(1) A lunar lander

(2) This set includes toy models of Sojourner, the Pathfinder spacecraft, and a lander .

(3) Rosetta is the first probe ever designed to enter orbit around a comet's nucleus and release a lander onto its surface.

(4) Rosetta will reach the comet in 2014, enter into orbit and deliver a lander , Philae, onto the surface.

(5) A lunar lander

(6) Twenty seconds later, it will jettison the bottom half of its aeroshell, exposing the lander .

(7) The command ship accommodated three astronauts and the lunar lander only two.

(8) There are no blast craters under the lunar landers .

(9) Without atomic clocks, GPS navigation would be impossible, the Internet would not synchronize, and the position of the planets would not be known with enough accuracy for space probes and landers to be launched and monitored.

(10) It comprised of three different modules, and was similar in design to previous Moon landers .

(11) The Surveyor lunar landers followed in the late 1960s, which dramatically helped in the site selection for the Apollo landings.

(12) They may involve several independent elements, such as orbiters, sub-satellites, landers , rovers, penetrators, airborne robots, planetary ascent vehicles or re-entry vehicles.

(13) A U.S. contribution to the French-led NetLander mission will add unique capabilities to each of the four landers and the orbiter which comprise the mission.

(14) The Lunar module itself, carrying four astronauts, will settle on the surface of the Moon much like the old Apollo landers .

(15) This smart software can be used on all kinds of spacecraft, including orbiters, landers and rovers.

(16) Having no proven track record with Mars spacecraft themselves, let alone Mars landers , ESA asked the Jet Propulsion Laboratory to evaluate Beagle 2.

(17) Moreover, while China has discussed developing a rudimentary space station, there is no evidence of the development of spacecraft, like landers , needed for lunar missions.

(18) This capability will serve both to relay detailed findings of the instruments on the orbiter and enable data relay from other landers on the Martian surface to Earth.

(19) Genesis is the first mission to return samples from space to Earth since the Apollo astronauts and Soviet robotic landers brought home hundreds of pounds of Lunar rocks in the 1970s.

(20) A mission involving three gliders would explore the composition and stratigraphy of the walls of Valles Marineris in ways not possible for orbiters and landers .

(21) Each satellite would carry a shortrange UHF transceiver to communicate with landers and orbiters near Mars and a longrange radio to relay information back to Earth.

(22) While the Viking orbiters were revealing mysteries from high above, two landers sent to the surface by the spacecraft set about chronicling the surface conditions in detail for the first time.
