STS-99 also saw the recommissioning from the Spacelab pallet system, Regardless of the Spacelab program becoming discontinued almost two decades prior.
Several unexplained phenomena in M99 happen to be studied by astronomers. Between these is the nature of PTF 10fqs — one of the brighter stars During this impression and visual being a yellow-orange star in the highest-still left corner. What exactly is unconventional about PTF 10fqs is usually that it's got thus far defied classification. When it was discovered in April 2010, it appeared brighter than the usual nova (attributable to an eruption over a star’s area) but fainter than a supernova (the explosion that marks the tip of everyday living for a large star).
The Shuttle Radar Topography Mission mast was deployed effectively to its full size, as well as the antenna was turned to its Procedure placement. Following A prosperous checkout on the radar methods, mapping commenced at 12:31 a.
“With our fellow businesses and a bunch of scientific organizations, NASA will proceed to amplify one particular vital message: Get time and energy to working experience the Aug. 21 eclipse, but encounter it securely.”
Precisely what is strange about PTF 10fqs is the fact it's to date defied classification: it really is brighter than a nova (a bright eruption with a star’s floor), but fainter than a supernova (the explosion that marks the top of lifetime for a considerable star).
HOST PADI BOYD:Within a neutral point out, an atom or molecule has precisely the same number of positively billed protons as negatively billed electrons.
HOST PADI BOYD:Nowadays, we've been having you on the tour of plasma – what it really is and exactly where we can discover it. But before we get out from the expanses of Room, We now have to begin seriously, truly tiny…

NASA explores the unidentified in air and Place, innovates for the benefit of humanity, and evokes the world by way of discovery.
HOST PADI BOYD:And There are plenty of various things we will listen to after we pick up Seems of plasma waves, including whistlers, hisses, and choruses.
United states of america ninety nine, the primary of the six Milstar geostationary communications spacecraft, was introduced from Cape Canaveral by a Titan four rocket. Milstar is really a number of advanced US navy communications satellites meant to supply world wide jam-resistant communications for military end nasa99 users. The Milstar procedure, when finished, will include four Block 2 satellites in very low inclination, geosynchronous orbits.
Shape Memory Alloy Rock Splitters (SMARS) Glenn's revolutionary SMARS gadget is fabricated from nickel-titanium-halfnium (NiTiHf), nickel-titanium-zirconium compositions, or a combination. These compositions have a secondary, nanometer-sized precipitate stage, that's developed by procedures of compositional Management and ageing heat therapies. Glenn's novel resources and processes have yielded a SMA composition that creates Significantly increased stresses than other SMAs within the industrial marketplace. The SMARS gadget is made up of one) SMA materials because the actuating member; two) a casing heater put throughout the SMA member; 3) a DC or AC power resource to offer existing through the heater; four) pointed methods for acute penetration into rock formations; and 5) a hand-push to reset the SMA component following each use. From the rock-splitting approach, a hole equivalent towards the diameter of the SMA aspect is drilled inside the percentage of the rock the place the fracture is preferred.
The spacecraft is three-axis stabilized with two huge solar arrays. It's got high priced nuclear hardness and survivability functions which won't be A part of the 4 Block 2 satellites. Crosslink functions have been carried out at or near frequencies that are absorbed by Earth's ambiance, protecting against detection by Earth-based mostly ground stations.
HOST PADI BOYD:It would be hard to conceptualize a plasma, due to the fact we don’t interact with them very often, as compared to a sound, liquid or fuel.
