Underwater snow gives clues about Europa's icy shell
Thursday, 18 August 2022 03:40
Below Europa's thick icy crust is a massive, global ocean where the snow floats upwards onto inverted ice peaks and submerged ravines. The bizarre underwater snow is known to occur below ice shelves on Earth, but a new study shows that the same is likely true for Jupiter's moon, where it may play a role in building its ice shell.

NASA's new moon rocket arrived at the launch pad Wednesday ahead of its debut flight in less than two weeks.
The 322-foot (98-meter) rocket emerged from its mammoth hangar late Tuesday night, drawing crowds of Kennedy Space Center workers, many of whom were not yet born when NASA sent astronauts to the moon a half-century ago.
Facilitating the development of LEO mega constellations
Wednesday, 17 August 2022 16:36
The rapid development of Low Earth Orbit (LEO) mega constellations has significantly contributed to several aspects of human scientific progress, such as communication, navigation, and remote sensing. However, unrestrained deployment of constellations has also strained orbital resources and increased spacecraft congestion in LEO, which seriously affects the safety of in-orbit operations of many space assets.
For the long-term and sustainable development of space activities in LEO regions, space environment stability must be maintained using more rational surveillance and governance mechanisms. In a review paper recently published in Space: Science & Technology, Jingrui Zhang from School of Aerospace Engineering, Beijing Institute of Technology, analyzed the research gap and facilitated the development of LEO mega constellations.
First of all, the author reviewed the current developments of typical LEO mega constellations, including Starlink, OneWeb, Iridium Next, Globalstar, and Flock. Taking SpaceX's Starlink as an example, it aims to build a LEO constellation containing 42,000 satellites to achieve global coverage, high-speed, large-capacity, and low-latency space-based global communication system. Starlink has shown excellent performance in related fields, such as international aviation and ocean transportation. Moreover, Starlink can be constructed as a powerful command and communication network and has already been an important symbol of the weaponization of outer space in the United States.
Test chamber for NASA's new cosmic mapmaker makes dramatic entrance
Wednesday, 17 August 2022 15:32
After three years of design and construction, a monthlong boat ride across the Pacific Ocean, and a lift from a 30-ton crane, the customized test chamber for NASA's upcoming SPHEREx mission has finally reached its destination at Caltech's Cahill Center for Astronomy and Astrophysics in Pasadena.
Set to launch no earlier than June 2024, SPHEREx (short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) will make a unique map of the cosmos that will contain hundreds of millions of objects, including stars, galaxies, star-forming regions, and other cosmic wonders.

Access to medical supplies is a major concern for astronauts. Sleep issues, pain, congestion and allergies are all common complaints from those on extra-terrestrial missions.
The use of medication by American crewmembers on the International Space Station (ISS) was monitored between 2002 and 2012. And according to the data, astronauts used sleep tablets 10 times more often than earthlings. They also used ibuprofen for pain stemming from space flight pressure changes, higher carbon dioxide levels and joint issues.
Unfortunately, the longer the space flight, the higher the chances of experiencing acute illness. Common health problems for astronauts include a weakened immune system, bone decalcification and low blood pressure.
On Earth, most medicines expire within a year.

To prepare Europe for future decision making on Space-Based Solar Power, ESA has proposed a preparatory programme for Europe, initially named SOLARIS, for the upcoming ESA Council at Ministerial Level in November 2022.
Space-based solar power is a potential source of clean, affordable, continuous, abundant and secure energy. This basic concept has been given fresh urgency by the need for new sources of clean and secure energy to aid Europe’s transition to a Net Zero carbon world by 2050. If Europe wants to benefit from this game-changing capability then we need to start investing now.
ESA has undertaken
