As of 2012 there were an estimated 500,000 pieces of debris in orbit, [4] with 300,000 pieces below 2000 km . [1] Of the total, about 20,000 are tracked. [ 1 ] Also, about sixteen old Soviet nuclear space reactors are known to have released an estimated 100,000 NaK liquid metal coolant droplets 800–900 km up, [ 5 ] which range in size from 1 ...
Boeing CST-100 Starliner for OFT-2 Arrives at SLC-41. On 9 December 2020, NASA and Boeing announced that 29 March 2021 was the targeted launch date for the OFT-2 mission. [14] [11] On 16 December 2020, Boeing officials released the official mission patch for the Orbital Flight Test-2 mission.
Comet Encke / ˈ ɛ ŋ k i /, or Encke's Comet (official designation: 2P/Encke), is a periodic comet that completes an orbit of the Sun once every 3.3 years. (This is the shortest period of a reasonably bright comet; the faint main-belt comet 311P/PanSTARRS has a period of 3.2 years.)
The company's objective is to develop a small satellite capable of capturing and moving other objects in orbit. [2] In August 2021, Starfish was awarded a Small Business Innovation Research (SBIR) contract by the U.S. Space Force to support the development of autonomous software for satellite proximity operations and docking.

USA-132, also known as GPS IIR-2 and GPS SVN-43, is an American navigation satellite which forms part of the Global Positioning System. It was the second Block IIR GPS satellite to be launched, out of thirteen in the original configuration, and twenty one overall. GPS IIR-1 failed to achieve orbit, so USA-132 was the first successful Block IIR ...
Comet C/2024 G3 has been one of the brightest comets in decades, according to EarthSky, but due to its orbit around the sun, it has been best seen by stargazers south of the equator. On Feb. 1 ...
The Air Force Research Laboratory (AFRL) is responsible for the development and execution of the DSX (originally Deployable Structures Experiment), now Demonstration & Science Experiments, also known as Space Science Technology Experiment (SSTE-4), a suite of four science payloads integrated onto a Evolved Expendable Launch Vehicle (EELV) EELV Secondary Payload Adapter (ESPA) ring based three ...
Originally planned for a December 2018 launch, [14] [28] KPLO was placed into orbit by a Falcon 9 launch vehicle on 4 August 2022. [5] Because Danuri was launched as a dedicated Falcon 9 mission, the payload along with Falcon 9's second stage was placed directly on an Earth escape trajectory and into heliocentric orbit when the second stage ...
