Ingenuity on Sol 39

Posted on Posted in NASA, TweetTagged , , , Leave a comment

The Mars Ingenuity Helicopter, all four landing legs down, was captured here on sol 39 (March 30) slung beneath the belly of the Perseverance rover. The near ground level view is a mosaic of images from the WATSON camera on the rover’s SHERLOC robotic arm. Near the center of the frame the experimental helicopter is suspended just a few centimeters above the martian surface. Tracks from Perseverance extend beyond the rover’s wheels with the rim of Jezero crater visible about 2 kilometers in the distance. Ingenuity has a weight of 1.8 kilograms or 4 pounds on Earth. That corresponds to a weight of 0.68 kilograms or 1.5 pounds on Mars. With rotor blades spanning 1.2 meters it will attempt to make the first powered flight of an aircraft on another planet in the thin martian atmosphere, 1 percent as dense as Earth’s, no earlier than sol 48 (April 8). via NASA https://ift.tt/2Py4BgL

Wikipedia article of the day is Scarlet myzomela. Check it out: https://ift.tt/2OnnsdW Summary: The scarlet myzomela (Myzomela sanguinolenta) is a small bird of the honeyeater family Meliphagidae native to Australia. It was described by English ornithologist John Latham in 1801. At 9 to 11 centimetres (3.5 to 4.3ย in) long, it is the smallest honeyeater in Australia. It has a short tail and relatively long down-curved bill. The male (example pictured) is a striking bright red with black wings, while the female is entirely brown. It is more vocal than most honeyeaters; its varied calls include a bell-like tinkling. Found along most of the eastern coastline, the scarlet myzomela is migratory in the southern parts of its range. Its natural habitat is forest, where it forages mainly in the upper tree canopy for insects as well as nectar. Up to three broods may be raised over the course of a breeding season. The female lays two or rarely three flecked white eggs in a cup-shaped nest 5 centimetres (2ย in) across, high in a tree. The species is not threatened.
