Our Blue Ring Pathfinder hit all our mission objectives within the planned six-hour journey after being inserted into the desired orbit by New Glenn with an apogee of 19,300 km and a perigee of 2,400 km at a 30-degree inclination. GS2 and the BE-3U engines nailed insertion with a less than 1% deviation from our exact orbital injection target.

SpaceX Astronaut, Engineer, and Medical Officer Anna Menon (Anna Menon) played a critical role in the recent and historic Polaris Dawn mission (Polaris). Anna and her crewmates reached the highest orbit since the last Apollo flight in 1972, more than 50 years ago. They also depressurized the Dragon Capsule and performed the first commercial spacewalk before returning safely to Earth.

Shijian-31: a satellite with an orbit we have never seen before China launched Shijian-31 on June 16 from Xichang, officially described as a "space environment detection" mission. The orbital elements suggest more going on. The inclination 63.46° sits at the value where perigee advance goes to zero. Anyone who's tracked Molniya-class satellites will recognize that immediately. But the resemblance stops there. A classic Molniya parks its apogee over high northern latitudes and dwells for hours, that's the whole design premise. SJ-31's argument of perigee is 171°, which puts perigee near the equator and its apogee on the opposite side. (Image 1: SJ-31 at 171° argument of perigee vs. a generic Molniya at 270° argument of perigee.) So the long dwell isn't over any particular latitude — it's over altitude. Apogee reaches ~39,900 km, about 4,100 km above the operational GEO belt where comms and missile-warning satellites sit. Nearly a third of each 12.5-hour orbit is spent above that shell, crossing it twice per pass at a steep 63° angle. (Video 1: SJ-31's orbit visualized with example GEO assets.) It's also not fixed on one region. The period is just off a clean repeating ground track, so the sub-apogee point slowly drifts around the globe — sweeping past every longitude roughly once every 24 days. Net effect: an orbit that periodically looks down on the entire GEO belt from above, at an angle, on a rotating schedule, rather than fixating on one target. What's it actually doing up there?

2034 Earth–Venus–Mars opportunity looks promising. 10–15 on-orbit refueling operations may be needed to make a crewed ship full. Most can be done at an altitude of 180–200 km, made possible by Starship’s size. The final refueling may be performed at a higher altitude of ~2000 km, just below the Van Allen belt. Earth departure on 2034-08-21 from 2000 km orbit. A Trans-Venus Injection burn of ~3.7 km/s will place the ship on an Earth–Venus–Earth free-return trajectory. Venus flyby is expected on 2034-12-19, 120 days after departure. Two weeks before the encounter, if the mission proceeds as planned, a 25-m/s maneuver will shift the trajectory from Earth-return to Mars-bound. If not, the ship will free return to Earth in September 2035. The Venus gravity assist will send the ship into another Earth free-return trajectory, with Mars flyby around 2035-06-02. One week before reaching Mars, a system health check will determine whether to commit to Mars Orbit Insertion. If it’s GO, a small 10-m/s manuever will put the ship to less than 100 km altitude periapsis. Otherwise, a Mars flyby will lead to an Earth return in May 2036. The ship will enter the Martian atmosphere at about 9.4 km/s, performing an aerobrake to slow to 4.88 km/s and capture into a 100x140000 km, 7-day period high elliptical orbit. At apoapsis, a 50-m/s plane change will align the inclination with Mars’ equator, followed by additional aerobraking to remove about 650 m/s of velocity, placing the spacecraft in a 120x6128 km orbit. A 550-m/s burn at 6128 km altitude will then adjust the trajectory into Phobos orbit. The ship will stay at Phobos for about 7 days. The Mars–Phobos L1 point is only about two miles above Phobos’ surface, and Mars would dominate nearly half the sky, appearing about 80 times larger than the Moon from Earth. The ship will depart for Deimos afterward. Two burns totaling roughly 750 m/s will transfer the ship from Phobos to Deimos. And the ship will stay at Deimos for 7 days more. From Deimos, the ship will raise its apoapsis to form a 20000x140000 km altitude, 7-day orbit, requiring about 420 m/s of delta-v. At apogee, a 50-m/s burn will adjust inclination and lower periapsis to ~500 km for final Trans-Earth Injection. If time and propellant allow, the orbit can be aligned to a polar inclination for Mars ice-cap observations before departure. A Trans-Earth Injection burn at 500 km altitude, requiring 1.5–1.6 km/s of delta-v in early July 2035. If departure on the first days in July, Earth arrival is expected in December 2035. If missed that window, a March 2036 arrival may look more feasible. Nominal mission duration: 490 days, with 30 days in Mars orbit and 14 days at Phobos and Deimos. Two planets, two moons for 3.7+0.025+0.010+0.05+0.42+0.55+0.75+1.55=7.06 km/s Δv

And first commercial astronaut, we've now done many astronaut missions. I think it won't be long before we get past 100 astronauts to orbit and back. So, Dragon has been an amazing vehicle. So, we've flown 78 crew members to date. And it's been an epic success. So, I'd like to say congrats also to the Dragon team. Excellent work."

Elon Musk explains how Starlink works? "I think there's several 1000 satellites in low Earth orbit, and they're moving around 25 times the speed of sound in these zipping around the Earth, basically. And they're at an altitude of about 550 kilometers, which is called generally low earth orbit, because they're at low Earth orbit. Their latency is low because the distances is not that far, compared to Geo stationary satellite, 36,000 kilometers. So you've got 1000s of satellites providing low latency, high speed internet throughout the world, and they are interconnected as well. So there are laser links between the satellites. So it forms sort of a laser mesh, so that if, let's say if cables are damaged or cut, like fiber cables, the satellites can communicate between each other and provide connectivity. For example, when the Red Sea cables were cut, I think a few months ago, the Starlink satellite network, continued to function."
