a classified National Reconnaissance Office spy satellite on a Delta 4 Heavy rocket April 26 at 1:47 p.m. Pacific from Space Launch Complex-6 at Vandenberg Air Force Base, California.
Probing deep space with Interstellar
When the four-decades-old Voyager 1 and Voyager 2 spacecraft entered interstellar space in 2012 and 2018, respectively, scientists celebrated. These plucky spacecraft had already traveled 120 times the distance from the Earth to the sun to reach the boundary of the heliosphere, the bubble encompassing our solar system that's affected by the solar wind. The Voyagers discovered the edge of the bubble but left scientists with many questions about how our Sun interacts with the local interstellar medium. The twin Voyagers' instruments provide limited data, leaving critical gaps in our understanding of this region.
Northrop Grumman designs protected Tactical SATCOM Payload Prototype for the Space Force
Northrop Grumman Corporation has been selected by the U.S. Space Force's (USSF) Space and Missile Systems Center (SMC) to proceed with its ongoing Protected Tactical SATCOM (PTS) Rapid Prototype program, with a flight demonstration of the company's PTS payload set to occur in 2024.
Selected for the initial award through the Space Enterprise Consortium, this continuation enables Northrop Gr North Korea's satellites in orbit not transmitting data
North Korean satellites launched into orbit are either unstable or not fully operational, and a reconnaissance satellite launched in February 2016 is not relaying data, a South Korean analyst said.
Song Geun-ho, a professor at Korea Defense Language Institute at South Korea's Joint Forces Military University, said in a new report on North Korea's space program that Pyongyang's claims of vi AFRL Inspire to feature special guest speaker from Space Operations Command

AFRL Inspire, a two-hour special event with eight TEDx-style talks, will be livestreamed from the Air Force Institute of Technology's Kenney Hall Auditorium April 28 beginning at 2 p.m. EDT. Inspire showcases the innovative ideas and passionate people AFRL has to offer as they provide entertaining and thought-provoking talks, share personal stories and On a changing planet, NASA goes Green
NASA is responsible for collecting much of the data that people use to explain humanity's environmental impact on Earth, from documenting climate change and its impacts on ice, sea level and weather patterns, to monitoring the health of forests and the movement of freshwater.
But NASA doesn't just report the data. It also acts on it.
NASA facilities across the United States are each
