Gravity-1 (Chinese: 引力一号) is a solid-propellant expendable medium-lift launch vehicle designed, manufactured and launched by Chinese aerospace company Orienspace. It can carry a payload of up to 6.5 tonnes (14,000 lb) to LEO or 4.2 tonnes (9,300 lb) to SSO , enabling the deployment of large-scale satellite constellations .
A gravity turn is commonly used with rocket powered vehicles that launch vertically, like the Space Shuttle. The rocket begins by flying straight up, gaining both vertical speed and altitude. During this portion of the launch, gravity acts directly against the thrust of the rocket, lowering its vertical acceleration.
The Gravity Recovery and Climate Experiment (GRACE) was a joint mission of NASA and the German Aerospace Center (DLR). Twin satellites took detailed measurements of Earth's gravity field anomalies from its launch in March 2002 to the end of its science mission in October 2017.
Space launch is the earliest part of a flight that reaches space. Space launch involves liftoff, ... If the Earth's gravity is to be overcome entirely, then ...
Its maiden flight was conducted on 11 January 2024, breaking records as both the world's largest solid-fuel carrier rocket and China's most powerful commercial launch vehicle to date. [5] Gravity-2, a partially recoverable heavy-lift launch vehicle, is expected to debut in 2025. It will be a 60-meter-tall heavy-lift rocket with a liquid-fuel ...
Gravity-1 launch in January 2024. A floating launch vehicle operations platform is a marine vessel used for launch or landing operations of an orbital launch vehicle by a launch service provider: putting satellites into orbit around Earth or another celestial body, or recovering first-stage boosters from orbital-class flights by making a propulsive landing on the platform.
In 2024, saw new world records for orbital launch attempts and successful orbital launches for the fourth consecutive year. Notable milestones included the successful maiden launches of the American Vulcan Centaur and China's Gravity-1, and Long March 12 rockets.
The gravity loss is the difference between these figures, which is gt. As a proportion of delta-v, the gravity loss is g/a. A very large thrust over a very short time will achieve a desired speed increase with little gravity loss. On the other hand, if a is only slightly greater than g, the gravity loss is a large proportion of delta-v. Gravity ...
