2021 In Spaceflight
The year 2021 broke the record for the most orbital launch attempts till then (146) and most humans in space concurrently (19) despite the effects of COVID-19 pandemic. Overview Astronomy and astrophysics The IXPE telescope was launched on a Falcon 9 on 9 December 2021. The long-delayed James Webb Space Telescope, the largest optical space telescope ever built, was launched to the Sun–Earth point by a European Ariane 5 rocket on 25 December 2021. Planetary science Spacecraft from three Mars exploration programs from the United Arab Emirates, China, and the United States (Hope, Tianwen-1, and Mars 2020) arrived at Mars in February. The '' Perseverance'' rover landed on 18 February. As part of the Mars 2020 mission, the '' Ingenuity'' solar-powered drone performed the first powered aircraft flight on another planet in human history. It has a communications link with the ''Perseverance'' rover and used autonomous control during its short scripted flights. The ' ...

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microgravity
Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) or, incorrectly, zero gravity. Weight is a measurement of the force on an object at rest in a relatively strong gravitational field (such as on the surface of the Earth). These weight-sensations originate from contact with supporting floors, seats, beds, scales, and the like. A sensation of weight is also produced, even when the gravitational field is zero, when contact forces act upon and overcome a body's inertia by mechanical, non- gravitational forces- such as in a centrifuge, a rotating space station, or within an accelerating vehicle. When the gravitational field is non-uniform, a body in free fall experiences tidal forces and is not stress-free. Near a black hole, such tidal effects can be very strong, leading to ''spaghettification''. In the case of the Earth, the effects are minor, especiall ...

Q-PACE
CubeSat Particle Aggregation and Collision Experiment (Q-PACE) or Cu-PACE, was an orbital spacecraft mission that would have studied the early stages of proto-planetary accretion by observing particle dynamical aggregation for several years.NASASmall Innovative Missions for Planetary Exploration Program Abstracts of selected proposals August 8, 2015. Retrieved Nov. 17, 2022. Current hypotheses have trouble explaining how particles can grow larger than a few centimeters. This is called the meter size barrier. This mission was selected in 2015 as part of NASA's ELaNa program, and it was launched on 17 January 2021. As of March 2021, however, contact has yet to be established with the satellite, and the mission was feared to be lost. The mission was eventually terminated. Overview Q-PACE was led by Joshua Colwell at the University of Central Florida and was selected NASA's CubeSat Launch Initiative (CSLI) which placed it on Educational Launch of Nanosatellites ELaNa XX. ...

PICS (satellite)
Passive Inspection CubeSats, or PICS, is a technology demonstration spacecraft mission utilizing two CubeSat miniaturized satellites, identified as ''PIC-A'' and ''PIC-B''. The project was developed by students at Brigham Young University (BYU) as part of NASA's Educational Launch of Nanosatellites (ELaNA) initiative beginning in 2016. The satellites are outfitted with cameras to be able to get a 360-degree view to visually assess the exterior of other spacecraft and detect possible damage. BYU professor David Long termed the project a "spacecraft selfie cam." PIC-A and PIC-B were originally scheduled to be launched in 2018, but launch was delayed until 2021. PICs was successfully launched into orbit along with eight other CubeSats during Virgin Orbit's Launch Demo 2 on January 17, 2021.
