Although communications with the satellite were lost in 1964, it remains the oldest human-made object still in orbit, together with the upper stage of its launch vehicle. [ 1 ] Vanguard 1 was designed to test the launch capabilities of a three-stage launch vehicle as a part of Project Vanguard , and the effects of the space environment on a ...
Vanguard 1. Expected to de-orbit in ~2240AD, this and its upper launch stage are the oldest human-made objects in space. Also the first use of solar cells to power a satellite. [1] 1.47 kg (3.25 lb) March 26 US: Explorer 3: Juno I: Success: Added to data received by Explorer 1. [1] 14.1 kg (31.0 lb) April 29 US: Vanguard 2A: Vanguard TV-5: Failure
Voyager 1 found that about seven percent of the volume of Saturn's upper atmosphere is helium (compared with 11 percent of Jupiter's atmosphere), while almost all the rest is hydrogen. Since Saturn's internal helium abundance was expected to be the same as Jupiter's and the Sun's, the lower abundance of helium in the upper atmosphere may imply ...

The folds mimic the natural creases found in leaves, channeling more light into the cell. The researchers claimed in 2015 that the leaf-like cells generated 47 percent more electricity than those ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
