NASA sounding rocket to help fix Sun observatory

Washington: NASA is all set to launch a sounding rocket to help adjust a key instrument aboard NASA’s Solar Dynamics Observatory (SDO).

The SDO is studying the solar atmosphere to help scientists understand the Sun’s influence on Earth and near-Earth space.

The seventh calibration mission for an instrument on NASA’s SDO will launch into space onboard a sounding rocket for a 15-minute flight.

The instrument to be calibrated is called EUV Variability Experiment (EVE) where EUV stands for extreme ultraviolet.

EVE’s job is to observe the total energy output of the Sun in EUV light waves.

The calibration mission is scheduled for launch on Thursday on a Terrier-Black Brant suborbital sounding rocket from White Sands Missile Range, New Mexico.

Solar instruments in space naturally degrade over time, bombarded by a constant stream of solar particles that can cause a film of material to adhere to the optics.

Decades of research and engineering skill have improved protecting such optics, but one crucial solution is to regularly recalibrate the instruments to accommodate such changes.

“Parts of the optical coating can darken due to exposure to solar ultraviolet radiation and high energy particles in space, so the sensitivity of the EVE detector decreases over time,” said Tom Woods, principal investigator for this calibration mission from University of Colorado in Boulder.

“By determining how much the instrument has degraded since last time, we can adjust data processing algorithms to account for that change,” he said.

EVE measures the total energy output of the Sun known as irradiance for each wavelength of light in the extreme ultraviolet range.

By tracking the irradiance, scientists can observe how it changes with different events on the sun.

None of these wavelengths can penetrate the Earth’s atmosphere to reach humans on the Earth, but each can have a profound effect on the air above our planet, the US space agency said in a statement.

Casino Days Reveal Internal Data on Most Popular Smartphones

International online casino Casino Days has published a report sharing their internal data on what types and brands of devices are used to play on the platform by users from the South Asian region.

Such aggregate data analyses allow the operator to optimise their website for the brands and models of devices people are actually using.

The insights gained through the research also help Casino Days tailor their services based on the better understanding of their clients and their needs.

Desktops and Tablets Lose the Battle vs Mobile

The primary data samples analysed by Casino Days reveal that mobile connections dominate the market in South Asia and are responsible for a whopping 96.6% of gaming sessions, while computers and tablets have negligible shares of 2.9% and 0.5% respectively.

The authors of the study point out that historically, playing online casino was exclusively done on computers, and attribute thе major shift to mobile that has unfolded over time to the wide spread of cheaper smartphones and mobile data plans in South Asia.

“Some of the reasons behind this massive difference in device type are affordability, technical advantages, as well as cheaper and more obtainable internet plans for mobiles than those for computers,” the researchers comment.

Xiaomi and Vivo Outperform Samsung, Apple Way Down in Rankings

Chinese brands Xiaomi and Vivo were used by 21.9% and 20.79% of Casino Days players from South Asia respectively, and together with the positioned in third place with a 18.1% share South Korean brand Samsung dominate the market among real money gamers in the region.

Cupertino, California-based Apple is way down in seventh with a user share of just 2.29%, overshadowed by Chinese brands Realme (11.43%), OPPO (11.23%), and OnePlus (4.07%).

Huawei is at the very bottom of the chart with a tiny share just below the single percent mark, trailing behind mobile devices by Motorola, Google, and Infinix.

The data on actual phone usage provided by Casino Days, even though limited to the gaming parts of the population of South Asia, paints a different picture from global statistics on smartphone shipments by vendors.

Apple and Samsung have been sharing the worldwide lead for over a decade, while current regional leader Xiaomi secured their third position globally just a couple of years ago.

Striking Android Dominance among South Asian Real Money Gaming Communities

The shifted market share patterns of the world’s top smartphone brands in South Asia observed by the Casino Days research paper reveal a striking dominance of Android devices at the expense of iOS-powered phones.

On the global level, Android enjoys a comfortable lead with a sizable 68.79% share which grows to nearly 79% when we look at the whole continent of Asia. The data on South Asian real money gaming communities suggests that Android’s dominance grows even higher and is north of the 90% mark.

Among the major factors behind these figures, the authors of the study point to the relative affordability of and greater availability of Android devices in the region, especially when manufactured locally in countries like India and Vietnam.

“And, with influencers and tech reviews putting emphasis on Android devices, the choice of mobile phone brand and OS becomes easy; Android has a much wider range of products and caters to the Asian online casino market in ways that Apple can’t due to technical limitations,” the researchers add.

The far better integration achieved by Google Pay compared to its counterpart Apple Pay has also played a crucial role in shaping the existing smartphone market trends.
