[Press Release] NILESAT-301 SATELLITE TO BE BUILT BY THALES ALENIA SPACE

Cannes, December 4, 2019 – Thales Alenia Space, a Joint Venture between Thales (67%) and Leonardo (33%), announced today that it has signed a contract with the Egyptian operator Nilesat to build the Nilesat-301 geostationary communications satellite, winning the contract against an international field of competitors.

Positioned at 7° West, Nilesat-301 will work with Nilesat-201 to provide Ku-band services for the Middle East and North Africa. Nilesat-301 will also help extend the company’s provision of Ku-band communications and direct digital broadcasting services in two new large regions of Africa, while also providing broadband Ka-band connectivity over all of Egypt.

As prime contractor, Thales Alenia Space will be responsible for satellite design, production, testing and in-orbit acceptance tests. Thales Alenia Space will also provide satellite control system for Nilesat in both Cairo and Alexandria.

The satellite is based on the Spacebus 4000-B2 platform and will weigh about 4 metric tons at launch, which is scheduled for the first quarter of 2022. It offers a design life exceeding 15 years.

Following Nilesat-201, Nilesat-301 is the second geostationary communications satellite built by Thales Alenia Space for Nilesat. It is also the fourth payload developed by Thales Alenia Space for the Egyptian operator.

[Egypt Independent] Egypt signs contract to build new satellite ‘NileSat 301’
Al-Masry Al-Youm
December 3, 2019

Egyptian Satellite Company “NileSat” on Tuesday signed a contract to manufacture and launch the new satellite “NileSat 301,” alongside French aerospace company Thales Alenia Space.
...
The new satellite will launch in January 2022, replacing “NileSat 201,” which ends in 2028, according to Anis.
...
NileSat 301 has a default lifespan of 15 years and weighs 4.1 tons, Anis explained while discussing the technical capabilities of the new satellite. New frequencies were also added, which were obtained recently by the company under agreements signed with French company Eutelsat.

The new satellite will expand its coverage, Anis went on to say, noting that in addition to the areas covered by the current satellite, NileSat301 will also cover countries in the south of the continent and along the Nile basin.

SFN Launch Schedule update, March 25 (one of many):
Nilesat 301 launch on April 30, 2022 from Cape Canaveral SFS SLC-40, with ASDS landing.



Cross-post:
It's Nilesat-301.
0450-EX-ST-2022, Mission 1581   NET Apr. 22
From Florida
ASDS  North  27  46  48  West  73  38  10
With landing at that place it could be any GTO sat or even the O3b mPOWER mission 1 which is supposedly not expendable and needs low inclination so a launch straight out to the east would also be needed.
Nilesat-301, SES-22, and the first mPower launch are the only Falcon 9 launches that fit the bill for April/second annual quarter, according to our current NSF launch schedule.

The first two will be overseas deliveries from Thales Alenia, and the third will be delivered from Boeing.

If there are no corporate announcements, then watching for heavy cargo aircraft landing at one of the Space Coast airports would be an option.



Edit/add:

As regards to the first stage and whether or not there will be a Static Fire:

Assuming that 1069.2 does not yet make its return to flight, the logical choice, by order of previous duty, is 1052.5.  It last launched and landed on March 9.

If 1052.5, there will be no Static Fire required, unless the customer chooses and pays for the service.

Other possible choices: 1051.13 and 1060.12.  Also, there would be 1061.8, assuming a successful launch and landing of 1061.7 in early April.  They do not require Static Fire either.

Not available: 1058.12, 1062.5, 1063.5, 1067.4, and 1071.2.

Apparently being held for the upcoming expendable O3b mPower triplet launch: 1049.11.  See https://nextspaceflight.com/launches/details/2600 .

Nilesat-301 has recently been placed inside its container & is now ready for departure. It will leave Cannes’ plant in the upcoming weeks, heading for Fos sur Mer to take the ship to Cape Canaveral. Fair wind to our satellite & looking forward to the launch!

Huh, I thought the assumption was that was being held for the second O3b mPower launch, explicitly stated by the customer to be expendable.

Does that mean they'll be throwing away B1051 too?

My best guess is yes. I believe B1051 is one of the older Block 5 boosters that took a bit more time to prepare for its next flight.

I think other boosters from B1058 onward had some upgrades to allow them to have quicker turnaround times.

Next Spaceflight, updated April 23, lists the Falcon 9 first stage as 1049.11 and expendable.

A surprising choice at first thought, but consider.

With regards to launch vehicle fitness, there will (almost certainly) be a Static Fire before launch, as was standard for the pre-1050 boosters.

The first stage will provide more performance towards orbital velocity than it normally does.

Therefore, the second stage will provide greater delta-velocity from the initial parking orbit to the geosynchronous transfer orbit.

The spacecraft will use less propellant to reach GEO, and therefore have more for lifetime station-keeping in GEO, and therefore also a longer service lifetime (assuming no other difficulties).

Since Nilesat 301 is 4.1 tons, and taking into consideration the expendable profile, I'm estimating the GTO apogee to be about 68,000 km with the inclination at around 20 degrees. This gives a final delta-v to GEO of ~1,537 m/s (assuming a 200-kilometer perigee).

That will be a very nice GTO ride indeed.  There are so few GTO missions it seems.

Expending the older Block 5's makes sense as they add to the fleet.  RTLS and Expendable flights will really help keep up the launch cadence.

Get the payload fairings back and free up the ASDS for another flight.

Seems like SpaceX is spreading some of the payload mass of the 2 original O3b mPOWER missions over 3 missions instead, likely meaning they don't need to expend a booster to boost them higher now, explains why B1049-11 is now being expended on Nilesat 301 instead

Another thought springing from Nilesat 301 being the 1049.11 expendable launch, from SLC-40:

This may launch in late June, after Starlink 4-19 (NET June 10, likely from SLC-40), and perhaps SES-22 (June, also from SLC-40).

(Starlink 4-19 will be a "usual" Starlink northeastern trajectory launch with first stage ASDS landing.  SES-22 would launch due east, with ASDS first stage landing.)

If so, then after the Nilesat-301 launch, there is no need to hurry an ASDS with landed first stage back to Port Canaveral, to make a turnaround to catch one of the side boosters for USSF-44, also in late June, from LC-39A.

The two launch campaigns can proceed simultaneously, if necessary.
