[33]: 44 [BR] This aeroplane was designed for sports competitions and 300 were built in several European countries and in the United States. [34]: 98 His schemes were published in the June–July 1910 issues of Popular Mechanics. [55]: 10 This plane consolidated Santos-Dumont's role in the birth of aviation in the 20th century.
Some notable powered hops were made before the problem of powered flight was finally solved. In 1874 Félix du Temple built a steam-powered aeroplane which took off from a ramp with a sailor on board and remained airborne for a short distance. This has sometimes been claimed as the first powered flight in history but the claim is generally ...
First man-made object on Mars. No contact after crash landing. Mars 3 lander: USSR: 2 December 1971: First soft landing on Mars. Transmission began about 90 seconds after landing. [4] Transmitted a partial image for 14.5 seconds before the signal was lost. [5] Mars 6 lander: USSR: 12 March 1974
The crash landing sites themselves are of interest to space archeology. Luna 1, not itself a lunar orbiter, was the first spacecraft designed as an impactor. It failed to hit the Moon in 1959, however, thus inadvertently becoming the first man-made object to leave geocentric orbit and enter a heliocentric orbit, where it remains.

Although the impacts took place on the side of Jupiter hidden from Earth, Galileo, then at a distance of 1.6 AU (240 million km; 150 million mi) from the planet, was able to see the impacts as they occurred. Jupiter's rapid rotation brought the impact sites into view for terrestrial observers a few minutes after the collisions. [34]
Artist's depiction of Pioneer 10, the first spacecraft to visit Jupiter. The exploration of Jupiter has been conducted via close observations by automated spacecraft.It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route.
Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. Its goal was to put a person into Earth orbit and return them safely, ideally before the Soviet Union. John Glenn became the first American to orbit the Earth on February 20, 1962, aboard the Mercury-Atlas 6. [57]
