It truly is simplest to spot in the Southern Hemisphere during the autumn. (Northern Hemisphere observers will want to be positioned near the equator and look for it inside the springtime.)
The Shuttle Radar Topography Mission mast was deployed productively to its total length, and the antenna was turned to its Procedure place. Following a successful checkout from the radar systems, mapping commenced at twelve:31 a.
And when they do which they run into fuel molecules, gasoline atoms, according to what it really is. And they are able to do two things. They might excite People atoms or molecules and make them emit mild, like pink mild or environmentally friendly gentle like you may see during the Aurora. Plus they may also in some cases split Those people atoms or molecules aside and make your ions and electrons.
My title is Don Gurnett. I’m an emeritus professor for the College of Iowa Department of Physics and Astronomy, in which I’ve labored for a little something near to sixty five a long time. I’ve been other destinations between, nevertheless.
HOST PADI BOYD:There’s still a whole lot to learn about this mysterious compound, particularly when you consider the amount there is out while in the observable universe.
And yeah, they’re so rarefied that you simply don’t see it from the bottom using your, along with your eye…there’s this big invisible populace.

The results of the Shuttle Radar Topography Mission was near to 1 trillion measurements of the Earth's topography. Besides contributing to the manufacture of superior maps, these measurements may lead to improved drinking water drainage modeling, extra realistic flight simulators, much better spots for cellphone towers, and Increased navigation safety.

Condition Memory Alloy Rock Splitters (SMARS) Glenn's innovative SMARS unit is fabricated from nickel-titanium-halfnium (NiTiHf), nickel-titanium-zirconium compositions, or a mixture. These compositions consist of a secondary, nanometer-sized precipitate section, which is made by way of procedures of compositional Manage and ageing heat remedies. Glenn's novel components and processes have yielded a SMA composition that produces A lot greater stresses than other SMAs around the commercial market. The SMARS device is made up of one) SMA content since the actuating member; 2) a casing heater put round the SMA member; 3) a DC or AC electrical power resource to offer recent throughout the heater; 4) pointed guidelines for acute penetration into rock formations; and five) a hand-press to reset the SMA ingredient just after each use. During the rock-splitting procedure, a hole equal into the diameter of your SMA component is drilled inside the portion of the rock where by the fracture is wished-for.
Overview Innovators at NASA's Glenn Analysis Heart have made a recreation changing, non-pneumatic, compliant tire. This innovation, called the Superelastic Tire, was made for long run Moon and Mars missions, but is really a viable option to pneumatic tires listed here on Earth. This technologies represents the latest evolution from the Spring Tire which was invented by NASA Glenn and Goodyear, and encouraged by the Apollo lunar tires. The novel usage of form memory alloys capable of undergoing substantial pressure as load bearing factors, rather than standard elastic materials, leads to a tire which can endure abnormal deformation with no everlasting injury. Making use of form memory alloy as radial stiffening features might also enhance the load carrying capacity in the tire. The nasa99 Superelastic Tire presents traction equivalent or remarkable to standard pneumatic tires and gets rid of the two the possibility of puncture failures and functioning "underneath-inflated", thereby improving upon car gasoline effectiveness and safety. Also, this tire style and design will not require an internal body which the two simplifies and lightens the tire/wheel assembly. The Technology This NASA Glenn innovation comprises a non-pneumatic, compliant tire making use of shape memory alloys (largely NiTi and its derivatives) as load bearing components.
Viewers around the globe are going to be delivered a wealth of illustrations or photos captured before, all through, and after the eclipse by 11 spacecraft, at the very least three NASA plane, more than 50 higher-altitude balloons, as well as the astronauts aboard the Worldwide Area Station – Each and every presenting a singular vantage point for that celestial celebration.
