NASA is working on a modelling study that considers the asteroid 101955 Bennu, which has a diameter of 246 meters and capable of a 1.15 gigaton impact, as a modelling target for the HAMMER concept. [ 4 ] [ 5 ] It is circling the Sun at 63,000 mph and 54 million miles from the Earth .
Athena was a proposed space mission that would have performed a single flyby of asteroid 2 Pallas, the third largest asteroid in the Solar System. [1] If Athena had been funded, it was planned to share the launch vehicle with the Psyche and Janus spacecraft and fly its own trajectory for a Mars gravity assist to slingshot into the asteroid belt.

Falcon 9 Block 5, the most prolific active orbital launch system in the world. This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list ...
The Energia launcher was designed by the Soviet Union to launch up to 105 t (231,000 lb) to low Earth orbit. [8] Energia launched twice in 1987/88 before the program was cancelled by the Russian government , which succeeded the Soviet Union, but only the second flight payload reached orbit.

Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
