SpaceX gears up for busiest April yet

Published

on

SpaceX says it’s finished encapsulating 40 spacecraft inside a Falcon 9 rocket’s payload fairing, paving the way for the company’s fourth Transporter rideshare mission early next month.

Scheduled to lift off no earlier than 12:24 pm EDT (16:24 UTC) on Friday, April 1st, Transporter-4 will be the first of as many as six Falcon 9 launches in April. In fact, SpaceX actually wants to launch all but one of those six missions in the first 19 days of the month – tying its existing cadence record if the company can pull it off.

SpaceX managed to complete a record five orbital Falcon 9 launches in ~18.5 days in December 2021. Including one additional mission in late November, SpaceX actually launched six times in 27 days. The company then nearly repeated that record the very next month, launching six times in 28 days in January and February 2022. SpaceX has yet to literally launch six times in the same month but it’s already more than demonstrated the ability to do so if the timing is right.

April might be that month. Following Transporter-4, SpaceX has two Crew Dragon missions – Axiom-1 with four private astronauts and Crew-4 with four government astronauts – scheduled to launch from Kennedy Space Center Pad 39A on April 6th and April 19th. In the middle, SpaceX intends to launch Starlink 4-14 – the month’s only planned Starlink mission – on April 14th. On April 15th, SpaceX is scheduled to launch the National Reconnaissance Office’s (NRO) NROL-85 spy satellite out of California’s Vandenberg Space Force Base. Finally, SpaceX could launch Egypt’s Nilesat 301 geostationary communications satellite on April 30th.

While it won’t break its internal cadence record, April should continue to demonstrate that five or six launches in one month are increasingly becoming the norm for SpaceX – not just some one-off feat requiring an extraordinary effort. That’s made even more clear by the fact that three of April’s launches will either be carrying humans or military spy satellites – both requiring the utmost care and explicit approval from two of SpaceX’s strictest customers.

Curiously, SpaceX has decided to recover Transporter-4’s Falcon 9 booster at sea despite a relatively small payload of just 40 satellites, likely meaning that the mission will require the rocket’s upper stage to perform at least three or four burns in orbit. One payload in particular – Germany’s EnMAP Earth observation satellite – both weighs far more than any other satellite aboard (~900 kg or ~2000 lb) and will likely take precedence, meaning that it will probably be delivered to a very specific orbit at the end of the mission’s deployment sequence.

Extra burns and longer coasts in orbit require significantly more propellant, which quickly cuts into the unforgiving margins needed for return-to-launch-site (RTLS) Falcon booster landings. In April, only NROL-85 will permit an RTLS landing, meaning that all five other launches will need to share SpaceX’s two East Coast drone ships – not impossible but far from easy. SpaceX’s record drone ship turnaround time is 13 days, while Starlink 4-14 will require a 13-day turnaround and Crew-4 a 14-day turnaround almost simultaneously.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.

Tesla launches improved Model 3 in China with V2L, new interior option

Tesla has launched its newest iteration of the Model 3 in China with a slew of new features, including the highly requested V2L (vehicle-to-load) feature and a new interior option.

The Model 3 now has a 16″ front touchscreen with improved resolution, a black headliner, V2L capabilities, Zen Grey interior in the Premium and Performance trims, as the White option has officially been discontinued, and 19″ Dark Nova Wheels, which are standard on the Model 3 Premium only.

The touchscreen in the U.S. version of the Model 3 is just 15.4″, so the newly upgraded screen is .6″ larger. Additionally, the Black Headliner, now standard on Model Y vehicles in the U.S., is coming to China.

Additionally, Tesla’s decision to end the white interior option has also made its way to the Asian market, as Zen Grey is the lighter color consumers can now go with. It is slightly different from the previously offered White option:

These options are available in China, Australia, and New Zealand as well, as Giga Shanghai serves those markets, bringing its mass-market vehicles to those countries in the South Pacific.

The Model 3 trims are now priced at:

  • Rear-Wheel-Drive – 235,500 yuan (~$35,000)
  • Long Range Rear-Wheel-Drive – 259,500 yuan ($38,700)
  • Long Range All-Wheel-Drive – 285,500 yuan (~$42,600)
  • Performance – 339,500 yuan (~$50,600)

These features have yet to make their way to the U.S., which might upset some buyers, but it is probably a good sign that Tesla will bring these changes to U.S. trims sometime next year. Potentially, these could come even sooner, as they could be used to stimulate demand for the year-end sales push.

Nevertheless, when things start at Giga Shanghai, they usually end up in the U.S. market. Tesla has also already started to install things like the Black Headliner and larger touchscreen in certain U.S.-built vehicles, so these things will be easy to implement across other vehicles in the lineup.
