Very low Earth orbit is a range of orbital altitudes below 400 km (250 mi), and is of increasing commercial importance in a variety of scenarios and for multiple applications, in both private and government satellite operations.
BlackSky, at $338 million in market capitalization, is arguably the cheapest of these three stocks. With 16 satellites in orbit, BlackSky operates as an Earth observation (i.e. spy satellite) company.
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. [1]
EagleEye is an Earth observation satellite in very low Earth orbit. It is the first satellite developed and operated by the Polish Space Agency (POLSA), as previous Polish satellites, PW-Sat , BRITE , and Intuition-1 , were designed and operated by private firms.
To get a Starship lander to the moon, SpaceX must first get it into low-Earth orbit, then launch multiple Super Heavy-Starship "tankers" to refuel the moon-bound Starship for the trip to lunar orbit.
In low-earth orbit, objects can collide at around 23,000 miles an hour, enough for even the tiniest debris to crack the windows on the International Space Station. Nearly 30,000 objects are ...
Super Low Altitude Test Satellite (SLATS) or Tsubame was a JAXA satellite intended to demonstrate operations in very low Earth orbit (VLEO, below 200 km), using ion engines to counteract aerodynamic drag from the Earth's atmosphere which is substantial at such lower orbital altitudes. It was launched on 23 December 2017, and decommissioned on 1 ...
If China becomes the only permanent presence in space, international partners could be forced to rely on Taikonauts for long-term needs in low Earth orbit. Commercial companies could also be ...
