HOUSTON — NASA and SpaceX, the agency’s front-running Commercial Orbital Transportation Services (COTS) partner, declared themselves ready for a late April launching of the first privately developed cargo mission to the International Space Station, following an April 16 Flight Readiness Review (FRR).

HOUSTON — NASA is looking to firm up future Mars exploration options by August, as the agency rebounds from a proposed 20% cut in the planetary exploration program that forced it to withdraw from a budding partnership with the European Space Agency (EGSA) for the ExoMars missions in 2016 and 2018. Though the long-term federal funding outlook is uncertain, NASA’s recently established Mars Program Planning Group (MPPG) is looking at perhaps $700-800 million for either a lander or an orbital mission launch in 2018 or 2020.

HEAT VISION: Lockheed Martin has completed assembly of the Near Infrared Camera (NIRCam) for NASA’s James Webb Space Telescope, the company announced April 16. The work was done at the Lockheed Martin Space Systems Advanced Technology Center in Palo Alto, California, where environmental testing is about to begin. The University of Arizona and Lockheed Martin are responsible for the NIRCam instrument design, the instrument control and focal plane electronics and software.

PARIS — The Yahsat 1B (Y1B) telecom satellite owned by United Arab Emirates-based Al Yah Satellite Communications Co. is slated to launch April 24 aboard an International Launch Services Proton rocket from Baikonur Cosmodrome, Kazakhstan. When Y1B enters service, it will complete the two-spacecraft Yahsat system built by EADS-Astrium and Thales Alenia Space. Al Yah, however, is now considering ordering a third satellite and is soliciting interest from numerous manufacturers, according to industry officials.

HANDED OVER: Three months after its launch, the U.S. Air Force has accepted control of WGS-4 following Boeing’s in-orbit testing of the spacecraft, which is based on the 702HP commercial satellite bus. WGS-4 will be the first Block II in operation following USAF acceptance testing. Block II spacecraft feature three times faster data rate transmissions of airborne intelligence, surveillance and reconnaissance imagery as compared to Block I. WGS-5 is in production and due for launch in 2013. The WGS is the successor to the Defense Satellite Communications System.

With the ability of heavy-lift rockets to do piggy-back launches, it is surprising to learn that even after making 100 A2100 geosynchronous communications satellites since 1996, Lockheed Martin has yet to see two of the spacecraft launched on the same ride. That string is set to be broken May 15 when the 100th and 101st satellites in the series, JCSat-13 and Vinasat-2, are to be lofted by an Ariane 5 from Arianespace’s launch facility in Kourou, French Guiana. The two spacecraft were shipped to Kourou on April 12.

HOUSTON — A European Space Agency (ESA) inquiry points to a still-unexplained problem with a computer communications interface as the culprit in a temporary power loss that followed the recent docking of the cargo- and propellant-laden Automated Transfer Vehicle-3 with the International Space Station.

Calling optical systems “the next era of space communications,” NASA’s Goddard Space Flight Center has selected Space Systems/Loral (SS/L) to host a laser communications relay demonstration (LCRD) payload on a 2016 commercial mission. The technology has two attractions: optical communications use an uncongested portion of the spectrum compared to the radio frequencies that currently transmit data from space; and they hold the promise of orders of magnitude higher data rates than RF communications.
