STS-99 also saw the recommissioning of the Spacelab pallet technique, Regardless of the Spacelab method being discontinued Just about two a long time prior.
Experts have available quite a few feasible explanations, including the intriguing recommendation that it might have been attributable to a giant Earth plunging into its mother or father star.
Also aboard Endeavour was a university student experiment known as EarthKAM, which took 2,715 electronic images in the course of the mission as a result of an overhead flight-deck window. The NASA-sponsored application allows middle faculty pupils select photo targets and get the pictures through the online world.
Stay views within the Worldwide Place Station are streaming from an external digicam mounted within the station's Harmony module. (It's possible audio only or offline solely from time to time.)
This star chart for M99 signifies the perspective from mid-northern latitudes for that offered thirty day period and time.
NASA photos and information on the eclipse will complement that gathered by other scientific corporations.
The initial of a number of “flycast” maneuvers over the mission was also created on the next working day of flight. The flycast maneuver was designed to decrease pressure about the almost-two hundred-foot mast extending from Endeavour’s cargo bay when changes to Endeavour’s orbit were required.

SMAs are superelastic in character and normally takes as much as 8% powerful reversible pressure without yielding. The SMAs can manage as many as 30x more strain, enabling the tire framework to bear high levels of deformation with out long lasting hurt. For the reason that these tires do not depend on air, the hazards linked to a flat tire are removed, and tire stiffness hardly ever varies (the tires in no way run 'below-inflated'). In addition, this airless tire layout may possibly empower the redesigning of wheel and braking programs. The initial bicycle tire prototype was approximated to have a tire stiffness comparable to a road bicycle tire inflated to 75 psi, but with improved lateral and shear stiffness. By different the SMA wire geometry, an array of tire measurements and stiffnesses is achievable. Rubber tread surfaces can be attached to the surface on the SMA tire for sufficient traction on many different terrain. Read through much more
The sole Protected technique to glance specifically at the uneclipsed or partly eclipsed Sunshine is through Specific-function photo voltaic filters, including eclipse Eyeglasses nasa99 or handheld solar viewers. Handmade filters or regular sunglasses, even very dim kinds, aren't Risk-free for thinking about the Sunshine.
NASA explores the unfamiliar in air and Room, innovates for the benefit of humanity, and conjures up the entire world by discovery.
As a way to keep the continual observations, the crew will divide right into a set of a few-human being teams to conduct two do the job shifts of twelve hrs each day. The resulting selection of knowledge is predicted to complete 9.eight terabytes -- sufficient content to fill fifteen,000 compact discs. It's going to choose scientists no less than 1 12 months to process The huge volume of knowledge recorded during the mission. No spacewalks are planned over the mission. The crew, however, will likely be geared up for the possibility of as quite a few as a few spacewalks if it gets to be required to deploy or retract portions of the radar systems manually. The crew's responsibilities contain activating the payload, deploying and stowing the mast, aligning the inboard and outboard buildings, checking payload flight units, running the on-board desktops and recorders and handling any contingencies that occur. The 97th House Shuttle start as well as the 14th flight of Endeavour will begin with a liftoff from Launch Pad 39A. Endeavour will ascend at a 57-diploma inclination to the equator for immediate insertion into orbit. The mission is scheduled for eleven days. Landing is prepared at Kennedy Place Middle's Shuttle Landing Facility.
The spacecraft is three-axis stabilized with two substantial solar arrays. It's got highly-priced nuclear hardness and survivability features which will not be included in the four Block two satellites. Crosslink functions were done at or in the vicinity of frequencies which can be absorbed by Earth's environment, protecting against detection by Earth-dependent floor stations.
NASA explores the unknown in air and space, innovates for the good thing about humanity, and evokes the earth by way of discovery.
