Phase Four achieves electric thruster operation on Air Force Green Propellant ASCENT
Tuesday, 08 November 2022 05:07
Phase Four, the creator of the radio-frequency thruster (RF thruster) for satellite propulsion, has successfully demonstrated operation of its RF thruster using the Air Force Research Laboratory's green propellant, ASCENT (formerly AF-M315E). The achievement, made under a U.S. Space Force contract awarded at the 2021 Space Force Pitch Day, enables multi-mode propulsion capability, which combines First geostationary navigation receiver from Beyond Gravity will be sent to orbit
Tuesday, 08 November 2022 05:07
Beyond Gravity (formerly RUAG Space) delivered a geostationary navigation receiver, called GEORIX, and an antenna to Maxar in 2021. The receiver precisely determines a satellite's position in orbit. Maxar installed GEORIX on Intelsat-40e, a geostationary communications satellite.
Intelsat-40e is hosting NASA's climate payload called Tropospheric Emissions Monitoring of Pollution (TEMPO). G One Cygnus solar array deployed so far

Tuesday, 08 November 2022 05:07
NASA and its mission partners are gearing up for a busy 2023 with crew launches and returns from the International Space Station. NASA worked closely with its international partners and commercial crew providers, Boeing and SpaceX, to secure new target launch dates for the upcoming flights that are optimal for space station needs.

NASA and Boeing n Earth's oldest stromatolites and the search for life on Mars
Tuesday, 08 November 2022 05:07
The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to advanced alteration and metamorphism.

A new model that accounts for the interplay of forces acting on newborn planets can explain two puzzling observations that have cropped up repeatedly among the more than 3,800 planetary systems cataloged to date.
One puzzle known as the "radius valley" refers to the rarity of exoplanets with a radius about 1.8 times that of Earth. NASA's Kepler spacecraft observed planets of this size abou Intelsat chooses SWISSto12 to build Intelsat 45

Experiments to study gravity's impact on bone cells are heading to the International Space Station
Monday, 07 November 2022 20:38
A pair of experiments exploring bone density, designed by engineers at the University of Michigan, has left the Wallops Island, Virginia launchpad aboard a Northrop Grumman Corp. Antares rocket for the International Space Station (ISS).
Allen Liu, U-M associate professor of mechanical engineering, and members of his research team detail how experiments in space can shed light on osteoporosis, a condition affecting hundreds of millions of people around the world—as well as how to keep astronauts safer.
What's the connection between bone density, osteoporosis and gravity that makes this space-based research relevant to regular people?

Zimbabwe launches first nano-satellite
Monday, 07 November 2022 18:45Zimbabwe on Monday announced the launch of its first nano-satellite into space in a bid to help collect data to monitor disasters, boost agriculture and enhance mineral mapping.
A rocket carrying the tiny satellite, dubbed ZIMSAT-1, successfully launched from Virginia in the United States alongside Uganda's first satellite as part of the Japan Aerospace Exploration Agency (JAXA) multi-nation project.
"History unfolding.#ZimSat1 now space bound!" government spokesman Nick Mangwana wrote in a tweet. "This is a scientific milestone for the country."
The US National Aeronautics and Space Administration (NASA) tweeted Monday the rocket "will carry experiments about plant mutations and mudflow structure, as well as satellites from Japan, Uganda & Zimbabwe".
Zimbabwe's plans to launch the satellite started in 2018, less than a year after President Emmerson Mnangagwa came into office following the removal of veteran ruler Robert Mugabe through a military coup.
He created the Zimbabwean National Geospatial and Space Agency (ZINGSA) to promote research and innovation in the embattled southern African nation.
The launch of the satellite—barely the size of a shoebox—sparked much debate on social media with some hailing the government for the achievement while others mocked the effort.
"Launching a satellite when the economy is fragile is stupidity.
