An international team of astronomers has overturned a longstanding belief that stars and dark matter interact in a mysterious way to create uniform density structures across different galaxies. This finding, published in 'Monthly Notices of the Royal Astronomical Society (MNRAS)', challenges a theory that had perplexed scientists for 25 years.

HawkEye 360 Inc., a leader in space-based radio frequency (RF) data analytics, has successfully launched its Cluster 10 satellites into orbit, expanding its constellation to 31 satellites. The deployment was achieved through the collaboration with Space Flight Laboratory (SFL) and was part of SpaceX's Transporter-11 Rideshare mission, coordinated by launch integrator Exolaunch.

The Copernicus Sentinel-2C satellite is now fully fueled and pressurized, ready for its upcoming launch on 4 September from Europe's Spaceport in French Guiana. The satellite has been loaded with 133 kg of hydrazine, and its tanks have been pressurized with helium to 21 bars.
Sentinel-2C arrived at the Spaceport on 22 July, where it has undergone final preparations for its journey aboard a SpaceX rolls out new booster for Cape Canaveral launch

SpaceX launches lately have been pushing the record envelope for booster reflight, but a Starlink launch Tuesday morning rolled out a brand new first stage.
A Falcon 9 rocket carrying 22 of the company's internet satellites lifted off at 9:20 a.m. from Cape Canaveral Space Force Station's Space Launch Complex 40.
Shiny and white, the booster was missing the telltale signs of having been flown before, as boosters are normally covered with black carbon scoring. This was the first launch of the booster, which is targeted to be used to support the Crew-9 human spaceflight next month for launch No. 2.
It made a recovery landing downrange in the Atlantic on the droneship A Shortfall of Gravitas.
The company has four boosters that have completed at least 20 launches and landings, and is in the midst of a certification process to get them up to 40 each.
This was the 59th launch from the Space Coast from all providers in 2024. SpaceX has been responsible for all but four, with 39 coming from SpaceX from Canaveral and the other 16 from SpaceX from neighboring KSC.
NASA CubeSats launch as commercial rideshares

A pair of CubeSats from NASA's Pathfinder Technology Demonstrator, or PTD, series lifted off on SpaceX's Transporter-11 rideshare mission at 11:56 a.m. PDT Friday, August 16, from Vandenburg Space Force Base in California.
The two small satellites, PTD-4 and PTD-R, will help advance NASA's efforts to validate novel technologies and increase small spacecraft capabilities in order to shape the future of space exploration and technology.
PTD-4 will demonstrate a high-power, low-volume deployable solar array with an integrated antenna, while PTD-R will focus on testing simultaneous ultraviolet and short-wave infrared optical sensing from space for the first time via two 85-mm aperture monolithic telescopes mounted side-by-side.

A European lander could return an ice core for a fraction of the cost of Europa Clipper
Tuesday, 20 August 2024 13:50 Write a comment
Cost is a major driving factor in the development of space exploration missions. Any new technology or trick that could lower the cost of a mission makes it much more appealing for mission planners. Therefore, much of NASA's research goes into those technologies that enable cheaper missions.
For example, a few years ago, NASA's Institute for Advanced Concepts (NIAC) supported a project by Michael VanWoerkom of ExoTerra Resource to develop a lander mission that could support a sample return from Europa. Let's examine what made that mission different from other Europa mission architectures.
The Nano Icy Moons Propellant Harvester (NIMPH) mission relies on three main advancements for one significant result: a 10x reduction in the overall mission cost. That reduced cost comes mainly from a single fact—the mission's weight has dropped below the threshold where it can be launched by an Atlas V rather than the SLS, as similar missions would require.

Four members of a SpaceX mission that will carry out the first ever private spacewalk arrived in Florida on Monday ahead of their takeoff next week.
The five-day expedition, named Polaris Dawn, will be led by US billionaire Jared Isaacman, who already chartered the first all-civilian orbital spaceflight in 2021, called Inspiration4.
"It's been two and a half years since we announced the Polaris program. It's been a really exciting journey of development and training," Isaacman told a press conference Monday.
He did not reveal how much he has spent on the program, which includes a total of three missions and which he jointly funds with SpaceX.
For the trip, the company has developed its first generation of space suits, which are white and futuristic.
