As the countdown for the launch of the world’s heaviest commercial communications satellite atop a Falcon Heavy rocket faced technical obstacles, SpaceX, undeterred, plans to make a second attempt on Friday. The scheduled liftoff from Kennedy Space Center’s pad 39A, carrying the Jupiter 3/EchoStar 24 satellite, is set for 11:04 p.m. EDT (0304 UTC Saturday). In Cape Canaveral, the U.S. Space Force’s 45th Weather Squadron has forecasted a 75 percent chance of suitable launch conditions within the 99-minute launch window.
On Wednesday, the Falcon Heavy was fully fueled, but with just one minute and five seconds remaining on the countdown, the launch director made the crucial decision to call for an abort. Initially, SpaceX targeted Thursday for the rescheduled launch, possibly setting the stage for a record-breaking doubleheader alongside a Falcon 9 from the neighboring pad 40. However, the launch was postponed by another day to address the rocket’s issues. On Friday afternoon, a reassuring Tweet from the company stated, “All systems are looking good.”
The Falcon Heavy’s twin side boosters, with two previous flights under their belt, will return to SpaceX’s Landing Zones 1 & 2. Unfortunately, the rocket’s core stage will be sacrificed, its full capacity dedicated to lofting the colossal satellite into a geostationary transfer orbit, without any hope of recovery.
Within the rocket’s payload fairing lies the Jupiter 3/EchoStar 24 satellite, positioned to claim the title of the heaviest commercial communications satellite ever sent into space. Tipping the scales at an impressive 9 metric tons, this satellite holds the potential to extend the coverage of the HughesNet satellite internet service to nearly 80 percent of the population residing across the continents of the Americas. Boasting 300 spot beams to precisely target coverage areas and possessing a whopping 500 Gbps of capacity, it is a technological marvel.
Sharyn Nerenberg, the vice president of corporate communications at EchoStar, explained that once launched, Jupiter 3 will undergo an orbit raising and testing process as it finds its orbital slot at 95 degrees West longitude. Falcon replace EchoStar’s Spaceway 3 satellite which is launched on Aug. 14, 2007. Nerenberg proudly emphasized, “The Hughes’ Jupiter fleet of satellites holds the distinction of being the largest Ka-band fleet across the Americas. It comprises the Jupiter 1 satellite, the Jupiter 2 satellite, three hosted payloads over Latin America, and soon, the Jupiter 3 satellite.”
The choice of the Falcon Heavy for this launch was no accident. Nerenberg justified the decision, citing the necessity of a heavy-lift rocket to carry such a massive satellite. In the last, Jupiter missions utilized Arianespace’s Ariane 5 in 2012 and ULA’s Atlas V rocket in 2016. “A geostationary satellite is tried and tested, excelling at providing dense broadband capacity precisely where our customers need it the most,” Nerenburg asserted confidently. “Jupiter 3 was custom-designed for that very purpose—to deliver the maximum capacity precisely where our customers require it.”
“Furthermore, Jupiter 3 will revolutionize cellular backhaul for mobile network operators, extending reach beyond their terrestrial towers, ensuring broader coverage,” Nerenberg continued. “It will also usher in a new era of aeronautical connectivity, providing high-speed WiFi in the skies for airplanes traversing North and South America.”
