Solar System space probes operational as of November 2024. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to ...
Artificial satellites and space probes in the 1990s Year Origin Name Target Status Description 1990 US/ Europe: Ulysses: Sun: Success: Ulysses solar flyby Japan: Hiten: Moon: Success: Hiten probe, this was the first non-United States or USSR probe to reach the Moon US/ Europe: Hubble Space Telescope: Earth: Success: Launch of the Hubble Space ...
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
In molecular biology, a hybridization probe (HP) is a fragment of DNA or RNA, usually 15–10000 nucleotides long, which can be radioactively or fluorescently labeled. HPs can be used to detect the presence of nucleotide sequences in analyzed RNA or DNA that are complementary to the sequence in the probe. [ 1 ]
The first probe to impact the surface of the Moon was the Soviet probe Luna 2, which made a hard landing on September 14, 1959. The far side of the Moon was first photographed on October 7, 1959, by the Soviet probe Luna 3 .s On December 24, 1968, the crew of Apollo 8 , Frank Borman , James Lovell and William Anders , became the first human ...
The structure of a typical molecular beacon probe. A typical molecular beacon probe is 25 nucleotides long. [citation needed] The middle 15 nucleotides are complementary to the target DNA or RNA and do not base pair with one another, while the five nucleotides at each terminus are complementary to each other rather than to the target DNA. A ...
A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. Space probes have different sets of scientific instruments onboard. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space.
Missions with specific targets within the Solar System (e.g., the Sun and its planets), are excluded; see List of Solar System probes for these, and List of Earth observation satellites for missions targeting Earth. Two values are provided for the dimensions of the initial orbit.
