The Flight of Apollo 7
This documentary looks back at Apollo 7, the first manned flight of the Apollo program. Apollo 7 was designated as the essential engineering test of the spacecraft before the ambitious lunar missions could be attempted.


Running the Boston Marathon in space
NASA astronaut Suni Williams will run the Boston Marathon on a treadmill aboard the International Space Station. To preview the event, Williams, an accomplished marathoner, and Expedition 14 commander Michael Lopez-Alegria talk with The Boston Globe and the New England Sports Network.


Exercising on ISS
International Space Station Expedition 14 commander Michael Lopez-Alegria and flight engineer Suni Williams give a show-and-tell about the exercise equipment and routines aboard the orbiting complex.


STS-57: EURECA retrieved
After nearly a year in space, the European Retrievable Carrier (EURECA) satellite was plucked from orbit and stowed aboard Endeavour for return to Earth during STS-57. The June 1993 mission also featured the first flight of the commercial Spacehab module outfitted with a range of microgravity experiments for the crew to use. A spacewalk to demonstrate working on the end of the shuttle robot arm was performed as well.


STS-56: Sun and Earth
Working in two shifts around the clock, the astronauts of shuttle mission STS-56 conducted extensive observations of the Earth's atmosphere using the ATLAS 2 payload in the spring of 1993. The SPARTAN Sun-studying satellite was deployed and then retrieved during Discovery's flight too. The crew narrates the highlights in this presentation.

Proton booster delivers Canadian satellite to space

Posted: April 10, 2007

Eleven years to the day since the Russian Proton rocket began flying under the marketing banner of International Launch Services, the heavy-duty booster overnight successfully heaved a 10,200-pound Canadian telecommunications satellite into Earth orbit.

It was the 40th time an ILS-managed Proton had blasted off from the historic Baikonur Cosmodrome in Kazakhstan with a commercial satellite payload aboard. Originally formed to promote both the Proton and American Atlas rocket families, the U.S.-based firm recently reorganized to focus entirely on its Russian product offerings.

The first launch in 1996 hauled an ASTRA direct-to-home TV broadcasting satellite to serve Europe. Monday night's mission lofted the Anik F3 spacecraft, a powerful bird to be operated in geostationary orbit by Telesat Canada of Ottawa.

The extraordinarily long ascent began at 2254 GMT (6:54 p.m. EDT) as the six first stage main engines powered the 19-story rocket away from the pad 39. Tracking cameras at the cosmodrome followed the rocket's fiery golden tail flashing through the partly cloudy predawn skies of central Asia.

Within 10 minutes, the Proton had fired its three lower stages and released the Breeze M motor with the attached cargo to begin a sequence of maneuvers over the following nine hours. The five burns by the upper stage engine pushed the rocket step-by-step into the intended elliptical orbit stretching 22,200 miles at its highest point, 3,400 miles at its lowest and inclined 11 degrees to the equator.

The box-shaped satellite, with its power-generating solar arrays and antenna appendages still stowed, successfully separated from the Breeze M motor at about 0805 GMT (4:05 a.m. EDT).

Controllers will oversee several carefully-planned uses of the satellite's onboard engine to circularize the orbit where it will match Earth's rotation and appear fixed above one spot of the globe.

Anik F3's destination is a space slot at 118.7 degrees West longitude over the equator, taking Telesat's most-western orbital location, said Dan Goldberg, the company's president and CEO. That vantage point will enable the satellite to fulfill its 15-year mission to provide television, Internet and business communications across North America.

The craft should be ready to enter service next month, added Paul Bush, Telesat's vice president of broadcasting and corporate development.

European-based satellite builder EADS Astrium manufactured Anik F3 based upon the company's Eurostar E3000 design. The tri-band craft is equipped with 58 transponders -- 32 in Ku-band, 24 in C-band and two in Ka-band.

The U.S. EchoStar direct-to-home TV company will be the prime user of the Ku-band capacity. The C-band is available for high-definition TV and other broadcasting and the small Ka-band system will augment two-way Internet services already available via the Anik F2 sister satellite.

"Anik F3 will make substantial financial and operational contributions to Telesat going forward and underscores our dedication to growing our business and providing robust and reliable satellite services to citizens throughout Canada and the rest of North America," Goldberg said.

Anik F3 becomes Telesat's 17th satellite and Astrium's 33rd Eurostar in orbit. The launch marked the fourth time Telesat has used ILS Proton vehicles to deploy a satellite and the sixth Astrium E3000 to ride the Russian rocket.

"We believe that performance builds customer confidence and paves the way to long-term relationships," said Frank McKenna, the president of ILS.

The next commercial Proton launch is anticipated in June carrying a broadcasting satellite for DirecTV.
