Copenhagen Suborbitals is the world’s only manned, amateur space program, 100% crowdfunded and nonprofit. In the future, one of us will fly to space on a home built rocket. Support the project!

The constellation of WGS satellites increases the communications capabilities of the militaries of the United States, Canada, and Australia by providing additional bandwidth and communications capabilities for tactical command and control, communications, and computers; intelligence, surveillance, and reconnaissance (C4ISR); battle management; and combat support information. Canada has also signed on to become a partner.
WGS also augments the current Ka-band Global Broadcast Service (on UHF F/O satellites) by providing additional information broadcast capabilities as well as providing new two-way capability on that band. It provides services to the US DoD and Australian Department of Defence. The IWS System supports continuous 24-hour-per-day wideband satellite services to tactical users and some fixed infrastructure users. Limited protected services will be provided under conditions of stress to selected users employing terrestrial modems capable of providing protection against jamming.

Northrop Grumman’s Antares rocket launched April 17 from the Wallops Flight Facility, Virginia, carrying the unpiloted Cygnus cargo spacecraft to orbit for its journey to deliver several tons of supplies and scientific experiments to the International Space Station. Dubbed the “SS Roger Chaffee” in honor of the NASA astronaut who died in the Apollo 1 launch pad fire in January 1967, Cygnus is scheduled to arrive at the station on April 19. It will remain at the space station until July 23, when it will depart, deploy NanoRacks customer CubeSats, and then have an extended mission in orbit until December. This will be the final mission under Northrop Grumman’s Commercial Resupply Services (CRS-1) contract with NASA before starting the CRS-2 contract missions this fall.

Three of the world’s largest radio telescopes team up to show a rare double asteroid. 2017 YE5 is only the fourth binary near-Earth asteroid ever observed in which the two bodies are roughly the same size, and not touching. This video shows radar images of the pair gathered by Goldstone Solar System Radar, Arecibo Observatory and Green Bank Observatory.

Northrop Grumman has made significant progress in developing its new satellite life extension service. The innovative technology, a first in the industry, gives satellite operators the capability to extend the life of a healthy satellite. Northrop Grumman remains on track to introduce its in-orbit satellite servicing system with the Mission Extension Vehicle-1 (MEV-1).
