EVRY, France (Arianespace PR) — Arianespace announced today that it will launch BSAT-4b, under the term of a turnkey contract between B-SAT and Maxar’s SSL.
BSAT-4b will be launched by an Ariane 5 in 2020 from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana, as part of a turnkey contract between the Japanese satellite operator B-SAT and the California-based satellite manufacturer SSL.
The world’s launch providers have been extremely busy in the first quarter of 2018, with 31 orbital launches thus far. This is more than one third of the 90 launches conducted last year.
China leads the pack with 10 successful launches. The United States is close behind with a total of nine launches with one failure. The tenth American launch is scheduled for Monday afternoon from Florida.

Most travel books promote exciting locales such as Paris, Machu Pichu or Bali that people actually want to visit to relax and escape the pressures of life in the 21st century.
Joe Pappalardo had a different idea for his travelogue. The contributing editor for Popular Mechanics decided to visit various spaceports and rocket test sites to gauge how commercial space is transforming the industry.
Pappalardo’s travels take him from the sandy beaches of Florida and Virginia to the desolate deserts of the American Southwest and steaming jungles of French Guiana. Along the way, we meet everyone from Elon Musk to the crew at Masten Space Systems and the local gentry in the various towns adjoining these facilities.
It was a successful week for launches around the world.
On Tuesday, SpaceX conducted its 50th launch of the Falcon 9 rocket. The booster orbited the 30W-6 communications satellite for Hispsat of Spain from Cape Canaveral Air Force Base in Florida. At 6 metric tons, it was the heaviest geosynchronous satellite ever launched by SpaceX.
On Friday, a Soyuz booster roared off the pad in French Guiana to deliver four O3b F4 communications satellites for SES. It was the third successful launch of Russia’s workhorse Soyuz rocket this year.
Below is the current launch schedule for March. In total, there are 8 launches planned for the month with 16 communications satellites, one meteorological satellite, and one crew mission to the International Space Station. The launches include:
PARIS, 2 March 2018 (ESA PR) — After the release of the conclusions of the Ariane VA241 Independent Enquiry Commission on 22 February, the findings and recommendations were formally presented to a Steering Board on 28 February. The board included Daniel Neuenschwander, ESA Director of Space Transportation; Stéphane Israël, Arianespace CEO; and Alain Charmeau, ArianeGroup CEO.
Bad Coordinates Placed Satellites in Incorrect Orbits
EVRY, France (Arianespace PR) — The Independent Enquiry Commission formed after the Ariane 5 launcher’s trajectory deviation during its January 25, 2018 mission issued its conclusions on Thursday, February 22. The anomaly’s cause is perfectly understood and recommendations are clearly identified.
An Ariane 5 booster delivered two communications satellites into the wrong orbits on Thursday, but their owners say the spacecraft are healthy and will be able to reach their intended destinations using on-board propulsion.
UPDATE: Agence France Presse (AFP) is reporting the problem with Ariane 5 involved more than just a loss of telemetry:
But a source told AFP the satellites did not detach from the rocket in the correct place after the craft followed an “imperfect trajectory”.
Arianespace said they were currently “repositioning the satellites in the right place using their propulsion systems” adding that the current status was “reassuring after strong concerns”.
I don’t see any further updates on the mission on the websites of Arianespace, SES or Yahsat. This leads me to believe the AFP report is accurate. If it had been a simple telemetry loss, Arianespace would have said so, and there would be press releases and social media messages declaring the flight to be a complete success.
Yahsat does have a link to a page with an update about the mission. It’s in Arabic so I ran it through Google Translate. The update doesn’t appear to go beyond Arianespace’s original statement about the spacecraft separating from the second stage and being in contact with control centers. ________
Controllers lost contact with the upper stage of an Ariane 5 booster carrying a pair of communications satellites on Thursday. The loss telemetry began a few seconds after ignition of the stage and continued through the rest of the powered flight, Arianespace said in a statement.
“Subsequently, both satellites were confirmed separated, acquired and they are on orbit,” the company said. “SES-14 and Al Yah 3 are communicating with their respective control centers. Both missions are continuing.”
The precise orbital parameters of the geosynchronous communications satellites are unknown. SES-14 will use electric propulsion to reach its intended orbit while the Al Yah 3 will use a liquid bi-propellant transfer system.
Earlier on Thursday, China launched the fourth group of three Yaogan Weixing-30 satellites. A Long March 2C booster flew from the Xichang Satellite Launch Center.
Officially, the Yaogan Weixing are remote sensing spacecraft. However, analysts believe they are military reconnaissance satellites.
The flight marked China’s fifth successful launch of 2018. The nation is aiming to achieve more than 40 orbital launches this year.
EVRY, France 9 (Arianespace PR) — The past year saw Arianespace carry out 11 successful launches; sign 19 additional launch contracts, including three for Vega C and two for Ariane 6; and enter a new governance structure alongside ArianeGroup.
Building on these achievements, Arianespace is targeting a record number of launches in 2018, while actively focusing on the next decade with its Ariane 6 and Vega C launchers. (more…)
EVRY, France (Arianespace PR) — Arianespace signed an agreement to launch two satellites for longtime customer Intelsat, one of the world’s largest satellite operators. This continues the longstanding relationship between Intelsat and Arianespace that dates back to 1983.
The first launch will carry the Galaxy 30 satellite together with the Orbital ATK Mission Extension Vehicle-2 (MEV- 2) as a stacked pair. Galaxy 30 will be the first replacement satellite for the North American Galaxy Fleet and in addition to its C-band payload, Galaxy 30 will include Ku- and Ka-band payloads to support broadband applications in North America. The launch of Galaxy 30 demonstrates Intelsat’s commitment to its distribution neighborhoods, which has an unmatched penetration of cable headends in the United States. Galaxy 30 is based on Orbital ATK’s GEOStar-2™ satellite platform.
EVRY, France (Arianespace PR) — With this latest order, there are now 23 Ariane 5 launchers in production or to be produced, from the PB+ and PC batches. With this latest “PC batch,” the industry confirms its commitment to consolidate the competitiveness of the European launch offer even before the arrival of Ariane 6.
ArianeGroup and its Arianespace subsidiary have announced an order for 10 Ariane 5 ECA launchers. The 10 launch vehicles covered by this “PC batch” will be deployed from the Guiana Space Center beginning in 2020, coming after the launches of 18 Ariane 5s ordered in 2013 (in the “PB+ batch”). This production order represents a total value of more than one billion euros for the European space industry, involving more than 600 companies in 12 European countries* – including 350 small and medium-sized enterprises.
SpaceX had a banner year in 2017, launching a record 18 times and helping to propel the United States to the top of the global launch table with a perfect 29-0 record. The U.S. total made up 32.2 percent of 90 orbital launches worldwide, which was an increase over the 85 flights conducted in 2016.
The 29 American launches were a leap of seven over the 22 flights conducted the previous year. This is the highest number of American orbital launches since the 31 flights undertaken in 1999. However, that year the nation’s launch providers suffered four failures whereas they were perfect in 2017.
