For many years now, astronomers and physicists have been in a conflict. Is the mysterious dark matter that we observe deep in the Universe real, or is what we see the result of subtle deviations from the laws of gravity as we know them?
In 2016, Dutch physicist Erik Verlinde proposed a theory of the second kind: emergent gravity. New research, published in Astronomy and Astrophysics this w Operations underway to restore payload computer on Hubble Telescope

NASA continues to work to resolve a problem with the Hubble Space Telescope payload computer that halted on June 13. After performing tests on several of the computer's memory modules, the results indicate that a different piece of computer hardware may have caused the problem, with the memory errors being only a symptom.
The operations team is investigating whether the Standard Interface EXIM approves $80M to support insurance coverage for Hispasat satellite

NASA has awarded a contract to the University of Michigan for the Cyclone Global Navigation Satellite System (CYGNSS) for mission operations and closeout. A constellation of eight microsatellites, the system can view storms more frequently and in a way traditional satellites are unable to, increasing scientists' ability to understand and predict hurricanes.
The total value of the contract CMRP to play key role in space technology testing network

The University of Wollongong (UOW) will contribute to a national network of facilities to test technology for use in space. Space exploration missions, satellites and permanent space stations require advanced electronic instrumentation with the highest level of reliability. The physically extreme environments in space travel mean most commercially available components are unsuitable.
To en Xi lauds 'new horizon' for humanity in space chat with astronauts

President Xi Jinping on Wednesday lauded the work of three astronauts building China's first space station as opening "new horizons" in humanity's bid to explore the cosmos.
The trio blasted off on a Long March-2F rocket from northwest China's Gobi desert last Thursday, docking around seven hours later at the Tiangong space station, where they will spend the next three months.

WASHINGTON — The European Union is proposing a “launcher alliance” involving companies and governments to develop the next generation of European launch vehicles, although some European startups are skeptical of those plans.
In a June 22 speech highlighting the EU’s space programs, including the signing of a Financial Framework Partnership Agreement with the European Space Agency, the EU commissioner responsible for space highlighted the launcher alliance as part of a “ambitious and disruptive space agenda.

TAMPA, Fla. — Ligado Networks is a step closer toward using its L-band satellite spectrum for terrestrial wireless services in the U.S., after getting clearance from the 3GPP consortium that sets global communications standards for 5G.
The company said June 21 that 3GPP approved technical specifications that enable vendors to build 5G-compatible products on its spectrum.
Patents help build a global map of new space industry
Tuesday, 22 June 2021 15:48 Write a comment
Skoltech researchers and their colleagues from Russia and Serbia have reviewed almost a thousand patents held by some two hundred organizations involved in the New Space economy. The analysis helped draw a comprehensive picture of technology trends in the field. The paper was published in the journal Progress in Aerospace Sciences.
'New Space' is a loosely-defined term that encompasses the recent flurry of space-related activities coming from smaller actors rather than a handful of space-faring nations. Put somewhat simply, while the Apollo missions were more traditional, SpaceX, Rocket Lab (launching small satellites from New Zealand) or LeoLabs (a space junk tracking company) are undeniably parts of a new and different space economy. In a 2020 paper, Skoltech Associate Professor Alessandro Golkar and Alejandro Salado of Virginia Tech found three distinguishing traits of New Space companies: explicit customer focus, new product development approaches, and new business models.
"In a nutshell, the main difference relates to how New Space organizations develop their products and how they approach the business. New Space organizations tend to embrace innovative development processes such as agile, have a risk-taker attitude, and focus on profit.

Space object with orbit stretching into the Oort cloud discovered
Tuesday, 22 June 2021 12:40 Write a comment
Astronomers Pedro Bernardinelli and Gary Bernstein discovered a space object recently that has an orbit around the sun and also stretches into the Oort cloud—they have named it 2014 UN271. The researchers made the discovery while studying archival images collected for the Dark Energy Survey over the years 2014 to 2018. Since its discovery, entities such as the MMPL forum, the Minor Planet Center and JPL Solar System Dynamics have been tracking the object and have found that it will make its closest approach to Earth in 2031.
Measurements of the object put it between the size of a very small planet and a comet—it is believed to have a diameter of 100 to 370 km. If it turns out to be on the larger end of that spectrum, it would mark the largest Oort cloud object discovered to date. But it is the path of the object that has drawn the attention of astronomers—its orbit is nearly perpendicular to the plane created by the nine inner planets and takes it deep into the solar system and into the Oort cloud.
