DOUGHNUT (donut?) and whale FOUND ON PLUTO

E-minus 7 days until NASA's space lab gets intimate with strange dwarf


Pics NASA has published new photos of the freezeworld Pluto, taken by its Far-travelling New Horizons probe - that prominently feature what appears to be a pareidolic whale and a tasty doughnut (or donut).

The New Horizon space podule is closing in for its 14 July flyby of the frosty dwarf planet.

The images, taken between 27 June and 3 July, were snapped by the Long Range Reconnaissance Imager (LORRI) on New Horizons. LORRI's pics were subsequently combined with lower-resolution color data from the spacecraft's Ralph instrument to form a Google Earth KMZ.

LORRI is a high resolution imaging instrument for visible wavelengths, which has been complimented by the Ralph telescope, a panchromatic and colour imaging instrument and infra-red spectrometer.

Ralph has a wife, Alice, an ultraviolet imaging spectrometer, although she wasn't involved in the production of this map.

The map these instruments produced offers the mission boffins a valuable tool in analysing "the complex and intriguing pattern" of bright and dark markings on Pluto's surface.

The boffins note that "features from all sides of Pluto can now be seen at a glance and from a consistent perspective, making it much easier to compare their shapes and sizes".

The center of the map corresponds to the side of Pluto that will be seen close-up during the Bastille Day flyby.

Apparently, the "whale" is the elongated dark area along the equator on the left side of the map. It is one of the darkest regions visible to New Horizons and measures some 1,860 miles (3,000 kilometers) in length, or the length of 120,000 of our largest terrestrial cetaceans.

To the right of the whale's "head" is the brightest region visible on the planet, which is roughly 990 miles (1,600 kilometers [64,000 whales]) across.

The astroboffins reckon this may be a region where relatively fresh deposits of frost – perhaps made from methane, nitrogen, carbon monoxide, or some mixture thereof – have formed a bright coating.

Continuing to the right, along the equator, there are four mysterious dark spots which intrigued the world, each of which is hundreds of miles across.

Meanwhile, the whale's "tail", which NASA notes is at the left end of the dark feature, that is, on the side other from the head, cradles a bright doughnut-shaped feature about 200 miles (350 kilometers [14,000 whales]) across.

At first glance it resembles circular features seen elsewhere in the solar system, from impact craters to volcanoes, but the boffins are restraining themselves from offering any interpretations of this and other features on Pluto until more detailed images are at hand.

The higher-resolution images, which will be provided in the days to come, will allow mission scientists to make more accurate maps, but this release should provide exciting foreplay for extraplanetary voyeurs.

"We're at the 'man in the moon' stage of viewing Pluto," offered John Spencer of the Southwest Research Institute, Boulder, Colorado, who is deputy leader of the Geology, Geophysics and Imaging team. "It’s easy to imagine you're seeing familiar shapes in this bizarre collection of light and dark features. However, it's too early to know what these features really are."

    Previous injunction that ordered company to allow non-Apple payments systems is suspended

    Apple will not be required to implement third-party in-app payments systems for its App Store by 9 December, after a federal appeals court temporarily suspended the initial ruling on Wednesday.

    As part of its ongoing legal spat with Epic, a judge from the Northern District Court of California said Apple wasn’t a monopoly, but agreed it’s ability to swipe up to a 30 per cent fee in sales processed in iOS apps was uncompetitive. Judge Yvonne Gonzalez Rogers ordered an injunction, giving the iGiant 90 days to let developers add links or buttons in their apps to direct users to third-party purchasing systems.

    Those 90 days were set to end on 9 December. If developers were allowed to process financial transactions using external systems they wouldn’t have to hand over their profits to Apple, they argued. When Apple tried to file for a motion to stay, which would pause the injunction until it filed an appeal, Rogers denied its request.

    Donated $110K to Democrats in recent years

    United States president Joe Biden has announced his intention to nominate former HPE and eBay CEO Meg Whitman as Ambassador Extraordinary and Plenipotentiary to the Republic of Kenya.

    The Biden administration's announcement of the planned nomination reminds us that Whitman has served as CEO of eBay, Hewlett Packard Enterprise, and Quibi. Whitman also serves on the boards of Procter & Gamble, and General Motors.

    The announcement doesn't remind readers that Whitman has form as a Republican politician – she ran for governor of California in 2010, then backed the GOP's Mitt Romney in his 2008 and 2012 bids for the presidency. She later switched political allegiance and backed the presidential campaigns of both Hillary Clinton and Joe Biden.
