SpaceX’s flight-proven Falcon 9 snags NASA launch contract, second of 2019
NASA has announced that SpaceX’s Falcon 9 rocket – using a flight-proven booster – will launch the ~300 kg (670 lb) Imaging X-ray Polarimetry Explorer (IXPE) spacecraft no earlier than April 2021.
Intriguingly, IXPE was originally planned to launch on Orbital ATK (now Northrop Grumman’s) Pegasus XL but NASA never followed through with a launch contract. The move to SpaceX’s Falcon 9 rocket is likely related to the extremely disruptive and expensive launch delays NASA’s Ionospheric Connection Explorer (ICON) spacecraft has suffered at the hands of its Pegasus XL rocket. Capable of launching less than 450 kg (1000 lb) to low Earth orbit, Pegasus XL has been lucky to launch annually over the last decade or so and carries a price tag of no less than $50M-$60M today.
To add to this: NASA says SpaceX can use a previously flown booster on this mission.
IXPE is a small satellite, but this launch contract is less than what NASA paid for for the still-pending Pegasus XL launch of ICON ($56.3M in a 2014 contract). Think about that… https://t.co/sJlWVMHC5c— Jeff Foust (@jeff_foust) July 8, 2019
Small rocket, huge delays
Defying its small size, Pegasus XL was originally scheduled to launch ICON in December 2017. Delayed by unspecified problems with launch vehicle hardware, the mission was pushed back an inexplicable 10 months to October 2018, where additional issues with the rocket again indefinitely scrubbed a launch attempt. In early 2019, the launch was tentatively scheduled for Q2 2019, while – as of July – ICON is not expected to launch before September 2019.
All said and done, in the increasingly unlikely event that Pegasus XL is ready for launch this September, the ICON spacecraft – ready for launch since late-2017 – will have been delayed more than 21 months by problems with the rocket.
Again, for the small-scale performance of Pegasus XL, the rocket still carries a price tag of more than $50M – NASA’s ICON launch contract was valued at more than $56M. Conscious of this, SpaceX has managed to sway NASA to launch the small IXPE spacecraft on a flight-proven Falcon 9 at a cost of just $50.3 million, easily the lowest Falcon 9 launch contract cost ever publicized.
In recent months, SpaceX executives have made comments indicating that Falcon 9’s default base price – likely assuming a flight-proven booster – is now as low as $50M. July 8th’s NASA launch contract is the first direct confirmation of that exceptionally affordable pricing, likely also indicating that the base price for Falcon 9 is even lower for commercial customers with less stringent requirements.
Barring an unexpected contract between now and IXPE’s expected April 2021 launch, the mission will probably be the first time that a dedicated flight-proven SpaceX rocket launches a scientific spacecraft for NASA. SpaceX’s next dedicated NASA launch – the ESA-built Sentinel 6A spacecraft – is scheduled to no earlier than November 2020 and is likely to fly on a new Falcon 9 booster.
In April 2019, NASA awarded SpaceX $69M for Falcon 9 to launch the agency’s Double Asteroid Redirect Test (DART) – an asteroid-impactor spacecraft – no earlier than June 2021. IXME is SpaceX’s second NASA launch contract win of 2019.
According to NASA, “IXPE will fly three space telescopes with sensitive detectors capable of measuring the polarization of cosmic X-rays, allowing scientists to answer fundamental questions about these turbulent environments where gravitational, electric and magnetic fields are at their limits.”

Tesla Full Self-Driving’s newest behavior is the perfect answer to aggressive cars
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.
A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:
Tesla appears to be implementing some sort of feature that will now pull over if someone is tailgating you to let the car by
Really cool feature, definitely get a lot of this from those who think they drive race cars

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.
This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.
FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.
Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.
When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:
What has happened to Mad Max?
At one point it was going 32 in a 35. Traffic ahead had pulled away considerably https://t.co/bjKvaMVTNX pic.twitter.com/aaZSWmLu5v

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.
Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla Megapack powers $1.1B AI data center project in Brazil
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.
The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.
According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.
“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.
The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.
The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink powers Europe’s first satellite-to-phone service with O2 partnership
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.
Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.
The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.
Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.
By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.
Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.
Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.
For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
