CANAVERAL Air FORCS STATION, FL – SpaceX successfully relaunched the first 1st
recycled and upgraded Block 5 model of their workhorse Falcon 9 booster that
delivered an Indonesian comsat sailing to orbit overnight this morning,
Tuesday, Aug. 7, from the Florida Space Coast.
Just
minutes later the Falcon 9 first stage made a pinpoint rocket assisted re-landing
on a droneship waiting hundreds of mile offshore in the Atlantic Ocean. Overall
this counted as the second launch and second ocean landing for the Block 5
booster.
Liftoff
of the Merah Putih telecommunications satellite took place
right at the opening of the two-hour long launch window in the dead of night at
1:18 a.m. EDT (0518 GMT) Tuesday, Aug. 7, from seaside Space Launch Complex-40
on Cape Canaveral Air Force Station, FL.
The rocket put on a fabulous sky show that
delighted onlookers from near and far for many minutes due to the nearly complete absence of view
obscuring clouds.
technical glitches were encountered during the terminal countdown for the two
stage 229-foot tall (70-meter) Falcon 9
rocket.
The
successful soft landing set up the possibility of a first of its kind third
launch for this particular Block 5 Falcon 9 first stage – and counts as another
major milestone towards SpaceX CEO Elon Musk’s dream of rocket recycling and
slashing launch costs to a fraction of what’s been possible heretofore.
The
Block 5 is also the Falcon 9 version that will launch US and partner astronauts
to space aboard the Crew Dragon commercial crew spaceship sometime in 2019 – via
a development effort funded by NASA.
The
first commercial crew astronauts for the Crew Dragon and Boeing Starliner were
announced by NASA on Aug. 3.
The stunning
middle-of-the-night blastoff of the Falcon 9 carried the Merah Putih telecommunications satellite
to a geostationary transfer orbit for the nation of Indonesia.
just as planned and was deployed 32 minutes after liftoff.

week.
Falcon 9 launches and carried out 28 successful booster recoveries – 12 by land
and 16 by sea on ocean platform drone ships off both the Atlantic and Pacific
Coasts.
This was the 15th flight of a previously flown rocket booster.
The satellite was launched to geostationary transfer
orbit and eventually an altitude some 22,000 miles (36,000 km) above Earth.

SpaceX carried out the Atlantic ocean landing on the OCISLY drone
ship platform some 400 miles (60 km) off the East Coast of Florida.
The 5800 kg (12,780
pound) satellite was built by SSL (formerly Space
Systems/Loral) in Palo Alto, Ca., and completed ahead of schedule for Telkom
Indonesia, also known as PT Telkom.
Merah Putih will be located at 108 degrees East
longitude. “It is an all C-band
satellite that enhances both internet and telephone service for populations in
remote regions and will be used to offload backhaul for cellular service,” says
SSL.

as a replacement for Telkom-1 which mysteriously failed in orbit in August 2017.
The new name of Merah Putih is derived from the red and while
colors of the Indonesian flag.
The satellite has a design lifetime of 16 years or more.
It will serve the 17,000 islands of the Indonesian archipelago as
well India and other parts of South and
Southeast Asia. Satellites for the
“backbone” of telecommunications in Indonesia, along with other technologies,
such as submarine cable.
“Satellite plays a vital role in our
telecommunications infrastructure,” said Mr. Zulhelfi Abidin, Chief
Technology Officer of Telkom, in a statement.
“SSL has been an excellent spacecraft supplier
and has completed the satellite construction ahead of schedule. We look forward
to traveling to Florida to see the satellite launch later this summer.”
The satellite is based on the SSL
1300 series bus. which provides the
flexibility to support a broad range of applications and technology advances.
It is equipped with 60 C-band transponders. 36 transponders will
be used in Indonesia and the rest will be used for the Indian market.
“Merah Putih, which was completed ahead of schedule, will replace Telkom-1, at
108 degrees East, where it will expand on Telkom’s coverage to serve new
markets. Its all C-band payload will enhance both internet and telephone
service for populations in remote regions and offload backhaul for cellular
service.”
During Tuesday’s launch the rocket’s
first and second stages were fueled with liquid oxygen and RP-1 propellants and
the countdown led to ignition of all nine Merlin 1D first stage engines generating some 1.7 million
pounds of thrust at pad 40.
