The NASA MESSENGER spacecraft has managed to stop their march and enter orbit around mercury, a historic achievement because no other spacecraft earlier had tried. The vehicle, which already had sent the world numerous information of the planet during the previous flybys, can now devote to get continuously high resolution of surface data.
The MESSENGER faced its last two days of travel by running an automatic sequence of approximation. March 15, controllers verified that all the maneuvers, guidance and trajectory adjustments had been carried out properly, and that the high-gain antenna of the spacecraft turned to point toward Earth. Through it all telemetry receives prior to starting the engine. Also, went out all the scientific instruments on board to avoid interference, except the gamma ray spectrometer, which remain latent for ensuring the thermal stability of the cryogenic cooling system. If all went well, the instruments would be connected again from day 23. Read the rest of this entry »
The Discovery shuttle crew used the two extra days either aboard the international space station. Before returning to Earth, astronauts completed the activation of the module Leonardo and completed the transfer of cargo between the two vehicles.
On Friday March 4 was devoted almost entirely to work within the Leonardo. Various machine elements unpacked and extracted other experiments Platform Express Rack 8 for relocation and the Destiny module.
They also had time to talk to several students at the Marshall Space Flight Center and talk to the press. Finally, we kept the tools that were used during the two previous spacewalks.
During the next day, the tenth of the mission, he continued the work within the module Leonardo. Removed packaging material, used to secure items during takeoff, and took it to the Kounotori2, the Japanese logistics vehicle that will burn away when re-entered Earth’s atmosphere.

After the last trip space mission, Discovery’s crew spent the March 3 in a much more relaxed. In addition to continue to prepare to use the new module PMM, received the call from President Obama.
NASA astronauts gave a well-deserved half-day rest, although the first part of the day was dedicated to continue to transfer items from the shuttle Discovery and the station, and vice versa. Up to 76 percent of the transfers had already completed at the beginning of the day.
The crew participated in two television appearances, in addition to carrying out any maintenance. Scott Kelly, and Cady Coleman, for example, reviewed the CO2 removal facilities in the U.S. segment, to ensure that everything goes well. The Russian equivalent, Vozdukh system had to be stopped temporarily for some repairs. Read the rest of this entry »
