STS-ninety nine also saw the recommissioning of the Spacelab pallet procedure, Regardless of the Spacelab program becoming discontinued almost two yrs prior.
NASA explores the unknown in air and Place, innovates for the benefit of humanity, and evokes the world by way of discovery.
Also aboard Endeavour was a scholar experiment known as EarthKAM, which took two,715 digital images throughout the mission by an overhead flight-deck window. The NASA-sponsored system allows Center college pupils choose Picture targets and acquire the images by means of the Internet.
Hi, I’m Doug Rowland. And I’m a scientist learning the Earth’s upper ambiance. Which’s a fascinating area, since it’s in which the Earth’s atmosphere that we breathe, turns right into a fuel identified as plasma that’s electrically billed.
Mapping proceeded rather smoothly, but through an Mindset-maintain interval for payload mapping in the course of the 2nd working day of flight, it was determined that orbiter propellant utilization experienced doubled from 0.
This Hubble graphic was manufactured in June 2010, through the interval if the outburst was fading, so PTF 10fqs’s place can be pinpointed with wonderful precision. These measurements will allow other telescopes to household in within the star in upcoming, even if the afterglow of the outburst has pale to nothing.
HOST PADI BOYD: Don Gurnett has put in his job researching plasmas and plasma physics. To start discussing plasmas, you have to start with a gas. And to turn that gas into a plasma, we’ve got to add a little bit of Power.
This triggered the mast to deflect a little bit backwards then rebound ahead. As it attained vertical, a more robust thrust was used, arresting the mast's movement and increasing the orbiter's speed.
SMAs are superelastic in character and normally takes as much as 8% powerful reversible pressure without the need of yielding. The SMAs can deal with around 30x additional pressure, allowing for the tire structure to endure large levels of deformation with no lasting destruction. Because these tires don't count on air, the hazards linked to a flat tire are eradicated, and tire stiffness in no way varies (the tires in no way run 'under-inflated'). Furthermore, this airless tire design may perhaps help the redesigning of wheel and braking devices. The 1st bicycle tire prototype was approximated to have a tire stiffness comparable to a highway bike tire inflated to seventy five psi, but with enhanced lateral and shear stiffness. By varying the SMA wire geometry, a variety of tire measurements and stiffnesses is achievable. Rubber tread surfaces could possibly be attached to the skin on the SMA nasa99 tire for sufficient traction on a variety of terrain. Browse far more
NASA and other businesses will deliver important facts and updates on their own respective Internet sites which include viewing protection, actions across the country which include at countrywide parks, in addition to transportation preparations.

Hubble’s most notable scientific discoveries replicate the wide variety of analysis as well as the breakthroughs it has achieved.
Overview Innovators at NASA's Glenn Analysis Heart have formulated a activity changing, non-pneumatic, compliant tire. This innovation, called the Superelastic Tire, was created for potential Moon and Mars missions, but can be a feasible different to pneumatic tires below in the world. This know-how signifies the newest evolution on the Spring Tire which was invented by NASA Glenn and Goodyear, and motivated with the Apollo lunar tires. The novel utilization of shape memory alloys capable of going through significant strain as load bearing elements, rather than common elastic materials, brings about a tire which can face up to extreme deformation with out long term destruction. Applying form memory alloy as radial stiffening components can also enhance the load carrying ability from the tire. The Superelastic Tire features traction equivalent or exceptional to standard pneumatic tires and removes both the opportunity of puncture failures and working "under-inflated", therefore enhancing vehicle fuel effectiveness and safety. Also, this tire style and design will not involve an inner body which both simplifies and lightens the tire/wheel assembly. The Know-how This NASA Glenn innovation comprises a non-pneumatic, compliant tire utilizing form memory alloys (mainly NiTi and its derivatives) as load bearing elements.
Viewers throughout the world will be supplied a wealth of photos captured ahead of, through, and once the eclipse by eleven spacecraft, no less than 3 NASA aircraft, a lot more than 50 large-altitude balloons, as well as the astronauts aboard the Worldwide Room Station – Every single giving a unique vantage stage for the celestial event.
