STS-133 Webcast

The final flight of Discovery’s 26 years has been given the green light by NASA.  Lift is set for tomorrow (Wednesday, Nov 3).  This will be Discovery’s 39th lift-off, and its last.  For its last mission, Discovery will be heading to the International Space Station with a load of equipment, including a humanoid robot, Robonaut 2.

The weather forecast is holding steady with a 70 percent chance of acceptable conditions at launch time Wednesday.   Liftoff is scheduled for 3:52 p.m. EDT.

Steamed Dinosaur Eggs

A paper in Nature Communications stated certain dinosaurs created nesting habitats near geothermal vents in order to lay their eggs. Much like migratory birds, some neosauropods had specific nesting grounds. A study conducted in northern Argentina revealed that 80 clutches of dinosaur nests were located within 3 meters of geothermal conduits. This discovery assists scientists in exploring the selection and environment of dinosaur nests.

Azteca ants use similar principles to those found in velcro to capture their prey. The ants dig their claws into the rough side of their host leaf and wait for an unsuspecting grasshopper or moth to land. Scientists used weights to measure the strength of the Aztec worker ant. Results revealed they can hold 5,700 times their own body weight. The key to their strength is the surface from which they inhabit. Rough surfaces allow their claws to get a better grip and hold more weight than on smoother surfaces.

Discovery Back in Florida

The space shuttle Discovery is finally back in Florida at the Kennedy Space Center, completing its mission to the International Space Station.  Due to poor weather conditions, the shuttle landed in California on Edwards Air Force Base.  You can see Discovery and the 747 that ferried it back to Florida in the photo below.

The space shuttle Discovery will undock from the International Space Station later this afternoon.  In a final ceremony this morning, the hatches between the ISS and Discovery were sealed & preparations  for the shuttle’s return began.  Discovery is expected to land back at the Kennedy Space Center on Thursday at approximately 7:05 p.m., weather permitting.

Discovery astronaut Danny Olivas and ISS crewmember Nicole Stott will venture outside the International Space Station later today on their mission’s first spacewalk.  The spacewalk is scheduled to begin at 5:49 p.m. EDT.  The two astronauts main task will be the removal of an old ammonia coolant tank that cools the systems on the ISS.  The tank is scheduled to be replaced on Thursday.

The space shuttle Discovery docked with the International Space Station yesterday evening.  The smaller steering jets began leaking after liftoff on Friday and were shut down.  This meant that shuttle commander Frederick “C.J.” Sturckow was forced to use Discovery’s big maneuvering thrusters to guide Discovery into dock.  But, Sturckow was able to dock Discovery with only a little more noise & bumping than a typical dock.  While the commander had been trained on this docking method, this was his first time performing this type of dock.
