Institution: NASA; Primary mission completion: November 1980; Current trajectory: entered interstellar space August 2012; Voyager 2. Mission: studying all four giant planets. This mission was one of NASA's most successful, yielding a wealth of new information. As of November 2017 it is some 116 AU from the Sun (17.34 billion kilometers). [14]
True color image of the Earth from space. This image is a composite image collected over 16 days by the MODIS sensor on NASA’s Terra satellite. NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019.
The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
Sun–Earth L 1: ESA, NASA: Orbiting near L 1 since 1996. Operational as of 2020. [27] WIND: Sun–Earth L 1: NASA: Arrived at L 1 in 2004 with fuel for 60 years. Operational as of 2019. [28] Wilkinson Microwave Anisotropy Probe (WMAP) Sun–Earth L 2: NASA: Arrived at L 2 in 2001. Mission ended 2010, [29] then sent to solar orbit outside L 2. [30]
The larger piece of space debris had carbon fiber composite and honeycomb structure, weighing nearly 100 pounds (45 kg). It was part of the Axiom 3 Dragon trunk section that reentered on 26 February over that region. [57] [58] On 21 May 2024, a fragment of reentered space debris was found in Haywood County (North Carolina, US). The charred ...
Earth Observing-1 (EO-1) was a NASA Earth observation satellite created to develop and validate a number of instrument and spacecraft bus breakthrough technologies. It was intended to enable the development of future Earth imaging observatories that will have a significant increase in performance while also having reduced cost and mass.
Human presence in outer space began with the first launches of artificial object in the mid 20th century, and has increased to the point where Earth is orbited by a vast number of artificial objects and the far reaches of the Solar System have been visited and explored by a range of space probes.
[1] [7] In 2019, the Planetary Defense Coordination Office decided to fund this mission outside NASA's science budget due to its national security implications. [9] [10] On 11 June 2021, NASA authorized the NEO Surveyor mission to proceed to the preliminary design phase. [11] The Jet Propulsion Laboratory will lead development of the mission. [1]
