SpaceX Countdowns to Eutelsat’s Nighttime Launch – Spaceflight Now
Stay streaming of the countdown and launch of the SpaceX Falcon 9 rocket from Area Launch Complicated 40 on the Area Power Station in Cape Canaveral, Florida. A Falcon 9 rocket will launch Eutelsat’s Hotbird 13G geostationary communications satellite tv for pc. Observe us Twitter.
SpaceX is poised to launch a Falcon 9 rocket Thursday morning from Cape Canaveral carrying Eutelsat’s Hotbird 13G tv broadcast satellite tv for pc. Liftoff is scheduled for the tip of the in a single day launch window at 1:22 a.m. EDT (0522 GMT). The primary stage of the Falcon 9 launch automobile can be geared toward touchdown an unmanned aerial automobile within the Atlantic Ocean.
Floor crews rolled the Falcon 9 into pad 40 at Area Power Station Cape Canaveral on Wednesday, a day after SpaceX launched the highly effective Falcon Heavy rocket from pad 39A a couple of miles up the coast. The 229-foot (70-meter) Falcon 9 was lifted vertically on pad 40 Wednesday afternoon forward of the evening launch window.
Forecasters with the U.S. Area Power’s forty fifth Climate Squadron are predicting a 90 p.c probability of favorable climate for takeoff, with a small probability of cumulus clouds that might pose a lightning menace.
Constructed by Airbus, the Hotbird 13G spacecraft, weighing about 10,000 kilos (4.5 metric tons), will broadcast a whole bunch of tv and radio channels throughout Europe, the Center East and North Africa. Hotbird 13G is the dual satellite tv for pc of Hotbird 13F, which was launched on October 15 on the earlier SpaceX Falcon 9 mission. The 2 Hotbirds are the primary satellites constructed on the brand new Airbus Eurostar Neo spacecraft design, which embody upgrades to propulsion, thermal management and electrical programs.
Throughout Thursday morning’s countdown, the Falcon 9 launcher can be stuffed with one million kilos of fuel and liquid oxygen within the remaining 35 minutes earlier than liftoff.
As soon as the groups have verified that every one technical and climate parameters are “inexperienced” for launch, the 9 Merlin 1D principal engines on the launch automobile’s first stage can be fired to life with an ignition fluid known as triethylaluminum/triethylborane, or TEA-TEB. As soon as the engines are at full throttle, the hydraulic clamps will open to launch the Falcon 9 for liftoff into area.
The 9 principal engines will generate 1.7 million kilos of thrust for about two and a half minutes, propelling the Falcon 9 and Eutelsat’s Hotbird 13G communications satellite tv for pc into the higher ambiance. Then, the booster stage — SpaceX fleet quantity B1067 — will disengage and separate from the Falcon 9 higher stage.
The rover will prolong its titanium lattice fins and chilly fuel thrusters to orientate for tail reentry into the ambiance earlier than re-engaging the engines for braking and remaining touchdown, aiming for a vertical descent to the Simply Learn Directions unmanned craft parked at roughly 420 miles (about 675 kilometers) east of Cape Canaveral.
The profitable touchdown of the rocket on the unmanned spacecraft will mark the completion of the launch automobile’s seventh flight into area. The booster made its debut on June 3, 2021, with the launch of the Dragon cargo mission to the Worldwide Area Station and carried two crews of astronauts into area as a part of NASA’s Crew-3 and Crew-4 missions. It additionally launched the Turksat 5B communications satellite tv for pc, one other area station replenishment mission, and most just lately a batch of Starlink Web satellites on September 18.
For the Hotbird 13G mission, the Falcon 9 rocket will hearth its higher stage engine twice to launch the spacecraft into an elliptical geostationary orbit with an apogee, or excessive level, greater than 30,000 miles (50,000 kilometers) above Earth.
Hotbird 13G will separate from the Falcon 9 rocket about 36 minutes after the mission ends.
After deploying from a Falcon 9 launch automobile to start its journey to geostationary orbit, Hotbird 13G deploys photo voltaic panels and makes use of PPS5000 plasma thrusters, developed by France’s Safran, throughout months of orbital ascent maneuvers to achieve a round geostationary orbit of greater than 22 000 miles (nearly 36,000 kilometers) above the equator.
The fuel-efficient plasma propulsion system depends on xenon and electrical energy to generate thrust, relatively than typical liquid rocket propellants comparable to hydrazine. This reduces the satellite tv for pc’s weight, permitting engineers to launch smaller rockets or add extra payloads to help extra communications energy for patrons.
However the ascent to orbit utilizing electrical propulsion takes longer than maneuvers utilizing typical rocket engines.
Hotbird 13G, like its predecessor Hotbird 13F, will orbit in line with Earth’s rotation at 13 levels east longitude.
By the center of subsequent 12 months, Hotbird 13G needs to be prepared for industrial operation to start a 15-year mission to broadcast tv applications for Eutelsat prospects. Due to enhancements in Eutelsat’s satellite tv for pc communications know-how, solely two new Hotbird satellites can be wanted to exchange the three growing old Hotbird spacecraft working at 13 levels east latitude.
Pascal Homsi, Chief Technical Officer of Eutelsat, stated the Hotbird fleet at 13 levels east latitude varieties the best capability satellite tv for pc broadcasting system overlaying the Europe, Center East and North Africa areas, delivering 1,000 TV channels to greater than 160 million properties. Hotbird 13F and 13G will broadcast alerts in Ku-band frequencies.
“We have now over 600 pay TV channels, 300 free-to-air channels, 450 high-definition channels and 14 ultra-high-definition channels broadcast from this flagship place at 13 levels east,” Homsi stated final month earlier than the launch of Hotbird 13F. “We are able to additionally present 500 radio stations and multimedia companies.”
The Hotbird 13G launch will mark SpaceX’s 51st mission in 2022 and the second in a sequence of three Falcon 9 flights for Eutelsat. The Eutelsat 10B communications satellite tv for pc, designed to supply web connectivity to airline passengers, was delivered from Europe to Cape Canaveral by boat final week for launch on a Falcon 9 rocket later this month.
