Starlink Posts Stunning 600 Mbps+ Download Speed & Shocks In Multiple Tests

SpaceX’s Starlink satellite internet constellation continues to deliver stunning download speeds in Germany. The network, comprised of thousands of satellites, became well known all over for its remarkable download speeds soon after it was opened for public participation. However, the hype around Starlink, the world’s first commercially successful low Earth orbit (LEO) satellite internet, led to millions of users signing up for SpaceX’s service — faster than SpaceX could add capacity. This led to performance downgrades across areas of high demand, particularly in several regions of America. However, now and then, Starlink reminds everyone of its true potential, and that’s the case with today’s internet tests.
Starlink Crosses 500 Mbps In Multiple Download Speed Tests
Today’s test comes courtesy of a Reddit user who recently received their Starlink user terminal after moving to rural Germany. Starlink tests in the European country have often produced remarkable results, owning partly due to lesser congestion as well as the placement of satellites. SpaceX is gradually building out its constellation, which eventually aims to be made of thousands of satellites. This leads to unevenly spread out satellites that benefit some areas in the form of higher speeds.
The greatest hazard for humans on deep-space exploration missions is radiation. To protect astronauts venturing out beyond Earth’s protective magnetosphere and sustain a permanent presence on Moon and/or Mars, advanced passive radiation protection is highly sought after. Due to the complex nature of space radiation, there is likely no one-size-fits-all solution to this problem, which is further aggravated by up-mass restrictions. In search of innovative radiation-shields, biotechnology holds unique advantages such as suitability for in-situ resource utilization (ISRU), self-regeneration, and adaptability. Certain fungi thrive in high-radiation environments on Earth, such as the contamination radius of the Chernobyl Nuclear Power Plant. Analogous to photosynthesis, these organisms appear to perform radiosynthesis, using pigments known as melanin to convert gamma-radiation into chemical energy. It is hypothesized that these organisms can be employed as a radiation shield to protect other lifeforms. Here, growth of Cladosporium sphaerospermum and its capability to attenuate ionizing radiation, was studied aboard the International Space Station (ISS) over a time of 30 days, as an analog to habitation on the surface of Mars. At full maturity, radiation beneath a ≈ 1.7 mm thick lawn of the melanized radiotrophic fungus (180° protection radius) was 2.17±0.35% lower as compared to the negative control. Estimations based on linear attenuation coefficients indicated that a ~ 21 cm thick layer of this fungus could largely negate the annual dose-equivalent of the radiation environment on the surface of Mars, whereas only ~ 9 cm would be required with an equimolar mixture of melanin and Martian regolith. Compatible with ISRU, such composites are promising as a means to increase radiation shielding while reducing overall up-mass, as is compulsory for future Mars-missions.
