Due to its large size, the timeline has been split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951. The list for the year 2025 and for its subsequent years may contain planned launches, but the statistics will only include past launches.
This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: It includes: All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes .
Albert II, a rhesus monkey, became the first mammal in space aboard a U.S. V-2 rocket on June 14, 1949, and died on reentry due to a parachute failure. The first dogs in space were launched 22 July 1951 aboard a Soviet R-1V. "Tsygin" and "Dezik" reached a height of 100 km (62 mi) and safely parachuted back to Earth.
Demonstrate low-thrust plasma propulsion in deep space. BioSentinel: Heliocentric Operational Contains yeast cards that will be rehydrated in space, designed to detect, measure, and compare the effects of deep space radiation. LunaH-Map: Moon Failure Search for evidence of lunar water ice inside permanently shadowed craters using its neutron ...
The rapid expansion of space meant that elementary particles remaining from the grand unification epoch were now distributed very thinly across the universe. However, the huge potential energy of the inflaton field was released at the end of the inflationary epoch, as the inflaton field decayed into other particles, known as "reheating".
Scientists say comet C/2023 A3 Tsuchinshan-ATLAS is visible once every 80,000 years, and people across North America were treated to stunning views.
The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The reform advanced the date by 10 days: Thursday 4 October 1582 was followed by Friday 15 ...
