Ariane 5 launches two satellites

7:23 am

Arianespace yesterday successfully placed a South Korean weather satellite and an Indian communications satellite into orbit using its Ariane 5 rocket.

The Indian satellite was initially supposed to launch in the spring, but ISRO pulled it back to India just after its arrival in French Guiana to do more checks on it because of the failure of another satellite using similar components.

The leaders in the 2018 launch race:

33 China
19 SpaceX
13 Russia
10 Europe (Arianespace)
8 ULA

Arianespace had predicted it would do 14 launches this year. As this launch is described as its last 2018 launch, it appears they have fallen short of that prediction.

These standings will be updated later today, assuming SpaceX’s Dragon launch to ISS goes off as scheduled.

Soyuz from French Guiana successfully launches weather satellite

6:00 pm

A Russian Soyuz rocket tonight successfully launched a European weather satellite from French Guiana.

This success once again indicates that the manned Soyuz launch in December to ISS can take place as scheduled.

Though this was a Russian rocket, I count it as a Arianespace launch, as it is launched from their launchpad. Arianespace is also the operator and sales agent for the rocket. Obviously, this is open to interpretation.

The leaders in the 2018 launch race:

31 China
17 SpaceX
10 Russia
8 ULA
8 Europe (Arianespace)

China remains the leader in the national rankings, 31 to 26 over the U.S.

Ariane 5 launches BepiColumbo to Mercury

12:48 am

An Arianespace Ariane 5 rocket successfully launched the joint European/Japanese BepiColumbo mission to Mercury this weekend.

BepiColombo consists of two orbiters: Japan’s Mercury Magnetospheric Orbiter (MMO) and ESA’s Mercury Planetary Orbiter (MPO), both of which will be carried together by the Mercury Transport Module (MTM).

While MPO will go into an approximately 400 x 1500 km mapping orbit around Mercury, MMO will enter a highly elliptical orbit to study the planet’s enigmatically strong magnetic field.

The leaders in the 2018 launch race:

28 China
17 SpaceX
8 Russia
8 ULA
7 Europe (Arianespace)

China still leads the U.S. in the national rankings 28 to 26.

Ariane 6 gets first commercial contract

8:38 am

Capitalism in space? Arianespace yesterday signed its first commercial contract for its new rocket, Ariane 6.

The Sept. 10 contract is Arianespace’s first with a commercial satellite operator for Ariane 6, and brings to eight the number of Ariane 6 missions on the company’s manifest, assuming none of the Eutelsat satellites are dual-manifested on the same rocket.

Eutelsat executives have suggested for years that the company was willing to be first in line to embrace Ariane 6, including most recently in June 2017 when the company signed a three-launch agreement for Ariane 5 missions.

Eutelsat spokesperson Marie-Sophie Ecuer told SpaceNews by email that the multi-launch agreement came with “attractive terms” that are “fully aligned with our objective to significantly reduce launch cost,” but declined to say if the company received a discount. To woo customers, SpaceX offered discounts of around $10 million to launch on the first Falcon 9 rockets to use previously flown first-stage boosters.

I question the private nature of this deal, in that Eutelsat is a European company with many legal ties to the European Union. Since all reports I’ve seen suggest that Ariane 6 is not going to be as cheap as SpaceX’s rockets, I wonder if some political pressure has been applied to Eutelsat to sign this contract.

Overall, it increasingly appears to me that Ariane 6 will not get much business outside of Europe because of its cost. Much like Russia, Europe is giving up on its commercial international market share, mainly because it can’t or won’t compete with the newer American companies.

Arianespace’s Vega launches European satellite to study the Earth’s winds

9:18 am

Arianespace’s Vega rocket has successfully launched a European satellite dubbed Aeolus designed to study the Earth’s winds.

Funded by the European Space Agency and built by Airbus Defense and Space, the 480 million euro ($550 million) Aeolus mission is nearly two decades in the making. Since receiving ESA’s formal go-ahead in 2002, Aeolus has suffered numerous delays as engineers encountered problems with the mission’s laser instrument.

