The Shuttle Radar Topography Mission mast was deployed properly to its entire duration, along with the antenna was turned to its operation place. Right after A prosperous checkout from the radar units, mapping commenced at twelve:31 a.
Hi, I’m Doug Rowland. And that i’m a scientist researching the Earth’s higher ambiance. Which’s an interesting region, as it’s in which the Earth’s atmosphere that we breathe, turns into a gasoline called plasma that’s electrically charged.
This star chart for M99 represents the see from mid-northern latitudes for that specified month and time.
To be a source of light and warmth for all times on the planet, researchers wish to know how our Sunlight operates, why it adjustments, And exactly how these changes impact lifetime on the planet. The Sunshine’s constant stream of photo voltaic material and radiation can influence spacecraft, communications techniques, and orbiting astronauts.
The protoplanetary nebula period is a late stage while in the lifetime of a star through which it's ejected a shell of hydrogen fuel which is promptly heating up. This phase only lasts to get a several thousand many years prior to the protoplanetary nebula’s central star reaches around thirty,000 Kelvin. At this point, the central star is generating more than enough Vitality to produce its bordering shell of gasoline glow, starting to be what’s known as a planetary nebula.
Endeavour carried a pupil experiment called EarthKAM, which took two,715 photographic photos of Earth via an overhead flight deck window. The NASA-sponsored experiment authorized junior high school pupils to select photo targets and view the photographs via the online market place.

This picture, taken from the NASA/ESA Hubble Room Telescope, exhibits an in depth see from the spiral arms on one aspect in the galaxy Messier ninety nine. Messier ninety nine is actually a so-identified as grand design spiral, with extensive, substantial and Plainly defined spiral arms — giving it a structure fairly much like the Milky Way. Lying all around fifty million gentle-decades away, Messier ninety nine is one of above a thousand galaxies which make up the Virgo Cluster, the closest cluster of galaxies to us. Messier 99 alone is relatively dazzling and large, indicating it absolutely was one of many to start with galaxies to generally be discovered, way back again inside the 18th century. This acquired it a spot in Charles Messier’s well-known catalogue of astronomical objects. Lately, many unexplained phenomena in Messier ninety nine have already been studied by astronomers. Among these is the character of one of the brighter stars noticeable During this impression. Catalogued as PTF 10fqs, and visual for a yellow-orange star in the very best-still left corner of this image, it was very first noticed via the Palomar Transient Facility, which scans the skies for unexpected adjustments in brightness (or transient phenomena, to use astronomers’ jargon).
