On August 16, 2010 American astronauts Douglas Wheelock and Tracy Caldwell Dyson completed the third contingency spacewalk to install a spare ammonia pump module on the S1 Truss.
Flight Engineer Shannon Walker assisted the spacewalkers from inside the International Space Station and operated the Canadarm2. Flight Engineers Wheelock and Caldwell Dyson were outside during the third repair spacewalk for 7 hours and 20 minutes.
On August 14, 2010 at 11:07 UTC the Atlas-5 (AV-019) rocket-carrier was launched by United Launch Alliance from Cape Canaveral's Complex 41.
The rocket-carrier orbited the AEHF 1 (Advanced Extremely High Frequency 1) military communication satellite.
A sophisticated satellite was launched to improve the communications between the president, military commanders and troops on the battlefield, ensuring a survivable line of contact even in hellish scenarios of nuclear warfare.
On August 11, 2010 American astronauts completed the second of three spacewalks to fix a failed cooling pump on the International Space Station (ISS).
During the spacewalk, which lasted 7 hours and 26 minutes, Expedition 24 Flight Engineers Tracy Caldwell Dyson and Douglas Wheelock removed the failed ammonia coolant pump module.
One of two cooling systems serving the ISS broke down late on July 31, and the crew had shut down several pieces of equipment, including two of the station's four gyroscopes, to cut the heat generated on board.
On August 9, 2010 at 22:49 UTC (on August 10, 2010 at 06:49 a.m. Beijing Time) China successfully launched the Long March 4C (Chang Zheng-4C) rocket-carrier from the Taiyuan Satellite Launch Center in northern Shanxi Province.
The rocket orbited the "Yaogan 10" remote-sensing satellite.
The satellite will be used to conduct scientific experiment, carry out surveys on land resources, estimate crops yield and help with natural disaster-reduction and prevention endeavor.
On August 4, 2010 at 20:59 UTC the Arian 5 rocket-carrier was launched from the French Cosmodrome in Kourou, French Guiana.
The rocket-carrier orbited 2 African communications satellites.
Both satellites were built by Thales Alenia Space of France.
The Nilesat 201 satellite will enter service at 7 degrees west longitude, joining two other Nilesat spacecraft and a European-owned satellite to provide direct-to-home television, radio and broadband Internet services to Africa and the Middle East.
The Rascom-QAF 1R satellite will be stationed at 2.85 degrees east longitude with 12 C-band and eight Ku-band transponders, beaming television, telephone and Internet services across Africa.

On July 27, 2010 Russian cosmonauts Fiodor Yurchikhin and Mikhail Kornienko performed the extra vehicle activities (EVA – space walk).
The cosmonauts installed a new TV-camera which is to monitor ATV rendezvous and docking to the Zvezda module of the Russian segment of the ISS. They also connected the "Rassvet” module’s control and data harness to the "Zarya” module, and laid Kurs system cabling between the 2 modules (Rassvet and Zarya).