Aeolus will gather the first comprehensive worldwide measurements of wind speed — over oceans and land masses — from Earth’s surface to an altitude of nearly 100,000 feet (30 kilometers).

Data collected by the Aeolus satellite will be fed into numerical weather prediction models, replacing simulated “boundary conditions” in the computers models with near real-time measurements from space.

The updated leader board for the 2018 launch standings:

22 China
15 SpaceX
8 Russia
6 ULA
5 Arianespace

In the national race, the U.S. and China remained tied at 22.

SpaceX and Arianespace both launch multiple satellites

9:22 am

Capitalism in space: SpaceX and Arianespace both had successful early morning commercial launches today.

The Ariane 5 delivered 4 Galileo GPS satellites, while SpaceX placed in orbit 10 Iridium communications satellites. SpaceX also successfully recovered the first stage.

The leaders in the 2018 launch standings:

20 China
14 SpaceX
8 Russia
5 ULA
4 Japan
4 Arianespace

In the national rankings, the U.S. and China are once again tied, now at 20-20.

Arianespace lowers its launch forecast for 2018

9:29 am

Capitalism in space: Because of a launch miscue in January and a decision by India to delay a satellite launch, Arianespace today admitted that it will not meet its forecast of fourteen launches in 2018.

Arianespace, majority-owned by a joint venture of Airbus and Safran, has so far conducted only three launches, but expects a busier second half, CEO Stephane Israel said. He now expects around 11 satellite launches for the year.

There might be a similar number of launches in 2019, but it is too early to give a definitive forecast, Israel said, adding the company was now focusing on gaining customers for the lower cost Ariane 6 rocket due to debut in 2020.

The article states the launch cost for Ariane 6 will be 40% less than Ariane 5, which cost $100 million per satellite. This brings the per satellite price for Ariane 6 to $60 million, about what SpaceX presently charges. Whether that can compete with the prices that SpaceX and others will be charging in 2020, when Ariane 6 is expected to become operational, remains unknown.

Ariane 5 launches two satellites

11:06 pm

Europe’s Ariane 5 rocket today successfully placed two communications satellites in orbit, its first launch since January when the rocket placed two satellites in the wrong orbit.

Arianespace did launch a Soyuz rocket in the interim, but this launch signals the return to flight for Ariane 5.

The leaders in the 2018 launch standings:

10 China
7 SpaceX
4 Russia
3 Japan

Arianespace successfully places four communications satellites in orbit

9:28 pm

Using a Russian Soyuz rocket and launching from French Guiana Arianespace today successfully launched four communications satellites.

The leaders in the 2018 launch standings:

7 China
5 SpaceX
3 Japan
3 ULA
2 Russia
2 Arianespace

For the purpose of these rankings, I consider the Soyuz rocket, launched from French Guiana, an Arianespace vehicle, since it is marketed, assembled, and launched by that company.

Today’s Ariane 5 launch NOT a failure

4:31 pm

Arianespace’s first launch attempt in 2018 appears to have gotten the satellites into orbit, even though contact was lost during launch.

From the reports, it appears that contact was lost when the second stage began firing.

Before this, the Ariane 5 had completed 83 straight successful launches, a track record that Arianespace repeatedly touted as justification for its higher rates.

Update: Arianespace is now saying that though they had entirely lost contact with the rocket after the second stage fired, the satellite’s themselves reached orbit.

A few seconds after ignition of the upper stage, the second tracking station located in Natal, Brazil, did not acquire the launcher telemetry. This lack of telemetry lasted throughout the rest of powered flight.

Subsequently, both satellites were confirmed separated, acquired and they are on orbit. SES-14 and Al Yah 3 are communicating with their respective control centers. Both missions are continuing.

It appears that the SES-14 satellite can reach its planned orbit using its own engines. Al Yah 3’s status is less certain.

If these results hold up, I will then declare, for the purpose of my 2018 launch standings, that this launch is a success for Arianespace. Arianespace however will certainly not consider it so, and will need to figure out why it lost contact with its rocket and why the upper stage did not function as planned.
