Construction of the first prototype spaceship is in progress. "We're actually building that ship right now", he said. "I think we'll probably be able to do short flights, short sort of up-and-down flights, probably sometime in the first half of next year".
The overall outcome is that propellant different from xenon can provide significant economic benefits in the long term for commercial telecom applications. In particular, krypton would allow for a major reduction of qualification and operation costs with minor performance drawbacks.
Space Exploration Holdings, LLC seeks to modify its Ku/Ka−band NGSO license to relocate satellites previously authorized to operate at altitudes from 1110 km to 1325 km down to altitudes ranging from 540 km to 570 km, and to make related changes.This article incorporates text from this source, which is in the public domain.
As the Commission knows, SpaceX assigned its winning RDOF bids to Starlink Services, its wholly-owned subsidiary, on December 22, 2020. An intercompany agreement provides Starlink Services, LLC with access to all space and terrestrial assets and infrastructure needed from SpaceX to deploy and operate the Starlink service.
SpaceX seeks an experimental authorization to test activities ... tests are designed to demonstrate the ability to transmit and receive information (1) between five ground sites ("Ground-to-Ground") and (2) between four ground sites and an airborne aircraft ("Ground-to-Air") ... This application seeks only to use an Earth station to transmit signals to the SpaceX satellites first from the ground and later from a moving aircraft.This article incorporates text from this source, which is in the public domain.
Space Exploration Holdings, LLC seeks to modify its Ku/Ka-band NGSO license to relocate satellites previously authorized to operate at an altitude of 1,150 km (710 mi) to an altitude of 550 km (340 mi), and to make related changes to the operations of the satellites in this new lower shell of the constellationThis article incorporates text from this source, which is in the public domain.
SpaceX seeks experimental authority for two types of testing: (1) a total of 70 user terminals (mixed between the two types of antennas) so that it can test multiple devices at a number of geographically dispersed locations throughout the United States; and (2) up to 200 phased array user terminals to be deployed within the state of Washington at the homes of SpaceX employees for ongoing testing. Such authority would enable SpaceX to obtain critical data regarding the operational performance of these user terminals and the SpaceX NGSO system.This article incorporates text from this source, which is in the public domain.
SpaceX pointed out that it recently announced plans to build a network of 4,000 non-geostationary orbit (NGSO) communications satellites, which it will manufacture, launch and operate.
The system is designed to improve global Internet access by utilizing thousands of satellites in Low Earth orbit. SpaceX President Gwynne Shotwell stated in a TED Talk last month that she expects the constellation to cost at least US$10 billion. Therefore, reducing launch costs will be vital.

lower the orbit of nearly 1,600 of its proposed broadband satellites. The Federal Communications Commission said 26 April 2019 it was correct with SpaceX changing its plans to orbit those satellites at 550 km (340 mi) instead of 1,150 km (710 mi). SpaceX says the adjustment, requested six months ago, will make a safer space environment, since any defunct satellites at the lower altitude would reenter the Earth's atmosphere in five years even without propulsion. The lower orbit also means more distance between Starlink and competing Internet constellations proposed by OneWeb and Telesat. FCC approval allows satellite companies to provide communications services in the United States. The agency granted SpaceX market access in March 2018 for 4,425 satellites using Ku-band and Ka-band spectrum, and authorized 7,518 V-band satellites in November 2018. SpaceX's modified plans apply to the smaller of the two constellations.
